Updating your payment information in the byDesign Workspace is a breeze. This can only be done by Project Managers.
If you're a Project Manager, navigate to User & Team Settings in the left navigation bar to the right of your profile picture. Scroll all the way to the button of the pop-up and select Change Payment Method. A pop-up will appear, requesting the new payment information. Click Save Information to save this card to your account. This card will now be the default for all future charges.
