Every supplier is accountable to meet the requirements and past satisfactory performance may not be a guarantee of acceptability in the future.

Suppliers who do not comply with the requirements may find limited future business with MSU, and may also experience late payment or non-payment. Three conditions in particular must be noted:

  • Order fulfillment requires a corresponding purchase order (PO) or MSU Procurement Card.
  • Prior written approval of Purchasing is required for any changes in the delivered product or service.
  • Invoice requirements must be satisfied to receive payment.

Supplier Eligibility
All prospective suppliers are eligible to solicit business from MSU. Purchasing selects the suppliers who meet the requirements of each request for quotation /proposal. All else being equal, MSU gives preference to local suppliers in its campus communities.

Only Purchasing may authorize a supplier to provide goods or services via issuance of a PO; verbal authorization from departmental representatives without signature authority will not be recognized and may put the supplier at risk.

Changes to POs
Any change in the product or service provided by a supplier from that specified in the PO must be approved in writing by MSU Purchasing via a PO amendment (POA) before the supplier provides the goods or services. Changes include but are not limited to description, quantity, price, or terms which differ from the original PO.

Terms referenced in the PO are based on date of receipt by Accounts Payable, by default. If deeper discounts are available, more expedient payment can usually be arranged.
