IDIQ
Indefinite-Delivery/Indefinite-Quantity contract
An Indefinite-Delivery/Indefinite-Quantity (IDIQ) contract provides for an indefinite quantity of supplies or services over a fixed period, ordered through individual task or delivery orders. It lets the government award once and buy repeatedly without re-competing the base contract.
What it is
An IDIQ sets terms, ceiling values, and (usually) minimum and maximum quantities, then work is ordered against it via task orders (services) or delivery orders (supplies). It can be single-award or multiple-award, where holders compete for each order.
Why it exists
It gives agencies speed and flexibility for recurring or uncertain requirements — the heavy competition happens once at the base award, and orders follow quickly.
Who it applies to
Contractors pursuing federal work at scale. Winning an IDIQ seat is often the gate to a stream of task orders rather than a single job.
