Best B2B Ecommerce Platform UK: 5 Options Compared

The best B2B ecommerce platform for a UK business is the one that supports its trade pricing, purchasing rules and back-office systems at an affordable total cost. Use Shopify and WooCommerce as starting points for a hosted store or an existing WordPress site. Compare BigCommerce B2B Edition, Adobe Commerce B2B and OroCommerce when your shortlist needs more involved purchasing workflows.

Reviewed 12 September 2026. This is a comparison of public vendor documentation, with links beside the relevant claims. The shortlisting guidance is an interpretation of those features, not a hands-on benchmark or a report of client results. Confirm the exact edition, configuration and contract in a demo and written proposal.

Best B2B Ecommerce Platforms Compared for UK Businesses

Start with the workflow you need to prove. The table gives each option a reason to be on your shortlist and a question that could rule it out. Detailed sources and plan qualifications follow below.

Already have a shortlist? Go straight to the UK requirements checklist, cost comparison or integration demo checks. If you need a team to turn those requirements into a store, see our Shopify, WooCommerce and bespoke ecommerce development service.

Shopify: Check the B2B Plan Limits

Shopify now documents B2B on Basic, Grow, Advanced and Plus, including company accounts and net terms. Basic, Grow and Advanced allow three active B2B market catalogue assignments in total and require new Shopify Markets for those catalogues. Plus supports unlimited market catalogues and direct assignment to companies or locations. Deposits and partial payments are also Plus-only. See Shopify's B2B features by plan.

Demo question: can your negotiated prices be represented by shared trade groups, or does each customer need its own catalogue? Bring representative price lists so the supplier can demonstrate the required plan. Test your approval and quoting steps too, including any proposed apps.

BigCommerce: Assess the Whole B2B Edition

BigCommerce's B2B Edition documentation describes company accounts, sales-representative quoting, shared shopping lists, purchase-order payment options and an invoice portal. These are B2B Edition capabilities; do not assume a general retail subscription includes the same scope. See BigCommerce's B2B Edition overview.

Demo question: can a buyer request a quote, accept revised terms and find the resulting invoice without your staff re-entering information? Ask for the B2B package, storefront work, connectors and support to be itemised in the proposal.

Adobe Commerce: Allow for the B2B Extension

Adobe documents B2B through an installed and enabled extension. It supports company structures and permissions, shared catalogues, negotiable quotes, purchase-order approvals and company credit. Several features depend on company accounts being configured. See Adobe's introduction to Commerce B2B.

Demo question: can the proposed configuration reproduce your divisions, buyer roles and approval thresholds? Have the implementation partner identify extension versions, upgrade responsibilities and any custom work. The feature list alone does not establish the cost or delivery time for your store.

WooCommerce: Evaluate the Extension as Well as the Store

For WordPress-based selling, assess a specific B2B extension alongside WooCommerce. For example, the B2B and Wholesale Suite listing describes group pricing, quote requests, bulk ordering and multi-user accounts. Those are features of the extension, not evidence that every WooCommerce installation includes them.

Demo question: does the chosen extension work with your theme, checkout, payment provider and accounting connector? Agree who handles backups, security updates and compatibility testing. Test representative catalogue sizes and concurrent orders; this guide has not benchmarked platform capacity.

OroCommerce: Scope Workflows and Integrations

OroCommerce lists account hierarchies, account-specific catalogues, a built-in CRM and configurable sales and approval workflows. See its official feature list. Its pricing explanation describes licence factors including commerce volume and internal users, with hosting dependent on deployment. It also distinguishes integration tools from integration work performed by your team or partner.

Demo question: which of your workflows can be configured in the quoted package, and which need development? Name the team responsible for connecting your ERP and maintaining that connection after upgrades.

What to Look for in a B2B Ecommerce Platform (UK Checklist)

Write a short requirements sheet before requesting demos. Use actual order examples with customer details removed.

• Prices and catalogues: list price, account price, volume breaks, pack sizes and which products each buyer may see.
• Company purchasing: who can order, who approves, whether branches share an account and how spending limits work.
• Quotes and payments: when a quote becomes an order, how purchase-order numbers are captured and who authorises credit.
• UK operations: GBP pricing, delivery areas, postcode restrictions, invoice details and the VAT scenarios your accountant needs to confirm.
• Systems: the exact Sage, Xero, QuickBooks, ERP or warehouse product and version, plus which system owns each record.
• Buyer experience: reorder a previous basket, find a known SKU, download an invoice and use the store on a phone.

Separate launch requirements from later improvements. A distributor selling sealed cases may need pack increments before personalised recommendations. A supplier with individually negotiated contracts may need account pricing before a redesigned storefront.

B2B Ecommerce Platform Decision Framework: Which Suits Your Business?

Shortlist by purchasing complexity and your team's ability to operate the system. Annual turnover alone does not tell you whether a platform fits.

Consider these illustrative requirements:

• A wholesaler with a few shared trade price lists should first prove registration, catalogue access and reordering on a simple setup.
• A distributor giving every customer different contract prices should test price maintenance, account isolation and synchronisation with its ERP.
• A manufacturer with quote-led orders should test negotiation, approval, deposits where needed and fulfilment changes before choosing a storefront.

If the same requirement needs substantial custom work across every shortlisted platform, compare that work with a bespoke ecommerce implementation. Include the ongoing responsibility for security, support and upgrades in that comparison.

How Much Does a B2B Ecommerce Platform Cost?

Ask suppliers to price the same scope over three years. Record billing currency, VAT treatment, renewal terms and usage limits alongside each figure. Do not compare a basic retail subscription with a complete enterprise implementation.

There is no like-for-like UK implementation price verified in this guide. Obtain current quotes for your requirements rather than treating an advertised entry price as a project budget.

Integration: What to Prove Before Signing

Map each record's owner and direction of travel. For example, your warehouse system might own available stock while your accounting system owns invoice numbers. Agree the expected delay between a change in one system and its appearance in another.

Ask the supplier to demonstrate these cases:

1. An approved trade order: the correct account price reaches the order, invoice and warehouse without being retyped.
2. A changed order: a partial shipment, cancellation or refund leaves both systems consistent.
3. A failed sync: the team can identify the missing record and retry without creating a duplicate order or invoice.
4. An account restriction: a buyer cannot see another company's prices, orders or credit information.
5. An accounting check: your finance team can reconcile the transaction and confirm the required tax and reporting workflow.

Getting Started: Practical Next Steps for UK B2B Businesses

Take one representative order process through two shortlisted platforms. Use the same sample products, account rules and integration requirements, then compare the unresolved work as well as the subscription.

Before migration, record the existing URLs, valuable product content and redirects needed to preserve customer paths. Use the ecommerce platform migration checklist to plan the move and the UK ecommerce SEO guide to review product discovery.
