Business Sale: The Critical Points That Determine Success or Failure

Business Sale: The Critical Points That Determine Success or Failure

Many business sales fail not due to lack of buyer interest — they fail because of problems the seller knew about but underestimated. The Due Diligence phase, the SPA negotiation process, and the timing of the sale are the three areas where the most value is either destroyed or preserved. Knowing these pitfalls allows you to avoid them.

The Due Diligence Phase: The Most Critical Moment in the Process

Once a buyer has submitted an indicative offer, the so-called Due Diligence begins — a systematic examination of the company from a financial, legal, tax, commercial, and personnel perspective. For the seller, it feels like an X-ray: nothing remains hidden.

Buyer teams typically examine the following during this phase:

• Financial DD: Quality of revenues, sustainability of EBITDA, working capital fluctuations, off-balance-sheet liabilities
• Legal DD: Contractual relationships, IP ownership rights, ongoing disputes, shareholder structure
• Tax DD: Historical tax risks, audit exposure, transfer pricing
• Commercial DD: Market position, competitive intensity, customer retention, pipeline
• HR DD: Key-person dependency, compensation structure, termination risks

Typical Findings That Reduce Purchase Prices

Across hundreds of transactions, the same problems repeatedly emerge during Due Diligence — leading to purchase price reductions or outright process termination:

• Unclear IP ownership: Was software developed by freelancers? Do the usage rights genuinely belong to the company? Where clarity is lacking, the buyer prices in the risk as a discount.
• Customer concentration risk: If a single customer accounts for more than 30% of revenue, that is a significant red flag. Purchase price reductions or earnout structures are the typical consequence.
• Absence of written contracts: Verbal agreements with key customers or suppliers offer the buyer no security.
• Open legal disputes: Ongoing litigation or impending disputes are priced in as a liability.
• Dependence on the managing director: When the entire network, all customer relationships, and operational know-how are concentrated in a single person, the buyer rightly asks: what exactly am I buying?

Vendor Due Diligence: The Offensive Approach

Experienced sellers and their advisors turn the tables: rather than waiting for the buyer's findings, they commission their own Vendor Due Diligence (VDD). An independent advisory firm examines the company from a buyer's perspective — before the first interested party enters the data room.

The advantage: problems are identified early and can be remedied. The VDD report is then made available to qualified buyers — this accelerates the process, builds trust, and significantly reduces negotiation asymmetry.

Contractual Pitfalls in the SPA: What Counts After the Handshake

The Share Purchase Agreement (SPA) is the central contractual document in a business sale — and one of the most complex legal instruments a business owner will ever sign. The most important pitfalls:

• Representations & Warranties: The seller makes extensive representations about the condition of the company. If a representation subsequently proves to be inaccurate, the seller is liable — often for several years after closing.
• MAC Clauses (Material Adverse Change): These clauses allow the buyer to withdraw from the contract under certain circumstances if the business situation has materially deteriorated between signing and closing.
• Purchase price adjustment mechanisms: Under the Completion Accounts model, the final purchase price is only determined after closing based on actual balance sheet figures — with significant dispute potential. The Locked Box model, by contrast, fixes the price at a historical reference date and is often more advantageous for the seller.

Timing: Why the Moment of Sale Determines Everything

Perhaps the most costly mistake in a business sale is poor timing. Anyone who sells from a position of weakness — because a key customer has walked away, EBITDA is collapsing, or a successor urgently needs to be found — surrenders the decisive negotiating lever: the power of choice.

The optimal time to sell is when EBITDA is at or near an all-time high, the market is receiving positive valuations, and the seller is operating from a position of strength. Those who miss this window and sell under time pressure ultimately accept terms they would never have accepted in a properly prepared process.

A business sale is not an event — it is a process that begins two to three years before the actual transaction. Those who understand this and act accordingly have already set the most important switch in the right direction.
