Viewing Billable Users for a Tenant

You can see exactly which users are billable for any tenant directly in the Petra dashboard.
  1. From the Homepage, click on a tenant to open the tenant page.
  2. Scroll down to the Admin panel.
  3. Select the Users tab.
  4. Toggle Billable Only on to filter the table to only billable users.
The table will now show only the users that count toward your billable license total. You can also export the filtered list by clicking the Export button in the top right of the Admin panel.
