For a small B2B parts supplier with a handful of wholesale customers, the key question is how complex your pricing rules are. You probably don’t need an enterprise platform unless you have thousands of SKUs, complex contracts, ERP pricing, or many buyer roles.

Here’s how the main options stack up for customer-specific pricing:

BigCommerce ShopifyFor your situation, I’d usually shortlist:

1. BigCommerce B2B — likely the strongest fit

If you have customers like:

• Customer A gets 15% off bearings
• Customer B sees different prices for the same SKUs
• Some customers can buy only certain product ranges
• You want customers to log in and reorder

BigCommerce’s B2B tools are designed around that model, including customer groups and price lists that can be assigned to individual accounts or groups. BigCommerce

2. Shopify — best if simplicity matters

Shopify is attractive if you want:

• Easy product management
• A polished website
• Less technical maintenance
• A future retail/DTC channel alongside wholesale

Its B2B capabilities have improved substantially, but very granular industrial pricing models may require careful checking or integrations. Snapshot Design

3. WooCommerce — best budget/custom option

If you only have, say, 5–50 wholesale accounts and relatively simple rules:

• Customer login → see wholesale prices
• Different discount tiers
• Minimum order quantities

WooCommerce can work well, but you’ll typically rely on extensions and configuration rather than native B2B workflows.

What I’d avoid initially

I would probably not start with OroCommerce, Adobe Commerce, or other enterprise B2B suites unless you need things like:

• Multiple buyer roles per customer company
• Complex approval workflows
• ERP-driven contract pricing
• Thousands of customer-specific price lists

Those platforms are powerful but can be expensive and require more implementation effort. Alkali

A few details would change the recommendation:

1. Roughly how many SKUs do you sell?
2. How many wholesale customers need unique pricing?
3. Are prices negotiated per customer per part, or mostly discount tiers (e.g., “all wholesalers get 20% off”)?
4. What system currently holds your stock/pricing (Sage, Xero, QuickBooks, ERP, spreadsheet, etc.)?

For your setup, BigCommerce is worth a close look. Its built-in B2B price lists can set SKU-level prices for individual wholesale accounts or customer groups, which maps well to negotiated customer pricing. BigCommerce BigCommerce

Shopify also handles customer-specific catalogs/pricing, but the most granular direct company-location assignment is on Shopify Plus. Shopify Help Center Shopify Help Center

For a small parts supplier with only a few wholesale customers, I’d compare BigCommerce vs Shopify Plus primarily on pricing complexity, ERP integration, and total cost.

For a small B2B parts supplier with a few wholesale customers, the “best” platform usually comes down to how complex your customer pricing is. You probably do not need the most powerful enterprise system; you need something that handles:

• Customer-specific price lists (“Customer A pays $4.20, Customer B pays $3.90”)
• Contract pricing by SKU
• Customer groups
• Hidden wholesale catalogs
• Quick reorders
• Minimum quantities / case packs
• Purchase orders or invoice terms
• ERP/accounting integration (if applicable)

Here’s how the main options compare:

BigCommerce Shopify### My shortlist for your situation

1. BigCommerce B2B Edition — likely the strongest fit

• Handles customer-specific price lists without building everything yourself.
• Lets you assign pricing to individual accounts or groups.
• Good for parts catalogs where many SKUs have different customer prices. BigCommerce

2. Shopify Plus — best if you may sell both wholesale and direct online

• Great storefront experience.
• Strong if your wholesale customers are only part of the business.
• Less ideal if your operation is mostly industrial distribution with negotiated pricing. Shopify

3. WooCommerce + B2B plugins — best budget option

• A good choice if you have, say, 5–50 wholesale customers and modest catalog complexity.
• You can create customer groups and pricing tiers, but you’ll be managing more pieces yourself.

A practical rule of thumb

• <100 wholesale customers, <5,000 SKUs, simple negotiated pricing: WooCommerce or Shopify can work.
• Hundreds of SKUs with different prices per customer: BigCommerce is usually easier.
• Complex distributor workflows (quotes, approvals, multiple buyers per company, ERP-driven pricing): Adobe Commerce or a dedicated B2B platform.

A few details would change the recommendation:

1. Roughly how many SKUs do you sell?
2. Do customers have fixed negotiated prices or just discount tiers?
3. Are you currently using an ERP/accounting system (QuickBooks, NetSuite, SAP, etc.)?
4. Do customers need to log in and see their own pricing, or do you just need an ordering portal?

For a small B2B parts supplier with a handful of wholesale accounts, customer-specific pricing is one of the main things I’d optimize for. You probably don't need a massive enterprise platform unless your pricing rules are unusually complex.

My ranking

1. Best for sophisticated pricing: Adobe Commerce

Adobe Commerce has particularly strong native B2B functionality. Its Shared Catalogs let you create a custom catalog with custom prices and assign it to specific companies. You can also combine that with customer-group and quantity/tier pricing. Experience League Experience League

For example:

• Customer A → $82 for Part X
• Customer B → $76 for Part X
• Customer C → $69 for Part X
• All three → different quantity breaks
• Some customers → don't see certain products at all

That's very close to the way a traditional parts distributor operates.

The downside is complexity and cost. For only a few wholesale customers, Adobe Commerce may be considerably more platform than you need.

2. My likely recommendation for you: Shopify B2B

Shopify B2B has catalogs that can be assigned to individual company locations, allowing you to give different customers different pricing. It also supports quantity rules and volume pricing. Shopify Help Center Shopify Help Center

So you could structure it like:

Wholesale Customer A → Catalog A → their negotiated prices
Wholesale Customer B → Catalog B → their negotiated prices
Wholesale Customer C → Catalog C → their negotiated prices

For a small operation, I'd strongly consider this because the administrative simplicity may matter more than having the absolute most powerful pricing engine.

3. BigCommerce is worth serious consideration

BigCommerce is particularly attractive if you're primarily B2B rather than selling consumer products with a B2B side.

I'd put it roughly between Shopify and Adobe: more B2B-oriented than a typical Shopify setup, but generally less heavyweight than Adobe Commerce.

What I'd choose in your situation

If you have 5–20 wholesale customers, each with negotiated prices, I'd start by looking at:

Shopify B2B → BigCommerce B2B → Adobe Commerce

I'd choose Shopify if your pricing model is basically:

"Each customer gets their own price list, plus occasional quantity breaks."

I'd choose BigCommerce if you want the store to feel more like a traditional B2B ordering portal.

I'd choose Adobe Commerce if you're saying:

"Customer pricing varies by product, customer, quantity, catalog visibility, contract, region, and there are lots of exceptions."

Adobe's B2B system is explicitly designed around company-specific catalogs and pricing, including separate custom catalogs that are only visible to assigned companies. Experience League Experience League

One important question would change my recommendation: are your customer prices mostly a fixed price list per customer (e.g. Customer A gets 20% off everything), or do you have thousands of individually negotiated SKU prices (e.g. A gets $14.20 for SKU-123 while B gets $13.75)?

For a small B2B parts supplier with a handful of wholesale accounts and customer-specific pricing, I’d put BigCommerce B2B at the top of the list.

My ranking

1. BigCommerce B2B — best fit

• Its Price Lists let you set pricing down to the individual SKU/variant and assign those prices to customer groups or individual wholesale accounts. BigCommerce BigCommerce
• You can effectively have: - Customer A → its negotiated prices
• Customer B → a different price list
• Customer C → another price list
• Everyone else → standard pricing
• It also supports customer-specific products, reorder workflows, approval processes, and B2B buyer accounts. BigCommerce BigCommerce
• This is particularly attractive for parts distribution, where you may have hundreds/thousands of SKUs but only a few customers with negotiated price files.
• Adobe Commerce (Magento) B2B — most powerful, but probably overkill

• Adobe has an excellent B2B model based around shared catalogs, where each company can have its own product assortment and custom pricing. Experience League Experience League
• It also supports customer-group pricing and quantity/tier pricing. Experience League Experience League
• I'd choose this if your pricing logic is unusually complicated or you expect the operation to become much larger.
• The downside is substantially more implementation/maintenance complexity.
• Shopify B2B — easiest ecosystem, but less compelling for your specific use case

• Shopify B2B catalogs let you customize products and pricing for companies/company locations. Shopify Help Center
• Shopify Plus gives you unlimited catalogs and direct assignment to companies and locations; lower plans have more limited catalog assignment. Shopify Help Center
• It's a very good choice if ease of use, storefront quality, and the broader Shopify ecosystem matter more than having particularly sophisticated wholesale pricing.

What I'd choose in your situation

If you told me:

"I have 10–50 wholesale customers. Each has an agreed price on some or most of my parts. I want customers to log in and automatically see their prices."

I'd choose BigCommerce B2B.

The key distinction is that BigCommerce's price-list model maps very naturally to a parts distributor's pricing file: SKU → customer/price group → negotiated price. Its documentation explicitly supports assigning price lists to customer groups and using those assignments to personalize logged-in customer pricing. BigCommerce

I'd only move toward Adobe Commerce if you have very complex pricing/catalog rules, and I'd choose Shopify if you prioritize simplicity and the Shopify ecosystem over wholesale-specific flexibility.

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has a completely different price on each part, I can narrow this down to the best 2–3 options and explain what the setup would look like.

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize customer-specific price lists/catalogs, easy account management, and low platform overhead rather than a heavyweight enterprise B2B system.

My shortlist

1. Shopify — probably my first choice

shopify.com now has native B2B functionality. You can create catalogs with specific products and prices and assign them to wholesale customers. Basic/Grow/Advanced support up to 3 active B2B catalogs, while Shopify Plus removes that limit and allows catalogs to be assigned directly to individual companies/company locations. Shopify Help Center Shopify Help Center

For example:

• Customer A → 15% off your standard parts pricing
• Customer B → their own negotiated SKU prices
• Customer C → can buy only certain product lines
• All three → different payment terms and quantity rules

Shopify can also handle volume pricing and quantity rules natively. Shopify Help Center

The important caveat: if every one of your wholesale customers has a completely different negotiated price for hundreds/thousands of SKUs, the lower Shopify plans become restrictive because of the 3-catalog limit. Plus supports unlimited catalogs and direct customer-level assignment. Shopify Help Center

2. BigCommerce — worth a serious look for parts distribution

bigcommerce.com is particularly interesting if your pricing structure is more complicated.

