How to build a B2B wholesale portal with Shopify and Webflow

Building a Shopify B2B wholesale portal with a Webflow Cloud front end requires Shopify B2B setup, customer accounts, Storefront and Customer Account API access, and a server-side Next.js layer that securely manages authenticated buyer context. Personalized pricing depends on both a customer access token and a selected company location ID, which must be supplied through Shopify’s contextual Storefront API queries to return negotiated prices, quantity rules, and volume price breaks. Shopify’s lower plans support limited market-assigned B2B catalogs and shared pricing tiers, while Plus is required for catalogs and pricing assigned directly to individual companies or locations. Because B2B catalog data is customer-specific, routes returning it must avoid all caching through dynamic rendering, no-store fetch settings, and private response headers to prevent pricing exposure between buyers. Carts must also include the same buyer identity so wholesale pricing persists through checkout, and implementations should test distinct buyer accounts, location changes, and checkout totals. Common problems include missing query context, expired tokens, cached responses, unsupported plan capabilities, and Webflow Cloud deployment failures caused by the unsupported Next.js edge runtime directive.
