The Magento 2 B2B module is available both as part of Adobe Commerce (Enterprise Edition) and as a standalone open-source B2B extension. The core B2B features — company accounts, shared catalogues, negotiable quotes, and purchase orders — are enabled and configured via Stores → Configuration → B2B Features. Each feature can be toggled independently, allowing you to enable only the capabilities your trade portal requires.

Magento 2 B2B module — six core features and their configuration dependencies

Magento 2 B2B Module: Enable Features in the Correct Order

The Magento 2 B2B module features have dependencies. Enable them in this order to avoid configuration conflicts:

Magento 2 B2B Module: Company Account Structure

Company accounts in the Magento 2 B2B module support a three-tier hierarchy: the company account itself, company administrators (who manage the account, users, and purchasing rules), and company users (buyers within the organisation). This hierarchy allows large trade accounts to self-manage their own users, payment methods, and purchasing approval chains without contacting your store admin.

• Company Admin: manages users, teams, roles, and credit limits. Can submit and approve quotes. Full control over company purchasing settings.
• Default User: can browse, add to cart, and submit orders up to any purchase order approval limits the admin has set.
• Custom Roles: create as many roles as needed with granular permissions — view quotes but not submit, view purchase orders but not approve, view invoices only.

Magento 2 B2B Module: Shared Catalogue Configuration

A shared catalogue in the Magento 2 B2B module is a curated product set with custom pricing assigned to specific company accounts. One company sees pricing tier A, another sees tier B, and retail visitors see the standard catalogue. Configure shared catalogues from Catalog → Shared Catalogs.

<?php
use MagentoSharedCatalogApiSharedCatalogManagementInterface;
use MagentoCompanyApiCompanyRepositoryInterface;
use MagentoSharedCatalogApiCompanyManagementInterface;

class AssignCatalogToCompany
{
    public function __construct(
        private readonly CompanyRepositoryInterface         $companyRepo,
        private readonly SharedCatalogManagementInterface  $catalogMgmt,
        private readonly CompanyManagementInterface        $companyCatalogMgmt
    ) {}

    /**
     * Assign a shared catalogue to a company in the Magento 2 B2B module.
     */
    public function assign( int $companyId, int $sharedCatalogId ): void
    {
        $company = $this->companyRepo->get( $companyId );
        $catalog = $this->catalogMgmt->getPublicCatalog(); // or load by ID

        // Assign the company to the shared catalogue
        $this->companyCatalogMgmt->assignCompaniesToCatalog(
            $catalog,
            [ $company ]
        );
    }
}

Magento 2 B2B Module: Negotiable Quotes Setup

Negotiable quotes allow trade buyers to submit a cart for price negotiation, reducing the need for phone calls and email chains. The sales rep sees the submitted quote in the admin, can adjust line prices or add a shipping proposal, and the buyer accepts or counters. Enable negotiable quotes in B2B Features and configure default expiry and minimum order value in Stores → Configuration → Sales → Quotes.

Magento 2 B2B Module: Purchase Order Approval Rules

Purchase order approval rules in the Magento 2 B2B module allow company administrators to require management approval for orders above a certain value. Configure approval rules per company from the Company Admin portal or programmatically via the PurchaseOrderApprovalRuleRepositoryInterface API.

The Adobe Commerce B2B module documentation covers the complete feature set and configuration reference. The Magento 2 B2B module developer documentation covers the API interfaces for programmatic company and catalogue management.
