Invoice Procedures

MTSU directs vendors to email invoices to invoice@mtsu.edu. Departments may ask vendors to send invoices to them directly, but vendors must include invoice@mtsu.edu in the final invoice e-mail correspondence. Accounting Services must pay from the original document as part of the University’s internal control procedures for audit review purposes. When e-mail delivery is not possible, vendors may mail the invoice to MTSU Accounting Services, CAB 106, 1301 East Main St, Murfreesboro, TN 37132.


For international wire payments, vendors should send wire instructions directly to invoice@mtsu.edu or utilize other means as directed by Accounting Services.

Departments should create a receipt in the Procurement system for purchase order invoices for any amount on the applicable purchase order. Faculty and staff should submit non-PO Invoices under $500.00 for approval via the Payment Authorization (Other Purposes not Specifically Identified).
