An indeterminate delivery contract is an acquisition tool that has grown considerably in popularity over the past decade. There are three types of indeterminate supply contracts: set quantity, indeterminate quantity and needs contracts. All three are used to purchase supplies and/or services when the exact dates and/or exact quantities of future deliveries are not known at the time of contracting. Supply contracts and indeterminate contracts are also referred to as supply contracts or “operating contracts.” They often hear and read the terms “mission contract” and “task issuance” in discussions and documents related to GSA calendars. Even if FAR 8.4 provides specific authorities for GSA plan contracts that follow the specific provisions of FAR 16.5 for order contracts or indeterminate contracts, understanding these vehicles will help to better understand the operation of a GSA calendar. With an IDIQ vehicle, buyers give orders for individual needs, and quantity limits can be indicated in number of units or dollars. The contract must require the purchaser to order and contracting to provide at least a minimum amount of declared supplies or services. A contract must indicate the implementation period, including the number of option periods, and the total and maximum amount of supplies or services the government will purchase under the contract. A contract requires a contractor or contractor to provide services or products as ordered. There is no set frequency for commands.

This means that the contractor must wait until there is a need from the state buyer. Contract contracts allow public obligations to be kept to a minimum level and sent directly to users of products or services. They also allow for great flexibility in the planning of quantities and deliveries and the ability of buyers to order supplies and services only if specific requirements are met for them. Perhaps most importantly, contract contracts limit the government`s commitment to the minimum amount set out in the contract. Contract contracts are used by buyers who are unable to determine in advance the exact amounts of supplies or services they need during the term of the contract, if they are not advised to set more than a minimum amount. As with IDIQs, there will be a list of requirements in the Work Statement (SOW). These requirements are agreed upon by both the public purchaser and the contractor and must be met as a contractual condition. An operating order adds additional needs and/or quantities to the order. The tasks are used in IDIQs (indeterminate delivery, indeterminate quantity). These are adaptable types of contracts that give a government authority or agency the flexibility to accept a contract if specific requirements or needs are not known.