BigCommerce's current platform includes Price Lists, which provide SKU-level custom pricing for customer groups; that capability is on the higher-tier plans. BigCommerce

I'd lean toward BigCommerce over Shopify if you have things like:

• Lots of SKUs
• Different price lists by customer/account
• Complex product options
• Multiple price breaks
• Wholesale customers ordering large quantities
• A need to expose more of your product catalog while controlling each customer's price

3. Adobe Commerce — powerful, but probably overkill

experienceleague.adobe.com can do extremely sophisticated B2B pricing and account structures, but for a small supplier with a few wholesale customers, I'd generally avoid it unless you have unusually complicated ERP/inventory/pricing requirements.

What I'd choose in your situation

If you have 5–20 wholesale customers, and each customer basically has a negotiated price list, I'd start with Shopify.

If you have hundreds of wholesale accounts or highly complicated SKU/customer pricing, I'd investigate BigCommerce first.

One particularly important question is how your pricing actually works. For example, there's a big difference between:

"Customer A gets 20% off everything."

and

"Customer A pays $14.72 for SKU 123, $8.31 for SKU 456, has a different price break at 25 units, and can't buy certain SKUs."

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has their own SKU-level price list, I can narrow this down to the best 2–3 options and explain what I'd use.

For a small B2B parts supplier with a handful of wholesale customers, the “best” platform depends on how complicated your pricing rules are. If you have negotiated prices by account (e.g., Customer A pays $8.50 for part X, Customer B pays $7.90), you’ll want native customer-specific pricing, not just discount codes.

Here are the strongest fits:

For your situation, I’d usually shortlist:

1. BigCommerce B2B Edition — if you have:

• 5–100 wholesale accounts
• a few hundred to tens of thousands of parts
• customers who log in, see their pricing, reorder, and pay online

It gives you customer groups and price lists without building a custom system. BigCommerce BigCommerce

2. OroCommerce — if you have:

• every customer on a different negotiated price sheet
• lots of exceptions (“this customer gets this part at this price until this date”)
• sales reps quoting frequently
• ERP-driven pricing

It is more purpose-built for distributors and manufacturers. ORO INC. ORO INC.

3. WooCommerce + B2B extensions — worth considering if you’re very small and already comfortable with WordPress, but I’d be cautious if pricing rules are central to your operation.

A few questions would narrow this down a lot:

• Roughly how many SKUs/parts do you sell (100, 5,000, 50,000+)?
• Are prices negotiated per customer, or are customers grouped into tiers (Dealer, Distributor, VIP)?
• Do you need customers to see inventory/lead times from an ERP?
• Are you replacing an existing website, or starting from scratch?

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize a platform where you can say:

“Customer A sees $42, Customer B sees $38, and everyone else sees $55.”

without building a pricing system from scratch.

My shortlist

1. Shopify B2B — probably the best fit for you

Shopify has substantially improved its native B2B functionality in 2026. You can create B2B catalogs with customer-specific prices and product availability, as well as volume pricing and quantity rules. Shopify Help Center Shopify

The important distinction is the plan:

• Basic/Grow/Advanced: up to 3 active B2B catalogs across your B2B markets.
• Shopify Plus: unlimited catalogs and, crucially, the ability to assign a catalog directly to an individual company/company location. Shopify Help Center

So if you have, say:

• Wholesale Customer A → 20% off
• Wholesale Customer B → fixed negotiated prices
• Wholesale Customer C → different prices on 50 specific parts
• Everyone else → retail price

Shopify Plus handles that natively quite nicely. Shopify Help Center

The catch is that Plus currently starts around $2,500/month on a 1-year US term, so I wouldn't recommend Plus merely because you have a few wholesale customers. Shopify Help Center

2. Adobe Commerce B2B — strongest for complicated pricing

Adobe Commerce is arguably more capable if your pricing model gets complicated. Its B2B functionality has shared catalogs with custom pricing for different companies, and buyers can be restricted to particular catalogs. It also supports B2B quotes and company-specific payment/shipping configurations. Experience League Experience League

I'd consider it if you eventually have things like:

• hundreds/thousands of customer-specific prices
• complex customer groups
• negotiated quotes
• large product catalogs
• ERP integration
• complicated permissions and purchasing workflows

For “we have 5–20 wholesale accounts and need each one to see its negotiated prices,” though, it's probably more machinery than you need.

What I'd choose for your situation

Start with Shopify B2B unless your pricing rules are unusually complicated.

And there's an important wrinkle: since Shopify rolled native B2B features down to its non-Plus plans in 2026, you may not need Plus initially. You can use up to three catalogs to represent, for example:

• Standard wholesale
• Preferred wholesale
• Distributor

Shopify Shopify Help CenterIf each of your customers has truly unique pricing, rather than belonging to a few pricing tiers, that's when I'd look much more closely at Shopify Plus vs. BigCommerce B2B vs. Adobe Commerce.

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has thousands of individually negotiated prices or just a discount/tier, I can narrow this down to the best 2–3 options for your exact setup.

For a small B2B parts supplier with a handful of wholesale customers, I’d shortlist Shopify, BigCommerce, and WooCommerce—but the best choice depends heavily on how individualized your pricing is.

My pick: Shopify if you want simplicity

Shopify has become surprisingly strong for B2B. Its native B2B functionality now includes customer/company accounts, catalogs, customer-specific pricing, volume pricing, quantity rules, payment terms, and wholesale ordering. Shopify Shopify Help Center

The important caveat: on Basic/Grow/Advanced, you can have up to 3 active B2B catalogs across your markets. Shopify Plus removes that limitation and lets you assign catalogs directly to individual companies/company locations. Shopify Help Center Shopify Help Center

So if your customers fall into, say:

• Customer Group A → 20% off
• Customer Group B → 15% off
• Customer Group C → negotiated pricing

Shopify is very attractive.

If every customer has their own negotiated price for hundreds of SKUs, Shopify Plus becomes considerably more compelling.

BigCommerce: probably the strongest pure-B2B fit

bigcommerce.com has native price lists and customer groups, allowing pricing and catalogs to vary by customer group, contract, location, or buyer tier. BigCommerce

I'd lean toward BigCommerce if your business is primarily wholesale and you expect the B2B side to become more sophisticated—multiple price lists, complex accounts, sales reps, quotes, etc.

WooCommerce: most flexible for unusual pricing

woocommerce.com can be extremely flexible because its B2B extensions can price products by role, customer, quantity, product, category, etc. Some extensions even support a special price for an individual customer. WooCommerce WooCommerce

The tradeoff is that you're assembling more of the system yourself—WordPress, WooCommerce, B2B extensions, hosting, maintenance, etc.

What I'd choose for your situation

One important detail: if by "customer-specific pricing" you mean Customer A sees $8.40 for part #123, Customer B sees $7.95, and Customer C sees $9.10, rather than simply "all wholesalers get 20% off," I'd prioritize BigCommerce or WooCommerce unless you're comfortable with Shopify Plus. Shopify's current non-Plus B2B setup is more constrained because direct company-specific catalog assignment is a Plus feature. Shopify Help Center Shopify Help Center

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has unique prices or just different discount levels, I can narrow this down to the best 1–2 options for your business.

For a small B2B parts supplier with a handful of wholesale accounts, customer-specific pricing is the feature I’d optimize around, rather than choosing a platform primarily for its general ecommerce features.

My shortlist

1. 🥇 WooCommerce — probably my pick for you

If you have, say, 10–50 wholesale customers and each may have negotiated prices, WooCommerce can be extremely flexible.

Its B2B tooling can handle pricing for an individual customer, as well as role-based pricing, fixed prices, percentage adjustments, quantity breaks, and product/category rules. WooCommerce

That means you can have:

• Customer A → $18.50 for Part #123
• Customer B → $17.25 for Part #123
• Customer C → standard wholesale price
• All other customers → don't see wholesale pricing

There are also WooCommerce extensions specifically designed around customer-specific price lists. GG Addons

The downside is that you assemble the B2B functionality yourself. You're responsible for WordPress hosting, updates, plugins, security, etc.

2. 🥈 BigCommerce — best if you're becoming more B2B-heavy

BigCommerce is particularly interesting if your customers are going to need actual company accounts, multiple buyers, price lists, quotes, and purchasing workflows.

Its B2B system allows price lists to be associated with customer groups and companies, giving companies individualized pricing. BigCommerce

I'd choose this over WooCommerce if you're expecting the business to grow from "a few wholesale customers" into a proper B2B ordering portal.

3. Shopify — easiest, but I'd look closely at the plan

Shopify's native B2B functionality has catalogs and customer/company-specific pricing, and can also handle quantity rules and volume pricing. Shopify Plus expands this considerably, including direct catalog assignment to companies and locations. Shopify Help Center

The catch is that if your requirement is "every customer has their own negotiated price for lots of individual SKUs", I'd want to map your pricing model carefully before committing to Shopify. You don't want to discover later that you're depending on a collection of apps to reproduce a proper B2B price-list system.

What I'd do in your situation

If you told me:

"We're a small parts distributor. We have 15 wholesale accounts. Each account gets negotiated pricing on some products, and customers mostly reorder the same parts."

I'd probably choose WooCommerce + a good B2B/customer-specific pricing extension.

It's inexpensive relative to an enterprise B2B platform and gives you very granular control. WooCommerce's current B2B options can explicitly prioritize an individual customer's price over role-based pricing, which is exactly the kind of hierarchy a negotiated-parts business often needs. WooCommerce

If instead you said:

"We're going to have hundreds of accounts, multiple buyers per company, sales reps, quotes, purchase orders, and sophisticated account management."

I'd lean BigCommerce B2B.

And if your priority is "I don't want to maintain a website; I just want something polished that works", I'd investigate Shopify B2B.

If you tell me roughly how many SKUs you have, how many wholesale customers, whether each customer has completely different prices or just different discount levels, and whether you need customers to log in to see their prices, I can narrow this down to a specific platform + pricing setup.

