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).

A vendor submits invoices to request payment for goods or services. A valid invoice includes all of the following:

  • Invoice Date
  • Invoice Number
  • MTSU Purchase Order number (unless exempt under small-dollar purchase rules)
  • The amount payable
  • The vendor/supplier’s name
  • Vendor’s verifiable business address and payment remittance address (if different)
  • A detailed description of all goods or services provided
  • If applicable, wiring instructions should also be included.

Please note that all hand-written invoices require the vendor’s signature for authentication.

Accounts Payable does not accept the following as an invoice:

  • Proforma Invoices
  • Written Quotes
  • Packing Slips
  • Statements

  • Sponsorship payments require vice president approval. Marketing and Communications should also review the sponsorship advertising before a payment can be completed. E-mail approvals are sufficient and may be attached to the purchase order or payment authorization.
