For an enterprise retailer adding a dropshipping channel, the platform choice usually depends on whether you are building a supplier/vendor marketplace or simply adding vendor-fulfilled SKUs to your existing catalog. The hardest requirements are typically:

• Complex B2B pricing (customer-specific price lists, contracts, tiers, rebates)
• Account hierarchies (parent companies, buyers, approvers)
• Vendor portals (vendors manage products, inventory, SLAs, fulfillment)
• Multi-vendor order routing and split shipments
• Vendor commissions/settlements
• ERP/WMS integration
• Rules around inventory ownership, returns, and customer service

A shortlist I would evaluate:

TechTarget Elogic Commerce## How I would think about the architecture

Option 1: “Dropship channel” (vendors fulfill, you remain merchant of record)

Typical stack:

• Commerce platform: Adobe Commerce / Salesforce Commerce Cloud / Shopify Plus
• Marketplace or vendor management layer: Mirakl or custom vendor services
• ERP/WMS: SAP, Oracle, NetSuite, Manhattan, etc.
• Integration layer: order routing, inventory sync, vendor SLAs

This works well if vendors are an extension of your assortment rather than independent sellers.

Option 2: “Marketplace” (vendors operate like sellers)

Look for:

• Vendor onboarding workflows
• Vendor dashboards
• Product approval queues
• Vendor-managed catalog
• Vendor inventory feeds
• Automated commissions
• Seller payouts
• Dispute/return workflows

A marketplace platform such as Mirakl is commonly paired with an enterprise commerce platform for this model. SPXCommerce

Platform notes

Adobe Commerce

Strong candidate when you have very complicated merchandising and B2B rules:

• Shared catalogs
• Customer-specific pricing
• Negotiated quotes
• Purchase approvals
• Complex checkout logic

It is often chosen when the business rules are more important than speed of implementation. Elogic Commerce

Salesforce Commerce Cloud

Good fit if:

• Your sales teams operate heavily in Salesforce
• Customer account data and commerce need to be unified
• You have enterprise CRM workflows

Salesforce highlights B2B capabilities such as contract pricing, custom catalogs, and multi-user account hierarchies. Salesforce

Shopify Plus

Good fit if:

• You want faster implementation
• You have strong DTC operations
• B2B complexity is moderate

Shopify supports B2B catalogs, company accounts, purchasing controls, and integrations through APIs, but highly customized vendor marketplace workflows often require additional systems. Shopify Help Center

Composable commerce (commercetools)

Worth considering if you are a large retailer with:

• Multiple brands
• Multiple regions
• Complex fulfillment orchestration
• A strong engineering organization

You get flexibility, but you build more of the business logic yourself. TechTarget

My evaluation checklist for your use case

Before selecting, I would score vendors against:

1. Vendor portal

• Can suppliers upload/manage products?
• Can they view orders and shipment obligations?
• Can they manage inventory feeds?
• Order orchestration

• Can one customer order split across five vendors?
• Can you show one checkout experience?
• Can returns route correctly?
• B2B pricing

• Contract pricing?
• Customer-specific catalogs?
• Volume discounts?
• Rebates?
• Operations

• Vendor SLA tracking?
• Dropship shipping labels?
• Late shipment monitoring?
• Vendor performance reporting?
• Enterprise integration

• ERP synchronization
• Tax engine
• OMS
• Customer service platform

For a large retailer with serious B2B rules plus a vendor ecosystem, I would typically start evaluations with Adobe Commerce + marketplace capability, Salesforce Commerce Cloud + marketplace capability, and composable commerce + a marketplace platform. If the vendor portal is the centerpiece rather than just fulfillment support, I would put more weight on a marketplace layer like Mirakl than on the storefront alone. Elogic Commerce SPXCommerce

If you share your approximate scale (SKUs, vendors, order volume, ERP, and whether vendors set prices or only fulfill), I can narrow this to a more realistic shortlist.

For an enterprise retailer adding dropshipping while retaining complex B2B commerce, I’d put OroCommerce at the top of the shortlist, with Adobe Commerce and BigCommerce B2B Edition as the other two worth serious evaluation.

1. OroCommerce — strongest fit for your particular model

Oro is unusually aligned with the combination you're describing: enterprise B2B + multiple vendors + dropshipping + vendor self-service.

Its marketplace offering explicitly supports vendor onboarding, seller accounts, vendor employees/permissions, inventory, product management, order management, multi-warehouse fulfillment and full or partial dropshipping. It also provides buyer and seller self-service portals. ORO INC. Oro Documentation

On the B2B side, Oro supports:

• Parent/child corporate account structures
• Granular roles and permissions
• Customer-specific catalogs and pricing
• Complex pricing rules
• RFQ/negotiation
• Approval and order-routing workflows
• Multiple organizations/sites
• ERP/PIM/CRM/WMS/3PL integrations
• Multi-vendor and marketplace models ORO INC. ORO INC.

The particularly relevant piece is its visual workflow engine, which can automate approvals, order routing and exception handling rather than forcing all of those rules into custom application code. ORO INC. ORO INC.

For your architecture, I'd investigate Oro first if "vendor portal" means vendors actually need to log in and manage products, inventory, fulfillment and orders themselves.

2. Adobe Commerce — strongest if you're already in the Adobe ecosystem

Adobe Commerce B2B is very mature for the buyer/customer side of complex B2B.

It supports company hierarchies, roles, permissions, shared catalogs, company-specific pricing, quotes, credit and purchase-order approval rules. Its approval engine can, for example, route POs based on order value, shipping cost, SKU count and organizational roles. Experience League Experience League Experience League

That makes it a strong choice if your complexity looks like:

"Different corporate customers get different catalogs/prices/terms, with elaborate purchasing permissions and approval chains."

The caveat is the vendor portal. Adobe's native B2B capabilities are primarily about your customers and their organizations, rather than turning third-party suppliers into first-class sellers. You'd generally need a marketplace/vendor extension or custom implementation for that layer.

So Adobe can absolutely support your model, but the architecture is more likely to become:

Adobe Commerce + B2B + marketplace/vendor extension + ERP/PIM/OMS

rather than Oro's more integrated marketplace approach.

3. BigCommerce B2B Edition — attractive if you prioritize SaaS simplicity

BigCommerce has strong B2B capabilities including company hierarchies, roles, buyer permissions, customer-specific pricing/catalogs, quotes, invoices, purchase-order workflows and a buyer portal. Its APIs also expose company, pricing, quote and buyer-portal functionality for headless implementations. BigCommerce BigCommerce BigCommerce

Its B2B buyer portal is particularly well developed: company users can manage orders, quotes and invoices, with roles controlling what they can do. BigCommerce BigCommerce

But again, buyer portal ≠ vendor portal. If your dropship suppliers need substantial operational functionality, you'll likely be adding marketplace/vendor software or building that layer yourself.

How I'd frame the decision

If your requirement is essentially:

"We're a retailer. We have complicated B2B customers, and we're adding hundreds/thousands of third-party suppliers whose products we want to dropship."

I'd evaluate them in this order by architectural fit, rather than treating them as generic ecommerce platforms:

1. OroCommerce + OroMarketplace — investigate first for a genuinely multi-vendor B2B model.
2. Adobe Commerce — particularly compelling if you already have Adobe Commerce and substantial Adobe/ERP investment.
3. BigCommerce B2B Edition — compelling when SaaS/headless simplicity is more important and the vendor layer can live in adjacent systems.

The key diligence question isn't just "Does it support B2B?" All three can. It's where the vendor/order orchestration boundary lives.

For your use case I'd specifically test a single order containing:

B2B customer → negotiated customer price → multiple vendors → dropship inventory → vendor-specific fulfillment SLA → split shipment → vendor PO → customer invoice → returns → commission/margin reconciliation

and see which platform handles that flow natively versus requiring custom OMS/integration work. That's likely to expose the real difference much faster than a standard feature checklist.

The caveat is the vendor portal. Adobe's native B2B capabilities are primarily about your customers and their organizations, rather than turning third-party suppliers into first-class sellers. You'd generally need a marketplace/vendor extension or custom implementation for that layer.

So Adobe can absolutely support your model, but the architecture is more likely to become:

Adobe Commerce + B2B + marketplace/vendor extension + ERP/PIM/OMS

rather than Oro's more integrated marketplace approach.

3. BigCommerce B2B Edition — attractive if you prioritize SaaS simplicity

BigCommerce has strong B2B capabilities including company hierarchies, roles, buyer permissions, customer-specific pricing/catalogs, quotes, invoices, purchase-order workflows and a buyer portal. Its APIs also expose company, pricing, quote and buyer-portal functionality for headless implementations. docs.bigcommerce.com docs.bigcommerce.com docs.bigcommerce.com

Its B2B buyer portal is particularly well developed: company users can manage orders, quotes and invoices, with roles controlling what they can do. docs.bigcommerce.com docs.bigcommerce.com

But again, buyer portal ≠ vendor portal. If your dropship suppliers need substantial operational functionality, you'll likely be adding marketplace/vendor software or building that layer yourself.

How I'd frame the decision

If your requirement is essentially:

"We're a retailer. We have complicated B2B customers, and we're adding hundreds/thousands of third-party suppliers whose products we want to dropship."

For an enterprise retailer adding dropshipping, the platform decision usually comes down to whether you need a B2B commerce engine, a multi-vendor marketplace/vendor network, or a dropship order orchestration layer. Many commerce platforms are strong at one or two of these, but not all three.

Here are the leading options:

My shortlist for your use case

1. If dropshipping is a strategic channel (hundreds/thousands of vendors)

Look hardest at:

• Kibo Commerce
• commercetools
• Adobe Commerce + marketplace/vendor extensions

Key capabilities to validate:

• Vendor self-service onboarding
• Vendor SKU/catalog management
• Inventory feeds (API, EDI, CSV)
• Vendor-specific SLAs
• Split orders by supplier
• Automated purchase orders
• Returns routing
• Vendor scorecards
• Commission/payment reconciliation

Vendor portals typically need suppliers to manage products, inventory, orders, and fulfillment without retailer intervention. Elogic Commerce

2. If you are primarily a retailer adding a supplier-fulfilled assortment

Consider:

• Adobe Commerce
• Salesforce Commerce Cloud
• Microsoft Dynamics 365 Commerce

You likely care more about:

• complex promotions
• customer segmentation
• loyalty
• omnichannel inventory
• ERP integration
• tax rules
• B2B accounts

3. If your B2B rules are unusually complex

Examples:

• negotiated contracts
• customer-specific assortments
• regional pricing
• buying groups
• approval chains
• purchase orders
• net payment terms
• punchout procurement

Prioritize:

1. Dynamics 365 Commerce
2. Adobe Commerce
3. Salesforce Commerce Cloud
4. commercetools

Salesforce, for example, supports buyer groups and entitlement rules to control product visibility and pricing by account segment. Salesforce

Architecture I would expect for an enterprise retailer

A common enterprise pattern is:

Commerce platform
→ storefront, B2B accounts, pricing, checkout

Marketplace/vendor portal layer
→ supplier onboarding, catalogs, vendor users

OMS (order management system)
→ routing logic: warehouse vs dropship vendor

ERP
→ finance, procurement, inventory ownership

Integration layer
→ APIs/EDI/vendor feeds

I would avoid choosing a storefront platform alone and expecting it to become a full dropship marketplace.

Questions that would narrow the recommendation

1. How many vendors do you expect in year 1 and year 3 (10, 100, 10,000)?
2. Are vendors only fulfilling orders, or do they also set prices and manage listings?
3. Do you need B2B buyer portals (wholesale customers), or mainly supplier portals?
4. What ERP/OMS are you running (SAP, Oracle, Dynamics, NetSuite, Manhattan, Blue Yonder, etc.)?
5. Are you replacing your commerce platform or adding a channel beside an existing one?

Commerce platform
→ storefront, B2B accounts, pricing, checkout

Marketplace/vendor portal layer
→ supplier onboarding, catalogs, vendor users

OMS (order management system)
→ routing logic: warehouse vs dropship vendor

ERP
→ finance, procurement, inventory ownership

Integration layer
→ APIs/EDI/vendor feeds

I would avoid choosing a storefront platform alone and expecting it to become a full dropship marketplace.

Questions that would narrow the recommendation

For an enterprise retailer adding dropshipping while retaining complex B2B rules, I’d put Spryker and Adobe Commerce at the top of the shortlist—but for slightly different reasons.

1. Spryker — my first choice

Spryker is particularly well aligned with your combination of requirements.

Its marketplace capability is built into the commerce platform rather than being an afterthought. Third-party merchants get a Merchant Portal where they can manage products, offers, pricing, inventory, orders and fulfillment. The platform also supports splitting a customer's order by merchant—very relevant to dropshipping. Spryker Documentation Spryker Documentation

It also explicitly supports B2B marketplaces, and Spryker positions the platform around complex business models and composable enterprise commerce. Spryker Documentation Spryker

Why I'd favor it for you: you can model:

Retailer → B2B customer → contract/pricing rules → products → multiple dropship vendors → vendor-specific fulfillment

without forcing the vendor experience and your customer-facing B2B experience into the same administrative model.

2. Adobe Commerce — strongest B2B-native alternative

Adobe Commerce has exceptionally mature B2B capabilities: company hierarchies, buyer roles/permissions, shared catalogs, customer-specific pricing, negotiated quotes, purchase-order approval rules, payment-on-account and requisition lists. Experience League Adobe Developer

That's compelling if your biggest challenge is complex B2B commercial logic.

The weakness is that vendor/dropship management isn't as native as Spryker's marketplace model. You'd generally introduce marketplace/vendor functionality through extensions and/or custom architecture rather than getting the same first-class merchant-portal model. Adobe's B2B capabilities are primarily designed around your retailer selling to business customers. Experience League

How I'd decide

Choose Spryker if:

• Dropshipping/vendor onboarding is strategically important.
• Vendors need their own portal.
• Vendors manage inventory, offers, pricing and fulfillment.
• You expect many vendors.
• You need different commercial models per vendor.
• You want marketplace functionality without building the entire vendor layer yourself.

Choose Adobe Commerce if:

• Your primary complexity is B2B customer contracts, catalogs, pricing and approvals.
• Vendors are relatively simple suppliers behind your storefront.
• You already have significant Adobe/Magento investment.
• Your organization has strong Adobe Commerce engineering capability.

One architectural point I'd emphasize

Don't treat this as simply "B2B commerce + dropship integration." At enterprise scale, you really have three rule systems:

1. Buyer rules — account hierarchy, contracts, pricing, approval limits, payment terms.
2. Assortment/vendor rules — which vendors can sell which SKUs to which customers at what price.
3. Fulfillment rules — inventory source, vendor SLA, routing, split shipments, returns, cancellations and settlement.

The platform should let you keep those concerns separate while coordinating them at checkout.

If you're starting from a clean slate, I'd shortlist Spryker first, Adobe Commerce second, and VTEX third. The deciding exercise would be a proof-of-concept around one realistic order: B2B customer-specific price + vendor-specific assortment + vendor inventory + split fulfillment + PO approval + vendor settlement. That will expose platform limitations much faster than a generic feature checklist.

