The occasions that genuinely require one are narrow. Selling the business or a share of it. Bringing in a partner or investor. Certain kinds of borrowing where a lender wants security. A divorce, a dispute, or an estate matter. Setting up a shareholders agreement so a future exit has agreed terms. Outside those, a first year business almost never needs a formal valuation.
What is worth understanding is what a buyer is actually paying for, because the answer changes how you build the business. Nobody buys your effort or your intentions. They buy predictable profit, and they discount heavily for anything that makes that profit uncertain or dependent on you personally.
The common methods are worth knowing in outline. A multiple of earnings, where a figure is applied to adjusted annual profit, is the usual approach for a small trading business. Asset based valuation suits businesses whose value sits in equipment or property. Revenue multiples appear where profit is not yet meaningful, mostly in categories buyers already understand. For most small service businesses the earnings multiple is the relevant one.
The multiple itself is where the judgement sits, and it is driven by risk rather than by your industry alone. A business where the owner performs the work, holds the relationships, and knows the processes is worth a low multiple, because the buyer is purchasing a job rather than an asset. The same profit produced by a documented operation with a team and repeat customers earns a considerably higher one.
Adjusted profit is the other half and it catches people out. A buyer normalises the figure by removing owner specific costs and adding back a market rate salary for whoever will do your job. If you have been paying yourself little, the adjusted profit is lower than your accounts suggest rather than higher.
The things that raise a valuation are the same things that make a business stable, which is why this is worth understanding early even with no intention of selling. Documented processes. Revenue that recurs. Customers who are not concentrated in one or two accounts. Contracts rather than handshakes. A business that runs when you are away. Clean records that somebody else can examine without a translation.
Customer concentration deserves particular attention. A business where a third of revenue comes from one client is discounted sharply, because that client leaving is a plausible event with a severe outcome. Diversifying is worth doing on its own merits and it happens to be the single change with the largest effect on what the business is worth.
Records matter more than founders expect. Anybody conducting due diligence works from your accounts, and a business with three years of clean statements is straightforward to evaluate. One reconstructed from bank records and memory raises questions that reduce the price whether or not anything is wrong.
Then build as though somebody will look at it eventually, even if nobody ever does. Every change that makes the business less dependent on you makes it more valuable and easier to run in the meantime, which is the argument for doing it regardless of whether you sell.
Be sceptical of any single figure, particularly one produced by an online calculator. A valuation is a range that depends on who is buying, what they want it for, and what they can see in your records, and a precise number implies a certainty that does not exist.
Start keeping the records a buyer would want long before you need them. Clean accounts, documented processes, and written agreements with customers and suppliers take years to accumulate and cannot be assembled retrospectively.
