What Running a Competitive Sale Process With Several Buyers Actually Costs
Running three prospective buyers in parallel instead of one adds, for a Swiss SME valued between five and twenty million francs, something between 15,000 and 60,000 francs in additional fees and two to four extra months on the calendar, before anyone even knows whether the competition between them will actually push the price up. That surcharge breaks down into precise line items, and almost no owner has priced them out before committing to a competitive process.
What multiplying counterparties inflates
A single-buyer process follows one line: one data room, one round of questions, one negotiation. A competitive process multiplies every step by the number of shortlisted candidates, and the added cost is not limited to the advisor's fee for orchestrating the competition.
| Line item | Single-buyer process | Three buyers run in parallel |
|---|---|---|
| M&A advisor or broker fees | Usually success-based, standard rate | Comparable rate, but a negotiating base more favourable to the seller |
| Legal counsel (data room, NDAs, Q&A rounds) | CHF 10,000 to 20,000 | CHF 25,000 to 45,000 |
| Management time (presentations, repeated Q&A) | 3 to 5 cumulative days | 10 to 18 cumulative days |
| Accounting restatement for multiple due diligence rounds | One iteration | Two to three iterations, sometimes simultaneous |
| Risk of information leaking to third parties | Contained to a narrow circle | Multiplied by the number of informed candidates |
The most underestimated line item is management time. Every candidate wants its own management presentation, its own back and forth on the same figures, sometimes its own separate site visit schedule. An owner who expected to spend one day a week on the sale often ends up spending two or three during the cross-questioning phases, which is exactly the burden described in negotiating your own sale without burning out: the load does not get distributed across buyers, it stacks up.
Picture a precision engineering SME with 45 employees, valued around ten million francs, whose owner shortlists three candidates after an initial screening. Each one asks for its own data room access, its own round of questions on margins by customer, and two of them want to visit the workshop separately, two weeks apart. This scenario, hypothetical but representative, shows why the advisory surcharge is almost never the heaviest cost item: it is the owner's attention split across three separate calendars that weighs most on the business during those months.
What the competition buys back in return
Set against that surcharge, the expected benefit is well documented: a buyer who knows it is not the only one rarely softens its terms out of generosity. In the mandates I run, the final price gap between a single-counterparty process and a well-run competitive process most often falls between 5 and 15%, an order of magnitude that comfortably exceeds the advisory surcharge needed to obtain it. The effect is not limited to price either: warranty clauses, payment terms and earn-out length also tend to be negotiated more favourably once a buyer knows a competitor is waiting on the same answer.
The calculation is therefore not purely a matter of fees engaged against expected gain. It also depends on the size of the business: below roughly three to four million francs of valuation, the fixed costs of a competitive process weigh proportionally too heavily to justify themselves against a single, already-identified, serious buyer.
The calendar it stretches, rarely shortens
The common assumption is that a competitive process speeds up a sale, since several tracks move forward at once. In practice, the opposite tends to happen: the calendar aligns itself with the slowest candidate, because no serious seller rules out a buyer before the others have had the same chance to make an offer. A process that would have taken four to six months with a single counterparty comfortably stretches to seven or ten months with three candidates run side by side, between synchronised question rounds and the internal approvals each buyer must secure from its own advisors or investment committee.
That extra time carries a cost that appears on no invoice: keeping operations steady while the owner's attention is split between several counterparties, each with its own confidentiality demands. Confidentiality during a sale gets harder to hold as the informed circle widens: more candidates mean more advisors, bankers and analysts who know a deal is under discussion, even under NDA.
What makes the calculation pay off, or not
A competitive process pays off mainly when a business naturally attracts several distinct buyer profiles, financial, strategic or family office, who do not value the same assets the same way: we detail those differences in financial buyer, strategic buyer, family office. Facing a competitor already identified as the only credible buyer for industrial reasons, staging an artificial competition costs a great deal without changing much about the outcome.
An owner weighing a competitive process is better off asking their advisor for an itemised budget before committing, line by line rather than a single rounded estimate. That upfront costing is what allows an honest comparison between the expected surcharge and the realistic gain range for their own file, sector and company size, rather than leaning on the general promise that competition always favours the seller.
