Indefinite delivery, indefinite quantity contracts provide for an indefinite quantity of services for a fixed time. They are used when GSA can’t determine, above a specified minimum, the precise quantities of supplies or services that the government will require during the contract period. IDIQs help streamline the contract process and speed service delivery.
IDIQ contracts are most often used for service contracts and architect-engineering services. Awards are usually for base years and option years. The government places delivery orders (for supplies) or task orders (for services) against a basic contract for individual requirements. Minimum and maximum quantity limits are specified in the basic contract as either number of units (for supplies) or as dollar values (for services).
