What a Bonding Company Looks for in a Contractor's Financials

Your bonding capacity is not a number a surety pulls out of the air. It is underwritten directly off your financial statements. Which means your contractor bonding financials are the single biggest cap on the size of the jobs you're allowed to bid.

Here's the part nobody tells general contractors until it's too late: messy books don't just annoy your accountant. They quietly shrink your bonding line. The surety can't price a risk it can't read, so when your numbers are sloppy, they assume the worst and bond you smaller. You lose the $4M job not because you can't build it, but because your balance sheet says you can't.

So before you bid bigger, you need to know what the underwriter is actually staring at.

A surety isn't a lender — they're betting you'll finish

Banks lend you money and expect it back with interest. A surety doesn't lend you anything. A surety bond is a three-party promise that you will complete the job, and if you don't, the surety pays to get it finished — then comes after you to recover every dollar.

That changes what they care about. A lender wants to know you can repay. A surety wants to know you won't blow up mid-project. So the whole review of your surety bond financial requirements is really one question dressed up in spreadsheets: if this contractor takes on more work, do they have the financial cushion to absorb a bad job without going under?

Everything below is them answering that.

Your WIP schedule is the document they read first

If you take one thing from this post: fix your work-in-progress schedule.

A WIP schedule lists every open job with the contract value, costs incurred to date, your estimate to complete, and how much you've billed. From that, the underwriter calculates whether each job is overbilled (you've invoiced ahead of the work — borrowing from the future) or underbilled (you've done work you haven't billed — a hidden asset, or a sign you're losing control of billing).

WIP schedule bonding analysis is where sureties find the truth your income statement hides. A contractor can look profitable on paper while sitting on a stack of jobs bleeding money. The WIP shows it. A pattern of jobs whose estimated costs keep climbing tells the underwriter you can't estimate — and estimating is the whole business.

Underbillings that pile up scare them just as much. It usually means your billing is disorganized, which means your cash is tied up in work you've already paid for. Clean, accurate, job-by-job WIP is the difference between a surety that trusts your numbers and one that discounts them.

Working capital and net worth set the actual size of your line

Two numbers move your bonding line up or down more than anything else.

Working capital — current assets minus current liabilities — is the surety's read on whether you can fund payroll, materials, and subs while you wait to get paid. Construction runs on float, and float runs on working capital. A common rule of thumb: sureties extend single-job bonding capacity at roughly 10x working capital and aggregate capacity around 10x to 20x. So $500K of working capital might support a single bond near $5M and a program around $5M–$10M.

Net worth — what's left after liabilities — backs the bigger relationship. The two work together: strong working capital gets you bonded for the job in front of you, and strong net worth tells the surety you can keep growing.

Here's the lever most owners miss. A $200K shareholder loan you took out as a "distribution," or $150K in slow receivables you never wrote off, both drag your working capital down — and at 10x, that's potentially $2M to $3.5M of bonding capacity you erased with two bad bookkeeping habits. The math is unforgiving, and it runs against you when your books are loose.

Why cash-basis contractor bonding financials get declined

You can run a small contracting shop on cash-basis accounting. You cannot get a meaningful bond on it.

Sureties expect percentage-of-completion accounting — recognizing revenue as a job progresses, governed under ASC 606 (which superseded the old ASC 605-35 construction guidance). It's the only method that matches revenue to the work actually done, and it's what makes a WIP schedule meaningful in the first place.

Cash-basis books recognize money when it moves, so a contractor who collected a big deposit looks flush in March and broke in July — useless for judging whether you can carry a year-long project. Percentage-of-completion smooths that into reality. If your statements aren't built this way, you're effectively asking the surety to underwrite blind. They'll either decline or bond you at a fraction of what you're capable of.

Who prepares your statements changes how much they're worth

A surety weights your financials by who stands behind them.

The ladder runs: internally prepared statements at the bottom, then a CPA compilation, then a review, and an audit at the top. Internally prepared numbers carry the least weight because nobody independent checked them. A reviewed or audited statement from a CPA who actually knows construction carries the most — and unlocks the most bonding capacity.

The "knows construction" part matters more than the credential. A generalist CPA who treats your WIP as an afterthought can hand the surety a technically clean statement that still tells the wrong story. A construction-literate CPA builds the WIP, the schedules, and the footnotes the way an underwriter wants to read them — which is half of getting approved.

Get your contractor bonding financials ready before you need the bond

If your bonding line feels smaller than your ambition, the fix usually isn't more revenue. It's financials an underwriter can trust — a clean WIP, percentage-of-completion statements, and working capital that isn't quietly leaking into shareholder loans and stale receivables.

That's a job for an accountant who lives in construction, not one who files your return and disappears until April.
