There are multiple type of user roles available in the system. User managment section for all type users gives complete controll over users. Each user role can be controlled through the permissions wizard by setting correct permissions for your user roles.
More flexible permissions to different user roles give you the complete control over the users. Depending on your business model you can configure the permissions for branches and staffs to control what they can see and edit. Setting correct permissions protects your business data from getting removed and misused by your company employees.
