Changing the Owner of a Client Account
In WHMCS 8.0 and later, users can own client accounts. This allows one user to manage products and services, billing, and other functions for multiple client accounts using a single login. You can change the client account owner to a different user easily in the Admin Area.
For more information about users and accounts, see Users and Accounts.
In the Admin Area
To make a user the owner of a client account:
1. Go to the Users tab in the client's profile.
2. Click Manage User next to the desired user.
If the desired user is not listed, see Adding and Managing Users.
3. Check Make Owner.
4. Click Save.
