The billing details don’t have to be the same as the Account Owner’s details, and can be different for each ApprovalMax subscription.
This is how you change a billing address
Click on Billing & Subscriptions under your avatar in the top right-hand corner:
Go to the Subscriptions tab.
Under Billing Address, click on UPDATE DETAILS button:
Fill in the details and click on SAVE:
Please keep in mind that the new billing address will only be applied to future invoices, not to previous ones.
