B2B on Shopify: Building a Wholesale Portal Without Custom Backend Infrastructure

For years, brands selling both D2C and wholesale ran two separate platforms — Shopify for consumers, a clunky B2B portal or spreadsheet-based ordering for wholesale accounts.

Shopify Plus's native B2B framework changes that calculus. Company-specific catalogs, custom price lists per account, and self-serve ordering now live in the same admin as your consumer store.

The migration work isn't trivial — payment terms, tax exemptions, and minimum order quantities all need careful configuration — but the result is one platform, one inventory source, and one team managing both channels.

We've now built four of these for clients moving off dedicated wholesale platforms, and in every case the ROI showed up first in reduced order-processing time, not just lower software costs.