For a small B2B parts supplier with a handful of wholesale customers, the “best” ecommerce solution is usually the one that handles account-level price lists, customer groups, hidden pricing, quick reorders, and simple admin without forcing you into an enterprise implementation.

My shortlist:

BigCommerce Shopify### My likely recommendation for your situation

1. BigCommerce B2B Edition — strongest “out of the box” choice

• Create each wholesaler as an account.
• Assign a customer-specific price list.
• Give different customers different SKUs, discounts, and reorder experiences.
• Avoid stitching together lots of apps.

BigCommerce specifically supports customer groups and price lists that can be assigned to individual wholesale accounts or groups. BigCommerce

2. WooCommerce — best if you have only a few accounts and want simplicity
A common setup:

• WordPress + WooCommerce
• B2B pricing plugin
• Customer roles (Dealer A, Dealer B, Distributor, etc.)
• Each role sees its own pricing

This can be very cost-effective if your catalog is modest and you already have someone comfortable maintaining a website.

3. Shopify — best if you might add consumer sales later
If you sell parts both wholesale and retail, Shopify can be attractive because you can run both channels together. Its B2B features support company accounts, custom catalogs, pricing, and payment terms, though some advanced wholesale needs may depend on your plan or extensions. Shopify

Features I would prioritize for a parts supplier

Before choosing, make sure it handles:

• Customer-specific price lists (not just discount codes)
• SKU-level pricing overrides
• Customer login with hidden wholesale pricing
• Quick order by part number
• CSV upload/order forms
• Reorder from previous purchases
• Minimum quantities/case packs
• Net terms or purchase orders
• Integration with your inventory/accounting system

For a small supplier, I’d generally rank them:

1. BigCommerce — if wholesale is the core business
2. WooCommerce — if you have a small catalog and want low cost/flexibility
3. Shopify — if you may add direct-to-consumer sales
4. Adobe Commerce/OroCommerce — only when pricing rules become genuinely complex

A few details would change the recommendation:

• How many SKUs/part numbers do you sell?
• Do your customers each have negotiated prices, or are they in tiers (dealer/wholesale/distributor)?
• What system holds inventory today (QuickBooks, NetSuite, ERP, spreadsheets, etc.)?

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize platforms where you can say:

“Customer A sees one price for SKU 123, Customer B sees another, and everyone else sees the normal price.”

My shortlist

🥇 I'd look at BigCommerce first

bigcommerce.com

BigCommerce has native price lists that can customize prices down to the individual SKU and assign those prices either to customer groups or individual wholesale accounts. BigCommerce BigCommerce

That's particularly well suited to parts distribution because you can have something like:

• Wholesale Customer A: SKU-100 = $8.25
• Wholesale Customer B: SKU-100 = $7.80
• Wholesale Customer C: SKU-100 = $9.10
• New/guest customer: SKU-100 = $12.00
• Customer A also gets different volume breaks on selected SKUs

And you don't necessarily need a separate storefront for each customer.

Shopify Plus is also excellent—but I'd hesitate

help.shopify.com

Shopify's B2B system now supports catalogs with customer/company-specific products and pricing, including direct assignment to companies and locations on Plus. It also supports volume pricing and quantity rules. Shopify Help Center Shopify Help Center

The catch for your situation is Shopify Plus. If you're only serving a few wholesale accounts, I'd question whether paying for Plus makes sense unless you also want Shopify's broader ecosystem and excellent storefront/admin experience.

Adobe Commerce is the "serious distributor" option

experienceleague.adobe.com

Adobe Commerce has perhaps the richest native B2B pricing model here. Its Shared Catalogs allow custom catalogs and pricing for individual companies, including fixed or percentage-based SKU pricing and quantity-based tier pricing. Experience League Experience League

It also has native B2B quotes, company accounts, quick ordering, requisition lists, etc. Experience League Experience League

But for a small supplier with only a few wholesale customers, I'd generally consider it too much platform for the problem unless your parts catalog, pricing rules, ERP integration, or organizational complexity is substantial.

What I'd choose in your shoes

BigCommerce if your main requirement is:

“I need a straightforward online catalog where each wholesale customer can log in and automatically see their negotiated prices.”

It's particularly attractive if you have hundreds/thousands of parts and lots of SKU-level exceptions.

I'd choose Shopify Plus instead if you're also building a substantial DTC business and want Shopify's overall ecosystem.

I'd choose Adobe Commerce if you're closer to a traditional distributor with complex account structures, thousands of customer-specific prices, ERP integration, quotes, purchasing workflows, etc.

If you tell me roughly (1) number of SKUs, (2) number of wholesale customers, (3) whether customers have negotiated prices per SKU or just a discount %, and (4) what accounting/ERP system you use, I can narrow this down to the best 1–2 options for your particular setup.

For a small B2B parts supplier with a handful of wholesale accounts and negotiated customer-specific prices, I’d narrow it to BigCommerce, WooCommerce, and Adobe Commerce.

My ranking

What I'd choose in your situation

BigCommerce would be my first look.

The important distinction is that you don't merely want "10% off for wholesalers." You probably have something more like:

• Customer A → Part 123 = $8.40
• Customer A → Part 456 = $17.25
• Customer B → Part 123 = $7.95
• Customer C → Part 123 = $9.10
• Everybody else → standard price

BigCommerce's price-list system is designed around this kind of SKU-level pricing and can assign price lists to customer groups/accounts. BigCommerce BigCommerce

WooCommerce is arguably even more flexible if you're comfortable with WordPress. Its B2B tooling supports pricing for a specific individual customer, rather than requiring everything to be organized into customer groups. WooCommerce The tradeoff is that you'll typically be assembling the B2B functionality from extensions rather than getting as much of the architecture in the core platform.

Adobe Commerce is the heavyweight option. Its B2B shared catalogs can give each company its own catalog and custom prices, but for "we have 5–30 wholesale customers," I'd consider it considerably more platform than you need unless you're also dealing with complex purchasing workflows, quotes, company hierarchies, etc. Experience League

One thing I'd specifically look for

For a parts business, pricing isn't the only B2B feature that matters. I'd prioritize:

1. Individual customer/SKU pricing
2. Customer-specific product availability
3. Quantity breaks / case-pack pricing
4. Quick order by SKU
5. CSV import/export of price lists
6. Customer-specific payment terms
7. PO numbers
8. Reorder functionality
9. Ability to hide wholesale prices from non-approved users
10. Easy bulk updates when your cost/pricing changes

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has mostly unique prices or just 2–5 pricing tiers, I can tell you which platform I'd actually pick and what the setup would look like.

One thing I'd specifically look for

For a parts business, pricing isn't the only B2B feature that matters. I'd prioritize:

For a small B2B parts supplier selling to a handful of wholesale customers, I would prioritize platforms that handle customer-specific price lists, customer groups, hidden catalogs, quick reordering, and negotiated pricing without forcing you into an enterprise implementation. Shopify AFCommerce

My shortlist:

Alkali AFCommerce### My recommendation for your size

1. BigCommerce B2B Edition — likely the best match

• Create a customer account for each wholesaler.
• Assign each customer their own price list or discount structure.
• Let customers log in and see their negotiated pricing.
• Support bulk ordering and repeat purchases.

This maps closely to how parts distributors usually operate. AFCommerce

2. Shopify + B2B features/apps — best if you want simplicity
Choose this if you might eventually sell:

• retail/direct-to-consumer,
• marketplace orders,
• branded products,
• marketing-driven sales.

Shopify is easier to run day-to-day, but very complex contract pricing (hundreds of customer-specific rules, unusual price formulas, etc.) may need additional tooling. Kibo

3. WooCommerce — best if your pricing is unusual
Good if you need rules like:

• Customer A gets 18% off SKU family X
• Customer B gets fixed contract pricing
• Minimum quantities by customer
• Custom approval flows

The tradeoff is you become more responsible for hosting, updates, and plugin compatibility.

For a parts supplier, I would look for these specific features:

• ✅ Customer login with private pricing
• ✅ Multiple price tiers (dealer, distributor, VIP)
• ✅ SKU search by part number
• ✅ CSV bulk ordering
• ✅ Saved carts / reorder history
• ✅ Customer-specific product visibility
• ✅ Quote requests
• ✅ ERP/accounting integration (if you use one)

A couple of questions would narrow this down a lot:

1. Roughly how many SKUs/parts do you carry (100, 10,000, 100,000+)?
2. Are your wholesale customers all on fixed negotiated prices, or do you mostly use discount percentages off a list price?
3. Do you already use an ERP/accounting system (QuickBooks, NetSuite, Epicor, Sage, etc.)?

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize customer-specific SKU pricing, easy price-list management, and low administrative overhead over the broader “B2B feature checklist.”

My pick: BigCommerce

BigCommerce is probably the strongest fit for your situation.

Its price lists are particularly well suited to parts distribution: you can set different prices down to the individual SKU/variant and assign those prices to customer groups or individual wholesale accounts. BigCommerce BigCommerce

That gives you a structure like:

• Customer A: 15% off most parts, but negotiated prices on 20 SKUs
• Customer B: completely different pricing
• Customer C: same pricing as A, so both can share a price list
• Retail/public visitors: normal list price

BigCommerce's B2B company accounts also tie buyers to customer groups, which control the products and pricing they see. BigCommerce BigCommerce

Shopify is now a much closer second

Shopify changed its B2B offering substantially in 2026. Basic/Grow/Advanced now have native B2B catalogs, pricing, company accounts, payment terms, volume pricing, etc. Shopify Shopify Help Center

However, there's an important distinction for your use case:

• Basic/Grow/Advanced: up to 3 active B2B catalogs across B2B markets
• Shopify Plus: unlimited catalogs and direct assignment of catalogs to individual companies/company locations Shopify Help Center Shopify Help Center

So if you have, say, 5–20 wholesale customers and each has negotiated pricing, I'd lean BigCommerce rather than paying for Shopify Plus just to get granular customer-specific catalogs.

Quick comparison

One important question

The recommendation changes quite a bit depending on how your pricing actually works.

If you tell me something like:

“I have 12 wholesale customers. Each gets a different discount off my master price list, but about 30 parts have individually negotiated prices. They need to log in and see their prices, and I want to upload/update pricing from Excel.”

