8 Mistakes Most Commonly Made by New Business Successors in Germany

A business acquisition rarely fails due to the quality of the company. It almost always fails because of avoidable mistakes in the process—mistakes that repeatedly occur in practice across industries, company sizes, and buyer profiles.

At Viaductus, we see daily how buyers search for companies, make contact, and prepare acquisitions. These eight mistakes appear most frequently.

Mistake 1: Starting the Search Too Late

The most common mistake of all. Many interested parties only begin to search seriously when their personal situation becomes urgent—after resignation, shortly before unemployment benefits expire, or when a business idea is already concrete. At this point, the scope for action is often already severely limited.

A business acquisition typically takes 6 to 12 months from the first serious contact to closing. Those who don’t have this time tend to make poorer decisions under pressure—or accept a company that doesn’t really fit simply because it’s the first available one.

What helps instead: Ideally, start the search 12 to 18 months before the intended acquisition date—even if the goal is not yet fully clear. The search itself sharpens the profile.

Mistake 2: Searching Only on Public Marketplaces

Those who search exclusively on platforms like nexxt-change, DUB, or similar see only a fraction of the market. A significant portion of successions happen discreetly: owners do not want employees, customers, or competitors to learn about a potential sale before a concrete buyer is identified.

The most attractive companies—stable cash flows, loyal workforce, strong customer relationships—are often never publicly listed. They are brokered through tax advisors, chambers of commerce networks, M&A consultants, or direct approaches.

What helps instead: Actively search within your network alongside marketplace searches, register with the Chamber of Commerce and Chamber of Crafts, and directly approach companies if you have a clear industry focus. Searching on a platform like Viaductus, which aggregates over 70 sources, significantly increases market coverage—but this does not fully replace an active network approach.

Mistake 3: Not Questioning the Purchase Price

Many buyers accept the seller’s initial price expectation as a given. This is an expensive mistake. Price expectations from owners selling their life’s work are regularly too high—not out of malice, but because emotional value and market value rarely align.

The rule of thumb in financing practice: a reasonable purchase price is three to five times the sustainable annual profit. If the asking price is significantly higher, it may no longer be financeable based on operating results—which means the bank will not participate.

What helps instead: Commission an independent company valuation or calculate it yourself based on the financial statements of the last three years. The purchase price is always negotiable—and in a buyer’s market, more so than ever.

Mistake 4: Underestimating Due Diligence

Acquiring a company without thorough due diligence is like buying a used car without a safety inspection. Hidden liabilities, ongoing legal disputes, expiring key contracts with customers or suppliers, undocumented agreements with employees—all of these can lead to costly surprises after closing.

Especially with smaller craft businesses and owner-managed service providers, documentation is often incomplete. Not intentionally, but because much has been regulated orally over decades.

What helps instead: Engage a tax advisor and a lawyer for due diligence. The costs—typically between €3,000 and €10,000 depending on company size—are one of the most worthwhile investments in the entire process.

Mistake 5: Not Assessing Owner Dependency

A company can look excellent on paper but still pose a significant risk in practice—if the entire customer base is tied to the owner’s person. If 70 percent of revenue comes from long-standing relationships the owner has built over 35 years, the question is: what remains after the handover?

This risk does not appear in financial statements. It can only be assessed through thorough conversations with the owner, their employees, and—if possible—key customers.

What helps instead: Explicitly ask: “Which of your customers would continue working with a new owner?” and “Which customer relationships depend on you personally?” A supported transition phase of 6 to 12 months is essential when owner dependency is high.

Mistake 6: Clarifying Financing Too Late

Many buyers find a company first and then take care of financing. This causes unnecessary time pressure and can lead to a good opportunity falling through because the bank is too slow.

Those who receive unemployment benefits and want to apply for a start-up grant must do so before closing—not afterward. Missing this deadline means losing claims that cannot be asserted retroactively.

What helps instead: Clarify the financing framework before entering serious negotiations. This means understanding KfW funding programs and guarantee bank options, knowing your equity base, and obtaining a basic commitment from your house bank. This provides negotiation security.

Mistake 7: Changing Too Much Too Quickly in the First Months

New owners regularly underestimate how destabilizing changes can be in the initial phase. Employees who have lost their long-time boss and now face a stranger react especially sensitively to changes—even if the changes are objectively sensible.

An employee who leaves because they don’t trust the new owner often takes implicit knowledge with them that is undocumented and irreplaceable for years. Customers who personally knew the former owner are particularly vulnerable to switching during this phase.

What helps instead: Focus consistently on listening during the first three months. Understand how the company really works before making changes. Small, visible improvements—a new accounting system, a modernized website—build trust without shaking existing structures.

Mistake 8: Not Preparing Your Own Profile

Wanting to take over a company is not enough. Owners choose their successor—that is the crucial difference from a job search. When applying, you are not presenting yourself to an anonymous selection process but to a person who has invested thirty years of their life in this company and decides whether the new owner can be entrusted with their life’s work.

If you cannot convey a convincing picture of yourself, your experience, and your vision for the company in this conversation, you lose—regardless of the offered price.

What helps instead: Prepare a structured buyer profile: Who am I, what do I bring, why this company, what do I want to do with it? This sounds obvious—but in practice, it is rarely well prepared.

Conclusion: Succession Can Be Learned

All eight mistakes have in common that they are avoidable—with preparation, the right timing, and the willingness to seek professional support. Business succession is not a leap into the dark. It is a structured process that successfully takes place tens of thousands of times every year in Germany.

Those who know the most common mistakes make them less often.
