For a B2B division with customer-specific pricing, POS, and large order volumes, I’d put Shopify Plus, Adobe Commerce, and BigCommerce Enterprise on the shortlist. The right choice depends heavily on whether POS is a first-class requirement or B2B complexity is the dominant requirement.

1. Shopify Plus

I'd seriously consider Shopify Plus if you want the B2B operation and physical retail/POS operation to live in the same ecosystem.

Shopify's current B2B functionality supports customer/company-specific catalogs, fixed prices, volume pricing, quantity rules, and direct catalog assignment to companies and locations on Plus. Shopify Plus also includes Shopify POS Pro. Shopify Help Center Shopify Help Center Shopify

The particularly interesting combination for you is:

B2B portal + DTC + retail POS + one commerce platform

Shopify Plus currently starts at $2,500/month on a 1-year term ($2,300/month on a 3-year term), although higher-complexity businesses can have variable platform fees. Shopify Shopify Help Center

2. Adobe Commerce

I'd put Adobe Commerce high on the list if your B2B pricing model is genuinely complicated.

Adobe supports company-specific shared catalogs and pricing, company accounts with multiple buyers/roles, purchasing permissions, quick ordering, negotiated quotes, and B2B/B2C from the same platform. Adobe also says its catalog services can handle millions of SKUs and thousands of prices per SKU. Experience League Experience League Adobe Business

That makes it particularly interesting if you have things like:

• Thousands of customers with different price agreements
• Contract pricing
• Large SKU counts
• Complex customer hierarchies
• Quote/approval workflows
• ERP-driven pricing
• Multiple websites/brands
• Highly customized B2B workflows

The tradeoff is implementation and operational complexity. POS isn't as naturally integrated into the core experience as Shopify's ecosystem, so I'd expect more integration work.

3. BigCommerce Enterprise

BigCommerce Enterprise is another strong candidate, particularly if you want substantial B2B functionality without going as deeply into a custom Adobe Commerce implementation.

Its higher-tier offering supports SKU-level Price Lists for customer groups, while BigCommerce also supports integrations with POS systems such as Square, Clover, and others. Its current Performance tier is aimed at $1M+ annual sales and uses custom pricing. BigCommerce BigCommerce

How I'd narrow it down

The key question I'd ask is where your complexity lives:

• POS + omnichannel + relatively straightforward B2B pricing → Shopify Plus
• Very complex pricing/catalog/customer structures → Adobe Commerce
• Strong B2B + headless/API flexibility + less dependence on a single ecosystem → BigCommerce Enterprise

One important distinction: "large order volumes" can mean two very different things. If you mean lots of orders per day, that's primarily a scalability/operations question. If you mean customers placing enormous orders with thousands of line items, that's more of a B2B UX, ERP integration, quick-order, and checkout architecture question.

If you tell me roughly annual B2B revenue, number of SKUs, number of B2B customers, number of physical POS locations, ERP (e.g. SAP/NetSuite/Dynamics), and how individualized your customer pricing is, I can build a much more useful Shopify Plus vs Adobe Commerce vs BigCommerce architecture comparison for your situation.

2. Adobe Commerce

I'd put Adobe Commerce high on the list if your B2B pricing model is genuinely complicated.

For a B2B division with customer-specific pricing, POS, and large order volumes, I’d put Shopify Plus, Adobe Commerce, and BigCommerce Enterprise on the shortlist. The right choice depends heavily on how complex your pricing/order rules are and how tightly POS needs to integrate with B2B.

1. Shopify Plus — particularly worth investigating

Shopify has expanded its native B2B functionality considerably. B2B catalogs can now provide customer-specific products/pricing, quantity rules and volume pricing; Plus adds unlimited B2B catalogs and direct assignment to individual companies/locations. help.shopify.com

The big advantage in your situation is POS: Shopify is designed around a common commerce platform spanning online, retail/POS and B2B. Shopify Plus currently starts at $2,500/month on a 1-year term, with variable pricing possible for more complex structures. www.shopify.com

One caveat: if your "custom pricing" means thousands of negotiated price lists, highly individualized contracts, complicated pricing formulas, or extensive sales-rep intervention, I'd pressure-test Shopify carefully rather than assuming its catalog model will handle everything.

Shopify Plus B2B overview

2. Adobe Commerce — worth considering if B2B complexity is extreme

Adobe Commerce's B2B functionality is unusually deep. It has company accounts, company hierarchies, shared catalogs, customer-specific pricing, negotiable quotes, purchase orders, approval rules, credit limits, requisition lists and quick ordering. experienceleague.adobe.com

For example, its shared catalogs can assign custom pricing to individual companies, while quotes allow buyers and sellers to negotiate quantities, discounts and shipping. experienceleague.adobe.com

I'd lean toward evaluating Adobe seriously if your B2B operation looks more like enterprise procurement than conventional wholesale ecommerce.

The tradeoff is implementation and ongoing technical complexity. Adobe itself is much more customizable, but that usually means more architecture, development and maintenance.

3. BigCommerce Enterprise

I'd also include BigCommerce in the RFP. Its appeal is that it provides a relatively open SaaS architecture with substantial B2B capabilities without requiring the same degree of platform ownership/custom development as Adobe.

It's particularly worth comparing if you have large catalogs, substantial B2B volume, complex integrations, and don't want to build around Shopify's ecosystem.

My suggested evaluation approach

Rather than choosing based on feature checklists, I'd give each vendor the same real-world B2B scenarios:

1. Customer A gets $8.25/unit
2. Customer B gets $7.90/unit above 1,000 units
3. Customer C has a negotiated contract price that differs by SKU
4. Customer D has 4 purchasing locations and 12 buyers
5. A buyer submits a 5,000-line order
6. Sales rep creates/edits a quote
7. Customer submits a PO requiring approval
8. Buyer walks into a physical location and needs their B2B price at POS
9. Inventory is shared between ecommerce, POS and warehouse
10. ERP needs to remain the system of record for customers, pricing, inventory and orders

That last group—especially #8–10—is where I'd expect the platforms to separate themselves.

If POS is a core part of the B2B operation, I'd put Shopify Plus at the top of the evaluation list, alongside Adobe Commerce if your pricing/procurement requirements are highly complex. Shopify explicitly positions Plus as a unified B2B/DTC/POS platform, while Adobe's native B2B tooling is deeper around company structures, quotes and procurement workflows. experienceleague.adobe.comwww.shopify.com

If you tell me roughly annual B2B revenue, number of SKUs, number of B2B customers, average order size, ERP (SAP/NetSuite/Dynamics/etc.), and whether POS is Shopify POS or an existing POS, I can narrow this down to a much more concrete architecture recommendation.

For B2B with custom/account pricing, POS, and large order volumes, I’d shortlist:

• Shopify Plus — strong unified B2B + POS, managed infrastructure, and increasingly robust native B2B pricing/catalog features. Shopify Shopify
• Adobe Commerce — worth considering if pricing rules, quoting, account hierarchies, and deep customization are unusually complex. experienceleague.adobe.com experienceleague.adobe.com
• BigCommerce B2B Edition — strong middle ground for complex B2B pricing and high-volume catalogs, particularly if you want SaaS rather than self-hosting. Shopify

Key question: if POS is a core requirement, Shopify Plus deserves especially close evaluation; if sophisticated B2B pricing/quoting and ERP integration dominate, Adobe Commerce becomes more compelling.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d shortlist Adobe Commerce, Shopify Plus, and BigCommerce Enterprise—but I’d put Adobe Commerce first if the B2B side is genuinely complex.

My shortlist

1. Adobe Commerce — my choice for complex B2B

Adobe Commerce is particularly strong when pricing and ordering rules get complicated.

It natively supports:

• Company-specific catalogs and pricing
• Multiple buyer accounts and organizational hierarchies
• Negotiated quotes
• Purchase-order workflows and approvals
• Quick ordering by SKU
• Requisition lists/reordering
• Different payment and shipping rules by company
• B2B and B2C on the same commerce platform

Adobe's current documentation specifically supports shared catalogs with custom pricing per company, negotiated quotes, purchase orders, and quick ordering. Experience League Experience League Experience League

That's a very good match if your sales reps might say:

"Customer A gets 17% off, Customer B gets a contracted price, Customer C has a different price at 500+ units, and this customer needs a PO approval."

Adobe can model that kind of complexity much more naturally than a primarily DTC-oriented platform.

2. Shopify Plus — strongest if POS is strategically important

Shopify Plus becomes very compelling if the same business needs excellent physical-store POS + ecommerce + B2B.

I'd favor Shopify Plus if your model looks like:

Retail stores / showrooms + ecommerce + B2B portal

rather than:

Highly complex B2B sales organization + ERP-driven pricing + negotiated contracts.

Shopify's B2B offering includes company-specific catalogs, pricing, payment terms, purchasing permissions and bulk ordering. Shopify

The big advantage is the unified Shopify ecosystem and POS. If your B2B customers also interact with physical locations, that can substantially simplify the architecture.

3. BigCommerce Enterprise — very worth evaluating

BigCommerce is probably the one I'd put into the RFP alongside Adobe and Shopify.

It's particularly interesting when you want sophisticated B2B functionality but don't want the degree of platform customization/complexity that Adobe can bring.

BigCommerce is strong for:

• Customer-specific pricing
• Large catalogs
• Bulk ordering
• Multiple storefronts
• ERP/PIM integrations
• Headless commerce
• Enterprise-scale order volumes

Its POS story isn't as inherently central as Shopify's, though, so I'd scrutinize the exact POS architecture rather than treating "POS integration" as a checkbox.

The bigger question: where does pricing live?

For your situation, this is probably more important than the ecommerce platform itself.

If you have thousands of B2B customers with negotiated pricing, I'd want to know whether pricing is mastered in:

ERP → Commerce

or

Commerce → ERP

or some hybrid model.

For example:

Customer → Contract → Price List → Volume Breaks → Product/SKU → Region → Sales Rep → Payment Terms

If that's your reality, I'd lean Adobe Commerce or BigCommerce, with the commerce platform tightly integrated to the ERP.

If pricing is relatively straightforward and POS is a major part of the business, I'd lean Shopify Plus.

My recommendation

I'd rank them like this based on what you've described:

1. Adobe Commerce — best overall for sophisticated B2B requirements
2. Shopify Plus — best if POS/unified retail experience is a major priority
3. BigCommerce Enterprise — excellent middle ground
4. OroCommerce — worth considering if you're overwhelmingly B2B and need a B2B-first platform

One important caveat: POS could change my #1 recommendation. If you tell me what POS you use today, what ERP you use (SAP, NetSuite, Dynamics, etc.), approximate annual B2B revenue/order volume, number of SKUs, and whether B2B customers have negotiated prices or formal contracts, I can give you a much more definitive Adobe vs Shopify Plus vs BigCommerce architecture recommendation.

For a B2B division with custom pricing, POS requirements, and large order volumes, I would focus less on “ecommerce platforms” and more on enterprise commerce platforms that can unify pricing, inventory, customer accounts, and order workflows. The best fit depends heavily on whether you are a distributor, manufacturer, retailer, or a B2B arm of an existing brand. Shopify KIBO Commerce

A shortlist I would evaluate:

Shopify Alkali## My likely recommendation by scenario

If you are a distributor/manufacturer

I would start with:

1. Adobe Commerce — if you have complex pricing, thousands of SKUs, multiple customer tiers, negotiated contracts, or ERP-driven pricing.
2. OroCommerce — if B2B workflows are the heart of the business.
3. BigCommerce Enterprise — if you want SaaS simplicity but still need serious B2B capability.

If you have retail stores + wholesale/B2B

I would look at:

1. Shopify Plus — especially if POS is a major requirement and you want one ecosystem for stores, online, and B2B.
2. BigCommerce — if the B2B side is more complex than the retail side.

If order volume is very large

Prioritize:

• ERP integration (SAP, Oracle, NetSuite, Dynamics, etc.)
• real-time inventory availability
• customer-specific price engines
• bulk ordering/reorder tools
• approval workflows
• EDI/punchout procurement support
• API scalability

A common mistake is choosing a platform that can “take orders” but cannot reliably handle contract pricing + customer entitlements + inventory + sales workflows at scale. Capterra

A few questions would narrow this down significantly:

1. What ERP are you running (SAP, NetSuite, Dynamics, custom, none)?
2. Is POS already in place, and which system?
3. Approximate scale: annual B2B revenue, number of customers, SKUs, and monthly orders?
4. Do customers have negotiated pricing/contracts, or mostly tiered volume pricing?
5. Are you selling direct to consumers too, or only B2B?

For a B2B division with custom pricing, POS, and large order volumes, I’d shortlist Shopify Plus, BigCommerce B2B Edition, and Adobe Commerce. The right choice depends heavily on how complicated your pricing and ERP/order workflows are.

My ranking

1. Shopify Plus — my default recommendation

If you want one platform across B2B ecommerce, DTC, and POS, I'd look very seriously at Shopify Plus.

Shopify now has native B2B functionality including company accounts, customer-specific catalogs, custom pricing, quantity rules, volume pricing, payment terms, and company/location-level purchasing. Plus adds unlimited B2B catalogs and direct assignment of catalogs to individual companies/locations. Shopify Help Center Shopify Help Center

The big advantage for your situation is POS. Shopify's retail ecosystem is considerably more mature than trying to bolt a POS onto a B2B-first platform.

I'd choose Shopify Plus if your requirements are roughly:

• B2B + DTC on the same commerce platform
• Physical locations / sales reps / POS
• Customer-specific price lists
• Volume discounts
• Large SKU/order volumes
• Strong integrations with ERP/WMS/CRM
• You want a relatively clean SaaS architecture
• You don't want your internal team maintaining the commerce platform

Plus currently starts around $2,500/month on a 1-year term, with variable pricing possible for more complex structures. Shopify

Potential weakness: If "custom pricing" means every customer can have highly individualized negotiated prices, contract pricing, quotes, approval workflows, complex account hierarchies, etc., you may need apps/custom development around Shopify.

2. BigCommerce B2B Edition — potentially the best B2B fit

I'd put BigCommerce B2B Edition at the top of the list if B2B is the primary business rather than POS/DTC.

Its B2B functionality is particularly strong: quote-to-cart, bulk ordering, purchase orders, net terms, requisition lists, approval workflows, company hierarchies and a dedicated buyer portal are available as part of its B2B offering. BigCommerce

That's attractive if your sales organization deals with things like:

Customer → locations → buyers → negotiated price lists → PO → approval → fulfillment

rather than simply:

Customer logs in → sees discounted catalog → checks out.

BigCommerce also supports SKU-level price lists for B2B customers at its higher tiers. BigCommerce

The tradeoff is POS. If physical retail/POS is a major part of the strategy, I'd generally favor Shopify.

3. Adobe Commerce — if your pricing/ERP requirements are really complicated

Adobe Commerce is the one I'd investigate if your B2B operation has very sophisticated commercial rules.

Adobe's B2B capabilities include:

• Company accounts
• Shared catalogs
• Company-specific pricing
• Negotiable quotes
• Purchase orders
• PO approval rules
• Quick Order by SKU
• Requisition lists
• Company-specific payment/shipping rules

Experience League Experience LeagueIts Shared Catalog functionality is particularly relevant to custom pricing: you can maintain gated catalogs with custom prices for different companies. Experience League

I'd lean Adobe if you have something like:

10,000+ customers × individualized contract pricing × multiple price books × complex promotions × ERP-driven availability × sophisticated approval/quote workflows × multiple websites/brands/countries.

The downside is complexity and total cost of ownership. You're generally taking on a substantially heavier implementation/integration/maintenance project than Shopify Plus.

What I'd do in your situation

If POS is genuinely important, my initial architecture shortlist would be:

#1 Shopify Plus
→ Best overall combination of B2B + POS + scale + ease of operation.

#2 BigCommerce B2B Edition
→ Best alternative if sophisticated B2B purchasing is more important than POS.

#3 Adobe Commerce
→ Best if pricing, quoting, account structures and ERP integration are exceptionally complex.

One important caveat: "custom pricing" is the requirement I'd investigate before selecting anything. There's a huge difference between:

• 10 customer price tiers
• 500 customer-specific price lists
• Contract pricing by SKU/customer/location
• Volume-based pricing
• Customer-specific negotiated prices
• ERP-calculated real-time pricing
• Quotes that become orders
• Different pricing based on sales rep, territory, quantity, contract, etc.

If you tell me (1) approximate annual B2B revenue/order volume, (2) number of B2B customers, (3) what POS you're using/wanting, (4) ERP—e.g. NetSuite, SAP, Dynamics, etc., and (5) how your custom pricing actually works, I can narrow this down to a recommended architecture and a Shopify Plus vs BigCommerce vs Adobe comparison specifically for your operation.

Yes. For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d narrow the shortlist to Shopify Plus, Adobe Commerce, and BigCommerce. My default recommendation would be Shopify Plus, but there are important exceptions.

My ranking

1. Shopify Plus — my first choice

If you want the B2B division to be easy for customers to order from while still supporting sophisticated pricing, Shopify Plus is probably where I'd start.

Shopify now has native B2B functionality including:

• Company accounts and multiple locations/buyers
• Customer/location-specific catalogs and pricing
• Volume pricing and quantity rules
• PO numbers
• Payment terms
• Quick bulk ordering
• Reordering
• Self-service purchasing
• ERP/API integrations
• Native Shopify POS

Shopify Plus adds unlimited B2B catalogs and the ability to assign catalogs directly to individual companies/locations, which is particularly relevant if every large customer has negotiated pricing. Shopify Help Center Shopify

The big advantage is one ecosystem for ecommerce + POS. You aren't trying to bolt a separate POS onto the ecommerce platform.

There is one caveat: B2B pricing/company functionality in POS isn't as cleanly native as the online B2B experience, and some B2B POS workflows may require an app/customization. Shopify's own ecosystem has apps specifically addressing customer-specific B2B pricing, quantity rules, PO numbers, and wholesale POS workflows. Shopify Community Shopify App Store

So if POS is a major part of the business, I'd specifically test your actual B2B POS workflow in a proof-of-concept rather than taking the marketing claims at face value.

shopify.com

2. Adobe Commerce — best if the B2B requirements are really complicated

I'd put Adobe Commerce ahead of Shopify if your B2B division has highly complex commercial rules.

Adobe has very strong native B2B concepts:

• Company accounts/hierarchies
• Shared catalogs
• Customer-specific pricing
• Negotiated quotes
• Purchase-order workflows
• Quick order by SKU
• Requisition lists
• Complex permissions
• Multiple websites/stores
• Extensive customization

For example, Adobe's Shared Catalog functionality allows custom pricing for different companies, while its Negotiable Quotes allow buyers and sellers to negotiate quantities and prices directly within the commerce workflow. Experience League Experience League

That's extremely attractive if your sales organization essentially operates ecommerce as an extension of a traditional B2B sales operation.

