Sureties are not in the business of guessing. When a contractor requests a performance bond, the underwriter’s first question is simple: can this firm fulfill the contract and survive the unexpected? The answer lives in the financials. When those financials are prepared by a construction-savvy CPA, the conversation with the surety changes. Risk becomes measurable. Equity and liquidity are real, not paper-thin. Backlogs look executable, not aspirational. And the bond program grows responsibly, often faster than owners expect.
This is not an accounting vanity play. It is a practical, high‑leverage decision for any contractor that wants to move from small jobs to multi‑million dollar projects, or that needs to keep bonding capacity available when the market turns. I have sat with owners whose in‑house QuickBooks file told one story and a CPA‑prepared, percentage‑of‑completion statement told another. The second story won them capacity, better rates, and a calmer phone call when a project wobbled midstream.
What underwriters look for when pricing and approving a performance bond
Underwriters think in terms of ability to perform and ability to absorb loss. They solve for two things at once: the contractor’s individual risk profile and the risk profile of the job to be bonded. They will always ask for at least three years of financial statements, interim statements for the current year, work‑in‑progress (WIP) schedules, corporate and personal tax returns, banking and credit references, and details on the specific project. The data is not formalism. It feeds specific calculations and stress tests that point to whether the surety can stand behind the contractor without losing sleep.
A common misunderstanding is that sureties lean only on net income. They do not. They focus on quality and composition of equity, liquidity relative to backlog, the accuracy of WIP reporting, and the trend of margins through cycles. Ratios matter, but the story behind the ratios matters more. A contractor with slim margins but clean WIP, disciplined cash management, and strong project controls can receive better terms than a firm with fat headline profits masked by chronic underbilling and unapproved change orders.
CPA‑prepared financials raise the credibility of every number in that analysis. They also provide the context underwriters require to underwrite construction risk properly, not as if it were retail or manufacturing.
The difference between compiled, reviewed, and audited statements
Not all CPA work carries the same weight. Compiled statements present numbers provided by management with no assurance. Reviewed statements add limited assurance through inquiry and analytics, catching obvious misstatements and reconciling key schedules. Audited statements provide reasonable assurance, with testing of transactions, internal controls, and confirmations with third parties like banks and customers.
Sureties generally accept reviewed financials for small to mid‑sized bond programs, and they may require audited statements as bond sizes climb or when a contractor has thin equity or a rocky history. The incremental cost from compilation to review is not trivial, but the trade‑off is clear: reviewed statements reduce uncertainty, which often translates to higher single and aggregate bond limits and more favorable rates.
From experience, the jump in bonding capacity can be meaningful. I have seen firms move from a single job limit of roughly 1.5 times working capital under compiled statements to 2.0 times or better once they provide reviewed financials with clean WIP and reconciled retainage. The factors vary by surety, but the pattern holds. Better assurance equals better outcomes.
Why construction‑specific accounting matters more than formats
Construction is project‑based, margin‑thin, and timing‑sensitive. Underbilling by a million dollars on a $20 million backlog can mean the difference between a comfortable current ratio and a breach of loan covenants. That is why thoughtful percentage‑of‑completion accounting is the backbone of a strong bond file.
A general‑purpose CPA can close a set of books, but a construction CPA understands:
- How to apply percentage‑of‑completion consistently, including the cost‑to‑cost method and proper treatment of uninstalled materials. The WIP schedule’s role in capturing earned revenue, over/underbillings, and projected final gross margins. The importance of segregating retainage receivable and payable, both for liquidity analysis and lien management. The handling of indirect job costs, mobilization, stored materials, and change orders, including claims and pending approvals. The practical presentation of backlog detail, bonding history, and contractor prequalification needs.
These are not cosmetic choices. They change reported equity and working capital in ways that underwriters respect. For instance, properly recognizing revenue on a long‑duration project with stored materials can improve gross profit recognition in the current year, which then supports higher capacity, provided the WIP shows those profits are earned, not speculative.
