Do You Need a Broker to Sell Your Business in Adelaide?

Published 4 July 2026 · Osborn Business Advisory

No — not always. A broker earns their commission by finding you a buyer and managing the sale process, but if you already know who you're selling to, or you're comfortable running the process yourself with the right advice at the right points, a private sale can get you the same outcome for a fraction of the cost.

Here's how to work out which situation you're actually in.

What a broker's commission actually buys you

Business brokers in Australia typically charge 5–12% of the final sale price, and for small-to-medium businesses under $1 million that figure usually sits at the higher end — commonly 8–12% — often alongside an upfront marketing retainer, and usually under an exclusive agreement lasting several months to a year or more. On a $500,000 sale, that's commonly $40,000–$50,000 — money that comes straight out of what you walk away with.

What that fee is meant to cover:

If you're selling to a stranger, in a competitive industry, with no existing buyer in mind, that access and process management earns its keep. It's genuinely hard to find and vet buyers cold, and a broker's network solves a real problem.

When you don't need one

The picture changes when you already know your buyer. This happens more often than people expect — a staff member wants to take over, a competitor's approached you directly, a family member is stepping in, or someone in your industry network has already floated interest.

In that situation, the broker's core value — finding a buyer — isn't needed. What you still need is:

That's advisory work, not brokerage — and it's priced completely differently. You're paying for expertise and a process check, not a percentage of your business's value.

The risk with going it alone completely

The honest counterpoint: private sales that fall over usually fall over on the details, not the headline price. The two most common failure points we see are stale or incomplete legal documents (we've actually seen someone try to use a statutory declaration instead of a binding contract — it didn't end well), and missing conditions — GST treatment, lease assignment, what happens if finance falls through. These aren't broker-only problems. They're "nobody checked" problems, and a broker isn't the only way to get them checked.

The Adelaide angle

Adelaide's business community is small enough that a lot of sales do start with an existing relationship — a supplier, a competitor, someone already known to the owner. If that's your situation, paying full broker commission to formalise a deal you've already sourced yourself is often paying for a service you're not using.

The honest bottom line

If you need a buyer found, screened, and managed from a cold start, a broker's commission is a fair trade for a service you can't easily replicate yourself. If you already have your buyer and just need the deal done properly — valued fairly, documented correctly, and checked for the details that sink private sales — that's a different, much cheaper problem to solve.
