Accounting Office / Accounts Payable

The Accounts Payable function within the Accounting Office processes approximately 60,000 invoices each fiscal year that are authorized by purchase orders. Issuing a check to an external vendor generally requires a purchase order. Exceptions include registration fees, subscriptions, memberships, utilities, airline tickets, and purchases made with a P-Card. Please refer to the Procurement Services Website for information on the procurement process.

The Accounts Payable function within the Accounting Office is responsible for:

We strongly recommend that all invoices be mailed to Accounts Payable, Iowa State University, 1520 Administrative Services Building, 1220 Wanda Daley Drive, Ames, IA 50011-1004, faxed to 515-294-6470, or e-mailed as attachments to invoices@iastate.edu. Invoices sent to the correct address and bearing all the required information will be paid promptly. Delays in processing can cause lost discounts and strained relations with vendors.

Invoices must include a valid purchase order number. The lack of a valid purchase order number requires manual research by Accounts Payable and Procurement Services to determine the funding source, which delays the payment process.

To avoid duplicate payments, we prefer to pay from the individual invoices rather than the statement.

Iowa State University prints checks on Monday through Friday nights, which are mailed the following business day.

If you have questions about the payment status of an invoice, please contact one of the following people:
