The five most common mistakes when preparing for a business valuation
Good preparation is half the valuation
Whether for succession planning, a company sale, shareholder changes, restructuring measures or tax-related matters, business valuations play a key role in many important business decisions.
Many companies initially focus on the valuation methodology itself. In practice, however, one thing becomes clear time and again: the quality of a business valuation depends heavily on the quality of the preparation.
Missing information, incomplete financial planning or unrealistic assumptions can not only delay the valuation process but also have a significant impact on the final valuation outcome.
Below, we highlight five common mistakes companies should avoid when preparing for a business valuation.
1. Incomplete financial planning
Future expectations are among the most important value drivers in any business valuation. Yet companies often rely on high-level revenue and earnings forecasts alone, while investments, financing costs, workforce developments or market changes are not sufficiently reflected.
Robust planning should be well documented, internally consistent and based on realistic assumptions. The stronger the planning, the more reliable the valuation.
2. Insufficient documentation
Many relevant pieces of information exist within a business but are not adequately documented. Examples include:
- customer structures
- supplier dependencies
- investment plans
- market analyses
- contractual arrangements
- strategic decisions
When this information is missing, it must be compiled retrospectively during the valuation process. This consumes valuable time, ties up resources and makes it more difficult to understand and substantiate the valuation assumptions.
Overly optimistic forecasts
Business owners and management teams usually know their companies better than any external adviser. At the same time, this close connection to the business can occasionally result in overly optimistic assumptions.
Growth rates, margin developments and market expectations should therefore always be challenged critically. A balanced business valuation is not based on wishful thinking but on plausible and well-supported expectations for the future.
If the underlying assumptions cannot be clearly substantiated, the entire valuation may be called into question, potentially leading to lengthy discussions with banks, buyers or, in contentious situations, even before the courts.
Realistic planning, by contrast, builds confidence and strengthens the credibility of the valuation.
4. Mixing private and business interests
Particularly in family-owned businesses, private and business matters can sometimes become intertwined.
Examples include:
- privately used vehicles within the business
- non-market rental or loan arrangements
- private expenses recorded within the company
- one-off exceptional costs
These factors can distort the company’s true earning capacity and should be adjusted before a valuation is performed. Such adjustments often take time and are best addressed well before any transaction deadlines become pressing.
5. Leaving preparation too late
Perhaps the most common mistake is simply a lack of time.
Many companies only begin gathering relevant information shortly before a transaction, succession process or strategic decision. This creates unnecessary pressure, uncertainty and follow-up questions that could have been resolved much earlier.
A business valuation should not only be prepared once important decisions are imminent. Early planning creates the conditions for a more structured, efficient and reliable process.
The KHS perspective
A high-quality business valuation begins long before the calculations themselves.
Robust planning, comprehensive documentation and early preparation form the basis for meaningful valuation results and well-founded business decisions.
