Building an Underwriting File
The Better Your File, the Faster You Get Bonded and the Better Your Terms
When a surety company evaluates your bond application, they are not guessing. They are working from a specific set of documents that together tell the story of your business: who you are, how you manage money, what kind of work you do, and whether you can deliver on the projects you want to bond.
That collection of documents is called your underwriting file. Think of it as the surety's version of a loan application, except the surety is not lending you money. They are lending their financial guarantee that you will perform. The more complete and well-organized your file is, the faster the underwriting process moves and the more favorable your terms will be.
Many contractors lose time and opportunity because they submit incomplete information, provide documents in formats the surety cannot use, or wait until a bid deadline to start pulling things together. The contractors who consistently get bonded on time and at competitive rates are the ones who keep their underwriting file current, organized, and ready to go before they need it.
At Grit Insurance Group, building and maintaining a strong underwriting file is one of the first things we help contractors with. This page walks through every document a surety will look for and explains why each one matters.
Company Financial Statements
Your company's financial statements are the foundation of your underwriting file. They are the first thing the surety reviews and the single most important factor in determining your bonding capacity. Sureties want to see a balance sheet, income statement, and cash flow statement that demonstrate your company's financial health.
The level of CPA involvement matters significantly. For smaller bond programs, typically up to $500,000 in single job capacity, a surety may accept internally prepared or CPA-compiled statements. For programs above that level, most sureties require at least CPA-reviewed statements. For large programs, audited financials are the standard.
Sureties look for several specific things in your financial statements: positive working capital (current assets minus current liabilities), consistent profitability, adequate net worth relative to the size of projects you want to bond, healthy cash flow, and clean receivables. If your working capital is trending upward and your profitability is consistent, the surety has reason to extend more capacity. If your financials show losses, declining working capital, or high debt relative to equity, those are red flags that limit what the surety is willing to guarantee.
Submit your year-end financials within 90 to 120 days of your fiscal year end. Do not wait for the surety to ask.
Financial Strength and Bonding
Contractor Financial Statement Guide
Personal Financial Statements
Every individual who owns 10% or more of the contracting company will need to provide a personal financial statement. The surety requires this because most contract surety bonds include a personal indemnity agreement, meaning the owners are personally guaranteeing the surety's exposure.
Your personal financial statement should list all assets (real estate, investments, retirement accounts, vehicles, cash) and all liabilities (mortgages, loans, credit card balances). The surety is looking at your personal net worth and your personal liquidity. They want to know that the people standing behind the bond have the financial resources to back up the guarantee.
Keep this document updated annually. If you have significant changes in your personal financial position, such as buying or selling real estate, taking on new debt, or receiving an inheritance, update your personal financial statement before your next underwriting submission.
Work-in-Progress Schedule
Your work-in-progress (WIP) schedule shows the surety exactly what you have going on right now. It lists every active project, including the contract amount, costs incurred to date, billings to date, estimated cost to complete, and percentage complete.
The WIP serves two purposes in underwriting. First, it shows the surety how much of your current bonding capacity is being used. If your aggregate limit is $5 million and your WIP shows $4.5 million in active bonded work, the surety knows there is very little room for another project. Second, it shows whether your jobs are profitable. If your costs to date are running ahead of your billings and estimated completion percentages, the surety sees potential trouble.
Accuracy is critical. Inconsistencies between your WIP and your financial statements create questions that slow down underwriting. Your CPA should be involved in preparing or reviewing your WIP, especially if you use percentage-of-completion accounting.
Update your WIP at least quarterly. If you are actively bidding large work or requesting capacity increases, monthly updates give the surety the most current picture.
Completed Project List
Your completed project list demonstrates your track record. This document shows every significant project you have completed, including the project name, the project owner, the contract value, the type of work performed, and the completion date.
Sureties use this to evaluate experience. They want to see that you have successfully completed projects similar in size, scope, and complexity to the one you are now asking them to bond. A contractor who has completed ten $1 million highway projects has a much stronger case for a $2 million highway bond than a contractor with no comparable experience.
Keep your completed project list current and detailed. Include both bonded and non-bonded work. The more comprehensive the list, the easier it is for the surety to match your experience to the project you want to bid.
Business and Organizational Documents
The surety needs to understand your company's legal structure and ownership. Depending on your entity type, this typically includes articles of incorporation or organization, operating agreements or bylaws, a list of all owners with their ownership percentages, and current business licenses.
