Most business owners have a number in their head. A figure they have arrived at over the years — through conversations at networking events, something they once read about multiples, or a rough calculation based on what they think the business turns over.

That number is usually wrong. Not because the owner is unsophisticated, but because business valuation is widely misunderstood — and the way it is most commonly discussed bears very little relation to what actually happens when a business changes hands.

This article is an attempt to cut through that.

There Is No Single "Right" Number

The most important thing to understand about business valuation is this: a valuation is ultimately what one person is willing to accept and another person is willing to pay. That is it. Everything else — the multiples, the formulas, the spreadsheets — is context for a negotiation, not a definitive answer.

This is not a cynical observation. It is a practical one. Two identical businesses, in the same sector, with the same revenue, can sell for very different amounts depending on who is buying, why they want it, what else is on the market at the time, and how well the sale process is managed.

Understanding this is the starting point for thinking clearly about exit.

HMRC Valuations Are Not Sale Valuations

There is a common confusion between two very different types of valuation, and it is worth being explicit about the difference.

An HMRC valuation is a formal exercise conducted for tax purposes. It applies in specific circumstances — setting up an EMI share option scheme, calculating inheritance tax on a business interest, assessing shares transferred as part of a divorce settlement, or dealing with a capital gains event. HMRC valuations follow defined methodologies: earnings multiples, net asset values, discounted cash flow. They produce a defensible, formulaic figure that satisfies a regulatory requirement.

That number has almost nothing to do with what your business would sell for in an open market.

A sale valuation is an entirely different exercise. It is shaped by commercial reality, not tax rules. What a buyer will pay is driven by their perception of risk, their strategic reasons for wanting your business, the alternatives available to them, how motivated they are, and how motivated you are to sell. The same business can attract very different offers from different buyers — not because the formula changed, but because the buyers are different people with different objectives.

Knowing the difference matters because too many business owners spend time optimising for a formulaic number that a buyer will never actually use.

What Buyers Are Really Looking At

When a serious buyer assesses a business, they are primarily asking one question: how confident am I that the performance I can see will continue after I own it?

Everything they look at is an attempt to answer that question. The financial history tells them whether the business performs consistently or erratically. The management structure tells them whether the business runs without the founder or falls apart without them. The client base tells them whether revenue is concentrated in one or two relationships or spread across many. The contracts and recurring revenue tell them how predictable the future looks.

Risk is the primary driver of price. A business that looks risky — unpredictable finances, founder dependency, concentrated revenue, weak systems — will attract a lower offer, or no offer at all. A business that looks low-risk — clean financials, strong management, diverse revenue, documented processes — will attract a higher one.

The multiple is just a shorthand for how much risk the buyer perceives. Which means the single most powerful thing you can do to influence your eventual sale price is to make the business look and feel like a lower-risk acquisition.

What Actually Influences the Number

While you cannot control what a buyer is willing to pay, you can significantly influence the range within which that conversation happens. The factors that consistently move a business towards a stronger valuation are:

Financial clarity and history. Three to five years of clean, accurate management accounts tells a buyer the business is well-run and that the numbers can be trusted. Patchy or unreliable financial records create doubt — and doubt reduces offers.

Recurring and predictable revenue. Businesses with contracted, subscription, or reliably repeat revenue are valued more highly than those dependent on one-off transactional income. If your revenue renews without you chasing it, it is worth more.

Reduced founder dependency. If the business cannot operate without you, a buyer is not buying a business — they are buying a job, and a risky one at that. Demonstrating that revenue, relationships, and operations are embedded in the business rather than the founder is one of the highest-value things you can do before a sale.

Strong margins with a clear story. Buyers look at margins carefully. A business with improving margins and a clear explanation of why they are where they are is far more attractive than one with declining or unexplained margins.

Clean structure and no surprises. Tax issues, disputed liabilities, poorly documented agreements, and related-party transactions all create friction in due diligence. Clean structure removes obstacles to completion.

The Mistake Most Owners Make

The most common mistake is leaving this work too late. Business owners think about exit when they are ready to exit — and by that point, there is limited time to address the things that would have made the biggest difference to value.

The financial history a buyer will scrutinise covers the last three to five years. That means decisions you make today about your bookkeeping, your management reporting, your pricing, your team structure, and your client base will directly shape what your business looks like to a buyer in 2028 or 2030.

Exit planning is not something you do when you decide to sell. It is something you build into how you run the business — years before you need it.

Where MBS Comes In

We are not business brokers and we do not conduct formal HMRC valuations as a primary service. What we do is help owner-managed businesses build the financial foundation and strategic clarity that makes a strong exit possible.

That means reliable management accounts, clean financial history, margin visibility, and a clear picture of what the business looks like to an outside observer. It also means honest conversations about what a buyer would find if they looked closely today — and what it would take to make that picture stronger.

If you are thinking about exit — even loosely, even years away — the most useful thing you can do is understand where your business currently stands. That is what our Financial Clarity Call is designed to explore.
