If you have more than one person responsible for administering your main Saffas account then you may want to provide each user with their own password and personal level of privileges. In which case, you can set up a sub-account user.
You can determine the permission levels for each sub-account which means each new user will be able to access and administer only the levels you give them permission to access.
For example ...
your accounts department may need to access invoices and payments
your sales team may need to access the domain and hosting plans
your technical team may need to access the ticket support area
