  2. The Office of the Comptroller is responsible for maintaining an effective and efficient disbursement system which ensures the complete, accurate and timely payment of all valid purchase order invoices.

  3. Invoices processed for payment must represent goods received and/or services rendered in a manner acceptable to the University. Checks or other forms of payment will be prepared only for payment of original supplier invoices which reference an approved purchase order.

  4. The University’s purchase order instructs suppliers to send invoices directly to Accounts Payable for payment. Invoices received by a department must be forwarded immediately to Accounts Payable in order to ensure timely payment to the supplier. The department must contact the supplier and have them change the “send to” address to 440 Franklin Bldg, 3451 Walnut Street, Philadelphia, PA. Accounts Payable prefers receiving PO invoices via email (poinv@upenn.edu). Invoices must be in a pdf file format, one invoice per file and the PO # must be on the invoice.

  6. Payment of invoices associated with purchase orders of $10,000 or more will not be processed until an electronic receipt, confirming that the goods and/or services included on the invoice were received in an acceptable condition, has been entered into the University Purchasing System. Departments may choose to mark a supplier for receipt required for invoices less than $10,000.
