How to Transfer a Google Ads Client Account to a New Agency (Billing Transfer)
This guide outlines the steps required to transfer a client account from an existing manager account to a new manager account. For example, if an agency needs to transfer a client to a new agency, this process is the standard method.
If your Google Ads account is currently set up with monthly invoicing and you would like to transfer it to a new agency that also uses monthly invoicing, you will need to perform a Billing Transfer (also known as Change Who Pays).
The current agency must initiate the billing transfer, and the new agency must accept the request.
