You’ve spent 20 years building it. The phone rings, the work gets done, the customers come back. You assume that when you’re ready to step away, you’ll sell, take the cheque, and move on to whatever comes next.

The numbers say otherwise.

The Exit Planning Institute’s 2025 research found that 70 to 80 per cent of privately held businesses listed for sale fail to transact within 12 months. Of the ones that do attract a buyer and make it to due diligence, around half still fall apart before settlement. That means for every business owner who successfully exits on their terms, three or four don’t.

Sitting behind these numbers is a $3.5 trillion intergenerational wealth transfer that Australia is walking into over the next two decades. Most of that wealth is held in private businesses. And most of those businesses, in their current shape, won’t sell.

The real problem isn’t tax

Most pre-sale conversations focus on the wrong things. Tax structuring. Valuation methodology. Whether to use a broker or list privately. All necessary. None sufficient.

Deals don’t typically fall over on tax. They fall over when a buyer looks under the bonnet and discovers the business doesn’t function without the owner in it. The accountant has done their job. The lawyer has done theirs. But the business itself, the thing that is being sold,  won’t transfer.

The make-or-break factor in a sale isn’t profitability. It’s transferability. A buyer isn’t buying your revenue. They’re buying revenue that will keep flowing after you walk out the door.

What owner dependency actually looks like

In my work with trade and family businesses across NSW and QLD, owner dependency shows up in patterns that owners themselves often don’t see.

A few examples:

• The plumbing business where the owner still prices every quote. Quotes don’t go out without him. Margins live in his head: what to charge for awkward access, which jobs to walk away from, which clients to discount for repeat work. None of it is written down.
• The electrical contractor whose top three commercial clients signed on a handshake with the founder twenty years ago. They’ve never met anyone else in the business. When the founder retires, the relationship retires with him.
• The manufacturer where the owner is the only one who knows the real margin on each product line, which suppliers will flex on payment terms, and which machine settings actually work versus what’s written in the operations manual.

The pattern isn’t industry-specific. In any small-to-mid business, owner dependency takes one of two forms: relationships in the contacts list (customers, suppliers, key staff who chose you, not the company) or knowledge in the head (pricing logic, decision rules, the unwritten how-we-do-things-here).

Most owners have both. Most don’t realise it until a buyer points it out.

What buyers actually see at due diligence

This is where deals collapse. Axial’s 2025 Dead Deal Report, an annual analysis of failed M&A transactions, found that non-financial diligence findings are now the single largest cause of broken letters of intent. Customer concentration. Contract issues. Compliance gaps. Undocumented processes.

None of these are accounting problems. They’re transferability problems.

Put yourself in the buyer’s shoes for a moment. You’re being asked to pay three or four times the business’s annual earnings. You’re borrowing against your house to do it. You walk in, sit down with the owner, and start asking questions:

• “How do you price a quote? “I just know”.
• “What happens if your top customer leaves? “They won’t, we’ve been mates for years”.
• “Who else can run this place? “Well, I’m here most days”.

You’re not buying a business. You’re buying a job, and one where the previous worker is leaving on settlement day, taking the manual with him.

That’s why deals fall through. Not because the numbers don’t work. Because the business doesn’t work without the person selling it.

The three-year fix

The good news is that this is fixable. The bad news: it takes time. You can’t unwind 20 or 30 years of owner dependency in the six months before you want to list.

Three moves, all of which pay off whether you sell or not:

1. Document what’s in your head

If the rules for pricing, supplier negotiation, customer handling, and operational decisions all live between your ears, you can’t sell them. Start writing them down. Not a formal operations manual, that comes later. Just start with the decisions you make in a week and capture the logic behind them. Why did you quote that job at that price? Why do you hold that supplier at arm’s length? Buyers pay for systems. They discount for guesswork.

2. Build a 2IC who can actually run it

Not a foreman. Not a “senior staff member.” A genuine second-in-charge who can run the business for two weeks while you’re unreachable. If you can’t take a fortnight off, phone off, email closed, without things going sideways, you don’t have a business. You have a job with overheads.

This is the single biggest valuation lever most owners ignore. A business that runs without you is worth significantly more than a business that needs you. The buyer’s risk drops, the multiple goes up.

3. De-risk customer concentration

If your top three customers make up more than 40% of revenue, a buyer will either heavily discount your valuation or walk away. The fear is rational – those customers chose you, and a new owner inherits that risk on day one.

Diversifying takes time. Start now. A spread of mid-sized customers is worth more to a buyer than a few large ones, even if the revenue is identical on paper.

The real prize

Most owners treat exit readiness as something to deal with at the end, a project to start eighteen months before listing. By then, it’s too late.

The shift in thinking that matters is this: businesses built to be sold are also businesses worth running. A business that doesn’t need you in it every day is more profitable, more resilient, and frankly more enjoyable to own. You stop being the bottleneck. You stop being the only one who can answer the question. You get your weekends back.

Owner independence isn’t just the precondition for selling. It’s the prize itself. The sale, when it comes, is the bonus.

If you’re planning to step back in the next 5 to ten years, the work starts now. Not the sale process, that comes later. The work of building a business that can actually be transitioned. Get that right, and the sale becomes the easy part.
