What is the IDIQ agreement?

IDIQ is an acronym for a type of contract particularly suited for the government. These contracts frequently used by the USA, as the name implies, is a type of contract used to buy supplies and services, when a delivery time or quantity of goods is not fixed. These can be useful in two situations.

First, when one party is required to provide supplies or services indefinitely over a “predetermined period,” usually not exceeding 5 years.

Second, when one party is required to provide supplies or services of a “predetermined quantity” over a period, generally being of 5 years.

It acts as an umbrella/main contract for various orders issued thereunder. IDIQs allow the government contracting agency to “down select” multiple entities, this results in the contracting agency receiving bids from the pool of awardees for each follow-up task order, Theoretically, this provides them with the greatest value, convenience, and service possible. It also streamlines the process for issuing, awarding, and executing task orders.

This article aims to cover every aspect of an IDIQ contract for its better understanding, beginning with what it is, whom it is intended for, its applications, benefits and drawbacks, and concluding with all of the essential clauses that an effective IDIQ contract must have.

What does IDIQ refer to?

Although the word indefinite in Indefinite delivery/indefinite-quantity (IDIQ) may appear daunting, minimum and maximum quantity limits are defined, either by quantity or value. 

It is a type of procurement contract entered between a government agency and a private/ public industry when they cannot predetermine the precise quantity or exact time when the product or services would be needed keeping in mind its other benefits which are further enumerated below.  

Types of IDIQ contract

IDIQ contract can also be referred to as a work order contract and classified accordingly with respect to the nature of work for which it is employed including the following:

  • Delivery order: These IDIQs are for supplies/goods procurement. For example, the IT ministry entered into an IDIQ contract to procure IT infrastructure. 
  • Task order: These IDIQs are primarily based on ‘services.’ For example, a contract to provide Mail and General Support Services for a government department. 
  • Job order: These are IDIQ contracts for ‘construction services,’ with work orders determining performance and delivery schedules (can include task, and delivery order). For example, for construction of a road, bridge or any infrastructure.

Further, these can be classified based on terms which it includes which are as following:

  • Definite quantity contract: These contracts require the delivery of a certain quantity of specific supplies or services for a specific period of time, with deliveries or performance scheduled at locations decided by each task order. This contract may be used when the supplies or services are either already available or will be at a short notice. An example: When this would be useful is, to procure a definite quantity of vehicles over a period of time and not be delivered at one particular location.  
  • Indefinite quantity contract: This contract provides for an indefinite quantity of supplies or services over a set period, within the defined minimum and maximum limits. directives are imposed by the government based on needs. Quantity limits can be expressed in terms of the number of units or their monetary values. For example, when a government entity purchases machinery, which demands a regular supply of spare parts or servicing for optimum operation, here the exact quantity may not be calculated along with a time period rather than the exact time when it would be required, in such cases a definite quantity contract will be appropriate.
  • Requirements contract: It provides for the fulfilment of all procurement requirements of designated government activities for supplies or services throughout a contract period, with deliveries to be determined by the placing of orders with the contractor. There are no minimum and maximum limits specified instead the buyer’s promise to buy/perform the contract’s subject matter exclusively from the contractor is a crucial element of a requirements contract. In the above-stated example, if altering the terms, the government cannot determine the minimum and maximum quantity to the contractor over a specified time period instead promises to procure all the spare part and servicing needed exclusively from the contractor it would demand a requirement contract.

IDIQs can also be classified according to the number of work orders issued for a project/ task. Example; multiple work order contracts and single work order contracts. While In the former, the contracting entity grants to two or more contractors for similar goods or services from a single contract, if awarded to a single supplier may be unrealistic or may fail to meet the overall specifications.

Common applications

These contracts are offered when the government cannot determine the exact quantity or exact time for a recurring need of supplies and services. For flexible working, this contract is preferred for varied tasks including construction projects, IT system, research and development, design and architecture, advisory and assistance services, defence, and public transportation. The US government relies on these contracts even while responding during and post-natural calamities. 

Pricing under IDIQ

In an IDIQ contract, prices are often not pre-established. Accordingly, although contractors may offer a price package at the primary stage of awarding, they may be required to resubmit price proposals before the government issuing each task order. Task order pricing allows the government to take advantage of on-the-spot pricing and also permits the contractor to tailor a unique package to each agency’s procurement needs under the main contract.

Important Clauses in an IDIQ contract

The clauses of each IDIQ contract vary according to the type of IDIQ as discussed hereinabove while following the general clauses which should be included in a contract:

Solicitation and award

This clause includes the work or purpose for which the parties are entering into the contract in detail. Encompassing all the aspects of the agreement mentioning; general requirements/project scope:

  • Clarify the processes and selection criteria that will be used to ensure that each order is given a reasonable chance when multiple awards are made. 
  • Identify who may place orders and provide the contact details for the Task-order and Delivery-order Ombudsman. 
  • Specify whether or not orders can be placed orally.
  • Performance requirements/standards, measurement and verification, quality control, maintenance and response time, and any other sub-clause as per the nature of work.
  • Specify the overall minimum and maximum guarantee amounts to be ordered, when multiple IDIQ contracts are awarded from a single contract, each contract must contain a declaration about the contract’s minimum and maximum quantities of supplies or services. The sum for each contract minimum is specific to each contract and must be expressed as such; however, the amount for the maximum quantity may be expressed individually rather than for each contract award.

