Ask most owners what their business is worth and you get a number that traces back to a rule of thumb — "three or four times profit", something a peer sold for, or a figure an accountant mentioned in passing. Ask a buyer, and you get a different answer entirely. A buyer does not value your accounts. They value a stream of earnings they believe will continue after you are gone, and they set the price by applying a multiple to those earnings. The multiple is where almost all the money is decided, and it is set by things your balance sheet never records.
This guide explains how a buyer actually arrives at a business sale valuation: the earnings figure they start from, the multiple they apply, what pushes that multiple up or down, and why most of the value they are paying for sits in intangible assets the accounts do not show. It is written for owners of UK businesses turning over roughly £1m to £100m who are approaching an exit. This is seller-at-exit framing — how a trade or private-equity buyer prices the whole business you are selling. It is a different exercise from valuing a business to raise a funding round, where the number rests on future potential rather than a buyer's willingness to pay today.
The first distinction to fix is the one between price and value, because they are not the same thing and confusing them costs owners money.
Value is an analytical estimate — what the business is worth on a defensible basis, derived from its earnings, its assets and its risk. Price is what a specific buyer, on a specific day, in a specific process, actually agrees to pay. Value sets the anchor; price is where negotiation, competition and deal structure land relative to that anchor.
You cannot negotiate your way to a good price from a weak value. The multiple a buyer offers is a verdict on how much of your business survives without you — and that verdict is formed long before anyone sits down to haggle. Preparation moves value; tactics only move price around it.
Two businesses with identical profit can command very different prices. The one with contracted, recurring revenue, a team that runs it, and registered intellectual property is worth more to a buyer than the one that depends on the founder's personal relationships — even though the profit-and-loss statement looks the same. The difference is not in the numbers a buyer can see. It is in the assets underneath them.
Almost every private-company sale valuation reduces to one equation:
Enterprise value = normalised earnings × multiple.
Enterprise value is the value of the business itself, independent of how it is financed. From it, a buyer subtracts debt and adds cash to reach the equity value — the figure that reaches your bank account. But the number that gets negotiated, the one everything turns on, is enterprise value, and it has just two inputs.
The earnings figure is usually EBITDA — earnings before interest, tax, depreciation and amortisation — because it strips out financing and accounting choices and approximates the cash the business throws off. Smaller businesses are sometimes valued on EBIT or on adjusted net profit, but the principle is identical: a buyer settles on a sustainable earnings number, then multiplies it.
That last figure is the point owners most often miss. On a business earning £2m, moving the multiple from 5x to 6x adds £2m of enterprise value — the same effect as doubling a year's profit, achieved without selling a single extra unit. This is why the multiple, not the earnings, is where a well-prepared seller concentrates. Earnings are largely set by the time you go to market. The multiple is still in play.
| Input | What it is | Who sets it | How much you can move it before sale |
|---|---|---|---|
| Normalised earnings | Sustainable, owner-independent EBITDA | Agreed with the buyer in diligence | Modestly — mostly by trading better and adjusting cleanly |
| The multiple | Turns of earnings the buyer will pay | Set by the buyer's read of risk and quality | Substantially — this is where preparation pays |
The profit in your statutory accounts is almost never the profit a buyer values. Owner-managed businesses are run to be tax-efficient and to suit the owner's life, not to present a clean earnings picture to an acquirer. So a buyer normalises — they rebuild your earnings to show what the business would produce under normal ownership.
Normalisation adds back and strips out a defined set of items:
If you pay yourself above or below a market rate for the role, a buyer adjusts to what it would cost to employ a manager to do your job. The car, the spouse on payroll, the personal expenses run through the business — all get normalised out.
A bad-debt write-off, a legal dispute, a relocation, a grant — anything that will not repeat is stripped so the earnings reflect the ongoing business, not an unusual year.
Charitable giving, sponsorships, an office that suits the owner rather than the business — a buyer removes spend that a new owner would not necessarily continue.
Rent paid to a property you own, purchases from a connected company — these are re-based to market terms so the earnings are not flattered or depressed by arrangements a buyer cannot replicate.
The output is your normalised EBITDA — the base the multiple is applied to, and the single most important financial number in the whole transaction. Get it right and you are paid a multiple on the real earnings power of the business. Get it wrong — leave a genuine add-back on the table, or claim one you cannot evidence — and you either give value away or hand the buyer a reason to distrust everything else you present.
Normalisation is not creative accounting. Every adjustment must be defensible with documentation a buyer's advisers can verify. An add-back you can prove strengthens your position; one you assert but cannot support invites a discount on the whole number. The discipline is evidence, not optimism.
Because the base earnings are multiplied, an error here is amplified. On a 6x multiple, a £100,000 add-back you fail to substantiate is £600,000 of enterprise value lost. This is why the owners who defend their price arrive at the table with a normalised profit-and-loss statement already built — not a claim to be argued, but a reconciled document a buyer can check line by line.
Once a buyer knows how much the business earns, they ask how good those earnings are. Two businesses with the same normalised EBITDA are not worth the same if one earns it from long-dated contracts and the other from a handful of relationships that could evaporate. This assessment is the quality of earnings review, and it is where the multiple is really decided.
Quality of earnings asks a set of hard questions:
Owners routinely over-value headline profit and under-value its quality. A business earning £1.5m from three hundred contracted customers on annual renewals is worth materially more than one earning £1.5m from twelve handshake relationships — regardless of what the statutory accounts say. If your revenue is stickier than it looks on paper, the work before sale is to prove it; if it is lumpier than it looks, that is the risk to fix first.
