Note about preventing self-registration in account-based storefronts

In account-based storefronts, accounts are created manually by merchant administrators in Commerce. Therefore, storefronts that support account-based contacts must be careful not to allow this type of contact to self-register.

To accommodate this use case, the example in the Example for restricting guest checkout section would need to be modified to restrict account-based contacts to logging in only. For storefronts that support both individual, registered shoppers and account-based contacts, your UI will have to make it clear that the self-registration process creates a personal account only, not a business account.
