To have somebody in-house who’s going to have to sit down and go through the time cards and calculate hours and calculate PTO. When you can have systems in place that people punch in. These systems are so sophisticated that it’ll let the supervisor know who might have missed a punch.
They even approve PTO time so it automatically goes into the system. The times then get dumped into the payroll portion of the software and employees are paid with little or no effort on in-house staff.