Adobe Commerce has exceptionally mature B2B capabilities: company hierarchies, buyer roles/permissions, shared catalogs, customer-specific pricing, negotiated quotes, purchase-order approval rules, payment-on-account and requisition lists. experienceleague.adobe.com developer.adobe.com

That's compelling if your biggest challenge is complex B2B commercial logic.

For an enterprise retailer adding dropship while retaining complex B2B rules, I’d shortlist Mirakl + Adobe Commerce first, rather than looking for a single platform to do everything.

My ranking

1. Mirakl + Adobe Commerce — best fit for your scenario

• Mirakl is purpose-built for enterprise marketplace/dropship operations, including vendor onboarding, self-service vendor portals, catalog ingestion, vendor connectivity via API/CSV/XML/EDI, and dropship workflows. Mirakl Mirakl
• Adobe Commerce handles the sophisticated B2B buyer side: company hierarchies, roles/permissions, approval rules, shared catalogs, customer-specific pricing, quotes, payment/shipping rules and requisition lists. Experience League Adobe Developer
• The two have integration options, so you can keep the commerce experience and B2B rules in Adobe while making Mirakl the vendor/dropship operating layer. Mirakl specifically lists Adobe Commerce among its supported integrations. Mirakl
• SAP Commerce Cloud + Mirakl — strongest if you're already heavily invested in SAP

• I'd favor this when your enterprise architecture revolves around SAP ERP/S4, complex pricing, customer contracts, and deep back-office integration.
• Mirakl can provide the vendor/dropship layer rather than forcing SAP Commerce to become a marketplace/vendor-management system.
• Adobe Commerce alone — strongest if B2B complexity dominates and dropship is relatively straightforward

• Adobe's native B2B functionality is unusually deep: company organizational structures, purchasing permissions, approval rules, negotiated quotes, shared catalogs, custom pricing, payment terms and requisition lists. Experience League Adobe Developer
• But I'd be cautious about using Adobe itself as the vendor/dropship operating platform. Mirakl is much more purpose-built around vendor onboarding, vendor portals, catalog ingestion, fulfillment and multi-vendor operations. Mirakl

The architecture I'd recommend

Customer / B2B experience
→ Adobe Commerce

B2B rules
→ company hierarchy + customer-specific catalogs/prices + approval rules + quotes + payment terms
→ Adobe Commerce

Vendor onboarding & portal
→ catalog feeds + EDI/API + vendor validation + vendor self-service
→ Mirakl

Dropship orchestration
→ inventory/availability + vendor fulfillment + shipment/order status + vendor performance
→ Mirakl

ERP / finance / enterprise order management
→ SAP / Oracle / existing OMS

That separation is important. Don't make your commerce platform carry all the vendor-management complexity just because it can technically support a dropship catalog.

Mirakl explicitly supports running marketplace and dropship together, with the same vendor relationships, catalog and operational tooling, and lets a vendor operate as marketplace, dropship, or both. Mirakl

When I'd choose something else

If your requirement is primarily "complex B2B commerce" and dropship is just another fulfillment source, I'd lean Adobe Commerce.

If the requirement is "we're becoming a multi-vendor retailer with hundreds/thousands of suppliers, vendor self-service, feeds, onboarding, commissions/margins and dropship", I'd lean Mirakl + your existing/selected commerce platform.

If you tell me roughly (a) number of vendors, (b) number of B2B customers, (c) SAP/Oracle/other ERP, (d) whether you need marketplace as well as dropship, and (e) whether customers have contract-specific pricing/approval workflows, I can give you a tighter Adobe vs SAP Commerce vs commercetools vs Mirakl architecture recommendation.

For an enterprise retailer adding a dropshipping channel, I would look beyond a standard ecommerce platform. Your requirements sound closer to a B2B commerce + marketplace/vendor ecosystem + order orchestration problem.

The strongest candidates are:

For your specific use case, I would shortlist:

1. Adobe Commerce + marketplace/vendor portal layer

Best if you need:

• Vendor onboarding workflows
• Vendor-specific catalogs
• Complex assortment rules
• Multiple price books
• Regional/channel rules
• Custom checkout logic
• Deep ERP/PIM/OMS integration

Typical architecture:

• Commerce engine: Adobe Commerce
• Marketplace/vendor module or custom portal
• OMS for routing
• ERP/PIM for product and inventory governance

2. Salesforce Commerce Cloud + Salesforce ecosystem

Best if vendors are part of a broader partner ecosystem and you need:

• Vendor relationship management
• Sales workflows
• Account-based commerce
• Customer service integration

3. Microsoft Dynamics 365 Commerce

Best if your dropship program depends heavily on:

• ERP-controlled inventory
• Vendor purchasing
• Financial reconciliation
• Complex fulfillment rules

Vendor portal capabilities I would require

For an enterprise dropship channel, make sure the platform supports:

• Vendor onboarding

• Approval workflows
• Contracts/compliance documents
• Vendor profiles
• Vendor catalog management

• SKU submission
• Product attributes
• Images/content
• Approval workflows
• Commercial rules

• Vendor-specific pricing
• Commission/margin rules
• MAP pricing
• Customer segment pricing
• Promotions
• Order orchestration

• Split orders by vendor
• Route based on inventory/location/cost
• Vendor acknowledgements
• Shipment tracking feeds
• B2B buyer rules

• Customer-specific catalogs
• Contract pricing
• Buying groups
• Approval chains
• PO workflows
• Net terms
• Enterprise integrations

• ERP
• OMS
• PIM
• EDI/API vendor feeds
• Tax and compliance systems

My practical recommendation

For a large retailer, I would usually evaluate:

1. Adobe Commerce + OMS + vendor portal if you want maximum control.
2. Dynamics 365 Commerce if your ERP is the operational backbone.
3. Salesforce Commerce Cloud if CRM/customer relationships drive the business.
4. Shopify Plus only if you want faster deployment and your vendor marketplace requirements are moderate.

The key architecture decision is whether you are building a dropship channel (your vendors fulfill your orders) or a true marketplace (vendors own products, pricing, seller accounts, and customer relationships). The latter pushes you toward marketplace-capable platforms rather than traditional commerce platforms.

If you’re an enterprise retailer adding dropshipping to an existing B2C/B2B operation, I’d shortlist Spryker, Adobe Commerce, and commercetools—with Spryker as my first look if the vendor/marketplace side is central.

My recommendation: Spryker

Spryker is unusually well aligned with your combination of requirements. Its enterprise marketplace offering is explicitly designed for multiple business models and includes a B2B self-service portal alongside marketplace capabilities. Spryker

That matters because your dropship operation isn't merely "B2B ecommerce." You potentially need:

• Vendor onboarding and vendor-specific permissions
• Vendor product/catalog management
• Vendor-specific cost and selling-price rules
• Inventory/availability feeds
• Order routing to the correct supplier
• Supplier fulfillment and shipment-status updates
• Commission/margin rules
• Customer-specific pricing and contracts
• Approval workflows and purchasing hierarchies
• Different rules by vendor, brand, customer, region, channel, and SKU
• Your retailer remaining the merchant/customer-facing party, while vendors fulfill behind the scenes

Spryker is particularly compelling when those requirements need to coexist rather than being bolted onto a conventional storefront.

Adobe Commerce is my second choice

If your biggest challenge is extremely sophisticated B2B pricing, catalogs, accounts and purchasing rules, Adobe Commerce is excellent.

Its B2B capabilities include company hierarchies, company-specific catalogs, custom pricing, quotes, purchasing permissions, quick orders and requisition lists. Experience League Experience League

For example, Adobe's shared catalogs let you create gated catalogs with different product selections and pricing for particular companies. Experience League Experience League

The caveat is that vendor marketplace functionality isn't its core strength. You'd generally be looking at marketplace/vendor extensions plus customization and integration. For a retailer where dropship vendors are becoming a major part of the business model, I'd therefore favor Spryker.

commercetools if your architecture team wants composable

I'd put commercetools high on the list if you're already pursuing a headless/composable architecture and have a strong engineering organization.

It provides API-first commerce primitives and supports B2B concepts such as custom catalogs, pricing, account hierarchies and customer-specific promotions. Shopify

The tradeoff is that you'll be assembling more of the vendor-management/marketplace operating model yourself. That's potentially a feature—not a bug—if your enterprise wants maximum architectural control.

Shopify Plus would not be my first choice here

Shopify Plus is attractive if speed and operational simplicity dominate. Shopify has substantially expanded its B2B capabilities, including quantity rules, volume pricing, quick ordering and B2B-specific storefront customization. Shopify Help Center Shopify Help Center

But for your stated requirement—complex B2B rules + vendor portals + dropshipping—I'd be wary of creating an architecture that's heavily dependent on apps and custom integrations. Shopify can do it, but it isn't the platform I'd choose if the vendor network itself is becoming strategically important.

How I'd make the decision

I'd score the platforms against your actual operating model rather than generic "B2B features":

1. Vendor onboarding & portal — Can suppliers manage SKUs, content, inventory, orders, returns and shipping themselves?
2. Rule engine — Can you express customer × vendor × SKU × geography × channel pricing/availability rules?
3. Order orchestration — Can one customer order be split across multiple vendors without creating a bad customer experience?
4. Inventory — Real-time/near-real-time vendor inventory and safety-stock rules.
5. Margin control — Vendor cost + retailer markup + customer contract price + promotions.
6. B2B account hierarchy — Parent company → divisions → locations → buyers → approval limits.
7. ERP/OMS/PIM integration — Especially important if your existing retail stack remains authoritative.
8. Returns/cancellations — Vendor-specific policies while maintaining a unified customer experience.
9. Scale of vendor network — 20 vendors is very different from 2,000.
10. Who owns the customer relationship? — This substantially affects the architecture.

Bottom line: If you're building a serious enterprise retail + B2B + dropship marketplace, I'd start the RFP with Spryker, Adobe Commerce, and commercetools, in that order. If the requirement is primarily sophisticated B2B rather than a true multi-vendor marketplace, I'd move Adobe Commerce to #1.

If you tell me your approximate GMV, number of vendors, ERP/OMS (SAP, Oracle, Dynamics, etc.), number of SKUs, and whether vendors need a self-service portal, I can turn this into a concrete platform architecture and RFP scorecard.

The caveat is that vendor marketplace functionality isn't its core strength. You'd generally be looking at marketplace/vendor extensions plus customization and integration. For a retailer where dropship vendors are becoming a major part of the business model, I'd therefore favor Spryker.

commercetools if your architecture team wants composable

I'd put commercetools high on the list if you're already pursuing a headless/composable architecture and have a strong engineering organization.

It provides API-first commerce primitives and supports B2B concepts such as custom catalogs, pricing, account hierarchies and customer-specific promotions. Shopify

The tradeoff is that you'll be assembling more of the vendor-management/marketplace operating model yourself. That's potentially a feature—not a bug—if your enterprise wants maximum architectural control.

Shopify Plus would not be my first choice here

Shopify Plus is attractive if speed and operational simplicity dominate. Shopify has substantially expanded its B2B capabilities, including quantity rules, volume pricing, quick ordering and B2B-specific storefront customization. help.shopify.com help.shopify.com

But for your stated requirement—complex B2B rules + vendor portals + dropshipping—I'd be wary of creating an architecture that's heavily dependent on apps and custom integrations. Shopify can do it, but it isn't the platform I'd choose if the vendor network itself is becoming strategically important.

How I'd make the decision

I'd score the platforms against your actual operating model rather than generic "B2B features":

For an enterprise retailer adding dropshipping, I’d shortlist Adobe Commerce, BigCommerce, and a composable/marketplace layer such as commercetools + Mirakl. The key distinction is whether “vendor portal” means a true seller operating environment or simply supplier integration.

My ranking

Adobe Commerce is probably the strongest single-platform candidate if your B2B rules are the harder problem. Its B2B capabilities include company hierarchies, roles/permissions, company-specific catalogs and pricing, negotiated quotes, purchase orders, payment/shipping restrictions, and requisition lists. Experience League Experience League

BigCommerce is particularly interesting if you want a cleaner enterprise implementation. Its B2B Edition has company accounts, buyer roles, approval workflows, quotes, invoices, payment controls and a Buyer Portal. Companies can be mapped to customer groups and differentiated pricing. BigCommerce BigCommerce

The catch: neither Adobe Commerce nor BigCommerce is, by itself, an especially sophisticated supplier marketplace portal. If your dropship suppliers need to log in, manage their own SKUs/content, receive orders, acknowledge/fulfill them, manage inventory, handle SLAs/returns, and potentially compete on offers, I'd architect the supplier side separately.

What I'd consider for your use case

If your requirements look like:

Retailer → B2B customer → complex contract pricing/eligibility → product supplied by vendor → vendor receives order → vendor fulfills → retailer owns customer experience

I'd favor:

Adobe Commerce + dedicated vendor/dropship integration layer

or, for a more future-proof architecture:

commercetools + Mirakl (marketplace/vendor management) + OMS/ERP

The second approach gives you much more freedom to model product offers, vendor-specific inventory, fulfillment rules, commissions, vendor SLAs and seller onboarding, while keeping the commerce engine focused on customer/catalog/pricing logic.

One important distinction I'd make before choosing: Are your “vendors” essentially dropship suppliers that fulfill your retailer-owned assortment, or do you want a true marketplace where vendors own the products/offers and control portions of the catalog? That answer could change my recommendation substantially.

For an enterprise retailer adding dropshipping while retaining sophisticated B2B rules, I’d shortlist Adobe Commerce, SAP Commerce Cloud, and Shopify Plus—but they fit different operating models.

My ranking

*Vendor portals and marketplace capabilities generally require extensions, custom development, or a separate marketplace/supplier application rather than being equivalent to native B2B functionality.

1. Adobe Commerce — my default recommendation

If your retailer already has complicated customer-specific pricing, account hierarchies, approval rules, credit limits, quotes, and fulfillment logic, Adobe Commerce is probably the strongest fit.

Its B2B model supports company hierarchies, roles/permissions, shared catalogs, custom pricing, negotiable quotes, purchase-order approval rules, requisition lists, company credit, and company-specific payment/shipping methods. Experience League Experience League Experience League

That's particularly useful for dropshipping because you can model the buyer side independently from the supplier/fulfillment side, then integrate supplier inventory, cost, routing, PO creation, shipment confirmation, and settlement through APIs/custom services.

experienceleague.adobe.com

Downside: you'll likely need significant implementation work for a polished multi-vendor portal. If "vendor portal" means suppliers log in, manage SKUs, inventory, orders, ASN/tracking, invoices, returns, etc., I would architect that as a dedicated supplier experience rather than assume the core B2B module provides it.

2. SAP Commerce Cloud — strongest for very complex enterprise ecosystems

I'd put SAP Commerce Cloud ahead of Adobe if you're already heavily invested in SAP—particularly SAP S/4HANA, SAP ERP, or SAP's broader supply-chain stack.

It's compelling when dropshipping isn't merely "another fulfillment option," but involves complicated supplier relationships, procurement, inventory availability, contracts, pricing, tax, fulfillment orchestration and ERP integration.

