You can’t run a building business off a gut feeling and a full inbox. Being busy tells you nothing about whether you’re making money — plenty of flat-out builders find that out the hard way. The fix isn’t a fancier tool. It’s knowing the handful of numbers that actually tell you how the business is going, and reading them on a rhythm. Here are the eight that matter most.
The short version: the eight numbers are gross margin, net profit, break-even, cash buffer, work in progress, debtor days, pipeline and owner pay. Between them they answer three questions — are you making money, can you survive a quiet patch, and is the business actually paying you? Miss them and you’re driving at night with the headlights off.
1. Gross margin
Gross margin is what’s left from a job after its direct costs, expressed as a percentage of the revenue. Take the job’s revenue, subtract that job’s direct costs — labour, materials, subcontractors and plant — and that gross profit as a share of revenue is your gross margin. It’s the first test of whether your pricing works at all.
Why it matters: gross margin is the pool every overhead and every dollar of profit has to come out of. Healthy direction is a margin high enough to cover your running costs and leave real net profit — and knowing it per job, not just across the year, so you can see which builds actually earned their keep and which quietly bled.
2. Net profit
Net profit is the real scoreboard: what’s left after everything. Revenue minus direct job costs, minus all your overheads, minus a proper market-rate wage for the owner — what remains is net profit. If the only way the business looks profitable is by the owner working for free, it isn’t.
Why it matters: a business can have a healthy gross margin and still make no net profit if overheads are quietly eating the difference. Healthy direction is consistently positive net profit, tracked over time — not one good quarter, but a trend you can rely on.
3. Break-even
Break-even is the point where income exactly covers all your costs — below it you lose money, above it you make it. Expressed as a break-even hourly rate, it’s what one hour has to earn just to keep the lights on before a cent of profit. It’s the floor under every quote.
Why it matters: most builders can’t state their break-even rate, and charging under it is the quietest way to go broke while busy. Healthy direction is simple — know the number, and price every job above it on purpose. (How to price a building job shows how it’s built.)
4. Cash buffer
Your cash buffer is the money actually sitting in the bank, expressed as how long it would keep the business running. It’s your runway — the number of weeks or months you could cover wages, subbies and bills if the work slowed right down. Profit is a theory; cash is what pays this Friday.
Why it matters: plenty of builders fail because they run out of cash, even with profitable jobs on the books — often in the gap between paying suppliers now and getting paid later. ASIC’s insolvency data also lists trading losses among the top causes of failure, so profit matters too, but a business with no cash can’t pay this week’s bills. Healthy direction is a buffer deep enough to absorb a quiet stretch or a slow-paying client without panic, and growing rather than shrinking.
5. Work in progress (WIP)
Work in progress is the value of work you’ve done but haven’t yet claimed or invoiced. It’s the gap between what you’ve physically built on site and what you’ve actually claimed from the client. Money you’ve invoiced but not yet been paid is a different number — that’s debtors (see debtor days below). Let WIP grow and you’re financing your client’s build out of your own pocket.
Why it matters: under-claiming is one of the most common cash leaks in building — the work’s done, the money’s earned, but it’s stuck on site instead of in the bank. Healthy direction is keeping your claims in step with the work completed, so WIP stays low and cash keeps flowing.
6. Debtor days
Debtor days is the average time it takes to actually get paid after you invoice. Invoice on the 1st and get paid on the 20th, and that’s roughly your debtor days — the lag between doing the work and banking the money. The longer it stretches, the harder your cash buffer has to work.
Why it matters: every extra day a client holds your money is a day you’re funding their build. Healthy direction is low and falling — tight payment terms, prompt progress claims, and following up the moment an invoice goes overdue.
7. Pipeline
Pipeline is the value of likely work ahead — quoted jobs, signed contracts and strong prospects. It’s your forward workload: how much confirmed and probable work sits between you and an empty schedule. It tells you what’s coming before it arrives.
Why it matters: too little pipeline and you’re heading for a gap that hits cash months from now; too much and you over-commit and blow out timelines. Healthy direction is enough forward work to keep the crew fed and the schedule sensible — not a mad scramble, not an impossible backlog.
8. Owner pay
Owner pay is the wage the owner actually, reliably takes home — not what’s theoretically left at the end. A real, market-rate salary, paid consistently, treated as a genuine cost of the business. If the owner is the shock absorber that only gets paid when there’s spare, that’s a warning light, not a strategy.
Why it matters: a business that can’t pay its owner a proper wage isn’t a business, it’s a job that’s quietly costing you. Healthy direction is a reliable owner’s salary the numbers are built to support — so the business serves your life, not the other way around.
Where to see them — and what to do next
These numbers only work if you can see them without wrestling a spreadsheet every Sunday night. The goal is one simple, one-page dashboard that pulls them together — the business-level figures from your Xero file, and live margin and work in progress from your job tracking — so you read the result and decide, instead of doing data entry. Then a short weekly rhythm to actually look at it.
Future Builder’s Ultimate Dashboard course builds exactly that one-page view, Trusting Your Xero Files gets the data underneath it clean and trustworthy, and Keys to the Kingdom hands you the templates and systems to run the whole rhythm. Because a decade of dashboards is useless if the data going in is a mess — clean numbers first, then the picture.
The eight numbers tell you the parts. To roll them into a single measure of overall business health — one score you can track over time and benchmark, the way a credit score sums up financial risk — that’s what Future Builder’s platform Alfie does. Alfie turns your numbers and systems into a Prime Score and tells you the one thing to fix next; you can run it at alfie.co. And if these numbers are pointing the wrong way, why good builders go broke is worth the read — because it’s almost never the building.
