IDIQ Contracts
An indefinite-delivery, indefinite-quantity contract lets an agency order an unknown quantity of work over a fixed period. IDIQs are the workhorse of federal contracting and where most competitive dollars actually land.
- Managed by
- Individual agencies
- Ceiling
- Varies by contract
- Scope
- Any recurring requirement with uncertain quantity or timing
- Period of performance
- Typically 5 to 10 years
Key takeaways
- Vehicle access is a market position, not a contract — task orders are where revenue happens.
- Read the ordering guide before bidding a task order; format and evaluation rules differ from open-market RFPs.
- Fair-opportunity task orders move fast, often with 10 to 15 day response windows.
- Track on-ramp windows well in advance; they open rarely and close quickly.
How work is ordered
After award, work is issued as task orders (services) or delivery orders (products). Multiple-award IDIQs require fair opportunity among holders; single-award IDIQs let the agency order directly.
Getting on the vehicle
You get on by winning the base IDIQ competition, which is a full proposal effort with technical, management, past performance, and price volumes. Missing the base competition usually means waiting years for the recompete.
Winning task orders
Treat the base award as a market-entry investment and budget separately for task order capture. Firms that win IDIQ seats and then under-resource task order bidding end up with impressive contract vehicles and no revenue.
