Writing a Trade Business Plan
A trade business plan isn't a document for a drawer — it's the arithmetic that tells you whether the business works. Here's what to put in one, and the mistakes that make them useless.
Most trade business plans get written for a bank, printed once and never opened again. That's a waste, because the useful part isn't the document — it's finding out, before you commit, whether the numbers actually work. This guide covers the readiness check that comes first, what belongs in the plan, the financial section that lenders actually read, and the mistakes that turn a plan into a filing exercise.

First: are you actually ready?
Before you write anything, answer five questions honestly. If any of them stops you, the answer isn't that you can't start a business — it's that this is the thing to fix first.
- Can you carry a lean stretch? Work out how many weeks of living costs and business costs you can cover with nothing coming in. If the number is two, you're not ready — invoices take longer than that to arrive.
- Do you have the licence you need to contract? Not the licence to do the work — the one that lets a business charge for it. In most trades those are different, and the second takes time to get.
- Do you know what you'll charge? Not what the bloke down the road charges. Your own number, worked out from your own overheads.
- Do you have somewhere for the work to come from? A trade, a phone and an ABN aren't a pipeline. Who are the first ten clients?
- Is the household on board? Long hours, uneven income and Sunday nights doing quotes affect everyone at home, not just you.
None of these are permanent barriers. But writing a plan around a licence you haven't applied for or a savings buffer you don't have is how a plan becomes fiction — and fiction is exactly what makes plans useless.
What belongs in the plan
A trade business plan doesn't need to be long. It needs to be specific. Six sections cover it, and each one should be short enough that you'd actually re-read it in six months.
| Section | What it answers |
|---|---|
| The business | What you do, who for, in what area, under what structure and licence |
| The market | Who else does this locally, what they charge, and why a client would pick you |
| Services and pricing | What you sell, how you price it, and what margin you're aiming for |
| The numbers | Start-up costs, break-even, cash flow forecast, sales forecast |
| Winning work | Where the first clients come from and what you'll spend to reach them |
| Obligations | Licensing, insurance, work health and safety, and who handles the books |
The section people skimp on is the market one, and it's the most useful. Ring three competitors, ask them to quote a job like the ones you'll do, and see what comes back — what they charge, how fast they respond, how the quote reads. That's a morning's work and it's worth more than any amount of guessing about positioning.
The numbers section, which is the whole point
This is the part a lender reads and the part that tells you whether to proceed. Four pieces of arithmetic, none of them complicated.
- Start-up costs. Every dollar you need before you earn one — licence, vehicle, tools, stock, insurance, software, signage. List them as must-have and nice-to-have, then total the must-haves. That's your entry price.
- Your charge-out rate. Target income plus annual overheads, divided by the hours you can genuinely bill, then adjusted for the margin you want. If the resulting rate is well above your local market, that's information — fix the underlying maths rather than dropping the number.
- Break-even. How much work you must complete each month to cover your fixed costs and your own wage. Expressing it as jobs per week rather than dollars per year makes it real.
- Cash flow forecast. Month by month for the first year: money in, money out, and the balance at the end of each month. This is where most trade businesses discover their problem, because the profit and the timing are different things.
- Sales forecast. Honest, and stated as assumptions rather than hopes — jobs per week, average job value, conversion rate on quotes. Being able to show your working matters more than the total.
The cash flow forecast is the one to spend time on. A profitable trade business can still run out of money, because you buy materials in week one and get paid in week six. Our guides to working out your charge-out rate and improving cash flow in a trade business go deeper on both.
The mistakes that make a plan useless
Bad trade business plans fail in predictable ways. Almost all of them come down to writing what you want to be true instead of what is.
- Optimistic billable hours. Assuming you'll bill 38 hours a week is the most common and most expensive error in the document. After travel, quoting, supplier runs and admin, you won't come close.
- Forecasts with no assumptions. "$250,000 in year one" means nothing. "Six jobs a week at an average of $850, converting one quote in three" can be checked, and corrected.
- Nothing about the quiet months. Every trade has a season, weather, or a Christmas shutdown. A plan that assumes twelve identical months isn't a plan.
- No allowance for unpaid and late payment. Some invoices go late and a few never get paid. Building in nothing for that is planning for a world you don't work in.
- Vague goals. "Grow the business" can't be measured or acted on. "Add ten maintenance clients by March" can.
- Choosing a structure without advice. Sole trader versus company affects liability, cost and how you'll be treated by clients and insurers. Talk to an accountant before you register, not after.
- Never opening it again. A plan reviewed every quarter is a management tool. One that lives in a drawer is a form you filled in.
The most valuable line in most trade business plans is the honest chargeable-hours figure, because everything else is calculated from it. If you've never measured where your week actually goes, spend one week logging it before you write the plan. It's usually a shock, and it's the difference between a rate that works and one that doesn't.
Keeping the plan alive
A plan is only useful if reality gets fed back into it. That means the business has to produce numbers you can actually check it against — which is a systems question, not a planning one.
- Review it quarterly, not annually. An hour every three months. What did you assume, what actually happened, what needs changing. That's it.
- Track actuals against your forecast. Jobs per week, average job value, quote conversion, margin per job. Without these the plan is just a document you once wrote.
- Cost every job when it closes. Quoted versus actual, on everything. Six months of that tells you more about your business than the original plan did.
- Update the plan when the business changes. New trade licence, first employee, a new type of work. Each of those changes your numbers and your risks.

Frequently asked questions
Do I really need a business plan for a trade business?
You need the arithmetic — start-up costs, your charge-out rate, break-even and a cash flow forecast — whether or not you write it up formally. A lender will require the document. For your own purposes, the value is finding out before you commit whether the numbers work, and having something to check reality against later.
How long should a trade business plan be?
A few pages. Six short sections covering what you do, the local market, your services and pricing, the numbers, where work comes from and your obligations. Length isn't the point — specificity is. A short plan you re-read every quarter beats a long one you never open.
What's the most common mistake in a trade business plan?
Overstating billable hours. Assuming you'll bill a full week means every other number in the plan is wrong, because your charge-out rate is calculated from it. After travel, quoting, supplier runs and admin, most sole operators bill well under 30 hours a week. Measure it for a week before you write the plan.
Should I set up as a sole trader or a company?
It depends on your liability exposure, what your clients and insurers expect, and your circumstances — which is exactly the kind of question an accountant answers properly and an article can't. Get that advice before you register a structure, because changing it later is more work than choosing right the first time.
