Got a business idea? Here's who to actually talk to.

The conversation nobody advertises

There's a strange gap in professional services. When you're sick, you see a GP. When you're sued, you call a lawyer. But when you have a business idea — or you're weighing up an investment property, or your side hustle is suddenly making real money — there's no obvious 'first call'. So most people ask a mate, a Facebook group, or nobody at all.

Here's the thing: the professional whose actual day job is stress-testing ideas with numbers already exists. Accountants — especially those doing business advisory work — spend their days inside the finances of dozens of businesses like the one you're imagining. They've seen what works, what fails, and precisely where the money leaks out. Most offer exactly this kind of session. Almost none of them advertise it, because tax returns are what walk in the door.

This guide maps out who to talk to for what — including what an accountant legally can and can't advise on — so the next time the 2am idea strikes, you know whose calendar to book.

Why an accountant is usually the first call

Before you spend money on a logo, a lease or a single share of anything, an hour with a good accountant covers the questions that actually decide whether an idea works:

• Does it stack up?

  Break-even numbers, realistic margins, pricing, and what you'd need to sell per week to replace your salary. Accountants do this arithmetic daily — and unlike your mates, they'll tell you if the numbers don't work.

• Structure — sole trader, company or trust?

  The structure you pick affects tax, asset protection and what happens if things go wrong or very right. Getting it wrong is expensive to unwind later; getting it right at the start is often the single most valuable thing an accountant does.

• The tax angle on an investment

  Thinking about an investment property, selling shares, or crypto? An accountant can model the tax consequences — negative gearing, CGT timing, deductions, land tax — before you commit, not at tax time when it's too late.

• The boring-but-critical registrations

  ABN, GST (and when the $75k threshold actually bites), PAYG, insurances to ask about — the checklist that turns an idea into a legitimate business without ATO surprises.

• A sounding board with skin in the game

  A good accountant wants you as a client for the next decade, so their incentive is your business surviving. That makes their 'honestly, I wouldn't' worth more than most paid advice.

What an accountant can't tell you — and who can

Accountants are not allowed to recommend specific financial products — which shares to buy, which super fund to use, which insurance policy. In Australia that's licensed financial advice and legally requires an AFSL (Australian Financial Services Licence). A good accountant will draw this line clearly and refer you on rather than wing it — treat that as a green flag, not a brush-off.

So the division of labour looks like this: the accountant covers the business and tax side of a decision; a licensed financial adviser covers investment products and portfolio strategy; a lawyer covers contracts, IP, partnership agreements and disputes; and a mortgage broker covers borrowing capacity and loan structuring. For a lot of decisions you'll want two of them — an accountant for the tax modelling on an investment property, a broker for the loan.

What a session actually costs

Less than you'd think — and dramatically less than the mistakes it prevents. Many accountants offer a free or low-cost initial chat (15–30 minutes) to see if you're a fit. A proper advisory session — an hour or two working through your idea, structure options and a rough financial model — typically runs $150–$450 depending on the firm and city. If it relates to running or setting up a business, the fee is generally tax-deductible.

Compare that with the cost of the alternative: the wrong structure (thousands to restructure later), an ATO surprise at your first BAS, or six months of runway spent on an idea whose numbers never worked. An hour of professional scepticism is the cheapest insurance in business.

How to pick the right accountant for the conversation

Not every accountant does advisory work well — some genuinely are tax-return factories. Three filters do most of the work: look for firms that talk about business advisory (not just compliance), check they're registered with the Tax Practitioners Board (every firm on this directory with a TPB Verified badge has been checked against the live register), and read what actual clients say — reviews from business owners mention the advice, not just the lodgement.

Below are some of the top-rated business advisory firms on the directory right now — or answer five quick questions and we'll match you to accountants who already work with businesses like the one you're imagining.