The WIP schedule is the underwriter’s truth serum
If a single document decides your performance bond fate, it is the WIP schedule. On one sheet, it shows the revenue recognized to date, cost incurred, estimated cost to complete, billings, and whether the job is overbilled or underbilled. It also reveals whether original margins are holding, slipping, or improving.
A sloppy WIP with rounded figures, stale estimates, and unapproved change orders treated as earned revenue erodes trust instantly. A clean WIP, reconciled to the general ledger and supported by job cost reports, tells a different story. Underwriters use that story to test liquidity. Overbillings create cash but also liabilities, because the contractor owes performance before the revenue is earned. Underbillings tie up cash and signal potential collection risk if they arise from slow change order approvals.
An experienced CPA will not simply format the WIP. They will challenge the EACs, ask why Job 14 slipped 300 basis points last quarter, and ensure that the “profit in excess of billings” balance ties to specific projects the underwriter can review. That rigor produces fewer surprises, and fewer surprises mean easier approvals.
Key ratios and metrics, and how CPA inputs move them
Underwriters do not worship ratios, but they rely on them as quick diagnostics. The way financials are prepared drives these numbers:
- Working capital: current assets less current liabilities, adjusted to exclude illiquid items. Clean CPA statements break out retainage receivable, eliminate related‑party fluff from current assets, and correctly classify the portion of long‑term debt due within a year. Sureties typically base single job limits on a multiple of working capital, often between 10 and 20 times, subject to other risk factors. Distorted current assets from old receivables or optimistic underbillings choke capacity. Equity and debt‑to‑equity: net worth supports absorption of losses and project volatility. Aggressive distributions to owners, especially late in the year, can crater bonding capacity even if profits look healthy. A CPA who understands bonding will counsel on right‑sizing distributions, using sub debt with proper subordination agreements when needed, and documenting loans from owners correctly. Profit fade: underwriters track whether jobs lose margin as they progress. A WIP showing consistent fade without cause invites scrutiny. A CPA who forces monthly EAC updates and ties them to field reports can prevent unintentional fade and maintain credibility when a job legitimately runs into unforeseen conditions. Backlog to working capital: a simple stress gauge. Too much backlog relative to working capital signals execution and cash‑flow risk. Transparent CPA statements let underwriters model that risk accurately rather than pad it with conservative assumptions.
There is also the qualitative metric of management discipline. Accurate cutoffs, timely close processes, and traceable reconciliations indicate the company can handle growth. Sloppy accounting screams at the surety that project controls may be equally loose.
Real‑world scenarios where CPA‑prepared financials changed the outcome
A mechanical contractor in the Midwest hit a ceiling at a $3 million single bond limit despite strong demand. They had compiled statements, no WIP schedule, and a habit of booking change orders when requested, not when approved. The surety haircut their underbillings and discounted equity that sat inside related‑party receivables. After moving to reviewed statements with a robust WIP, they trimmed phantom assets, recognized revenue properly, and posted realistic EACs. Capacity moved to a $6 million single and $12 million aggregate within two renewal cycles, and their rate dropped by 50 to 75 basis points.
In another case, a site contractor with a $20 million backlog had a current ratio north of 2.0 on internally prepared statements. A construction CPA reclassified $2.5 million of retainage, moved $1.2 million of long‑term debt to current, and adjusted underbillings tied to unapproved changes. The current ratio fell to 1.4, which spooked management, but the surety’s confidence increased because the picture was honest. With a cash‑flow plan backed by the CPA’s forecast, the underwriter approved a $7 million bond needed to win a DOT job. They would not have approved it based on the original, rosier but less reliable numbers.
CPA participation in prequalification can win you the job
Owners and general contractors have become more rigorous about prequalification, especially after a wave of mid‑project contractor defaults in recent years. They ask for bonding letters, evidence of aggregate capacity, and sometimes direct input from your CPA. A partner‑level CPA who can speak to your internal controls, WIP discipline, and cash‑flow forecasting adds weight to your submission. I have watched selection committees relax when they hear a CPA explain how underbillings are monitored weekly and how material price volatility is hedged in subcontracts.
