ExakTime Feedback Needed

We are using Sage 100 Contractor and currently looking at purchasing ExakTime software. We would be using it for time reporting for remote field employees as well as for office personnel. I need to know if anyone has experience using this product and if so are you using is exclusively with job numbers AR module) or is anyone using it with job numbers and work order numbers (Service module). We need to enter both ways and want confirmation that it will work.
