Billing settings can be accessed by the account owner and by teammates who have been given the appropriate permissions.
If someone on your team needs access specifically to billing, you can invite them as a teammate and assign the Billing Admin access level.
To do this:
A Billing Admin can manage the subscription, payment methods, and invoices, but does not have access to campaigns or other account settings.
You can also assign Account Admin access if the teammate needs broader access across the account, including billing.
If you add a separate Billing Email, that person will receive invoices and payment receipts, but this does not automatically give them access to your Referral Factory account. If they need to log in and manage billing, they should also be added as a teammate with the appropriate access level.
