Google Ads has added new access levels and roles for more flexibility with what users can see and manage in your Google Ads account. Google added new billing-only role and an update to account ownership role.
With the billing-only role you can now grant billing permissions to certain people, such as people in your finance department. These billing-only roles will have the ability to view and manage billing, but won’t be able to view or edit your campaigns.

Here is the grid of various levels of access:
