Do I need a business broker to sell my business?

No. In Australia only a person acting as your agent needs a licence — you can sell your own business yourself. Whether you should is a different question: brokers typically charge commission of roughly 5–15% of the sale price, often with a minimum of $15,000–$30,000, and they earn that when the sale must stay confidential, when the buyer has to be found rather than advertised to, or when you would otherwise negotiate alone against someone who does this for a living. A simple business with a buyer already in view is the case where selling privately usually makes sense.

No, you do not need a business broker. In Australia the licensing rules apply to the person acting as your agent, not to you selling your own business. Whether you should use one is a separate question, and it has a real answer that depends on your business, your buyer pool and how much of the work you can absorb yourself.

Disclosure: bizflip publishes this guide and also sells a self-serve alternative to using a broker. Read it knowing we have an interest in the answer.

The legal position

Selling your own business is not a licensed activity. Acting as someone else's agent is. In NSW you need a real estate agent licence, or a licence restricted to business agent functions, to provide services related to buying or selling a business — including selling, buying, exchanging or disposing of a business or professional practice, or any share or interest in one. Before 23 March 2020 NSW had a separate business agent licence category; those functions now sit inside the real estate agent licence. Queensland works the same way, with a real estate agent licence covering the sale of a business under the Property Occupations Act 2014.

So the licence question only bites when you engage someone. Before you sign with a broker, check their name and licence number on the relevant state register.

What a broker actually does

Business Queensland describes a broker's role as helping with the valuation of your business, promoting and advertising the sale, and negotiating the deal. In practice the work is:

Pricing the business and defending the number to a sceptical buyer.
Preparing the sale documents — an anonymised listing, and a fuller information memorandum for qualified buyers.
Marketing it, including to a buyer database that is not visible to you.
Qualifying enquiries, so you are not handing financials to competitors or tyre-kickers.
Negotiating price, settlement, handover and restraint of trade.
Keeping the deal moving through due diligence, which is where most sales stall.

Business Queensland is direct about the buyer-screening part: not many people feel comfortable with their ability to assess buyers, so using a business broker or licensed agent is often a good idea. That is the part owners most often underestimate.

When a broker is worth paying for

A broker is worth it when the sale has to stay confidential from staff, customers and competitors; when you do not have the hours to run a sale on top of running the business; when the buyer has to be found rather than advertised to; when you would otherwise be negotiating alone against someone who buys businesses for a living; or when a deal needs someone to keep it alive through due diligence.

Confidentiality. A sale that leaks can cost you staff, customers and suppliers before it completes. Running an anonymised process well is skilled work, and a third party can field enquiries without your name attached to them.
Time. A sale is a second job. If the business's earnings depend on you being in it, time spent selling is money off the price.
A buyer pool that must be found. If the likely buyer is a trade acquirer, an interstate operator or an investor group rather than someone browsing listings, the value is in the outreach and the database, not the advertisement.
Negotiating experience. Buyers negotiate more often than sellers do. A broker who has been through the same objections a hundred times is a genuine counterweight, and the difference on price can exceed the commission.
Deal management. Most sales that fail, fail during due diligence. Somebody has to chase documents, answer objections and hold the parties together, and if that person is you, it is happening while you also run the business.

When selling privately is realistic

You already have the buyer. A family member, an employee, a business partner, your landlord or a competitor who has approached you — there is no buyer to find, so you are paying for introduction work that has already happened.
The business is small and simple. Clean books, few contracts, a modest price and nothing structurally unusual.
You have time and tolerance for the admin. The work does not vanish; it moves to you.
Your industry's buyers search listings themselves. In some trades, buyers actively browse marketplaces, and visibility does most of what marketing needs to do.

Even then, private does not mean unadvised. You will still want an accountant to normalise the earnings and a solicitor for the contract of sale, and those fees are unavoidable either way. How to sell a business without a broker sets out what you take on, and documents needed to sell a business covers what a buyer will ask for regardless of who runs the process.

What it costs

Australian brokers generally work on success-based commission of roughly 5–15% of the sale price, on a sliding scale that falls as the deal size rises. Many agreements also set a minimum commission, commonly reported in the $15,000–$30,000 range, and that minimum is what usually decides the real cost of a small sale: a $25,000 minimum on a $200,000 business is 12.5%, whatever percentage was quoted. Upfront engagement or marketing fees are typically charged separately. Business broker fees in Australia sets out the ranges and the questions to ask.

Run the number on your own expected price before you decide. A 10% commission on a $1.5 million sale and a 12.5% minimum on a $200,000 sale are very different propositions, and the work involved is not proportionally different.

The agreement is where the risk sits

If you do engage a broker, the agency agreement matters more than the headline rate. An exclusive agency entitles the agent to commission if the business sells during the term, no matter who found the buyer — including a buyer you found. A sole agency exempts you if you found the buyer yourself. An open listing lets more than one agent, or you, bring a buyer.

Check the term, whether it auto-renews unless you cancel in writing, and whether there is a protection period after it ends during which you would still owe commission on a buyer the broker introduced. There are also formal requirements: in NSW an agent is not entitled to any commission or expenses unless a written agency agreement has been entered into, signed by the client, and a copy served on the client within 48 hours after signing. The Australian Institute of Business Brokers requires its members to be clear about fees, disclose additional costs and obtain written client instructions before starting work — a reasonable baseline whether or not your broker is a member.

It is not all-or-nothing

The choice is often framed as broker or no broker, and it is really a set of separable jobs. You can list the business yourself and pay an accountant for the earnings work and a solicitor for the contract. You can engage a broker on a shorter initial term and renew only if they perform. On a larger sale you can engage an adviser for negotiation and deal management while doing the marketing yourself. Ask any broker what specifically their fee buys — which platforms, how many buyers contacted directly, who prepares the information memorandum — and compare that with what you would otherwise have to do.

How to decide

Do I already know who is likely to buy this?
How badly would a leak damage the business, and can I run a confidential process myself?
What is the commission in dollars at my realistic price, including any minimum?
Do I have ten to twenty hours a month spare over six to twelve months?
Am I comfortable asking a stranger for proof of funds and then refusing them information?
If the price moved by the amount of the commission, would the broker have paid for themselves?

That last question is the one that settles it. If a broker plausibly moves the price by more than they cost, the fee is not the issue. If they plausibly do not, it is.