Shopify's current 2026 enterprise-platform comparison itself characterizes SAP Commerce as particularly suited to complex B2B scenarios. Shopify

The tradeoff is implementation complexity and cost.

3. Shopify Plus — best if speed and operational simplicity matter

Shopify Plus has become considerably more capable for B2B. It supports companies and company locations, location-specific pricing/catalogs, payment terms, quantity rules, volume pricing, and—on Plus—unlimited B2B catalogs and direct catalog assignment to individual companies/locations. Shopify Help Center Shopify Help Center

It can also support approval-style workflows by submitting B2B orders as drafts for review, and Plus adds deposits and partial payments. Shopify Help Center Shopify Help Center

I'd choose it when:

• Your B2B rules are complex but not exceptionally bespoke.
• You want to launch the dropship channel relatively quickly.
• Your merchandising/ecommerce team values SaaS simplicity.
• You're comfortable building the supplier portal and orchestration layer outside Shopify.

I wouldn't make Shopify Plus my first choice if your differentiator is extremely intricate customer-specific pricing, multi-level purchasing authority, sophisticated contract logic, or highly customized order/fulfillment orchestration.

help.shopify.com

4. commercetools — interesting if you're building a composable architecture

If you're an enterprise retailer that already thinks in terms of headless commerce + ERP/PIM/OMS + specialized services, commercetools is worth serious consideration.

For your use case, I'd potentially make the architecture:

Commerce engine → B2B rules → supplier/marketplace service → OMS → ERP → suppliers

rather than forcing all of those responsibilities into the commerce platform.

That's powerful, but it means you are buying an architecture, not a turnkey dropshipping platform.

The important distinction: "vendor portal"

I'd clarify this before selecting a platform.

If by vendor portal you mean:

"Suppliers need to log in, maintain products, submit inventory, receive orders, acknowledge POs, provide tracking, manage returns, and see settlement."

Then I would not select a commerce platform solely based on whether it has a vendor portal.

Instead, I'd evaluate the platform on these five capabilities:

1. B2B customer model — account hierarchies, roles, permissions, contracts.
2. Pricing/rules engine — customer × SKU × quantity × geography × contract × promotion.
3. Order orchestration — split orders by supplier, inventory source, ship-from location, etc.
4. Supplier integration — APIs/EDI, inventory feeds, PO/ASN/order-status workflows.
5. Marketplace/supplier UX — supplier onboarding, catalog management, compliance, commissions/settlement.

For an enterprise retailer, I'd generally keep supplier management and fulfillment orchestration decoupled from the storefront. That prevents your commerce platform from becoming the system of record for supplier operations.

Bottom line

If you gave me only your description and asked me to pick three to run an RFP:

1. Adobe Commerce — best overall balance for a highly customized enterprise retailer.
2. SAP Commerce Cloud — strongest if you're SAP-centric and the operational model is very complex.
3. Shopify Plus — strongest if speed, SaaS simplicity, and lower implementation burden outweigh maximum rule flexibility.

If you tell me your ERP/OMS (SAP, Oracle, Microsoft, custom), approximate SKU/vendor count, and whether vendors need a true self-service portal, I can narrow this to a concrete architecture and RFP scorecard.

The important distinction: "vendor portal"

I'd clarify this before selecting a platform.

If by vendor portal you mean:

"Suppliers need to log in, maintain products, submit inventory, receive orders, acknowledge POs, provide tracking, manage returns, and see settlement."

Then I would not select a commerce platform solely based on whether it has a vendor portal.

Instead, I'd evaluate the platform on these five capabilities:

1. B2B customer model — account hierarchies, roles, permissions, contracts.
2. Pricing/rules engine — customer × SKU × quantity × geography × contract × promotion.
3. Order orchestration — split orders by supplier, inventory source, ship-from location, etc.
4. Supplier integration — APIs/EDI, inventory feeds, PO/ASN/order-status workflows.
5. Marketplace/supplier UX — supplier onboarding, catalog management, compliance, commissions/settlement.

For an enterprise retailer, I'd generally keep supplier management and fulfillment orchestration decoupled from the storefront. That prevents your commerce platform from becoming the system of record for supplier operations.

If you tell me your ERP/OMS (SAP, Oracle, Microsoft, custom), approximate SKU/vendor count, and whether vendors need a true self-service portal, I can narrow this to a concrete architecture and RFP scorecard.

For an enterprise retailer adding dropshipping, I’d put Spryker at the top of the shortlist if the vendor portal is a first-class requirement.

My shortlist

Why I'd favor Spryker

Spryker is unusually well aligned with your combination of requirements. Its Marketplace functionality has a Merchant Portal where vendors can manage products/offers, pricing and stock, fulfill orders, and manage their profiles. Spryker Documentation Spryker Documentation

More importantly, Spryker has explicit B2B Marketplace capabilities, including merchant-specific pricing and product approval workflows. Spryker Documentation Its current documentation also includes Merchant B2B Contracts, which is particularly relevant if your dropship vendors will have contractual commercial terms. Spryker Documentation

That gives you a fairly natural model:

Your retailer → B2B customer → product/catalog rules → order → vendor allocation → vendor portal → fulfillment → customer

Adobe Commerce is my second choice

Adobe Commerce is extremely strong if your hardest problem is complex customer-specific B2B commerce, rather than the vendor ecosystem itself.

It natively supports company hierarchies, roles/permissions, shared catalogs, customer-specific pricing, negotiable quotes, purchase-order approval rules, requisition lists, and company-specific payment/shipping methods. Experience League Adobe Developer

The catch is that vendor/dropship management isn't as native a centerpiece as it is in Spryker Marketplace. You'd likely be building or integrating the supplier portal/marketplace layer.

commercetools is the architectural alternative

commercetools is compelling if you're already committed to a composable/headless architecture.

Its B2B model supports company/division hierarchies, buyer roles, inherited permissions, customer-specific stores/assortments/prices, and approval rules. commercetools Documentation commercetools Documentation

But, like Adobe, you'd generally assemble the vendor portal and marketplace operating model rather than getting Spryker's merchant experience as the core product.

My recommendation

If I were running your platform selection:

1. Spryker — strongest overall match for enterprise retailer + B2B complexity + dropship vendors + vendor portal.
2. Adobe Commerce — strongest if B2B customer rules/catalog/pricing are substantially more important than vendor self-service.
3. commercetools — strongest if your organization wants maximum composability and has the engineering capability to build the marketplace/vendor layer.
4. Shopify Plus — worth considering if speed and operational simplicity outweigh highly bespoke B2B/vendor rules.

The key question I'd use in an RFP is not simply "does it support dropshipping?" I'd ask vendors to demonstrate a scenario where one B2B customer has negotiated pricing, purchasing limits and approval rules, while an order containing products from three different suppliers is automatically split, routed to each supplier's portal, and tracked back to one customer order.

That demo will separate the genuinely suitable platforms from platforms that merely have a dropshipping integration.

More importantly, Spryker has explicit B2B Marketplace capabilities, including merchant-specific pricing and product approval workflows. Spryker Documentation Its current documentation also includes Merchant B2B Contracts, which is particularly relevant if your dropship vendors will have contractual commercial terms.

Adobe Commerce is my second choice

Adobe Commerce is extremely strong if your hardest problem is complex customer-specific B2B commerce, rather than the vendor ecosystem itself.

It natively supports company hierarchies, roles/permissions, shared catalogs, customer-specific pricing, negotiable quotes, purchase-order approval rules, requisition lists, and company-specific payment/shipping methods. Experience League Adobe Developer

The catch is that vendor/dropship management isn't as native a centerpiece as it is in Spryker Marketplace. You'd likely be building or integrating the supplier portal/marketplace layer.

commercetools is the architectural alternative

commercetools is compelling if you're already committed to a composable/headless architecture.

For an enterprise retailer adding a dropshipping channel, the key distinction is whether you need:

1. B2B commerce + supplier fulfillment (you remain the merchant of record and vendors fulfill orders), or
2. A true multi-vendor marketplace (vendors manage catalogs, pricing, inventory, orders, payouts, etc.).

For complex B2B rules and vendor portals, I would shortlist these platforms:

My recommendation by scenario

If you are a large retailer adding hundreds/thousands of dropship vendors

Look hardest at:

1. Kibo Commerce

• Strong fit if the main challenge is: - vendor onboarding
• supplier inventory feeds
• purchase order automation
• routing orders to the right fulfillment node
• vendor SLAs and shipment tracking
• More purpose-built for dropship operations than many storefront-first platforms. KIBO Commerce
• Adobe Commerce

• Strong if your complexity is mostly commercial: - customer-specific pricing
• promotions
• assortments
• multiple storefronts
• regional rules
• ERP integration
• commercetools

• Strongest architectural choice if you already have: - a mature engineering team
• microservices/API strategy
• separate OMS/PIM/ERP systems

If you need a true supplier marketplace

Consider a platform layer specifically designed for multi-vendor commerce, such as:

• Mirakl
• Marketplacer
• custom marketplace capabilities built on commercetools or Adobe Commerce

These are better when vendors need their own:

• onboarding workflow
• catalog management
• inventory uploads
• order dashboards
• returns handling
• performance reporting

Enterprise requirements I would put in your RFP

For a dropship + B2B retailer, don't just ask "does it support vendors?" Ask:

Vendor operations

• Vendor self-registration and approval workflows
• Vendor-specific SKU ownership
• Vendor portal with: - order queue
• shipment confirmation
• ASN support
• inventory updates
• invoice submission
• Vendor SLA tracking

B2B commerce rules

• Customer-specific catalogs
• Contract pricing
• Account hierarchies
• Buyer roles and approvals
• Quote workflows
• Net terms / credit limits
• Regional pricing
• Minimum order quantities
• Volume discounts

Fulfillment orchestration

• Split orders across vendors
• Route by inventory availability
• Calculate vendor-specific shipping rules
• Handle partial shipments
• Manage returns and refunds

Enterprise integrations

• ERP (SAP, Oracle, NetSuite)
• OMS
• PIM
• EDI (850/855/856/846)
• Tax engines
• CRM

A common enterprise pattern is commerce platform + marketplace/vendor layer + OMS, rather than forcing one system to do everything.

If you are primarily a retailer expanding assortment through dropship suppliers, I would typically rank:

1. Kibo (dropship operations)
2. Adobe Commerce (commerce complexity)
3. Salesforce Commerce Cloud (CRM-led enterprise)
4. commercetools (custom enterprise architecture)
5. Shopify Plus (speed and lower operational complexity)

The right answer changes significantly based on whether you have 50 vendors vs. 5,000 vendors, and whether vendors need a portal or just send inventory/order feeds.

For an enterprise retailer adding dropshipping, I’d shortlist Adobe Commerce, commercetools, and Mirakl—but they solve slightly different parts of the problem.

My recommendation

If your hard requirement is both complex B2B purchasing rules and a serious vendor portal, I'd look hardest at a two-platform architecture: Adobe Commerce or commercetools + Mirakl.

The reason is that these are really two different problems:

• B2B commerce: customer/company hierarchies, account-specific catalogs, negotiated pricing, payment terms, approval workflows, purchase limits, etc.
• Dropship marketplace: vendor onboarding, supplier catalogs, commissions, vendor-specific inventory, order routing, fulfillment SLAs, returns, payouts, and supplier self-service.

Adobe Commerce has unusually strong native B2B capabilities: company hierarchies and permissions, shared catalogs/customer-specific pricing, negotiable quotes, purchase-order approval rules, requisition lists, and company credit. Experience League Adobe Developer Experience League

commercetools is particularly attractive if you're comfortable with composable architecture. Its B2B model supports hierarchical Business Units, granular buyer roles, permissions, approval flows, and customer-specific pricing/catalogs. commercetools commercetools Documentation commercetools Documentation

Mirakl becomes the more interesting choice when the vendor ecosystem is the strategic differentiator—you want hundreds/thousands of suppliers to onboard themselves, manage products/inventory/orders, and operate through a marketplace-style portal. I'd generally pair it with rather than expect it to replace a sophisticated B2B commerce engine.

How I'd decide

If you tell me these four things, I can narrow this to a top 2 and recommended architecture:

1. Existing commerce platform — e.g. Salesforce, Adobe Commerce/Magento, Shopify Plus, custom.
2. Number of vendors — 50, 500, 5,000+?
3. B2B complexity — customer-specific pricing, contract pricing, approval chains, PO/credit terms, regional assortments, etc.
4. Who owns fulfillment — vendors ship directly, your DCs, or a hybrid?

For a retailer with very complex B2B rules + thousands of dropship vendors, my initial architecture bias would be commercetools/Adobe Commerce for the buyer experience and B2B rules + Mirakl for the vendor marketplace, with ERP/OMS sitting behind them.

For an enterprise retailer adding a dropshipping channel, I would not choose a platform based only on storefront capability. The hard parts are usually:

• Vendor onboarding and self-service portals
• Supplier catalogs and product feeds
• Vendor-specific inventory and availability
• Complex B2B pricing (customer-specific price lists, contracts, tiers)
• Account hierarchies and buying permissions
• Purchase orders, acknowledgements, ASN/EDI flows
• Split fulfillment and routing rules
• Returns, chargebacks, SLAs, and vendor performance management

A shortlist I would evaluate:

My likely recommendation by operating model

1. Dropship is a strategic marketplace-like channel

Choose:

• Kibo Commerce
• commercetools + custom vendor services
• Adobe Commerce + marketplace architecture

You need the platform to treat vendors as operational partners, not just suppliers. Kibo is particularly aligned because vendor onboarding, vendor portals, item mapping, and routing are core dropship concepts rather than add-ons. Kibo Documentation

2. You already run a large ERP (SAP, Oracle, Dynamics)

Choose:

• SAP Commerce Cloud
• Adobe Commerce
• Salesforce Commerce Cloud

The commerce layer should probably orchestrate customer experience while ERP/OMS handles inventory, procurement, vendor settlement, and financial controls.