The tradeoff is that Adobe is considerably more of an enterprise IT project. You'll generally have more development, implementation, hosting/infrastructure, and ongoing maintenance considerations than with Shopify.

experienceleague.adobe.com

3. BigCommerce — the middle ground

I'd also put BigCommerce Enterprise on the RFP.

Its B2B functionality supports things like SKU-level price lists, customer groups, bulk discounts, buyer roles, invoice functionality and customer-requested quotes. BigCommerce

It's particularly interesting if you want an open/composable architecture and don't want to be as tightly tied to Shopify's ecosystem.

However, POS is the big distinction. BigCommerce intentionally takes an integration approach: it connects to POS platforms such as Clover, Square, Heartland Retail, Vend, etc., rather than providing the same tightly integrated first-party POS experience that Shopify does. BigCommerce

So if POS is central to the B2B operation, I'd lean Shopify.

What I'd choose based on your description

If you told me only:

"We have a B2B division, negotiated pricing, large orders, and need POS."

I'd shortlist:

1. Shopify Plus — 50% probability I'd select it
2. Adobe Commerce — 30%
3. BigCommerce Enterprise — 20%

But the decision changes dramatically depending on what "custom pricing" means.

For example:

Shopify Plus is best if:

• You want a modern, easy-to-use buyer experience
• B2B and DTC may eventually coexist
• POS is important
• You want fast implementation
• You have many customers but pricing rules aren't insanely complex
• You want a large app/integration ecosystem

Adobe Commerce is best if:

• Every customer has substantially different pricing
• Pricing is driven by complicated contractual rules
• You have sophisticated sales reps/account hierarchies
• Quotes and negotiated orders are fundamental
• You need deep ERP integration
• You have an internal/partner development team
• You are comfortable treating ecommerce as an enterprise software platform

BigCommerce is best if:

• You want strong B2B capabilities
• You want more architectural flexibility
• Your existing POS is important and you're happy integrating it
• You want to avoid some of the constraints of Shopify
• You have a more traditional B2B ecommerce architecture

One thing I'd investigate before choosing

Your ERP is probably more important than your ecommerce platform.

For a high-volume B2B operation, I'd map this flow before selecting anything:

ERP → customer → contract/pricing → inventory → ecommerce → order → credit/terms → fulfillment → POS → ERP

In particular, I'd want to know:

1. How many B2B customers?
2. How many unique price lists?
3. Is pricing customer-specific, SKU-specific, quantity-based, or contract-based?
4. Do customers have Net 30/60/90 terms?
5. Do customers place orders using PO numbers?
6. Are orders typically 10 lines or 500+ lines?
7. Do customers need CSV/Excel bulk ordering?
8. Do sales reps place orders on behalf of customers?
9. Does POS need to recognize the customer's negotiated price?
10. Which ERP/accounting system are you using?
11. How many physical locations?
12. Roughly how many orders/year and what is the average order value?

If you give me those 12 answers, I can give you a much more definitive Shopify Plus vs Adobe Commerce vs BigCommerce recommendation, including the architecture I'd use for the B2B + POS + ERP setup.

If you give me those 12 answers, I can give you a much more definitive Shopify Plus vs Adobe Commerce vs BigCommerce recommendation, including the architecture I'd use for the B2B + POS + ERP setup.

For a B2B division with customer-specific pricing, POS, and very large order volumes, I’d shortlist Adobe Commerce, Shopify Plus, and BigCommerce Enterprise—but my default recommendation would be Adobe Commerce if B2B complexity is the priority, and Shopify Plus if omnichannel/POS simplicity is the priority.

My shortlist

1. Adobe Commerce — my pick for a genuinely complex B2B operation

Adobe Commerce is particularly strong if each account can have its own catalog, price list, payment terms, purchasing rules, and negotiated pricing.

Its B2B functionality includes:

• Company accounts and hierarchies
• Customer-specific shared catalogs and pricing
• Negotiable quotes
• Quick Order
• Requisition lists
• Purchase-order workflows
• Company-specific payment/shipping methods

Adobe explicitly supports shared catalogs with custom prices for individual companies, and its Quick Order functionality is designed to accelerate SKU-heavy purchasing. Experience League Experience League

For very large orders, this is compelling because Adobe also has B2B components for SKU/CSV bulk ordering and purchase-order workflows. Experience League

Downside: it's substantially more implementation-heavy. You need a capable engineering/integration team, particularly if you're connecting ERP, PIM, OMS, pricing engines, and POS.

2. Shopify Plus — strongest if POS is strategically important

Shopify Plus deserves serious consideration if your B2B division needs to coexist with physical stores, sales reps, trade counters, or DTC.

Shopify's B2B functionality now includes company profiles, customer-specific catalogs, quantity rules, volume pricing, payment terms, and buyer permissions. Plus allows unlimited B2B catalogs with direct assignment to companies and locations. Shopify Help Center Shopify

The big advantage is the native Shopify POS ecosystem.

The catch is that I'd scrutinize your pricing requirements very carefully. If "custom pricing" means relatively straightforward customer/contract price lists and quantity breaks, Shopify can be excellent. If it means thousands of customers each having complicated negotiated price matrices, Adobe/BigCommerce may be a better architectural fit.

Shopify Plus currently starts around $2,500/month on a 1-year term, with variable platform fees possible for more complex structures. Shopify

3. BigCommerce Enterprise — the one I'd put into the bake-off

BigCommerce is worth including if you're predominantly B2B and don't need Shopify's particular POS ecosystem.

I'd especially investigate it if you have:

• Large product catalogs
• Lots of SKUs
• High-volume ordering
• Multiple price lists
• Multiple storefronts
• ERP-driven pricing/inventory
• Headless requirements

A current comparison of the major enterprise platforms positions BigCommerce particularly well for mid-market/industrial B2B, while Adobe is stronger for the most complex enterprise operations. Kensium

What I'd choose based on your description

If I were running the selection process, I'd rank them:

1. Adobe Commerce — if B2B is the core business and pricing/order complexity is extreme.

2. Shopify Plus — if you need B2B plus serious POS/retail/omnichannel, and want to minimize platform engineering.

3. BigCommerce Enterprise — if you're heavily B2B/industrial and want a SaaS platform with substantial B2B functionality without going as deep into Adobe's ecosystem.

One important caveat: POS changes the recommendation considerably. If your "POS" means hundreds of retail/counter locations where B2B customers walk in, identify themselves, receive their negotiated price, place a large order, and potentially have that order fulfilled later, I'd lean much more heavily toward Shopify Plus.

If instead POS is relatively secondary and the real problem is customer-specific contract pricing + enormous catalogs + ERP integration + quotes + PO workflows + huge order lines, I'd lean Adobe Commerce.

If you give me roughly annual GMV, number of B2B customers, number of SKUs, number of POS locations, ERP (SAP/NetSuite/Dynamics/etc.), and whether B2B and DTC share the same catalog, I can narrow this to a specific platform recommendation and architecture, including where each platform is likely to break down.

For a B2B division with customer-specific pricing, POS, and large order volumes, I’d shortlist Shopify Plus, Adobe Commerce, and BigCommerce—but the right choice depends heavily on how sophisticated your pricing/ERP/POS requirements are.

My initial ranking

🥇 I'd start with Shopify Plus

Shopify is particularly interesting if POS is a first-class requirement.

Shopify now has native B2B functionality for companies, company locations, customer-specific catalogs, volume pricing, quantity rules, payment terms, etc. Shopify Plus adds unlimited B2B catalogs and the ability to assign catalogs directly to individual companies/company locations. Shopify Help Center Shopify Help Center

For example, you can have:

• Customer A → 20% discount
• Customer B → negotiated SKU-specific pricing
• Customer C → $8/unit at 100+, $7/unit at 500+
• Customer D → minimum order of 50 units, sold in cases of 10
• Customer E → completely different assortment

Shopify supports these kinds of catalog, quantity, and volume-pricing rules natively. Shopify Help Center Shopify Help Center

And the big advantage is Shopify POS + B2B + ecommerce in the same ecosystem, rather than having to bolt a B2B storefront onto a separate POS system.

🥈 Adobe Commerce if your B2B is genuinely complex

Adobe Commerce is the one I'd investigate if you have very sophisticated pricing, quoting, account structures, ERP integration, multiple websites, or unusual order logic.

Its B2B functionality includes:

• Shared catalogs with company-specific pricing
• Quick Order by SKU/product name
• Requisition lists
• Negotiable quotes
• Company accounts
• Complex B2B payment/shipping configurations Experience League Experience League

That's powerful, but you're taking on substantially more implementation and technical complexity.

The biggest question is what do you mean by "POS"? Adobe Commerce itself isn't as compelling as Shopify if you need a polished native retail POS experience.

🥉 BigCommerce deserves a serious evaluation

BigCommerce would be my third platform to put into an RFP. It's particularly worth considering if your business is B2B-first rather than retail-first, and you want strong APIs/headless capabilities without going all the way into Adobe's implementation complexity.

The deciding factors I'd investigate

Before choosing, I'd score each platform against these 7 requirements:

1. Customer-specific pricing — Can pricing be assigned at customer/company/SKU level?
2. Price lists — How many price lists can you maintain and how easily can ERP pricing flow into them?
3. Large orders — Can customers upload 500–10,000 line items, order by SKU, or use quick-order functionality?
4. POS — Can your sales reps/retail locations see the same customer-specific pricing and account information?
5. ERP integration — Especially if you have SAP, NetSuite, Dynamics, etc.
6. Sales-rep ordering — Can reps place orders on behalf of customers while respecting their negotiated pricing/terms?
7. Performance — What happens when the catalog, customer count, price rules, and order volume get very large?

One important distinction

If by "custom pricing" you mean something like:

"Each B2B customer has a negotiated price for thousands of SKUs, and those prices are maintained in our ERP."

then I would not choose based on the storefront alone. The architecture of the ERP → pricing engine → ecommerce → POS integration becomes more important than the ecommerce platform itself.

If you tell me roughly:

• # of B2B customers
• # of SKUs
• orders/month
• average/largest order size
• what POS you're using today
• what ERP you're using
• whether B2B and DTC need to share one storefront

…I can give you a much more concrete Shopify Plus vs Adobe Commerce vs BigCommerce recommendation, including which one I'd pick for your situation.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d shortlist Adobe Commerce, Shopify Plus, and BigCommerce B2B—but the right choice depends heavily on how complex your pricing and sales workflows are.

My initial ranking

1. Adobe Commerce — my choice if B2B is the priority

Adobe Commerce has particularly strong native B2B functionality: company accounts, customer-specific shared catalogs/pricing, negotiated quotes, quick ordering, purchase orders, credit limits, and complex organizational structures. Experience League Experience League Experience League

Its shared catalogs are especially relevant to your use case: you can create different catalogs with different prices and make them available only to particular companies. Experience League Experience League

It also has native quote negotiation, including changing quantities, line-item discounts, shipping, etc.—useful if your "custom pricing" involves sales reps rather than simply predetermined price lists. Experience League Experience League

I'd lean Adobe if you have:

• Hundreds/thousands of B2B accounts
• Account-specific price lists
• Complex customer hierarchies
• Sales-rep-assisted ordering
• RFQs/negotiated quotes
• PO/payment terms
• Large catalogs
• ERP integration
• A need for extensive customization

The downside is implementation and ongoing technical complexity. You're buying a very capable platform, but you need a strong implementation team.

2. Shopify Plus — particularly compelling if POS is important

If the B2B division needs to operate alongside physical stores, sales counters, showrooms, or a retail operation, I'd take Shopify Plus very seriously.

Shopify B2B now supports custom catalogs/pricing, volume pricing, quantity rules and customer-specific product availability. On Plus, you can have unlimited catalogs and assign catalogs directly to company locations. Shopify Help Center Shopify Help Center

The big advantage is the broader Shopify ecosystem, particularly Shopify POS. If your requirement is "one ecosystem for ecommerce + B2B + physical POS," Shopify is substantially more attractive than Adobe.

There is one important consideration for your "large order volumes" requirement: Shopify currently documents a 500-line-item limit per B2B order/draft order. If your orders routinely contain more than 500 distinct SKUs/variants, that's something I'd test very carefully before choosing it. Shopify Help Center

3. BigCommerce B2B — worth putting in the RFP

BigCommerce is probably the platform I'd put between Shopify and Adobe in your evaluation.

It's particularly interesting when you want B2B-native capabilities without going all the way into Adobe's level of customization. It's worth evaluating for customer-specific pricing, account management, quoting, ERP integration and high-volume catalogs.

The tradeoff is that POS isn't its strongest native differentiator, so if POS is a core requirement rather than simply an integration requirement, Shopify deserves an advantage.

The bigger question: what does "custom pricing" mean?

This is the decision point I'd focus on.

If you mean:

Customer A gets $12, Customer B gets $10, Customer C gets $8, and those prices are maintained in the system.

Then Shopify Plus or BigCommerce could be excellent.

If you mean:

Each customer has negotiated contracts, multiple locations, different price books, quantity breaks, rebates, sales-rep overrides, quotes, approval workflows, PO terms, and potentially different products available to each location.

Then I'd put Adobe Commerce at the top of the list.

Adobe's B2B model was specifically built around company accounts and customized catalogs/pricing. Experience League Experience League

What I'd do in your situation

I'd run an RFP against these three:

1. Adobe Commerce — benchmark for B2B depth.
2. Shopify Plus — benchmark for POS, usability and operational simplicity.
3. BigCommerce B2B — benchmark for B2B capability vs. implementation cost.

And I would not select the platform based primarily on storefront features.

I'd make the vendors demonstrate your actual workflow:

Customer → company/location → login → customer-specific catalog → contracted price → volume discount → large cart → PO/credit terms → checkout → ERP → fulfillment → POS/order history.

That's where the platforms will really separate.

If you tell me (1) approximate annual B2B revenue/order volume, (2) number of SKUs, (3) number of B2B customers, (4) what POS you use today, and (5) ERP—e.g. SAP, NetSuite, Dynamics, Epicor, etc., I can narrow this down to a specific recommendation and a 3-platform scorecard, including implementation complexity and likely TCO.

It's particularly interesting when you want B2B-native capabilities without going all the way into Adobe's level of customization. It's worth evaluating for customer-specific pricing, account management, quoting, ERP integration and high-volume catalogs.

The tradeoff is that POS isn't its strongest native differentiator, so if POS is a core requirement rather than simply an integration requirement, Shopify deserves an advantage.

The bigger question: what does "custom pricing" mean?

This is the decision point I'd focus on.

If you mean:

If you mean:

Then I'd put Adobe Commerce at the top of the list.

Adobe's B2B model was specifically built around company accounts and customized catalogs/pricing.

What I'd do in your situation

I'd run an RFP against these three:

For a B2B division with custom pricing, POS, and large order volumes, I’d shortlist Shopify Plus, Adobe Commerce, and BigCommerce Enterprise. The right choice depends heavily on how sophisticated your pricing/ERP/order workflows are.

My initial ranking

1. shopify.com — my default recommendation

If POS is genuinely important, I'd put Shopify Plus at the top of the list.

Shopify now has native B2B functionality including company accounts, customer/company-specific catalogs, fixed pricing, volume pricing, quantity rules, payment terms and B2B ordering. Plus adds unlimited catalogs and the ability to assign catalogs directly to individual companies/company locations. Shopify Help Center Shopify Help Center

It also has a major advantage if you're operating B2B + physical retail/POS + potentially DTC on the same platform. Shopify Plus supports up to 200 POS Pro locations. Shopify

I'd favor Shopify Plus if:

• You have physical sales/POS alongside ecommerce.
• You want one customer/inventory/order ecosystem.
• You want relatively quick implementation.
• Pricing can be handled through customer/company catalogs and integrations.
• You want strong UX without building a huge custom commerce stack.

The main caveat: if "custom pricing" means extremely complicated contract pricing, customer-specific price matrices, negotiated quotes, sophisticated sales-rep workflows, etc., I'd investigate Adobe more seriously.

2. business.adobe.com — best for very complex B2B

Adobe Commerce is probably the strongest candidate if the B2B operation is fundamentally ERP/sales-contract driven rather than retail driven.

Its B2B functionality includes company-specific shared catalogs and pricing, negotiated quotes, purchase-order approvals, quick ordering, requisition lists and company-level purchasing workflows. Experience League Experience League

That's particularly compelling if you have situations like:

Customer A gets SKU X for $47, Customer B gets it for $43, Customer C has a negotiated contract price, but only certain customers can buy certain SKUs, with approval thresholds and sales-rep-negotiated quotes.

Adobe is built to handle that kind of complexity.

The tradeoff is implementation/maintenance. It's considerably more of an enterprise commerce platform than Shopify, so I'd expect a larger implementation team and substantially more technical ownership.

3. bigcommerce.com — definitely worth evaluating

BigCommerce is an interesting middle ground. Its Enterprise offering targets high-volume businesses, and its higher-tier offering includes SKU-level price lists for customer groups. BigCommerce

I'd put it on the RFP if you want:

• Strong B2B functionality.
• Flexible pricing/catalog structures.
• Large catalog/order volumes.
• More architectural flexibility than Shopify.
• Less Adobe-style complexity.

The big question for your situation would be how tightly you need POS integrated with ecommerce. That's where Shopify has a particularly strong story.

What I'd choose

If I were running the evaluation, I'd probably narrow it to:

Shopify Plus vs. Adobe Commerce, with BigCommerce as the third finalist.

I'd choose Shopify Plus if the business looks like:

B2B + POS + ecommerce + large volume + desire for operational simplicity

I'd choose Adobe Commerce if it looks like:

Complex B2B contracts + thousands of customer-specific prices + sophisticated quoting/approvals + ERP-driven sales processes

And I'd choose BigCommerce if you want a strong B2B commerce platform and find its architecture/integration model a better fit than either of those.

One important point: don't evaluate these primarily on storefront features. For your use case, I'd build the RFP around the pricing engine, ERP integration, inventory/order orchestration, POS, customer hierarchy, and high-volume order entry.

If you tell me roughly annual revenue/order volume, number of SKUs, number of B2B customers, ERP (SAP/NetSuite/Dynamics/etc.), POS system, and how complicated the customer-specific pricing is, I can give you a much more definitive recommendation and a Shopify Plus vs Adobe Commerce vs BigCommerce scorecard.

For a B2B division with customer-specific pricing, POS, and very large order volumes, I’d shortlist Shopify Plus, BigCommerce Enterprise, Adobe Commerce, and OroCommerce. The right choice depends heavily on how complex your pricing and ERP/order workflows are.

