Bid Bonds

If you're bidding on public construction projects — or private jobs with bonding requirements — a bid bond is usually the first thing you need. It's the document that tells the project owner you're financially qualified, your bid is real, and you're prepared to follow through if you win the work.

Without a bid bond, you don't get to the table. It's that simple.

At Grit Insurance Group, we help contractors secure bid bonds quickly so they don't miss deadlines, and we help them build the surety relationships that make future bonds easier to obtain. Whether this is your first bid bond or your fiftieth, our team understands the urgency and the process.

 What Is a Bid Bond?

A bid bond is a three-party agreement between the contractor (principal), the project owner (obligee), and the surety company. It serves as a guarantee that the contractor submitting a bid will honor the terms of that bid if selected for the project.

Specifically, a bid bond guarantees three things. First, that your bid was submitted in good faith and reflects your genuine intent to perform the work at the price you quoted. Second, that if you're awarded the contract, you'll actually sign it. Third, that you'll provide the required performance and payment bonds once the contract is executed.

If you fail on any of those commitments — you walk away from the job, refuse to sign the contract, or can't provide the required follow-up bonds — the surety may be required to compensate the project owner. That compensation is typically the difference between your bid and the next lowest qualified bidder, up to the penal sum of the bid bond.

Why Do Project Owners Require Bid Bonds? 

Project owners use bid bonds as a filter. They need to know that every contractor submitting a bid has the financial backing and the intent to actually do the work. Without that guarantee, the bidding process breaks down — owners waste time evaluating bids from contractors who can't follow through, and project timelines suffer when a winning bidder drops out.

On federal projects, bid bonds are required by the Miller Act for any construction contract over $150,000. Most state and municipal governments have similar requirements under their own bonding statutes. Many private owners — particularly on larger commercial and industrial projects — also require bid bonds as part of their prequalification process.

The bid bond doesn't just protect the owner. It also levels the playing field for qualified contractors. When every bidder has to put up a bond, it weeds out companies that aren't financially prepared to take on the work. That means you're competing against other serious contractors, not against lowball bids from companies that can't deliver

 How Much Does a Bid Bond Cost? 

In most cases, bid bonds cost nothing upfront. Sureties typically issue bid bonds at no charge to the contractor as long as you have an established relationship with the surety or qualify through the underwriting process. The surety views the bid bond as the entry point to issuing the performance and payment bonds — which is where the premium is collected — so they don't usually charge separately for the bid bond itself.

That said, there are situations where a surety may charge a small fee for a bid bond. This typically happens when the contractor doesn't have an existing bond program, when the project is unusually large relative to the contractor's capacity, or when the contractor's financial profile requires additional underwriting work.

The real cost of a bid bond isn't the premium — it's the preparation. Having your financials in order, your credit in good shape, and your surety relationship established before you need a bond is what makes the process fast and affordable. Contractors who wait until the last minute to find a surety often struggle with delays, higher costs, or outright denials.

 How to Get a Bid Bond  

The process depends on where you are as a contractor.

If you're a smaller or emerging contractor and you need a bid bond for a project under $1 million, we can often get you approved on a simple one-page credit-based application. This is a straightforward process that relies primarily on your personal credit score and basic business information. Turnaround can be as fast as 24 to 48 hours once we have your information.

For larger projects or contractors seeking higher bond limits, the process involves more detailed underwriting. Your surety will want to review your company financial statements (preferably CPA-prepared), personal financial statements for all owners with significant ownership, your work-in-progress schedule, a list of completed projects, bank references, and your resume of experience. The more complete and organized your submission, the faster the process moves.

If you already have a bond program in place with an established surety, getting a bid bond for a new project is typically quick — often same-day — because the underwriting has already been done and your capacity is pre-approved.

Regardless of your situation, having a bond agent who knows surety and can communicate effectively with underwriters makes a real difference. A good agent doesn't just submit paperwork. They position your company in the best possible light and advocate on your behalf when questions come up

What Happens If You Win the Bid?   

When you're awarded the project, the bid bond has done its job. You'll sign the contract and your surety will issue the performance bond and payment bond required to move forward. The bid bond itself typically expires at that point.

The performance bond guarantees you'll complete the work according to the contract. The payment bond guarantees you'll pay your subcontractors and suppliers. These bonds are where the surety premium is collected — usually calculated as a percentage of the contract value, based on your financial profile and the surety's assessment of risk.

If your surety relationship and financials are solid, this transition from bid bond to performance and payment bonds is seamless. If there are issues — financial weaknesses, incomplete documentation, or a project that stretches beyond your approved capacity — this is where problems surface. That's why building your bonding capacity proactively, rather than reacting project by project, matters so much

Common Reasons Bid Bonds Get Denied    

Not every contractor who applies for a bid bond gets approved. Sureties are underwriting your ability to perform on the project, so they take a careful look at your financial health and track record. The most common reasons contractors run into trouble include poor personal credit, which is often the first thing a surety checks on smaller bonds. Incomplete or outdated financial statements create delays and signal to underwriters that the contractor may not have a firm handle on their finances. Overbidding relative to capacity is another common issue — if the project you're bidding is significantly larger than anything you've completed before, the surety may not be comfortable extending the bond. Lack of experience in the project type, insufficient working capital, and unresolved issues on previous bonded projects can also lead to a decline.

If you've been turned down for a bid bond, it doesn't necessarily mean you're unbondable. It often means something in your financial presentation needs to be addressed. Our team can review your situation, identify what's holding you back, and help you build a plan to qualify.