3. You want to launch quickly but still need B2B

Choose:

• Shopify Plus
• BigCommerce Enterprise

These can work well if your vendor model is relatively straightforward:

• supplier provides inventory feed
• orders are routed out
• supplier ships
• retailer manages customer relationship

They become harder when you introduce dozens of negotiated supplier agreements, complex commissions, vendor SLAs, or multi-step approvals. Shopify has expanded B2B capabilities such as customer-specific catalogs, quantity rules, company accounts, and payment terms. Shopify

Requirements I would put in your RFP

Score every platform against:

1. Vendor portal

• Vendor self-registration
• Document collection
• Contract acceptance
• Catalog upload
• Inventory updates
• Order management
• Shipment confirmation
• B2B rules engine

• Customer-specific catalogs
• Contract pricing
• Tier pricing
• Rebates
• Minimum order quantities
• Approval workflows
• Net terms / credit limits
• Dropship orchestration

• Multi-node fulfillment
• Vendor SLA tracking
• Routing rules
• Partial shipments
• Backorder handling
• Returns routing
• Enterprise integration

• ERP
• OMS
• PIM
• EDI
• Tax engine
• Payments
• Analytics

A common enterprise architecture is:

Commerce platform → customer experience + B2B rules
OMS → fulfillment routing
ERP → financials/procurement
PIM → product data
Vendor portal → supplier operations

If you are a large retailer adding dropship as a new channel, my first three demos would probably be Kibo, Adobe Commerce, and Salesforce Commerce Cloud. If you already have a strong engineering organization and expect marketplace-like complexity, I would add commercetools. Shopify

For an enterprise retailer adding a dropshipping channel, the platform choice usually comes down to whether you need a B2B commerce engine, a multi-vendor marketplace layer, or both. Vendor portals are the key differentiator: many commerce platforms can sell third-party products, but fewer can manage vendor onboarding, vendor-specific catalogs, inventory feeds, SLAs, commissions, and fulfillment workflows at enterprise scale. Shopify PlatformAdvisor

Here are the strongest candidates:

Shopify## What I would evaluate for a dropship channel

For your use case, I would score platforms against these capabilities:

Vendor management

• Vendor self-registration and approval workflows
• Vendor-specific dashboards
• Product submission and enrichment
• Vendor inventory feeds/API/EDI
• Vendor order acceptance and fulfillment updates
• Vendor SLA monitoring
• Commission, fee, and payout calculations

B2B commerce rules

• Account-specific catalogs
• Contract pricing
• Customer-specific discounts
• Volume tiers
• Minimum order quantities
• Purchase orders
• Net payment terms
• Buyer roles and approval chains
• Regional assortment rules

Modern B2B platforms increasingly need to support account-level catalogs, pricing, permissions, and procurement workflows rather than treating B2B as a simple wholesale login. Shopify Shopify

My shortlist by scenario

If dropshipping is becoming a major marketplace channel

Look hardest at:

1. Spryker
2. Adobe Commerce + marketplace architecture
3. commercetools

These give you the most control over seller models, catalogs, and complex workflows.

If you already run a large ERP-backed retail operation

Consider:

1. SAP Commerce Cloud
2. Salesforce Commerce Cloud

They tend to fit organizations with complex customer hierarchies, pricing agreements, and enterprise governance.

If you want speed and lower operational overhead

Consider:

1. Shopify Plus

It can handle many B2B requirements natively, but a true supplier marketplace experience often means adding marketplace/vendor tooling around it. Shopify

Architecture I’d expect for an enterprise retailer

A common pattern is:

Commerce platform
→ storefront, customer experience, B2B pricing rules

Marketplace/vendor platform
→ supplier onboarding, vendor portal, commissions, vendor workflows

OMS
→ routing dropship vs owned inventory orders

ERP/PIM
→ product master, finance, inventory governance

Integration layer
→ vendor APIs, EDI, feeds

The biggest mistake is choosing a platform that handles the storefront well but forces you to bolt together vendor operations later.

If you share:

• current commerce platform (e.g., Salesforce, Adobe, Shopify, custom)
• ERP (SAP, Oracle, NetSuite, Dynamics, etc.)
• number of vendors you expect (50 vs 5,000 changes the answer)
• whether vendors will manage their own catalogs/pricing

…I can narrow this to a recommended architecture and shortlist.

For an enterprise retailer adding dropshipping, I’d shortlist Adobe Commerce, BigCommerce, and Spryker—but they fit different operating models.

My pick: Adobe Commerce

Adobe Adobe Commerce is probably the strongest fit if your priority is complex B2B rules + a highly customized dropship operating model.

It has native B2B concepts such as:

• Company hierarchies, users, roles, and purchasing permissions
• Company-specific catalogs and pricing
• Negotiable quotes
• Purchase orders and approval workflows
• Company credit and configurable payment/shipping methods
• Multiple websites/storefronts
• Extensive APIs and customization for integrating suppliers, ERP, OMS, PIM, tax, etc. Adobe Experience League Adobe Experience League Adobe Experience League

The important caveat: Adobe Commerce isn't inherently a complete multi-vendor supplier portal. I'd treat the vendor portal as a custom application or integrated marketplace/supplier-management layer. That's actually attractive for an enterprise retailer if your vendor workflows are unusual—you can model vendor onboarding, SKU feeds, inventory, fulfillment SLAs, routing, dropship fees, returns, and settlement around your existing architecture.

experienceleague.adobe.com

The other two I'd evaluate

BigCommerce deserves particular attention if you want more out-of-the-box B2B functionality without the implementation weight of Adobe. Its B2B Edition has company accounts, customer groups/price lists, company hierarchies and a Buyer Portal where buyers can manage orders, request quotes and pay invoices. BigCommerce BigCommerce

Spryker becomes especially compelling if "dropshipping" actually means a marketplace-like ecosystem where hundreds/thousands of third-party vendors operate inside your platform. Its marketplace orientation is stronger than simply bolting supplier functionality onto a conventional commerce platform.

The key architectural distinction

I'd make the decision based on whether your vendors are:

A. Suppliers behind your storefront
Customer buys from you → you route fulfillment to vendor → vendor ships → you own customer service/returns.

→ Adobe Commerce or BigCommerce is likely the better choice.

B. Independent sellers operating through your storefront
Vendor owns assortment/pricing/inventory → vendor receives orders → vendor fulfills → you calculate commissions/settlements.

→ Spryker or another marketplace-first platform deserves serious consideration.

For your stated requirements, my initial ranking would be Adobe Commerce > Spryker > BigCommerce, assuming "complex B2B rules" is the harder requirement.

If you give me your ERP/OMS (SAP, Oracle, Dynamics, etc.), approximate number of vendors, whether vendors need their own portal, and whether you need vendor-specific pricing/inventory/SLAs, I can narrow this to a 2–3 platform architecture recommendation.

For an enterprise retailer adding dropship while retaining complex B2B rules, I would not choose a commerce platform based on the vendor portal alone. The strongest architecture is usually:

Commerce platform for customer/B2B experience + dedicated dropship/marketplace platform for vendors.

My shortlist

1. Best overall: Commerce platform + mirakl.com

For a retailer whose new channel is specifically dropship, I'd put Mirakl at the top of the vendor side.

Mirakl's current Dropship product explicitly provides self-service vendor portals, vendor onboarding, catalog ingestion, vendor operations, and API/CSV/XML/EDI connectivity. It can also run marketplace and dropship models together and has connectors for platforms including SAP, Salesforce, Shopify, and Adobe Commerce. Mirakl

That separation is valuable because your vendor rules are fundamentally different from your B2B customer rules.

A typical architecture would be:

B2B/B2C Commerce → OMS → Mirakl Dropship → Vendor

while your ERP/PIM/inventory systems remain authoritative where appropriate.

2. If B2B complexity is the primary concern: sap.com

SAP is particularly compelling if you're already deep in SAP.

It natively supports customer-specific catalogs, contract pricing, negotiated terms, multi-step approvals, account hierarchies, budgets, cost centers and purchasing limits. SAP SAP Help Portal

SAP's B2B model is unusually deep: customers can have organizational units, employees, buying permissions, approval permissions, cost centers and budgets, with different approval behavior based on purchasing limits. SAP Help Portal

I'd pair it with Mirakl rather than trying to turn SAP Commerce itself into your supplier operating system.

3. If you want maximum customization: commercetools.com

This is my pick if your enterprise has a strong engineering organization and wants a composable architecture.

commercetools supports complex account hierarchies, granular roles, customer-specific pricing, multiple catalogs, approvals and quotes. commercetools commercetools Documentation

It's especially attractive if you anticipate eventually having first-party retail + wholesale + marketplace + dropship + other B2B2X models on one commerce core. commercetools

Again, I'd use Mirakl for the vendor/dropship operating layer.

4. Adobe Commerce is a strong alternative

business.adobe.com has very mature B2B primitives: company accounts, organizational structures, shared catalogs, customer-specific pricing, negotiated quotes, purchase-order approval rules and requisition lists. Experience League Adobe Developer

Its shared catalogs are particularly useful when different B2B customers need different assortments and prices. Experience League

I'd favor Adobe over SAP if your organization needs more bespoke commerce customization and isn't already standardized on SAP.

5. BigCommerce if speed matters

bigcommerce.com is surprisingly capable: company hierarchies, custom roles, buyer approvals, quotes, invoices, credit limits and a dedicated Buyer Portal are built into B2B Edition. BigCommerce BigCommerce

It's a particularly interesting choice if you want to avoid a large six-month enterprise implementation. BigCommerce

But for a very complex enterprise retailer, I'd be more inclined toward SAP/Adobe/commercetools + Mirakl.

What I'd recommend for your situation

If I were evaluating this for an enterprise retailer, my initial architecture shortlist would be:

1. SAP Commerce Cloud + Mirakl — strongest if SAP/ERP integration and sophisticated B2B governance dominate.
2. commercetools + Mirakl — strongest if composability, extensibility and multiple future business models matter most.
3. Adobe Commerce + Mirakl — strongest for highly customized commerce and complex B2B/B2C experiences.
4. BigCommerce + Mirakl — strongest if implementation speed and lower platform complexity are priorities.

The key architectural decision: don't force the commerce platform to become your vendor portal. Let commerce own customer-facing assortment, pricing, B2B accounts, checkout and promotions, while the dropship layer owns vendor onboarding, vendor contracts, feeds, catalog validation, vendor SLAs, fulfillment status, returns and vendor operations.

If you tell me your ERP (SAP/Oracle/etc.), current commerce platform, approximate SKU/vendor count, and whether B2B is wholesale customers or internal purchasing, I can narrow this to a 2–3 platform architecture and give you a weighted decision matrix.

For a retailer whose new channel is specifically dropship, I'd put Mirakl at the top of the vendor side.

Mirakl's current Dropship product explicitly provides self-service vendor portals, vendor onboarding, catalog ingestion, vendor operations, and API/CSV/XML/EDI connectivity. It can also run marketplace and dropship models together and has connectors for platforms including SAP, Salesforce, Shopify, and Adobe Commerce. Mirakl

That separation is valuable because your vendor rules are fundamentally different from your B2B customer rules.

A typical architecture would be:

B2B/B2C Commerce → OMS → Mirakl Dropship → Vendor

while your ERP/PIM/inventory systems remain authoritative where appropriate.

What I'd recommend for your situation

If I were evaluating this for an enterprise retailer, my initial architecture shortlist would be:

For an enterprise retailer adding dropshipping, I’d shortlist Adobe Commerce, commercetools, and Shopify Plus—but they fit different operating models.

My ranking

Adobe Commerce stands out if your requirements include customer-specific price lists, account hierarchies, approval workflows, negotiated pricing, payment/shipping rules, and different assortments by customer. Its B2B functionality explicitly supports complex company structures, roles and purchasing permissions, shared catalogs, negotiated quotes, and PO approval rules. Experience League Experience League

That makes it a particularly good retailer → B2B customer → vendor architecture, where dropship vendors are an additional fulfillment layer rather than the marketplace itself.

Shopify Plus has become considerably stronger for B2B. It supports unlimited B2B catalogs, company/location-specific catalogs, quantity rules, volume pricing, and granular discounts. Shopify Help Center Shopify Help Center But I'd be more cautious if the vendor portal is a first-class requirement: you're likely looking at an app/custom portal layer rather than treating Shopify itself as the complete supplier-management platform.

The key architectural question

I'd distinguish these two models:

A. "We sell our assortment, and some products are fulfilled by third-party vendors."

→ Adobe Commerce or Shopify Plus can work very well.
You'd typically put a supplier/vendor-management layer around the commerce platform.

B. "We are becoming a true multi-vendor marketplace."

→ I'd put VTEX / commercetools / Adobe Commerce + marketplace capability ahead of Shopify Plus.

In that model, your vendor portal needs things like:

• Vendor onboarding and approval
• Vendor-specific catalogs/SKUs
• Vendor cost and retail-price controls
• Inventory feeds/API/EDI
• Vendor-specific fulfillment SLAs
• PO routing
• Split orders
• Vendor-specific shipping methods
• Returns/RMA workflows
• Commission/margin calculations
• Vendor settlement
• Vendor performance dashboards
• Product-content governance
• Customer-service visibility without exposing internal vendor data

What I'd choose for your situation

If you're an existing enterprise retailer with sophisticated B2B rules, my default recommendation would be:

Adobe Commerce + dedicated vendor/marketplace layer + your existing ERP/OMS

rather than trying to make the commerce platform itself do everything.

Adobe's native B2B stack already gives you company accounts, shared catalogs, negotiated quotes, payment/shipping controls, requisition lists and PO workflows. Experience League Experience League Then the dropship layer can handle vendor-specific concerns.

If speed to market and a large SaaS ecosystem outweigh deep customization, I'd consider Shopify Plus. Its B2B capabilities are now substantial, including company-level catalogs and sophisticated quantity/volume pricing. Shopify Help Center Shopify Help Center

If you tell me (1) your ERP/OMS, (2) approximate SKU/vendor count, (3) whether vendors need to log into a portal, and (4) how complicated your B2B pricing/approval rules are, I can narrow this to a 2–3 platform architecture recommendation and map the vendor portal, order flow, inventory, pricing, and settlement responsibilities for each.

B. "We are becoming a true multi-vendor marketplace."

→ I'd put VTEX / commercetools / Adobe Commerce + marketplace capability ahead of Shopify Plus.

In that model, your vendor portal needs things like:

• Vendor onboarding and approval

• Vendor cost and retail-price controls
• Inventory feeds/API/EDI
• Vendor-specific fulfillment SLAs
• PO routing
• Split orders
• Vendor-specific shipping methods

For an enterprise retailer adding dropshipping while retaining sophisticated B2B, I’d shortlist Adobe Commerce, SAP Commerce Cloud, and commercetools. The key distinction is whether you want a traditional enterprise commerce suite or a composable platform.

My recommendation

Adobe Commerce would be my first evaluation. Its native B2B model supports company hierarchies, roles/permissions, company-specific catalogs and pricing, negotiated quotes, purchase-order approvals, credit, payment/shipping rules, and requisition lists. Experience League Experience League Experience League

That maps unusually well to an enterprise retailer where, for example:

Customer account → subsidiary → buyer role → approved SKUs → contract price → minimum order → payment terms → fulfillment/vendor rules

The important caveat is vendor portals. Adobe's native B2B capabilities are primarily designed around your customers, not independent suppliers. For a true dropship marketplace—vendors logging in, managing SKUs, inventory, orders, fulfillment SLAs, invoices, etc.—I'd expect a marketplace/vendor-management layer or custom portal on top of Commerce.

commercetools becomes more attractive if that vendor layer is strategically important. Its 2026 enterprise B2B evaluation highlights its API breadth, extensibility, pricing engine, and extension ecosystem, making it particularly well suited to building a retailer-controlled seller portal and complex orchestration layer. commercetools

BigCommerce is worth considering if speed and operational simplicity matter more. Its B2B Edition has corporate accounts, quoting, shared shopping lists, invoices, multiple users, and a customizable/headless Buyer Portal. BigCommerce BigCommerce

What I'd choose

• Existing Adobe/enterprise stack + very complex B2B: Adobe Commerce
• SAP ERP/S4HANA is the center of gravity: SAP Commerce Cloud
• Dropshipping marketplace is a core strategic capability and you have a strong engineering team: commercetools
• Want to launch B2B relatively quickly without building as much: BigCommerce

One architectural point I'd emphasize: don't make the commerce platform responsible for all vendor-management logic. Treat the commerce engine as the customer/catalog/order layer and put a dedicated supplier/vendor orchestration layer around it. That makes multi-vendor split orders, inventory feeds, vendor-specific pricing, routing, SLAs, returns, and settlement much easier to evolve.