My shortlist

1. Shopify Plus — probably where I'd start

shopify.com

Shopify has become considerably stronger for B2B. Plus provides company/location accounts, customer-specific catalogs and pricing, volume pricing, quantity rules, payment terms, PO workflows, bulk ordering and APIs. Shopify Shopify App Store Shopify Help Center

The POS integration is a major differentiator if your B2B operation also has physical sales. Shopify Plus includes Shopify POS, and the Plus POS offering is designed for higher-volume/complex businesses. Shopify Shopify

The caveat I'd investigate carefully: B2B-specific company pricing isn't automatically available through Shopify POS in every scenario. Shopify's own documentation says company-specific B2B prices aren't available for retail purchases through POS, so you may need a specialized POS/B2B workflow or app depending on how your sales reps transact. Shopify Help Center

I'd choose Shopify Plus if:

• You want B2B + DTC + POS on one platform.
• Your pricing rules are sophisticated but not completely bespoke.
• You value implementation speed and a large integration ecosystem.
• You expect significant traffic/order volume.
• You want to minimize infrastructure/DevOps.

2. BigCommerce Enterprise — strong B2B contender

BigCommerce is worth putting through the same evaluation, particularly if B2B is more important than having a first-party POS ecosystem.

Its strengths are complex catalogs, customer-specific pricing, B2B workflows, APIs/headless capabilities and enterprise scalability. Shopify's own 2026 comparison characterizes BigCommerce as having strong native B2B/international capabilities. Shopify

I'd put BigCommerce ahead of Shopify if you have unusually complicated B2B catalog/pricing requirements and are comfortable assembling your POS and other components around the commerce platform.

3. Adobe Commerce — if the business rules are really complicated

Adobe Commerce is the option I'd investigate if you're talking about things like:

• thousands of customer-specific price lists
• complicated contract pricing
• negotiated quotes
• account hierarchies
• multiple warehouses/business units
• sophisticated approval workflows
• complex ERP integration
• highly customized checkout/order logic
• significant in-house engineering resources

Adobe's B2B capabilities are deep, but the tradeoff is implementation and ongoing technical complexity. Shopify's 2026 comparison similarly positions Adobe toward large enterprises with in-house technical teams and deep customization requirements. Shopify

4. OroCommerce — an interesting dark horse

If this is primarily a B2B business rather than a B2C business adding wholesale, I'd also put OroCommerce on the RFP.

It is purpose-built around B2B concepts such as company hierarchies, RFQs, quoting, complex pricing and organizational purchasing. Shopify's current B2B platform comparison specifically highlights Oro's B2B-first pricing and RFQ/quoting capabilities. Shopify

The downside is that POS isn't its strength, so I wouldn't make it the first choice if physical/POS selling is central to your strategy.

What I'd recommend

If I were running the selection process, I'd probably rank them:

Shopify Plus → BigCommerce Enterprise → Adobe Commerce → OroCommerce

But there's an important distinction:

If POS is a core part of the B2B operation, Shopify Plus moves substantially ahead. If POS is secondary and your pricing/order logic is extremely complex, Adobe or BigCommerce becomes more attractive.

And I would not choose based primarily on advertised order-volume limits. At enterprise scale, the more important question is how the platform handles your specific transaction model: large carts, bulk ordering, concurrent buyers, inventory reservations, ERP synchronization, pricing calculation, and order ingestion.

The 6 things I'd test in an RFP

I'd give each vendor the exact same scenarios:

1. Customer A gets $42/unit; Customer B gets $37/unit; Customer C gets a negotiated contract price.
2. Customer A orders 10,000 units and gets additional volume breaks at 1,000 / 5,000 / 10,000.
3. A salesperson creates that order in POS while applying the customer's B2B pricing.
4. Customer has 20 locations and 50 buyers, each with different purchasing permissions.
5. Order goes into your ERP with the correct customer, location, contract price, PO number, inventory allocation and tax treatment.
6. Run the same scenario at your peak concurrent traffic/order volume, not just a normal demo.

That exercise will tell you much more than a feature comparison.

If you tell me your approximate annual GMV/order volume, average B2B order size, number of SKUs/customers, ERP (SAP, NetSuite, Dynamics, etc.), and what POS you're using today, I can narrow this to a specific recommendation and architecture.

Yes. For the combination you described — B2B, customer-specific pricing, POS, and very large order volumes — I’d put Shopify Plus, Adobe Commerce, and BigCommerce Enterprise on the shortlist, with Shopify Plus as the first platform I’d evaluate.

My initial ranking

1. Shopify Plus — probably my first choice

Shopify has become substantially more compelling for B2B. Its native B2B functionality supports company accounts, multiple buyers/locations, customer-specific catalogs and pricing, quantity rules, volume pricing, payment terms, and bulk purchasing. Shopify also puts B2B, DTC and POS on the same platform. Shopify Shopify App Store

The important advantage for your use case is the unified commerce model. If the same products/inventory need to move through:

• B2B ecommerce
• retail ecommerce
• physical POS
• sales reps/manual orders
• large wholesale orders

...Shopify is particularly attractive.

Shopify has also expanded B2B capabilities beyond Plus, although Plus retains the more sophisticated capabilities such as unlimited catalogs and direct catalog assignment to companies/locations. Shopify Shopify

shopify.com

2. Adobe Commerce — strongest if pricing/order logic is exceptionally complicated

I'd put Adobe Commerce ahead of Shopify if your B2B operation has things like:

• thousands of customer-specific price agreements
• complex contract pricing
• complicated company hierarchies
• negotiated quotes
• sophisticated approval workflows
• huge catalogs
• highly customized checkout/order processes
• significant internal engineering resources

Adobe's B2B functionality has shared catalogs with company-specific pricing, negotiable quotes, company accounts, requisition lists, and purchase-order workflows. Experience League Experience League Experience League

It also has native B2B functionality for bulk ordering by SKU/CSV, purchase orders, quotes and requisition lists, which is quite relevant for large-volume buyers. Experience League

The tradeoff is implementation and ongoing technical complexity. Adobe itself is generally the better choice when the commerce platform needs to bend around your business, rather than when you want the business to operate largely within a standardized SaaS platform.

experienceleague.adobe.com

3. BigCommerce Enterprise — worth putting in the RFP

BigCommerce would be my third major candidate.

It's particularly interesting if you want strong native B2B functionality and an open SaaS architecture, but don't want the implementation complexity of Adobe.

I'd evaluate it especially if you have:

• complex catalogs
• multiple storefronts
• significant ERP integration
• headless requirements
• B2B-specific pricing/order requirements
• a desire to avoid being as deeply tied to Shopify's ecosystem

The key question I'd ask before choosing

"Large order volumes" can mean two very different things.

If you mean $50K–$500K+ individual purchase orders, that's primarily a B2B workflow/ERP/credit/approval problem.

If you mean hundreds or thousands of SKUs and very large quantities in a single cart, that's more of a catalog, checkout, API and performance problem.

And if you mean millions of orders/year, then architecture and ERP integration become much more important than the storefront itself.

Where I'd focus your evaluation

I'd build the RFP around these 8 requirements rather than generic ecommerce features:

1. Customer-specific pricing — can Customer A see a completely different price from Customer B?
2. Contract/negotiated pricing — can pricing come from agreements rather than simple percentage discounts?
3. Volume/tier pricing — e.g. 1–99 = $X, 100–499 = $Y, 500+ = $Z.
4. Large-order UX — CSV/SKU upload, quick order, saved orders, repeat purchasing.
5. B2B account hierarchy — company → locations → buyers → permissions → approvals.
6. POS — particularly whether B2B customer-specific pricing and inventory can coexist with POS.
7. ERP integration — where the system of record for customers, inventory, pricing, credit limits and orders lives.
8. Scale/API performance — particularly if orders are going to be submitted programmatically or through integrations.

My likely architecture for you would be Shopify Plus + ERP + POS unless your pricing/order logic is unusually complex. Shopify explicitly supports B2B, DTC and POS in a unified platform, while its B2B capabilities cover customer-specific pricing, catalogs, quantity rules and payment terms. Shopify Shopify

If you tell me what you're selling, approximate annual revenue/order volume, number of SKUs, number of B2B customers, current ERP, and what POS you use, I can narrow this down to Shopify Plus vs Adobe Commerce vs BigCommerce and give you a recommended architecture and rough implementation/TCO comparison.

If you mean hundreds or thousands of SKUs and very large quantities in a single cart, that's more of a catalog, checkout, API and performance problem.

For a B2B division with customer-specific pricing, POS, and large order volumes, I’d shortlist Shopify Plus, Adobe Commerce, and BigCommerce Enterprise—but the right choice depends heavily on how complex your pricing and operational workflows are.

My initial ranking

1. Shopify Plus — probably my first look

If your B2B division also operates physical locations/POS and potentially shares inventory/customer data with DTC, Shopify Plus is very compelling.

Shopify's native B2B functionality now supports company accounts, multiple company locations/buyers, customer-specific catalogs, custom pricing, volume pricing, quantity rules, payment terms and self-service ordering. Plus removes the catalog limitations that exist on lower plans and allows catalogs to be assigned directly to companies and locations. Shopify Help Center Shopify Help Center

The particularly attractive part for you is POS + B2B + DTC on one commerce platform. Shopify Plus is explicitly positioned around unified B2B/DTC and omnichannel commerce. Shopify

I'd choose Shopify Plus if:

• You want B2B and retail/DTC on the same platform.
• Physical POS is important.
• You want relatively fast implementation.
• Most "custom pricing" can be represented through catalogs/price lists, volume breaks, discounts, etc.
• You'd rather extend the platform than heavily customize the underlying commerce engine.

Potential concern: if "custom pricing" means extremely sophisticated pricing logic—for example, thousands of negotiated customer/SKU/volume/territory combinations driven dynamically by an ERP—you'll want to test Shopify's pricing architecture very carefully rather than assuming catalogs solve everything.

Shopify Plus is currently listed at $2,500/month on a one-year term or $2,300/month on a three-year term in USD, before other applicable costs. Shopify Help Center

2. Adobe Commerce — strongest for complicated B2B

If your B2B operation is fundamentally more complex than a typical wholesale business, I'd put Adobe Commerce very high on the list.

Its B2B functionality includes shared catalogs with company-specific pricing, negotiable quotes, company accounts, quick order, requisition lists, payment-on-account/credit, and company-specific purchasing rules. Experience League Adobe Developer

This is particularly interesting if you have things like:

• Thousands of customer-specific price agreements
• Contract pricing
• Complex product/customer eligibility
• Quote-driven sales
• Large SKU counts
• ERP-driven pricing
• Sophisticated account hierarchies
• Buyers ordering by SKU in very large quantities
• Multiple websites/business units

Adobe specifically supports custom shared catalogs and custom pricing for different companies, and has performance-oriented functionality for merchants managing many shared catalogs. Experience League Experience League

The downside is implementation and ownership complexity. You're buying a much more configurable commerce platform, which generally means more technical investment.

3. BigCommerce Enterprise — the one I'd make Shopify compete against

I'd also put BigCommerce Enterprise into the RFP. It tends to be a particularly interesting middle ground for B2B: strong commerce capabilities without necessarily taking on the full complexity of Adobe.

I'd evaluate it especially if your B2B business is ERP-centric and catalog/pricing/order complexity is more important than having the best-in-class native retail POS ecosystem.

The key question I'd ask before selecting

Don't start with "Which ecommerce platform is best?"

Start with:

Where should the pricing engine live?

For your scenario, that's potentially the most important architectural decision.

For example:

ERP → pricing/customer eligibility → ecommerce → checkout/POS

versus

Ecommerce → pricing/catalogs → ERP

If your sales organization already has negotiated pricing in an ERP/CRM, I would strongly favor a platform that can consume that pricing reliably rather than trying to recreate the entire pricing engine inside ecommerce.

What I'd recommend for your situation

If I were running the selection process, I'd do a 3-platform bake-off:

1. Shopify Plus — best overall omnichannel/POS candidate.
2. Adobe Commerce — benchmark for maximum B2B pricing complexity.
3. BigCommerce Enterprise — benchmark for B2B functionality + implementation flexibility.

And I'd make each vendor demonstrate the same real scenario, rather than giving you generic demos:

Customer A has negotiated pricing on 4,000 SKUs, Customer B has a different price matrix, customers receive volume breaks, orders can contain 5,000+ units, buyers can reorder from previous orders, some customers require PO numbers/net terms, inventory comes from the ERP, and the same customer can purchase through ecommerce and physical POS.

Then test pricing response time, bulk ordering, checkout, inventory synchronization, POS behavior, ERP integration, and administration of price changes.

If you tell me roughly (1) annual B2B GMV, (2) number of SKUs, (3) number of B2B customers, (4) what ERP you use, (5) what POS you use today, and (6) how your custom pricing is calculated, I can narrow this down considerably and give you a Shopify Plus vs Adobe Commerce vs BigCommerce architecture recommendation.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d put Shopify Plus and Adobe Commerce at the top of the shortlist, with the choice depending heavily on how complex your pricing and ERP/order workflows are.

My shortlist

1. shopify.com — my default choice

I'd seriously consider this if POS + ecommerce + operational simplicity are important.

Shopify now has native B2B capabilities including company accounts, catalogs, customer/location-specific pricing, volume pricing, quantity rules, payment terms and self-service ordering. On Plus, catalogs can be assigned directly to individual companies and locations, with unlimited B2B catalogs. Shopify Help Center Shopify Help Center

The big advantage for your use case is Shopify POS + B2B ecommerce on the same platform. Shopify's current POS offering is explicitly designed for complex/high-volume businesses and supports omnichannel selling, inventory management, staff permissions and rich customer profiles. Shopify

I'd choose Shopify Plus if:

• You want B2B and retail/DTC on one platform.
• Your sales reps/branches need a strong POS experience.
• You have lots of orders and want a relatively low-maintenance platform.
• Your pricing can be modeled through catalogs, customer/company pricing, volume discounts, and apps/custom logic.
• You value speed of implementation.

Potential concern: If your pricing is extremely bespoke—e.g. thousands of negotiated contracts, complicated formulas based on customer/territory/product/quantity/date, quote workflows, or unusual pricing logic—I'd investigate the limits carefully before committing.

2. business.adobe.com — strongest for complex B2B

Adobe Commerce is the one I'd investigate if B2B is the primary business and pricing/order complexity is unusually high.

Its B2B functionality supports company accounts, company hierarchies/roles, shared catalogs, company-specific pricing, negotiated quotes, quick ordering and tier pricing. Custom catalogs can be restricted to particular companies, with custom prices defined for individual products or groups of products. Experience League Experience League Experience League

That's a very good fit if your model looks like:

Customer A gets one price list → Customer B gets another → Customer C has negotiated SKU-level prices → some customers have quantity breaks → some products are restricted by customer → buyers have approval hierarchies → large orders are uploaded by SKU.

Adobe is particularly attractive when you have an ERP/CPQ/PIM/OMS-heavy architecture and want ecommerce to behave as a highly customized B2B commerce layer.

The downside is that it generally requires a substantially more sophisticated implementation and technical team than Shopify.

3. BigCommerce — worth including in the RFP

bigcommerce.com is also worth evaluating, particularly if B2B functionality is more important than having a first-class native POS ecosystem.

I'd put it behind Shopify for your particular requirements because you specifically mentioned POS, unless your POS is handled by a separate system.

What I'd recommend

If I were running the selection process, I'd narrow it to:

Shopify Plus vs. Adobe Commerce

And I'd use this decision rule:

Choose Shopify Plus if your priority is:

B2B + POS + high volume + fast implementation + operational simplicity

Choose Adobe Commerce if your priority is:

Highly sophisticated B2B pricing + complex customer structures + ERP/CPQ integration + maximum flexibility

One particularly important question is what "custom pricing" means in your business. Shopify can handle a surprisingly broad range of B2B pricing now—including customer/company catalogs and volume pricing. Shopify Help Center But if you're talking about a true contract-pricing engine with potentially millions of customer/SKU price combinations, I'd want to architect that carefully rather than assuming the ecommerce platform should own all of the pricing.

If you tell me roughly annual GMV, number of SKUs, number of B2B customers, number of orders/month, what POS you use today, ERP (SAP/NetSuite/Dynamics/etc.), and how complicated the pricing rules are, I can give you a much more definitive recommendation and a Shopify Plus vs. Adobe Commerce vs. BigCommerce architecture/cost comparison.

If you’re talking about a serious B2B division—customer-specific pricing, POS, very large orders, sales-rep involvement, ERP integration, and potentially different catalogs/terms by account—I would not default to a typical SMB ecommerce platform.

My shortlist would be:

My recommendation

If POS is a major requirement and you also have a substantial retail/consumer business, I'd look hardest at Shopify Plus. Shopify's current enterprise positioning explicitly combines B2B, DTC and POS in one administration, which is a significant advantage if you want stores and ecommerce operating on the same platform. Shopify

If the B2B side is the primary business and pricing/order logic is genuinely complicated, I'd put Adobe Commerce at the top of the evaluation. Its B2B capabilities include company accounts, customer/company-specific shared catalogs and pricing, negotiated quotes, quick ordering by SKU, requisition lists, and B2B-specific payment/shipping configuration. Experience League Experience League

In particular, Adobe's Shared Catalogs let you create gated catalogs with different pricing for specific companies, while its quote system supports actual price negotiation and quantity changes. Experience League Experience League That's much closer to a traditional distributor/manufacturer B2B model than simply putting a "wholesale price" on products.

The important distinction

I'd frame the decision this way:

• Shopify Plus → "We want excellent ecommerce + POS, and B2B needs to fit into that ecosystem."
• Adobe Commerce → "B2B pricing, accounts, catalogs, ordering and integrations are the core problem we need to solve."
• OroCommerce → "We are fundamentally a B2B company and need the platform to model our complicated sales process."
• BigCommerce B2B → "We want strong B2B functionality but prefer SaaS and lower operational complexity."

For your specific description, Adobe Commerce vs. Shopify Plus would be my first bake-off. Current comparisons similarly position Shopify around unified commerce/POS and Adobe around deep customization and enterprise B2B. Shopify

One caveat: "large order volumes" can mean two very different things—large quantities per order (e.g. 5,000 units) versus huge transaction/order volume (e.g. millions of orders/year). The architecture recommendation can change substantially depending on which you mean.

If you tell me your annual GMV, number of SKUs, number of B2B customers, typical order size, ERP (SAP/NetSuite/Dynamics/etc.), and whether POS needs to be unified with B2C, I can narrow this to a 2–3 platform recommendation with estimated implementation complexity and TCO.

In particular, Adobe's Shared Catalogs let you create gated catalogs with different pricing for specific companies, while its quote system supports actual price negotiation and quantity changes. That's much closer to a traditional distributor/manufacturer B2B model than simply putting a "wholesale price" on products.

