Selling your business is the biggest financial decision most owners ever make. It's also the one they have the least practice at. Most owners only sell once. Many learn what they should have done six months too late.
The deal is half preparation, half execution. Get the preparation right and the execution gets easier. Get the preparation wrong and you lose time, money, and leverage you can't recover.
This piece walks through the mistakes that cost owners money, and what to do instead.
Why selling isn't as simple as it looks
The story sounds clean. Find a buyer, agree on a price, hand over the business. The reality is a high-stakes process with a dozen moving parts and asymmetric information against you.
Buyers do this often. You do it once.
Poor preparation, bad timing, or missing paperwork can cost the deal entirely, or take hundreds of thousands of dollars off the price. Knowing where owners go wrong is the first step to getting it right.
The mistakes that cost owners money
There are seven recurring mistakes. None of them are glamorous. Most of them get worked through months or years before the sale begins.
-
Leaving the preparation too late. Buyers don't just look at this year's profit. They want a clean track record, strong systems, and a clear path forward. That takes 12 to 24 months to build. Sales planned in the final months rarely produce the same number as sales planned 18 months out. Time the exit around strong performance, not when you're ready to step away.
-
Messy financials. If the books are messy, buyers assume the business is too. They'll either price the risk in with a lower offer, or pass. Keep the numbers clean and current, and have your accountant verify the position. Where it's possible, a formal review or audit lifts buyer confidence and the price along with it.
-
Overvaluing the business. Every owner thinks the business is worth more than it is. Buyers don't care how hard you worked. They care about the commercial return. Get a third-party valuation, benchmark against comparable sales, and stay realistic. Realistic numbers move deals faster and keep negotiations grounded.

-
Unresolved legal issues. Buyers want certainty. Anything that reads as risk to a buyer drags the price down or ends the deal entirely: weakly drafted contracts, compliance gaps, unclear ownership of IP. Run a legal audit with your lawyer before going to market. Tidy contracts, employment agreements, and outstanding compliance items before a buyer's lawyer finds them first.
-
Poor tax planning. You can make a great sale and still walk away with less than you should because of tax. Most owners don't structure the deal properly and pay for it. Get tax advice before you start negotiating. Consider earn-outs, asset versus share sales, staged payments, and timing across financial years if any of those improve the position.
-
Wasting time on unqualified buyers. Tyre-kickers cost time and stall momentum. You don't want to find out someone can't actually fund the deal after you've already shared everything. Qualify buyers upfront: are they serious, do they have the money, do they understand your industry? A good broker or corporate advisor filters the unqualified from the serious.
-
Trying to sell without the right team. A business sale takes more than emails and an introduction. It's a detailed, emotionally charged process with a lot of moving parts. Going it alone usually leaves money on the table. Sometimes it costs the whole deal. The minimum team: a broker (or corporate advisor for larger deals), an accountant, and a lawyer. They handle the negotiation, the due diligence, and the discipline that keeps the deal on track.
What buyers actually want
Avoiding mistakes is half the work. The other half is positioning the business so the next owner can see what they're buying.
- Align with buyer intent. What are they really after: market access, recurring revenue, operational efficiency, IP, team depth? Make it obvious how the business delivers what they value.
- Show the next chapter. Don't sell only what the business is. Sell what's next. The new owner needs a clear path to grow what they've bought. Show that path before they have to.
- Get lean before you list. Tighten operations. Remove yourself from the daily running. A business that runs without the owner is worth more than one that depends on the owner. See How to value a business in Australia for which value levers matter most.
- Have a transition plan ready. Buyers want to know the handover will be smooth. Build the plan before they ask: staff training, customer continuity, key supplier relationships, knowledge transfer. The plan is part of the offering, not an afterthought.
A few questions owners ask early on
Three come up in almost every first conversation.
How long does the sale take? Anywhere from six months to two years, depending on the business, the market, and how prepared you are.
When's the best time to sell? When the business is profitable, growing, and the financials are clean. The worst time is when you're desperate or declining.
Do I need a broker? Yes, if maximum value and a clean process matter. Good brokers earn their fee by driving competition between buyers and handling the negotiation while keeping emotion separate.
A starting point
Selling well is half preparation, half execution. The earlier the preparation starts, the more value the execution captures.
If you're thinking about selling in the next 12 to 24 months, the work to start now is the work that pays the most. Cleaning up financials, tightening operations, sorting tax structure, scoping a realistic valuation. All of it compounds.
That's the work the exit and succession service covers as standard: getting the business sale-ready and protecting what you've built when the right buyer arrives.
The earlier the work starts, the more value the sale captures.
