Open General settings
Click Settings in the sidebar and open General. The Customer registration option appears with the account details and business hours.
Choose who can register
Leave Allow customer registration selected when anyone with your customer-site link should be able to create an account.
Clear it when staff should create customer records or send access only to known customers.
Save and verify
Click Save Changes. Open the customer site in a private browser window and confirm the registration option matches your choice.
Existing customers can still sign in when new registration is disabled.
Tip Turn self-registration off for invite-only programs, then add customers from the admin Customers page.
