Change Order

A change in specifications, price or terms may necessitate an amendment (change order) to a purchase order. Changes may be initiated by the vendor, the requesting department or the NMU Purchasing Department.


  1. The requestor advises the Purchasing Department of a change in the order by providing a purchase requisition referencing the original purchase order number, the vendor name and stated changes.
  2. The vendor notifies the Purchasing Department of a change. The Purchasing Department generally approves minor changes immediately and notes them on the purchase order. For significant changes, the Purchasing Department contacts the requestor who either accepts or refuses the change. If accepted, the requestor shall provide a change order to the Purchasing Department.
