Quick Answer: What Are Task Order and IDIQ Contracts?

IDIQ (Indefinite Delivery/Indefinite Quantity) contracts are framework agreements that allow government agencies to order products or services as needed over a set period. Once you win an IDIQ contract, you compete for individual task orders issued under that contract, providing a steady pipeline of opportunities without repeatedly competing for the base contract.

What Are IDIQ Contracts?

Indefinite Delivery/Indefinite Quantity (IDIQ) contracts are a type of contract vehicle that provides for an indefinite quantity of services or supplies during a fixed period of time. Rather than specifying exact quantities upfront, these contracts establish minimum and maximum quantities and allow the government to order what they need when they need it.

IDIQ contracts have become the dominant procurement method for many federal agencies because they offer flexibility, reduced procurement time, and the ability to quickly respond to changing requirements. For contractors, winning an IDIQ position provides ongoing access to government work.

Key Characteristics of IDIQ Contracts

  • Indefinite Quantity: No fixed amount of work guaranteed beyond minimum
  • Ordering Period: Set timeframe (typically 5 years with options)
  • Multiple Award: Usually awarded to multiple contractors
  • Fair Opportunity: Contract holders compete for task orders
  • Ceiling Value: Maximum contract value over the ordering period

Types of IDIQ Contracts

IDIQ contracts come in several forms, each with different characteristics and uses. Understanding these variations helps you identify the right opportunities.

Single Award IDIQ

  • One contractor holds the contract
  • No task order competition
  • Highly specialized requirements
  • All work goes to winner

Multiple Award IDIQ (MAC)

  • Multiple contractors share the contract
  • Task order competition required
  • Most common IDIQ type
  • Promotes ongoing competition

Frequently Asked Questions

What is the minimum guarantee on an IDIQ contract?

IDIQ contracts must have a minimum guarantee, which is the minimum amount of work the government must order. This is often a nominal amount (such as $2,500) but can be higher. The minimum guarantee ensures the contract has consideration and is legally binding.

Can I protest a task order award?

Yes, task order protests are allowed for orders exceeding $25 million (DoD, NASA, Coast Guard) or $10 million (civilian agencies). Protests are filed with GAO and must be submitted within 10 days of award notification or knowledge of the grounds for protest.

How do I find IDIQ opportunities to bid on?

IDIQ contract opportunities are posted on SAM.gov like other federal contracts. Look for solicitations that specifically indicate IDIQ, indefinite delivery, or multiple award contracts. Agency forecasts and industry events also announce upcoming IDIQ competitions.

What happens when an IDIQ contract expires?

When the ordering period ends, no new task orders can be issued, but existing task orders continue until completion. Agencies typically re-compete the contract vehicle before expiration to ensure continuity of services. Contractors should plan for transition.

Can small businesses compete on large IDIQ vehicles?

Yes, many IDIQ vehicles have small business pools or tracks. Additionally, small business set-asides at the task order level are common on multiple award contracts. Some vehicles like 8(a) STARS III are exclusively for 8(a) firms.
