Customers can track their GCP usage and view their estimated bill using the Google GCP Dashboard and by clicking on the Billing page. See GCP's Cloud Billing Reports documentation for more detail.
To change UW Billing information (D# and/or UDDS code) for your account, email firstname.lastname@example.org with the account id and the new information.
To have a spending quota assigned to your subscription, please Contact the Public Cloud Team (AWS, Azure & GCP) .
Please note that the usage and bill details in the GCP Console provide an estimate of charges; the actual invoice will come from DoIT Billing.