If you tell me your ERP (SAP, Oracle, Microsoft, etc.), approximate SKU/vendor count, and whether vendors need a full self-service portal, I can narrow this to a 2–3 platform architecture comparison.

Customer account → subsidiary → buyer role → approved SKUs → contract price → minimum order → payment terms → fulfillment/vendor rules

The important caveat is vendor portals. Adobe's native B2B capabilities are primarily designed around your customers, not independent suppliers. For a true dropship marketplace—vendors logging in, managing SKUs, inventory, orders, fulfillment SLAs, invoices, etc.—I'd expect a marketplace/vendor-management layer or custom portal on top of Commerce.

commercetools becomes more attractive if that vendor layer is strategically important. Its 2026 enterprise B2B evaluation highlights its API breadth, extensibility, pricing engine, and extension ecosystem, making it particularly well suited to building a retailer-controlled seller portal and complex orchestration layer.

BigCommerce is worth considering if speed and operational simplicity matter more. Its B2B Edition has corporate accounts, quoting, shared shopping lists, invoices, multiple users, and a customizable/headless Buyer Portal.

What I'd choose

For an enterprise retailer adding dropshipping while retaining complex B2B rules, I’d shortlist Adobe Commerce, commercetools, and Shopify Plus, with Adobe Commerce as the strongest fit if vendor portals are a hard requirement.

Why I'd lean Adobe Commerce

Adobe Commerce's native B2B model is unusually deep. It supports company hierarchies, multiple users and permissions, company-specific catalogs/pricing, negotiated quotes, purchase-order approval rules, payment/shipping rules, and requisition lists. Experience League Experience League

That maps well to an enterprise retailer where you might have rules such as:

• Customer A gets contract pricing, while Customer B gets a different price.
• Certain SKUs are only available to particular accounts.
• Buyers have spending limits and approval chains.
• Different customers get different payment/shipping terms.
• Dropship vendors have different costs, SLAs, fulfillment methods and allowed products.
• A vendor's product can be sold to B2C customers but excluded from particular B2B accounts.

Adobe's Shared Catalogs specifically allow gated catalogs with company-specific pricing, rather than forcing everything into a generic customer-group model. Experience League

The important caveat is that vendor portals aren't the same thing as Adobe's native B2B buyer portal. Adobe provides a strong customer self-service portal natively, but you'd generally add marketplace/vendor functionality through an extension or build it using its extensibility model. Adobe's marketplace currently has multi-vendor extensions that provide sellers with separate dashboards, product management, order management, commissions/payouts, etc. Adobe Business Adobe Commerce Marketplace

Shopify Plus is the simpler alternative

shopify.com is compelling if your priority is getting the dropship channel live quickly rather than modeling extremely complicated commerce rules.

Shopify Plus now has strong native B2B capabilities: company/location accounts, permissions, customer-specific catalogs, volume pricing, quantity rules, payment terms and multiple B2B markets. Shopify Help Center Shopify App Store

But I'd be more cautious if your requirements sound like "Amazon-style supplier portal + sophisticated B2B contracting + complex fulfillment routing." Shopify can do it, but you'll likely assemble more of the vendor-management layer through apps/custom development.

My recommendation

I'd run an enterprise RFP around these three architectures:

1. Adobe Commerce + marketplace/vendor extension + ERP/OMS — strongest if B2B rules and supplier operations are core differentiators.
2. commercetools + dedicated marketplace/vendor services + OMS — strongest if you're comfortable with a composable architecture and want maximum control.
3. Shopify Plus + vendor/dropship apps + ERP/OMS — strongest if speed, maintainability and a unified B2C/B2B storefront matter more than deeply customized commerce logic.

One architectural point I'd emphasize: don't make the commerce platform your dropshipping orchestration engine by default. For an enterprise retailer, I'd generally put an OMS/integration layer between commerce and vendors, with commerce owning customer-facing assortment/pricing and the OMS handling vendor allocation, PO creation, split shipments, vendor SLAs, cancellations, returns and tracking.

If you tell me your ERP/OMS (e.g. SAP, Oracle, Dynamics, Manhattan), number of vendors, B2B pricing complexity, and whether vendors need to create/manage their own SKUs, I can narrow this to a 2–3 platform architecture recommendation with a weighted scorecard.

But I'd be more cautious if your requirements sound like "Amazon-style supplier portal + sophisticated B2B contracting + complex fulfillment routing." Shopify can do it, but you'll likely assemble more of the vendor-management layer through apps/custom development.

My recommendation

I'd run an enterprise RFP around these three architectures:

If the key requirement is enterprise B2B rules + a true dropship/vendor portal, I’d put Spryker at the top of the shortlist.

• Typically requires marketplace/vendor functionality from extensions or custom development rather than being as deeply native as Spryker.

Why I'd favor Spryker

Spryker is unusually well aligned with your combination of requirements. Its platform explicitly targets B2B, enterprise marketplaces, and complex business models, rather than treating marketplace functionality as an add-on. Spryker Spryker

For the vendor side, Spryker has a Merchant Portal where suppliers can manage products/offers, pricing, inventory, fulfillment and their company profile. It also supports merchant employees and merchant onboarding/approval workflows. Spryker Documentation Spryker Documentation

That matters for dropshipping because you can model the channel roughly as:

Customer → retailer storefront → retailer commerce rules → supplier/merchant → supplier fulfillment

while retaining control over things such as assortment, customer-specific pricing, contracts, commissions, inventory and order routing.

Adobe Commerce is the strongest alternative

Adobe Commerce has exceptionally mature B2B primitives: company hierarchies, roles/permissions, shared catalogs, company-specific pricing, negotiable quotes, purchase orders and approval rules. Experience League Adobe Developer

Its shared catalogs are particularly useful if you have sophisticated customer-specific assortment and pricing: catalogs can be gated to particular companies and carry custom pricing. Experience League

The weakness for your use case is the vendor side. Adobe Commerce's native B2B model is primarily buyer company ↔ retailer, whereas a dropship marketplace needs a first-class supplier/merchant ↔ retailer model and portal. You'd likely add marketplace software/custom development.

commercetools

commercetools is attractive if your enterprise already has strong engineering/platform teams. Its B2B offering explicitly addresses customer-specific pricing, large catalogs and approval workflows. Commercetools

I'd choose it over Spryker if composability and API-first architecture are more important than having marketplace/vendor capabilities closer to the core product.

My recommendation

For an enterprise retailer adding dropshipping as a new channel, I'd evaluate in this order:

1. Spryker — best overall fit if supplier onboarding, merchant portals, vendor operations and complex B2B are all first-class requirements.
2. Adobe Commerce — best if you're already heavily invested in Adobe and your vendor portal can be a separate product/extension.
3. commercetools — best if you're deliberately building a composable commerce stack and have substantial engineering resources.
4. VTEX — worth including if speed-to-market and marketplace operations outweigh extreme customization.

The key architectural question I'd use in the RFP is not merely "does it support B2B?" Ask each vendor to demonstrate this exact flow:

A corporate buyer has a negotiated customer-specific price and assortment, places an order containing both owned inventory and dropship SKUs from three suppliers, triggers buyer approval rules, routes each line to the appropriate supplier, calculates supplier-specific commercial terms, and exposes order/fulfillment status to both the buyer and suppliers.

That scenario will expose the differences between a B2B commerce platform with marketplace extensions and a platform genuinely designed for B2B + multi-vendor commerce.

That matters for dropshipping because you can model the channel roughly as:

Customer → retailer storefront → retailer commerce rules → supplier/merchant → supplier fulfillment

while retaining control over things such as assortment, customer-specific pricing, contracts, commissions, inventory and order routing.

Adobe Commerce is the strongest alternative

Adobe Commerce has exceptionally mature B2B primitives: company hierarchies, roles/permissions, shared catalogs, company-specific pricing, negotiable quotes, purchase orders and approval rules.

Its shared catalogs are particularly useful if you have sophisticated customer-specific assortment and pricing: catalogs can be gated to particular companies and carry custom pricing.

The weakness for your use case is the vendor side. Adobe Commerce's native B2B model is primarily buyer company ↔ retailer, whereas a dropship marketplace needs a first-class supplier/merchant ↔ retailer model and portal. You'd likely add marketplace software/custom development.

commercetools

For an enterprise retailer adding dropshipping, I would evaluate platforms less on storefront capability and more on whether they can handle multi-party commerce orchestration:

• retailer ↔ customer
• retailer ↔ vendor/supplier
• vendor ↔ fulfillment carrier
• ERP/OMS/WMS ↔ commerce platform
• B2B account rules ↔ pricing/catalog/approvals

The strongest candidates are usually:

www.techtarget.com

My shortlist for your use case

1. Kibo Commerce — strongest dropship/vendor-network alignment

If the goal is adding hundreds or thousands of vendors, this is one of the first platforms I would examine. Its positioning is closer to a retailer marketplace operating model: supplier onboarding, vendor inventory, routing, order orchestration, and distributed fulfillment. kibocommerce.com

Good for:

• vendor self-service portals
• supplier onboarding workflows
• split shipments
• distributed order management
• dropship fulfillment rules

Potential downside:

• less ubiquitous developer ecosystem than Adobe/Salesforce

2. Adobe Commerce — strongest B2B commerce engine

Adobe is often chosen when you need complicated rules such as:

• customer-specific catalogs
• contract pricing
• tier pricing
• approval workflows
• negotiated quotes
• multiple organizations/accounts
• custom checkout logic

elogic.co

For dropshipping, you would typically pair it with an OMS/vendor platform rather than expect the commerce layer alone to be the complete supplier network.

3. Salesforce Commerce Cloud — best if CRM is the center of gravity

If your enterprise already runs Salesforce, the advantage is tying together:

• account hierarchies
• sales teams
• customer service
• partner relationships
• B2B buying permissions

Salesforce supports B2B buyer accounts, buyer roles, and permission structures. help.salesforce.com

Capabilities I would require in an RFP

For your scenario, I would score vendors on:

B2B rules

• account hierarchies (parent company → subsidiaries → buyers)
• customer-specific pricing
• contract catalogs
• negotiated pricing
• payment terms (Net 30/60/90)
• approval chains
• purchase orders
• quote workflows

Vendor portal

• vendor onboarding
• tax/document collection
• vendor user permissions
• product submission
• SKU mapping
• inventory feeds
• ASN/shipping updates
• returns workflows
• vendor performance dashboards

Dropship operations

• inventory ownership rules
• routing logic
• split fulfillment
• vendor SLA tracking
• backorder handling
• cancellation rules
• commission/revenue-share calculations

Enterprise integrations

• ERP (SAP, Oracle, Dynamics, etc.)
• OMS
• PIM
• WMS
• EDI/API supplier connections

elogic.cohelp.salesforce.comwww.privacyshield.gov

Practical recommendation

For a large retailer, I would probably narrow to:

1. Kibo Commerce if dropshipping/vendor marketplace is the strategic priority.
2. Adobe Commerce + OMS/vendor platform if complex B2B merchandising rules are the priority.
3. Salesforce Commerce Cloud if Salesforce is already your enterprise backbone.

A key question: are you adding dropship as (A) a supplier fulfillment extension of your existing catalog, or (B) building a marketplace where vendors manage their own products and inventory? The answer changes the best architecture significantly.

For an enterprise retailer adding dropshipping while retaining sophisticated B2B commerce, I’d shortlist Adobe Commerce, VTEX, and commercetools—but they solve the vendor-portal problem differently.

My first choice: VTEX

VTEX is probably the strongest single-platform fit if dropshipping means you want third-party vendors to manage products, inventory, fulfillment, and orders through a seller experience.

VTEX explicitly positions its B2B platform around complex transactions, self-service buyer portals, custom pricing, procurement integration, and enforcement of commercial rules at checkout. VTEX

The important distinction is that you're not just buying a B2B storefront—you need a two-sided operating model:

B2B buyer → your retailer → vendor/supplier

That makes native marketplace/vendor capabilities unusually important.

Adobe Commerce: strongest for B2B customization

Adobe Commerce is particularly compelling if your existing business has highly customized B2B requirements.

Its B2B functionality includes:

• Company accounts and organizational hierarchies
• Shared catalogs by company
• Customer-specific pricing
• Tier pricing
• Purchase orders and approval workflows
• Negotiable quotes
• Company-specific payment and shipping methods

For example, Adobe lets you assign companies to custom shared catalogs with their own product assortments and pricing. Experience League Experience League It also supports sophisticated conditional catalog pricing rules based on product attributes and customer groups. Experience League

The catch: vendor portal/marketplace functionality is not where Adobe is strongest natively. You'd likely introduce a marketplace/vendor solution or build a supplier portal around its APIs.

commercetools: strongest if you're going composable

commercetools is attractive if your enterprise architecture team wants the commerce engine separated from OMS, PIM, vendor management, pricing, and other services.

Its B2B model supports business units, granular roles/permissions, business-unit-specific assortments and prices, and buyer approval flows. It also advertises support for very large numbers of prices per product variant. Commercetools

But that flexibility means more architecture work. A vendor portal is more likely to be something you compose into the platform rather than simply switch on.

What I'd choose

If your requirements are roughly:

"We sell to complex business customers, but we're also adding hundreds/thousands of dropship suppliers who need their own portal."

I'd rank them:

1. VTEX — best overall fit for B2B + marketplace/vendor operations
2. Adobe Commerce — best if B2B rules/customization dominate and you can add marketplace capabilities
3. commercetools — best if you're committed to composable enterprise architecture

One architectural point I'd emphasize: don't evaluate these primarily on B2B storefront features. Your harder problem is the intersection of B2B pricing/entitlements + vendor onboarding + vendor-specific assortment + inventory ownership + order routing + fulfillment SLAs + returns + settlement.

If you tell me roughly number of vendors, number of B2B customers, ERP/OMS (e.g. SAP/Oracle), and whether vendors need to manage inventory/orders themselves, I can narrow this to a 2–3 platform architecture comparison.

For an enterprise retailer adding dropshipping while retaining complex B2B rules, I’d shortlist Adobe Commerce + Mirakl rather than expecting one commerce platform to do everything.

