Accounts Payable

Vendor Information

The Accounts Payable Department sets up vendors in our system to provide for the timely payments of invoices. This requires the coordination between the university and our vendors.

USI Billing Address

W-9 Requirement

USI Billing Address

All invoices to be paid by the University of Southern Indiana must be addressed as follows to receive proper handling:

  • University of Southern Indiana
  • Attn: Accounts Payable
  • 8600 University Blvd.
  • Evansville, IN 47712

  • The University will not be bound by the terms of any invoice mailed or delivered directly to another University employee or department. Accordingly, vendors who elect not to route invoices irectly to Accounts Payable may experience significant payment delays.

    Vendors may opt to send invoices by email rather than postal mail, but must choose to invoice exclusively by one method or the other. Electronic billings should be sent to AcctsPay@usi.edu.

    Many times, when an invoice is mailed to another department, it is not forwarded to Accounts Payable in a timely fashion; therefore, prolonging payment. If the invoice is not addressed in this manner, you may expect delays in payment processing.

    W-9 Requirement

    The University must obtain certain information about the tax status of our vendors as required by Internal Revenue Service regulations. To meet those requirements, a completed Form W-9 (Request for Taxpayer Identification Number and Certification) must be on file for all vendors, with the following exceptions:

  • Payments to USI employees
  • Direct refunds of income
  • Payments to foreign persons (including nonresident alien individuals, foreign corporations, foreign partnerships, foreign trusts, foreign estates, and any other person that is not a U.S. person as defined by the IRS)*
  • IRS Form W-9 is available at http://www.irs.gov/pub/irs-pdf/fw9.pdf?portlet=3
    *Instead of Form W-9, these payments require completion of the appropriate Form W-8.
