Organizations can send invitations to staff members, allowing them to create admin accounts. When you receive your invitation, you will have seven days to use it to create your username and password. Then, you can log in to the Admin Area to start working in WHMCS.
Add an admin account for each of your staff members. You can choose to set their credentials for the new admin or, in WHMCS 8.12 and later, you can send an invitation link.
