Shopify

What it does

Shopify handles the full commerce stack — product catalog, checkout, payment processing, inventory, shipping, and an enormous app ecosystem for extending functionality — with both online storefronts and in-person POS hardware under one account. Its Partner Program is a major channel in its own right: agencies build and manage client stores through it, earning recurring revenue share separate from the simpler consumer affiliate program.
