Change Orders

The purpose of a change order request is to make official changes to an existing purchase order (PO). Change orders are processed directly in CSUBUY.

When to submit a change order

Department users should submit a change order request to:

  • Increase or decrease the dollar amount on a blanket PO.
  • Change the unit price, quantity, description or chartfields on a PO line.
  • Add a new item/line to a purchase order.
  • Close a PO line/purchase order.
  • Cancel a PO line/purchase order entirely.


If you aren't sure whether this applies to you, you can review the Encumbrance Checklist [pdf] to determine whether you have any Purchase Orders that are pending payment or ready to be closed.

Change order requirements
  • Must be approved by the appropriate Dept. Approver. 
  • Upload backup documents to support the action requested (e.g., supplier quote, invoice, updated scope of work).
A change order cannot be processed if...
  • A PO that was not competitively bid goes over the $50,000 threshold.
  • A PO for Temporary Staffing Services that exceeds the 180 days. Please see Special Approvals for details.
  • The PO is closed.
