There a four different staff access levels on the system - here is an explanation of the options:
Guest: can access all of the system (apart from the Templates tab) but can only view data, they cannot add or edit any data.
Trainee: can access all of the system (apart from the Templates tab) and can edit contacts and properties but cannot add new data to the system or delete data.
Staff: can access all of the system, including the Templates tab, where they can edit existing templates but cannot add new templates. They can also edit their own staff user details but cannot add or edit other staff users.
Manager: has full access to the system.