Minimum and maximum ceiling guarantee clause

This clause specifies the guaranteed minimum quantity to be ordered, which must be greater than a nominal quantity but not greater than the sum the government is reasonably likely to order. Setting it too low puts contractors at risk, which may lead to higher contract costs and/or a reduction in the number of contractors willing to make a bid. Also puts a ceiling to the maximum limits which may be based upon sound consideration.


  1. Maximum: The maximum contract ceiling value of all task orders in this master contract awarded is established at $15 Billion dollars.
  2. Minimum: The minimum guaranteed award amount for this IDIQ contract is $ 1 Billion and $2,500 dollars per task order for the full term of the Master Contract.
  3. The Government is under no obligation to give Task Orders (TO) to the Contractor in excess of the amount stated in this clause’s paragraph (b). 

Deliveries or performance

In this clause, the base period of performance of the agreement shall be included, can also include terms and conditions relating to a performance period of task orders issued thereunder, and relating to place of performance.


Period of performance

This master indefinite-delivery/indefinite-quantity (IDIQ) contract will have a base period of performance of five years and two choice periods of three years each, anticipated as follows:

Base Period of Performance:                                                          5/10/2018 – 5/10/2023

Place of performance

  1. Unless otherwise stated on the TO, performance will take place at the agency’s facility.
  1. The agency deliverables requirements will be specified in each TO.

Contract administration

this includes information regarding point of contact for this IDIQ, terms regarding issuing task orders, invoice instruction and payment schedule, and other technical directions.


Master IDIQ contract administration 

Administration of this master IDIQ contract shall be accomplished by________________ following individuals are responsible for administration of the same:

  1. Contracting officer: (include name, mail ID and other contact information)
  2. Contracting specialist: (include name, mail ID and other contact information)
  3. Contracting officer representative: (include name, mail ID and other contact information)

  2. The TOs awarded under this master IDIQ contract are fixed-price contracts.
  3. If the agency agrees in advance, changes to satisfy the TO’s design or performance specifications would come at no extra cost to the agency.
  4. The department can discuss any increases in contractor costs as a result of agency changes to the TO specifications.

The contractor must send invoices in compliance with the instructions in each TO given under this master IDIQ contract. The structure of the invoice, the content, any necessary attachments or enclosures, submission and addressing instructions, and so on will differ depending on the ordering agency.

Indefinite quantity

This provision states that this is an indefinite-quantity contract for the specified supplies or services and that it will be in force for the specified period. The amounts of supplies and services included in the Schedule are estimates only, and this contract does not purchase them.


  1. This is an indefinite-quantity contract for the supplies of services specified hereinabove in the Contract, and effective for the period stated in the schedule above. The number of services mentioned in the schedule is just an estimation and are not purchased by this contract.
  2. Deliveries and performance of the services shall be done only as authorised by the order clause hereinabove. The Government agency shall order at least the quantity as enumerated in the schedule as “minimum”.
  3. The contract shall govern the rights of the contractor’s and that of the government agencies.        

Price escalation clause

Since these contracts are usually for long periods there may arise factors beyond the control of either party affecting the value that has been determined. This clause allows modification to cover unexpected costs. This clause is usually included in Job orders (construction services). Further inclusion of this clause depends upon the nature of work and the type of contract.


Pricing shall remain the same throughout the base period of the Contract. The contractor may negotiate pricing for subsequent extension terms after the base period. The contractor shall submit in writing any proposed increase in pricing to CO for consideration at least 8 weeks prior to the expiration of the Contract. A contractor must provide relevant documentation in support of the request. Price increases accepted by CO will remain the same for the entirety of the extended term.

Merits of IDIQs

  1. Flexible: When requirements are unclear, IDIQ contracts offer flexibility and can extend to satisfy those needs without requiring contract alteration or repurchasing while limiting government liability to the minimum.
  2. Contract Integration: IDIQ can be used to merge many small contracts into one larger contract, which further simplifies the communication process.
  3. Open Contract: IDIQ shortens the time between project need and fulfilment, provides established sources for emergency actions.
  4. The fair opportunity enables the selection of best-of-breed solutions.
  5. Another benefit is that contracts can be awarded to a single company or a group of companies without having to go through the competitive bidding process that other forms of contracting to require. Not only can a contract be awarded multiple times (to two or more companies), but the contracted services or equipment can be delivered to several government departments or a single entity, depending on the contract’s wording.

Demerits of IDIQs

There are 2 principal disadvantages of this contracting method, regardless of the model used:

  1. The first limitation in this method is most visible at the state level, and it is due to certain agencies’ and contractors’ lack of expertise and experience with IDIQ contracts.
  2. Due to the pricing strategy model of this contract as discussed above, it limits the contracting agency from determining the Guaranteed Maximum Price (GMP) for the entire contract which provides them with increased control over product budgets. 

IDIQ Contracting v. Blanket Purchase Agreement

An IDIQ contract can appear to be identical to a Blanket Purchase Agreement (BPA) at first glance, but they are not. A fixed amount of time or quantity is focused on an IDIQ contract. while BPA is based on a set budget. In an IDIQ contract, minimums and maximums limits are specified, and delivery may be on-demand, all within the contract’s terms. A BPA, on the other hand, is motivated by a defined monetary sum rather than a specific number of services or units provided throughout the contract. The contract in BPA will come to an end after the budget money is spent.


IDIQ contracts aim to streamline the lengthy, rigid and complicated process of government contracting. These contracts must be carefully drafted to include all facets of the project/task. To prevent possible mishaps, the contractors should analyse the demand and their capacity before agreeing.