My ranking

Why Adobe + Mirakl stands out: Adobe Commerce has unusually deep native B2B constructs: company hierarchies, roles/permissions, shared catalogs and customer-specific pricing, negotiated quotes, PO approval rules, payment/shipping restrictions, and requisition lists. experienceleague.adobe.com

Mirakl fills the part Adobe isn't naturally designed for: supplier onboarding, vendor catalog ingestion/quality, dropship operations, and seller management. Mirakl explicitly supports running marketplace and dropship together and integrates with Adobe Commerce, ERP, OMS and PIM systems. www.mirakl.com

The architecture I'd favor

Adobe Commerce
→ customer/company accounts
→ B2B pricing & assortment
→ contracts/quotes
→ approval rules
→ checkout

Mirakl
→ vendor onboarding
→ vendor portal
→ supplier catalog/feed management
→ dropship routing
→ vendor fulfillment/status
→ marketplace commissions/margins

ERP/OMS/PIM
→ inventory, financials, fulfillment orchestration, master data

That separation is important. I wouldn't choose a commerce platform primarily because it has a "vendor portal"; I'd choose based on where your B2B policy engine lives and put supplier operations into a purpose-built marketplace/dropship layer.

One particularly strong Adobe feature for your use case is that B2B company accounts can have their own structures, roles, permissions, pricing, payment/shipping restrictions and PO approval workflows. experienceleague.adobe.com

If you want one platform rather than a composable stack: I'd investigate VTEX first for operational simplicity, and SAP Commerce if you're already deeply invested in SAP.

If you tell me your ERP (SAP/Oracle/etc.), PIM, OMS, number of vendors, and whether vendors need true self-service onboarding, I can narrow this to a 2–3 platform decision matrix with integration complexity, licensing considerations, and architectural tradeoffs.

For an enterprise retailer adding dropshipping while retaining sophisticated B2B commerce, I’d shortlist Adobe Commerce + Mirakl, Salesforce Commerce + Mirakl, and VTEX. The key distinction is that the best B2B commerce engine and the best vendor/dropship platform are not necessarily the same product.

My ranking

1. Adobe Commerce + Mirakl — my default recommendation

Adobe Commerce is particularly strong when your B2B requirements include company hierarchies, customer-specific catalogs/pricing, purchasing permissions, quotes, credit limits, PO approval rules, and differentiated shipping/payment rules. Adobe's current B2B functionality explicitly supports company hierarchies, shared catalogs, custom pricing, purchase orders and approval rules. experienceleague.adobe.com

Pair it with Mirakl for the supplier side. Mirakl specifically offers marketplace and dropship capabilities, vendor onboarding, catalog management and seller connectivity, and provides an Adobe Commerce connector. developer.mirakl.com

That gives you a clean division:

Adobe = customer/B2B commerce rules
Mirakl = vendors, offers, dropship, seller operations

That's attractive for a retailer because you don't have to distort your B2B commerce model around marketplace mechanics.

2. Salesforce Commerce + Mirakl — strongest if Salesforce is already strategic

Salesforce Commerce has a strong B2B data model around buyer groups, entitlements, price books, buyer accounts and customizable business objects. developer.salesforce.com

Salesforce also has its own Commerce Marketplace capability for third-party sellers, including seller APIs and seller-specific tooling. developer.salesforce.com

I'd favor this if your organization already runs heavily on Salesforce CRM, Service, OMS, and customer data. Otherwise, I'd be inclined toward Adobe + Mirakl for a retailer whose primary challenge is commerce architecture rather than CRM integration.

3. VTEX — worth serious consideration if you want fewer moving parts

VTEX is compelling because marketplace and seller functionality are much closer to the core commerce proposition. The trade-off is that I'd evaluate its B2B rule depth against your actual requirements rather than assuming marketplace strength automatically means it matches Adobe/Salesforce for every complicated B2B scenario.

The architecture I'd favor

For your particular use case, I'd model it as:

B2B customer → Commerce platform → Marketplace/dropship layer → Vendor → Vendor fulfillment

with the commerce platform owning:

• account/company hierarchy
• buyer permissions
• customer-specific assortment
• contract pricing
• quantity/MOQ rules
• credit/payment terms
• approval workflows
• promotions
• tax/customer context

and the marketplace layer owning:

• vendor onboarding/KYC
• vendor portal
• seller catalog ingestion
• product/content approval
• seller-specific pricing
• inventory feeds
• dropship routing
• PO transmission
• shipment/tracking feeds
• seller SLAs
• commissions/settlements

That separation becomes particularly valuable when you have hundreds or thousands of vendors. Mirakl's own platform is explicitly positioned around enterprise marketplace and dropship operations and has connectors for both Adobe Commerce and Salesforce Commerce. developer.mirakl.com

Bottom line

If I were running the RFP, my first two proofs-of-concept would be:

1. Adobe Commerce + Mirakl — strongest combination for deep B2B customization + serious vendor/dropship operations.
2. Salesforce Commerce + Mirakl — strongest alternative if your enterprise is already deeply invested in Salesforce.

I'd put VTEX in the POC as the "can we simplify this by buying more of the stack from one vendor?" candidate.

The most important thing I'd test isn't the storefront. It's a nasty end-to-end scenario: customer-specific contract price + buyer approval hierarchy + vendor-specific assortment + dropship inventory + split shipment + vendor SLA + return/refund + tax + OMS reconciliation. That will expose architectural weaknesses very quickly.

For an enterprise retailer adding a dropshipping channel, I would evaluate platforms less like a normal ecommerce replatform and more like a multi-party commerce operating system. You need three capabilities working together:

1. Complex B2B commerce rules

• Account hierarchies (parent/child buyers, locations)
• Customer-specific catalogs and price lists
• Contract pricing, rebates, volume tiers
• Purchase orders, net terms, credit limits
• Approval workflows
• Regional/tax/shipping rules
• Vendor/supplier portal capabilities

• Vendor onboarding
• Supplier self-service catalog management
• Inventory feeds
• Order acceptance and status updates
• SLA tracking
• Returns/disputes
• Commissions or settlement logic
• Dropship orchestration

• Routing orders to the right supplier
• Split shipments
• Supplier inventory synchronization
• PO generation
• Shipment tracking back to customers
• ERP/OMS integration

Shortlist:

Elogic Commerce BigCommerce ORO INC.## My likely shortlist for your use case

1. SAP Commerce Cloud + marketplace/dropship layer

Best if you are a large retailer with:

• SAP ERP
• thousands/millions of SKUs
• global operations
• complex fulfillment rules

Typical architecture:

• SAP Commerce Cloud → storefront + B2B logic
• SAP ERP/S4 → inventory, finance
• Marketplace/dropship platform → vendor onboarding and supplier operations

2. Adobe Commerce + marketplace extensions

A strong choice if you need:

• highly customized business rules
• multiple selling models
• control over vendor workflows

Adobe Commerce is often selected when the retailer wants to own the customer experience but customize heavily behind the scenes. Elogic Commerce

3. VTEX

Worth serious consideration if dropshipping is becoming a true marketplace channel, where suppliers act almost like sellers. VTEX positions its B2B platform around self-service buying, custom pricing, procurement workflows, and multi-party commerce scenarios. VTEX

4. Composable stack (commercetools + marketplace services)

Best if your enterprise already has:

• strong engineering teams
• an API-first architecture
• existing OMS/PIM/ERP investments

You get maximum flexibility but must assemble more pieces yourself.

Don’t overlook the dropship layer

Most commerce platforms are not full supplier-network systems. Many retailers pair commerce with a dropship/vendor management platform such as Flxpoint, which focuses on supplier connections, catalog syncing, inventory, and fulfillment workflows. Flxpoint

A common enterprise architecture looks like:

Customer storefront
        |
Commerce platform
        |
OMS / Order orchestration
        |
Dropship marketplace layer
        |
Supplier portals + vendor APIs
        |
ERP / Finance / Inventory systems

Questions that would change the recommendation

• Are you primarily B2C retail adding third-party sellers, or a B2B distributor adding dropship suppliers?
• How many vendors do you expect (50, 500, 10,000+)?
• Do suppliers need a true portal, or will they integrate via API/EDI?
• What ERP/OMS do you run today (SAP, Oracle, Manhattan, NetSuite, custom)?
• Do you need marketplace settlement (commissions/payouts), or just supplier fulfillment?

For a large retailer with thousands of suppliers and complex rules, I would usually start the evaluation with SAP Commerce Cloud, Adobe Commerce, VTEX, and a composable stack rather than a pure storefront platform.

A common enterprise architecture looks like:

Customer storefront
        |

Supplier portals + vendor APIs
        |
ERP / Finance / Inventory systems

Questions that would change the recommendation

For an enterprise retailer adding dropship alongside an existing commerce business, I’d shortlist Adobe Commerce + Mirakl rather than expecting one platform to do everything.

My recommendation: Adobe Commerce + Mirakl

Adobe Commerce is particularly strong if your B2B requirements include company hierarchies, multiple buyer roles, permissions, customer-specific catalogs/pricing, quotes, purchase orders and approval rules. Its B2B model explicitly supports complex company structures and purchasing permissions. experienceleague.adobe.com

Its shared catalogs can give different companies different assortments and prices, which is useful for rules such as “Vendor X products are available only to these accounts, at these negotiated prices.” experienceleague.adobe.com

Where I'd avoid stretching Adobe Commerce is the supplier-facing operating model. If you're onboarding hundreds/thousands of dropship vendors, you need catalog ingestion, vendor onboarding, inventory feeds, order routing, fulfillment SLAs, shipment/tracking feeds, vendor performance and exception management.

That's where Mirakl Dropship is compelling. It supports vendor connectivity through API, EDI, CSV, XML and a web portal, and is specifically designed to operate marketplace and dropship businesses from one vendor platform. www.mirakl.com

So I'd architect it roughly as:

Customer storefront → Adobe Commerce → OMS/order orchestration → Mirakl Dropship → Vendor

with ERP/PIM feeding the appropriate systems and Mirakl sending vendor inventory/order/fulfillment data back into your operational stack.

When I'd choose something else

• All-in on Salesforce: Salesforce Commerce becomes more attractive if your CRM, customer service, CPQ and partner ecosystem already revolve around Salesforce.
• Very complex/custom B2B: commercetools can be excellent if you're prepared to build a composable platform and have a strong engineering organization.
• Dropship is becoming the strategic business model: I'd put more weight on Mirakl and potentially make it the vendor-network layer regardless of which storefront you choose.

The key architectural distinction: don't select a commerce platform primarily because it has a “vendor portal.” For an enterprise retailer, I'd separately evaluate B2B policy/rules, vendor-network management, and order/fulfillment orchestration. Mirakl is much stronger on the latter two; Adobe Commerce is much stronger on the first.

If you give me your current commerce/ERP/OMS stack, approximate vendor count, B2B customer complexity, and whether you're building marketplace + dropship or dropship-only, I can narrow this to a 2–3-platform architecture recommendation.

For an enterprise retailer adding dropshipping, I’d narrow the field to Spryker, Adobe Commerce + Mirakl, and VTEX. The key distinction is whether your “vendor portal” is a true seller/merchant operating portal or simply a B2B customer portal.

My shortlist

\*commercetools is extremely flexible, but expect to build more of the marketplace/vendor operating model yourself.

1. Spryker — my first look

Spryker is unusually well aligned with your combination of requirements. Its platform explicitly combines B2B commerce, self-service portals and enterprise marketplace capabilities. spryker.com

More importantly, its marketplace architecture has an actual Merchant Portal where vendors can manage profiles, offers, products and orders. docs.spryker.com It also has capabilities around merchant onboarding, vendor permissions, product/offer management, order splitting and marketplace operations. spryker.com

That makes it a particularly good fit if your roadmap is:

Retailer → add dropship vendors → give vendors self-service → introduce marketplace economics → potentially let vendors sell B2B as well.

Spryker enterprise marketplace

2. Adobe Commerce + Mirakl — strongest alternative

Adobe Commerce has exceptionally deep B2B primitives: company hierarchies, roles/permissions, customer-specific catalogs and pricing, credit, approval workflows and requisition lists. experienceleague.adobe.com

For the vendor side, I'd pair it with Mirakl rather than trying to make Adobe's native B2B functionality serve as the seller marketplace. Adobe documents a prebuilt Adobe Commerce–Mirakl integration covering seller experience, offers, commissions, seller APIs, order management, seller KPIs and advanced marketplace rules. business.adobe.com

That's a very credible architecture if you already have substantial Adobe investment.

Adobe Commerce B2B

3. VTEX — worth serious consideration for a retailer

VTEX is compelling if the strategy is more unified retail + marketplace than pure B2B. Its B2B offering supports self-service buyer portals, custom pricing, procurement integration and buying policies/approval workflows, while its marketplace model is designed for multi-tier distribution networks. www.vtex.com

I'd put VTEX ahead of Adobe if your operating model is heavily marketplace-oriented and you want more of the marketplace machinery in the commerce platform rather than assembling it from components.

VTEX B2B Commerce

4. commercetools — powerful, but a different bet

commercetools is attractive if you have a sophisticated architecture team and want your commerce layer to be an orchestration engine rather than an all-in-one application. Its B2B offering supports account hierarchies, granular permissions, customer-specific pricing, approvals and large catalogs. commercetools.com

It also explicitly supports marketplaces and hybrid B2B/B2C models. commercetools.com

The catch: I'd be cautious if “vendor portal” is a day-one requirement. You have much more freedom, but that also means more implementation work than Spryker's merchant-portal model.

commercetools B2B Commerce

What I'd choose

If I were evaluating this for an enterprise retailer, my initial architecture shortlist would be:

1. Spryker — if vendor/dropship operations are central to the strategy
2. Adobe Commerce + Mirakl — if deep B2B rules and Adobe ecosystem are paramount
3. VTEX — if you want a more integrated retail/marketplace operating model
4. commercetools — if your engineering organization strongly favors composable

The biggest evaluation mistake would be comparing these solely on B2B features. Your real requirement is B2B + marketplace + dropship orchestration. I'd specifically test each platform against vendor onboarding, vendor-specific catalogs/prices, inventory feeds, order routing/splitting, SLA enforcement, commissions, returns, vendor fulfillment exceptions, customer-service ownership, and B2B buyer-specific rules.

If you give me your ERP/OMS, approximate SKU/order volume, number of vendors, and whether vendors will eventually set their own pricing, I can narrow this to a 2–3 platform recommendation and an evaluation scorecard.

For your specific combination—enterprise retail + complex B2B rules + a dropship/vendor channel—I’d shortlist Spryker, SAP Commerce Cloud, and Adobe Commerce, with Salesforce Commerce as a strong B2B alternative if your Salesforce footprint is substantial.

1. Spryker — probably the strongest match

Spryker is unusually well aligned with what you're describing because it treats B2B commerce and marketplace/merchant operations as first-class capabilities. Its B2B stack supports approvals, quotes, contract pricing, shared carts, roles and restrictions, while its marketplace capabilities include a Merchant Portal, merchant/operator dashboards, offer/product management, automated order splitting, and approval workflows. spryker.com

That makes the architecture fairly natural:

Retailer → B2B buyer/account rules → product/price rules → vendor selection → vendor portal → order split → vendor fulfillment → tracking

For a dropship channel, that last part is particularly important: you don't just need a commerce storefront—you need somewhere suppliers can manage products, orders, inventory/fulfillment information and potentially payouts.

