Builders with admin access are able to add, edit and remove builder-side users by going to Contacts > My Team.
Admin users will always have access to all projects as well as all permission access for viewing financial information and the ability to update templates and schedules. Non-admin users can also be given full access and permissions or can be restricted by using the options on the Account Settings page.
Only admin users will be able to access your Accounting Settings. This includes setting up accounting codes, time entry types and PO variance codes as well as setting up and maintaining any accounting integration functions.
In addition, only admin users can add and edit Jobsite Log flags. To do that, go to Settings > Account Settings and select the Jobsite Log tab.
