To change your billing address and payment information, first log into your site.
Next, open the Website Management bar and click Account Center under Billing & Support.
In your account center, click Billing Information.
Enter your password, then click Proceed.
Enter your information in the available fields. After making changes, click Save Information.
Note: You must fill in all fields, even if only one field needs to be updated.
You'll see the updated billing information in the Account Center.
Tip: If the Account Center shows a "This is a Managed Account" message, your site is a sub-account. Contact the master account owner to make billing changes for your site.
