Invoice Payment Information

The Department of Accounts Payable has responsibility for paying invoices associated with a USC Purchase Order.

To expedite the processing of an invoice, please follow these tips.

1. Create either a Paperless Requisition or a Form Requisition.
2. When you have your Purchase Order Number, please give the Purchase Order Number to your vendor and then place your order.  Vendors should not place an order without a Purchase Order Number.
3. When payment is due, the vendor should submit all invoices referencing the Purchase Order Number directly to Accounts Payable (see invoice submission options, below).   Invoices should not be submitted to departments.  This added step delays payment. 
4. If the invoice exceeds $5,000, the department will be contacted to confirm the order was satisfactorily received. Upon receiving confirmation, the invoice will be paid.
5. If the invoice is less than $5,000, the invoice will be paid without contacting the department.
6. Accounts Payable will process payment within 10 business days of receipt.  If faster payment is necessary, please see instructions below.

Note:  Invoices without Purchase Order numbers cannot be paid.  Invoices associated with a Purchase Order with insufficient funds can only be paid once a change order has been submitted to Purchasing Services to increase the funding on the PO.   Invoices associated with a closed/frozen sponsored project account cannot be paid. The account either needs to be reopend by Sponsored Project Accounting or a change order associated with a new account must be processed.
