{{first_name}} Every time I ask a construction business owner how business is going, I get one of two answers: "Busy" or "Slammed." And believe me both are based on feelings.
Here's the uncomfortable part no contractor wants to hear, “revenue is the most overrated figure in the construction industry.” It tells you how much work you did but not whether the work was worth doing. I've watched owners grow revenue 40% in a year and finish with less cash than they started with. I am sure we all business owners’ can agree on one thing, growth eats cash for breakfast.
The construction company owners who build something that lasts, whether they pour the concrete, design the building, wire it, or sell the materials that go into it, all share one habit. They know their numbers without opening a spreadsheet. Not because they love accounting, but because these eight numbers are the dashboard of a successful business.
1. Gross profit margin. Know it by job, not blended.
Gross profit is revenue minus the direct cost of the work, i.e. the people, materials, and equipment that produced the job before your office, your truck, and your own salary come out.
Your blended company margin is a comfortable lie. It hides the jobs bleeding you behind the jobs carrying you. We once took a plumbing contractor to market that looked like a steady 12% business on the blended number. Job by job told a different story, two divisions running north of 20% were quietly carrying a third that lost money on almost every contract. The buyer's analyst found it in under a week and used it to knock the price down. The owner had flown that plane for years without ever seeing which engine was on fire.
Pull your three biggest jobs from last quarter and work out the real margin on each. If the spread surprises you, that's the lesson.
2. Backlog. The only number that looks forward.
Backlog is the dollar value of signed work you haven't done yet, measured in months of revenue. Everything else on this list is a rearview mirror. Backlog is the windshield.
Watch which way it's moving. If you're winning less work than you're delivering, your business is already shrinking and you just won't feel it for another quarter or two, and by then you'll be making decisions out of fear. A healthy backlog isn't only comfort; it's a leverage. It's what lets you turn down a bad-margin job instead of taking it because you're nervous about next month.
If you can't say how many months of work you're sitting on right now, that's the thing to fix this week.
3. Cash conversion. Start with how fast you actually get paid.
The simplest way to calculate your cash conversion cycle is Days Sales Outstanding (DSO). Calculate how long it takes on average, between finishing the work and the money landing in your account.
Anyone who has been in the construction industry for over an year will agree, construction has one of the cruelest cash cycles in business. You pay the crew every Friday and collect 75 days later. For many businesses, that holdback is often a six-figure, interest-free loan you handed out without ever deciding to. Profit on paper means nothing if the cash arrives after payroll is due. More owners go under from running out of cash than from running out of profit.
Pull your DSO. Then look at what's sitting unpaid past sixty days. It's almost always bigger than the number in your head.
4. Break-even point. What a job has to beat before it pays you.
This is your fixed cost of running the business. Rent, office staff, software, insurance, your own salary and the monthly revenue you have to clear just to land on zero.
It's the number that explains the cruelest trick in this business, a record year for revenue and a miserable year in the bank, at the same time. It happens to owners who don't know their break-even point, so they bid a little too low, stay busy all year, and wonder where the profit went. Busy and profitable are not the same word.
Break-even point is the revenue you have to hit every month before you make a dollar. Most owners have never written it down. At least you be the one who does.
5. Revenue and gross profit per employee.
Every construction owner should know total revenue and gross profit divided by the number of people on your team.
People are your biggest cost and your biggest lever, which is what makes headcount pride so expensive. Adding bodies that don't move this number isn't growth. The sharpest version is the share of your people's hours you can actually bill.
Work out gross profit per person, then ask whether your last three hires pushed it up or down.
6. Client acquisition cost. What does it costs you to win the work.
This is everything you spend to land a new customer. Marketing, estimating time, the bids you chase and lose; divided by the number of new clients you actually win.
Most owners have never measured it, which is why so many keep pouring money into chasing new customers while the cheapest growth they own is sitting in their existing client list. Winning a brand-new client can sometimes cost five to seven times more than getting more work out of one you already have. I once worked with a mechanical contractor spending hard to chase new bids across the city, while his three largest repeat clients hadn't heard from him in a year. We didn't touch his marketing. We just got him back in front of the people who already trusted him and two of them had work they'd been meaning to hand someone.
Add up what you spent last year to win new work and divide it by the number of new clients you landed. Then ask the harder question, “How much of last year's growth came from clients you already had?”
7. Working capital. The fuel tank for growth.
The textbook version of working capital is receivables plus inventory plus cash, minus what you owe in payables. In plain terms, working capital means, what you'd have left if everything due in the next twelve months came due at once. It's the cash that pays for growth before growth pays you back.
Here's the trap most owners don’t understand, growth burns working capital. Every new job sends materials and labour out the door before a dollar comes back in. Your banker and your bonding company both look hard at this before they back you up. You should look at it before they do.
The quick check you can do is to check your current ratio, “what you own that's liquid against what you owe soon”. If it's tight, fix your collections or ease off the gas before the next big job.
8. Net profit margin. This is the only number that's actually yours.
Net profit is what's left after everything is paid, direct costs, overhead, your salary, taxes, all of it.
We all know Construction margins are thin. It can be low single digits in plenty of cases, which is exactly why the other seven numbers matter so much. A 3% net margin means one badly run job can eat the profit of three good ones.
And this is where an accounting number quietly becomes your retirement. Take a $5M business. The gap between a 3% and an 8% net margin isn't five points on a page, at a 5x multiple, it's the difference between selling the business for roughly $750K or selling it for $2M. Same revenue. Same trucks. Same sign over the door.
Find your true net margin for last year. The honest one, not the hopeful one and decide which of the other seven numbers moves it the most.
Point to remember.
You don't need to become an accountant. You need a dashboard, and this is it. The owners who scale aren't smarter than the ones who stall. They just refuse to fly blind. They know these numbers the way a good foreman knows the build sequence; cold, without looking it up.
So pick the one number you couldn't answer just now without reaching for a spreadsheet. That's not a gap in your knowledge, it's the highest-leverage thing you'll work on all month.
Reply and tell me which one it was. I read every reply and the number the most people admit they can't answer becomes the next issue I will write about.
Build deliberately.
Why am I writing this? I've spent over 20 years working alongside construction and trade business owners across Canada. My firm, N3 Business Advisors Inc., has helped hundreds of contractors buy, grow, value, and sell their businesses. I started my career as a teacher, and that part of me never left. So once a week, I put one lesson in your inbox, for free, to help you build a business that buyers line up for. If this was useful, pass it to one owner who needs it. If it wasn't, reply and tell me what you'd rather read about.