If your company has changed ownership, merged with another entity, or undergone any structural changes in recent years, include documentation explaining those changes. Sureties pay close attention to ownership transitions because they affect who is personally indemnifying the bond and who is managing the company's operations.
Bank Reference and Line of Credit Information
Your banking relationship is an important part of your underwriting file. The surety wants to know that you have adequate access to capital to fund project operations between payment cycles. Construction is a cash-intensive business, and sureties are more comfortable bonding contractors who have a line of credit or established banking relationship that demonstrates liquidity.
Provide a bank reference letter that includes your account history, average balances, and credit line details. If you have a revolving line of credit, include the limit, current balance, and terms.
A strong banking relationship does more than just look good on paper. It signals to the surety that a financial institution has already evaluated your business and extended trust. That independent validation carries weight in underwriting.
Company Resume and Key Personnel
Your company resume tells the surety who you are beyond the numbers. It should cover your company's history, the types of work you specialize in, your geographic scope, your key personnel and their qualifications, and your safety record.
Key personnel information is especially important. The surety wants to know who is managing the projects they are bonding. Include resumes for your project managers, superintendents, and estimators. If your key people have decades of experience in the type of work you are bidding, that strengthens your file. If you are a one-person operation, the surety needs to understand your plan for managing multiple projects simultaneously, which ties directly into your perpetuation plan.
Your safety record matters too. A history of significant OSHA violations or high workers' compensation claims can raise concerns in underwriting. A strong EMR (experience modification rate) and a documented safety program work in your favor.
Credit Reports
The surety will pull credit reports on the business and on every individual who will be signing the indemnity agreement. Personal credit scores are a major factor in underwriting, especially for smaller bond programs where a one-page credit-based application is the standard process.
For credit-based bonds, typically up to $500,000 or $1 million in single job size, depending on the surety, your personal credit score may be the primary underwriting criterion. For larger programs, credit is still important but it is weighed alongside the full financial picture in your underwriting file.
If your credit has issues, do not hide from them. Address them proactively with your bond agent. Sureties are more understanding of credit challenges when the contractor explains the circumstances and demonstrates steps taken to improve. A bankruptcy from ten years ago that has been fully resolved is very different from active collections and delinquent accounts.

The Specific Project Information
When you are requesting a bond for a specific project, the surety will also need information about that particular job. This typically includes the bid invitation or contract documents, the project specifications, the project timeline, your cost estimate or bid breakdown, and any special conditions or requirements in the contract.
The surety reviews this information to assess the risk of the specific project you want to bond. They are evaluating whether the project is within your experience range, whether your cost estimate is realistic, whether the timeline is achievable, and whether the contract terms contain any unusual risk factors such as liquidated damages clauses, design-build responsibilities, or subcontractor default provisions.
Your bond agent should review the contract terms with you before the surety sees them. At Grit, we flag anything in a contract that might give the surety pause and help you address it before it becomes a problem.
How to Organize Your Underwriting File
The best underwriting files are organized, current, and easy to navigate. Here is how to keep yours in shape.
Keep all documents in a single digital folder, organized by category: company financials, personal financials, WIP, completed projects, organizational documents, bank references, resumes, and project-specific documents. Name files clearly so anyone reviewing the folder can find what they need without guessing.
Update your file at least annually after your fiscal year-end financials are complete. If you are actively bidding bonded work throughout the year, maintain your WIP and completed project list on a rolling basis so they are always current.
Build your file before you need it. The worst time to assemble an underwriting file is when you have a bid deadline in 48 hours. Contractors who maintain a current file can respond to bonding opportunities quickly, which is a competitive advantage.

What Happens After You Submit Your File
Once your underwriting file is submitted, your bond agent sends it to the surety for review. The underwriter evaluates your financial strength, your experience, your creditworthiness, and the details of the project you want to bond. They may come back with questions or requests for additional information.
The speed of this process depends almost entirely on the quality of your submission. A complete, well-organized file with current documents can be underwritten in days. An incomplete file with outdated financials and missing documents can take weeks, and it signals to the surety that you may not manage your projects with the same level of attention.
At Grit, we review your underwriting file before it goes to the surety. We know what underwriters look for, and we help you address gaps, answer potential questions in advance, and present your company in the strongest possible light. That is part of what it means to have a bond advisor, not just a bond broker.
