TimeCard is the program for you if you need to track time and attendance. Enter your employees' times in and out for your specific pay period and this time tracking software does the rest.
Once the time off reasons and benefit rules are entered for your company, TimeCard calculates the number of regular hours and overtime hours employees have worked and tracks benefit hours employees earn and use. All according to your policies.
