After labor hours are entered for a pay period, the Calculate Payroll process, selected from the Data Entry, Payroll menu, generates payroll vouchers for the pay period. Only one pay period can be processed by each run of the process. If a pay date is the end of more than one pay period, e.g., semi-monthly and monthly, each pay period must be run separately. The order in which pay periods are processed is not important. The payroll calculation process produces a set of vouchers which can be edited using the voucher screen and paid using choices from the Payroll Payments utilities.