Spryker B2B Commerce

2. SAP Commerce Cloud — strongest enterprise alternative

If you're already an SAP shop, I'd take SAP Commerce very seriously. Its B2B model supports complex organizational structures, multiple supplier catalogs, inventory, contracts, customer information and orders. help.sap.com

More importantly for your use case, SAP's marketplace capabilities explicitly include vendor management, vendor product management, order management and vendor-user APIs. Vendor orders can be split from a master order, and vendors can approve/reject orders and provide fulfillment/tracking information. help.sap.com

That's very close to the operational model of enterprise dropshipping.

SAP Commerce Cloud

3. Adobe Commerce — excellent B2B engine, weaker native vendor story

Adobe Commerce has an excellent B2B foundation: company accounts and hierarchies, roles/permissions, shared catalogs, company-specific pricing, quotes, purchase orders and approval rules. experienceleague.adobe.com

So if your difficult problem is primarily "different corporate customers need different catalogs, prices, payment terms and approval workflows", Adobe is very compelling.

The distinction is that I'd treat the vendor portal/dropship marketplace as an architectural extension rather than assuming Adobe's native B2B functionality solves it. Its B2B model is fundamentally centered on your company selling to buyer companies. developer.adobe.com

Adobe Commerce B2B

4. Salesforce Commerce

Salesforce has a strong rules model around buyer groups, entitlements and price books, including buyer-specific pricing, product visibility and negotiated contract access. developer.adobe.comhelp.salesforce.com

I'd favor it when your enterprise already runs heavily on Salesforce—particularly if CRM, account management, sales processes and customer data need to be deeply integrated.

But for a supplier marketplace/dropship operating model, I'd rank Spryker/SAP ahead of it.

Salesforce Commerce

What I'd choose

If I were designing the RFP, my initial ranking would be:

1. Spryker — best single-platform conceptual fit for B2B + marketplace + dropship.
2. SAP Commerce Cloud — best if SAP/S4 is strategically important.
3. Adobe Commerce — best if B2B customer rules are the dominant complexity and vendor operations can be built/integrated.
4. Salesforce Commerce — rises considerably if Salesforce is already your enterprise backbone.
5. commercetools — compelling if your architecture team wants composability and is comfortable assembling more of the marketplace operating model.

The key RFP question I'd use isn't simply "Does it support dropshipping?" It's:

Can a vendor independently manage its assortment, inventory, orders, fulfillment SLAs and tracking while the retailer simultaneously enforces customer-specific B2B pricing, assortment, credit, approval, tax and shipping rules—and split a single customer order across multiple vendors?

That requirement will separate the genuinely suitable platforms from ordinary B2B ecommerce platforms very quickly.

For an enterprise retailer adding dropship while retaining complex B2B rules, I’d separate the decision into two layers: the commerce engine and the vendor/dropship operating layer. That distinction matters because vendor onboarding, catalog ingestion, fulfillment SLAs, commissions, and supplier self-service are not the same problem as B2B pricing and procurement.

My shortlist

1. Adobe Commerce — my pick if B2B rules are the hardest requirement

Adobe Commerce has unusually deep native B2B capabilities: company hierarchies, shared catalogs, customer-specific pricing, purchase orders, requisition lists, negotiable quotes and approval-oriented workflows. Recent independent comparisons continue to put it at the top for complex B2B requirements. elogic.co

The weakness is vendor/dropship management. Adobe gives you a highly extensible commerce core and an extension ecosystem, but a serious multi-vendor operation generally means adding a marketplace/dropship solution rather than getting the whole supplier operating model natively. Adobe explicitly supports extending Commerce through third-party apps/extensions. experienceleague.adobe.com

I'd choose it if: your B2B requirements include sophisticated account hierarchies, customer-specific assortments/pricing, RFQs, approvals, negotiated contracts, or unusual commercial rules.

2. VTEX — strongest single-platform candidate

VTEX is particularly interesting for your situation because it combines enterprise commerce with marketplace capabilities. Its B2B offering explicitly supports buyer portals, custom pricing, procurement integration and enforcement of commercial rules at checkout. www.vtex.com

That makes it more compelling than a conventional B2B platform if your strategy is:

Existing owned inventory + B2B customers + third-party assortment + dropship vendors + potentially a marketplace later.

I'd put VTEX through the RFP if you want to minimize the number of systems.

3. Mirakl — potentially the best answer for the vendor side

Mirakl is not what I'd use as the primary B2B commerce engine. I'd consider it the vendor/dropship layer sitting beside your commerce platform.

This is where it gets very compelling: Mirakl now explicitly supports both marketplace and dropship from the same platform, including vendor onboarding, catalog quality, vendor relationships, margin/commission management and operational workflows. www.mirakl.com Its Dropship product also handles vendor cost submissions, margin calculations and vendor-suggested pricing. www.mirakl.com

So an architecture such as:

Adobe Commerce / VTEX / existing commerce → Mirakl → vendors → customer

can be much cleaner than trying to turn the commerce platform itself into a supplier-management system.

4. commercetools — best if you're already a serious composable enterprise

commercetools makes sense if you have a strong engineering organization and want pricing, customer accounts, order orchestration, vendor services, PIM, OMS, etc. to be independently modeled.

The tradeoff is that you're buying architectural freedom rather than a finished B2B/vendor solution. Current comparisons characterize it as highly flexible but requiring substantially more custom development than Adobe or SaaS alternatives. elogic.co

I'd choose it if your architecture team is already committed to MACH/composable—not simply because it's technically elegant.

What I would not lead with

Shopify Plus is attractive if the primary objective is getting B2B + DTC live quickly. Its B2B capabilities have expanded substantially, but independent 2026 comparisons still identify gaps around things such as native RFQ/negotiated quotes and sophisticated approval/requisition workflows. elogic.co

For a retailer saying "complex B2B rules" rather than simply "we're adding wholesale customers," I'd be cautious about making Shopify the strategic foundation.

My recommendation

I'd take three architectures into an enterprise evaluation:

1. VTEX — best candidate for an integrated commerce + marketplace/dropship model.
2. Adobe Commerce + Mirakl — strongest candidate if sophisticated B2B rules are paramount and you're comfortable with a two-platform architecture.
3. commercetools + Mirakl — strongest candidate if your enterprise is committed to composable architecture.

The key RFP question I'd emphasize is not "does it have a vendor portal?" Instead, test the entire transaction:

Vendor onboarding → vendor-specific catalog → customer/account-specific price → B2B approval → order routing → vendor fulfillment SLA → split shipment → cancellation/return → vendor settlement → margin reporting.

A platform can demo a beautiful vendor portal and still fall apart when those rules interact.

If you tell me your ERP/OMS (SAP, Oracle, Manhattan, etc.), approximate SKU/vendor count, and whether you need marketplace commissions or purely dropship, I can narrow this to a 2–3 platform architecture and give you an enterprise-style scorecard.

For an enterprise retailer adding dropshipping, I’d shortlist Adobe Commerce, BigCommerce Enterprise, and a marketplace platform such as Mirakl—but the right choice depends heavily on whether your “vendor portal” means supplier self-service or a true third-party marketplace.

My recommendation

If dropshipping is becoming a major channel with dozens/hundreds of vendors, I'd look hardest at Adobe Commerce + Mirakl.

Adobe's B2B capabilities are unusually strong for an enterprise retailer: company hierarchies, buyer roles/permissions, shared catalogs with company-specific pricing, negotiated quotes, purchase-order approvals, payment/shipping rules, etc. experienceleague.adobe.com

Mirakl then handles the marketplace/supplier side—vendor onboarding, seller operations, catalog feeds, commissions, fulfillment workflows, etc. That separation is attractive because B2B customer rules and supplier rules are fundamentally different problems.

If you want fewer moving parts, BigCommerce Enterprise/B2B Edition is compelling. Its Buyer Portal supports company users, roles, quotes, invoices and account hierarchies; custom roles and permissions are also available through its APIs. docs.bigcommerce.com

The architecture I'd evaluate

Customer → Commerce platform → Order orchestration → Vendor portal → Supplier

Rather than trying to make the commerce platform itself do everything:

• Customer/B2B rules: account hierarchy, contract pricing, payment terms, approval thresholds, customer-specific assortment
• Commerce: cart, checkout, pricing, promotions
• Order orchestration: split orders, routing, inventory, SLA, returns
• Vendor portal: onboarding, SKU mapping, inventory, pricing, order acceptance, shipment/tracking, invoices
• ERP: financial system of record

The key architectural question I'd put in the RFP is:

Can a single customer order contain both first-party and dropship items, be split automatically by fulfillment source, and preserve customer-specific B2B pricing/terms while each vendor sees only its own order lines?

That's where superficially similar "B2B ecommerce" platforms start to diverge.

If you tell me roughly (1) number of vendors, (2) number of SKUs, (3) ERP—SAP/Oracle/etc., and (4) whether vendors need to manage their own catalog/pricing, I can give you a platform shortlist with a weighted scorecard for your use case.

For your use case, I’d shortlist Spryker, Adobe Commerce + Mirakl, and commercetools + Mirakl. The key distinction is whether you want the commerce platform itself to own vendor/dropship operations, or whether you want a dedicated marketplace/dropship layer.

My recommendation: Spryker

For an enterprise retailer adding dropshipping while retaining sophisticated B2B, Spryker is probably the cleanest fit.

Its B2B platform supports complex buying journeys, including CPQ/RFQ and customizable order-management workflows, while its Enterprise Marketplace functionality is explicitly designed for onboarding third-party merchants. spryker.com

Importantly, Spryker has a Merchant Portal where vendors can manage their profiles, offers, products and orders rather than forcing everything through your internal admin. docs.spryker.com

That combination matters because your requirements are really two problems:

Buyer side

• Account/company hierarchies
• Buyer roles and permissions
• Customer-specific catalogs
• Contract/customer pricing
• Approval workflows
• RFQ/negotiated pricing
• Credit/payment terms
• B2B-specific checkout rules

Vendor side

• Vendor onboarding
• Vendor-specific catalog/assortment
• Offer and price management
• Inventory feeds
• Order acceptance
• Fulfillment/shipping SLAs
• Returns
• Vendor performance
• Settlement/commission logic

Spryker is unusual in that those two sides are first-class parts of the same commerce/marketplace architecture.

The strongest alternative: Adobe Commerce + Mirakl

If you're already heavily invested in Adobe Commerce, I wouldn't necessarily replatform. Adobe's native B2B capabilities are very strong: company hierarchies, roles/permissions, shared catalogs, customer-specific pricing, negotiable quotes, purchase orders and approval rules are all supported. experienceleague.adobe.com

The weakness is the vendor portal/dropship side. I'd pair it with Mirakl rather than trying to turn Adobe into a marketplace platform through custom development.

Mirakl's Dropship product is specifically designed for enterprise dropship and can operate marketplace + dropship simultaneously. It also provides integrations with Adobe Commerce, Salesforce, SAP and other commerce/ERP systems. www.mirakl.com

So the architecture becomes:

Adobe Commerce → B2B customer experience, pricing, accounts, checkout
Mirakl → vendors, marketplace offers, dropship orchestration
ERP/OMS/PIM → enterprise systems of record

That's a very defensible architecture for a large retailer.

What I'd choose

If you're selecting a new commerce platform:

Spryker if you want the fewest major moving pieces and marketplace/dropship is strategically important.

If you're already an Adobe Commerce retailer:

Adobe Commerce + Mirakl is probably the lower-risk enterprise architecture.

If you're committed to composable/headless:

commercetools + Mirakl is worth serious consideration. commercetools provides the API-first, modular commerce foundation, while Mirakl handles the marketplace/dropship specialization. www.mirakl.comcommercetools.com

One important caveat: don't evaluate these primarily on storefront features. For your use case, I'd make the RFP heavily weighted toward rule-engine flexibility, vendor onboarding/portal capabilities, order routing, inventory ownership, split orders, returns, settlement, and ERP/OMS integration. Those are what will determine whether the dropship channel becomes an operational headache.

If you tell me your ERP/OMS/PIM stack (e.g. SAP, Oracle, Manhattan, Salesforce) and roughly number of vendors + SKUs, I can narrow this to a 2–3 platform recommendation and give you a weighted enterprise scorecard.

For an enterprise retailer adding dropshipping, I’d shortlist Spryker, VTEX, and Adobe Commerce + a marketplace layer such as Mirakl. The right choice depends on whether the vendor portal is core to the architecture or you mainly need sophisticated B2B buyer rules.

My recommendation: Spryker

For your specific combination—complex B2B rules + dropshipping + vendor portal—Spryker is probably the cleanest architectural fit.

Spryker explicitly positions its platform around B2B commerce, self-service portals, and enterprise marketplaces. Its marketplace capability includes merchant onboarding, catalog uploads, vendor permissions, offer management, and fulfillment tooling. spryker.com

That matters because your vendor model can become much more complicated than simply "seller lists a product." You may need:

• Vendor-specific assortment and pricing
• Customer/account-specific pricing
• Contract pricing
• B2B buyer hierarchies and approval limits
• Vendor SLAs and fulfillment rules
• Vendor-specific inventory feeds
• Drop-ship routing
• Split orders across first-party and third-party inventory
• Vendor commissions/fees
• Vendor onboarding and catalog approval
• Different shipping promises by vendor
• Returns/refund responsibility by vendor

Spryker also has B2B marketplace functionality specifically covering things such as merchant-specific prices, product approval, shopping lists, and quick ordering. docs.spryker.com

When I'd choose VTEX instead

VTEX is particularly attractive if you want a more integrated retail marketplace model rather than building a lot of the marketplace operating model yourself.

Its marketplace architecture supports external sellers, seller selection at checkout, trade policies, catalog mapping, payments, and a Seller Portal through which sellers can connect to the marketplace—even sellers that aren't running VTEX themselves. help.vtex.com

One particularly useful concept is the trade policy: it can control assortment, pricing, promotions, customer segmentation, payments, and shipping strategy for a sales channel. help.vtex.com

I'd put VTEX ahead of Spryker if your priority is getting an enterprise marketplace live relatively quickly with less custom marketplace infrastructure.

When I'd choose Adobe Commerce + Mirakl

This is compelling if your organization already has significant Adobe Commerce investment or if your B2B requirements are unusually deep.

Adobe Commerce's native B2B capabilities are strong: company hierarchies, buyer roles/permissions, shared catalogs, company-specific pricing, negotiable quotes, purchase orders/approval rules, requisition lists, and B2B-specific payment/shipping controls. experienceleague.adobe.com

Then Mirakl supplies the marketplace/vendor side. Mirakl is explicitly designed around enterprise third-party marketplaces, with seller onboarding, catalog management, seller operations, and integrations via API, CSV, XML, or EDI. www.mirakl.com

The downside is architectural complexity: you're operating a commerce platform + marketplace platform + integration layer, rather than getting the two domains from one platform.

The decision I'd make

If I were evaluating this for an enterprise retailer, my initial ranking would be:

1. Spryker — best overall fit
Especially if the retailer wants dropshipping to become a strategic marketplace/business model rather than just another fulfillment option.

2. VTEX — best packaged retail marketplace
Strong choice when speed, seller onboarding, omnichannel retail, and operational simplicity outweigh maximum architectural flexibility.

