Create a Blanket Purchase Requisition

Last Updated on April 21, 2025

Blanket Purchase Requisition/Purchase Order – multiple payments to a single supplier for a specified period of time

• When repeated payments of the same type are expected, multiple purchase requisitions/orders may be eliminated by submitting one Purchase Requisition to establish a “Blanket Purchase Order”.
• Submit the purchase requisition as per the steps above, but enter the total amount expected to be paid to the supplier rather than a single payment amount. Once the purchase requisition is approved, the blanket PO will be created and the PO# will be assigned.  As payments are due, submit the supporting documentation, including the blanket PO#, to invoices@davidson.edu.  As payments are made, they will be applied to the PO, reducing the available amount.
• For example, if a contractor will be paid $500 per month for 6 months, the purchase requisition will be for $3,000.  A purchase order will be approved and the PO# assigned.  Each month, the supporting documentation for the $500 payment, is submitted to invoices@davidson.edu and the open balance of the PO will be reduced as each payment is made.
• If the PO has a balance after all the expected payments have been made, notify AP@davidson.edu to close the PO.
