Purchase Order and Invoicing
A purchase order (PO) is 亚色影库's preferred purchasing method for all University purchases. A PO will reference the University鈥檚 terms and conditions, payment term, invoicing instructions, etc. and is emailed to the vendor for fulfillment.
Vendors MUST reference the 亚色影库 PO number (starting with P or PE) on the invoice. 亚色影库 is not obligated to pay any invoice that does not reference a legitimate 亚色影库 PO/PE number indicating that it is an official University purchase.
Vendor invoices MUST be emailed to Accounts Payable for payment processing. Please note that invoices sent directly to the departmental requisitioner may experience delay in processing and payment. Accounts Payable's email address is:
