Accounts Payable (AP) allows you to enter supplier invoices for purchases that you make, then create checks for the invoices you want to pay. The system can generate payments for all invoices due, those for a particular supplier or only for specific invoices. If a supplier calls you to discuss an invoice, you will have complete information at your fingertips and that history can be kept indefinitely.
Accounts Payable allows you to update both purchase orders in Purchase Management as well as actual job costs. Adjustments are created if the purchase price does not match the invoiced price. With Accounts Payable, you will know how much you owe and when it is due.
