Business brokers in Australia typically charge a success fee of 5% to 12% of the final sale price, plus separate upfront marketing and documentation costs ranging from $3,000 to $15,000. For small businesses selling under $1 million, the effective cost often sits higher — most brokers apply minimum commissions of $15,000 to $25,000 regardless of the sale price. That’s the headline number. The full picture is more complicated, and understanding it before you start talking to brokers will save you money and a significant amount of wasted time.
How Business Broker Fees Work in Australia
Business brokers work on a success fee model: they earn their commission when the business sells. The fee is calculated as a percentage of the agreed sale price and paid by the seller at settlement, usually deducted from proceeds before you receive them.
The standard commission range in Australia is 5% to 12% of the sale price. Where you land in that range depends primarily on deal size. The rule of thumb: for every million dollars of sale value, expect to pay 5–8% in broker commission. Below $500,000, that percentage climbs toward 10–12%.
Most brokers also charge upfront fees — called “marketing fees,” “listing fees,” or “preparation fees” — payable before the business goes to market. These cover business profile preparation, photography, copywriting, and advertising on platforms like SEEK Business or Business2sell. Budget $3,000 to $15,000 upfront, depending on the broker and the complexity of the business.
What You’ll Pay at Different Deal Sizes
Commission scales as deal size grows — both as a dollar amount and as a percentage. Here’s how the numbers typically stack up across Australian transactions:
| Business Sale Price | Typical Commission | Minimum Fee | Approximate Total |
|---|---|---|---|
| Under $250,000 | 10–12% | $15,000–$20,000 | $15,000–$30,000 |
| $250,000–$500,000 | 8–10% | $15,000–$20,000 | $20,000–$50,000 |
| $500,000–$1M | 6–8% | $20,000–$25,000 | $30,000–$80,000 |
| $1M–$3M | 4–6% | $25,000–$30,000 | $40,000–$180,000 |
| $3M–$10M | 3–5% | $30,000–$50,000 | $90,000–$500,000 |
| $10M+ | 2–4% | negotiated | varies |
The minimum commission is the number that trips up small business sellers the most. If you’re selling a business worth $200,000 and the broker’s minimum is $20,000, you’re paying 10% before you’ve verified whether the broker has sold a comparable business in your industry (which is more than most sellers check before signing the engagement agreement).
Reddit’s r/AusFinance occasionally hosts threads from sellers who discover their broker’s commission represents 50–60% of the actual profit from the sale — different from 50–60% of the sale price, but alarming enough when you’re netting $40,000 on a $300,000 transaction and writing a $25,000 cheque.
What’s Actually Included in a Broker’s Fee
A standard broker engagement typically covers:
- Pricing guidance and basic valuation commentary
- Preparation of a short business profile or summary document
- Listing on online marketplaces (SEEK Business, Business2sell, similar platforms)
- Fielding buyer enquiries and initial screening
- Coordinating site visits and meetings
- Facilitating heads of agreement and basic transaction management
What’s often not included — and what sellers frequently discover late:
- A formal independent business valuation (brokers value businesses; independent valuers verify them — these are different things)
- Legal costs, which typically run $3,000–$10,000 for the sale agreement and transfer documents
- Accountant fees for due diligence responses and tax structuring
- Preparation of a detailed information memorandum — most brokers produce a business profile, not an IM
- Active outreach to strategic or trade buyers — most brokers list and wait rather than hunt
That last point is the most significant gap. A broker listing your business on SEEK Business is creating an inbound funnel; a corporate advisor proactively identifying and approaching strategic acquirers is running an outbound process. Both can sell your business. They are not the same service.
Business Broker vs Corporate Advisor: A Different Fee Model
For businesses selling above $2 million, corporate advisors often represent better value than a traditional business broker — not necessarily because they charge less, but because the scope of work is materially different and the outcomes tend to justify the cost.
Corporate advisors (boutique advisory firms operating in the Australian SME market) typically structure their fees as:
- A monthly retainer covering deal preparation, process management, and advisory work — usually $5,000 to $12,000 per month over a three to six month engagement
- A success fee on completion, typically 2–4% for transactions in the $2M–$15M range, sometimes structured on a Lehman or modified Lehman formula
Total cost can be comparable to a broker — but the service is not. A broker lists your business; a corporate advisor runs a structured sale process, prepares a full information memorandum, builds and approaches a targeted buyer list, and creates genuine competition between shortlisted acquirers.
I saw a trade services business owner in Perth’s northern suburbs sign with a broker at 7% commission on a business they believed was worth $2.8 million. The broker listed it on SEEK Business and a couple of industry portals, fielded enquiries for eight months, and the owner eventually sold at $2.2 million after two price reductions. The commission came to $154,000. A corporate advisory process — with proper positioning documents, targeted outreach to five or six strategic buyers in the sector, and two competing term sheets — would almost certainly have recovered the price discount and more. The fee might have been similar; the outcome would not have been.
For businesses under $500,000, a broker is typically the right tool. The transactions are simpler, buyers find them through online platforms, and the economics of a full corporate advisory engagement don’t make sense at that scale.
How to Evaluate a Business Broker Before You Sign
The commission percentage is the least useful number to compare. Ask these questions instead:
What’s your minimum commission? This is the actual floor for what you’ll pay regardless of sale price.
What do upfront fees cover? Get a specific list of deliverables, not a description of “marketing support.”
What comparable businesses have you sold in the last 24 months? Industry and size range matter. A broker who has sold three engineering firms is not the same as one who has sold one cafe.
How do you find buyers? Online listings only, or active outreach to their database?
What’s your average sale price relative to initial asking price? Hard to get honestly, but ask. The answer tells you whether they’re pricing to sell quickly or pricing to maximise.
Standard engagement terms to watch: exclusivity periods longer than six months should trigger negotiation, and any upfront fee not tied to specific deliverables is worth pushing back on. When preparing your business for sale, the advisor selection decision is one of the most consequential you’ll make — take more time on it than most owners do.
Is It Worth Paying a Business Broker?
For most business owners selling under $1 million: yes. The process is time-consuming, emotionally loaded, and outside most sellers’ experience. A competent broker who has sold similar businesses will run a cleaner process than you will on your own, and the mistakes you avoid will likely cost more than the commission.
For businesses above $2 million: the question shifts from “broker or no broker” to “corporate advisor or broker.” A broker will find a buyer; a corporate advisor will typically run a process that generates better competition, better terms, and — for the right business — a materially higher price.
For businesses above $10 million: a corporate advisor or investment bank. A broker who lists on SEEK Business is not set up for that transaction.
The 5% you pay a good adviser on a $4 million transaction isn’t the same as the 8% you pay a broker who posts the listing and waits. Match the adviser to the transaction. Most sellers don’t, and they find out why when settlement comes around.
