What Is Indefinite Delivery Indefinite Quantity?
An Indefinite Delivery Indefinite Quantity (IDIQ) contract is a government contract type that allows agencies to order an unspecified quantity of supplies or services during a fixed contract period, within stated minimum and maximum limits.
IDIQ contracts are used when agencies anticipate recurring needs but cannot predict precise volumes.
Key Characteristics
Provides flexibility when exact quantities cannot be determined in advance
Establishes a minimum and maximum ordering threshold
Orders are issued through task orders or delivery orders
Used for recurring or on-demand needs
Awarded for a defined performance period
How It Works in Government Contracting
An agency may award an IDIQ for IT support services and issue task orders only when support is needed, rather than contracting for a fixed amount upfront.
Where it appears: IDIQ contracts are awarded during the solicitation phase, with work executed later through individual task orders or delivery orders.
Who uses it: Federal agencies, state governments, and authorized contracting offices use IDIQ contracts. Contractors holding the contract compete for or receive orders under it.
Why it matters: It enables faster procurement while maintaining compliance and competition.
Regulatory Framework
IDIQ contracts are governed by the Federal Acquisition Regulation, specifically FAR Part 16.5. This section establishes requirements for minimum quantities, ordering procedures, and competition among contract holders.
Why IDIQ Matters for Contractors
Creates long-term access to government work opportunities
Requires readiness to scale resources up or down
Revenue is not guaranteed beyond the minimum order
Order-level competition can impact workload predictability
Compliance with ordering and performance requirements is critical
Common Misconceptions About IDIQ
Winning an IDIQ guarantees substantial work.
Only the stated minimum quantity is guaranteed. All additional work must be ordered and, in many cases, competed.
IDIQ contracts are noncompetitive after award.
On multiple-award IDIQs, task and delivery orders are typically competed among contract holders.
All IDIQ orders are automatically awarded to one contractor.
Many IDIQs are awarded to multiple contractors who then compete for individual orders.