This credibility does not replace performance. It buys you the chance to compete on equal footing with larger firms. For privately negotiated jobs, it can tilt the decision.
How timing and cadence improve outcomes more than heroics
Underwriters prefer rhythm to rescue. Quarterly reviewed financials are expensive for many firms, but timely interim statements, even if internally prepared, keep your story current between annual reviews. The sweet spot I have seen work well is annual reviewed statements with monthly internal closes that the CPA helps design and occasionally audits. The interim reports include WIP, a 13‑week cash‑flow, AR aging with retainage breakout, and job‑level margin analysis.
Speed matters when a large project suddenly becomes available. If your last reviewed statement is 14 months old and your internal WIP is stale, you will scramble to refresh the file while competitors submit clean packages. On the other hand, if you can hand your agent a month‑end WIP tied out to the general ledger and a trailing twelve‑month income statement, the surety can underwrite within days, not weeks.
Where financial presentation and operational practice intersect
Good financials do not save bad operations, but they often reveal the fix early. Underbilling that grows for three months straight usually signals change orders getting stuck or a PM who is slow to process billing cutoffs. A CPA who tracks underbilling by job and flags outliers gives management a prompt to act. Overbilling that balloons can mask margin fade if EACs are not updated. The right WIP process forces job teams to confront reality.
Another crossover area is subcontractor management. Sureties like to see strong prequalification of subs, the use of pay‑when‑paid clauses where permitted, and prompt lien waivers. A CPA with construction depth will suggest reporting that ties subcontracts to committed costs, shows uninsured subs separately for risk pricing, and highlights concentration exposure to a few critical trades. It is easier to convince an underwriter that a heavy civil job is manageable if your sub exposure is diversified and documented.
Building a financial foundation that supports higher bond capacity
There is no magic spreadsheet. The foundation is boring and powerful: consistently profitable jobs, adequate equity, and real liquidity. CPA‑prepared financials improve the measurement of each piece and help you make better choices with your cash.
Owners often ask how much equity is enough. The honest answer is that it depends on your mix of public and private work, average job duration, and volatility. As a general guide, mid‑market contractors targeting single bonds in the $10 to $25 million range often carry equity equal to 8 to 15 percent of annual revenues, with working capital at 5 to 10 percent. Firms performing short‑duration service work can succeed with less; firms doing long‑duration heavy construction usually need more. A construction CPA will benchmark you against your peer group and tailor goals to your backlog profile.
Debt is not the enemy. Debt without cash‑flow discipline is. Equipment‑heavy contractors who use term debt aligned with asset life, maintain loan‑to‑value ratios that leave equity in the gear, and avoid stacking short‑term borrowings to plug operating deficits generally receive favorable treatment. CPAs can document these disciplines clearly so the surety sees the structure and the covenants, not just the balance.
The economics: cost of CPA work versus bond capacity and rate
Contractors sometimes balk at the cost of reviewed or audited statements, which can range from tens of thousands to low six figures depending on size and complexity. Measure that against the economics of improved bonding. On a $10 million performance bond with a 1 percent premium, 25 basis points off the rate saves $25,000. If your improved financials unlock a $5 million job you could not access before, the return on the accounting investment becomes obvious.
There is also a hidden dividend. Better financials often uncover dormant cash. Cleaning up billing processes, tightening retainage follow‑up, and identifying change orders stuck in legal review can free hundreds of thousands of dollars inside a year for mid‑sized firms. That liquidity boosts both operations and your bonding capacity, without new capital.
Selecting the right CPA for bonding success
Not every CPA who can deliver a clean report can deliver bonding value. Look for proof of construction expertise. Ask about their client list and whether they produce WIP schedules routinely. Request examples of how they have helped a contractor increase capacity or improve a rate. Talk to your surety agent and underwriter; they will tell you which firms they trust and why.