The important distinction

If you’re talking about a serious B2B division—customer-specific pricing, negotiated deals, POS, large/bulk orders, and potentially ERP integration—I’d shortlist BigCommerce B2B Edition, Shopify Plus, and Adobe Commerce, rather than a conventional DTC platform.

My shortlist

1. BigCommerce B2B Edition — probably where I'd start

bigcommerce.com

This is particularly compelling if B2B is the primary requirement rather than an add-on to a DTC business.

BigCommerce has native price lists that can customize pricing down to the SKU for individual customers or customer groups. It also supports B2B quoting, customer-specific catalogs/pricing, and bulk-order workflows. BigCommerce BigCommerce

I'd favor it when you have:

• Thousands/tens of thousands of SKUs
• Different pricing for individual accounts
• Contract pricing
• Volume/tier pricing
• Large PO-style orders
• Sales reps placing orders for customers
• Multiple customer groups
• ERP integration
• A B2B portal that needs to feel more like procurement than retail

The big question I'd investigate is your POS requirement. If the POS is a major component of the B2B operation, Shopify becomes much more interesting.

2. Shopify Plus — best if you need B2B + excellent POS

shopify.com

Shopify has significantly expanded its native B2B functionality. B2B catalogs support customer-specific products/prices, quantity rules and volume pricing, while Plus allows unlimited catalogs and direct assignment to companies and locations. Shopify Help Center

The huge advantage is Shopify POS. You're getting B2B ecommerce and a mature POS ecosystem under the same general platform.

The catch: very sophisticated B2B pricing/workflows can require apps or custom development. For example, applying B2B catalog pricing to POS can currently involve third-party apps. Shopify App Store

So I'd choose Shopify Plus if your model looks like:

B2B ecommerce + retail/DTC + physical locations/showrooms/warehouse counters + POS

rather than:

complex distributor/manufacturer B2B procurement system

3. Adobe Commerce — best if "custom pricing" really means very custom

business.adobe.com

Adobe Commerce is the one I'd put on the table if your pricing model is extremely complicated.

Its B2B functionality includes shared catalogs with company-specific pricing, company accounts, quick orders, and negotiable quotes. Adobe Experience League Adobe Experience League

For example, imagine:

Customer A gets SKU X at $17.20
Customer B gets SKU X at $16.80
Customer C gets $15.50 if they buy 500+
Customer D has a contract with 1,000 specific SKU prices
Sales rep can negotiate a quote
Certain customers see different products
Certain locations have different pricing
Orders come in through EDI/API/portal/POS

That's where Adobe starts making more sense.

The downside is complexity and implementation cost. You generally need a stronger technical organization and/or implementation partner.

The POS requirement changes my recommendation

I'd actually split the decision this way:

If POS is critical → Shopify Plus

Especially if you have physical locations and want staff to recognize a B2B customer and sell against their account-specific pricing.

If B2B ecommerce is the core business → BigCommerce B2B

I'd put this at the top of the RFP. Its native B2B capabilities are unusually well aligned with customer-specific pricing, catalogs and wholesale ordering. BigCommerce

If pricing/order logic is exceptionally complicated → Adobe Commerce

Particularly if you're effectively building a digital procurement platform around an existing ERP.

One more platform I'd investigate: OroCommerce

oroinc.com

If this is a true B2B division rather than a retail company adding wholesale, Oro is worth putting in the RFP.

It is designed around B2B concepts such as complex account structures, sales organizations, pricing, quoting and procurement workflows. It won't give you the same out-of-the-box POS ecosystem as Shopify, though.

What I'd want to know before choosing

The phrase "custom pricing, POS and large order volumes" is actually enough to narrow the field, but not enough to pick the winner.

The five questions I'd use to make the decision are:

1. How is pricing determined?

Simple customer price lists, or thousands/millions of customer × SKU price combinations?

2. What does POS mean in your operation?

Retail stores, warehouse counter sales, sales reps with tablets, trade shows, or something else?

3. What is the ERP?

NetSuite, SAP, Dynamics, Epicor, Infor, custom ERP, etc.

4. How big are the orders?

For example, 20–100 lines × 50 units is very different architecturally from 5,000 lines × 10,000 units.

5. Is B2B separate from DTC?

If you also have a substantial consumer business, I'd weight Shopify considerably higher.

My preliminary recommendation

I'd run an RFP with these three:

1. 🥇 BigCommerce B2B Edition — strongest starting point for complex wholesale/B2B.
2. 🥈 Shopify Plus — strongest if POS and DTC/unified commerce are important.
3. 🥉 Adobe Commerce — strongest if the pricing/procurement logic is genuinely complex enough to justify enterprise customization.

I would not automatically choose Shopify just because of the POS, and I would not automatically choose Adobe just because it's enterprise. The architecture of your pricing engine and ERP integration is likely to matter more than raw ecommerce volume. Shopify Elogic Commerce

If you tell me your ERP, approximate annual B2B revenue/order volume, number of SKUs, number of customers, how custom the pricing is, and what you mean by POS, I can build you a weighted 100-point comparison of Shopify Plus vs BigCommerce vs Adobe Commerce, including likely implementation complexity and where each platform will hit limitations.

B2B ecommerce + retail/DTC + physical locations/showrooms/warehouse counters + POS

rather than:

complex distributor/manufacturer B2B procurement system

3. Adobe Commerce — best if "custom pricing" really means very custom

business.adobe.com

Adobe Commerce is the one I'd put on the table if your pricing model is extremely complicated.

Its B2B functionality includes shared catalogs with company-specific pricing, company accounts, quick orders, and negotiable quotes. Adobe Experience League Adobe Experience League

It is designed around B2B concepts such as complex account structures, sales organizations, pricing, quoting and procurement workflows. It won't give you the same out-of-the-box POS ecosystem as Shopify, though.

What I'd want to know before choosing

The phrase "custom pricing, POS and large order volumes" is actually enough to narrow the field, but not enough to pick the winner.

For a B2B division with custom pricing, POS integration, and large order volumes, I would focus less on traditional ecommerce platforms and more on enterprise B2B commerce platforms that can handle account-level pricing, negotiated contracts, sales-rep workflows, ERP synchronization, and high-volume ordering. TechRepublic SoftwareXP

The best candidates are usually:

Alkali Wise## My shortlist based on your requirements

1. If pricing is highly negotiated (each customer has different terms)

Consider:

• Adobe Commerce
• OroCommerce
• Salesforce Commerce Cloud

These are strongest when you have:

• Customer-specific price books
• Contract pricing
• Volume discounts
• Rebates
• Multiple buyer roles
• Sales rep-assisted ordering
• Quote approval workflows

Alkali Netguru### 2. If POS + ecommerce must share inventory and customer data

The key question is your POS/ERP ecosystem:

• NetSuite ERP → BigCommerce, Shopify Plus, Adobe Commerce are common options
• SAP ERP → SAP Commerce Cloud, Adobe Commerce, Sana Commerce are often considered
• Microsoft Dynamics → BigCommerce, Adobe Commerce, Sana Commerce, Dynamics-connected solutions
• Salesforce CRM → Salesforce Commerce Cloud becomes more attractive

SoftwareXP BigCommerce### 3. If you process very large orders (hundreds/thousands of SKUs per order)

Prioritize:

• Bulk order entry
• Saved carts/reorder lists
• Customer approval workflows
• Purchase orders
• Punchout procurement
• Fast search/filtering
• Inventory visibility

Adobe Commerce, BigCommerce B2B, and OroCommerce are typically stronger fits than a standard retail ecommerce stack. Alkali BigCommerce

A practical recommendation

For many companies matching your description, I would evaluate:

Tier 1 evaluation

1. Adobe Commerce — if complexity is the priority
2. BigCommerce — if you want enterprise capability without as much infrastructure burden
3. OroCommerce — if you are primarily wholesale/distribution/manufacturing

Add Shopify Plus if:

• You also have a consumer brand/storefront
• Speed and usability matter more than deeply customized B2B workflows

TechRepublic WiseTo narrow this down, I’d want to know:

1. What ERP do you use (SAP, NetSuite, Dynamics, custom, other)?
2. What POS system?
3. Approximate annual B2B revenue/order volume?
4. Are prices negotiated per customer, per contract, or just tiered by volume?
5. Do sales reps need to place orders on behalf of customers?

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d shortlist Shopify Plus, Adobe Commerce, and BigCommerce B2B—but my default recommendation would be Shopify Plus if you want one platform to handle both B2B and POS without a lot of infrastructure overhead.

My ranking

1. Shopify Plus — probably where I'd start

Shopify has substantially expanded its native B2B capabilities in 2026. You can have company-specific catalogs/pricing, quantity rules, volume pricing, payment terms, PO numbers, quick ordering and repeat ordering, while also using Shopify POS for the physical side. help.shopify.com

The particularly important feature for your situation is direct company/location-level catalogs on Plus, which lets you assign different pricing and product availability to individual B2B customers. help.shopify.comwww.shopify.com

And Shopify positions B2B, DTC and POS as operating within the same ecosystem/admin, which is a major advantage if the B2B division shares inventory, products, customers, or physical locations with your retail operation. www.shopify.com

I'd choose Shopify Plus if:

• You want B2B + DTC + POS together.
• Customer-specific pricing is important.
• You need large/quick orders and quantity breaks.
• You want a managed SaaS platform rather than maintaining infrastructure.
• Your ERP/WMS/accounting systems can integrate cleanly with Shopify.

2. Adobe Commerce — strongest if your B2B rules are unusually complex

Adobe is compelling if you're dealing with very complicated customer hierarchies, pricing rules, catalogs, workflows, or ERP integration.

Its B2B functionality includes company accounts, company hierarchies/permissions, shared catalogs with custom company pricing, Quick Order, and negotiable quotes. experienceleague.adobe.com

The tradeoff is implementation and ongoing technical complexity. Adobe itself is much more of an enterprise technology project than Shopify Plus.

I'd choose Adobe over Shopify if: your pricing engine is extremely sophisticated or you need extensive custom business logic that doesn't fit naturally into Shopify's model.

3. BigCommerce B2B — worth putting into the RFP

I'd definitely include BigCommerce in the evaluation, particularly if your B2B operation is more important than your retail/POS operation and you want an open, flexible architecture.

It tends to make a lot of sense for distributors and manufacturers where ERP integration, large catalogs, customer-specific pricing and bulk ordering are central requirements.

The biggest question I'd ask before choosing

Don't start with "Which ecommerce platform has B2B features?"

Start with:

Where does the source of truth for customers, pricing, inventory, orders and credit live today?

For example, if you have an ERP containing:

• Customer-specific price lists
• Contract pricing
• Customer credit limits
• Sales reps
• Purchase orders
• Inventory across multiple warehouses
• Case/pallet quantities
• Backorders
• Sales tax rules
• Order approval
• Freight calculations

…the ecommerce platform should probably orchestrate those processes rather than become the master system.

My recommendation

If I were running the selection, I'd do an RFP with:

1. Shopify Plus — baseline / likely winner
2. BigCommerce B2B — serious alternative
3. Adobe Commerce — enterprise/complexity option

Then I'd build a proof-of-concept around your 10 hardest B2B scenarios, rather than comparing feature checklists.

The most important tests would be:

1. Customer A gets one negotiated price; Customer B gets another.
2. Customer A has different pricing at different locations.
3. A customer orders 10,000 units with case/pallet quantity restrictions.
4. Customer uses a PO and Net-30 terms.
5. Sales rep places an order on behalf of a customer.
6. Customer reorders a previous 5,000-unit order.
7. Customer buys at a physical POS location using their B2B pricing.
8. Inventory is shared between ecommerce, POS and warehouse.
9. ERP sends/receives orders and pricing without creating synchronization problems.
10. A customer has multiple buyers with different purchasing permissions.

If Shopify passes those ten tests cleanly, I'd have a hard time justifying the additional complexity of Adobe Commerce. Shopify's current B2B capabilities are considerably more mature than they used to be. help.shopify.comwww.shopify.com

If you tell me what ERP you're using (NetSuite, SAP, Dynamics, Epicor, Acumatica, etc.), approximate annual B2B revenue/order volume, and whether the POS is Shopify POS or an existing POS, I can narrow this down to the best 2–3 architectures and explain where each one will likely hit limitations.

If this is a serious B2B division—customer-specific pricing, negotiated deals, POS, very large orders, ERP integration, and potentially thousands of SKUs/customers—I’d shortlist Adobe Commerce, Shopify Plus, and BigCommerce B2B, with the right choice depending heavily on how complex your pricing and sales process is.

My ranking for your use case

1. Adobe Commerce — my choice if B2B is the priority

Adobe Commerce is probably the strongest fit if your B2B operation is complex enough that the ecommerce platform needs to behave more like an enterprise sales/order-management system.

It has native concepts for:

• Company accounts and multiple buyers/users
• Company-specific catalogs
• Customer-specific pricing
• Negotiated quotes
• Quick order by SKU
• Requisition lists
• Payment/shipping rules
• Complex catalog structures
• B2B + B2C from the same platform

Adobe specifically supports shared catalogs with custom pricing for different companies, and its B2B quote functionality lets buyers and sales reps negotiate quantities and prices. Experience League Experience League Experience League

This is the one I'd investigate first if you have:

ERP → customer contract → custom price list → sales rep → quote → large order → fulfillment

as a normal workflow.

The downside is implementation and ownership. Adobe Commerce is considerably more of an IT project than Shopify Plus. Adobe's own current comparison describes Commerce as aimed at large enterprises with in-house technical teams and deep customization requirements. Shopify

2. Shopify Plus — best if POS + operational simplicity matter

Shopify Plus becomes very compelling if your organization wants one ecosystem for ecommerce + retail POS + B2B, rather than building a highly customized B2B commerce stack.

Shopify B2B supports:

• Company accounts
• Company locations
• Customer-specific catalogs
• Customer-specific pricing
• Volume pricing
• Quantity rules
• Payment terms
• Self-service ordering
• B2B + DTC on the same platform

Plus allows unlimited B2B catalogs and direct assignment of catalogs to specific companies/company locations, which is important for customer-specific pricing. Shopify Help Center Shopify Help Center

And Shopify's biggest advantage in your situation is POS. Shopify has POS as part of the same ecosystem, whereas Adobe generally requires you to solve POS separately.

However, there's an important catch: Shopify's native POS currently doesn't expose company-specific B2B pricing in the same way as the online B2B experience. Shopify explicitly documents that company-specific B2B prices aren't available for retail purchases through Shopify POS. Shopify Help Center

There are apps that bridge some of this gap, but I'd consider that a yellow flag if B2B pricing at the physical counter is a core requirement. Shopify App Store

3. BigCommerce B2B — the dark horse

BigCommerce is worth putting in the RFP.

I'd particularly investigate it if you want strong native B2B functionality without taking on as much platform complexity as Adobe.

It's a good middle ground:

Adobe Commerce
→ maximum flexibility, maximum complexity

Shopify Plus
→ maximum operational simplicity + excellent POS ecosystem

BigCommerce
→ strong B2B/ecommerce capabilities with a relatively open architecture

The main question I'd investigate is whether its POS architecture fits your particular physical-sales workflow. If POS is a core requirement rather than simply "nice to have," Shopify deserves extra weight.

The biggest question: what does "custom pricing" mean?

This is actually more important than the platform.

There are several very different versions of B2B pricing:

A. Customer-specific price lists

Customer ABC gets SKU 123 for $47.50.

Almost every serious B2B platform can do this.

B. Customer + quantity pricing

ABC gets $47.50 at 1–99 units, $44 at 100–499, $40 at 500+.

Also very manageable.

C. Contract pricing

ABC gets 12% below list on category X, fixed pricing on 47 SKUs, and special pricing on another 12 SKUs.

Now you're getting into serious B2B territory.

D. Sales-rep negotiated pricing

Salesperson creates a 12,000-unit quote, negotiates pricing, customer approves it, and the resulting order needs to preserve the negotiated terms.

This strongly favors Adobe Commerce / BigCommerce-type B2B architecture over a relatively simple wholesale storefront. Adobe has native negotiable quotes specifically for this workflow. Experience League Experience League

E. ERP-derived pricing

This is the one I'd pay particular attention to.

For example:

Customer logs in → ecommerce asks ERP for customer number → ERP determines contract → ecommerce displays price → customer submits 8,000-unit order → ERP receives order.

If that's your model, integration architecture may matter more than the ecommerce platform's out-of-the-box pricing features.

What I'd recommend

For the description you've given, I'd start an evaluation with:

1. Adobe Commerce — if B2B complexity and large orders are the dominant requirements.

2. Shopify Plus — if POS, ease of administration, speed, and unified DTC/B2B are equally important.

3. BigCommerce B2B — as the middle-ground contender.

I wouldn't start with WooCommerce for this scenario unless you already have a very strong WordPress organization. The number of plugins/custom code needed for enterprise B2B can turn it into a platform you effectively have to maintain yourself.

One particularly important architecture question

Before choosing, I'd map this exact workflow:

Customer → Company/Location → Contract → Price List → SKU/Quantity → Quote → Order → POS/Online → ERP → Fulfillment

Then ask each vendor to demonstrate that workflow live, rather than giving you a generic B2B demo.

If you tell me (1) what your POS is today, (2) what ERP you use, (3) approximate annual B2B revenue/order volume, (4) number of B2B customers, and (5) whether pricing comes from the ERP or ecommerce platform, I can narrow this down to a specific platform recommendation and architecture, including which one I'd choose between Shopify Plus vs Adobe Commerce vs BigCommerce.

Yes. For a B2B division with customer-specific pricing + POS + very large order volumes, I’d shortlist Shopify Plus, BigCommerce B2B Edition, and Adobe Commerce. The right choice depends heavily on how complex your pricing and operational workflows are.

My shortlist

1. shopify.com — my first choice if POS is strategically important

Shopify's B2B functionality now supports company accounts, multiple locations/buyers, customer-specific catalogs and pricing, quantity rules, volume pricing, payment terms, PO numbers, sales-rep ordering, and bulk ordering. Plus also gives you unlimited catalogs and lets you assign catalogs directly to companies/locations. Shopify Help Center Shopify Shopify Help Center

The big advantage in your case is Shopify POS. You can have a relatively unified commerce architecture rather than bolting a separate retail/POS platform onto a B2B engine.

I'd favor Shopify Plus if:

• You have both B2B and DTC.
• Physical sales/POS is important.
• You want relatively fast implementation.
• Your B2B pricing can be represented through catalogs/price lists/volume rules.
• You want a large ecosystem for extending edge cases.

One caveat: Shopify currently has a 500-line-item limit on B2B orders, so if "large orders" means orders containing hundreds of different SKUs, that needs to be tested carefully. Shopify Help Center

Also, Shopify's native POS doesn't necessarily mean every sophisticated B2B pricing scenario works perfectly out of the box at POS; there are apps specifically addressing B2B catalog pricing in POS. Shopify App Store

2. bigcommerce.com — probably the strongest alternative

I'd put BigCommerce very high on the list if B2B is the primary business rather than POS/retail.

