Team members who need to create their own Terra Billing projects, or view detailed cost breakdowns, can be added to the Cloud Billing account. Colleagues no longer in the group can be removed.This article walks through adding or removing users to the Cloud Billing account on Google Cloud console.  

What can Google Cloud Billing account users do?

It's not necessary to be a user on the Cloud Billing account to do work in Terra! Cloud Billing account users have additional permissions (below) and are typically admins or funding managers.

Why add collaborators to a Google Cloud Billing account

This approach shares responsibility for billing and gives additional users (beyond the PI, for example) more control over billing and costs, particularly creating separate Terra Billing projects to manage funding.

Note: To enable spend reporting in Terra requires admin or owner privileges on the Cloud Billing account. This step only needs to be done once per Cloud Billing account, so it's not a reason to grant permission to more team members than is necessary. 

Disadvantages to adding collaborators to a Google Cloud Billing account

Billing account users have more control; therefore, the process of removing them can be a bit more involved. For example, you need to transfer ownership or remove or disable all their Terra billing projects if they leave the team. You may not be familiar with those projects, although they will show up on your Billing page.
