Starting Your Own Trade Business

ABN, insurance, quoting, and running a successful trade business in Australia

Starting a trade business is how tradies turn a good wage into real wealth — and how most of them also learn their hardest lessons. The difference between a successful trade business and a failed one is rarely the trade; it is the business: quoting, insurance, cashflow, tax and contracts. In 2026, with work available everywhere, the constraint on trade businesses is not demand — it is the owner's business systems. This guide walks through the steps that turn a qualified tradie into a profitable business owner.

Overview

The numbers first: a successful sole-trader trade business in a capital city grosses $140,000–$150,000+ in 2026, and a business with one or two employees or apprentices can double that. But the failure rate is real — most trade business failures trace back to three causes: underquoting, poor cashflow and missing insurance or licence obligations. The mechanism that separates the winners: they treat the business as a business from day one — registered, insured, contracted and priced for profit — rather than "just doing a few jobs for cash." Every step below exists to avoid one of those three failure causes.

Step 1: Get Your Business Basics Right

Before the first job: register an ABN (free, online, takes 20 minutes — required for invoicing), choose a business structure (sole trader is the simplest and most common start; a company protects personal assets but costs more to run — revisit it once you have employees or significant assets), register a business name if you are not trading under your own name (ASIC, about $44 per year), and open a separate business bank account — mixing personal and business money is the #1 bookkeeping mistake. The mechanism: the ABN is your identity for GST, invoicing and super; everything else hangs off it.

Step 2: Licences & Registrations

Your trade licence (from the state body — NSW Fair Trading, VBA, QBCC, Building and Energy, etc.) is the foundation, but a business needs more. Most states require a contractor's licence or business registration on top of your personal trade licence to legally take on work — NSW, Victoria, Queensland and WA all distinguish between the individual licence and the business licence. If your turnover will exceed $75,000, you must register for GST and add 10 per cent to invoices. In Queensland, QBCC licensing also involves a financial capacity assessment for builders. The mechanism: the licence is what makes your work legal and your insurance valid — working unlicensed is the fastest way to lose everything in a dispute.

Step 3: Insurance

Insurance is not optional, and the correct set for a trade business is: public liability (mandatory for licences — $5–$20 million cover, typically $1,000–$3,000 per year depending on the trade), home warranty insurance (mandatory for residential building work in most states — it protects the homeowner if you disappear), tool and equipment cover, income protection (your income stops if you are injured — the most overlooked policy in the trades), and workers' compensation (mandatory once you employ anyone, including apprentices). The mechanism: insurance is priced on claims history and risk — the tradie who works safely and documents everything pays a fraction of the premium the cowboy pays, and the cowboy usually cannot get cover at all.

Step 4: Quoting & Invoicing

Quoting is where trade businesses are made and broken. The formula that works: materials × 1.1–1.2 (you are not a free courier), labour at your full charge-out rate ($90–$150 per hour — covering your wage, super, insurance, vehicle, tools, admin and quiet weeks, not your hourly wage), plus a margin for unknowns (5–10 per cent), plus GST. Write every quote as a contract: scope of work, exclusions, payment terms and a variation process ("any changes to scope will be quoted before work proceeds"). Invoice by progress payments on anything over a few days of work — materials upfront, stage payments during, final payment on completion. The mechanism: underquoting is not generosity, it is a transfer from your family to the client — and the tradies who price properly never apologise for it.

Step 5: Tax & BAS

The tax calendar runs quarterly: BAS (Business Activity Statement) every three months — GST collected minus GST paid, plus PAYG withholding if you have employees; superannuation for employees quarterly (and for yourself, if you want to retire); and income tax annually. The mechanism that saves the most money: put aside 20–30 per cent of every invoice into a tax account the moment you are paid — the tradies who go broke at tax time are not the ones who earned less, they are the ones who spent the GST. A good bookkeeper ($100–$200 per month) and a trade-specialist accountant pay for themselves many times over.

Pro Tips for Success

The habits of the tradies who make it: contract everything (a verbal job is a dispute waiting to happen); photograph everything (before, during, after — the photos win the arguments); never work for free (quoting is a cost of doing business, but re-quoting the same job twice is a warning sign); pay yourself a wage first (the business's profit is not your income — your wage is); and systemise the boring stuff (invoicing software, cloud backups, a simple CRM — the tradie who runs the admin like a business is the one who scales past one-man-band).