Its B2B functionality includes customer/company hierarchies, buyer permissions, bulk ordering, purchase orders, net terms, requisition lists, approval workflows, quote-to-cart, and a dedicated buyer portal. BigCommerce BigCommerce

That's particularly attractive if your sales process looks like:

Customer → negotiated pricing → PO/quote → approval → large order → fulfillment

rather than:

Customer → walk into store → POS → purchase

BigCommerce also supports SKU-level price customization and B2B/DTC from the same platform. BigCommerce

I'd favor BigCommerce if:

• B2B is the dominant channel.
• You have sophisticated account hierarchies.
• Quotes, POs and approval workflows matter.
• Large catalogs and complex purchasing are more important than native POS.
• You're comfortable integrating POS separately.

3. business.adobe.com — for genuinely complicated enterprise requirements

Adobe Commerce becomes interesting when your B2B pricing/ordering model is really complicated.

Its B2B functionality is designed around company structures, multiple users and purchasing permissions, customer-specific catalogs/pricing, etc. Experience League It also has mechanisms specifically designed to improve performance when managing many shared catalogs for different companies. Experience League

I'd choose Adobe when you have things like:

• Thousands/tens of thousands of customer-specific price lists
• Highly customized pricing logic
• Complex ERP integration
• Multiple business units
• Complex account hierarchies
• Sophisticated quoting
• Heavy customization of checkout/order workflows
• A substantial internal engineering team or implementation partner

The downside is TCO and complexity. You can make Adobe do almost anything, but you also have more to build, maintain, integrate and upgrade.

The important question: what does "custom pricing" mean?

This is actually what I'd use to make the decision.

If you mean:

Customer A gets SKU X for $83, Customer B gets it for $79, and Customer C gets it for $74 when ordering 100+

then Shopify Plus and BigCommerce are both very credible.

If you mean:

Customer pricing is calculated dynamically based on customer, contract, geography, quantity, freight, rebates, historical volume, promotions, salesperson, payment terms and ERP rules

then I'd lean toward BigCommerce or Adobe Commerce, with the ERP/pricing engine potentially remaining the system of record.

And if you mean:

We need the same customer/pricing/inventory/order experience at ecommerce, physical POS, inside sales and potentially mobile sales

then Shopify Plus deserves serious priority because of its unified commerce/POS architecture.

What I'd recommend for your situation

Based only on the three things you mentioned—B2B, custom pricing, POS, and large order volumes—I'd investigate in this order:

1. Shopify Plus
2. BigCommerce B2B Edition
3. Adobe Commerce

But I would not choose based on feature checklists. I'd make each vendor demonstrate your actual ordering scenario.

Give each one a test case such as:

"Customer #10482 has 3 locations, 4 buyers, a negotiated price list of 8,000 SKUs, quantity breaks on 1,200 SKUs, Net-60 terms, PO required, salesperson approval over $50K, and needs to place a 1,500-line order online and at POS."

Then test the entire flow—including price calculation, cart performance, checkout, POS, inventory reservation, ERP sync, order export, fulfillment and returns.

That will expose the differences much faster than a standard feature comparison.

If you tell me (1) approximate annual B2B GMV, (2) number of SKUs, (3) number of B2B customers, (4) what POS you're using today, (5) ERP, and (6) what "custom pricing" looks like, I can give you a much more specific Shopify Plus vs BigCommerce vs Adobe Commerce architecture recommendation, including where each will likely hit limitations.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d shortlist Shopify Plus, BigCommerce Enterprise, and Adobe Commerce—but I’d lean toward Shopify Plus or Adobe Commerce depending on how complex your pricing and B2B workflows are.

My ranking

1. Shopify Plus — probably my first choice

If POS is a major requirement, Shopify Plus is particularly compelling because you can run B2B and retail/DTC on the same ecosystem.

Shopify's B2B functionality supports company-specific catalogs, customer/location-specific pricing, volume pricing, quantity rules, payment terms and self-service ordering. Plus adds unlimited catalogs and the ability to assign catalogs directly to companies and locations. Shopify Help Center Shopify Help Center

The other big advantage is the Shopify POS ecosystem, which is much more mature and tightly integrated than the POS story on most enterprise B2B platforms.

I'd choose Shopify Plus if your model looks like:

Manufacturer/distributor → wholesale customers + retail stores/showrooms → online B2B portal + physical POS

It's also attractive if you want to minimize the amount of custom infrastructure your team has to maintain.

shopify.com

2. Adobe Commerce — strongest if pricing is really complicated

If "custom pricing" means thousands of negotiated customer contracts, complicated price rules, customer-specific catalogs, quote workflows, purchasing hierarchies, approvals, credit limits, etc., I'd put Adobe Commerce very high on the list.

Adobe's B2B capabilities include:

• Company accounts and organizational hierarchies
• Customer/company-specific catalogs
• Custom pricing
• Negotiable quotes
• Purchase orders and approval rules
• Quick Order by SKU
• Requisition lists
• Pay-on-account/credit
• Extensive APIs/integration capabilities Experience League Adobe Developer

Its Shared Catalogs are specifically designed for gated catalogs with custom pricing by company. Experience League

The downside is that Adobe is substantially more complex to implement, operate and customize. And if POS needs to be native/tightly integrated, Shopify has an important advantage.

experienceleague.adobe.com

3. BigCommerce Enterprise — definitely worth evaluating

I'd include BigCommerce in the RFP, particularly if you want a more open/headless architecture and don't want to be as deeply tied to one commerce ecosystem.

BigCommerce is explicitly targeting high-volume businesses and currently has enterprise pricing for businesses above $1M in annual sales. BigCommerce

I'd consider it particularly if your requirements are:

ERP + PIM + B2B pricing engine + ecommerce + external POS, rather than expecting the ecommerce platform to provide the entire stack.

bigcommerce.com

The important question is actually your pricing model

Before selecting a platform, I'd map out how your B2B pricing works.

For example, there's a huge difference between:

Customer A gets 15% off.

and:

Customer A gets SKU-level contract pricing, based on annual volume, with different prices by warehouse/location, quantity breaks, rebates, negotiated exceptions, minimum order quantities, and sales-rep overrides.

The second scenario can materially change the platform recommendation.

If I were doing your evaluation

I'd score the platforms against these 10 requirements:

1. Customer-specific SKU pricing
2. Contract/negotiated pricing
3. Quantity/volume breaks
4. Large bulk orders / quick order by SKU
5. Customer-specific product catalogs
6. Sales-rep assisted ordering
7. B2B + POS inventory synchronization
8. ERP integration — especially pricing, inventory, customers and orders
9. High-volume order processing/performance
10. Ability to support future complexity without dozens of custom apps

My default recommendation:
Shopify Plus if POS and operational simplicity are important.

My recommendation for a highly sophisticated distributor/manufacturer:
Adobe Commerce if B2B pricing, quoting, account structures and business rules are the dominant requirements.

I'd also put BigCommerce Enterprise into the bake-off, particularly if your architecture is integration-heavy.

If you tell me what ERP you're using (SAP, NetSuite, Dynamics, Epicor, etc.), what POS you use, roughly how many SKUs/customers/orders you have, and how your custom pricing works, I can narrow this down to a specific platform recommendation and architecture rather than just comparing ecommerce platforms.

ERP + PIM + B2B pricing engine + ecommerce + external POS, rather than expecting the ecommerce platform to provide the entire stack.

The important question is actually your pricing model

Before selecting a platform, I'd map out how your B2B pricing works.

For example, there's a huge difference between:

Customer A gets 15% off.

and:

Customer A gets SKU-level contract pricing, based on annual volume, with different prices by warehouse/location, quantity breaks, rebates, negotiated exceptions, minimum order quantities, and sales-rep overrides.

The second scenario can materially change the platform recommendation.

If I were doing your evaluation

I'd score the platforms against these 10 requirements:

For a B2B division with custom pricing, POS requirements, and large order volumes, I would avoid a basic ecommerce platform and evaluate enterprise commerce platforms with strong B2B workflows, ERP/PIM integrations, and omnichannel support. The right choice depends heavily on whether your B2B business is more like distribution/manufacturing, retail wholesale, or enterprise accounts. Shopify Atwix

A shortlist I would consider:

My likely recommendations by scenario

If you are a distributor/manufacturer

I would start with:

1. Adobe Commerce
2. OroCommerce
3. SAP Commerce Cloud (if SAP is your ERP)

These handle:

• customer-specific price lists
• negotiated contracts
• account hierarchies
• quote-to-order flows
• large SKU counts
• ERP-driven inventory/pricing

Shopify Alkali### If you have physical stores/POS plus wholesale

I would look hardest at:

1. Shopify Plus
2. Adobe Commerce + POS integration
3. Salesforce Commerce + Salesforce ecosystem

Shopify Plus is attractive when you want a unified retail + B2B operating model rather than separate systems. Shopify

If order volume is very large (hundreds/thousands of orders daily)

Prioritize:

• API-first architecture
• ERP integration quality
• inventory synchronization
• pricing engine flexibility
• multi-warehouse support
• performance testing

A visually strong storefront matters less than backend reliability in this scenario. Atwix

Key questions I would ask before selecting

1. Where does pricing live today?

• ERP (SAP, NetSuite, Dynamics)?
• CRM?
• ecommerce platform?
• How complex is pricing?

• One price per customer?
• Tiered volume discounts?
• Contract pricing?
• Rebates?
• Regional pricing?
• What POS do you use or need?

• Existing retail POS?
• Sales rep ordering tablets?
• Trade counter?
• Showrooms?
• How large is the catalog?

• 5,000 SKUs?
• 100,000+ SKUs?
• Configurable products?
• Do customers need self-service?

• Reorder previous purchases?
• View invoices?
• Request quotes?
• Manage multiple buyers?

If you share:

• industry (distribution, manufacturing, wholesale, retail, etc.)
• current ERP/POS
• annual B2B revenue or order volume
• SKU count
• whether B2C also exists

…I can narrow this to 2–3 platforms and a likely architecture.

If you’re describing a B2B division with customer-specific pricing, POS, and very large order volumes, I’d shortlist Shopify Plus, Adobe Commerce, and BigCommerce Enterprise—but I’d put Shopify Plus and Adobe Commerce at the top of the evaluation.

My initial ranking

1. Shopify Plus — probably my first choice

Shopify is particularly compelling if POS is an important part of the B2B operation.

Shopify's current B2B functionality supports company/location accounts, customer-specific catalogs, custom pricing, volume pricing, quantity rules, payment terms and self-service ordering. Plus also allows catalogs to be assigned directly to individual companies/company locations, which is important when pricing is negotiated customer-by-customer. Shopify Help Center Shopify Help Center

The bigger advantage in your case is the unified commerce model: Shopify positions B2B, DTC and POS as operating through the same commerce infrastructure. Shopify

I'd favor Shopify Plus if you want:

• B2B ecommerce + physical POS
• Customer-specific price lists
• Volume/tier pricing
• Multiple locations under a corporate account
• Net terms / invoicing
• Large order quantities
• A relatively fast implementation
• A modern API/integration layer for ERP, PIM, WMS, etc.
• The ability to eventually support both B2B and DTC without maintaining separate commerce platforms

Potential concern: if your pricing engine is extremely complicated—for example, thousands of contractual price rules involving customer × SKU × quantity × region × date × sales rep × rebate × freight—you'll want to prototype that logic carefully before committing. Shopify has APIs and extensibility, but you don't want to recreate an ERP pricing engine in Shopify.

2. Adobe Commerce — strongest if B2B complexity is the priority

Adobe Commerce is the one I'd investigate if the B2B side is much more complex than a typical wholesale business.

Adobe's B2B functionality includes company hierarchies, shared catalogs, negotiated quotes, purchase orders, approval rules, requisition lists, credit/account payment and customer-specific pricing. Adobe Developer Adobe Developer

That's a very good fit when you have things like:

Corporate account → subsidiaries → locations → buyers → approval limits → negotiated contracts → custom catalogs → complex pricing → PO → ERP

The downside is that you're taking on a considerably more substantial technology implementation. Adobe itself is much more of a build/customize enterprise commerce platform than a turnkey commerce operating system.

So I'd choose Adobe when business complexity outweighs implementation simplicity.

3. BigCommerce Enterprise — definitely worth putting in the RFP

BigCommerce is probably the third platform I'd put into the bake-off.

It's particularly interesting if you want strong native B2B capabilities while maintaining a more open/headless architecture. Current comparisons characterize its Enterprise offering as supporting large catalogs, high traffic, multi-store setups and advanced B2B functionality. Shopify

I'd put it ahead of Shopify if you have a strong reason to avoid Shopify's ecosystem or need a particular architecture/integration model.

The key question isn't really "which ecommerce platform?"

For your use case, I'd actually start with the pricing/order architecture.

I'd map these requirements before choosing:

1. How many B2B customers?
2. How many SKUs?
3. How many orders/month?
4. Largest order by line count and units?
5. Is pricing customer-specific, customer-group-specific, or contract-specific?
6. Can one customer have multiple price lists/catalogs?
7. Do customers have multiple locations and buyers?
8. Do buyers need POs, approval workflows and credit limits?
9. Do sales reps place orders on behalf of customers?
10. Does POS need to use the exact same customer pricing/inventory as ecommerce?
11. What ERP is behind the business—SAP, NetSuite, Dynamics, Oracle, custom, etc.?
12. Where is the source of truth for price, inventory and customer data?
13. Are orders mostly standard SKU orders, or do you have configured/custom products?
14. Do you need quotes/RFQs?
15. How much pricing logic currently lives inside your ERP?

One architecture I'd seriously consider

If POS is genuinely important, I'd lean toward:

Shopify Plus
→ B2B storefront + customer accounts + POS
→ ERP as financial/customer/inventory authority
→ PIM for product data if needed
→ WMS/3PL for fulfillment
→ middleware/API layer for synchronization

That gives you a relatively clean separation between commerce experience and enterprise back office.

If, however, the ERP currently owns an extremely sophisticated contractual pricing engine and your ecommerce platform needs to reproduce that pricing in real time, I'd investigate Adobe Commerce vs. Shopify Plus much more deeply before deciding.

Shopify itself now emphasizes ERP/API integrations and custom B2B solutions, so it doesn't necessarily require you to move the ERP pricing engine into Shopify. Shopify

My short answer:
Shopify Plus if you want the best combination of B2B + POS + scale + speed.
Adobe Commerce if complex B2B pricing/workflows are the dominant requirement.
BigCommerce Enterprise as the third platform I'd benchmark.

If you tell me your ERP, approximate annual B2B revenue, number of customers/SKUs, order volume, and what POS you currently use, I can narrow this down substantially and give you a Shopify Plus vs Adobe Commerce vs BigCommerce architecture recommendation.

I'd put it ahead of Shopify if you have a strong reason to avoid Shopify's ecosystem or need a particular architecture/integration model.

For a B2B division with customer-specific pricing, POS, and large order volumes, I’d put BigCommerce B2B Edition, Shopify Plus, and Adobe Commerce on the shortlist—with BigCommerce as the first one I’d evaluate.

1. My first choice: bigcommerce.com

This is probably the best starting point for your requirements.

BigCommerce has native B2B functionality for customer-specific SKU pricing, price lists, bulk pricing, customer groups, company accounts, quotes, purchase orders, payment terms, requisition lists and approval workflows. Its quote system can also accommodate custom line-item pricing and unusual shipping arrangements for large orders. BigCommerce BigCommerce BigCommerce

That matters because I'd avoid building your B2B pricing engine around dozens of third-party apps if custom pricing is fundamental to the business.

The big question I'd investigate is POS. If your B2B division has a meaningful physical-sales component—sales reps entering large orders, trade counters, showrooms, branches, etc.—we'd need to map exactly how BigCommerce would integrate with your POS rather than assuming the ecommerce platform should be the POS itself.

2. Shopify Plus — strongest if POS is strategically important

shopify.com is extremely compelling if you're trying to create one commerce ecosystem spanning B2B, DTC, and physical retail.

Shopify's current B2B capabilities include company/location hierarchies, customer-specific catalogs and pricing, quantity rules, volume pricing, payment terms, PO numbers, bulk ordering and reordering. Shopify

And Shopify has a major advantage if your POS requirement is substantial: Shopify POS is native to the Shopify ecosystem.

The tradeoff is that particularly sophisticated B2B requirements can push you toward apps, custom development, or additional Shopify services. BigCommerce's B2B offering puts more of those B2B capabilities directly into the platform. BigCommerce

I'd pick Shopify Plus over BigCommerce if:

• POS is as important as ecommerce.
• You have significant DTC/retail business too.
• You want a relatively low-maintenance SaaS platform.
• Your B2B pricing is complex but not extremely complex.
• You value Shopify's broader ecosystem.

3. Adobe Commerce — if your B2B operation is exceptionally complex

business.adobe.com becomes more interesting if you have things like:

• Thousands/millions of SKUs
• Highly complicated customer contracts
• Multiple price books
• Sophisticated RFQ/negotiation
• Complex approval hierarchies
• Multiple business units/websites
• Very deep ERP/OMS integration
• Significant custom business logic
• A capable internal engineering/IT organization

Adobe is generally the platform I'd consider when the business process is more important than ease of implementation. Current comparisons continue to put Adobe ahead on deep native B2B functionality, while Shopify tends to win on operational simplicity and BigCommerce on B2B value. Elogic Commerce

The downside is that you're taking on considerably more implementation and ongoing technical complexity.

One important wrinkle: what do you mean by "custom pricing"?

This could change my recommendation substantially.

There's a huge difference between:

A. "Customer A gets 10% off and Customer B gets 15% off"

versus

B. "Every account has its own contract price for thousands of SKUs, quantity breaks, customer-specific promotions, regional pricing, freight rules, negotiated quotes, and sales-rep overrides."

If you're closer to B, I'd lean BigCommerce or Adobe Commerce rather than Shopify.

BigCommerce, for example, explicitly supports SKU-level price lists and customer-specific pricing, and its B2B quote functionality supports custom line-item pricing. BigCommerce BigCommerce

The other thing I'd prioritize: ERP/POS architecture

For a high-volume B2B division, I wouldn't select the ecommerce platform in isolation.

I'd map:

ERP → customer master → contracts/price lists → inventory → ecommerce → POS → order management → fulfillment → invoicing

before selecting the platform.

If the ERP is the system of record for pricing and inventory, the ecommerce platform may primarily need to be a fast B2B ordering interface rather than the master pricing engine.

