He Thought His Margin Was 27%. He Did Not Have One.

A case study. What one builder changed, in what order, and what it did to his numbers.

He was flat out. Two jobs on site, three small ones beside them to fill the gaps, and the phone going all day.

Then the BAS would land.

He would look at the bank account, think he was fine, and find the money was already spoken for. His word for whether he was profitable at that point: touch and go.

Twelve years in business. A crew of five including his wife on the books and two of his sons on the tools. No website, no social, no logo on the shirts. In the business every day and never once on it.

Seventeen months later he turned over $620,000 in a single quarter, his best ever, and paid a $52,000 BAS without flinching because the money was already sitting in a separate account.

Nothing about his trade changed. He is the same builder he always was. What changed is what he measured and what he said no to.

Where he started, from his own P and L

The work was kitchens, bathrooms, decks and one decent sized renovation. The theory was the one everyone runs: keep a big job going and hang three small ones off the side of it, so the team stays busy and the cash keeps coming.

He was putting 27% markup on his quotes and he thought that was his margin.

It is not. A 27% markup is a 21% margin. (Here is the markup vs margin maths if you have never seen it laid out.) 6% on every job, for twelve years, and nobody had ever sat him down and shown him the difference.

That is the first hole. The second one is bigger.

When his financials came across the table there was no cost of sales section in them. None at all. His $149,000 wages line, site wages included, was sitting in operating expenses. So were his subcontractors. That is how the accountant had set it up years earlier and he had never had a reason to question it.

No cost of sales means no gross profit. No gross profit means no gross margin. So in twelve years of trading there had never been a single number anywhere in his accounts that told him whether a job made money.

Which makes the 21% theoretical as well. Take site wages, the subbies and every hour of his own supervision out of the overheads and put them against the jobs where they belong, and whatever was left was lower than 21%. Nobody could say how much lower. There was nothing to measure it against.

His own supervision and project management time was costed at zero. Not underpriced. Absent.

That is what makes the next number worse than it looks. Net profit came in at about 10%, if that, and those are his words.

But no job he ran ever carried the cost of him running it. So a good part of that 10% was never profit. It was the pay for the supervision and project management he was doing for nothing, landing at the bottom of the page and looking like a result.

Put a proper hourly rate on that time, cost it into the jobs where it belongs, and most of the 10% goes with it. On some jobs all of it.

A business that hands you back your own wage and calls it profit has not made you any money.

On top of that he gave his pricing away. Free quotes into three way tenders, hours of takeoffs on jobs he had a one in three chance of winning. On one he did a full estimate for a returning prospect and found out he had been used as a price check. His read on himself afterwards: don’t do that again, just tell him what it costs.

Turnover the year before: about $930,000. The goal he set at the start was $2 million.

The moment it turned

He sat in a Builders Coach event and heard the numbers explained properly for the first time. His words: mind boggling, what have I been doing.

No crisis, no collapse. A bloke who was good at building sat in a room and found out he had been measuring the wrong thing for twelve years.

What he changed, in order

The order matters more than the list. Every move below only works because the one before it was done first.

The first two are really the same job: financial clarity. Nothing after them counts for anything without it, because every one of those later decisions is made off a number, and until these two are done the numbers are fiction.

1. He moved job wages out of overheads and into cost of sales

A cost of sales section went into the chart of accounts, which had never had one. Site wages and subcontractors came out of operating expenses and went into it, where they belong. His wife’s admin wage stayed in overheads, because that is what it is.

On its own that moved nothing on the bottom line. Not a dollar. Same net profit, same bank balance, same year. All it did was tell him the truth.

But it was the truth about the one number every decision in the business hangs off. For the first time in twelve years he had a gross margin at all. Not a better one. One.

2. Then he fixed the costings, by putting supervision and project management in

Reclassifying tells you what a finished job actually earned. It does not make the next one any more accurate. For that he had to start costing the work nobody had been costing.

His own supervision and project management time went into the build at an hourly rate, against the weeks of the job. Twenty week job, so many hours a week, times the rate, into the cost.

Now every job carries the cost of running it. Which means when he puts another set of hands on, the build pays for them instead of his profit paying for them.

Those two moves together are what lifted his net profit. The first made the margin honest. The second made the costings accurate. Between them he finally had financial clarity, and that is the whole thing. Every decision that follows in this article, what to charge, what to take on, how fast to run it, is one he simply could not make before he could see his own numbers.

And if you are reading this thinking hang on, if I cost my own time in and lift my margin then my prices go up and I stop winning work, that is the right question to ask. It is the objection every builder has, and it is why most of them never make either move.

Here is the answer. The client is not deciding on your margin. They have never seen your margin and they never will. They are deciding whether what they want fits the money they have.

So the margin goes in first, at the number the business actually needs, and then the scope gets managed to fit the budget. That is value management. You are not cutting your price to fit the client. You are shaping the job to fit the client, at your price.

Put the education in front of all of it, so they understand before you even meet why accurate numbers matter and how your process works, and by the time price comes up you are not defending it.

Your margin has never been the thing that decides whether they can afford it. The scope decides that. Once he had hold of that, lifting the margin stopped feeling like a risk and started being a decision.

3. Then he lifted the margin, on a ladder, not in one jump

The starting point was 33% markup, which is a 25% margin. From there the ladder goes to 42% markup for a 30% margin, then 50% markup for a 33% margin.

Four months in, the shift showed up in a single quote. An estimate that had been sitting at about $82,000 got rebuilt from scratch at the higher margin and came out at $101,000. He sent it. The client said yes without blinking.

His own account of the old version of himself: I would have dropped that down. I wouldn’t have been doing 33% anyway, I was doing 27%.

That is a 23% price rise on the same job, and the only thing that changed was that he stopped negotiating with himself before the client got the chance.

