The Contract Payment Form is used to generate purchase orders against a contract to encumber funds and facilitate the processing of invoices and payments. The Contract Payment Form should be established after Purchasing Services has generated your contract, and before payments against the contract are to begin.
If you wish to encumber the full value or the contract, the Contract Payment Form needs to be entered just once for the life of the contract. However, with a multi-year contract or a contract that can have varying usage, user can enter use the Contract Payment Form to only encumber funds (and thus allow payment) for the current fiscal year or term.
