IDIQ

In U.S. Federal government contracting, IDIQ is an abbreviation of the term indefinite delivery/indefinite quantity. This is a type of contract that provides for an indefinite quantity of supplies or services during a fixed period of time. The legal origin of IDIQ contracts is the Federal Acquisition Regulation (FAR) section 16.504(a). IDIQs are also sometimes called "Task Orders" or "Delivery Order Contracts." IDIQ contracts are a subtype of Indefinite Delivery Contract (IDC), which is a "vehicle that has been awarded to one or more vendors to facilitate the delivery of supply and service orders."
