Purchase Order and Invoicing
A purchase order (PO) is Illinois Tech's preferred purchasing method for all University purchases. A PO will reference the University’s terms and conditions, payment term, invoicing instructions, etc. and is emailed to the vendor for fulfillment.
Vendors MUST reference the Illinois Tech PO number (starting with P or PE) on the invoice. Illinois Tech is not obligated to pay any invoice that does not reference a legitimate Illinois Tech 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:
