Sales don't guarantee profit. You can run busy crews all season and still be broke at month's end. The answer is almost always hiding in the numbers. Everything below helps you find it yourself. Start wherever your gut says you're bleeding.
Two quick self-checks. One tests whether your cash flow is healthy; the other tests whether your books are hiding money. Be honest as most owners find at least a couple that sting.
Check every statement that applies to your business. You will get a score and a straight read on where your cash flow stands.
We will walk through your results together and find the biggest leaks to plug.
You do not need a CFO to spot the biggest financial leaks, just a closer look. These seven red flags show up over and over in trades businesses making $300K to $8M a year. Check the ones that sound like you.
In a Profit Leak Audit we map these issues to your business using your actual books.
The eight cash-flow mistakes that quietly drain trades businesses:
Slow invoicing
Poor Expense Tracking
Seasonality
Paying vendors too fast
Relying on financing
No tax reserve
Inaccurate job costing and margins
No forecast
The exact fix for each in a PDF field guide you can act on this week.
Your techs cost more than their wage, and a job can look profitable while quietly losing money. Run yours through these two, then use the spreadsheet to give every dollar a job.
Your techs cost far more than their hourly wage. This finds the true loaded cost per billable hour, then the rate you need to charge to hit your target margin.

Estimate only. Uses FICA 7.65% and FUTA 0.6% federal plus your state's typical rate. Confirm your actual workers' comp and state rates against your policy and pay stubs.
Enter what a job actually costs and what you charged. See your true gross margin, checked against healthy trades benchmarks. Pull your loaded labor rate from the calculator above.

Garbage in, garbage out. Misclassified expenses give you wrong margins; wrong COGS gives you wrong pricing. Clean books start with three things:
The right account structure
Consistent categorization
A monthly close that verifies it all.
This is the structure behind clean margins, accurate labor efficiency, and a valuation buyers trust. Download the full account-by-account template below and use it as your starting point.
Don't start a close on incomplete data.
The control step most DIY closes skip.
The Pro help steps like depreciation, prepaids, and use-tax accrual, are easy to check off and still get wrong. If any of those are fuzzy, that's exactly what a free Profit Leak Audit is for. Download the working checklist below and run your close against it every month.
This is what your books actually show you: a vendor and an amount, nothing else. Sometimes that is enough. Often it is a trap, and the only honest move is to pull the receipt. Can you tell which is which?
How would you categorize this?
| Purchase | Where it goes |
|---|---|
| Equipment & materials installed on a job | COGS – Job Materials |
| Permits pulled for a job | COGS – Permits |
| Subcontractor on a job | COGS – Subcontractor |
| Field technician wages, taxes, workers' comp | COGS – Direct Labor |
| Merchant & consumer-financing fees | COGS – Merchant / Financing Fees |
| Shop rags, gloves, nitrogen, consumables | COGS – Shop Stock |
| A tool used across many jobs | Small Tools & Equipment (overhead) |
| Truck fuel, repairs, insurance | Vehicle & Truck Expense (overhead) |
| Office paper, ink, postage | Office Supplies (overhead) |
| Dispatch / accounting / office software | Software (overhead) |
| Payroll processing fees (e.g. "ADP FEES") | Payroll Processing Fees (overhead) — not a payroll liability |
| Google Ads, Angi, direct mail, signage | Advertising & Marketing (overhead) |
Note: we book merchant and consumer-financing fees to COGS, not bank charges because they are a direct cost of getting paid on a job, and keeping them in COGS makes your true job margin honest.
These three are the most common way a profitable trades business looks broke on paper. If any are fuzzy, that is exactly what a free Profit Leak Audit untangles.
You don't need to guess what healthy looks like. These are the numbers we check when we review a trades business in the $300K-$8M range. Start with the benchmarks, then carve out the best targets for your mix.
Benchmarks for trades businesses in the $300K-$8M range. Your best targets inside these ranges shift with your mix of service, maintenance, and install. Updated 2026.
Labor burden is the true hourly cost of a field technician once you add payroll taxes, workers' comp, health insurance, retirement, and other benefits on top of their wage, then divide by the hours they can actually bill after holidays, PTO, training, and shop time. For most trades techs the loaded cost runs roughly 1.5 to 1.7 times the nominal hourly wage, so a technician paid $35 an hour often costs $50 to $60 an hour of billable time.
For HVAC, plumbing, and electrical businesses in the $300K to $8M range, a net profit margin of 8 to 18 percent or higher is a healthy target. Under 8 percent usually means you are carrying most of the risk for very little reward, and the fix is typically in pricing, job efficiency, or overhead.
The most common signs are not knowing your margin by job type, paying vendors before collecting from customers, vague catch-all expense categories, skipping your own pay in slow months, and making spending decisions off your bank balance instead of what is already committed. Our free What's Broken in Your Books diagnostic and Cash Flow Leak Scorecard on this page walk you through the specific red flags.
