Account ownership can be transferred by the account owner to another person on the account.
NOTE: The ownership can only be transferred to an active user (a user who has accepted their invite). If you have recently invited a new user, you will have to wait for them to accept the invitation before you can transfer the account ownership.
Choose 'Manage users' from your business menu.
Select the 'Transfer ownership' button at the bottom of the screen.
Use the drop-down menu to choose a new owner from the list of personnel on the account.
