Subrecipients send their invoices for payment to the ORSP Sponsored Programs Accountant, who reviews each invoice with regard to federal and state regulations and conditions specified in the award. If an invoice is acceptable, the Accountant attaches and signs an approved Certification for Payments to be Made under a Subcontract form and forwards the certificate and invoice to the PI/PD for approval. The PI/PD is responsible for approving all invoices with regard to the subcontractor’s performance. The PI/PD then sends the form and invoice to the Office of Procurement Services to be paid. The Office of Procurement Services will not pay a subcontractor’s invoice without both signatures (ORSP Sponsored Programs Accountant and PI/PD) on the certification form.
