How can I update my billing address/card details?

If you simply click on your initials on the very right-hand side of the black top bar, you can then click on Settings and Company Settings > Billing. You will be able to add or update your card details at the bottom of this screen.

Editing your company’s billing address would be available for eDesk account owners only and would be done via Settings and Company Settings. Then select Manage Billing Details.
