Invoicing Instructions
IIT allows use of an IIT issued procurement card for purchases up to $1,000.
If a procurement card is not being used, IIT requires use of a purchase order for all purchases of $500 or more.
All invoicing for purchases of $500 or more should:
- Clearly be identified as an invoice
- Show the "remit to" address
- Reference the IIT purchase order number
- Provide information regarding the quantities, description of goods and/or services provided; the unit cost; and the total amount due.
- Be mailed directly to:
IIT Accounts Payable Department
Main Building, Room 201
3300 S. Federal Street
Chicago, IL 60616
IIT does not issue purchase orders for purchases under $500. Invoices for these purchases must include information to identify the person who placed the order and the receiving department.
Vendors that are new to IIT must fill out an IIT Substitute W-9 Form. Instructions are on the form.
