In company settings under the ‘Access Permissions’ tab you can set permissions for each of the different user roles. For example, Admin, installer and engineer can have access to different things. 

• Within the roles if you want the user to have access to all of the features, select the checkbox ‘Has Access To All Features’

• Or if you don’t want a user having access to everything, using the tick boxes you can select what they are able to see and do. If they are not being given permission, leave it unticked.
