When you buy something expensive—like a car or a home—you don’t just take the price at face value. You compare, inspect, and evaluate. Buying a small business is no different.
Valuing a business goes beyond a glance at revenue. It’s a complex, high-stakes process that helps you avoid overpaying, negotiate with confidence, and understand the future potential (or risk) of your investment. Here’s how to break down the valuation process so you can buy with confidence.
Choose A Valuation Method
The first part of valuation is determining how you want to measure the business’s worth. There isn’t one way to do it, nor a single correct answer to find. Instead, professionals rely on combinations of three core methods that each paint a different picture of the business’s value.
Income-Based Approaches
These follow the logical path of examining how much money the business makes. Professionals often use one of two income-based approaches, depending on the business type and size.
SDE (Seller’s Discretionary Earnings) is the go-to method for valuing owner-operated businesses. It starts with net profit, then adds back things like the owner’s salary and perks, one-time expenses, and non-cash items (like depreciation). This method is excellent for understanding how much cash you can expect to take home or invest.
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation) is a more standardised metric, especially for larger businesses or those with established management teams. It excludes the owner’s salary and focuses on the business’s operational profitability, making it easier to compare with similar companies.
Market-Based Approach
This method involves comparing similar businesses to see how the one you’re looking at stands up to the competition. Examine the sale prices of businesses in the same industry, size, and region. Comparable Sales (Comps) help ground your valuation in market reality and set price benchmarks. However, it comes with a challenge: comps aren’t always public, so you’ll often rely on data from business brokers, valuation databases, or professional advisors.
When using this method, remember to adjust your price to account for the differences between the business you want to purchase and the comps. Consider variables like revenue growth, the owner’s involvement, assets, and risk profile.
Asset-Based Approach
This method is best for asset-heavy or underperforming businesses where earnings don’t reflect their actual value. Adjustable Net Asset Value adds up the fair market value of all assets—equipment, real estate, inventory—and subtracts liabilities. It’s excellent for asset-heavy companies like manufacturers, but it will severely undervalue service-related businesses by ignoring earnings potential and goodwill.
When putting the maths into practice, you’ll want to calculate figures using one or more of these methods to help triangulate an accurate value. Businesses come in all shapes and sizes, and examining your prospective purchase through different lenses will help you arrive at a reasonable figure.
Apply Valuation Multiples
Once you’ve calculated the normalised earnings using SDE or EBITDA, it’s time to adjust the price with a multiple that reflects what the market pays for similar businesses. The calculation is as simple as multiplying the calculated value by the correct multiple.
For instance, if a business has $300,000 in SDE and a typical multiple in that industry is 2.8×, the estimated value would be $840,000.
The trick is finding the correct multiple. Valuation multiples vary by industry, your earnings calculation method, and other factors like recurring revenue vs one-off sales, rate of revenue growth, customer concentration or diversity, profit margins, and operational inefficiencies. Benchmark your multiple using broker data on comps and industry norms, or platforms like BizBuySell, then calculate the business’s value.
Conduct Due Diligence
Once you’ve run the numbers, it’s time to validate them. Due diligence is your chance to independently verify what the seller is telling you and uncover what they aren’t so that you can refine the assumptions behind your number.
Start by reviewing at least three years of financials, including tax returns, income statements, and cash flow reports. Make sure reported profits match tax filings and assess how revenue, expenses, and working capital fluctuate. Look closely at debt obligations, leases, and one-time revenue spikes that could skew valuation.
On the legal side, confirm the business’s structure and ownership, and review key contracts like leases, supplier agreements, and customer deals to ensure they’re transferable. It’s also essential to check for pending litigation, regulatory issues, or compliance risks. These liabilities can impact both valuation and post-sale operations.
People and processes matter, too. Evaluate staff roles, turnover, and whether the company depends heavily on the current owner. Businesses with documented systems and a strong team in place are generally worth more and easier to transition.
Assessing cybersecurity is increasingly important. Look into how data is stored, protected, and whether there’s a history of breaches or privacy violations. A single data issue can have financial and reputational fallout, especially if customer data is involved.
Lastly, zoom out. Understand the business’s position in its market—its competition, brand reputation, and room for growth. A company with diversified revenue, recurring income, and scalable processes commands a higher multiple and is a safer bet long-term.
Conclusion
Valuing a business isn’t just about the numbers—it’s about knowing exactly what you’re buying.
Start by selecting the proper earnings method (SDE or EBITDA), apply the appropriate market multiple, then validate your findings through due diligence. This process protects you from surprises and puts you in control during negotiations.
But valuation isn’t always straightforward. Every business is different, and even small mistakes can cost big. If you’re serious about buying a business, reach out to a professional business broker. They’ll help you uncover the real value, avoid pitfalls, and close a deal with confidence.