Also consider the CPA’s willingness to engage beyond year‑end. You need a partner who will review interim WIP, answer underwriter questions directly, and help you prepare for prequalification meetings. The best relationships feel collaborative, not transactional. They educate your project managers on cost‑to‑complete updates and help your controller enforce close discipline. Over a two‑year arc, that partnership changes your financial profile and your bond story.
What to fix first if your bonding program is stuck
If your surety has capped your single job limit or raised your rate, the reasons usually trace to a few fixable sources. Start with your WIP. If it does not tie Swiftbonds reviews to the general ledger, rebuild it. If EACs are static, force monthly updates and document assumptions. If underbillings are high, identify whether the cause is slow approval, poor documentation, or deliberate strategy. Next, examine equity movements. If distributions outpace profits, scale back until capacity stabilizes. If related‑party balances clutter the balance sheet, clean them and document terms. Finally, segregate retainage and track collection. Underwriters will discount old retainage heavily.
Your CPA should drive this triage with you. The goal is a clean narrative for the underwriter: here were the issues, here are the changes, here is the evidence in the latest interim statements. That storyline, delivered by a credible CPA, wins back capacity more often than a raw plea for flexibility.
The role of cash‑flow forecasting in performance risk
Most contractors do not fail due to lack of profits. They fail due to lack of cash at critical moments. A 13‑week cash‑flow forecast, updated weekly, is the single most practical tool you can add to your bond file. It shows the surety you can map receipts and disbursements around payroll, subs, and supplier draws. Your CPA can help design a forecast that integrates with your WIP and AR aging, including realistic timing for retainage release and change order collections. For firms with seasonal swings, this forecast reassures the surety that you will not starve a large project mid‑winter when equipment notes, insurance renewals, and tax deposits crowd the same weeks.
A strong cash‑flow culture also changes behavior downstream. Project managers who see the impact of late billings on the forecast push harder for approvals. Controllers who watch vendor terms by trade negotiate smarter. The surety sees those habits in your numbers, and it lightens their view of your performance risk.
How CPA‑prepared financials reduce turbulence when a project goes sideways
Every contractor eventually faces a troubled job. The difference between a tough conversation and a crisis is often the quality of your financial reporting. When a rock excavation runs over budget or a supplier default stalls delivery, the CPA’s documentation of EAC revisions, claim recognition, and loss accruals becomes the underwriter’s lifeline. They can model the hit, weigh it against equity, and decide whether to support a waiver or an extension. Without that clarity, the surety may pull back, exactly when you need them most.
I have seen underwriters grant consent to slow pay certain subs or to reallocate equipment between jobs because the contractor’s CPA provided a granular picture of the cash impact and the recovery plan. That kind of support is not guaranteed. It is earned by years of clean reporting and honest updates.
Pulling it together into a durable bond strategy
A performance bond is a promise backed by math and judgment. CPA‑prepared financials sharpen both. They transform your WIP from a spreadsheet into a control system, your balance sheet from a snapshot into a reservoir, and your income statement from a brag into a plan. Underwriters lean into contractors who invest in that clarity. They reward them with capacity that grows alongside their capabilities, not ahead of them and certainly not behind.
If you are serious about expanding your bond program, build a three‑part plan with your CPA and bond agent. First, commit to reviewed statements and a monthly WIP that ties to the ledger, with EACs updated by project managers and challenged by finance. Second, set equity and working capital targets that fit your backlog profile, and align your distribution policy and debt structure accordingly. Third, institutionalize a 13‑week cash‑flow forecast and retainage tracking that both management and the surety can trust.
Do those things consistently, and your next conversation about a large performance bond will feel less like a pitch and more like a routine. That is the point. Predictability is the currency sureties trade in. A construction‑savvy CPA helps you mint it.
