Self-registration for a B2B store
Key Takeaway
Self-registered users get products and prices through a buyer group. If you don't select a default buyer group, they can log in but see no products or prices until you assign them to a buyer group.
Self-registration lets a customer create their own account on a B2B store and then log in with it, instead of browsing as a guest. In some orgs, self-registration is turned on automatically. Otherwise, an admin sets it up in three places: Experience Builder (the Register page), the site's membership settings, and the store's Buyer Access settings in the Commerce app. The buyer group a self-registered user joins controls which products and prices that user can see.
When self-registration is turned on automatically
If you configured your org with the Commerce Setup Assistant and Person Accounts are enabled...
Self-registration is turned on automatically when you create a store. You don't need to enable self-registration manually.
If self-registration isn't already on for your store...
You enable self-registration manually in Experience Builder, in Setup, and in the Commerce app.
