Why Your Accountant Can't Value Your Business

Your accountant is probably the most trusted advisor in your business. They know your numbers, your tax structure, and your financial history. So when you’re thinking about selling or raising capital, your first instinct is to ask them: “What’s my business worth?”

The answer you get will be technically competent and almost certainly wrong.

The Problem

Accountants are trained in financial reporting and tax compliance. They can calculate your net asset value, your normalised EBITDA, and your discounted cash flow. What they typically can’t tell you is what a buyer will actually pay.

Business valuation isn’t a calculation — it’s a market exercise. The “right” value is what a willing buyer will pay a willing seller in a competitive process. That number depends on:

— Comparable transactions. What have similar businesses actually sold for recently? Your accountant likely doesn’t have access to deal databases or recent transaction experience.

— Buyer motivation. A strategic buyer who needs your client base to enter a new market will pay more than a financial buyer who’s purely optimising returns. Understanding buyer psychology requires deal experience.

— Deal structure. The headline price is meaningless without understanding the structure — earnouts, vendor financing, rollover equity, deferred consideration. According to Harvard Business Review, deal structure affects the effective purchase price by 15–30% in most SME transactions.

— Market timing. Multiples expand and contract with market cycles, interest rates, and sector trends. An accountant applying a static formula doesn’t capture this.

What Accountants Get Right

To be fair, your accountant provides the essential foundation:

— Clean financial statements — the starting point for any valuation — Normalised EBITDA — identifying add-backs and adjustments — Tax structuring — ensuring the sale proceeds are tax-efficient — Due diligence preparation — financial records that withstand scrutiny

These are necessary but not sufficient for valuation. Your accountant gives you the numerator (EBITDA). The multiple — which is where most of the value variation happens — requires market knowledge.

What a Valuation Expert Adds

Someone who values businesses for a living — an M&A advisor, a PE professional, or a specialist business valuer — brings:

Transaction comparables

Access to databases of recent transactions in your sector and geography. Not public market multiples (which apply to much larger businesses) but actual private company transactions at your scale. According to Corporate Finance Institute, comparable transaction analysis is the most reliable valuation method for private SMEs.

Buyer landscape knowledge

Understanding of who’s actively buying in your space, what they’re paying, and what they’re looking for. This shifts the valuation from theoretical to practical.

Qualitative adjustments

The factors that move the multiple up or down — recurring revenue, key-person risk, customer concentration, operational scalability — are qualitative judgments that require deal experience to calibrate correctly.

Process design

How you run the sale process affects the price you achieve. A competitive process with multiple interested buyers creates tension that drives the price up. A bilateral negotiation with one buyer gives you no leverage. Your accountant doesn’t design sale processes.

The Common Mistakes

When business owners rely solely on their accountant for valuation:

— They use book value. Net asset value is almost always below fair market value for profitable services businesses. Your goodwill, client relationships, and team aren’t on the balance sheet.

— They apply a generic multiple. “I heard businesses like mine sell for 4x.” Which businesses? In which market? With what characteristics? A generic multiple is worse than no multiple because it gives false precision.

— They don’t account for structure. A $2M offer with 50% vendor financing and a 2-year earnout is a very different deal from $1.6M all-cash at closing. Your accountant may not help you evaluate these trade-offs.

— They undervalue operational improvements. An accountant who sees your current EBITDA doesn’t see what it could be after AI automation. A PE buyer does — and that’s what they’re pricing in.

What to Do Instead

1. Start with your accountant — get clean financials and normalised EBITDA
2. Talk to 2–3 people who buy businesses — PE firms, M&A advisors, or experienced entrepreneurs. Get their view on what your business is worth and why
3. Don’t rely on a single number — valuation is a range, not a point. Understand what drives you toward the top or bottom of that range
4. Understand the market — what’s trading, at what multiples, and what buyers are looking for right now
5. Read What Is Your Business Actually Worth? for a complete breakdown of valuation drivers

Your Accountant Is Still Essential

None of this means you should fire your accountant. They’re critical to the process — just not for the valuation itself. Use them for financial preparation, tax structuring, and due diligence support. Use someone with deal experience for the valuation and the sale process.
