As a system administrator, you can view a list of all the accounts assigned to an enterprise ID. The accounts control what services appear on the enterprise ID. After you view the list, you can create billing groups to make it easier to manage your accounts. If you have additional accounts that aren't in Control Center, you can add those accounts to this enterprise ID so you can see everything in one place. If you have accounts on another enterprise ID, you can also request those accounts be moved to this enterprise ID. You can also request a new enterprise ID if you need to segregate a set of accounts.
