To approve timecards, go to TIMECARD & PAYROLL-> Review, Update and Approve Time Cards
Pick a department and you will see a list of yellow and green entries.
Green are approved, the employee clocked in based on the schedule and grace period you entered so we assume it is right (you can edit if need be).
Yellow need to be approved to be show in payroll reports or be exported to payroll. Beside the ‘paid’ entry is an icon of a pencil and paper, click it and edit the values.
