The Mistakes That Sink Trade Businesses

Trade businesses don't fail for lack of work

Ask a tradie who's just wound up what went wrong and you'll rarely hear that there wasn't enough work. You'll hear that the work never quite turned into money — that every month was busy, every month was tight, and one quiet stretch or one bad debt was enough to end it.

That's because these mistakes are all survivable on a single job. Under-quote by a few hundred dollars, wear it. Invoice a fortnight late, wear it. Do a variation on a nod, wear it. None of them hurt once. All of them compound, and by the time the number is big enough to notice it has been running for two years.

Underpricing, and not knowing you're doing it

Nobody sets out to underprice. It happens because the rate came from somewhere other than your own costs — a mate's number, the quote you lost last month, or what you charged when you started and never revisited.

• Copying someone else's rate. They own their ute outright and work from home; you have finance, a yard and an apprentice. Same trade, completely different number needed.
• Counting the hours you work instead of the hours you can bill. Quoting, travel, supplier runs and invoicing take a fifth to a third of the week before you touch a tool, and the rate has to carry them.
• Never adding up the overheads. Insurance, licence, phone, software, accountant, vehicle, tools. They're paid whether or not you're on a job, so they have to sit inside the rate.
• Confusing markup with margin. Adding 20% to your cost does not leave you a 20% margin, and the gap is thousands a year at any real volume.
• Quoting the job you hope it'll be. The best-case job, with no rain, no access problems and no rework.

The symptom is being busy and broke at the same time, and the fix is arithmetic rather than effort. How to work out your charge-out rate builds the number from your income, your real chargeable hours and your overheads, and finding your break-even point tells you how much work you need before any of it is profit.

Funding the work out of your own pocket

A profitable business can still run out of money, because profit and cash are not the same thing. Profit is what the job made. Cash is whether the money arrived before the bills did. On a job where you buy the materials in week one and get paid in week eight, you are lending your client the materials cost for two months — and if you're running four of those at once, you're funding a small credit business you never agreed to.

• No deposit on jobs with real material cost. Take one, and make it big enough to cover what you have to buy before you start.
• No progress claims on anything long-running. A job that runs a month should bill along the way, not once at the end.
• Supplier terms shorter than your client terms. If you pay the merchant in 30 days and your clients pay in 45, the gap comes out of your account every month.
• No idea what's coming. Money in the bank tells you what already happened. Knowing what's due in and out over the next six weeks is what stops the surprise.

How to improve cash flow in a trade business works through the levers at both ends — deposits, terms, progress claims, and the leaks in between. It's the single highest-value read on this list for a business that's growing.

Billing late, and chasing softly

Invoicing is the least enjoyable hour of the week, so it slides to Sunday night, then to next Sunday night. Every day between finishing the job and sending the invoice is a day added to the front of your payment terms, and it's the cheapest money you'll ever recover — nobody has to agree to it and no client will ever complain that you billed them too promptly.

The chasing is the other half. Most tradies are uncomfortable asking for money they've already earned, so the first reminder goes out at 45 days, apologetically. By then the client has recategorised you as someone who doesn't mind waiting.

1. Invoice the day the job finishes. Ideally before you leave site. The client's memory of the work is at its best right then, and so is their willingness to pay for it.
2. Put terms on the invoice and mean them. A due date, the payment methods, and what happens after. Terms nobody enforces train clients to ignore them.
3. Have a fixed ladder for overdue accounts. A reminder before the due date, a follow-up the day after, then a phone call. Run it the same way every time so it isn't a decision you have to make while you're annoyed.
4. Know when to stop and escalate. There's a point where more polite emails cost you more than the debt is worth. Decide in advance where that point sits.

How to chase an overdue invoice covers the ladder in detail, and how to write a tradie invoice that gets paid covers what has to be on the document so there's nothing to query.

The work you did and never charged for

This is the quietest one, and for a lot of businesses it's the biggest. It isn't theft and it isn't laziness — it's a series of small, reasonable-feeling decisions made in someone's hallway.

• The variation agreed on a nod. "While you're here, can you do the laundry too?" — done, never priced, never on the invoice.
• The scope that was never written down. Nobody can bill for extra work when nobody documented what the original work was.
• An estimate treated as a quote. You give a ballpark, they hear a fixed price, and the difference comes out of your margin rather than theirs.
• Callbacks that aren't warranty. Genuine defects are on you. A client wanting something changed after they signed it off is a new job.
• Free advice that eats the week. Two site visits and three phone calls before a quote is real work, and on a job you don't win it's a straight loss.

The fix isn't confrontation — it's writing things down at the moment they happen. A scope in the quote so both sides know what's included, and a variation confirmed by text before you do the work: "Happy to add the laundry — that's another $X and two days, confirm and I'll get it on." Ten seconds, and it converts an argument later into a line item now.

Quote vs estimate covers which document you should be sending and what each one commits you to, and how to write a scope of work covers the inclusions and exclusions that make a variation obvious to everyone.

Growing on a good month

Growth is where a struggling business gets slowly worse and a healthy one gets suddenly worse. The decision usually gets made at the peak — three busy months, work turned away, so you put someone on. Then the market turns, and the wage doesn't.

Two things make this dangerous rather than merely risky. The first is that a wage is not the cost of an employee: on-costs, vehicle, tools, phone, insurance and your own supervision time all land on top, and the person has to bill enough to carry the lot. The second is that growth consumes cash before it produces any — you pay wages weekly and materials monthly, and get paid on your client's terms.

• Hiring off a peak rather than a trend. Look at twelve months, not three.
• Not knowing what the person has to bill. Work the number out before you advertise, not after they start.
• No cash buffer for the ramp. They cost money from day one and are properly productive some months in.
• Assuming more revenue means more profit. A bigger business with the same thin margin is just a bigger way to lose money.

What your first employee actually costs works the full stack through and lands on the hours they need to bill. And before any of that, should you actually grow? is worth an honest half hour — staying the size you are is a legitimate answer, and for a lot of trade businesses it's the more profitable one.

Everything living in your head

The last one is the one that decides whether the business is an asset or a job with extra paperwork. If the pricing, the client history, the job status and the follow-ups all live in your head, then the business stops when you do — when you're sick, on holiday, or simply having a week too busy to think.

It also caps you. You cannot hand a job to someone else if the only record of what was agreed is a conversation you had. You can't put an admin on if there's nothing for them to work in. And you can't sell the thing at the end, because what a buyer is paying for is a business that runs without the previous owner in it.

• Prices you rebuild from scratch every quote instead of a saved price list.
• Jobs whose status only you know, so every question comes to your phone.
• Photos in your camera roll rather than attached to the job they'd defend.
• Quotes with no follow-up, sitting in a sent folder going cold.
• A handover that would take a fortnight if you couldn't work tomorrow.
