Vendor Resources

Purchase Orders 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:

invoicing@iit.edu
Phone: 312.567.3331

Fraudulent Purchase Order Activity

This is a notification to the vendor community. Please be aware of fake Requests for Quotation and Purchase Orders. Most recently, these have been sent out under email addresses "@iit-edu.org" and in the past from "@iitedu.us".  

Illinois Tech's email addresses are distinct and consistent, consisting of the person's name and followed by "@iit.edu". Please protect your interests by carefully examining the email address of any communication presented as coming from IIT.

IF IT LOOKS WRONG, PLEASE CALL OR EMAIL TO VERIFY. DO NOT SHIP FIRST AND THEN VERIFY.

Illinois Institute of Technology uses controlled documents for bid solicitations and for the issuance of purchase orders. Illinois Tech's Purchasing contact information is maintained on this website and is available for verification by Illinois Institute of Technology's Purchasing correspondence.
