Electronic Invoicing

Electronic Invoicing (EI) is a new feature of our iBuy system, created to streamline the purchase order (PO) invoice submission process. This new automatic process allows the vendor to convert or “flip” the PO into an invoice, resulting in real-time invoice submissions, reduced errors, and timely payments.

How does Electronic Invoicing Work?

  1. Vendor enrolls
  2. iBuy PO is created
  3. Vendor receives PO and invoicing link
  4. Vendor submits electronic invoice
  5. Vender receives confirmation email
  6. Invoice enters workflow
  7. Payment is approved

Advantages of Electronic Invoicing

Electronic Invoicing offers several benefits for both our vendors and the University:

  • “Flipping” the PO into an invoice will bring efficiency and reduce errors
  • No additional technology or log-in information is needed by the vendor
  • Invoice submission is digital (electronic) and instantaneous – no delays with USPS mail or misdirected emails
  • Invoice flows directly into iBuy for review
  • All documentation – from requisition to payment – is found in iBuy
  • Virtually touchless processing promotes accurate and timely vendor payments
  • “Green technology” reduces paper usage and saves money in overhead costs

Vendor Enrollment

To enroll in Electronic Invoicing, vendors should complete the University of Illinois Electronic Invoicing Registration form. Once enrollment is completed, University Payables will send a confirmation email to the vendor with a copy of the vendor job aid and further instructions.

Unit Responsibilities

Units have the following responsibilities in processing e-invoices:

  • e-Invoices which total  $50,000 or more will route to the department Invoice Acknowledgers for payment approval. Set up and maintain at least two Invoice Acknowledger roles in iBuy through your Unit Security Contact (USC).
  • Respond to UPAY or Purchasing via the iBuy e-Invoice Comments function to inquiries regarding price discrepancies and over tolerances.
