To ensure proper, prompt payment, all purchase order and standing order invoices must:

• be itemized;

• be submitted in duplicate (original and one copy);

• include the current purchase order number (a six-digit number with a one- to three-letter code after the number) located in the upper right corner of the purchase order.

Invoices submitted without the above information will be returned without payment.

Invoices should be sent to the “Bill to” address on the order.

Material or services should not be provided without an authorized standing order, purchase order, or limited order, and should not exceed the dollar amount stated on the order.

To inquire about the status of a payment, please contact the Payables Clerk for your commodity. For a list of Payables Clerks and their commodity responsibilities, see our Commodity Directory.
