What Shopify B2B Development Includes

Shopify now ships native B2B features for Shopify Plus merchants, but enterprise wholesale programs almost always need configuration, custom apps and integrations on top of them. A Shopify B2B development agency typically handles:

• Company accounts and buyer roles: setting up company profiles, multiple locations and buyer permissions so each customer sees the right catalog and can order on behalf of their business.
• Catalogs and pricing: customer-specific price lists, volume and tiered pricing, quantity rules, minimum order quantities and gated products.
• Payment terms and checkout: net terms, draft orders, purchase order numbers, deposits and approval workflows that reflect how B2B buyers actually pay.
• ERP, CRM and PIM integrations: syncing inventory, orders, customers and pricing with systems such as NetSuite, SAP, Microsoft Dynamics or a PIM, which is usually the largest part of the project.
• Blended B2B and DTC setups: running wholesale and direct-to-consumer on one store or on expansion stores, with shared products and separate rules.
• Migration and replatforming: moving customer accounts, order history and price lists from Magento, BigCommerce, Salesforce Commerce Cloud or a legacy wholesale portal.
• Buyer experience: quick order forms, reorder lists, account dashboards and fast search for large catalogs.

Frequently Asked Questions

What does a Shopify B2B development agency do?

A Shopify B2B development agency designs, builds and integrates wholesale stores on Shopify. The work usually covers company accounts, customer-specific catalogs and pricing, payment terms, ERP and CRM integrations and migrations from older platforms. Many agencies also handle ongoing optimization once the store is live.

Does Shopify support B2B wholesale features?

Yes. Shopify offers native B2B features that include company profiles with multiple buyers and locations, custom catalogs and price lists, volume pricing, quantity rules and net payment terms. More complex needs, such as quote workflows or deep ERP syncing, are usually added through apps or custom development.

Do you need Shopify Plus for B2B?

Shopify’s full native B2B feature set is built for Shopify Plus, so most enterprise wholesale programs run on Plus. Smaller wholesalers can handle simpler B2B selling on other Shopify plans with apps, but they give up features such as company accounts and custom catalogs managed inside Shopify. An agency can help you judge which setup fits your order volume and pricing complexity.

Making An Enterprise-Ready Choice

Set the target first: contract pricing, gated catalogs, quantity rules, and self-serve reorders that actually stick. Then match teams to your stack, not the other way around — the best Shopify B2B development agencies in 2026 can meet you where you are, whether you run SAP, NetSuite, or a homegrown ERP. Proof points matter: certifications, shipped migrations, and references with real numbers.

If you need exports, integration reliability, and governance you can audit, pick for process and cadence — not just a clever pitch. Shortlist two or three candidates, ask for a discovery plan, and insist on measurable milestones. With the right partner from the top Shopify B2B development agencies in 2026, your buyers will spend less time navigating friction and more time ordering, which is the point.
