If you have bid on a government contract or a large private project and lost because you could not provide a surety bond, you are not alone. Bonding is the most common barrier between a qualified small contractor and their first public works project. The SBA Surety Bond Guarantee Program exists specifically to fix this problem. Most small contractors do not know it exists.
The three types of bonds contractors need
Bid bond: Submitted with your bid. It guarantees that if you win the contract, you will enter into the contract and provide the required performance and payment bonds. If you win and then back out, the surety pays the bid bond amount to the project owner. Bid bonds typically cover 5-10% of the contract value. They rarely require payment from the contractor: the surety issues them as part of your bonding relationship.
Performance bond: Issued after you win a contract. It guarantees you will complete the contract according to its terms. If you default, the surety either completes the project themselves, hires another contractor to finish, or pays the project owner the bond amount. Performance bonds typically cover 100% of the contract value.
Payment bond: Accompanies the performance bond on most public projects. It guarantees you will pay your subcontractors, suppliers, and laborers. Subcontractors have direct claims against your payment bond if you fail to pay them. Payment bonds also typically cover 100% of contract value.
Federal contracts above $150,000 require both performance and payment bonds under the Miller Act (40 U.S.C. §§ 3131-3134). Most state and local governments have similar "Little Miller Act" requirements, typically at lower thresholds. Private projects may also require bonding, especially for commercial construction financed by institutional lenders.
What surety companies are actually evaluating
Surety companies are not insurers in the traditional sense. They expect the contractor to perform, and they will pursue recovery from the contractor if the contractor defaults and the surety pays out. The bond is a credit product, not insurance.
That means surety underwriters are evaluating your ability to complete the contract without defaulting. Specifically:
Financial strength: Working capital, equity in the business, and liquidity. Surety companies look at your balance sheet, not just your income statement. A contractor doing $2 million in revenue but with no cash reserves and maxed-out credit lines is a worse bonding risk than one doing $500,000 with $100,000 in the bank.
Track record: Completed projects, on budget and on schedule. Your first bond is the hardest to get because you have no track record. Sureties want to see you have successfully completed projects of a comparable size.
Character and reputation: References from general contractors, subcontractors, and owners. Sureties do call references.
Work-in-progress: How many open contracts do you have and what is your capacity? A surety that bonds you for a $500,000 contract while you already have $1.5 million in incomplete work will want to know you have the capacity to manage all of it.
What bonding actually costs
Bond premiums are typically 1-3% of the contract value for contractors with established track records. First-time bonding candidates or contractors with limited financial history pay 2.5-4% or higher through specialty surety markets.
On a $200,000 contract, that is $4,000 to $8,000 in bond premiums for performance and payment bonds combined. On a $500,000 contract, $10,000 to $20,000.
These are not loan payments. You pay the premium once, at bond issuance. If you complete the contract without issue, the bond expires and you pay nothing more.
Some surety companies charge separate premiums for the bid bond. Others include it with the performance/payment bond package.
The SBA Surety Bond Guarantee Program
The SBA guarantees surety bonds for small contractors who cannot qualify in the conventional surety market. The program covers four bond types: bid, performance, payment, and ancillary bonds.
Coverage: The SBA guarantees 90% of the surety's loss on bonds for businesses owned by socially and economically disadvantaged individuals (including 8(a) participants), and 80% of the loss for other eligible small businesses. This guarantee lets participating sureties approve contractors they would otherwise decline.
Contract size limits: The standard program covers contracts up to $10 million. There is a pilot program for contracts up to $6.5 million that uses a simplified approval process.
Eligibility: You must be a small business under SBA size standards for your NAICS code, meet SBA's character standards (no criminal history that would indicate financial unreliability), and have the technical ability to perform the contract. The SBA does not require you to have prior bonding history.
Cost: Contractors in the SBA program pay a small fee to the SBA on top of the bond premium. The SBA fee is 0.729% of the contract price as of 2024. On a $200,000 contract, that is about $1,458.
To use the program, you work with a surety agent or company that participates in the SBA Bond Guarantee Program. Not all surety agents are SBA-authorized. The SBA maintains a list of authorized sureties at sba.gov/surety-bond-guarantee.
How to build bonding capacity over time
The goal is to eventually qualify for bonding in the conventional market, without SBA support. Conventional bonding is faster, cheaper, and allows larger contract sizes.
Build your balance sheet. Surety companies look at your working capital ratio and net worth. Retain earnings in the business rather than drawing them all out. Aim for at least $1 of working capital for every $10 of projected bonded work.
Open a construction-specific bank account and maintain real records. Sureties do not trust contractors who commingle personal and business funds. Clean, separated financials signal professionalism.
Complete every contract you take. One default or dispute can eliminate your bondability for years. Start with smaller contracts and build a track record of clean completions.
Work with a surety agent, not a general insurance broker. Surety is a specialized line of business. A general property/casualty insurance broker who also happens to handle surety bonds will not have the relationships or market knowledge to place your first bond efficiently. Find an agent who specializes in contractor bonding.
Get certified in 8(a) or another SBA program. 8(a) status qualifies you for the 90% SBA guarantee rather than the 80% guarantee, making it easier for sureties to take you on.
Steps to get your first bond
- Know what you need before you need it. Read every bond requirement in the invitation for bid (IFB) or request for proposal (RFP) before you bid. Requirements vary by project. Some require the bond at bid submission; others require it only after award.
- Find an SBA-authorized surety agent. Use the SBA's list at sba.gov/surety-bond-guarantee. Call two or three agents and explain your situation. Ask specifically about the SBA Bond Guarantee Program.
- Prepare your financial documents. Surety agents need: two to three years of business financial statements (balance sheet, income statement), personal financial statement, current business bank statements, list of completed projects with dollar amounts and references, work-in-progress schedule.
- Apply through the SBA's electronic platform (eSBG). Your surety agent handles this. You do not apply to the SBA directly.
- Get the bond before the deadline. This sounds obvious, but bid bonds have hard deadlines. Do not start this process two days before the bid is due.
- After you complete the project, document it. Get a letter from the project owner confirming satisfactory completion. This goes into your track record file for future bonding applications.
The SBA Surety Bond Guarantee Program is one of the most underused tools in small contractor finance. If bonding has been the wall between you and a government contract, it is worth a conversation with an SBA-authorized surety agent before you assume you do not qualify.