Quality of earnings is the bridge from the earnings figure to the multiple. And when you follow the questions it asks — recurring, diversified, transferable, owner-independent — you find they are not really financial questions at all. They are questions about assets that never appear on the balance sheet.
Here is the fact that reframes the whole exercise. In a modern private company, roughly nine-tenths of enterprise value is intangible — brand, customer relationships, technology, data, processes, know-how. Yet under UK accounting standards, almost none of it appears on your balance sheet. Internally generated intangibles are not capitalised; they are expensed as they are created. The very assets that determine your multiple are, by design, invisible in your accounts.
This is not an accounting flaw to be fixed — it is a well-established rule. But it has a consequence sellers must understand: the balance sheet a buyer receives systematically understates the value of the business, and the gap is precisely the value you are selling. A buyer knows this. Their diligence is built to find, test and price the intangible assets your accounts omit. The question is whether you have identified and evidenced those assets before they do — or whether you let their advisers set the narrative.
At Opagio we organise these assets through The Opagio 12 — twelve categories of intangible value driver that determine hidden enterprise value. Working through them systematically is how a seller finds the value the accounts miss and pre-empts the risks a buyer will otherwise use to chip the price.
Every one of these assets pushes the multiple in the same direction: the more of your value is documented, owned and transferable, the higher the number a buyer will pay.
| Opagio 12 driver | What a buyer is really pricing | Effect on the multiple |
|---|---|---|
| Brand & Reputation | Whether your name and standing transfer to the new owner | Up when the brand is owned and recognised beyond the founder |
| Customer Capital | Contracted, recurring, low-churn revenue they can underwrite | Up with stickiness; down with concentration |
| Technology & Innovation | Proprietary systems and IP they cannot easily rebuild | Up when owned outright and defensible |
| Human Capital | Whose knowledge walks out the door at completion | Down when critical know-how sits only with the owner |
| Organisational Capital | Documented processes — a business that runs without you | Up when it demonstrably operates without the founder |
| Content & IP | Owned content, trademarks and registered rights | Up when title is clean and registrations are current |
| Ecosystem & Partnerships | Transferable supplier, channel and partner relationships | Up when they survive the change of ownership |
| Switching Costs & Lock-In | How hard it is for customers to leave | Up when lock-in is genuine and evidenced |
The multiple is not a fixed sector figure applied mechanically. A buyer starts from a rough range for your industry and size, then adjusts up or down based on what diligence reveals. The adjustments are largely intangible, and they are largely within your control if you start early enough.
| Moves the multiple up | Moves the multiple down |
|---|---|
| Recurring, contracted revenue | Project revenue that must be re-won each year |
| Diversified customer base | One customer above ~20–25% of revenue |
| Business runs without the owner | Founder holds the key relationships and decisions |
| Documented processes and systems | Knowledge that lives only in people's heads |
| Registered IP with clean title | Unregistered marks, unclear ownership of technology |
| Growing earnings | Flat or declining earnings |
| Clean, cash-backed profit | Earnings that don't convert to cash |
| Strong management team staying on | Business that collapses without the seller |
Two forces sit behind most of this list. The first is founder dependency — the single most common reason a strong-looking business attracts a weak offer. If the business cannot be shown to run without you, the buyer is not acquiring a company; they are acquiring a job, and they price accordingly. The second is evidence — the difference between a claim a buyer must take on trust and a fact they can verify. Both take months to shift, which is why the multiple is won in the year before a sale, not in the final negotiation.
An owner who spent eighteen months distributing customer relationships across a team, documenting the delivery process, and registering the trademarks went to market with a Value Drivers Register showing thirty-one identified assets. When the buyer's diligence questioned whether the revenue was really recurring, the contracts and retention data were already in the data room. The multiple did not just hold — the competitive tension the evidence created pushed it above the initial range.
There is one more step that shapes the deal, and it works in your favour to understand it. Once a price is agreed, an acquiring company does not record it as a single lump. Under the accounting rules for business combinations, the buyer has to spread the purchase price across the individual assets they acquired — the tangible ones and, crucially, the identifiable intangibles: the brand, the customer relationships, the technology, the contracts. Whatever cannot be attributed to a specific asset is booked as goodwill.
This exercise gives you a preview of how a buyer sees the shape of your value — which assets carry the weight, and which are effectively unpriced because you never identified them. It is also why the seller who has already catalogued and valued their intangibles negotiates from a stronger position: the value is itemised and evidenced, not left as an undifferentiated blob the buyer defines on their own terms. For the mechanics of how buyers split the price across assets, see our guide on how buyers allocate the purchase price.
The structure of the payment matters too. Buyers rarely pay the whole price in cash on completion. A portion is often held back as deferred consideration or tied to future performance through an earn-out — which means the headline valuation and the cash you actually realise can differ, and both depend on the evidence you brought to the table. In the UK, whether the deal is a share sale or an asset sale also carries material tax consequences, including for the reliefs available to you as a seller — a choice worth settling well before completion.

Your business is worth a multiple of its normalised earnings — and the multiple is a measure of how much of that earnings power survives without you. The earnings figure is largely set by the time you go to market; the multiple is not. It is moved by the intangible assets your accounts do not show: recurring revenue, a business that runs itself, registered IP, documented processes. Identify and evidence those assets before a buyer's diligence goes looking, and you defend a higher multiple rather than concede one.
