Customers: Follow the instructions on this page to associate your billing account with that of your reseller. This adds your account as a sub-billing account in your reseller's project. Note that your reseller must first grant you permission to do this.
Log in to Google Cloud Console.
Click the navigation menu in the upper-left corner of the page, and select Billing.
In the top menu, click My Billing Account, then select Manage billing accounts from the drop-down menu.
Click the My projects tab.
Find your Premium project in the list, click the ellipsis , then select Change billing account.
Select the billing account shared by your reseller, then, click SET ACCOUNT.
Your project is now linked to your reseller's billing account.
If you have multiple SKUs (eg. Maps -INT, Maps-OEM) , multiple billing accounts have been created per SKU (eg. Billing account for Maps - INT, Billing account for Maps-OEM). We recommend consolidating these to use a single billing account.
