Billing & Payment

As part of our commitment to sustainable purchasing, we encourage suppliers to help reduce paper usage by emailing invoices to psuinvoices@psu.edu.   To ensure proper, prompt payment, all invoices must:

  • be itemized;
  • include the current purchase order number and PA code located in the upper right-hand corner of the purchase order

Invoices submitted without the above information will be returned without payment.    Please also include the purchase order numbr and PA code on the subject line of the email.

Invoices may also be sent to The Pennsylvania State University, Purchasing Services, 101 Procurement Services Building, University Park, PA, 16802. 

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 on your order.  For a list of Payables clerks and their commodity responsibilities, see our Commodity Directory.
