BONDING READINESS FOR SUBCONTRACTORS
Sureties don’t look at revenue. They look at four things: working capital ratio (typically 20%+ of largest single project), net worth quality (cash and AR strong, intangibles weak), WIP schedule accuracy (POC math defensible, gross profit recognition consistent), and 3-year financial trend stability. Subs that bond up to $5M aggregate without thinking about it usually have all four naturally. Subs trying to bond up to $10M–$25M aggregate hit a wall because the financial structure underneath isn’t surety-ready. Fixing it is mechanical, not aspirational — and most engagements get there inside 12 months.
Your bonding capacity is a financial structure decision, not a revenue achievement. The surety reads the balance sheet, not the backlog.
THE FOUR EVALUATION CRITERIA
WORKING CAPITAL RATIO
Sureties look at working capital (current assets minus current liabilities) relative to the largest single project bond being requested. Standard underwriting target: working capital at least 20% of the single project amount. For a $3M single project bond, that means at least $600K of working capital. For $5M, at least $1M. The math is mechanical — below the threshold, the bond limit doesn’t move regardless of revenue.
What counts as working capital quality: Cash and current AR count fully. Inventory counts at discount. WIP under/overbilling counts depending on direction. Related-party receivables and intangibles get discounted heavily or excluded.
NET WORTH QUALITY
Stated net worth and tangible net worth aren’t the same. Sureties look at tangible net worth after stripping goodwill, intangibles, related-party receivables, deferred tax assets, and questionable inventory. A balance sheet showing $2.4M stated net worth might only support $1.6M of tangible net worth after surety adjustments. Bonding capacity scales against the adjusted number, not the headline.
What strengthens net worth quality: Cash position, current AR with strong aging, equipment with clear titles and current valuations, retained earnings growth over multiple years. What weakens it: heavy intangibles, related-party transactions, single-customer concentration above 35–40%, AR aged past 90 days.
WIP SCHEDULE ACCURACY
Sureties spend more time on the WIP schedule than on any other single document. They’re looking for: POC math that ties to the income statement, gross profit recognition consistency across projects, billings-in-excess vs. costs-in-excess movement that makes sense given project type, no margin pickups that look like loss adjustments, and project-level data that reconciles to the books. WIP errors get found in underwriting, and they reduce or eliminate bonding capacity immediately.
Common WIP red flags: Gross profit jumping 5+ points from prior period without explanation, large adjustments between draft and final WIP, costs-to-complete that haven’t been updated in months, projects that close out at margins materially different from how they progressed.
3-YEAR TREND STABILITY
Sureties want to see consistent or improving trends across 3 years: revenue growth that’s sustainable, gross margin stability, net worth accumulation, working capital growth keeping pace with revenue. Volatile patterns — profitable year, loss year, profitable year — raise underwriting concern even when the current period looks strong. The story has to be coherent across the trailing 3 years.
What sureties read as instability: Year-over-year revenue swings beyond 25%, gross margin variation of 5+ points between years, retained earnings decreases, working capital decreases despite revenue growth, large related-party transactions that change between years.
THE STRUCTURE UNDERNEATH
Bonding readiness isn’t a single document or filing. It’s the cumulative result of operating disciplines that produce surety-friendly financials month after month. The disciplines:
- Monthly WIP schedules with POC math reviewed and validated. Costs-to-complete updated by project managers monthly. Gross profit recognition reasoned and documented.
- Reviewed-quality financials minimum. Compiled-only financials severely limit bonding capacity. Reviewed financials open access to $5M–$10M aggregate. Audited financials open access to $15M–$30M+ aggregate depending on trade and surety relationship.
- Working capital management discipline. Cash conversion cycle managed, AR aging tracked, retention release pursued. Working capital growth tracks ahead of revenue growth.
- Customer concentration management. No single GC or owner above 35–40% of revenue. Diversification by client and by trade scope where possible.
- Clean balance sheet maintenance. Intangibles minimized, related-party transactions documented and arms-length, equipment titles current, prepaids amortized properly.
- Surety relationship development. Quarterly check-ins, transparent communication on project performance, advance notice of capacity needs. Sureties extend more capacity to subs who manage the relationship proactively.
HOW MUCH CAPACITY YOUR STRUCTURE SUPPORTS
For a typical commercial subcontractor, the rough relationship between financial structure and bonding capacity:
Compiled financials, $400K working capital, $1M net worth: Single project $500K–$1M, aggregate $1.5M–$3M.
Compiled financials, $1M working capital, $2M net worth: Single project $1M–$2M, aggregate $3M–$5M.
Reviewed financials, $1.5M working capital, $3M net worth: Single project $2.5M–$4M, aggregate $6M–$10M.
Reviewed financials, $2.5M working capital, $5M net worth: Single project $5M–$8M, aggregate $12M–$20M.
Audited financials, $5M+ working capital, $10M+ net worth: Single project $10M–$25M+, aggregate $25M–$50M+.
Trade-specific factors affect the ranges. Higher-risk trades (excavation, demolition, marine) get tighter ratios. Lower-risk trades (electrical finish, interior trades) get more capacity per dollar of working capital. The surety relationship and historical performance matter at the margins, but the underlying math sets the floor.
Bonding capacity isn’t something you ask for. It’s something your financials produce. The question is whether the financials underneath are surety-ready.
SURETY-READY IS BUILT IN
CFOS treats bonding readiness as a structural outcome of running the framework correctly. WIP schedules get produced monthly with POC math validated. Working capital management is a managed metric. Customer concentration gets monitored. The financial package handed to the CPA at year-end is positioned for review or audit quality, not just compilation. Quarterly surety relationship management gets calendared.
The result: bonding capacity grows organically as the financial structure strengthens. Subs that work through CFOS typically see single-project capacity grow 2–3x within 18 months and aggregate capacity grow 3–5x, without any single bond renewal looking like a heavy lift.
