What it is
A bid bond is a guarantee that comes with a contractor's bid on a project. It generally tells the project owner that the contractor is serious, qualified, and, if selected, will be willing to sign the contract and provide any other required bonds at the bid price.
A performance bond comes later. It is a construction bond that generally protects the project owner if the contractor does not complete the work according to the contract terms. It is typically tied to the signed contract rather than to the bidding process.
In both cases, three parties are involved: the contractor (the principal), the project owner (the obligee), and the surety company that stands behind the bond. The two bonds answer different questions: a bid bond asks, 'Will you follow through on your bid?' A performance bond asks, 'Will you finish the job as promised?'
How it’s traditionally been approached
Traditionally, public projects and many larger private projects have asked bidders to submit a bid bond with their proposal. If the winning bidder backs out or cannot enter the contract, the bond may provide a way for the owner to address certain related losses, subject to the bond's terms.
Once a contract is awarded, the owner may then require a performance bond, often alongside a payment bond. The performance bond is generally issued after the contract is signed and remains connected to the project through its completion, depending on its terms.
Requirements for both bonds vary by state, agency, and project. Some owners require both, some require only one, and some require neither. The bid documents usually spell out what is needed, so reading them closely is a long-standing first step.
How the right surety agent may help
A surety agent who works with contractors may help you understand how a bid bond and a performance bond connect. Many contractors find it useful to talk through the bonds early, since the bid bond often leads into the performance bond if a project is awarded to them.
A first conversation is generally a chance to share your business background, the kinds of projects you pursue, and the bid requirements you are looking at. An agent may explain what information surety companies often look at, such as financial records and experience, and how that may relate to the bonding you need. Nothing about approval or capacity can be promised in advance.
Good questions to ask include: Which bonds does this project require? How does the bid bond relate to the performance bond if I win? What documents should I prepare? How early should I reach out before a bid deadline? Also confirm the specifics with the project owner or contracting agency.
The bigger picture
Bidding on work can be stressful, especially when paperwork and deadlines pile up alongside running a crew and managing cash flow. Knowing what each bond does and when it is needed may help you plan ahead and feel steadier about taking on new opportunities.
Financial decisions in construction touch more than the business; they often affect family, employees, and peace of mind. Taking time to ask questions and understand your options, without rushing, is a reasonable way to look after both your company and yourself.

Frequently asked questions
What is the main difference between a bid bond and a performance bond?
A bid bond supports your bid and generally shows you will sign the contract if selected. A performance bond supports the work itself and generally protects the owner if the contractor does not complete the project per the contract. One applies at the bidding stage, the other after award.
Do I need both a bid bond and a performance bond?
It depends on the project. Some owners require both, some only one, and some neither. The bid documents and the contracting agency set the requirements, and a licensed surety agent can help you read them.
Which comes first, a bid bond or a performance bond?
The bid bond typically comes first because it is submitted with the bid. If you are awarded the contract, the owner may then ask for a performance bond, often before work begins.
Does winning a bid mean I automatically get a performance bond?
No. Winning a bid does not guarantee a performance bond will be issued. The surety company generally reviews your situation separately, which is one reason many contractors talk with an agent before they bid.
Who is protected by a bid bond vs a performance bond?
In both cases, the project owner, called the obligee, is the party the bond is designed to protect. The contractor is the principal who must meet the obligations, and the surety stands behind the bond according to its terms.
How can a surety agent help with a bid bond vs performance bond question?
A surety agent may explain what each construction bond does, review what your project requires, and discuss what documents to prepare. They cannot promise approval or a specific bond capacity, so always confirm details with the project owner or agency.
