What is a Task Order?

Also known as: TO

By the GovPrimer teamUpdated January 1, 2026

A task order is an order for services issued under an existing IDIQ or other indefinite-delivery contract. The base contract sets the ceiling and terms; each task order defines the specific work, funding, and period of performance.

How task orders are competed

On a multiple-award vehicle, the agency typically issues task-order solicitations to the contract holders, who then compete. Because the pool is limited to awardees, task-order competitions are smaller and faster than open-market procurements.

Task-order wins are where most of the real revenue on an IDIQ is captured — so contractors monitor order activity closely after getting on a vehicle.

Frequently asked questions
