Each voucher is recorded in the voucher register, as illustrated in Figure 10.22. The voucher register reflects the AP liability of the firm. The sum of the unpaid vouchers in the register (those with no check numbers and paid dates) is the firm’s total AP balance. The AP clerk files the cash disbursement voucher, along with supporting source documents, in the vouchers payable file. This file is equivalent to the open AP file discussed earlier and also is organized by due date. The DFD in Figure 10.14 illustrates both liability recognition methods.