4. He started measuring gross profit per week

Then he ran the arithmetic that changed the business.

A bathroom: four weeks, 25% margin, about three to four thousand dollars a week of gross profit. A big architectural renovation: seven to ten thousand a week. Two of those running together is around twenty thousand a week.

The three small jobs were not helping his cash flow. They were consuming the weeks that paid him, and splitting his crew while they did it.

His own summary: when you look at profit per week you’re just like, what was I doing, thinking I was making money doing bathrooms.

He also stopped pricing to a margin percentage. He now sets the price by working backwards from the profit per week the job has to clear, and lifts the margin until it does.

5. He stopped taking small jobs

Under $300,000 is no longer worth doing. Two big jobs at a time, nothing beside them.

The crew noticed before the P and L did. Their line back to him: we get so much more done just from not having those small shitty jobs.

The niche tightened at the same time, into architectural renovations and extensions on heritage and period homes. That is not a marketing decision, it is a sequencing one. Doing the same kind of work repeatedly means you get good at the pre-construction, the value management, the costings and the delivery. Take anything that walks in and you are learning from scratch every job.

6. He stopped quoting for free

He put a price on the front end and said it out loud. $395 for a concept level estimate. $2,000 for a full fixed price quote, half on signing and half on delivery, and it comes off the job if they build with him.

How he explains it to architects: the builders who charge nothing are not accountable to anything. You get a cut and paste of someone else’s job. Once a client has paid you, they know exactly what they are getting and by when.

He also built a document. Twelve to 15 pages: how his process works, what value management is, why accurate numbers matter to the client, and plainly, in writing, that there are no free quotes. He express posts it so it arrives days before he does. By the time he walks into the site visit the client has read why he charges and has had time to sit with it.

His reasoning on why it works: the other two builders coming through did not do that.

Then he went at the architects. He sent a lot of cold emails and got three replies. One was a practice that does not normally look twice at a builder his size. He assumed it was a scam.

He prepared for that meeting properly. A cheat sheet, questions to ask, things to say and things not to say. He role played the conversation with AI about 15 times before he had it for real, then sat in the car and ran through it again.

That architect handed him an $800,000 job on value management instead of a tender. On it he gave the client a genuinely detailed breakdown rather than the thin one page you send when nobody paid you to do it properly. The client thanked him for it. The architect told the client they were lucky the two of them work this way.

Nobody said that to him when he was quoting for free.

7. He went after the weeks

Margin is one lever. Time is the other, and almost nobody prices for it.

His sons do their own plastering and tiling, so the only trades he waits on are plumbers, sparkies, painters and brickies. He put incentives in place so the crew had a reason to hit the date rather than just work through it.

Every hour on every job is tracked to the minute through a clock on, clock off app. When the boys kept forgetting to clock off he solved it in one sentence: forget, and you get paid standard hours even if you did overtime. It has not happened since.

The day got restructured too. Gym at 5. Office from about 6.30. On site at 9.30 rather than 7, because the business development work was being squeezed out by the tools. Tomorrow’s task list goes to the crew at 8 the night before, every night, so nobody rings him in the morning asking what they are doing.

Result on one job: priced at 25%, finished four weeks early, landed just under 40%. Same job, same crew, same price. Four fewer weeks.

And he stopped spending money that was never his

GST comes out of every progress claim the day it lands and goes to its own account. His line: that’s not my money. Profit comes out next, into a second account. Then wages, and the tax provision.

The $52,000 BAS that used to cause real anxiety now gets paid out of an account that was always going to pay it. He does not feel it.

Same discipline on the way out. He is putting an extra $2,000 a month onto a property loan inside his self managed super fund.

Where he is now

Turnover: about $930,000 the year before, about $1.7 million now, tracking to $2.5 million against an original goal of $2 million. Overheads essentially unchanged across the lot.

Best quarter he has ever had: $620,000.

$986,000 of money in on his rolling 12 week cash flow forecast, which he rebuilt with AI and updates weekly rather than by hand.

One locked job running at $11,000 gross profit per week over eight weeks.

A job finished four weeks early at just under 40% against a 25% price.

A licence application through in a week and a half against a quoted 12 to 14 weeks, which unblocks another five month job.

His goal for next year is not a turnover number. It is three jobs running at the same time at about $10,000 profit per week each. Thirty thousand a week.

And the tell that the system is working: for the first time in twelve years he feels anxious about where the next job is coming from. He never felt that when he had no idea what any job was earning him.

The reality

None of this is a construction problem. He could always build.

He left money on the table for twelve years for two reasons that have nothing to do with building. He called a markup a margin, so every quote was 6% short of what he thought it was. And his accounts had no cost of sales line, so the wages, the subbies and every hour of his own supervision sat underneath the jobs instead of inside them, and there was no number on the page to check any of it against. Neither of those is a pricing problem. They are bookkeeping problems that show up as pricing problems, and no amount of quoting harder fixes either one.

Then the second one. Margin tells you what a job earns. It tells you nothing about how long it took to earn it. Rent, wages, insurance, the ute and your own wage all run on the calendar, and they run whether the job is moving or not. Two jobs at 25% are not the same business if one takes ten weeks and the other takes twenty six.

The small jobs were never the cash flow safety net he thought they were. They were the thing quietly eating the weeks that paid him.

And the free quote was never the price of doing business. It was the reason he could not afford to price anything properly.

What it actually took

No new trade. No new market. No extra hours.

He moved the wages where they belonged, costed his own supervision in, lifted the margin on a ladder, measured the right number, stopped taking work that could not clear it, charged for the pricing he was already doing for free, and then went and took weeks out of his own program.

In that order, over seventeen months, while running two jobs at a time with his sons.

The builders who go past you are rarely better builders. They just took control earlier.
