Why Most Businesses Are Unsellable (And How to Fix Yours)
There is an uncomfortable truth that founders rarely hear early enough: most businesses are unsellable. Not undervalued, not waiting for the right buyer, not just a bit niche. Genuinely, structurally, unsellable.
I’m Adam J. Graham, and after years of building, selling, and advising on exits, I’ve come to believe that helping a founder see this clearly is the single most valuable thing I can do for them. Because the moment you understand why most businesses can’t be sold, you also understand exactly what to fix to make yours one of the few that can.
The good news is that the fixes are knowable. The better news is that they make the business better even if you never sell. The bad news is that they take longer than most founders want to admit, which is why this post is written for the founder who has time, not the one with a buyer already at the door.
The numbers nobody talks about
In any given year in the UK, the percentage of small and mid-sized businesses listed for sale that actually complete a transaction is somewhere between 20 and 30 per cent. The rest either stay listed, get pulled, or end up wound down. For owner-managed businesses with revenues under £5 million, the success rate is at the lower end of that range.
That number alone should give every founder pause. Listing your business doesn’t make it sellable. Wanting to sell doesn’t make it sellable. Even being profitable doesn’t, on its own, make it sellable.
So what does?
What makes a business sellable
A business is sellable when a credible buyer can look at it and confidently believe three things at once.
First, that the business will continue to generate predictable cash flow after the current owner leaves. Second, that the risks attached to the business are understood, contained, and bearable. Third, that the price they pay can be justified to whoever has to sign the cheque, whether that is an investment committee, a bank, or their own family.
Strip away the spreadsheets and the jargon, and that is the whole game. Predictability, manageable risk, and a defensible price. Almost every reason a business fails to sell can be traced back to a failure on one of those three dimensions.
The five most common reasons businesses are unsellable
Let me walk through the patterns I see again and again.
1. The business is the founder
This is, by a long way, the most common reason. The founder is the rainmaker, the head of sales, the chief problem-solver, the relationship owner, the cultural anchor, and often the unofficial finance director. When the buyer asks what the business looks like without the founder, the honest answer is that there isn’t one.
Buyers do not buy businesses where the entire value walks out the door on completion day. They might buy the founder’s time, on an earn-out, but they will not pay a serious multiple for it. The fix is to systematically extract yourself from operations, document what you do, and build a leadership team that can run the business in your absence. This takes years, not months, which is why founders who start preparing late never quite get there.
2. Customer concentration
If a single customer accounts for more than 20 per cent of revenue, your business is hard to sell. If a single customer accounts for more than 40 per cent, it is almost impossible to sell at a reasonable price. The buyer will model what happens if that customer leaves, and if the answer is that the business cracks, the price reflects that risk.
The same logic applies to supplier concentration, channel concentration, and even key-person concentration on the customer side. Diversifying takes time and discipline. The fix usually involves intentional sales effort across new segments, often at lower margins initially, to broaden the base.
3. Messy financials
Buyers buy clarity. If your books are based on cash accounting when you should be on accruals, if revenue recognition is inconsistent, if there are large unexplained variances between management accounts and statutory accounts, the buyer can’t see the business clearly. And what they can’t see, they don’t trust. And what they don’t trust, they don’t pay for.
The fix is to get on proper accounting software, run monthly management accounts to a real deadline, and have at least three full years of clean, auditable financials in place. If you can afford a quality of earnings review before going to market, do it. The £20,000 it costs is recovered many times over in price defence.
4. No recurring or contracted revenue
A business that has to re-sell itself every quarter is worth far less than a business that wakes up each January with most of its revenue already booked. Recurring revenue, multi-year contracts, framework agreements, retainers, and subscriptions all command higher multiples because they reduce the buyer’s uncertainty.
If your business is project-based or transactional, the fix is to introduce contracted elements wherever possible: maintenance agreements, retainers, support contracts, subscription pricing, framework deals. Even a partial shift from one-off to recurring revenue moves the valuation meaningfully.
5. Undocumented operations
If the way the business runs lives in people’s heads, the buyer is buying a black box. Standard operating procedures, documented workflows, written sales playbooks, codified onboarding processes, all of these add value because they reduce the buyer’s perceived risk of post-completion disruption.
The fix is straightforward but unglamorous. Pick one process a week. Document it. File it in a shared system. Within a year you have a manual for the business. Within two, you have an operating system. Buyers reward this directly.
The deeper issue: building backwards from the buyer
If you read those five reasons closely, you’ll see they share a common root. Each is the consequence of building a business for the founder’s life, not for an eventual buyer’s risk model.
The founder builds around themselves because that is what feels efficient when the business is small. The founder takes the biggest customer because they know the relationship. The founder runs the accounts informally because they don’t have time for the discipline yet. The founder relies on their own memory because writing things down feels like overhead. Every one of these decisions is rational in the moment. Every one of them compounds into unsellability over time.
The mindset shift that fixes a business is what I call building backwards from the buyer. From day one, or from today if you didn’t start that way, ask yourself a different question. Not “what makes this easier for me?” but “what would a buyer of this business in three years’ time need to see?”
Once you ask that question, the right decisions become obvious. You hire the second salesperson sooner. You build the second customer segment earlier. You hire the financial controller you’d been putting off. You document the process before it scales out of control. You step out of the meeting that doesn’t need you.
How long the fixes really take
If you’re sitting on a business that has most of these problems today, the question is how long it takes to turn it around. The honest answer is two to three years for a small business, three to five for a mid-sized one.
That sounds like a long time, and it is. But there is no shortcut. Buyers see through cosmetic changes. They want to see a track record of clean accounts, diversified revenue, documented operations, and a functioning leadership team. The track record itself is what creates the value.
The good news is that founders who start the journey almost always feel the business getting better, not just more sellable. Customers are served more consistently. The team grows up. The founder takes proper holidays for the first time in years. The business stops being a constant emergency.
In other words, the work that makes a business sellable is the same work that makes it a better business to own. That is the part most founders only realise once they’re a year or two into the process. The exit is the goal. The journey is its own reward.
The honest test
If you want a quick test for whether your business is sellable today, ask yourself five questions.
- Can the business run without you for three months without losing customers or revenue?
- Could you lose your largest customer tomorrow and survive financially?
- Would your management accounts and statutory accounts agree to the penny on revenue, gross margin, and EBITDA?
- What percentage of next year’s revenue is already contracted today?
- If you were hit by a bus, could your team continue to operate using documented processes?
If the answers are mostly yes, you have a sellable business. Congratulations. The work is to keep it that way and time the market.
If the answers are mostly no, you have what most founders have: a business that works but isn’t yet sellable. The fix isn’t to give up on the idea of selling. It is to start, this quarter, building backwards from the buyer.
That is the entire game.
