Invoice Payment Information

Payment Services - Accounts Payable has responsibility for paying invoices associated with a USC Purchase Order.

1. Vendors 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 can delay payment.
2. If the invoice is $5,000 or more, the department will be contacted to confirm the order was satisfactorily received. Upon receiving confirmation, the invoice will be processed for payment.
3. If the invoice is less than $5,000 and associated with a purchase order with sufficient funds, the invoice will be processed for payment without contacting the department.

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 Purchase Order. Invoices associated with a closed/frozen Sponsored Project Account cannot be paid. The account must be reopened by Sponsored Project Accounting or a change order associated with a new account must be processed.
