What is a Delivery Order?
Also known as: DO
By the GovPrimer teamUpdated January 1, 2026
Definition
A delivery order is an order for supplies or products placed against an existing indefinite-delivery contract such as an IDIQ or GSA Schedule. The base contract sets pricing and terms; the delivery order specifies the items, quantity, and delivery.
01Section
Delivery orders in practice
Like task orders, delivery orders let agencies buy quickly from vendors already on a vehicle. For product companies, a steady flow of delivery orders against a Schedule or IDIQ is a reliable revenue stream.
Frequently asked questions
Can I get a delivery order without being on a contract vehicle?
Generally no. Delivery orders are issued against an underlying IDIQ, GSA Schedule, or BPA — you must hold that base contract to receive orders.