…I can narrow this down to BigCommerce vs Shopify vs WooCommerce, including what the actual setup would look like and which is likely to be cheapest/easiest for you.

For a small B2B parts supplier with a handful of wholesale customers, I’d put BigCommerce first if customer-specific pricing is the main requirement.

My ranking

1. BigCommerce — my pick

BigCommerce has native price lists that can set prices down to the individual SKU and assign those prices to specific wholesale accounts or customer groups. BigCommerce

That's particularly attractive for your situation. For example:

• Customer A → Part 123 = $18.50
• Customer B → Part 123 = $16.75
• Customer C → Part 123 = $21.00
• Standard customer → Part 123 = $25.00

You don't have to build your pricing around a generic "20% off wholesale" rule.

BigCommerce also has B2B features such as company accounts, payment terms, purchase orders, bulk ordering, etc. The important caveat is that its SKU-level Price Lists are currently an upper-tier feature, rather than something included in the inexpensive entry plans. BigCommerce

bigcommerce.com

2. Shopify — very good, but watch the plan

Shopify's B2B system now has catalogs that control both products and pricing, and catalogs can be assigned directly to individual company locations. Shopify Help Center Shopify Help Center

So you can essentially have:

ABC Supply → ABC catalog → ABC's prices

That's a good model if your customers mostly fall into a few pricing/catalog groups.

The limitation I'd pay attention to is how many unique price lists you need. Shopify's lower plans have catalog limits, while Shopify Plus provides unlimited catalogs and direct company/location assignment. Shopify Help Center

So if you have 5–20 wholesale customers and each has a genuinely different price sheet, I'd lean BigCommerce.

help.shopify.com

3. Adobe Commerce — powerful, probably too much

Adobe Commerce has perhaps the most sophisticated native B2B pricing model here. Its Shared Catalogs let you create custom catalogs and pricing for individual companies, and it supports customer groups, tier pricing, company accounts, quotes, and more. Experience League Experience League

It's excellent if you're eventually going to have:

• hundreds/thousands of customers
• complex company hierarchies
• negotiated pricing
• multiple catalogs
• complicated permissions
• ERP integrations
• sophisticated quoting/workflows

But for a small supplier selling to a few wholesale customers, I'd generally avoid the implementation and maintenance burden unless you already have a Magento/Adobe Commerce setup.

What I'd actually choose

If I were setting up your business today:

BigCommerce + customer-specific Price Lists + customer accounts

would be my starting point.

The key question isn't really "which platform has wholesale pricing?"—several do. It's how you maintain your existing price sheets without creating a nightmare for yourself.

If you tell me roughly how many SKUs you have, how many wholesale customers, whether each customer has a completely different price list, and what you're using for accounting/ERP (QuickBooks, NetSuite, etc.), I can narrow this down to the best 2–3 options for your exact setup.

3. Adobe Commerce — powerful, probably too much

Adobe Commerce has perhaps the most sophisticated native B2B pricing model here. Its Shared Catalogs let you create custom catalogs and pricing for individual companies, and it supports customer groups, tier pricing, company accounts, quotes, and more.

It's excellent if you're eventually going to have:

For a small B2B parts supplier with a handful of wholesale customers, I’d prioritize account-level price lists, customer-specific catalogs, quick reordering, and low admin overhead over a huge enterprise feature set. The best fit usually depends on how complex your pricing is. AFCommerce BigCommerce

Here’s how I’d rank the main options:

Shopify Alkali### My likely recommendation for you

1. BigCommerce B2B Edition — best overall fit

• Create a customer account for each wholesaler.
• Assign each customer (or customer group) their own price list.
• Hide/show products by customer type.
• Support bulk ordering and repeat purchases.
• Avoid building a lot of custom code.

BigCommerceThis is especially attractive if you have things like:

• Customer A gets 15% off Part X
• Customer B has negotiated pricing on 200 SKUs
• Different dealers see different assortments
• Buyers reorder the same parts every month

2. Shopify B2B — best if you want the easiest ecosystem
If you also sell retail/direct-to-consumer, Shopify becomes more compelling because you can run both channels together. Its B2B tools support company accounts, catalogs, and negotiated pricing, though very complex industrial pricing may require additional tooling. Shopify PortalSphere

3. WooCommerce — best if your needs are simple and you have technical help
For example:

• 10–50 wholesale customers
• a few pricing tiers
• mostly repeat orders

It can work well, but you’ll be assembling pieces (customer groups, pricing rules, wholesale ordering, etc.).

What I would avoid

I would not start with an enterprise platform like Adobe Commerce or OroCommerce unless you have:

• thousands of SKUs,
• many sales reps,
• complicated quoting,
• ERP-driven pricing,
• multiple warehouses,
• hundreds/thousands of customers. Alkali

A few questions would change my recommendation:

1. Roughly how many SKUs/parts do you sell?
2. Do your wholesalers each have unique negotiated prices, or just tiers (e.g., dealer/wholesale/distributor)?
3. Do customers need to place orders online themselves, or is the site mainly a catalog/order-entry tool for your sales team?
4. What system currently holds inventory/pricing (QuickBooks, NetSuite, ERP, spreadsheets, etc.)?

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize customer-specific SKU pricing over a generic “wholesale discount” feature.

My ranking

1. BigCommerce — probably my first choice

BigCommerce is particularly well suited to your situation because its B2B functionality lets you create price lists with pricing down to the individual SKU, then assign those price lists to particular customer groups or even individual wholesale accounts. BigCommerce

For example:

• Customer A → Part 123 = $8.50
• Customer B → Part 123 = $9.25
• Customer C → Part 123 = $7.90
• Everyone else → $12.00
• Customer A also gets different prices on 47 other SKUs

That's much closer to how a real parts distributor often operates than simply saying “all wholesale customers get 20% off.”

bigcommerce.com

2. Shopify — very good, but I'd choose it for a different reason

Shopify B2B now has native catalogs that control both which products a customer can see and what they pay. You can assign catalogs to companies/company locations, use fixed product prices, overall percentage adjustments, quantity rules, and volume pricing. Shopify Help Center Shopify Help Center

So it can handle something like:

Acme Wholesale sees 500 parts and has its own negotiated prices.

That's excellent.

The important distinction is that Shopify's B2B model is heavily catalog/company-location oriented. On Plus, you get unlimited catalogs and direct assignment to companies and locations; lower plans have considerably more limited catalog capabilities. Shopify Help Center

For a business with a small number of wholesale customers and a consumer storefront, Shopify could actually be the better overall platform.

3. Adobe Commerce — powerful but probably overkill

Adobe Commerce has exceptionally sophisticated B2B pricing. Its Shared Catalog functionality lets you create custom catalogs with custom prices and make them available only to particular companies. Experience League Experience League

It also supports company accounts, multiple buyers/permissions, quick order, and negotiated quotes. Experience League

I'd consider it if you had hundreds of customers, complicated account structures, multiple websites, ERP integration, or highly complex pricing rules. For a small supplier with a few accounts, the implementation/maintenance burden is probably not worth it.

What I'd do in your shoes

If your situation is roughly:

50–5,000 SKUs + 5–50 wholesale customers + each customer has negotiated pricing + customers reorder parts regularly

I'd shortlist BigCommerce B2B and Shopify B2B.

I'd lean BigCommerce if your business is primarily wholesale and the pricing table is the heart of the operation.

I'd lean Shopify if you're also selling direct-to-consumer and want the easiest modern storefront/admin experience.

One particularly important question is how your pricing actually works. If you tell me something like:

“We have 2,000 SKUs, 12 customers, each customer has their own negotiated price on some/all SKUs, customers log in to reorder, and we need PO numbers/net-30 terms.”

I can tell you which platform I'd pick and what the actual setup would look like, including whether you need Shopify Plus/BigCommerce B2B or can get away with a cheaper plan.

For a small B2B parts supplier with a handful of wholesale accounts, I’d put BigCommerce at the top of the list—especially if each customer has negotiated SKU-level pricing.

My ranking

BigCommerce has native price lists that can be assigned to individual wholesale accounts or customer groups, with pricing customized down to the individual SKU. BigCommerce BigCommerce

That maps very nicely to a situation like:

• Customer A → Part 123 = $18.50
• Customer B → Part 123 = $17.25
• Customer C → Part 123 = $19.10
• All other customers → $22.00

You can also give different customers different product assortments, reorder functionality, and B2B purchasing workflows. BigCommerce BigCommerce

Where Adobe Commerce wins

Adobe Commerce has arguably the most sophisticated native pricing model. Its B2B Shared Catalogs let you create a catalog with custom products and prices specifically for a company, and you can combine that with customer-group and quantity/tier pricing. Experience League Experience League

The downside is that it's substantially more platform than a small supplier typically needs.

Shopify is also viable

Shopify now has native B2B catalogs with custom pricing, product availability, volume pricing, and quantity rules. Shopify Plus allows unlimited catalogs and assignment at the company-location level. Shopify Help Center

So I'd choose Shopify if you also care heavily about consumer-grade storefront UX, integrations, and the broader Shopify ecosystem. For a primarily wholesale parts business, though, I think BigCommerce's pricing/account model is a more natural fit.

What I'd choose for your business

BigCommerce B2B would be my first choice if your requirements are roughly:

"I have 10–100 wholesale customers, each may have their own negotiated prices, and I want customers to log in and automatically see their prices."

You probably don't need an enterprise-grade Adobe implementation.

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has a completely different price list vs. a discount off a common list, I can narrow this down to the best setup—and tell you whether BigCommerce, Shopify, or WooCommerce would actually be cheapest/easiest for your situation.

For a small B2B parts supplier with a handful of wholesale accounts, I’d put BigCommerce first, with Shopify second.

My ranking

1. BigCommerce — best for your use case

BigCommerce is particularly strong if your wholesale customers each have their own negotiated price list.

