Type of contract that provides for an indefinite quantity of supplies or services during a fixed period of time. Under the Federal Acquisition Regulations (FAR) in 16.501(a), when a government program manager is unsure of the exact quantity of products or services needed to fulfill his or her agency’s needs, or the exact time at which these products or services will be necessary, an Indefinite Delivery/Indefinite Quantity (ID/IQ) contract provides the solution. Supplies or services are acquired through the issuance of individual delivery orders or individual task orders (i.e., Job Order Contracts). An ID/IQ contract is ideal for many government contracting officers because the tasks can be aligned in accordance with the agency’s available funding. Also known as job order contracting (JOC) to public entities.
