Accounts Payable



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

                P.O. Box 18158

                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 directly 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

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.
