Trades operating benchmarks
The numbers a healthy HVAC, plumbing, or electrical business runs against — the same targets a PE-grade operator uses to judge whether a shop is leaving margin on the table.
These are operator benchmarks — ranges observed across running multi-trade home-services companies and used for owner planning. They are guides for judging your own numbers, not a formal industry survey. Cite them as "IronMargin operator benchmark, 2026."
Margin & profitability
Typical net margin band for a trades business doing $1M–$15M. Shops at the low end usually share three problems: stale flat-rate pricing, low maintenance attachment, and unreviewed supply-house pricing.
Healthy blended gross margin by job type. A wide spread by technician usually signals inconsistent parts markup.
Benchmark for a well-managed shop. Many owners sit at 28% because they have a supply-house relationship but no formal pricing agreement.
Labour & productivity
Billable hours ÷ paid hours. Most owners pay for 40 hours and bill 22–26 without realising it — the single largest hidden leak in the trades.
Share of paid hours spent in the windshield. Above this, route density and dispatch batching need attention.
A front-loaded day starts with the first tech on-site by 8:00am, not 9:30am after coffee.
Pricing, parts & inventory
Enforced with a tiered matrix: 40% fast-moving, 50% specialty, 60% emergency or after-hours. Per-tech spread should stay under 5%.
Annual parts cost ÷ average truck inventory. Low turns mean cash is tied up in rolling stock and shrinkage.
Discounts ÷ gross revenue. A reflexive discount habit quietly erodes the average ticket.
Service quality & retention
Callback jobs ÷ total jobs. Above 5% is a warning sign — track cause (warranty vs training vs service), not just the count.
Inbound calls that become booked jobs, for a well-trained CSR team with a scripted call flow. Many shops sit near 72%.
Share of customers on a maintenance agreement. Moving from 15% to 30% roughly doubles recurring revenue and lifts the exit multiple.
Purchasing & exit value
Conservative blended rebate on aggregated purchasing across supply, fleet, uniforms, insurance, and financial services. Multi-trade operations at scale often see 4–5%.
The gap between a 4x and a 6x outcome is built into the numbers over the 24 months before a sale — clean add-backs, revenue mix, and reduced key-man risk.
A single truck at −5% margin on $300,000 of revenue loses about $15,000 a year, often hidden inside a blended P&L for years.
