Magento B2B: Open Source vs Adobe Commerce

Magento B2B features depend on the edition. The B2B module ships only with Adobe Commerce: company accounts, shared catalogs, negotiable quotes, purchase order approvals, requisition lists and quick order. Magento Open Source has none of them built in. It still covers customer groups, group and tier prices, minimum order quantities and offline payment methods, and many wholesale stores need nothing more.

For a B2B store, the bigger job is usually the integration. Customer prices, credit limits and stock per warehouse live in the ERP, and the store has to show the same numbers.

What the Adobe Commerce B2B module adds

Adobe ships B2B as the magento/extension-b2b extension, which installs on Adobe Commerce only. Its main features, from Adobe’s B2B introduction:

• Company accounts. Several buyers from one company share an account. The company admin builds divisions and users, and gives each role its own permissions for ordering, quoting and credit.
• Company credit. Companies can pay on account against a credit line that the merchant sets.
• Shared catalogs. Custom prices per product for different companies. Shared catalogs need company accounts.
• Negotiable quotes. A buyer requests a quote from the cart, or a seller starts one in the admin. Both sides change items, quantities and discounts until they agree.
• Purchase order approvals. Orders become purchase orders that go through approval rules set per company role.
• Requisition lists. Saved lists of products a buyer orders often, added to the cart in one step.
• Quick order. Logged-in buyers add products by SKU or name without browsing the catalog.

Every feature in this list depends on the Adobe Commerce licence.

What Magento Open Source already covers

Magento Open Source has the building blocks of a wholesale store in its core code:

• Customer groups. Put wholesale buyers in their own group, apart from retail customers. Prices, tax classes and catalog price rules follow the group.
• Group prices. Set a separate price per product for each customer group.
• Tier prices. Lower the unit price from a set quantity, for one group or for all. With tiers at 24 and 48 units, a cart of 30 units gets the 24-unit price.
• Minimum and maximum order quantities. Set the smallest quantity a customer can add to the cart per customer group, and a maximum for everyone.
• Offline payment methods. Purchase order, check or money order, bank transfer and cash on delivery all come with the core OfflinePayments module.

A distributor with one price list per group, quantity discounts and payment by bank transfer runs on Open Source as it is.

Closing the gap on Open Source

Some stores need one or two B2B features without the rest. There are two routes:

• Extensions. Third-party extensions add features such as request-a-quote or quick order to Open Source. Pick focused modules and test them together on staging, because extensions that each change the cart and checkout can conflict.
• Custom work. A request-a-quote form tied to your sales process is often a small module. So is quick order against your own SKU rules. Custom work fits your workflow and adds only the code you use.

Compare the total with the Adobe Commerce licence before you commit. Three or four B2B extensions plus the work to keep them compatible on every upgrade adds up. When you need most of the B2B module, the licence can cost less than rebuilding it piece by piece.

The integration side of Magento B2B

B2B buyers expect the prices, credit and stock their account manager quotes them. That data lives in the ERP, so a Magento 2 B2B store is only as good as its ERP integration:

• Customer-specific prices. The ERP holds price lists and contract prices per customer. The integration maps them to customer groups, group prices or shared catalogs.
• Credit limits. The ERP owns the credit line. The integration pushes the limit and open balance to the store, so buyers see what they can spend.
• Stock per warehouse. Inventory sources in Magento follow the ERP’s warehouse stock, so buyers see real availability per location.
• Orders back to the ERP. Orders, including purchase order numbers, flow to the ERP for fulfilment and invoicing.

Magento B2B compared with Shopify

Shopify Plus includes B2B with unlimited catalogs. Since 2026, the lower Shopify plans also include basic B2B with up to 3 catalogs (Shopify Help Center). For a store with a few wholesale price lists and standard products, that can be enough.

Magento fits when B2B depends on ERP-driven prices per customer, complex products or approval flows that apps can’t express. Our Magento vs Shopify comparison covers the wider trade-off.

Where to start

List the B2B features your buyers use today, and mark the ones Open Source already covers. If the gaps are one or two features, extensions or custom work close them. If you need most of the B2B module, price the Adobe Commerce licence against the rebuild. In both cases, plan the ERP integration first, because it decides what buyers see.
