Change Orders

Vendor Requested

Change orders are often requested by vendors that require changes or cancellations. After consultation with the principal investigator or initiator, an acceptance or counter offer of the change will be documented by issuing a written change order.

Initiator Requested

Principal investigators must convey their requests for changes or cancellations to a purchase order by submitting a requisition to Procurement, listing the purchase order number in the space provided on the requisition form and indicating on the first line in the body of the form that a change order is requested. The change, additions, or deletions must be listed. Procurement will then issue a change order to the vendor.
