B2B ecommerce: complete guide

How to design and build a B2B online store that handles the real complexity of business-to-business sales

10 min

B2B ecommerce is growing faster than B2C, but its requirements are radically different. Volume-based pricing, order approvals, customer-specific catalogs, ERP integration and complex sales cycles mean platforms designed for end consumers fall short.

This guide examines the specific challenges of B2B ecommerce, the must-have features, key differences from the B2C model, and how to design self-service portals that your corporate customers will actually want to use.

Fundamental differences from B2C

While B2C purchases are individual, often emotional and generally lower-ticket, B2B involves multiple decision-makers, recurring orders, negotiated pricing and significantly higher average order values.

These differences shape the entire store architecture: from catalog structure to checkout flow, payment methods and integration with the buyer’s internal systems.

  • Committee buying: multiple roles (buyer, approver, admin) with different permissions
  • Negotiated pricing: customer-specific, volume-based, contract or group rates
  • Recurring orders: quick reorder, saved purchase lists, subscriptions
  • Complex invoicing: net-30/60/90 payment terms, credit lines, partial orders
  • Personalised catalogs: each customer sees only their authorised products and prices

Pricing and rate management

Pricing management in B2B is one of the greatest technical challenges. A single product can have dozens of different prices depending on the customer, volume, framework contract, currency and negotiated terms.

The platform must support multiple price lists, volume-based discounts (tier pricing), prices hidden until login, contract rates linked to the CRM, and request-for-quote workflows for special orders. Without this flexibility, the sales team ends up processing orders by email or phone, defeating the purpose of the ecommerce platform.

B2B catalog management

B2B catalogs tend to be more complex than B2C: products with multiple technical variants, product relationships (compatibility, mandatory accessories), different sales units (unit, box, pallet) and associated technical documentation (data sheets, certifications, manuals).

A PIM (Product Information Management) tool like Akeneo, Salsify or Pimcore becomes almost essential when the catalog exceeds 500–1,000 references with complex data. The PIM acts as a single source of truth and feeds both the ecommerce store and offline channels (printed catalogs, sales rep sheets).

ERP, CRM and logistics integrations

In B2B, the ecommerce platform is not a standalone system: it must integrate bidirectionally with the ERP (stock, pricing, orders, invoicing), the CRM (customers, opportunities, contracts) and logistics systems (warehouse, transport, tracking).

The most critical integrations are real-time inventory synchronisation (to prevent selling out-of-stock products), automatic order transfer to the ERP, and shipping status updates in the customer portal. Well-designed REST APIs, middleware like Celigo or MuleSoft, and webhooks enable robust integrations.

  • ERP: SAP, Microsoft Dynamics, Odoo, NetSuite — stock, pricing and order sync
  • CRM: Salesforce, HubSpot, Pipedrive — customer data, contracts, segmentation
  • Logistics: WMS and carrier integration for real-time tracking

Self-service portals

The self-service portal is the feature that delivers the most value to B2B buyers. It lets customers check order status, download invoices, reorder regular products, manage account users and track shipments without contacting the sales team.

A well-built B2B portal reduces sales team enquiries by 30–50%, frees commercial staff for strategic accounts and improves customer satisfaction by granting autonomy. Key features include: order history with advanced filters, one-click reorder, PDF invoice download, multiple shipping address management and online quote requests.

Platforms built for B2B

Not all ecommerce platforms are B2B-ready. Generic options like Shopify or WooCommerce can work for simple B2B, but show serious limitations with complex pricing, multi-role approvals and personalised catalogs.

  • OroCommerce: built exclusively for B2B with approval workflows, multi-tier pricing and integrated CRM
  • Adobe Commerce (Magento): native B2B modules (company accounts, shared catalogs, negotiable quotes)
  • Shopify Plus: native B2B since 2023 with per-company price lists, dedicated checkout and B2B+B2C blending
  • Saleor / Medusa: open-source headless platforms that allow custom B2B flows
  • BigCommerce B2B Edition: price lists, order approvals, per-company portals

Key Takeaways

  • B2B requires features that B2C platforms lack: per-customer pricing, approvals, personalised catalogs
  • Complex pricing management is the biggest technical challenge in B2B ecommerce
  • A PIM is nearly essential for catalogs with 500+ complex references
  • Bidirectional ERP and CRM integration is mandatory for efficient operations
  • Self-service portals reduce sales enquiries and improve the customer experience
