How do I update my card details?

For Professional subscription plans, account architects can update your card details via your Billing page.

Enterprise plans are settled via invoice. 

Your billing page can be accessed by clicking on "Account settings" in the profile image pop-out menu, located at the bottom of the main left hand column navigation bar and then "Billing". 

To update your card details, in the "Billing details" box against "Payment method", click the "Update" link to update this information.
