Submitting an invoice

Material or services should not be provided without an authorized purchase order and should not exceed the dollar amount stated on the order.  Invoices must match the PO as issued in both quantity and pricing.

Please submit itemized invoices to [email protected] according to the Invoicing Terms and Conditions. Invoices submitted without the requested information below will be returned without payment:

  • Business name
  • Supplier name
  • Invoice date
  • PO number
  • Remit to address
  • Line items match PO
  • Invoice number (if applicable)

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

To inquire about the status of a payment, please email [email protected].

Purchasing Card Transactions

Penn State Purchasing Card transactions are handled like any other standard Visa charge. If you are currently Visa capable, you do not need to take any further action in order to participate in the Purchasing Card program.

To begin a Visa program, contact your financial institution or PNC Bank (1-800-685-4039 or 1-888-562-2300).

Things to keep in mind

  • You must provide cardholders with an itemized receipt or a priced packing slip.
  • Do not send Penn State an invoice for purchases made with the Purchasing Card.
  • A purchase made with the Purchasing Card requires only a receipt or priced packing list; it does not require an additional invoice from the supplier.

PAYMENT AND TERMS 

All suppliers must register in PaymentWorks before Penn State procures a good or service.  Currently, a paper check is the default payment method for approved suppliers.  However, PaymentWorks allows suppliers to choose their own payment method, including Automated Clearing House (ACH), a direct deposit in a bank account.
