Understanding Bid Bonds vs Performance Bonds: A Comprehensive Guide

Dec 30, 2023 By Susan Kelly

If you want to ensure contractors complete the work for the agreed-upon price, you need bid bonds. Public construction contracts often call for these bonds as a form of client financial and legal security. Customers would not know whether a contractor could successfully finish a project if bid bonds weren't available. For instance, if the contractor doesn't have enough money, they might face money problems while the project is underway. Bid bonds also help weed out fraudulent bids, making choosing reliable contractors easier.

Requirements for Bid Bonds

Project owners often request a security deposit ranging from 5% to 10% of the tender amount. However, projects receiving federal funding can request deposits of up to 20% of the bid value. The total bid value, the location of the project, and certain contractual conditions determine the cost of the bond. For example, a $50,000 bid bond form is required if a contractor submits a bid of $250,000 for a roofing project at a school. This requirement is a critical component of the proposal for those seeking federal contracts.

Composing a Bid Bond

A bid bond is a formal assurance a third-party guarantor provides and is presented to a client or project owner. This bond confirms that the contractor possesses the necessary funding to execute the project. Commonly, contractors present bid bonds as monetary deposits when submitting a tendered bid. A contractor acquires a bid bond form from a surety. This surety conducts thorough financial and background investigations on the contractor before sanctioning the bond.

Multiple criteria influence the decision to grant a bid bond to a contractor. These criteria encompass the company's credit record and its duration of operation in its respective field. Additionally, financial reports are scrutinized to assess the company's overall financial condition. The purpose of a bid bond vs performance bond is multifold. The project owner needs this document to ensure the contractor's financial stability and commitment. The bond protects the project owner if the contractor fails to meet bid obligations. This system screens out unqualified bidders and ensures only financially stable, experienced contractors bid.

Contractors should carefully evaluate their financial capacity and project preparedness before applying for bid bonds. Through self-reflection, project planning and execution can be improved. Bid bonds benefit project owners and contractors by establishing a more consistent and trustworthy financial environment.

Key Participants in a Surety Bond

The principal—usually the contractor—the obligee—the project owner—and the surety—the financial backer—make up a surety bond. This bond is crucial in construction. By providing the obligee with a financial guarantee, the surety ensures that the contractor will adhere to the bond's specified conditions. This financial backing is vital in construction projects, providing security and trust in the contractual relationship.

The obligee, usually the project owner, is the individual or organization that engages the contractor and necessitates the bond. This entity is responsible for setting the specific terms and conditions of the bond. Should the contractor not fulfill their obligations or breach the contract, the obligee has the right to claim against the bond. The principal, generally the contractor, is responsible for acquiring the bond. This bid bond vs performance bond party carries the obligation to fulfill the contract's stipulations. Failure to meet these requirements subjects the contractor to liabilities specified in the bond and the contract.

Surety companies play a crucial role in this triad. They assess the financial reliability of the principal, which in this case is the contractor or builder. Based on this evaluation, they determine a premium, reflecting the assessed risk of a potential failure or breach. This premium is an essential aspect of the bond, as it quantifies the level of risk involved in the project and the contractor's reliability.

Bid vs. Performance Bonds

A bid bond becomes a performance bond when a proposal is accepted, and the contractor begins work. This change protects the project owner throughout the contract. Performance bonds protect clients from contractor errors based on contractual terms. The project owner can claim against the performance bond if the contractor's work is substandard. This bond provides financial protection for repairs or rework.

In contrast, a bid bond example is crucial during the initial contractor selection process. It assures the project owner that the contractor will follow the bid price and terms. The bid bond guarantees that the contractor will complete the project and post a performance bond if chosen. If a contractor wins the bid but doesn't sign the contract or start the performance bond process, the bid bond is crucial. This decision can cost the project owner more because they must choose the next lowest bidder. So, the bid bond example protects the client financially by allowing them to claim compensation for extra costs caused by the original contractor's violation.

Not Meeting Obligations

Both the contractor and the surety company are liable for bid bond violations. Joint and several liability protects the project owner if the contractor fails to meet requirements. The project owner faces a dilemma when a contractor is chosen based on a bid but fails to execute the contract or provide the performance bond. The client must often choose the second-lowest bidder, incurring extra costs. These situations make bid bonds crucial financial tools. An indemnity bond protects the client from financial losses if a winning bidder doesn't deliver.

The bid bond affects bidding as well as financial security. Clients prefer the lowest bidder because it reduces project costs. Thus, the bid bond example encourages contractors to submit competitive but realistic bids, knowing that failure to comply can result in significant financial penalties. Performance bonds ensure work quality and timeliness. The performance bond protects the client financially if the contractor fails to meet standards or deadlines. This bond protects the client if the contractor fails to complete the agreed-upon project.


Bid bonds protect project owners from unreliable contractors in the construction industry. They verify contractors' finances and commitment to project completion. Bid bonds eliminate unqualified bidders and ensure only experienced and financially stable contractors compete by requiring a 5-20% deposit of the bid value.

These bonds become performance bonds upon the start of the project, protecting the owner from substandard work and non-compliance. Project owners and reputable contractors benefit from bid bonds' more reliable bidding process and secure financial environment in construction contracts.
