B2B Ecommerce Platform Comparison 2026: Which Fits Your Stack

A B2B ecommerce platform comparison comes down to three data-model questions: how each platform represents a buying company and its people, how it attaches negotiated prices to them, and how a quote becomes an order. Feature checklists blur those differences; the object models do not. This guide compares Shopify Plus, BigCommerce B2B Edition, Adobe Commerce, Salesforce B2B Commerce, commercetools and OroCommerce on exactly those three questions, using each vendor's own documentation, and closes with the five checks we run before recommending one.

Every platform fact below links to the vendor page it comes from. Where we give a view, we say so. Build costs are not in the tables because they depend on your ERP and catalogue; our ecommerce development services page explains how we scope them.

The six B2B platforms at a glance

How each platform models the buying company

The company model decides how easily your storefront reflects commercial reality: regional subsidiaries, branch offices with their own delivery addresses, and the procurement officers allowed to approve an order. If the platform cannot model distinct locations under one shared agreement, you will end up patching account logic with middleware.

Shopify Plus. Shopify B2B structures trade accounts around companies, company contacts and company locations, with catalogs attached to locations so that one buyer can hold different prices and terms per branch. Our reading of the model: locations sit under the company as a list rather than a multi-level tree, which is enough for most wholesale books and not enough for a group with divisions inside divisions. The features are available on Basic, Grow, Advanced and Plus, with the deeper set on Plus; our Shopify B2B guide walks through the plan split.

BigCommerce B2B Edition. The B2B Edition APIs expose Companies with sub-resources for configuring account hierarchy and managing Company user roles and permissions, plus addresses, payments (payment methods, available credit and net terms), invoices, orders and quotes. The GraphQL Storefront API covers the Buyer Portal use cases, including adding Company users, taking sales quotes to checkout, approving Shopping Lists and starting or ending Super Admin Masquerade, which is how a sales representative acts on a buyer's behalf. Our B2B Edition pricing and architecture post covers the plan side.

Adobe Commerce. Companies are the buying entity, and pricing reaches them through shared catalogs: a shared catalog must be assigned to one or more companies before company users can see it.

Salesforce B2B Commerce. Buyers live inside Salesforce, so the hierarchy is the CRM's; the public pricing page publishes edition limits rather than a data model. Salesforce's B2B editions include 6 shop fronts on Growth and 10 on Advanced, 20 inventory locations on both, and Order Management Lite or Full; licence prices are contact-for-pricing.

commercetools. Business Units represent Companies or Divisions and can be organised hierarchically up to a maximum of 5 levels (a soft limit that commercetools says can be raised per project after a performance review). Divisions can inherit Stores, Associates and their roles, and Approval Rules from parent units, and buyers are Associates, that is Customers holding Associate Roles, so one person can hold different roles in different divisions.

OroCommerce. Oro models the structure through customers with a parent customer: subsidiaries and divisions appear under the parent, and a price list can be configured per customer.

Our view: the platform you want is the one whose model can describe your top twenty accounts without invented metadata. If an account only fits once you add a custom table to track who may approve what, that platform is a mismatch for your business, however good the storefront looks.

Contract pricing under ERP load

Contract pricing has to resolve tiered price breaks, customer-specific overrides and currency rules without slowing the storefront or exhausting API limits during a nightly ERP sync. The question is where the prices live.

Shopify keeps negotiated prices in catalogs and price lists assigned to company locations, with variant minimums, maximums and increments set through the quantityRulesAdd mutation on a price list. BigCommerce B2B Edition exposes Company payment methods, available credit and net terms through its APIs, and negotiated pricing attaches through core BigCommerce price lists. Adobe Commerce isolates distribution through shared catalogs assigned to companies. commercetools leaves pricing to you: the API gives you the objects, and your pricing logic, or your ERP, supplies the numbers. OroCommerce configures a price list per customer in the back office.

Our view from integration work: platforms that keep contract prices separate from the base product record cope better with high-frequency syncs, because a price update does not invalidate the product document and its caches. Whichever platform you choose, measure your daily price and stock revision volume against its published API rate limits before you sign; our Shopify rate limits guide shows what that calculation looks like on one platform.

Quotes and approvals

A procurement manager rarely buys capital equipment through a card checkout. They expect to submit a list, request terms and wait for internal sign-off. Adobe Commerce's NegotiableQuote module lets a company user and a seller negotiate product and shipping prices before the order is placed. BigCommerce B2B Edition creates and processes sales quotes through its APIs and takes them to checkout from the Buyer Portal. Shopify handles the equivalent through draft orders with payment terms, which a representative sends as an invoice to an authenticated checkout. commercetools has Quote Requests, Quotes and Approval Rules as first-class objects that Business Units can inherit. OroCommerce handles requests for quote and quotes through its storefront and back office.

B2B ecommerce platform for manufacturers: custom assemblies

Build-to-order manufacturing introduces dynamic bills of materials, technical attachments and part configurations that strain a conventional catalogue schema. Shopify's variant structure has documented limits per product, covered in our variant limits guide, and configured products often end up as line-item properties plus a custom app rather than as variants. In our view Adobe Commerce handles custom attribute combinations natively, at the cost of indexing time on large catalogues. When a manufacturer needs genuine configure-price-quote behaviour, a SaaS platform needs a companion service, and a composable stack lets you keep the product projection in commercetools while your ERP calculates the price.

B2B ecommerce platform for distributors: dense catalogues and punchout

Trade distributors serve contractors who arrive with a list of fifty part numbers and need a fast bulk order form, live stock across warehouses, and increasingly punchout into their procurement system over cXML or OCI. Shopify's quick order list and B2B Edition's Shopping Lists cover the first; inventory locations and the APIs cover the second; in our view punchout is the area to check hardest on the SaaS platforms, where it typically arrives through connector apps. Confirm the punchout requirement with your largest accounts before you shortlist, because it moves the answer.

How to choose a B2B ecommerce platform in five steps

1. Audit your ERP contract data model. Document how customer hierarchies, negotiated price breaks and credit terms are structured today. The right platform ingests that shape without a translation layer per transaction.
2. Map the procurement hierarchy of your top twenty accounts. Establish whether buyers need departmental approvals or simple location-based ordering, then test each account against the company model above.
3. Benchmark catalogue update throughput. Count daily price and stock revisions at peak and compare the payload against the platform's published API limits.
4. Check the checkout boundaries. Split deliveries, purchase order uploads and net terms must be possible inside the platform checkout, not through a redirect.
5. Model five-year cost from published sources. Shopify publishes Plus pricing; BigCommerce lists its plans (see our 2026 pricing update); Adobe, Salesforce and commercetools quote per contract. Add hosting, connectors and the engineering retainer, and compare like with like.

Where to start this week

Extract sample payloads from your ERP for five trade accounts: the simplest single-location wholesaler, the most complex multi-division group, and three with bespoke price lists and quantity breaks. Map each against the native account schema of your shortlisted platforms. If an account forces you to invent custom metadata just to record who can approve an order, that platform is an architectural mismatch. Then review how your sales team negotiates quotes today, because the quoting model that matches their habit is the one they will use.

If you are planning a B2B replatform and want your ERP contracts modelled against the native platform APIs before you commit, our ecommerce development team runs that discovery; for the two SaaS options side by side, see BigCommerce B2B Edition and the Shopify B2B guide.