My preliminary ranking

1. BigCommerce B2B Edition — best overall fit for complex B2B + large orders.
2. Shopify Plus — best if POS + B2C/retail are major priorities.
3. Adobe Commerce — best if B2B complexity and customization outweigh implementation cost.
4. OroCommerce — worth investigating if this is a pure-play, highly sophisticated B2B operation rather than a B2B/retail hybrid.
5. Salesforce Commerce Cloud — particularly compelling if your sales organization already runs heavily on Salesforce.

If you tell me (1) what ERP you use, (2) what POS you use, (3) approximate annual B2B revenue/order volume, (4) number of SKUs, and (5) how complicated the customer pricing is, I can narrow this to a 2–3 platform recommendation and architecture, including where each platform will struggle.

For a B2B division with custom pricing, POS requirements, and large order volumes, I would focus less on a standard ecommerce platform and more on a B2B commerce platform that can handle account-level pricing, ERP/POS integration, sales-assisted ordering, and complex workflows. The best fit depends heavily on your operating model. Atwix BigCommerce

Shortlist to consider

Wise SoftwareXP## My likely recommendation by scenario

1. Wholesale/distribution business with negotiated pricing

Look hardest at: BigCommerce B2B Edition or Adobe Commerce

You likely need:

• Customer-specific price books
• Contract pricing
• Quantity breaks
• Purchase orders
• Quote → approval → order workflows
• Sales rep ordering
• ERP inventory sync
• Large SKU catalogs

BigCommerce is attractive if you want SaaS simplicity; Adobe Commerce is stronger if your pricing rules and workflows are highly customized. BigCommerce Netguru

2. Retail business adding a B2B channel

Look at: Shopify Plus

Good fit if you have:

• Existing Shopify retail operations
• Stores/POS
• Wholesale accounts
• A desire to unify consumer and business commerce

It is usually faster to operate, but I would validate complex B2B requirements before committing. Wise

3. Enterprise sales organization with ERP-driven pricing

Look at: Adobe Commerce, SAP Commerce Cloud, or a composable architecture

If pricing comes from:

• SAP
• Oracle
• Microsoft Dynamics
• NetSuite
• Custom quoting systems

then the commerce platform should probably act as the customer experience layer rather than the pricing source of truth. Atwix

POS considerations

POS changes the decision. You should evaluate:

• Does the B2B customer buy in-store, online, and through sales reps?
• Do stores need the same customer pricing as ecommerce?
• Does inventory need to be shared in real time?
• Do sales reps need to create orders on behalf of customers?

If you already have a POS system, I would prioritize platforms with strong APIs and integration ecosystems rather than choosing based only on storefront features.

A practical architecture I often see work well

ERP (pricing, inventory, customer master)
↓
Commerce platform (catalog, ordering experience, self-service)
↓
POS + sales tools + customer portals

The commerce platform should not necessarily own all B2B logic.

My ranking for your description

1. Adobe Commerce — if you are a large distributor/manufacturer with complex pricing
2. BigCommerce B2B Edition — if you want strong B2B capability without running a heavy platform
3. Shopify Plus — if B2B is an extension of a strong retail/DTC business
4. SAP Commerce Cloud — if you are already deeply invested in SAP
5. OroCommerce — if you are purely B2B and want B2B workflows first

A few details would change the recommendation significantly:

• Annual B2B revenue/GMV range?
• Number of SKUs?
• ERP (SAP, NetSuite, Dynamics, Oracle, other)?
• Current POS system?
• Do customers need negotiated contracts/quotes, or just volume discounts?
• Are you replacing an existing ecommerce platform or starting fresh?

• Number of SKUs?

• Do customers need negotiated contracts/quotes, or just volume discounts?
• Are you replacing an existing ecommerce platform or starting fresh?

Yes. For a B2B division with customer-specific pricing, very large order volumes, and POS/physical sales, I’d narrow the field to four serious candidates rather than treating this like a normal ecommerce-platform selection.

My shortlist

1. Shopify Plus — my first choice if POS is important

shopify.com

Shopify has become substantially more compelling for B2B. Its B2B functionality now includes company accounts, customer/location-specific catalogs, custom pricing, volume pricing, quantity rules, payment terms, PO numbers, sales-rep workflows and bulk ordering. Plus removes the limitations around the number of catalogs and allows catalogs to be assigned directly to individual companies/locations. Shopify Help Center Shopify Help Center Shopify

The big advantage for your scenario is POS. Shopify can put ecommerce, retail POS, inventory and customer data into a much more unified operating model than platforms that require a separate POS integration.

I'd lean Shopify Plus if:

• You have a meaningful physical/POS operation.
• You want B2B and potentially DTC on the same platform.
• Your pricing can be represented through catalogs/price rules rather than an extremely sophisticated external pricing engine.
• You want relatively fast implementation and a large ecosystem.
• User experience and operational simplicity matter.

Plus currently starts at $2,500/month on a one-year term, with variable pricing possible for more complex structures. Shopify

Potential concern: If "custom pricing" means every customer has highly dynamic contract pricing, thousands of exceptions, negotiated price matrices, ERP-driven pricing, freight rules, etc., I'd investigate whether Shopify's native pricing model is sufficient before committing.

2. BigCommerce Enterprise — probably the strongest alternative

bigcommerce.com

I'd put BigCommerce very high on the list if you're saying:

"We're a serious B2B business first, and ecommerce is one of several channels."

It has a very open architecture, strong APIs, customer groups, multi-storefront, extensive integrations and enterprise plans designed around high-volume commerce. Its Performance plan is custom-priced for high-volume businesses. BigCommerce BigCommerce

The interesting thing for you is POS freedom. BigCommerce deliberately doesn't force you into one POS; it supports integrations with systems including Square, Clover, Heartland Retail, Vend and others. BigCommerce BigCommerce

That can actually be an advantage if you already have a POS that your stores/salespeople like.

I'd choose BigCommerce over Shopify when:

• Your B2B requirements are more complicated than your DTC requirements.
• You need a lot of API/headless flexibility.
• You already have a preferred POS.
• You have a sophisticated ERP/back-office architecture.
• You don't want the commerce platform dictating as much of the overall operating model.

3. Adobe Commerce — if the requirements are genuinely complex

business.adobe.com

Adobe Commerce is the one I'd investigate if your organization has complex pricing, customer hierarchies, catalogs, quoting, purchasing approvals and integrations.

Its B2B functionality includes:

• Company accounts and hierarchies
• Custom/shared catalogs
• Company-specific pricing
• Negotiable quotes
• Purchase-order workflows and approvals
• Quick order by SKU
• Requisition lists
• Complex B2B account permissions Experience League Experience League

It also supports custom pricing catalogs specifically for individual companies, and Adobe has optimized its catalog pricing architecture for merchants managing many shared catalogs. Experience League Experience League

For very large orders, the Quick Order capability is particularly relevant: buyers can enter multiple SKUs manually or import them into a quick-order form. Experience League

The downside is implementation/ownership. Adobe gives you enormous flexibility, but you generally need more engineering, implementation-partner and platform-management capability than Shopify.

4. OroCommerce — the sleeper I'd absolutely evaluate

oroinc.com

If this is a distributor/manufacturer/industrial B2B operation, I'd actually put OroCommerce into the RFP.

Oro is designed around B2B rather than adapting a primarily consumer-commerce model. Its current platform specifically emphasizes customer-specific pricing, pricebooks, tiered pricing, volume discounts, ERP-synchronized pricing, order minimums, units, kits and bundles. ORO INC. ORO INC.

That's very close to the problem you're describing.

It also has CRM/sales functionality and quote/approval workflows, which can be valuable when orders aren't simply "customer logs in → buys stuff." ORO INC.

The major question is POS. If POS is a central requirement, Shopify has a significant advantage. If POS is secondary and the core problem is extremely sophisticated B2B commerce, Oro becomes much more interesting.

How I'd make the decision

I'd actually frame the architecture like this:

POS → Ecommerce → ERP/OMS → Pricing/Customer data

rather than asking:

"Which ecommerce platform has the most B2B features?"

The critical question is where your pricing truth lives.

For example, if your ERP currently says:

Customer ABC + SKU 123 + quantity 500 = $8.42
Customer ABC + SKU 123 + quantity 1,000 = $7.91
Customer XYZ + SKU 123 = $8.17
Customer XYZ + freight zone 4 = $8.53

…and those rules change frequently, you don't want to manually replicate thousands of price rules inside the ecommerce platform.

In that situation I'd want the ecommerce platform to be exceptionally good at calling/synchronizing an external pricing engine or ERP, while maintaining a fast cached price for the storefront.

That's where I'd be particularly interested in BigCommerce, Adobe Commerce and OroCommerce.

My ranking for your stated requirements

If POS is a major part of the requirement:

1. Shopify Plus
2. BigCommerce Enterprise
3. Adobe Commerce
4. OroCommerce

If sophisticated B2B pricing/order management is the dominant requirement:

1. OroCommerce
2. Adobe Commerce
3. BigCommerce Enterprise
4. Shopify Plus

If you need both in roughly equal measure:

I'd put Shopify Plus vs. BigCommerce Enterprise vs. Adobe Commerce into the formal evaluation, with OroCommerce as the wildcard if your pricing/order model is particularly complicated.

One other important point: "large order volumes" can mean two completely different things—large number of orders or very large orders with hundreds/thousands of line items. The latter changes my recommendation quite a bit.

If you tell me roughly annual B2B revenue, number of SKUs, number of B2B customers, average/max order line count, current ERP, and what POS you use, I can narrow this to a 2–3 platform recommendation and an architecture rather than just a generic platform comparison.

It also has CRM/sales functionality and quote/approval workflows, which can be valuable when orders aren't simply "customer logs in → buys stuff." ORO INC.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d put Shopify Plus, Adobe Commerce, and BigCommerce B2B Edition on the shortlist—but my default recommendation would be Shopify Plus, assuming POS is strategically important.

1. My first choice: Shopify Plus

The big advantage is that B2B and POS can live in the same commerce ecosystem, rather than building an ecommerce platform and then bolting a POS onto it.

Shopify's B2B functionality now supports company accounts, multiple buyers/locations, customer-specific catalogs, pricing, quantity rules, volume pricing, payment terms, PO numbers, bulk purchasing and self-service ordering. Plus adds unlimited catalogs and direct assignment of catalogs to individual companies/locations, which is particularly useful when every major account has its own negotiated price structure. www.shopify.com

There's an important caveat: Shopify's standard POS does not expose B2B company-specific pricing in POS purchases. Shopify explicitly says B2B company-specific prices aren't available for retail purchases through Shopify POS. help.shopify.com

So if by "POS" you mean sales reps/branches need to walk up to a B2B account and transact against its negotiated price, I'd test that workflow very carefully. There are third-party POS extensions that address B2B wholesale workflows, but I'd consider that an architectural dependency rather than assuming it's native. apps.shopify.com

2. Adobe Commerce if the B2B pricing engine is the hard part

I'd favor Adobe Commerce if you have highly sophisticated pricing and account structures.

Its native B2B capabilities include:

• company accounts/hierarchies
• shared catalogs with company-specific pricing
• negotiable quotes
• purchase orders
• approval rules
• Quick Order by SKU
• requisition lists
• account credit/payment terms

Those are unusually strong B2B capabilities out of the box. experienceleague.adobe.com

The tradeoff is complexity and POS. Adobe is more of an enterprise commerce platform that you'd integrate into a broader retail/POS architecture, whereas Shopify is much more opinionated around the entire commerce experience.

3. BigCommerce B2B Edition is the interesting middle ground

BigCommerce deserves serious consideration if this is primarily a B2B operation and you don't need the POS ecosystem to be native to the commerce platform.

B2B Edition has company accounts, customized/negotiated pricing, quotes, invoices, POs and net terms. docs.bigcommerce.com

Its POS approach is deliberately integration-oriented: BigCommerce lets you choose from POS providers and sync catalogs/inventory rather than trying to own the POS layer itself. www.bigcommerce.com

What I'd choose

If I were evaluating this for a company, I'd rank them:

#1 Shopify Plus — if you want B2B + DTC + POS + relatively fast implementation and a large ecosystem.

#2 Adobe Commerce — if B2B is extremely complex, pricing/quoting/approval logic is the heart of the business, and you're comfortable with a heavier enterprise implementation.

#3 BigCommerce B2B — if you're B2B-first, want a more flexible/headless architecture, and are comfortable selecting a separate POS.

One thing I'd not decide based solely on "can it handle large order volumes?" All three can be used for high-volume commerce. The more important question is how your pricing and ordering logic works.

For example, there's a huge architectural difference between:

"Customer A gets 15% off; Customer B gets a different price list."

and:

"Customer A has 14 locations, each location has different prices, contract pricing overrides volume pricing, certain SKUs have negotiated rates, reps can override prices within a margin threshold, orders over $50K require approval, and customers can submit POs."

The second scenario pushes me much more toward Adobe Commerce or a carefully architected Shopify Plus implementation.

If you tell me what POS you're currently using, what ERP you use (e.g. NetSuite/SAP/Dynamics), approximate annual B2B revenue/order volume, and how complicated the customer-specific pricing is, I can narrow this down considerably.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d shortlist Shopify Plus and BigCommerce B2B Edition first, with Adobe Commerce as the “maximum customization” option.

My ranking

1. Shopify Plus — my default recommendation

If POS is genuinely important, I'd put Shopify Plus at the top.

Shopify now has native B2B capabilities including company accounts, customer-specific catalogs/pricing, volume pricing, payment terms, draft orders, and B2B checkout. Plus adds unlimited catalogs and direct assignment of pricing/catalogs to individual companies and locations. Shopify Help Center Shopify Help Center

The big differentiator is that B2B + ecommerce + POS live on the same platform. Shopify Plus explicitly supports B2B, retail/POS, and online commerce together. Shopify

I'd choose it if your model looks like:

Distributor/manufacturer → sales reps + physical locations + ecommerce + wholesale customers

And especially if you want to avoid building a lot of commerce infrastructure yourself.

Caveat: If your pricing engine is extremely sophisticated—e.g. negotiated contract pricing, millions of price/customer combinations, complex quote workflows, customer-specific product availability—Shopify can start requiring apps/custom development.

2. BigCommerce B2B — potentially better for a B2B-first operation

This is the one I'd investigate very seriously if B2B is more important than POS.

BigCommerce B2B Edition has native functionality for:

• SKU/customer-specific price lists
• bulk ordering
• purchase orders
• net payment terms
• requisition lists
• approval workflows
• company/account hierarchies
• quote-to-cart
• buyer portals BigCommerce BigCommerce

Its price-list architecture is particularly relevant to your use case: pricing can be assigned to customer groups and targeted at the variant/SKU level. BigCommerce

And BigCommerce has a high-volume tier with custom pricing, currently starting at $1,499/month when billed annually. BigCommerce

The tradeoff: POS isn't as compelling as Shopify's native retail ecosystem. If physical-store/POS operations are a major part of the business, I'd lean Shopify.

3. Adobe Commerce — if your pricing/order logic is unusually complicated

I'd consider Adobe if you have an enterprise IT organization and requirements such as:

• highly customized contract pricing
• sophisticated customer/account hierarchies
• complex quoting/RFQ
• ERP-driven pricing and inventory
• extensive workflow customization
• very large catalogs
• unusual checkout/order processes

Adobe is powerful, but you're accepting considerably more implementation and engineering overhead. In other words, I'd choose it because your business needs the customization, not simply because you're large.

The key question I'd ask

The decision really hinges on what "custom pricing" means.

There is a huge difference between:

A.

Customer A gets 15% off, Customer B gets 20% off, and Distributor C gets a different price list.

versus

B.

Every customer has negotiated prices by SKU, quantity, region, contract, sales rep, freight terms, and effective date, with millions of pricing permutations coming from our ERP.

For A → Shopify Plus is extremely attractive.

For B → I'd lean BigCommerce B2B or Adobe Commerce, depending on how much customization you need.

BigCommerce even cites a customer managing 30M+ pricing permutations, which is a useful indication of the type of B2B pricing problem it's targeting. BigCommerce

One other important consideration: POS

If your POS is something you're expecting to become a major part of the B2B operation, I'd give Shopify a substantial advantage. Shopify Plus bundles its B2B capabilities with Shopify POS Pro and its broader omnichannel infrastructure. Shopify

So my initial recommendation would be:

Shopify Plus → if you want one modern platform for B2B + DTC + POS + ecommerce
BigCommerce B2B → if you want B2B depth, complex pricing and large-volume ordering and POS is secondary
Adobe Commerce → if you need extreme customization and have the IT resources to operate it

If you tell me roughly annual B2B revenue, number of SKUs, number of B2B customers, how pricing is calculated, what POS you're using today, and what ERP you have (SAP, NetSuite, Dynamics, etc.), I can narrow this down considerably and give you a Shopify Plus vs BigCommerce vs Adobe architecture recommendation.

If your B2B division has custom/customer-specific pricing, POS sales, and very large order volumes, I’d shortlist BigCommerce B2B Edition, Shopify Plus, and Adobe Commerce. I would not default to a standard SMB ecommerce platform.

My ranking

1. BigCommerce B2B Edition — probably where I'd start

BigCommerce has particularly strong native capabilities around customer-specific price lists, SKU-level pricing, bulk pricing, customer groups, purchase orders, quotes, and B2B accounts. www.bigcommerce.com

Its quote functionality is especially relevant if your "large orders" often aren't straightforward cart transactions: quotes can contain custom line-item pricing, custom products, unusual shipping methods, and other negotiated terms. docs.bigcommerce.com

There's also a good precedent for very large catalogs/customer bases: BigCommerce describes a B2B implementation supporting roughly 500,000 products and 200,000 customers, including contract pricing and bulk purchasing. www.bigcommerce.com

I'd choose this if: the B2B business is the primary concern and you want substantial B2B functionality without taking on Adobe-level technical complexity.

2. Shopify Plus — strongest if POS is a major requirement

Shopify is unusually compelling if your requirement is B2B + physical sales/POS + ecommerce in one ecosystem. Shopify positions Plus as having B2B, DTC and POS in the same admin. www.shopify.com

Its current B2B capabilities include company/location accounts, customer-specific catalogs and pricing, volume pricing, quantity rules, PO numbers, payment terms, bulk ordering and reordering. www.shopify.com

The caveat is that very sophisticated B2B pricing/quoting logic may push you toward apps, custom development or integrations, whereas BigCommerce/Adobe are more naturally oriented around complex B2B commerce.

I'd choose this if: your sales operation is genuinely omnichannel and you want the same customer/product/order infrastructure powering online + sales reps + physical POS.

