Hubstaff's integration with Active Collab allows your team to track their working hours and you can create automated reports. The integration works on all major operating systems.

Not only will you be able to track the exact time your team has been working, but you will also be able to see screenshots of what they are working on (up to three screenshots every ten minutes) and activity levels to show how active they were. It's all neatly organized so you can filter by date, team member, or project.
