Three types of users potentially have the ability to update your billing information. Each type has unique access: Admins, Editors with billing access, and the person whose billing email is on file with Stripe.
All admins will have access to billing features.
Editors by default do not have access to billing details. However, the first the first user that adds a card and creates a subscription is given special permissions to edit billing, while remaining in the Editor user role. They now have additional permissions to edit billing information.