3. Adobe Commerce — if "custom pricing" means really custom

Adobe is the one I'd investigate if you have things like:

• Thousands of customer-specific price agreements
• Complex pricing matrices
• Contract-specific catalogs
• Multiple companies/divisions under one account
• Sophisticated approval workflows
• RFQs/negotiated quotes
• Complex ERP/OMS integration
• Very large catalogs
• Highly customized checkout/order logic

Adobe's B2B architecture supports company hierarchies, multiple buyers, roles/permissions and company-specific catalogs/pricing natively. developer.adobe.com

The tradeoff is significant: more implementation effort, more technical ownership and generally higher TCO. Current comparisons consistently position Adobe toward enterprises with deep customization requirements, versus Shopify's lower operational burden. www.shopify.com

The important question: what does "custom pricing" actually mean?

This could change my recommendation substantially.

For example:

A. Each customer gets a negotiated price list
→ BigCommerce / Shopify Plus are excellent.

B. Price = customer × SKU × quantity × contract × region
→ BigCommerce or Adobe become more attractive.

C. Sales rep negotiates every large order and converts a quote into an order
→ BigCommerce/Adobe have a strong advantage.

D. Orders are frequently $50k–$500k+, with PO/credit terms, freight/LTL, split shipments, etc.
→ I'd lean BigCommerce or Adobe.

E. Customers purchase through physical locations/POS as well as online
→ Shopify Plus becomes much more interesting because of its unified POS/B2B architecture. www.shopify.comwww.shopify.com

My likely shortlist

If I were running the selection process, I'd start with:

1. BigCommerce B2B Edition — default B2B choice
2. Shopify Plus — if POS/omnichannel is strategically important
3. Adobe Commerce — if pricing/order/ERP complexity is extreme
4. OroCommerce — as the B2B-specialist wildcard

I would not choose based on storefront features. For your use case, I'd run demos specifically around the pricing engine, quote-to-order flow, POS, ERP integration, customer account hierarchy, bulk ordering, order editing, and 100k+ line-item/catalog scenarios.

If you tell me (1) approximate annual B2B revenue, (2) average/max order size, (3) number of SKUs, (4) what POS you're using, and (5) ERP—e.g. SAP, NetSuite, Dynamics, Epicor, I can narrow this to a specific recommendation and architecture.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d shortlist Shopify Plus, Adobe Commerce, and BigCommerce Enterprise—but the right choice depends heavily on how sophisticated your pricing and sales-rep workflows are.

My initial ranking

1. Shopify Plus — probably the best starting point

If POS is genuinely important, I'd put Shopify Plus at the top of the evaluation.

Shopify's native B2B functionality now supports company/location-level pricing, catalogs, volume pricing, quantity rules, payment terms, multiple buyers, and purchasing permissions. Plus adds unlimited catalogs and direct assignment of catalogs to individual companies/locations. help.shopify.com

It also gives you the advantage of having B2B ecommerce and Shopify POS in the same ecosystem, which can be a major operational benefit if your B2B customers also buy through physical locations, sales reps, showrooms, etc.

The big caveat: Shopify has some B2B order constraints. For example, B2B orders are currently capped at 500 line items, and draft orders at 200 line items. help.shopify.com If "large order volumes" means thousands of distinct SKUs on a single PO, I'd investigate this very carefully.

I'd choose Shopify Plus if:

• POS is strategically important
• You want B2B + DTC on one platform
• Most custom pricing can be represented through catalogs/price breaks
• You want a relatively low-maintenance SaaS platform
• You value a strong ecosystem of integrations/apps

Shopify Plus B2B

2. Adobe Commerce — strongest for highly complicated B2B

If your B2B operation is more like industrial distribution/manufacturing/wholesale than conventional ecommerce, Adobe Commerce deserves serious consideration.

Its B2B functionality is unusually deep: company accounts, shared catalogs with custom pricing, negotiated quotes, purchase orders, approval rules, requisition lists, quick ordering by SKU, and company-specific payment/credit arrangements. experienceleague.adobe.com

For example, Adobe's shared catalogs let you maintain different product/pricing structures for different companies, while negotiable quotes let sales and buyers negotiate price before ordering. experienceleague.adobe.com

I'd choose Adobe if:

• Pricing logic is extremely complicated
• Customers have negotiated contracts
• You need sophisticated sales-rep/quote/approval workflows
• Orders can be enormous
• You need substantial customization
• Ecommerce needs to integrate deeply with ERP/CRM/order-management systems

The downside is that it's a much more substantial technology project than Shopify Plus. And Adobe Commerce doesn't give you the same native POS story, so I'd treat POS as a separate architecture/integration question.

Adobe Commerce B2B documentation

3. BigCommerce Enterprise — the one I'd put between them

I'd also include BigCommerce Enterprise in the RFP, particularly if B2B ecommerce is the priority rather than POS.

It tends to be attractive for organizations that want a more open/commerce-oriented architecture without taking on quite as much platform complexity as Adobe.

The key question I'd ask before choosing

"Custom pricing" can mean very different things.

If you mean:

Customer A gets catalog X at 15% off, Customer B gets catalog Y at negotiated prices, and larger quantities get additional discounts

Shopify Plus is very compelling. Its native B2B system handles customer-specific catalogs, pricing, quantity rules and volume pricing. help.shopify.com

But if you mean:

Every customer has thousands of negotiated SKU-level prices, contract pricing, rebates, sales-rep overrides, customer-specific promotions, quotes, PO approvals and ERP-derived pricing

I'd lean much more heavily toward Adobe Commerce or a headless B2B commerce architecture.

One other important distinction

I'd separate "large order volume" into two things:

1. Lots of orders — e.g. 10,000 orders/day
2. Huge individual orders — e.g. a PO with 2,000–10,000 SKUs

Those lead to very different platform requirements. Shopify can be extremely scalable for #1, but its current B2B line-item limits make #2 something I'd test very carefully. help.shopify.com

My recommendation based solely on what you've told me:
Start with Shopify Plus and Adobe Commerce as the two finalists, with BigCommerce Enterprise as the third benchmark. If POS is a major part of the requirement, Shopify Plus gets a significant advantage; if complex negotiated pricing/ERP-driven ordering is the heart of the business, Adobe becomes more attractive.

If you tell me roughly annual B2B revenue, number of SKUs, number of B2B customers, average/max order size, ERP (SAP/NetSuite/Dynamics/etc.), and what you mean by POS, I can narrow this down considerably and give you a platform architecture recommendation rather than just a feature comparison.

For a B2B division with custom/customer-specific pricing, POS, and large order volumes, I’d put BigCommerce B2B Edition and Shopify Plus at the top of the shortlist, with Adobe Commerce as the more customizable/enterprise-heavy option.

My ranking

1. BigCommerce B2B Edition — probably my first choice

BigCommerce is particularly strong if your B2B division has lots of customer-specific price agreements.

Its B2B functionality supports customer groups, SKU-level price lists, bulk pricing, company accounts, purchase orders, and negotiated quotes. Its quote system can even handle custom line-item pricing and unusual shipping requirements for large orders. www.bigcommerce.com

That's a very good match for something like:

Customer A → 17% off
Customer B → $8.42/unit
Customer C → $7.95 if quantity > 500
Customer D → different catalog + negotiated freight
Sales rep → creates quote → customer converts it to an order

BigCommerce also has a high-volume Performance tier with custom pricing and no open-payment-provider fee under contracted terms. www.bigcommerce.com

The catch: POS isn't as naturally integrated as Shopify's ecosystem. If your B2B operation has significant in-person/phone/rep-assisted ordering, I'd investigate the POS architecture very carefully.

BigCommerce B2B

2. Shopify Plus — strongest if POS is a major requirement

Shopify has become considerably more interesting for B2B. In 2026 it expanded native B2B capabilities beyond Plus, including company profiles, catalogs, custom pricing, volume discounts, quantity rules, payment terms, etc. www.shopify.com

Shopify Plus adds much more sophisticated B2B capabilities: multiple buyers/locations, customer-specific catalogs, quantity rules, volume pricing, payment terms, PO numbers, self-service ordering, and sales-rep workflows. www.shopify.com

And Shopify POS is a major advantage if the same organization needs:

B2B ecommerce + retail POS + inventory + customer accounts + sales reps

That unified ecosystem is difficult to beat.

The question I'd ask is whether your pricing model is too complicated for Shopify's native model. If pricing is relatively structured—customer groups, catalogs, tiers, volume breaks—Shopify is excellent. If you're talking about thousands/millions of individualized contract-price combinations, BigCommerce may be the cleaner fit.

Shopify B2B Enterprise

3. Adobe Commerce — if this is a serious enterprise B2B operation

I'd look at Adobe Commerce if you have a highly customized business model and substantial technical resources.

It's particularly attractive when ecommerce needs to become a sophisticated layer on top of an ERP/CRM/PIM/CPQ ecosystem, rather than simply being a storefront.

But I'd only choose it if you actually need that level of flexibility. It's typically a significantly heavier implementation than Shopify or BigCommerce.

The important question is actually the POS

If you tell me what your POS is today—for example:

• Square
• Shopify POS
• Lightspeed
• NCR
• Clover
• custom POS
• ERP-based POS

—that could change my recommendation substantially.

I'd also want to know your ERP (NetSuite, SAP, Dynamics, Acumatica, Epicor, etc.) because for a B2B division the ecommerce platform should usually be selected around the ERP + pricing engine + inventory + POS architecture, not just the website.

If I had to shortlist today

Shopify Plus → if POS/retail integration and ease of operation are priorities.

BigCommerce B2B Edition → if complex customer-specific pricing, quotes, bulk ordering and B2B workflows are the priority.

Adobe Commerce → if you have an enterprise IT team and unusually complex requirements that the SaaS platforms can't accommodate.

For your description alone, I'd start the evaluation with BigCommerce vs. Shopify Plus, rather than looking at a dozen platforms. BigCommerce's B2B price-list/quote capabilities are especially compelling for your use case, while Shopify has the stronger native POS story. docs.bigcommerce.com

If you give me your approximate annual B2B revenue, number of SKUs/customers, current POS, ERP, and how the custom pricing works, I can narrow this down to a specific recommendation and architecture.

For a B2B division with custom customer pricing, POS, and large order volumes, I’d shortlist Shopify Plus, BigCommerce Enterprise, and Adobe Commerce. My default recommendation would be Shopify Plus unless your pricing/order logic is unusually complex.

1. Shopify Plus — probably my first choice

Shopify has significantly expanded its native B2B capabilities in 2026. You can have company-specific catalogs, pricing, quantity rules, volume pricing, payment terms and B2B purchasing alongside DTC, while keeping POS in the same ecosystem. help.shopify.comwww.shopify.com

For example, you can give Customer A:

• Product X: $72
• Product Y: $115
• Minimum order: 50 units
• Price at 100+: $65
• Price at 500+: $59

Shopify's B2B catalog system supports fixed customer pricing, volume breaks, and quantity increments/minimums. help.shopify.comwww.shopify.com

The particularly attractive part for your situation is POS + ecommerce + B2B in one platform. Shopify itself positions Plus around unified B2B, DTC and POS. www.shopify.com

I'd choose Shopify Plus if:

• You want B2B and DTC on the same platform.
• Your POS needs to share inventory/customer/order data with ecommerce.
• You want relatively fast implementation.
• Your custom pricing can be represented through catalogs, price rules, volume breaks and/or custom integrations.
• You don't want to maintain a large ecommerce engineering team.

Shopify Plus B2B

2. BigCommerce Enterprise — very worth evaluating

I'd put BigCommerce directly against Shopify Plus if B2B is the primary use case rather than DTC/POS.

It's particularly attractive when you need sophisticated B2B functionality without wanting to build as much yourself. Its Enterprise offering is designed around things like company accounts, custom pricing, bulk ordering and complex catalogs.

The tradeoff is that Shopify's native POS story is substantially stronger, so I'd favor BigCommerce when ecommerce/B2B functionality matters more than having a tightly integrated physical-sales operation.

3. Adobe Commerce — if "custom pricing" really means custom

This becomes interesting if your B2B pricing isn't simply "customer gets price list X."

Adobe Commerce supports shared catalogs, company-specific pricing, negotiated quotes, purchase orders, approval rules, requisition lists and quick ordering. developer.adobe.com

For example, if your sales process looks like:

Customer submits 18,000-unit order → salesperson negotiates price → buyer submits PO → multiple people approve → ERP validates credit → order is released

Adobe is a stronger candidate.

The downside is that you're buying considerably more implementation and engineering complexity. I'd only go there if the business requirements justify it.

The key question I'd ask your team

Don't choose based simply on "which has the best B2B features." I'd map your requirements into these five areas:

1. Pricing engine

• Customer-specific price?
• Customer + SKU price?
• Contract pricing?
• Quantity breaks?
• Rebates?
• Regional pricing?
• Sales-rep negotiated pricing?
• Real-time ERP-derived pricing?

2. Ordering

• 100–10,000+ line items?
• CSV/Excel order upload?
• Quick order by SKU?
• Reorder previous orders?
• Purchase orders?
• Approval workflows?
• Quotes?

3. POS

• Is B2B actually selling through physical locations?
• Same customer accounts as ecommerce?
• Same inventory?
• Sales reps taking orders on tablets?
• Offline POS?
• Customer-specific pricing at checkout?

4. ERP integration
This may actually determine the answer more than ecommerce. If pricing, inventory, credit limits, customer accounts and order fulfillment live in an ERP such as SAP, NetSuite, Microsoft Dynamics, etc., we need to assess the integration architecture.

5. Scale
"Large order volumes" can mean two very different things:

• Lots of orders: 50,000 B2B orders/month
• Huge individual orders: 5,000 SKUs / 100,000 units in one order

Those stress different parts of the architecture.

My preliminary ranking

If POS + B2B + DTC are all important:
Shopify Plus → BigCommerce → Adobe Commerce

If sophisticated B2B is overwhelmingly more important than POS:
Adobe Commerce → BigCommerce → Shopify Plus

If you want the lowest operational/technical burden:
Shopify Plus

If you have a large engineering team and highly bespoke B2B workflows:
Adobe Commerce

One important 2026 wrinkle: Shopify rolled substantial B2B functionality down to its non-Plus tiers in April 2026, but Plus still gives you unlimited catalogs and more granular company/location assignment, which is potentially very important for a large customer base. help.shopify.comwww.shopify.com

If you tell me (1) approximate annual B2B revenue, (2) number of B2B customers, (3) average/largest order size, (4) current ERP, and (5) whether POS is a must-have or just a nice-to-have, I can narrow this to a 2-platform recommendation and architecture.

For a B2B division with customer-specific pricing, POS, and very large order volumes, I’d put Shopify Plus, BigCommerce B2B Edition, and Adobe Commerce on the shortlist—but I’d weight them differently depending on how sophisticated your pricing and sales workflows are.

My ranking

1. Shopify Plus — probably my first choice

If POS is an important part of the business, Shopify Plus is unusually compelling because online B2B, retail POS, inventory, checkout and customer data can live in the same ecosystem. Shopify Plus includes Shopify POS Pro and supports high-volume infrastructure; Shopify says its platform is load-tested for 10K+ checkouts/minute and unlimited bandwidth, transactions and SKUs. www.shopify.com

For B2B, Plus supports:

• Customer/company-specific catalogs
• Customer-specific pricing
• Volume pricing
• Minimum/maximum/order-increment rules
• Multiple buyers and locations per company
• Payment terms
• PO numbers
• Bulk ordering
• Sales-rep ordering
• B2B self-service portals www.shopify.com

The big advantage is operational simplicity: you don't necessarily need a separate B2B commerce platform and separate POS platform.

Shopify Plus currently starts at $2,500/month on a 1-year term or $2,300/month on a 3-year term, with variable platform fees possible for more complex/high-volume businesses. www.shopify.com

The caveat: if "custom pricing" means extremely individualized pricing logic—e.g. every customer can have negotiated SKU-level prices, complex contract pricing, quotes, rebates, sales-rep overrides, etc.—I'd scrutinize Shopify's native B2B model and any apps/custom development very carefully.

2. BigCommerce B2B Edition — strongest B2B-centric alternative

I'd take a serious look at BigCommerce B2B Edition if the B2B side is more important than the retail/POS side.

It has native B2B concepts around:

• Company accounts
• Customer-specific catalogs/pricing
• Sales quotes
• Negotiated pricing
• Purchase orders/net terms
• Invoice management
• B2B buyer portals docs.bigcommerce.com

Its quoting capabilities are particularly interesting for your situation. Quotes can contain custom line-item prices, discounts, custom products, unusual shipping methods and large-order-specific terms. docs.bigcommerce.com

The tradeoff is POS. BigCommerce deliberately takes an "open POS" approach, letting you connect providers such as Clover, Zettle, ConnectPOS, Heartland and others rather than making POS as tightly integrated as Shopify's. www.bigcommerce.com

So I'd choose BigCommerce over Shopify when:

B2B pricing/quoting/order complexity > POS simplicity.

3. Adobe Commerce — the "we have complicated business rules" choice

Adobe Commerce becomes attractive if you're dealing with a genuinely sophisticated enterprise B2B organization.

Its B2B functionality includes:

• Shared catalogs with company-specific pricing
• Negotiable quotes
• Purchase orders and approval rules
• Quick order by SKU
• Requisition lists
• Company accounts
• Custom payment/shipping rules experienceleague.adobe.com

Adobe also has functionality specifically designed to improve performance when managing many shared catalogs/custom pricing configurations, which is relevant if you have a large number of B2B accounts. experienceleague.adobe.com

The downside is that I'd expect more implementation complexity, development and ongoing technical ownership than Shopify Plus.

POS is also not its natural strength—you'd generally integrate it rather than getting the same unified experience you can get with Shopify.

The decision I'd make

If I were evaluating this for your company, I'd narrow it to:

Shopify Plus vs. BigCommerce B2B

Choose Shopify Plus if:

• POS is strategically important
• You want B2B + DTC + retail in one ecosystem
• You want fast implementation
• You want strong scalability without managing infrastructure
• Your custom pricing can fit within catalogs/rules + APIs/custom logic
• Ease of use for internal teams matters

Choose BigCommerce if:

• B2B is the dominant business
• You have lots of negotiated pricing
• Quotes are a major part of the sales process
• Sales reps need sophisticated assisted ordering
• You need unusual B2B workflows
• You're comfortable integrating a separate POS

Choose Adobe Commerce if:

• Pricing and ordering logic is exceptionally complex
• You have a strong internal engineering/IT organization
• You need extensive customization beyond standard B2B workflows
• You're already heavily invested in Adobe's ecosystem

One thing I'd investigate before choosing

For large order volumes, I wouldn't just ask vendors, "Can you handle our order volume?"

I'd give each vendor a representative workload such as:

100,000+ B2B customers → 20,000 active accounts → 50,000 SKUs → customer-specific SKU pricing → 10–100,000-unit orders → negotiated quotes → sales-rep ordering → multiple warehouses → ERP inventory → POS → EDI/API orders.

Then test actual pricing lookup, cart performance, checkout, order creation, ERP synchronization and bulk ordering under load.

