gcloud billing projects link

NAME
gcloud billing projects link - link a project with a billing account
SYNOPSIS
gcloud billing projects link PROJECT_ID --billing-account=ACCOUNT_ID [GCLOUD_WIDE_FLAG]
DESCRIPTION
This command sets or updates the billing account associated with a project.

Billing is enabled on a project when the project is linked to a valid, active Cloud Billing account. The billing account accrues charges for the usage of resources in all of the linked projects. If the project is already linked to a billing account, this command moves the project to the billing account you specify, updating the billing account that is linked to the project.

Note that associating a project with a closed billing account has the same effect as disabling billing on the project: any paid resources in use by the project are shut down, and your application stops functioning. Unless you want to disable billing, you should always specify a valid, active Cloud Billing account when you run this command. Learn how to confirm the status of a Cloud Billing account at https://cloud.google.com/billing/docs/how-to/verify-billing-enabled#billing_account_status
