The most useful feature of this tool has to be its flexibility in terms of how you can segment your data for individual employees or departments as well as by client project/contracting situation. It's easy enough that even junior people should have no issue using it but powerful enough if someone needs more advanced tools and features. Sometimes I would like there was an easier way to export all my reports at once without having so many tabs open. But with such robust reporting options (including Pivot Charts), I don't really see why anyone wouldn't want this program! We've been able to track employee hours worked per week & month since we implemented their services 3 years ago now. With just one click they are able to access each day's work schedule.
