Small Businesses Guide to Navigating Government Contracts Types

Entering the realm of government contracting can be a lucrative venture for small businesses, but it comes with its own set of complexities. One of the first challenges entrepreneurs face is understanding the various types of government contracts available and determining which ones best suit their needs. In this guide, we’ll explore three common types of government contracts — (1) fixed-price contracts, (2) cost-reimbursement contracts, and (3) indefinite delivery/indefinite quantity (IDIQ) contracts—and discuss the pros and cons of each.

1. Fixed-Price Contracts

As the name suggests, fixed-price contracts involve a predetermined price for the goods or services to be provided. This type of contract is commonly used when the scope of work is well-defined, and the risks are minimal. Here are the pros and cons:

Definition: A firm-fixed-price (FFP) contract provides for a price that is not subject to any adjustment on the basis of the contractor’s cost experience in performing the contract.


  • Certainty: With a fixed-price contract, the contractor knows exactly how much they will be paid for their work, providing a sense of financial stability.
  • Incentive for Efficiency: Contractors are incentivized to complete the project within budget and on time, as any cost overruns come out of their own pocket.
  • Simple Administration: Fixed-price contracts typically involve less administrative burden than other contract types, making them appealing to small businesses with limited resources.


  • Risk of Underestimation: If the scope of work is not accurately defined or unforeseen circumstances arise, the contractor may bear the cost of any additional work required.
  • Limited Flexibility: Changes to the scope of work can be challenging to negotiate and may require formal contract modifications, potentially leading to delays and additional costs.
  • Higher Bidding Competition: Since fixed-price contracts offer a clear price point, competition among bidders can be fierce, making it challenging for small businesses to win contracts.

2. Cost-Reimbursement Contracts

Cost-reimbursement contracts involve the government reimbursing the contractor for allowable costs incurred during the performance of the contract, plus a fee. This type of contract is often used when the scope of work is uncertain or highly complex. Here are the pros and cons:

Definition: A cost-reimbursement contract is a contract where all allowable contractor expenses are covered to an agreed-upon limit and an additional payment for a profit.


  • Flexibility: Cost-reimbursement contracts allow for greater flexibility in adjusting the scope of work as needed, making them suitable for projects with evolving requirements.
  • Shared Risk: Since the government shares the risk of cost overruns with the contractor, small businesses may feel more comfortable pursuing opportunities with higher uncertainty.
  • Potential for Higher Profit: Contractors can earn a fee on top of the reimbursed costs, providing the opportunity for higher profit margins compared to fixed-price contracts.


  • Administrative Burden: Cost-reimbursement contracts typically require more extensive documentation and oversight to ensure that costs are reasonable, allowable, and allocable.
  • Lack of Incentive for Efficiency: Unlike fixed-price contracts, where contractors have a financial incentive to control costs, cost-reimbursement contracts may incentivize inefficiency if contractors are reimbursed for all allowable costs.
  • Audit Risk: Contractors may be subject to audits by the government to verify the legitimacy of costs claimed, which can be time-consuming and costly.

3. Indefinite Delivery/Indefinite Quantity (IDIQ) Contracts

IDIQ contracts provide for an indefinite quantity of goods or services to be delivered over a fixed period, often with a predetermined maximum value. This type of contract is commonly used for recurring requirements or when the exact quantity or timing of deliveries is uncertain. Here are the pros and cons:

Definition: An Indefinite Delivery/Indefinite Quantity (IDIQ) contract is a type of contract used by government agencies to procure goods or services when the exact quantity or timing of deliveries is uncertain.


  • Streamlined Procurement: IDIQ contracts streamline the procurement process by establishing pre-negotiated terms and conditions, allowing for faster acquisition of goods or services as needs arise.
  • Flexibility: IDIQ contracts offer flexibility in terms of quantity, delivery schedule, and pricing, making them suitable for projects with variable requirements.
  • Opportunity for Long-Term Relationships: Winning an IDIQ contract can lead to long-term relationships with government agencies, providing a stable source of revenue for small businesses.


  • Competition for Task Orders: Contractors must compete for individual task orders issued under the IDIQ contract, potentially facing competition from other contract holders.
  • Uncertain Work Volume: The volume of work under an IDIQ contract may vary over time, making it challenging for small businesses to predict revenue and resource allocation.
  • Compliance Requirements: Contractors must comply with the terms and conditions specified in the IDIQ contract, including reporting requirements and performance metrics, which can add administrative burden.

Other Types of Contracts

Small businesses participating in government contracts may also encounter Time and Material (T&M) contracts and Incentive contracts.

  • Time and Material (T&M) Contracts: Time and Material contracts involve payment based on the actual hours worked by the contractor’s personnel and the cost of materials used, with a predetermined hourly rate for labor and reimbursement for allowable material costs. While T&M contracts provide flexibility and transparency, they also present the risk of cost overruns and lack of incentives for efficiency.
  • Incentive contracts: offer a combination of fixed-price and cost-reimbursement elements, providing incentives for contractors to meet or exceed performance targets through rewards or penalties. While Incentive contracts can motivate contractors to achieve superior results, they also require careful negotiation of performance metrics and risk-sharing mechanisms to ensure alignment between the contractor’s objectives and the government’s goals.

In conclusion, each type of government contract—fixed-price, cost-reimbursement, and IDIQ—offers its own advantages and challenges for small businesses. By understanding the pros and cons of each contract type, entrepreneurs can make informed decisions when pursuing government contracting opportunities and develop strategies to mitigate risks and maximize opportunities for success.