Its B2B functionality supports:

• Customer-specific pricing down to the individual SKU
• Assigning different price lists to individual wholesale accounts
• Customer groups with different products/prices
• Customer-specific catalogs
• Company accounts and buyer permissions
• Reordering, quotes, invoices and other B2B workflows

BigCommerce explicitly describes its price lists as allowing prices and discounts to be customized down to the unique SKU for an individual client. BigCommerce BigCommerce

That's a very good match for a parts business where, for example:

Customer A pays $18.50 for Part X
Customer B pays $21.00
Customer C pays $17.25
Everyone else sees $25.00

You don't have to turn every negotiated price into a complicated discount rule.

bigcommerce.com

2. Shopify — surprisingly good now

Shopify has become much more interesting for B2B in 2026. Shopify recently brought core B2B functionality to its Basic, Grow and Advanced plans, including up to three custom catalogs, tailored pricing, volume pricing, quantity rules, payment terms and company profiles. Shopify

The catch is that customer-by-customer pricing is considerably better on Shopify Plus. Plus gives you unlimited catalogs and lets you assign catalogs directly to individual company locations. Shopify Help Center Shopify Help Center

So if you have only a few customers and can organize them into a handful of pricing tiers, regular Shopify could be excellent.

If every customer has a unique negotiated price for hundreds/thousands of parts, I'd favor BigCommerce.

shopify.com

3. Adobe Commerce

Adobe Commerce can handle sophisticated customer-group pricing and B2B catalogs extremely well. Experience League

But for a small supplier with a few wholesale accounts, I'd consider it overkill unless you have unusual pricing logic, ERP integration, multiple storefronts, or a very large catalog.

What I'd choose for you

If your situation is roughly:

• 5–50 wholesale customers
• Thousands of parts/SKUs
• Each customer has negotiated prices
• Customers should log in and see their prices
• Customers reorder the same parts frequently
• You don't need a huge consumer-facing storefront

I'd start with BigCommerce B2B.

If it's more like:

• 5–10 customers
• Mostly the same products/pricing
• A few wholesale discount tiers
• You want the easiest platform to administer
• You may also sell retail/DTC

I'd seriously consider Shopify.

The important question is how your pricing actually works. If you tell me something like “we have 2,000 SKUs, 12 wholesale customers, and each customer has a different discount/price on roughly 300 SKUs”, I can tell you which platform will be least painful and how I'd structure the pricing.

The catch is that customer-by-customer pricing is considerably better on Shopify Plus. Plus gives you unlimited catalogs and lets you assign catalogs directly to individual company locations. Shopify Help Center Shopify Help Center

So if you have only a few customers and can organize them into a handful of pricing tiers, regular Shopify could be excellent.

3. Adobe Commerce

Adobe Commerce can handle sophisticated customer-group pricing and B2B catalogs extremely well.

But for a small supplier with a few wholesale accounts, I'd consider it overkill unless you have unusual pricing logic, ERP integration, multiple storefronts, or a very large catalog.

What I'd choose for you

If your situation is roughly:

For a small B2B parts supplier with a handful of wholesale customers, customer-specific pricing should be one of the deciding factors. You don't necessarily need a heavyweight enterprise platform.

My shortlist

1. BigCommerce — probably my first choice

BigCommerce is particularly well suited to your situation. Its B2B functionality lets you create price lists that can be assigned to individual wholesale accounts or customer groups, including prices down to the individual SKU. BigCommerce BigCommerce

For example:

• Customer A → Part #123 = $18.50
• Customer B → Part #123 = $21.00
• Customer C → Part #123 = $16.75
• Everyone else → $29.95

You can also have customer-specific catalogs, payment methods, credit limits, reordering, etc. BigCommerce BigCommerce

Why I'd lean this way: it handles the awkward B2B stuff without requiring you to bolt together a bunch of plugins.

bigcommerce.com

2. WooCommerce — excellent if keeping costs down matters

WooCommerce can do extremely flexible customer-specific pricing, but you'll generally use a B2B extension/plugin rather than getting everything from the core platform.

Its B2B pricing functionality supports custom prices for customer groups, quantity pricing, tax exemptions, product/category rules, and hiding prices from non-approved customers. WooCommerce

There are also extensions that support pricing for individual customers, rather than just broad customer groups. WooCommerce

I'd choose WooCommerce if you already use WordPress or have someone comfortable maintaining it.

woocommerce.com

3. Shopify — easiest to operate, but I'd scrutinize the pricing model

Shopify now has native B2B catalogs and pricing. You can assign catalogs to companies/company locations and specify products and prices for those customers. Shopify Plus removes the catalog limits and allows direct assignment to companies and locations. Shopify Help Center

The catch is that your use case sounds more like negotiated account-level pricing than conventional wholesale tiers. I'd therefore make Shopify prove that its current catalog setup handles your exact pricing matrix before choosing it.

4. Adobe Commerce — great, but likely too much

Adobe Commerce has very sophisticated customer-group and shared-catalog pricing. Its B2B functionality specifically supports custom pricing for different companies. Experience League

But for "we have a few wholesale customers and need their negotiated prices online," I'd consider it excessive unless you have unusually complex ERP, catalog, workflow, or account requirements.

What I'd choose for your business

BigCommerce if you're starting from scratch.

WooCommerce if you already have WordPress or want maximum flexibility at relatively low cost.

Shopify if ease of administration is more important than having the most natural B2B pricing architecture.

The key question I'd use to narrow it down is how you currently maintain prices. If you have something like a spreadsheet with 5–20 wholesale customers and each customer has hundreds/thousands of negotiated part prices, I can compare BigCommerce vs WooCommerce vs Shopify specifically for importing/managing those customer-specific price lists. That's where the differences become much more important.

For a small B2B parts supplier with a handful of wholesale accounts, I’d put BigCommerce first, especially if each customer has negotiated prices on individual SKUs.

My ranking

1. BigCommerce — my pick

BigCommerce has a particularly good model for wholesale: Customer Groups + Price Lists.

You can have, for example:

• Customer A → 15% off most parts, but negotiated prices on 30 specific SKUs
• Customer B → completely different prices
• Customer C → same prices as A but different product availability
• Standard web customer → normal retail pricing

Its price lists can set prices down to the individual SKU/variant, and can be assigned to particular customer groups/accounts. BigCommerce BigCommerce

That's a very natural fit for a parts distributor where your pricing is essentially:

Customer × SKU = negotiated price

BigCommerce also has B2B features for company accounts, quotes, purchasing controls, buyer portals, etc., if you eventually need them. BigCommerce

And there's a useful real-world example: VIP Supply Co. uses 302 customer groups and 219 customer-specific price lists for more than 500 companies. BigCommerce

bigcommerce.com

2. Shopify Plus — very good, but I'd hesitate for your size

Shopify's B2B catalogs let you specify products and prices for particular companies/company locations, including fixed prices for individual products. Shopify Help Center Shopify Help Center

The catch is that direct company/location catalog assignment and unlimited catalogs are Plus features. Shopify Help Center

So if you're only serving a few wholesale customers, I wouldn't choose Shopify Plus just to solve customer-specific pricing. You're potentially paying for a much larger platform than you need.

help.shopify.com

3. Adobe Commerce

Adobe Commerce can handle sophisticated B2B pricing through Shared Catalogs, including custom pricing for individual companies. Experience League

It's an excellent choice if you're eventually dealing with things like complex company hierarchies, massive catalogs, sophisticated ERP integration, quoting, sales reps, and highly customized workflows.

For "we have 5–20 wholesale customers and each has its own price sheet," though, I'd consider it unnecessarily heavy.

What I'd actually do in your situation

I'd seriously consider:

BigCommerce + customer groups + SKU-level price lists

That gives you a relatively clean structure:

Products
   ↓
Default price
   ↓
Customer Group
   ↓
Customer-specific Price List
   ↓
Wholesale customer's login
   ↓
Their negotiated prices automatically appear

The important question is how complicated your pricing really is. If you tell me roughly:

1. number of SKUs,
2. number of wholesale customers,
3. whether every customer has a different price for every SKU or only negotiated prices on some,
4. whether customers need POs / net-30 terms, and
5. what you're using for inventory/accounting (QuickBooks, NetSuite, Fishbowl, ERP, etc.),

I can narrow this down to the cheapest/simplest setup I'd use for your business, including whether you actually need BigCommerce B2B Edition or just the regular platform.

I can narrow this down to the cheapest/simplest setup I'd use for your business, including whether you actually need BigCommerce B2B Edition or just the regular platform.

For a small B2B parts supplier with a handful of wholesale customers, I’d focus less on “B2B ecommerce” broadly and more on how cleanly the platform handles negotiated, customer-by-customer SKU pricing.

My ranking

BigCommerce is probably the one I'd investigate first. Its B2B functionality has native price lists that can customize pricing down to the individual SKU and assign those prices to individual wholesale accounts or customer groups. www.bigcommerce.comdocs.bigcommerce.com

That's a particularly good model for parts distribution. For example:

• Customer A → SKU 123 → $8.40
• Customer B → SKU 123 → $7.95
• Customer C → SKU 123 → $9.10
• Customer A → SKU 456 → $14.25
• Everyone else → standard price

You can also combine customer-specific pricing with customer groups, catalogs, quantity breaks, and B2B purchasing workflows. docs.bigcommerce.com

Shopify is a very close second

Shopify B2B has gotten considerably better for this use case. Its B2B catalogs allow you to assign products and pricing to particular companies/company locations, including fixed prices and volume pricing. help.shopify.com

The catch is that the exact pricing behavior matters. For example, when multiple catalogs apply to a company, Shopify has rules around which price wins; you don't want to accidentally create overlapping catalogs and expose a lower price than intended. help.shopify.com

For your business, I'd choose based on this

Pick BigCommerce if:

• You have 5–100-ish wholesale accounts.
• Pricing is negotiated per customer and/or per SKU.
• You sell lots of parts/SKUs.
• Customers need login-based pricing.
• You want B2B functionality without building a custom system.

Pick Shopify if:

• You also want a strong consumer/DTC storefront.
• Your pricing can mostly be organized into catalogs/customer tiers.
• Ease of administration and the Shopify ecosystem are priorities.
• You expect to add other sales channels later.

Don't start with Adobe Commerce unless you already have substantial operational complexity. It is powerful—shared catalogs, company structures, quote workflows, etc.—but it's generally overkill for a small supplier. www.shopify.com

One thing I'd check before choosing

For a parts supplier, customer-specific pricing isn't the only important question. I'd specifically test these five scenarios in a demo:

1. Customer A gets a unique price for 300 individual SKUs
2. Customer B gets a different price on those same SKUs
3. New SKU → automatically gets Customer B's standard discount
4. Customer A has a special negotiated price on just 10 SKUs
5. Customer logs in → sees only their price, not MSRP/another customer's price

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has a mostly unique price list or just a discount percentage (e.g. “20% off list”), I can tell you which platform I'd pick and what the simplest setup would be.

