Commercial Project Benchmarks
Commercial and GC work can combine WIP, PO commitments, contractual billing and surety requirements. Use 10-20% gross margin as a planning sensitivity here, not a measured sector range or a ranking against other contracting work.
Key Finding
Dozens of jobs open 90+ days without an invoice, on a single contractor's books
One contractor review found dozens of jobs open more than 90 days with no invoice sent. This is a reported single-case observation, not a measured sector frequency or certified recovery amount. Before calling it leakage, verify completed work, logged cost, the contractual billing cutoff, retainage and any parent or consolidated invoice. The same contractor had over half of active jobs with no assigned project manager.
Illustrative sensitivity: genuinely lost billing equal to 5% of revenue is large beside a 10-15% gross-margin pool. Timing differences and collectible WIP are different problems; the exception list does not establish lost profit.
Commercial Project Operating References
These are Level planning bands, not measured commercial-project percentiles. The reported individual reviews below do not establish the table distribution. Use the bands to prioritize questions, then reconcile your own WIP and contractual billing requirements.
| Metric | Lower reference | Center reference | Upper reference | Note |
|---|---|---|---|---|
| Gross Margin | < 8% | 10-15% | 18-20% | Planning band; compare self-performance and subcontract scope |
| Jobs Open 90+ Days Without Invoice | 15%+ of open jobs | 5-10% | < 2% | Age is an exception cue; verify completion and billing status |
| Jobs With Assigned PM | < 50% | 60-70% | 90%+ | Test job ownership against commitments and change orders |
| WIP Schedule Update Frequency | Updated quarterly or less | Updated monthly | Updated weekly | Surety companies underwrite based on WIP quality |
| Vendor Concentration (Top 5) | > 60% of PO spend | 35-45% | < 30% | Concentration is leverage or risk, needs active management |
| Bonding Ratio (Revenue/Working Capital) | > 20:1 | 10:1-15:1 | < 8:1 | Sureties look for clean financials and strong working capital |
What to test in your own records
dozens of jobs open 90+ days, no invoice
One contractor review found dozens of jobs open more than 90 days with no invoice sent. Age alone does not establish leakage. Test completed work and logged costs against invoice IDs, contract milestones, retainage and parent billing. The report is an exception queue, not a verified recovery amount.
Over half of jobs had no assigned PM
One reported review found more than half of active jobs without a named project manager. That is not proof that no one owned the work or that margin was lost. Reconcile responsible staff, PO commitments and change-order approvals. A 2-5-margin-point downside against a 10-20% starting margin is a planning sensitivity, not measured damage.
~$40M PO spend, top 5 vendors = about 39%
Vendor concentration data from one commercial contractor: ~$40M in annual PO spend with the top 5 vendors representing about 39%. One review does not establish sector prevalence or a savings percentage. Compare your own negotiated terms and rebate eligibility with actual payments and credits before estimating a benefit.
Bonding capacity is a financial statement problem
Working capital, net worth and WIP can inform underwriting, but this page does not establish a universal bonding limit or access to a project. Review the surety's adjustments, contract conditions, backlog and indemnity requirements with the actual underwriting team.
The CLEAR Framework for Contractors
Learn moreUse these five financial pillars to organize the review. The checks below combine operating scenarios with separately scoped measured data.
Expand all 5 CLEAR financial pillars (Cash, Labor, Earnings, Accounts, Risk)
DSO, invoice speed, retainage, progress billing. The gap between completing work and collecting payment can trap cash.
Technician utilization, billable hours, and callback rates. At 60% utilization, 40% of paid hours sit outside billable work; travel, training, demand and role design determine how much is recoverable.
Job-level margins, service agreement profitability, install vs service mix. Total margin can hide which jobs are underwater.
Quote conversion, pull-through revenue and retention. Additional annual revenue from agreement customers divided by agreement revenue has a 8.7% median and 29.6% p75 across 386 eligible companies; these are observed ratios, not a causal sales lift.
Customer concentration, warranty exposure and bonding capacity. A 20% customer share is a review scenario: test lost contribution, committed costs, contract notice and available cash rather than assume a cash crisis.
Frequently Asked Questions
What is a good gross margin for commercial construction projects?
The 10-15% center and 18-20% upper references here are planning bands, with no published commercial-project percentile sample. Self-performed work and subcontracted work have different cost structures, so compare like scope and accounting definitions. Test gross margin alongside earned revenue, estimated cost to complete, PO commitments and approved change orders before treating an apparent improvement as profit.
How does bonding capacity affect commercial contractors?
Working capital, net worth and WIP information can inform surety underwriting. The 20:1 and 8:1 ratios here are planning references, not measured quartiles or universal surety limits. Confirm the working-capital adjustments and underwriting requirements with your surety. Ask which financial statements and supporting schedules your underwriting team requires.
What is a good WIP schedule update frequency?
Weekly, monthly and quarterly are operating-cadence references here, not surveyed percentile groups. A weekly review may surface a changed estimate sooner, but frequency alone proves neither accuracy nor avoided loss. Confirm the surety's actual reporting requirement and reconcile source costs and completion inputs.
How does vendor concentration affect commercial contractors?
Data from one commercial contractor showed ~$40M in annual PO spend with the top 5 vendors representing about 39%. That is a single-case observation, not a sector distribution. Pull twelve months of AP and PO commitments for your own top five vendors, then compare negotiated terms, earned rebates, actual credits and substitute suppliers. A concentration ratio alone proves no savings opportunity.
Operating review
Questions before treating profit as cash
The margin, cash, and operating questions we check first when reviewing your numbers.
What completed work has not yet become an invoice?
Completion, billing and collection are separate events. A profitable job can still be waiting for a billing handoff.
Which invoices explain the next cash shortfall?
Total receivables can conceal a few large balances that matter more than many small invoices.
Does the cash forecast include the next payroll funding event?
A completed or approved payroll run does not establish the date and net amount that will leave the bank.
