What is the best B2B ecommerce platform in 2026?

Salesforce B2B Commerce tops the score because it covers the most ground for a structured B2B operation. The Growth edition gives you 6 storefronts and 20 inventory locations, with Order Management Lite. Advanced goes to 10 storefronts and adds full Order Management (the OMS that decides where each order ships from). The real payoff is on the sales side: your rep sees in the CRM what the account ordered online, and the buyer finds online the terms their rep negotiated.

You won't find a price. Both editions say "Contact for pricing". Salesforce at least states its model: a percentage of GMV, counted only on storefront revenue, minus tax and shipping. A phone order keyed into the ERP stays out of that number, but tracking it in Salesforce means buying standalone Salesforce Order Management, which covers orders from other channels.

The catch is the project. You need Salesforce-certified developers or a partner, and the platform only makes sense if Salesforce is already your CRM. Otherwise you pay a premium for an integration Shopify Plus or OroCommerce gives you for less.

Shopify Plus is one of the few platforms here that shows its price without a sales call: $2,500 a month on a one-year term, $2,300 on three years. For B2B it adds what lower plans lack: unlimited catalogs, catalogs assigned directly to a company or one of its locations, deposits, partial payments and payment requests per fulfillment.

The 2026 change matters. Basic, Grow and Advanced now include native B2B too: company accounts, quantity price breaks, net terms, PO numbers, quick order lists, plus ACH and vaulted cards in the US. The limit is 3 active catalog assignments, and a catalog assigned to two markets counts twice. Three price lists (dealers, distributors, key accounts) fit. If every big account has its own prices, you need Plus.

Two things to know. The variable fee exists, with different rules for B2B and DTC, and Shopify publishes neither the rate nor the threshold. And merchants who moved from the old Wholesale channel to native B2B found that order minimums were gone and had to pay a developer to rebuild them.

OroCommerce is, with Sana, one of the two platforms in this ranking designed for B2B first, and the richer of the two on the buying journey. Customer accounts have hierarchies (HQ, subsidiaries, buyers), price lists attach to an account or a group, and quotes are part of the core flow, not a bolted-on app.

There are two editions. Community is free and open source: you host it, you maintain it. Enterprise, where most of the advanced B2B features live, is quoted on your GMV, starting with 25 admin users, with hosting billed separately (OroCloud, private cloud or on-premise).

The price of that power is the project. Oro runs on Symfony, and user reviews describe a steep learning curve for theming and customization. One Gartner reviewer sums it up: "Solid, well-supported, highly-customizable B2B eCommerce software, but lacking a robust user community". Post-launch support gets good marks. Budget for a specialist partner, not a Shopify agency.

BigCommerce is the other big B2B SaaS, and on paper its B2B Edition goes further than Shopify's native B2B. It includes a CPQ quote engine that buyers start from a product page or cart, company hierarchies with roles, credit limits, purchase orders, net terms and pricing by parent company, subsidiary or buyer. Your rep can also place orders on a buyer's behalf.

On price, BigCommerce publishes its Performance plan from $1,499 a month billed annually, for merchants above $1M in sales, with B2B price lists included. The B2B Edition itself has no public price and no named plan on the official page: ask whether it's included or billed on top.

Two watch-outs. The new Buyer Portal doesn't support legacy B2B themes, and a custom theme means development work. And some merchants describe support as slow and scripted. Line up a partner agency for technical issues.

Sana Commerce starts from one idea: the store doesn't copy the ERP, it reads it. Net prices, stock and each account's terms come from the ERP when the buyer looks at them. That avoids the classic failure where the store shows a stale price because an overnight sync broke.

The flip side is ERP choice. Sana only connects to Microsoft Dynamics (Business Central, Finance & Supply Chain, AX, NAV) and SAP (ECC, S/4HANA, Business One). On NetSuite, Epicor, Acumatica or Sage, look elsewhere.

No price is published. A competing vendor also flags points to check in a demo: some B2B rules are configured in Sana rather than in the ERP, so you maintain them in two places. Ask to see your own discount matrix running on your own data.

Adobe Commerce (formerly Magento Commerce) ships the most complete native B2B module. Company accounts with roles, shared catalogs that set what each customer sees and pays, requisition lists for reorders, negotiable quotes, purchase orders with approval rules and quick order by SKU. Turning on company accounts enables shared catalogs and quotes by default.

All that comes at a cost. Adobe publishes no price, and the module doesn't exist on Magento Open Source, the free version. You need a specialist agency, and upgrades add up: versions 2.4.4 and 2.4.5 stop getting security patches after 2027, 2.4.6 after 2028.

If you're already on Magento, it's the shortest path to rich B2B. Starting from scratch, compare the three-year cost against OroCommerce, which covers the same needs.

Shopware, a German vendor, publishes its pricing and says plainly which B2B features sit in which edition. That's rare. Evolve, from €2,400 a month, brings roles and permissions, quotes and purchase approvals, quick order, shopping lists, budgets, org units and a sales agent mode to act on a customer's account. Rise and Community have none of these.

The catch is one line down. Individual pricing (percentage, fixed or tiered discounts) is in Evolve, but customer-specific prices imported from your ERP are Beyond-only, by quote. For a distributor whose prices live in the ERP, Beyond is the edition to price.

On the ground, listed prices are entry points that rise with GMV. Merchants on the official forum call the pricing "undurchsichtig" (opaque) and report a lower GMV cap in year two of a negotiated deal.

Sylius is an open source ecommerce framework on Symfony, built in Poland. The standard edition is free under the MIT license. Sylius Plus starts at €800 a year, then pricing follows your GMV band and the modules you add. For B2B, the B2B Suite module brings organization accounts, price lists per organization or group, category discounts and tiered pricing.

On paper, it's the lowest license in this ranking. In practice, everything rides on your partner: ERP connector, theme, maintenance. Development is the real cost.

The limit mirrors OroCommerce, only stronger: fewer features out of the box and a smaller ecosystem than Shopify or Magento. Pick Sylius to control your code, not to move fast.
