What is an IDIQ contract?
An IDIQ (indefinite delivery, indefinite quantity) contract is a US government contract vehicle that lets an agency order an unspecified quantity of goods or services over a fixed period through individual task or delivery orders. The base contract guarantees only a stated minimum; the real revenue comes from winning the orders placed under it.

How IDIQ contracts work
The agency competes and awards the base IDIQ — often to multiple vendors at once (a "multiple-award" IDIQ or MAC) — establishing scope, ceiling value, ordering period, and pricing structure. It then issues task orders (services) or delivery orders (goods) as needs arise during the ordering period.
On multiple-award vehicles, holders compete again at the task-order level under streamlined "fair opportunity" rules. Winning the base contract is a hunting licence, not a paycheque: vehicle holders that never bid task orders earn only the contract minimum.
Why agencies and vendors use them
Agencies like IDIQs because each task order avoids a full open competition — requirements that recur unpredictably get filled in weeks instead of months. Large programs such as GSA Schedules and GWACs (government-wide acquisition contracts) apply the same ordering logic across many agencies.
For vendors, a seat on the right vehicle means a smaller competitive field and faster awards for years. The trade-off is the up-front cost of winning the seat and the ongoing cost of monitoring and bidding task orders.
The Canadian counterparts
Canada achieves the same effect with standing offers (pre-priced, ordered by call-up) and supply arrangements (pre-qualified pool, priced per requirement). The IDIQ "requirements contract" pattern — guaranteed minimum, ordering ceiling, repeated orders — maps closely onto those vehicles.
| IDIQ (US) | Standing offer (Canada) | |
|---|---|---|
| Orders placed via | Task / delivery orders | Call-ups |
| Guaranteed volume | Stated contract minimum only | None |
| Pricing | Set or structured at base award | Fixed in advance |
| Multiple holders? | Often (multiple-award IDIQ) | Often |
Frequently asked questions
- Does winning an IDIQ guarantee revenue?
- Only the stated contract minimum, which is often nominal. Meaningful revenue depends on competing for and winning task orders issued under the vehicle.
- What is a task order?
- An individual order for services placed against an existing IDIQ contract (delivery orders are the goods equivalent). Each order defines its own scope, schedule, and price within the base contract's terms.
- Can I bid task orders without holding the IDIQ?
- No. Task orders are competed only among the vehicle's holders. If a market you serve runs through an IDIQ or GWAC, getting on the vehicle at its next on-ramp is the prerequisite.
