Valuing your business before sale: practical guide

Why value your business 12-18 months before sale?

Most SME owners start thinking about valuation only when a potential buyer appears. That's too late. At that point, you're negotiating from a weak position: you have no reference figures, no time to optimize price-driving parameters, and the buyer knows it.

By conducting a valuation 12-18 months before sale, you gain three decisive advantages:

1. Identify value drivers - Valuation reveals what increases or decreases your price: operating margins, key person dependency, customer concentration, debt levels. You have time to improve these factors.
2. Set a realistic floor price - You know the minimum amount you won't go below, avoiding unpleasant surprises during negotiation.
3. Strengthen your credibility - Serious buyers will request documented valuation. Arriving with a structured report (DCF + multiples + scenarios) accelerates due diligence and strengthens your position.

Valuation methods for SME sales

In practice, three approaches are used to value an SME before sale. Professionals cross-reference them systematically to get a reliable range.

The multiples method (comparables)

Apply a sector multiple (EV/EBITDA, EV/Revenue) from recent transactions on similar companies. This is the most intuitive method for owners: "companies in my sector sell for X times their EBITDA."

Limitation: market multiples are averages. Your SME may be worth significantly more (or less) if it has higher growth, strong customer concentration, or significant intangible assets (patents, brand).

The DCF method

The DCF method projects future cash flows and discounts them at the cost of capital. It's the reference method because it incorporates your company's specific trajectory: growth, investments, working capital needs, and sector risk via the WACC.

For a sale, DCF is particularly useful because it models the impact of the owner's departure on future cash flows - a key factor that multiples don't capture.

The asset-based method (adjusted net assets)

This adds the market value of all assets (real estate, equipment, inventory, cash) and subtracts liabilities. Relevant for businesses with significant tangible assets (manufacturing, real estate, trading), it undervalues service businesses whose value lies in expertise and recurring revenue.

The 5 mistakes that lower sale price

After supporting hundreds of owners, transmission advisors identify the same recurring mistakes:

1. Key person dependency - If your business can't operate without you, buyers will apply a 20-40% discount. Solution: delegate key functions, document processes, hire an operations manager at least a year before sale.
2. Customer concentration - A customer representing over 30% of revenue is major risk for buyers. Diversify your customer base before sale.
3. Non-optimized working capital - Excessive working capital needs (long payment terms, dormant inventory) directly reduce available cash and Equity Value. Negotiate payment terms and liquidate obsolete inventory.
4. Personal expenses in the books - Company car, above-market rent to family real estate company, spouse's salary without real role... These inflate costs and reduce adjusted EBITDA. Clean up the books 2-3 years before sale.
5. Poor financial documentation - Sloppy accounting, missing projections, or gaps between claimed and actual figures slow due diligence and erode buyer confidence. Invest in a rigorous accountant.

Typical timeline for SME sale

A well-prepared sale typically follows this timeline:

• M-18 to M-12: initial valuation, identify optimization levers, clean up financials.
• M-12 to M-6: address weak points (customer diversification, hire operations manager, optimize working capital), update valuation.
• M-6 to M-3: prepare information memo, select M&A advisor or broker, identify target buyers.
• M-3 to M0: negotiate, conduct due diligence, draft purchase agreement, closing.

The initial valuation (M-18) doesn't need to be a €10,000 audit. A tool like ValorSME lets you get a structured DCF valuation in minutes, with three scenarios to frame your price range. That's enough to start planning and prioritizing optimization actions.