3. Adobe Commerce + Mirakl — best for sophisticated B2B + existing Adobe estate
Potentially the strongest choice if your B2B requirements are the hardest part and you already have Adobe Commerce expertise/investment.

4. Adobe Commerce alone — only if vendor marketplace requirements are modest
Its native B2B functionality is excellent, but I'd be reluctant to make it the sole foundation for a serious multi-vendor dropshipping operation.

One important distinction: don't evaluate these primarily on "does it have a vendor portal?" Evaluate where the rules execute. Your proof-of-concept should test a scenario like:

Customer belongs to B2B account A → buyer has spending limit B → sees contracted assortment C → gets customer-specific price D → product is supplied by vendor E → vendor has inventory F → order is split → vendor receives only its line items → vendor ships under SLA G → customer sees one consolidated order/tracking experience.

That scenario will expose the meaningful differences between these platforms much faster than a feature checklist.

If you give me your ERP/OMS, approximate SKU/vendor/customer counts, B2B complexity, and whether you already run Adobe/Salesforce/SAP/etc., I can narrow this to a 2–3 platform recommendation with a target architecture and integration map.

For an enterprise retailer adding dropshipping, the platform choice usually depends on whether you need (1) a sophisticated B2B commerce engine, (2) a true supplier/vendor operating portal, or (3) marketplace-style multi-vendor orchestration. Many retailers end up combining a commerce platform with a marketplace/dropship platform rather than forcing one system to do everything.

Here are the strongest fits:

For your use case, I’d shortlist:

1. VTEX + marketplace/dropship capabilities

• Best if you want your retail site to become a supplier ecosystem.
• Handles seller onboarding, marketplace operations, B2B buying flows, and complex commercial models. www.vtex.com

2. Adobe Commerce + Mirakl

• Best for a traditional enterprise retailer with:
  • complex promotions
  • customer-specific pricing
  • multiple brands/regions
  • heavy ERP/PIM/OMS integration
  • thousands of vendors
• Mirakl can handle supplier onboarding, vendor portals, catalog ingestion, and dropship workflows while Adobe remains the storefront/commerce engine. www.mirakl.com

3. commercetools + marketplace layer

• Best if your architecture team wants composable commerce:
  • ERP remains system of record
  • PIM manages catalog
  • OMS manages fulfillment
  • vendor platform manages suppliers
• Strong choice for very large retailers avoiding monolithic platforms. commercetools.com

Capabilities I would require in your evaluation

For enterprise dropship, don’t just check “does it support vendors?” Look for:

B2B rules

• Account hierarchies (parent company → divisions → buyers)
• Contract pricing
• Customer-specific catalogs
• Tiered pricing and rebates
• Quote workflows
• Approval chains
• PO workflows
• Credit limits/net terms
• Sales-rep assisted ordering

Vendor portal

• Supplier self-registration
• Vendor approval workflows
• Product submission
• Content enrichment
• Inventory feeds
• Price updates
• Purchase order acknowledgment
• ASN/shipping updates
• Returns handling
• Vendor performance dashboards

Operations

• Split shipments
• Multi-vendor carts
• Order routing rules
• SLA monitoring
• Commission/margin rules
• EDI/API connectivity
• Dropship inventory synchronization

A common enterprise architecture looks like:

Customer storefront
        |
Commerce platform
        |
OMS / Order orchestration
        |
-----------------------------
|             |             |
Owned DCs   3PLs       Dropship vendors
                         |
                  Vendor portal

If your retailer already has an ERP/PIM/OMS stack (SAP, Oracle, Manhattan, Salesforce, etc.), the answer changes significantly. The best platform is often the one that fits your existing order orchestration and catalog architecture rather than the one with the most storefront features.

For an enterprise retailer adding dropshipping while retaining complex B2B rules, I’d separate the decision into two layers: the commerce engine and the vendor/dropship management layer.

My shortlist

1. Adobe Commerce + Mirakl — my first choice

Adobe Commerce is particularly strong when your B2B model involves company hierarchies, negotiated pricing, customer-specific catalogs, purchasing permissions, quotes, POs, and complex rules. Adobe's B2B model explicitly supports companies with multiple users and purchasing permissions, shared catalogs, custom pricing, quotes, purchase-order workflows, and company hierarchies. experienceleague.adobe.com

Then put Mirakl alongside it for the supplier side. Mirakl Dropship is specifically designed for enterprise dropship operations, including vendor onboarding, catalog quality, and operational scaling. www.mirakl.com

Architecture:
Adobe Commerce → pricing/B2B/customer experience → Mirakl → vendors → fulfillment

That's a very natural fit if your "vendor portal" means vendors need to onboard, maintain SKUs/content, receive orders, acknowledge/fulfill them, manage inventory, and see operational performance.

2. BigCommerce B2B + Mirakl — potentially the sweet spot

I'd give BigCommerce B2B Edition serious consideration. Its native B2B capabilities are unusually good: company hierarchies, custom roles/permissions, quotes, invoices, approval workflows, purchase orders, and a buyer portal. docs.bigcommerce.com

It also supports up to five levels of company hierarchy and custom buyer roles, which is useful for enterprise customers with subsidiaries/franchises. docs.bigcommerce.comwww.salesforce.com

The important distinction is that BigCommerce's Buyer Portal is for your B2B customers, not a full supplier marketplace portal. I'd still pair it with Mirakl for the vendor side.

I'd choose this over Adobe if: you want strong B2B functionality but want a somewhat more SaaS-oriented implementation and don't need Adobe's level of extensibility/customization.

3. Salesforce Commerce — compelling if Salesforce is already your enterprise backbone

Salesforce Commerce is strong for contract pricing, catalogs, account hierarchies, roles and permissions, and B2B customer portals. Its Advanced edition also includes full Order Management. www.salesforce.com

I'd favor it when your retailer already has substantial investment in Salesforce CRM + OMS + Data Cloud, rather than selecting it purely for ecommerce.

Where I'd be cautious: Shopify Plus

Shopify has substantially improved its native B2B offering in 2026. Plus now supports unlimited B2B catalogs, company-specific catalogs, company locations, payment terms, quantity rules, and partial payments/deposits. help.shopify.com

It's therefore a legitimate enterprise B2B option—not the Shopify of a few years ago.

But for your particular combination of requirements, I'd put it behind Adobe/BigCommerce/Salesforce. The issue isn't whether Shopify can do B2B; it's whether you want to build your vendor/dropship operating model and unusual B2B rules around Shopify's ecosystem rather than starting with a platform designed for more complex commerce models.

What I'd recommend

If I were evaluating this for an enterprise retailer, my first POC would be:

1. Adobe Commerce + Mirakl
2. BigCommerce B2B + Mirakl
3. Salesforce Commerce + Mirakl
4. Shopify Plus + appropriate marketplace/dropship tooling

The key architectural decision is not to force the commerce platform to become the vendor-management platform. Let the commerce engine own customer/B2B pricing and checkout, while a marketplace/dropship layer owns supplier onboarding, assortment, vendor SLAs, inventory feeds, order routing, and vendor settlement.

If you tell me your ERP/OMS (e.g. SAP, Oracle, Manhattan), approximate SKU/vendor count, number of B2B customer accounts, and whether vendors need self-service onboarding + inventory/order management, I can narrow this to a 2-platform shortlist and lay out the target architecture.

For an enterprise retailer adding dropshipping while needing complex B2B rules and vendor portals, you’ll usually want a platform that can handle three separate operating models:

1. B2B commerce — account hierarchies, contract pricing, negotiated catalogs, approvals, PO workflows, credit terms
2. Dropship/vendor operations — supplier onboarding, vendor catalogs, inventory feeds, routing orders, SLAs, commissions
3. Enterprise integration — ERP/OMS/PIM/WMS connectivity, tax, fulfillment orchestration, analytics

The strongest candidates are:

My shortlist for your scenario

1. VTEX — if dropshipping/vendor marketplace is strategic

• Native marketplace model
• Seller onboarding
• Vendor catalogs
• Commission rules
• Multi-seller fulfillment patterns

www.vtex.com

2. Adobe Commerce + marketplace layer — if you are a complex retailer

• Best for unusual rules:
  • customer-specific pricing
  • regional catalogs
  • promotions
  • approval workflows
  • ERP-driven logic
• Large ecosystem of marketplace/vendor extensions

3. commercetools — if you want a long-term enterprise architecture

• Strong choice if you already have:
  • microservices/API strategy
  • internal engineering resources
  • multiple channels (store, app, marketplaces, B2B portals)
• Handles complex B2B structures such as business units, roles, and permissions. commercetools.com

Capabilities I would require in your RFP

Vendor portal

• Vendor self-registration and approval
• Vendor product upload/API ingestion
• Vendor inventory feeds
• Vendor order dashboard
• Shipment tracking updates
• Returns workflow
• Vendor SLA monitoring
• Commission/payment reconciliation

B2B rules

• Customer-specific catalogs
• Contract pricing
• Tier/volume pricing
• Account hierarchies (parent company → locations → buyers)
• Approval chains
• Quote/RFQ workflows
• Net payment terms
• Tax exemption handling
• Punchout/procurement integration if relevant

Dropship orchestration

• Split orders by supplier
• Route orders automatically
• Supplier inventory reservation
• Backorder rules
• Multi-node fulfillment visibility
• Exception management

A key architectural question: are you trying to become a marketplace (third-party sellers sell directly to your customers), or simply add supplier dropship capability (you remain merchant of record)?

Those two models often lead to different platform choices. For a retailer adding supplier dropship, I would generally favor Adobe Commerce, VTEX, or commercetools over a marketplace-first solution.

For your use case, I’d put VTEX at the top of the shortlist. The combination you described—enterprise retail + complex B2B commercial rules + adding dropship/third-party sellers + vendor self-service portals—is unusually well aligned with VTEX’s architecture.

My shortlist

Why I'd favor VTEX

VTEX has native marketplace functionality where third-party sellers can be onboarded, their catalogs integrated, offers managed, and orders routed to the appropriate seller. It explicitly supports external sellers that aren't already on VTEX. help.vtex.com

More importantly for your requirement, Seller Portal is an actual VTEX component, rather than something you'd have to build around the commerce platform. Sellers get capabilities around catalog, pricing, logistics and order management, and the portal can be customized through VTEX's Seller Portal Edition App. developers.vtex.com

VTEX also supports marketplace mechanics that matter for dropshipping: seller selection based on availability/location, split fulfillment, seller payouts/commissions, catalog integration and order orchestration. www.vtex.com

On the B2B side, VTEX positions its platform around buyer portals, custom pricing, procurement integration and enforcement of commercial rules at checkout. www.vtex.com

Where Adobe is stronger

If your dominant problem is very sophisticated B2B account structures, I'd seriously evaluate Adobe Commerce.

Its B2B capabilities are unusually mature: company hierarchies, multiple buyer roles/permissions, shared catalogs with company-specific pricing, negotiable quotes, purchase-order approval rules, requisition lists and company-specific payment/shipping rules. experienceleague.adobe.com

The tradeoff is that vendor marketplace/dropship is not as central to the product as it is in VTEX. You'd likely be assembling more of the seller-management experience through customization, extensions and/or a marketplace platform.

commercetools

commercetools is compelling if you have a strong internal engineering organization and want a composable architecture. Its B2B model supports arbitrary account hierarchies, granular roles, approval rules and sophisticated pricing/catalog models. commercetools.com

But for your particular requirement, I'd ask a critical question: do you want to build the vendor operating system, or buy it? VTEX gives you much more of the marketplace/seller workflow out of the box.

My recommendation

I'd frame the decision this way:

Choose VTEX if:

• Dropship/marketplace is a strategic growth channel, not just an experiment.
• You need hundreds/thousands of vendors eventually.
• Vendors need self-service onboarding and catalog/order management.
• You want seller selection, split orders, commissions and payouts integrated into the commerce stack.
• B2B and B2C need to coexist.

Choose Adobe Commerce if:

• Your B2B business rules are the primary complexity.
• Marketplace is relatively small or can be handled by a separate marketplace solution.
• You already have substantial Adobe Commerce investment/customization.

Choose commercetools if:

• Your architecture team strongly prefers composable.
• You're comfortable building the vendor portal, marketplace workflows and orchestration around APIs.

One caveat: don't evaluate this as simply "which platform has the best B2B features?" Your real architecture is probably B2B commerce + marketplace/seller management + PIM/catalog + OMS + vendor onboarding + payments/payouts. VTEX is particularly interesting because several of those pieces are designed to operate together rather than being stitched together.

If you give me your approximate GMV/SKU count, number of vendors (today and 3-year target), ERP (SAP/Oracle/etc.), and whether vendors need to set their own prices, I can narrow this to a VTEX vs Adobe vs commercetools architecture recommendation and call out the likely integration pain points.

For an enterprise retailer adding dropshipping while retaining complex B2B commerce, I’d shortlist Adobe Commerce, Spryker, VTEX, and commercetools—but they fit different operating models.

My recommendation

If your core problem is "we have complicated B2B pricing, accounts, approvals and purchasing rules, and now need to add dropship vendors," I'd start with Adobe Commerce.

Adobe's B2B stack natively handles company hierarchies, roles/permissions, company-specific catalogs and pricing, negotiable quotes, purchase-order approval rules, credit, requisition lists, and differentiated payment/shipping rules. experienceleague.adobe.com

That matters because you don't want the vendor/dropship initiative to force you to replace or weaken your existing B2B model.

Adobe Commerce B2B documentation

But there's an important distinction: a vendor portal is not the same thing as a B2B buyer portal. If your dropship suppliers need to independently log in, manage products, inventory, fulfillment SLAs, orders, returns, commissions, and payouts, I'd put Spryker and VTEX alongside Adobe in the RFP. Marketplace capabilities are much more central to their architectures; independent comparisons also identify Spryker and VTEX specifically for marketplace models. www.shopify.com

How I'd decide

• B2B rules are #1; vendors are an additional channel → Adobe Commerce
• Marketplace/vendor ecosystem is becoming a major business model → Spryker
• Want marketplace + commerce functionality with less custom assembly → VTEX
• Have a substantial engineering team and want composable control → commercetools; its B2B offering supports account hierarchies, granular permissions, approval rules and complex pricing, but the architectural freedom comes with more implementation responsibility. commercetools.com
• Already deeply invested in Salesforce → Salesforce Commerce Cloud; its B2B offering is particularly attractive when commerce needs to sit tightly within the Salesforce ecosystem. www.salesforce.com

One architectural point I'd insist on in your evaluation: don't make the commerce platform the system of record for vendor operations. I'd separate B2B customer/pricing rules, vendor onboarding/catalog, inventory/availability, order routing, fulfillment, and settlement/commission into explicit domains. That will matter enormously once you have hundreds or thousands of dropship vendors.

If you tell me roughly (1) number of vendors, (2) whether vendors need a self-service portal, (3) ERP/OMS you use, and (4) how complicated your B2B pricing/approval rules are, I can narrow this to a 2–3 platform shortlist and an enterprise RFP scorecard.
