What it is
A bid bond is a three-party agreement tied to a construction bid. The contractor submitting the bid is the principal, the project owner or agency requesting it is the obligee, and the surety is the company that stands behind the bond.
Its general purpose is to give the project owner some assurance that a bidder will enter into the contract and provide any required follow-on bonds if the bid is accepted. If a selected bidder walks away, the bond may provide a way for the owner to seek certain losses, subject to its terms.
A bid bond is not insurance for the contractor, and it is not a prediction of who will win the work. Its terms, forms and whether one is required at all vary by state, agency and project, so the bid documents are always the first place to look.
How it’s traditionally been approached
Public projects have commonly asked bidders to include a bid bond with their proposal, and some private owners request them as well. The bid documents typically describe the form to use and how the bond amount is to be stated.
Traditionally, contractors have worked with a surety agent or broker who submits information about the business to a surety company. The surety generally looks at things like the contractor's experience, financial strength, work on hand and character before deciding whether to issue bonds.
Bid bonds are often connected to performance bonds and payment bonds. A bid bond supports the bidding stage, while a performance bond generally supports completion of the contract after award. Many contractors consider the whole bonding path early, rather than one bond at a time.
How the right surety agent may help
The right surety agent may help you make sense of the paperwork. They can explain what the bid documents are asking for, which bond form may be needed, and how the bid bond relates to later performance and payment bond requirements.
A first conversation is generally an information-gathering exchange. The agent may ask about your company history, project experience, financial statements, current backlog and the type of work you are bidding. Having these organized in advance may make the process smoother, though outcomes are never guaranteed.
Helpful questions to ask include: What does this project's bid package require? What does the surety usually review? How far ahead should I start before a bid deadline? What happens to the bid bond if I'm not selected, or if I am? Can you walk me through the indemnity agreement before I sign? Always confirm requirements with the project owner or contracting agency as well.
The bigger picture
Bidding on a project can carry real pressure. Deadlines, paperwork and the question of whether you'll be approved can weigh on your sleep, your focus and your sense of confidence, especially for smaller or growing contractors. Understanding the process ahead of time may ease some of that uncertainty.
Taking the time to learn how bonding works, and building a relationship with a surety agent before you need one in a hurry, may support steadier decisions and more peace of mind about your business finances.

Frequently asked questions
What is a bid bond in construction?
A bid bond is a surety bond submitted with a construction bid that helps assure the project owner the bidder will enter into the contract if selected. It involves three parties: the contractor, the project owner, and the surety. Specific terms depend on the project and the bond form used.
Why do project owners require bid bonds?
Owners may require them to help screen for serious, qualified bidders and to have some protection if the selected bidder does not proceed. Requirements differ by agency and project, so check the bid documents.
Is a bid bond the same as a performance bond?
No. A bid bond relates to the bidding stage, while a performance bond generally relates to completing the contract after it is awarded. They are often discussed together because a bid bond may reference the later bonds the winning bidder is expected to provide.
Who can provide a bid bond?
Bid bonds are issued by surety companies, usually through a licensed surety agent or broker. An independent agent may be able to explain which sureties may be a fit for your situation, though no approval is guaranteed.
What does a bid bond cost?
Cost varies and this page does not quote prices. Some situations and sureties handle bid bonds differently, so ask a licensed surety agent what applies to your circumstances and the project.
What happens if I win the bid but don't follow through?
The bid bond may allow the project owner to make a claim under its terms, and the contractor may be responsible to the surety through an indemnity agreement. The details depend on the bond form and agreement, so review them carefully with your agent and, if needed, a qualified attorney.
