Missing punch is common. We have multiple controls and notifications in place to help reduce the risk of this happening, but it still does. There are error messages that are triggered for the employee and supervisor to see as soon as it happens. Also, a report to run at the end of the pay period to try to make sure any that are still not fixed are caught prior to the pay actually being processed. We also require supervisors to approve timesheets and reminder messages go out each pay.