For a small B2B parts supplier with a handful of wholesale customers, I’d prioritize customer-specific price lists, account-level catalogs, and easy reordering over the heavier enterprise B2B platforms.

My shortlist

1. BigCommerce — probably the best fit

BigCommerce is particularly strong here because its price lists can set prices down to the individual SKU and assign them to specific customer groups or individual wholesale accounts. Its company accounts can also be associated with those customer groups. BigCommerce BigCommerce

So you could have:

• Customer A → their negotiated price list
• Customer B → a different price list
• Customer C → another price list
• New wholesale customer → standard wholesale pricing

And the customer sees the appropriate prices after logging in.

For a parts business, that's a very natural model. You don't have to create a separate storefront for every customer.

bigcommerce.com

2. Shopify — excellent if simplicity matters

Shopify has substantially improved its native B2B functionality in 2026. Even non-Plus plans now have company profiles, custom catalogs, tailored pricing, volume discounts, quantity rules and payment terms; Plus removes the catalog limitations and allows unlimited catalogs with direct assignment to companies/locations. Shopify Help Center Shopify

So if you have, say, 10–50 wholesale accounts with relatively straightforward negotiated pricing, Shopify could be the easiest system to operate.

The distinction I'd make is:

BigCommerce: "We're primarily a B2B distributor and need sophisticated pricing."

Shopify: "We're a straightforward wholesale business and want the easiest overall ecommerce platform."

shopify.com

What I'd choose for a parts supplier

If your pricing looks something like:

SKU 123 → Customer A pays $14.20, Customer B pays $12.80, Customer C pays $15.10

I'd lean BigCommerce.

If it looks more like:

All wholesale customers get 20% off, with occasional special prices

I'd lean Shopify.

If pricing is actually calculated from a complicated ERP/customer contract—e.g. customer + quantity + manufacturer + region + contract + current cost—you should look at something more B2B-specific. SAP Commerce, for example, supports negotiated customer pricing at multiple organizational levels and can retrieve pricing directly from an ERP backend. SAP Help Portal SAP Help Portal

One thing I'd investigate before choosing

For your business, the ERP/accounting system may matter more than the storefront.

If you tell me:

1. roughly how many SKUs you have,
2. how many wholesale customers,
3. what you're using for inventory/accounting today (QuickBooks, NetSuite, SAP, etc.), and
4. whether each customer has a completely different price for each part or just different discount tiers,

I can narrow this down to the 2–3 platforms I'd actually consider, including approximate cost and how I'd structure the customer pricing.

My ranking

Why I'd lean BigCommerce

BigCommerce has a particularly good pricing model for your situation. Its Price Lists can set prices down to the individual SKU and can be assigned either to a customer group or to a single wholesale account. BigCommerce BigCommerce

So you could have something like:

• Customer A → their negotiated price list
• Customer B → a different price list
• Customer C → another negotiated list
• New wholesale customer → standard wholesale pricing
• Retail visitor → normal retail price

The important distinction is that you're not forced into simply saying "all wholesale customers get 30% off." You can maintain actual negotiated prices per SKU, which is often what parts/distribution businesses need.

It also supports customer groups, volume pricing, reordering and other wholesale-oriented workflows. BigCommerce

Shopify is good, but I'd choose it for a different reason

shopify.com has substantially improved its native B2B capabilities. Its B2B catalogs let you specify products and prices for particular companies/company locations, and it supports volume pricing and purchasing rules. Shopify Help Center Shopify

I'd choose Shopify if you also want a really strong consumer-facing storefront/brand site and B2B is one part of the business.

For a pure parts wholesaler, though, BigCommerce's pricing architecture feels more naturally aligned with the problem.

One important question

The answer changes quite a bit depending on how your pricing works.

If you mean:

"Customer A gets $12.40 for SKU 123, Customer B gets $11.75, Customer C gets $13.10, and these prices are negotiated individually."

BigCommerce is very compelling.

If instead it's:

"Customer A gets 20% off, Customer B gets 25% off, and large orders get additional quantity breaks."

Then Shopify, BigCommerce, and even WooCommerce can all handle it fairly well.

And if you have an existing ERP/accounting system containing the customer-specific prices, I'd prioritize the ecommerce platform's integration capabilities over the storefront itself.

If you tell me (1) roughly how many SKUs you have, (2) how many wholesale customers, (3) whether every customer has different SKU prices, and (4) what accounting/ERP system you use, I can narrow this down to the best 2–3 options for your exact setup.

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize customer-specific SKU pricing, customer-specific product visibility, and easy administration over a huge enterprise feature set.

My shortlist

1. BigCommerce — my first choice for your situation

BigCommerce has native Price Lists that can assign different SKU-level prices to customer groups, and its B2B offering specifically supports assigning price lists to individual wholesale accounts. docs.bigcommerce.com

That maps very well to something like:

• Customer A → Part 123 = $8.40
• Customer B → Part 123 = $7.95
• Customer C → Part 123 = $9.10
• Everyone else → $11.50

You can also maintain different product availability and customer groups without building the whole thing around custom development.

BigCommerce B2B wholesale overview

2. Shopify — probably the easiest to operate

Shopify has significantly improved its native B2B capabilities in 2026. Basic/Grow/Advanced now include B2B catalogs, with up to three active catalogs, while Plus allows unlimited catalogs and direct assignment to companies/company locations. help.shopify.com

That's attractive if you have, say, 5–20 wholesale customers with relatively straightforward pricing tiers. The downside is that if every customer needs a genuinely unique price book, BigCommerce's price-list model is more naturally suited to that.

Shopify B2B

3. Adobe Commerce — extremely powerful, but probably overkill

Adobe Commerce B2B has perhaps the strongest native model for complicated wholesale businesses: custom shared catalogs can have custom prices for individual companies, along with product/category visibility and company accounts. experienceleague.adobe.com

I'd consider it if you have hundreds/thousands of customers, complicated contracts, multiple price structures, ERP integration, negotiated quotes, etc. For "a few wholesale customers," I'd generally avoid the additional complexity.

What I'd choose

For a small parts supplier with a few wholesale accounts, I'd rank them:

BigCommerce > Shopify > Adobe Commerce

The key question, though, is how your pricing actually works. If you tell me something like:

"I have 8 customers, each gets their own negotiated price on 200–500 SKUs, plus quantity breaks, and they currently order by email."

I can tell you which platform I'd use, what it would cost roughly, and how I'd structure the customer/price lists.

For your situation—small B2B parts supplier, a handful of wholesale accounts, and customer-specific negotiated pricing—I’d shortlist BigCommerce and Shopify, with BigCommerce B2B Edition probably the better fit.

My ranking

Why I'd lean BigCommerce: its B2B system has price lists that can go down to individual SKUs, and those price lists can be assigned to individual wholesale accounts or groups. Customers can therefore log in and see their prices without creating duplicate products or relying on discount codes. www.bigcommerce.com

That's particularly well suited to parts distribution. For example:

• Customer A → $8.42 for Part #123
• Customer B → $7.95 for Part #123
• Customer C → $7.25 for Part #123
• Everyone else → $11.99

You can maintain those as customer/company pricing rather than creating four versions of the product.

BigCommerce also supports company accounts, buyer permissions, customer groups, catalogs, bulk pricing, and B2B ordering workflows. docs.bigcommerce.com

Shopify is a very close second

Shopify B2B now has company-specific catalogs and price lists, including pricing at the company/location level, so it absolutely can handle your use case. www.shopify.com

I'd pick Shopify instead if you also care heavily about:

• a polished consumer-facing storefront
• Shopify POS
• marketing/SEO ecosystem
• lots of third-party integrations
• potentially expanding from wholesale into DTC

One caveat: Shopify's more advanced B2B capabilities are increasingly tied to its higher-tier offerings, whereas BigCommerce is more naturally oriented around B2B functionality. Shopify's current published Plus pricing starts around $2,300/month on a 3-year term. www.shopify.com

For a small parts supplier, I'd actually evaluate one thing before choosing

How many unique prices do you have?

If you have, say, 10 wholesale customers × 2,000 SKUs, and every customer has a negotiated price on most products, that's a very different requirement from:

"We have 5 wholesale tiers and most customers fall into one of them."

BigCommerce is particularly attractive for the first scenario because of its SKU-level price lists. www.bigcommerce.com

If you tell me (1) roughly how many SKUs you have, (2) how many wholesale customers, (3) whether each customer has unique pricing or pricing tiers, and (4) what accounting/ERP system you use, I can narrow this down to the best 2–3 options and tell you what I'd choose.

For a small B2B parts supplier selling to a handful of wholesale customers, I’d prioritize platforms that can do account-level price lists, customer groups, hidden catalogs, and easy reordering without forcing you into an enterprise implementation.

My shortlist:

www.bigcommerce.comwww.shopify.com

My likely recommendation for your situation

1. BigCommerce B2B Edition — best overall fit if pricing complexity matters

• Create a customer account for each wholesaler
• Assign each account a custom price list
• Give different customers different discounts by SKU
• Support wholesale catalogs and account-specific buying experiences

BigCommerce specifically supports customer groups and SKU-level price lists, which maps well to parts suppliers where Customer A might pay different contract pricing than Customer B. www.bigcommerce.com

2. WooCommerce — best if you have only a few wholesale accounts
If you have, say:

• 10–50 wholesale customers
• a few thousand SKUs
• someone comfortable managing WordPress

…it can be very cost-effective. You can add wholesale pricing plugins and customize almost anything, but you’ll own more of the maintenance burden. www.afcommerce.com

3. Shopify — best if you want wholesale + consumer sales
If you sell parts both to businesses and directly to consumers, Shopify becomes more attractive. Its B2B tools support things like company profiles, custom catalogs, and pricing, but many advanced wholesale scenarios are aimed at higher-tier Shopify plans. www.bigcommerce.comwww.shopify.com

Features I’d consider mandatory for a parts supplier

Whatever you choose, make sure it handles:

• Customer-specific price lists (not just coupon codes)
• Contract pricing by SKU
• Customer login before showing prices
• Quick order / SKU entry
• Saved reorder lists
• Multiple ship-to addresses
• Minimum quantities or case packs
• ERP/accounting integration (if you use one)
• Quote requests for unusual orders

For a small supplier with a few wholesale customers, I’d probably choose:

• BigCommerce if your negotiated pricing is central to the business
• WooCommerce if keeping costs low matters most
• Shopify if you expect a mixed wholesale + retail model

A few details would change the recommendation: roughly how many SKUs do you carry, how many wholesale customers need unique pricing, and are your prices maintained in an ERP/accounting system (QuickBooks, NetSuite, Epicor, etc.)?