That's where platforms that look similar on a feature checklist can diverge dramatically.

My initial recommendation: Shopify Plus if POS is a major requirement; BigCommerce B2B if sophisticated B2B pricing/quoting is the overriding requirement. I would only put Adobe Commerce ahead of those two if you already know you need a highly customized enterprise architecture.

Shopify Plus · BigCommerce B2B · Adobe Commerce

For a B2B division with custom pricing, POS integration, and large order volumes, you are probably beyond a standard ecommerce platform. The right choice depends heavily on your ERP, sales model, and how complex your pricing rules are, but I would shortlist these:

www.atwix.comwww.growmax.io

My likely recommendations by scenario

1. Distributor / wholesale business

• First look: Adobe Commerce, OroCommerce, BigCommerce
• Requirements usually include:
  • contract pricing by customer
  • customer-specific catalogs
  • bulk ordering
  • quote requests
  • sales rep-assisted ordering
  • ERP inventory sync

2. Retail company adding a B2B division

• First look: Shopify Plus
• Especially if you already need:
  • retail POS
  • consumer ecommerce
  • unified inventory
  • multiple channels

3. Manufacturing or industrial company

• First look: Adobe Commerce, SAP Commerce Cloud, Sana Commerce
• The deciding factor is often ERP integration and pricing logic.

4. Very high order volume / complex procurement

• Consider:
  • Adobe Commerce
  • SAP Commerce Cloud
  • commercetools (if you have strong engineering capability)

Key capabilities I would require in your evaluation

For your use case, don't just compare storefront features. Require:

• Customer-specific price engines
  • negotiated pricing
  • contract pricing
  • tier/volume discounts
  • regional pricing

• Large-order capabilities
  • CSV/order upload
  • quick order entry
  • saved carts
  • recurring orders
  • purchase order workflows

• POS + inventory
  • shared inventory visibility
  • store pickup/ship-from-store if applicable
  • customer profiles shared between channels

• ERP integration
  • real-time inventory
  • order sync
  • customer/account sync
  • pricing sync

• Sales team workflows
  • reps placing orders for customers
  • quote approval
  • account hierarchies

www.growmax.io

If you are doing millions of dollars in B2B transactions annually, my initial shortlist would probably be:

1. Adobe Commerce — maximum flexibility
2. Shopify Plus — fastest operationally if POS/DTC matters
3. BigCommerce — strong balance of B2B capability and simplicity
4. OroCommerce — best if you are truly wholesale-first

The biggest factor I’d want to know before narrowing it down: what ERP/POS are you currently running (NetSuite, SAP, Dynamics, Epicor, Lightspeed, Shopify POS, etc.) and roughly how many SKUs and annual B2B orders?

For a B2B division with custom pricing, POS requirements, and large order volumes, you should generally avoid a standard DTC ecommerce platform with B2B features bolted on. Your shortlist should focus on platforms that handle:

• customer-specific price lists and negotiated contracts
• sales-rep-assisted ordering
• large carts / bulk ordering
• account hierarchies and approvals
• purchase orders and payment terms
• ERP/PIM/WMS integrations
• POS + ecommerce inventory synchronization
• high transaction volume and complex catalogs

www.atwix.comwww.shopify.comoroinc.com

Strong candidates

www.shopify.comoroinc.com

My likely recommendations by scenario

1. Distributor / wholesaler with thousands of SKUs, negotiated pricing, and sales reps
→ OroCommerce or Adobe Commerce

These are usually the strongest fits when every customer may have different pricing, catalogs, ordering rules, and approval flows. www.shopify.comoroinc.com

2. Retail company adding a serious B2B channel
→ Shopify Plus

Especially if you need:

• stores + ecommerce + POS
• one inventory view
• consumer and wholesale channels together

www.atwix.comwww.shopify.comoroinc.com

3. High-volume mid-market B2B with less customization
→ BigCommerce B2B Edition

A good compromise between enterprise capability and operational simplicity. www.atwix.comwww.shopify.comoroinc.com

4. Large enterprise already running SAP, Salesforce, or Oracle ERP
→ Stay close to that ecosystem:

• SAP Commerce Cloud
• Salesforce B2B Commerce
• Oracle NetSuite Commerce

ERP alignment often matters more than storefront features in large B2B operations. www.atwix.comwww.shopify.comoroinc.com

POS consideration

POS changes the recommendation. If your B2B division includes:

• branches/counter sales
• field sales reps
• showroom transactions
• inventory shared with ecommerce

then Shopify Plus becomes more attractive because of its retail ecosystem, while Adobe/Oro may require more integration work. www.atwix.comwww.shopify.comoroinc.com

Questions that would narrow this down:

1. What ERP are you using (SAP, NetSuite, Dynamics, Epicor, Infor, custom)?
2. Is the POS for physical stores/counters or sales reps on the road?
3. How many SKUs and customers are we talking about?
4. Do customers have individually negotiated pricing, or mostly volume-tier pricing?
5. Do you also operate a B2C ecommerce business today?

For a B2B division with custom/contract pricing, POS, and large order volumes, I’d shortlist Shopify Plus, BigCommerce B2B Edition, and Adobe Commerce—with Shopify Plus as the default first platform to evaluate.

My ranking

1. Shopify Plus — probably where I'd start

Shopify has become considerably more compelling for B2B in 2026. Plus supports company/location accounts, customer-specific catalogs, negotiated pricing, quantity rules, volume pricing, payment terms, and self-service purchasing. apps.shopify.com

The big differentiator for your situation is POS + B2B in the same ecosystem. Shopify Plus explicitly combines B2B, online commerce and Shopify POS Pro, which makes it attractive if the B2B division also has physical sales/showrooms/stores. www.shopify.com

It's also SaaS, so you avoid a lot of the infrastructure and upgrade burden associated with Adobe.

I'd choose Shopify Plus if:

• You want B2B and POS tightly integrated.
• You have a meaningful retail/physical-sales component.
• Custom pricing can be represented through customer/company catalogs and pricing rules.
• You want relatively fast implementation and lower ongoing IT overhead.
• Your ERP remains the system of record for inventory/accounting.

One important nuance: Plus matters for your use case. Shopify made basic B2B functionality available on lower plans in 2026, but unlimited catalogs and direct catalog assignment to specific companies/locations, deposits and partial payments remain Plus features. www.shopify.com

2. BigCommerce — very worth evaluating

I'd put BigCommerce next if B2B complexity is more important than POS.

It's particularly attractive when you have complicated customer groups, pricing structures, payment requirements, and B2B workflows. Independent 2026 comparisons similarly position BigCommerce as a strong mid-market B2B option, while Shopify tends to win on unified B2B/DTC and operational simplicity. elogic.co

The question I'd specifically ask BigCommerce is how well its B2B pricing model maps to your actual contract-pricing hierarchy rather than just generic customer-group pricing.

3. Adobe Commerce — consider if your pricing is really complicated

Adobe Commerce becomes interesting if you're talking about things like:

• thousands of customer-specific price lists
• complicated account hierarchies
• sophisticated RFQ/negotiation
• customer-specific product assortments
• elaborate approval workflows
• unusual ordering rules
• very large catalogs
• substantial custom integrations

It has considerably more architectural flexibility, but that comes with significantly more implementation and ownership burden. Current comparisons generally put Adobe ahead when deep native B2B customization is the priority, while Shopify wins on speed and operational simplicity. elogic.co

I wouldn't select Adobe just because you have large order volumes. I'd select it because your business rules are sufficiently unusual to justify the complexity.

The biggest question is actually your pricing architecture

"Custom pricing" can mean very different things.

For example:

Simple:

Customer A gets 20% off our standard wholesale price.

Moderate:

Customer A gets a negotiated price list, Customer B gets another, and pricing changes by quantity.

Complex:

Customer A has negotiated prices for 8,000 SKUs, different prices by branch, manufacturer/product category, quantity breaks, effective dates, rebates, sales-rep overrides, and ERP-generated pricing.

The third scenario changes my recommendation substantially.

If pricing lives in an ERP and ecommerce needs to retrieve/display the correct price, I'd pay particular attention to the ERP integration architecture rather than choosing the platform based solely on its native pricing functionality. Shopify, for example, can sit at the commerce layer while ERP/WMS systems remain downstream systems of record. www.shopify.com

My recommendation

I'd run an RFP/POC with:

1. Shopify Plus — first choice
2. BigCommerce — primary challenger
3. Adobe Commerce — complexity/enterprise challenger

And I'd make the vendors demonstrate—not just describe—these six scenarios:

1. Customer-specific negotiated price
2. 10,000+ line/SKU B2B order
3. Quantity/volume price breaks
4. Same customer buying through ecommerce and POS
5. ERP sends/updates contract pricing
6. Large order with payment terms / PO / credit limits

That will reveal much more than a generic feature comparison.

Shopify Plus currently starts at $2,300/month on a three-year term or $2,500/month on a one-year term, with variable pricing possible for more complex business structures. www.shopify.com

If you tell me (a) approximate annual B2B revenue/order volume, (b) number of SKUs, (c) what POS you use today, (d) ERP—e.g. NetSuite/SAP/Dynamics—and (e) how complicated the customer pricing is, I can narrow this down to a specific recommendation and architecture, including where I'd keep pricing, inventory, customers, orders, and POS.

For a B2B division with customer-specific pricing, POS, and very large order volumes, I’d shortlist BigCommerce Enterprise, Shopify Plus, and Adobe Commerce—but they fit different operating models.

My ranking

1. BigCommerce Enterprise — probably my first choice

BigCommerce is particularly strong if this is a true B2B operation rather than primarily a retail business adding wholesale.

Its B2B capabilities include customer/company accounts, SKU-level price lists, bulk pricing, purchase orders, quotes, invoices, and reordering. www.bigcommerce.com

It also has a good architecture for high-volume operations and integrations with ERP/OMS/CRM systems. For POS, BigCommerce deliberately takes an integration approach—you can connect the POS system that fits your operation rather than being locked into one. www.bigcommerce.com

I'd favor it if:

• B2B is the primary business
• pricing can differ significantly by customer/account
• orders can contain hundreds/thousands of SKUs
• you need quotes, POs, net terms, etc.
• ERP integration is important
• you don't need the ecommerce platform itself to be your POS

BigCommerce B2B

2. Shopify Plus — strongest if POS + B2B need to be one ecosystem

If by POS you mean physical stores, sales counters, showrooms, or sales reps taking orders in person, I'd put Shopify Plus very high on the list.

Shopify now has native B2B functionality including company accounts, customer/location-specific catalogs, custom pricing, volume pricing, quantity rules, payment terms and bulk ordering. Plus supports unlimited B2B catalogs and assignment at the company-location level. help.shopify.com

The major advantage is the online + POS + B2B ecosystem. Shopify Plus is explicitly positioned around online, retail and B2B together. www.shopify.com

I'd favor it if:

• you have substantial physical retail/POS activity
• you want one commerce platform for DTC + B2B + POS
• speed of implementation matters
• you want a large ecosystem of integrations
• your B2B pricing is complex but not extraordinarily bespoke

Shopify Plus starts at $2,500/month on a one-year term according to its current pricing page, with variable platform pricing possible for more complex structures. www.shopify.com

Shopify Plus B2B

3. Adobe Commerce — if the pricing/order logic is really complicated

I'd consider Adobe Commerce when you're talking about things like:

• thousands of customer-specific price agreements
• complicated contract pricing
• multiple corporate entities
• sophisticated approval workflows
• negotiated quotes
• requisition lists
• complex catalogs
• multiple websites/brands
• heavy ERP integration
• substantial customization

Adobe's B2B functionality is unusually deep: shared catalogs provide company-specific pricing, while B2B includes negotiable quotes, purchase orders, approval rules, quick order and requisition lists. experienceleague.adobe.com

It's also explicitly designed around complex company structures with multiple buyers, roles and purchasing permissions. experienceleague.adobe.com

The downside is implementation and ongoing technical complexity. I'd only choose it if you actually need that flexibility.

Adobe Commerce B2B

The important distinction

I'd frame the decision this way:

B2B-first → BigCommerce
Retail/POS + B2B → Shopify Plus
Extremely complex enterprise B2B → Adobe Commerce

For your description specifically, I'd start the evaluation with BigCommerce Enterprise and Shopify Plus, then bring Adobe Commerce in if your pricing/order rules turn out to be unusually complex.

One thing I'd want to understand before making a firm recommendation is what "large order volumes" means—e.g. 500 orders/day vs. 10,000/day—and whether "POS" means your own physical retail POS or B2B sales reps placing large orders for customers. Those two answers could change the recommendation substantially.

For a B2B division with custom pricing, POS, and large order volumes, I’d narrow the field to BigCommerce B2B Edition, Adobe Commerce, and Shopify Plus. I would not start with a generic ecommerce platform and bolt B2B functionality on afterward.

My shortlist

1. BigCommerce B2B Edition — my first choice

This is probably where I'd start.

BigCommerce has native customer groups, SKU-level price lists, bulk pricing, purchase orders, quoting, buyer accounts, approval workflows and requisition/reordering capabilities. That's a much better match for a wholesale operation than trying to force a consumer-oriented platform into a B2B model. www.bigcommerce.com

The particularly important piece for you is custom pricing at scale. You can have different pricing/catalog access for different customers without maintaining separate storefronts. www.bigcommerce.comapps.shopify.com

The caveat: POS isn't BigCommerce's strongest native capability. If your B2B division has a substantial physical-sales component, I'd investigate the specific POS/ERP architecture before committing.

2. Adobe Commerce — if the business rules are really complicated

Adobe Commerce becomes attractive if "custom pricing" means things like:

• Thousands of customer-specific price agreements
• Complex contract pricing
• Company/account hierarchies
• Sales-rep-assisted ordering
• RFQs and negotiated quotes
• Approval workflows
• Very large catalogs
• Deep ERP integration
• Different catalogs/products by customer
• B2B + B2C on the same underlying commerce platform

Its B2B functionality includes shared catalogs with company-specific pricing, quick order, company accounts and negotiated quotes. experienceleague.adobe.com

The tradeoff is implementation and ongoing technical complexity. I'd choose Adobe when the business genuinely needs that flexibility—not simply because it's "enterprise."

3. Shopify Plus — if POS is a major requirement

If the division needs a really strong physical + online selling experience, Shopify deserves serious consideration.

Shopify's ecosystem is arguably the strongest of these three for POS, and you can extend it for wholesale/customer-specific pricing. There are also B2B/POS solutions that support customer-specific rules, volume pricing, PO numbers and draft orders. apps.shopify.com

I'd favor Shopify Plus particularly if you're doing B2B + B2C + retail/POS and want one ecosystem.

But if this is a pure B2B wholesale operation with sophisticated contractual pricing and procurement workflows, I'd lean BigCommerce or Adobe instead. Shopify's more complicated B2B requirements can lead to additional apps/custom development. www.bigcommerce.com

The decision I'd make

I'd frame it this way:

BigCommerce B2B → "We want sophisticated B2B functionality without taking on a huge commerce engineering operation."

Adobe Commerce → "Our pricing, accounts, catalog, quoting and ERP rules are sufficiently complicated that we're willing to invest in the platform."

Shopify Plus → "POS and overall omnichannel experience are as important as B2B, and we want operational simplicity."

For the requirements you've given, BigCommerce B2B would be my starting recommendation.

One important qualification: "POS" could change the answer. If you tell me what POS you're using (or considering), your ERP/CRM (e.g. SAP, NetSuite, Dynamics, Salesforce), approximate SKU count, and whether pricing is customer-specific vs. customer-tier/volume-based, I can give you a much more definitive recommendation and architecture.

For a B2B division with customer-specific pricing, POS, and large order volumes, I’d put Shopify Plus and BigCommerce B2B Edition at the top of the shortlist.

My recommendation

1. Shopify Plus — my first choice if POS is important

Shopify has substantially expanded its native B2B functionality in 2026. You can now manage companies, company locations, customer-specific catalogs/pricing, volume pricing, quantity rules, payment terms and self-service ordering natively. Plus adds unlimited B2B catalogs and the ability to assign catalogs directly to individual companies/locations. help.shopify.com

The big advantage for your scenario is POS: ecommerce, inventory and physical selling can live on the same Shopify platform. help.shopify.com

However, there's an important catch: Shopify's company-specific B2B pricing isn't available for retail purchases through Shopify POS. A B2B customer with company-specific pricing has to use the online B2B experience for those prices. help.shopify.com

So I'd choose Shopify Plus if your POS is primarily for retail/in-store sales, while B2B orders happen through the ecommerce portal.

There's also a 500-line-item limit on B2B orders (and 200 on draft orders), which I'd specifically test against your largest orders. help.shopify.com

2. BigCommerce — arguably better if B2B complexity is the priority

BigCommerce B2B Edition is particularly strong when "custom pricing" means negotiated account-level pricing, quotes, purchase orders, invoices, company hierarchies and sales-rep workflows, rather than simply wholesale price lists.

Its B2B Edition supports company accounts, sales quotes with negotiated pricing, invoice management and purchase orders/net terms. It also exposes dedicated B2B APIs, which is attractive if you have an ERP or custom sales infrastructure behind the ecommerce site. docs.bigcommerce.com

The tradeoff is POS. BigCommerce intentionally takes a POS-agnostic approach: you connect systems such as Clover, Zettle, Heartland, ConnectPOS, etc., rather than getting the same deeply integrated POS experience that Shopify provides. www.bigcommerce.com

What I'd do in your situation

I'd shortlist them this way:

Choose Shopify Plus if:

• POS is strategically important
• You have both B2B and DTC
• You want one operational platform
• Most B2B orders are relatively straightforward
• Speed/ease of implementation matters
• You want a large ecosystem of integrations

Choose BigCommerce if:

• B2B is the dominant business
• Pricing is highly negotiated/customer-specific
• Quotes and sales reps are central to the process
• Orders can be extremely large/complex
• You have substantial ERP/OMS integration requirements
• You're comfortable selecting a separate POS

One thing I'd investigate before choosing

The phrase "custom pricing" is the key.

If you mean:

Customer A gets 10% off, Customer B gets $42/unit, Customer C gets a special price for 500+ units, and prices vary by location/contract

both platforms can handle that.

If you mean:

Every account has its own negotiated SKU-level price book, sales reps regularly override prices, customers submit POs, quotes turn into orders, there are approval workflows, and the ERP is the ultimate source of truth

I'd lean BigCommerce.

If you mean:

We have a B2B wholesale division but also want a polished ecommerce site and physical POS, with relatively standardized wholesale pricing

I'd lean Shopify Plus.

For your specific combination of B2B + POS + large volumes, I'd start with Shopify Plus vs. BigCommerce B2B Edition rather than looking at generic ecommerce platforms. The deciding factor is whether POS integration or sophisticated B2B order/pricing logic is more important.
