Our company would like to setup open source OT management system that allows us to do following:
1. When employ wants to do OT, Start time must be submitted first and then it will only be reflected to system once administrator approved.
2. Later when employee finish job, he or she can set the end time, and there should be something that allows emplyee to upload service report that contains start and end time signed by our customers.
3. After setting end time, it should show total OT - hours and we should be able to generate monthly OT for each employee.
Plz advise something that is opensource or even if need to pay, it should be something not very expensive.
