The 3 Numbers Every Owner Should Know Cold (And Most Don't)
I've sat across the table from a lot of business owners over the last 20 years. Trucking companies, HVAC outfits, machine shops, retail stores. And I can tell you the same thing about almost every one of them the first time we meet: they can tell me their revenue for the year without blinking. Ask them one of these three numbers, and you get a pause. A guess. Sometimes a phone call to their bookkeeper.
That pause is expensive. Here's why.
1. Your Gross Margin by Job (Not Just Overall)
Most owners know their overall gross margin — revenue minus cost of goods sold, give or take. What they don't know is which jobs, which services, or which customers are actually making them money.
I've seen shops that were profitable on paper every single year, running two or three job types that lost money every time — engine replacements underpriced against parts inflation, a fleet contract that made sense three years ago but never got adjusted, a service line kept around because "we've always done it," not because it pays.
If you don't know your margin at the job level, you're flying the whole business on an average. Averages hide the losers behind the winners. You end up working harder to protect a number that isn't telling you the truth.
What to do about it: You don't need a fancy system. Start by breaking your revenue into 4-6 categories that match how you actually think about your work — oil changes vs. transmission work vs. fleet contracts, for example — and look at gross margin for each one, every month. It's a spreadsheet, not a science project.
2. Your Break-Even Point — In Dollars and In Days
Ask most owners what their break-even revenue is for the month, and you'll get a shrug. Ask them how many days into the month they typically cross it, and you'll get a blank stare.
This is the number that tells you how much risk you're carrying. If your break-even is on the 22nd of the month, a slow week can wipe out your margin for the whole month. If it's on the 10th, you've got room to breathe, invest, and take a hit without panicking.
Owners who don't know this number tend to make decisions out of fear or out of gut feel — holding onto a bad employee too long, delaying a truck purchase, saying yes to a job they should've said no to — because they don't actually know how much cushion they have.
What to do about it: Take your fixed costs — rent, insurance, base payroll, loan payments — divide by your average gross margin percentage, and you've got your break-even revenue. Track how many working days it takes you to hit it each month. Watch how that number moves over time. It'll tell you more about the health of your business than your bank balance will.
3. Your Cash Conversion Cycle
This is the one that sneaks up on people. It's the gap between when you spend money — on parts, on payroll, on a truck — and when you actually collect the cash for the work that used it.
A business can be growing, profitable on paper, and still run out of cash. That's not a myth — it's the most common way I've seen good businesses get into real trouble. You buy inventory, you pay your techs, you do the job, and then you wait 30, 45, 60 days to get paid — meanwhile you're doing it all again for the next job.
Owners who don't track this number get blindsided. They're profitable and broke at the same time, and they don't understand how that's possible.
What to do about it: Know roughly how many days it takes, on average, from the time you spend a dollar on a job to the time you collect the cash for it. If that number is growing, you need to know why — slower-paying customers, more inventory sitting on the shelf, jobs taking longer to invoice. This number is the early warning system most owners don't have.
None of these three numbers require a finance degree or an expensive system. They require someone sitting down, on purpose, and looking at the business the way a lender or a buyer eventually will.
That's usually where I come in. Not to hand you a report you'll file away — but to help you actually know these numbers cold, so you're making decisions from facts instead of gut feel. Whether you're growing, holding steady, or starting to think about what's next for the business, these three numbers are where that conversation starts.
If you don't know all three off the top of your head right now, that's not a failure — it's just where most owners start. Let's fix that.
