Vendor Invoice Certification Quick Reference Guide

Vendor Invoice Certification

Beginning on the evening of June 13, 2025, all IPP vendors will be required to certify invoices prior to submission. Per Treasury regulations, this change updates the agreement terms to ensure that all invoices submitted are accurate, complete and represent a valid claim for payment.

New Submission Confirmation Page

After completing the invoice and pressing submit the submission confirmation page will pop-up.

Once you have checked the box, the confirm or cancel buttons will become accessible. You must confirm for your invoice to successfully submit. You will not be able to submit invoices without confirming.
