A business sale is not a rational transaction — it is a trial of strength. On one side stands the vendor, handing over the work of a lifetime and expecting a fair price. On the other sits an acquirer who brings professional negotiators to the table, knows every step of the process and understands precisely when pressure is most effective. Those who know the typical tactics can counter them — without jeopardising the deal.
The "Last-Minute Price Chip": When the price drops just before signing
One of the most common and insidious negotiation tactics in M&A is the so-called last-minute price chip. The pattern is invariably the same: the buyer has completed Due Diligence, the letter of intent has been signed, both parties are on the final straight of contract negotiations — and then, often only days before the scheduled signing, the buyer comes forward with a revised offer.
The justifications vary: unexpected risks identified during Due Diligence, a change in market conditions, internal approval caveats. In reality, the buyer is betting on exhaustion. After months of intensive preparation, grinding negotiations and emotional investment, many vendors are willing to accept a worse outcome simply to bring the process to a close. A typical scenario: shortly before signing, the buyer requests a reassessment of the agreed multiple on the grounds that Due Diligence has uncovered new risks. What sounds like a technical argument is often a deliberate tactic — and can mean a difference of several million euros depending on the size of the business. This is not coincidence. This is calculation.
Those who concede at the finishing line pay the highest price of the entire process.
How to push back: keeping alternative parties in reserve
The most effective counterstrategy is structural in nature and must be put in place long before signing: you need an alternative buyer in reserve. A professionally structured sale process does not run with a single interested party — it keeps at least two to three qualified candidates in play for as long as possible.
Once the buyer knows they do not have exclusive access, the last-minute tactic loses its leverage. The vendor's threat to turn to the next party must be credible — and it is only credible if the vendor genuinely has alternatives. In addition, clear exit options should be contractually prepared in advance: what happens if the buyer attempts to renegotiate? What damages claims arise? Those who establish the rules of engagement in writing significantly reduce the scope for surprises.
In practice, this is borne out: through a controlled competitive bidding process involving multiple strategic acquirers, multiples can be consistently and materially increased — with an identical business, identical substance, identical earnings profile. The difference lies in the process.
The exclusivity trap: why you must place time limits
Prospective buyers regularly request an exclusivity agreement before committing significant resources to Due Diligence. This is understandable — and in principle legitimate. The trap, however, lies in the detail: an open-ended or excessively long exclusivity period strips the vendor of their most important lever.
The recommendation is clear: exclusivity of no more than eight to twelve weeks, with defined milestones and automatic expiry without any renewal mechanism. If the buyer artificially delays the Due Diligence process in order to exploit the exclusivity period, the vendor must retain the ability to reopen the process. This mechanism should be defined in the letter of intent — not after the conflict has already arisen.
Earn-out: opportunities and risks for the vendor
The earn-out is a widely used instrument on the buyer side for bridging valuation gaps. The principle: a portion of the purchase price is not paid immediately upon closing, but instead linked to future financial metrics — typically revenue or EBITDA over two to four years post-closing.
For the vendor, this carries material risks. The vendor relinquishes operational control but remains economically dependent on the decisions of the new owner. If the buyer increases overhead costs or changes pricing policy after closing, EBITDA falls — and with it the earn-out proceeds. Without detailed contractual protections (accounting standards, veto rights over material changes, clear definitions of the calculation basis), an earn-out should in principle be treated with considerable caution.
Accept an earn-out only when the upfront element of the purchase price already represents an attractive value in its own right and the earn-out constitutes an upside component — not a bridge to a fair base valuation.
Professional preparation creates negotiating power
The best negotiating strategy does not begin at the negotiating table — it begins twelve months earlier. Complete, well-organised data rooms eliminate the buyer's informational advantage — and with it one of their most important sources of pressure. When Due Diligence uncovers no unresolved contractual arrangements, no balance sheet adjustments and no structural surprises, the factual basis for subsequent price reductions is removed.
In practical terms, this means: audited financial statements for the last three to five years, clean accounting records, documented client contracts, functioning personnel structures and clear IP ownership. Those who have completed this groundwork negotiate from a position of strength — not from the defensive.
Equally critical is the role of an experienced adviser as a buffer between vendor and buyer. When the business owner sits at the table in person, emotional and commercial interests become intertwined in ways that regularly lead to suboptimal outcomes. The adviser negotiates professionally, without personal exposure — keeping the vendor out of situations in which emotions might otherwise gain the upper hand.
