An Indefinite Delivery Contract (IDC) is a vehicle that has been awarded to one or more entities to facilitate the delivery of supply and service orders.
There are three types of Indefinite Delivery Contracts (IDC):
Definite Quantity Contract provides for delivery of a definite quantity of supplies or services for a fixed period, with deliveries to be scheduled at designated locations upon order.
Requirements Contract provides for filling all purchase requirements of designated government activities for supplies or services during a specified contract period, with deliveries to be scheduled by placing orders with the entity.
Indefinite Quantity Contract provides for an indefinite quantity, within stated limits, of specific supplies or services to be furnished during a fixed period with deliveries to be scheduled by placing orders with the entity. The contract shall require the Government to order and the entity to furnish at least a stated minimum quantity of supplies or services and, if ordered, the entity to furnish any additional quantities not to exceed a stated maximum.
Indefinite Quantity Contracts are sometimes referred to as Task Order and Delivery Order Contracts.
A Task Order Contract means a contract for services that does not procure or specify a firm quantity of services (other than a minimum or maximum quantity) and that provides for issuance of orders for the performance of tasks during the period of the contract.
A Delivery Order Contract means a contract for supplies that does not procure or specify a firm quantity of supplies (other than a minimum or maximum quantity) and that provides for the issuance of orders for the delivery of supplies during the period of the contract.
