Invoices

For all non-Procurement Card purchases, an Illinois Tech Buy It Purchase Order (starting with PE) is required for invoice payment.

All invoicing for applicable and legitimate University purchases MUST:

1. Clearly be identified as an invoice
2. Show the "remit to" address
3. Reference the Illinois Tech Purchase Order number
4. Provide information regarding the quantities, description of goods and/or services provided; the unit cost; and the total amount due
5. Be emailed directly to invoicing@iit.edu

After-the-Fact Purchase Order Invoices

After-the-fact POs or Buy It retrofit orders issued solely for the purpose of paying an invoice for goods or services already received/performed is not compliant with policy and is highly discouraged.

Not only is after-the-fact POs / retrofit orders not policy compliant, engaging the vendor before a purchase order is in place also:

• Exposes the University to potential risks
• Is a bad budgeting practice, when funds are not encumbered, departments are more likely to run into an NSF (Insufficient Funds) situation
• More likely to lead to vendor invoices not getting paid on time
• Create additional work for departmental and Accounts Payable resources