For a small B2B parts supplier with a handful of wholesale customers, I’d prioritize customer-specific price lists, account logins, quick reordering, and low admin overhead over general ecommerce features.

My shortlist:

www.bigcommerce.comwww.shopify.com

For your situation, I’d rank them:

1. BigCommerce — likely the best overall fit

If you have, for example:

• Customer A gets 15% off all bearings
• Customer B has negotiated prices on 200 SKUs
• Customer C sees only certain product categories
• Each customer needs their own reorder history

BigCommerce handles this kind of setup more naturally. Its B2B functionality includes customer groups and price lists that can be assigned to specific accounts or groups. www.bigcommerce.com

2. WooCommerce — best if you are very small and technical

If you have only 5–20 wholesale accounts and orders are still partly handled by phone/email, WooCommerce can work well. You can add wholesale pricing plugins and keep costs down. The tradeoff is that you’ll be managing more pieces yourself.

3. Shopify — best if you might add online retail later

Shopify’s B2B tools are much better than they used to be: company accounts, custom pricing, catalogs, and payment terms are supported. www.bigcommerce.comwww.shopify.com But for a pure distributor workflow, you may find yourself paying for features designed around a larger operation.

A few questions would change the recommendation:

1. How many wholesale customers do you expect in 2 years (10, 100, 1,000+)?
2. Are prices negotiated per customer, or are they mostly customer tiers (dealer/distributor levels)?
3. Do you need integration with inventory/accounting software (QuickBooks, NetSuite, Epicor, etc.)?
4. Do customers need to see stock levels and place repeat orders themselves?

For a small B2B parts supplier with a handful of wholesale accounts, I’d put BigCommerce first, especially if each customer has negotiated SKU-level pricing.

My ranking

Why BigCommerce stands out: its native Customer Groups + Price Lists model is almost exactly what you described. Price Lists can specify prices at the variant/SKU level and be assigned to customer groups; BigCommerce also supports assigning pricing structures to individual company accounts. docs.bigcommerce.com

So you could have, for example:

• Customer A → 12,000 SKUs with their negotiated prices
• Customer B → a different price list
• Customer C → standard wholesale pricing
• Retail/customer → normal website pricing

Customers log in and automatically see their prices, rather than you having to rely on coupon codes or manual order adjustments. BigCommerce specifically describes its wholesale functionality as supporting unique SKU-level pricing for individual clients. www.bigcommerce.com

BigCommerce B2B/Wholesale

Shopify is worth considering

Shopify has gotten considerably better for B2B. As of 2026, its Basic/Grow/Advanced plans include B2B catalogs, companies, payment terms, volume pricing, etc. However, directly assigning a unique catalog to an individual company/location requires Shopify Plus; the lower plans are limited to three active catalogs across B2B markets. help.shopify.com

So if your pricing is mostly:

"Wholesale customers get 25% off"

Shopify is attractive.

If it's:

"Customer A pays $14.27 for SKU 1234, $8.91 for SKU 5678, while Customer B pays completely different negotiated prices"

I'd favor BigCommerce.

Shopify B2B pricing/catalogs

Adobe Commerce

Adobe Commerce has arguably the deepest native B2B pricing model: shared catalogs with custom prices for different companies, customer groups, tier pricing, quotes, and more. experienceleague.adobe.com

But for a small supplier with only a few wholesale accounts, I'd consider it overkill unless your pricing/catalog/ERP requirements are unusually complicated.

What I'd choose for your situation

BigCommerce + customer-specific Price Lists would be my starting point.

The important question isn't really how many customers you have—it's how complicated the pricing is. If you tell me roughly:

1. number of SKUs,
2. number of wholesale customers,
3. whether every customer has different prices or you have 3–5 pricing tiers,
4. whether you need an ERP/accounting integration (QuickBooks, NetSuite, Sage, etc.), and
5. whether you also sell to consumers,

I can narrow it down to BigCommerce vs Shopify vs WooCommerce for your particular operation.

For a small B2B parts supplier with a handful of wholesale customers, the “best” ecommerce platform is usually the one that handles account-level pricing, customer groups, and negotiated catalogs without forcing you into an expensive enterprise build.

My shortlist:

www.bigcommerce.com

My likely recommendation for your situation

1. BigCommerce B2B Edition — best overall fit if wholesale is your main business

• Create a login for each customer.
• Assign each account its own pricing.
• Show different SKUs or catalogs by customer.
• Support bulk ordering and reorders.
• Avoid building custom pricing logic.

BigCommerce specifically supports customer groups and price lists that can be assigned to individual wholesale accounts or groups. www.bigcommerce.com

2. Shopify + B2B features — best if you also want a consumer-facing store
If you sell some parts retail or plan to build a brand site, Shopify is attractive. But for pure wholesale, you may end up adding apps or moving to Shopify Plus for more sophisticated workflows. www.bigcommerce.com

3. WooCommerce — best budget option
If you have:

• 20–200 wholesale customers
• simple negotiated pricing
• a technically capable person maintaining the site

WooCommerce can work well with B2B extensions. It is usually cheaper but less “set it and forget it.”

Features I’d prioritize for a parts supplier

Before choosing, make sure it supports:

• Customer-specific price lists (Customer A sees $8.50; Customer B sees $7.90)
• Contract pricing by SKU
• Quick order forms (part number entry is huge for B2B)
• CSV price updates
• Customer-specific catalogs
• Reorder lists
• Net terms / invoice workflows
• ERP/accounting integration if you use something like QuickBooks, NetSuite, Epicor, etc.

For a small supplier with only a few wholesale accounts, I would avoid Adobe Commerce unless your pricing rules are unusually complex. I’d usually choose BigCommerce if wholesale is the core business, or Shopify if you want wholesale + retail together. www.bigcommerce.com

A couple of details would change the recommendation:

1. Roughly how many SKUs/parts do you carry?
2. Do your customers each have negotiated prices by part number, or mostly a discount like “20% off everything”?
3. Are you currently using an ERP/accounting system (QuickBooks, NetSuite, Sage, Epicor, etc.)?

For a small B2B parts supplier with a handful of wholesale accounts, I’d prioritize platforms that make account-specific price lists a first-class feature rather than relying on apps.

My shortlist

For your particular situation, I'd lean toward BigCommerce or Shopify Plus rather than Adobe Commerce.

If pricing is the main thing

Adobe Commerce is arguably the strongest. Its B2B "Shared Catalogs" let you create custom catalogs with custom prices and assign them to specific companies. You can set individual fixed prices, percentage discounts, and quantity-based tier pricing. experienceleague.adobe.com

That's a very natural model for, say:

• Customer A → 15% off everything
• Customer B → negotiated prices on 75 specific SKUs
• Customer C → completely different prices + only sees certain parts
• Customer D → standard wholesale pricing + quantity breaks

The downside is complexity and cost. Adobe Commerce is powerful enough that it can be overkill for a small supplier.

Shopify Plus

Shopify's B2B system is particularly attractive if you want something easy for a small team to administer. Catalogs control both product availability and pricing, and on Plus you can have unlimited catalogs and assign them directly to companies/company locations. It also supports quantity rules and volume pricing. help.shopify.com

So you could have:

ABC Supply: catalog A → negotiated prices
XYZ Wholesale: catalog B → negotiated prices
Everyone else: catalog C → normal pricing

The catch is that Shopify Plus is a fairly substantial platform commitment. If you only have a few wholesale customers, I'd want to make sure the rest of the Shopify ecosystem is valuable to you too.

BigCommerce

I'd put BigCommerce B2B very high on the list for a parts distributor. It's worth evaluating if your business is more traditional wholesale/distribution than consumer retail.

What I'd choose

If I were setting this up for a small parts supplier:

1. BigCommerce — probably my first platform to investigate
2. Shopify Plus — best if ease of use and broader ecommerce capabilities matter
3. Adobe Commerce — best if pricing/catalog rules are unusually complicated
4. WooCommerce — attractive if keeping costs/control high is more important than having turnkey B2B functionality

One important distinction: "customer-specific pricing" can mean two very different things. If you mean each wholesale account has its own negotiated price for individual SKUs, rather than simply "Customer A gets 20% off," I'd evaluate the platforms specifically around SKU-level price lists, price imports, customer groups, quantity breaks, and ERP integration.

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether prices are negotiated per-SKU or mostly percentage discounts, I can narrow this to the best 1–2 options for your business.

For a small B2B parts supplier with a handful of wholesale accounts, I’d put BigCommerce first, Shopify second, and Adobe Commerce/Magento third.

My ranking for your situation

BigCommerce is probably the sweet spot for you. Its B2B functionality has native price lists that can be assigned to individual wholesale accounts or customer groups, down to the SKU level. It also supports bulk pricing and customer-specific catalogs. www.bigcommerce.com

So you could have, for example:

• Customer A → SKU 123 = $8.40
• Customer B → SKU 123 = $7.95
• Customer C → SKU 123 = $9.10
• General website price → $12.00

…and the appropriate logged-in customer sees their negotiated price.

Shopify

Shopify is also quite good now. Its B2B catalogs let you customize products and pricing for specific companies, and Shopify Plus allows unlimited catalogs and direct assignment to company locations. help.shopify.com

The catch is that I'd choose Shopify mainly if you also care about having the broader Shopify ecosystem, integrations, polished storefront, etc. For a parts/wholesale-first business where pricing is the central issue, BigCommerce feels more naturally aligned.

Adobe Commerce

Adobe Commerce is arguably the most powerful of the three for this particular requirement. Its B2B Shared Catalogs are explicitly designed to provide custom pricing for different companies, and you can have company-specific catalogs, customer groups, tier pricing, quotes, and company accounts. experienceleague.adobe.com

But for only a few wholesale customers, I'd consider it overkill unless your pricing rules are unusually complicated.

The key question I'd use to choose

If your pricing looks like:

"Each wholesale customer has an agreed price for some/all SKUs, and they log in and place orders"

→ BigCommerce B2B.

If it's:

"We have 5–10 customers, each with hundreds/thousands of negotiated SKU prices, plus quantity breaks"

→ BigCommerce becomes an especially strong choice.

If it's:

"Every customer has a completely different catalog, contract pricing, quotes, approval workflows, multiple buyers, ERP integration, etc."

→ Adobe Commerce starts making more sense.

If you tell me roughly how many SKUs you have, how many wholesale customers, and whether each customer has a completely different price list or mostly a % discount, I can narrow it down considerably—and tell you what I'd actually deploy in your shoes.

For your situation—small B2B parts supplier, a handful of wholesale accounts, and negotiated customer-by-customer pricing—I’d narrow it to BigCommerce vs. Shopify.

My pick: BigCommerce

BigCommerce is probably the better fit if customer-specific pricing is the main requirement.

Its native Price Lists let you override pricing down to the SKU/variant level and assign those prices to customer groups. You can also have different price lists for different customers, while customers without an override fall back to the normal catalog price. docs.bigcommerce.comdocs.bigcommerce.comwww.shopify.com

That maps nicely to something like:

You can also maintain shared pricing groups when several customers have the same deal, rather than creating everything individually. BigCommerce supports assigning companies to customer groups and using those groups to control pricing/catalog access. docs.bigcommerce.com

Shopify is also quite good now

Shopify has improved substantially for B2B. As of 2026, even its non-Plus plans include B2B functionality with company profiles, custom catalogs, tailored pricing, volume discounts and payment terms. Shopify says Plus adds unlimited catalogs and direct catalog assignment to companies/locations. www.shopify.com

So I'd think about it this way:

BigCommerce

• ⭐ Best fit for complex wholesale pricing
• Customer/group-specific price lists
• SKU-level pricing
• Strong B2B account structure
• Good if you expect lots of negotiated prices
• Particularly attractive for parts/industrial-style catalogs

Shopify

• ⭐ Best if you want the easiest overall ecommerce platform
• B2B pricing is now native rather than requiring an app
• Excellent general storefront/admin experience
• Especially compelling if you also sell DTC
• More complex B2B pricing may push you toward Shopify Plus or apps

One important distinction

If by "customer-specific pricing" you mean each wholesale customer literally has their own negotiated price for hundreds/thousands of parts, rather than simply:

Customer A = 20% off
Customer B = 25% off

then I'd choose BigCommerce. Its price-list model is particularly well suited to maintaining actual customer-specific SKU prices. docs.bigcommerce.com

If you tell me roughly how many SKUs you have, how many wholesale customers, whether each customer has unique prices, and whether you need Net-30/POs, I can tell you which platform I'd choose for your specific setup—and whether you actually need a full B2B platform or can keep it much simpler.

For a small B2B parts supplier with a handful of wholesale customers, I’d focus less on generic ecommerce features and more on how easily you can maintain customer-specific SKU prices, catalogs, and ordering rules.

My shortlist

I'd probably choose BigCommerce for your situation. Its B2B functionality specifically supports customer groups, price lists with SKU-level custom pricing, and bulk pricing, without requiring a separate site for wholesale customers. www.bigcommerce.com

For example, you could have:

• Customer A → $8.25 for Part 123
• Customer B → $7.90 for Part 123
• Customer C → $9.10 for Part 123
• Default web price → $11.50

…and have those prices automatically appear when the appropriate customer logs in.

Shopify is also very good

Shopify's B2B catalogs let you assign products and prices to specific companies/company locations, including fixed SKU/variant prices and volume pricing. On Shopify Plus, you get unlimited catalogs and direct assignment to companies and locations. help.shopify.com

I'd favor Shopify Plus if you also care heavily about having a consumer-quality storefront, marketing ecosystem, and broader Shopify integrations.

The catch is that if your business is primarily "customers log in, find parts, see their price, and reorder," BigCommerce's B2B model feels more naturally aligned with that use case.

Adobe Commerce is the power-user option

Adobe Commerce B2B has perhaps the most explicit model for your situation: shared catalogs can be created specifically for individual companies, with custom prices visible only to those companies' logged-in users. experienceleague.adobe.com

It also supports customer-group and quantity/tier pricing. experienceleague.adobe.com

But for "a few wholesale customers," I'd hesitate to take on Adobe Commerce unless you have more complicated requirements—ERP integration, thousands of customer-specific prices, multiple buyer accounts, approval workflows, quotes, etc.

What I'd pick for you

1. BigCommerce B2B — best starting point
2. Shopify Plus B2B — best if you want a more mainstream/polished ecommerce ecosystem
3. Adobe Commerce — best if your B2B pricing is genuinely complex

One important question could change my recommendation: are your customers each getting thousands of individually negotiated SKU prices, or is it more like "Customer A gets 20% off our standard price, Customer B gets 25%, plus some special prices on certain parts"?

If you tell me which of those describes your pricing—and roughly how many SKUs and wholesale customers you have—I can narrow it down considerably.

For a small B2B parts supplier with a few wholesale customers, I’d prioritize platforms that can handle:

• customer-specific price books (“Customer A pays $8, Customer B pays $7.25”)
• customer login portals
• hidden wholesale pricing
• different catalogs by customer
• quick reordering by SKU
• minimum quantities / case packs
• integration with inventory/accounting software

The best fit depends on how complex your pricing is:

www.bigcommerce.comoroinc.com

My likely recommendation for your situation

1. BigCommerce B2B Edition — best overall match

For a parts supplier selling to several wholesale accounts, this is probably the strongest balance of capability and simplicity. It supports customer groups, price lists, account-specific pricing, and custom catalogs without building everything from scratch. www.bigcommerce.com

Example:

• Customer A logs in → sees their negotiated prices
• Customer B logs in → sees different prices
• Public visitors → see retail or no prices

2. Shopify (with B2B features/apps) — best if you already like Shopify

If you also sell direct-to-consumer, Shopify can be attractive because you can run one storefront. But wholesale parts businesses often end up adding apps or custom work for things like negotiated pricing, quoting, and account workflows. www.bigcommerce.comoroinc.com

3. OroCommerce — only if your pricing is complicated

Consider it if you have:

• hundreds of wholesale accounts
• multiple price tiers
• regional pricing
• sales reps creating orders
• ERP-driven pricing rules

It is built specifically for B2B workflows, but it is probably excessive for a small supplier with a few buyers. oroinc.com

A practical rule of thumb

• 5–50 wholesale customers, simple negotiated pricing: BigCommerce or Shopify + B2B tools
• 50–500 customers, many price lists: BigCommerce B2B Edition
• Thousands of accounts / complex distributor workflows: OroCommerce or Adobe Commerce

A few details would change the recommendation:

1. Roughly how many SKUs/parts do you sell?
2. Do customers each have their own negotiated price lists, or are they in tiers (dealer / distributor / reseller)?
3. What system holds your inventory today (QuickBooks, NetSuite, ERP, spreadsheet, etc.)?

For a small B2B parts supplier with a handful of wholesale accounts, I’d put BigCommerce first, especially if customer-specific pricing is the main requirement.

My ranking

1. BigCommerce — probably your sweet spot

BigCommerce has a particularly good model for wholesale: Customer Groups + Price Lists. Price Lists can specify prices down to the SKU/variant level and be assigned to customer groups; BigCommerce also supports assigning individualized pricing to companies. docs.bigcommerce.com

So you could have:

• Customer A → $12.40 for part X
• Customer B → $11.75 for part X
• Customer C → $13.10 for part X
• Everyone else → $15.99 retail

without creating duplicate products or relying on coupon codes.

It also supports bulk pricing and customer-specific catalogs, which are useful for parts distribution. www.bigcommerce.com

That's the model I'd want for your business.

BigCommerce

2. Adobe Commerce — most powerful, but probably overkill

Adobe Commerce's B2B functionality has Shared Catalogs, where you can create a catalog with custom prices and assign it to particular companies. You can set either fixed prices or percentage discounts and add quantity/tier pricing. experienceleague.adobe.com

It's extremely capable if you eventually have:

• hundreds/thousands of wholesale accounts
• complicated contract pricing
• multiple websites
• elaborate customer hierarchies
• ERP/PIM integrations
• sophisticated purchasing workflows

But for "we have a few wholesale customers and each gets their own price sheet," I'd consider it unnecessarily heavy.

Adobe Commerce

3. Shopify Plus — good, but I'd choose it for other reasons

Shopify's B2B catalogs can have fixed prices, percentage adjustments, product restrictions and volume pricing. On Shopify Plus, you get unlimited catalogs and can assign them directly to companies/company locations. help.shopify.com

The catch is that I'd pick Shopify Plus because you specifically want the Shopify ecosystem, storefront experience, apps, etc., rather than because it has the best customer-specific pricing model.

For a small parts distributor, Plus can also be a lot of platform for the size of the operation.

Shopify

What I'd actually do in your situation

If your pricing looks something like:

Retail price → customer-specific price → quantity break

I'd choose BigCommerce and structure it roughly as:

Product catalog
→ master SKU/product data

Customer accounts
→ one account/company per wholesale customer

Price lists
→ one negotiated price list per customer, or shared lists for customers with identical pricing

Customer groups
→ organize accounts that share pricing/catalog rules

Bulk pricing
→ additional quantity breaks where applicable

That gives you a clean path from 5 wholesale customers today to dozens or hundreds later without rebuilding the store.

One important question, though: how your pricing is actually maintained matters more than the storefront. If you currently have Excel/CSV price sheets like Customer A / SKU / agreed price, I can compare BigCommerce vs Shopify vs WooCommerce specifically for importing and maintaining those customer price lists, which is where the differences become much more significant.
