Price escrow: what it actually protects in a Swiss sale

A price escrow holds back part of the purchase price on a third-party account for a period set in the sale agreement, typically twelve to twenty-four months after signing, to secure the seller's contractual commitments. The money has already changed legal ownership, but it stays out of reach for both sides until the release conditions are met.

What an escrow protects, and for whom

The common picture is a cautious buyer withholding part of the payment just in case. That is not wrong, but it is incomplete. A well-negotiated escrow protects both sides symmetrically, in a way many sellers only discover late in the process.

The seller, as much as the buyer

Without an escrow, a seller's warranty stays a contractual promise: if the buyer later discovers a hidden liability, they must pursue a claim against a seller who, eighteen months after collecting the full price, may already have reinvested or spent the funds. The remedy exists on paper, but it is far slower and less certain in practice. An escrow flips that practical burden: the money is already set aside, and it is the buyer who must justify a claim to access it before the deadline, not the seller who must prove solvency after the fact. For a seller who negotiates well, it becomes a known cap on exposure rather than an open-ended risk stretching over years.

The mechanism, in one transaction

Picture the sale of a logistics company valued at CHF 6 million. The agreement sets a 10% escrow, CHF 600,000, held by a notary for eighteen months. Six months after signing, the buyer discovers that a major client contract, presented as renewable, actually carries a short-notice termination clause nobody flagged during due diligence. The estimated loss in value gets settled by a draw on the escrow, without litigation, because the sale agreement already covered exactly this scenario. Without an escrow, the same dispute would likely have ended up in arbitration, years later.

When an escrow is worth having

An escrow is not a reflex to apply to every deal. It answers an identified risk, not a generic sense of caution.

The signals that call for a substantial escrow

In the mandates I run, three situations almost always call for an escrow beyond a token minimum: accounts that have never been reviewed by an independent auditor, a heavy dependence on one or two clients whose contracts expire shortly after closing, and an ownership structure that changed recently (a buyout of a partner, an exit) without the related clauses being updated elsewhere in the corporate documents. Each signal raises the odds that a liability surfaces after signing rather than before.

The deals where it becomes an unnecessary reflex

By contrast, on an SME with several years of audited accounts, a diversified client base, and a clean due diligence file, an oversized escrow, say 25% of the price over three years, no longer protects much of anything real: it ties up capital the seller could otherwise redeploy, and often signals, on the buyer's side, a negotiation driven by generic caution rather than by an identified risk. Legal due diligence is precisely what separates the two cases before the amount gets fixed.

How to frame it so it holds up

A badly drafted escrow protects nobody, it simply shifts the dispute from a question of substance to a question of form.

Amount and duration

For a Swiss SME, the usual range runs between 5% and 15% of the sale price, over twelve to twenty-four months. A shorter window than twelve months rarely gives a tax liability or a client claim enough time to surface; longer than two years, absent a specific identified risk, ties up the seller's capital without a matching benefit.

The thresholds that keep out the noise

An escrow with no de minimis threshold turns every minor disagreement, a disputed CHF 3,000 invoice, a forgotten warranty claim, into grounds for a freeze. The clause needs a floor amount below which no claim is admissible, and an overall cap beyond which the escrow can no longer be drawn on, even if other warranties in the agreement remain available separately.

Who actually holds the money

The choice of custodian matters more than most parties assume when signing. A Swiss notary or bank offers a neutrality that is hard to dispute; parking the escrow with one of the parties, or with its own counsel, quietly reintroduces the imbalance the mechanism was meant to remove.

An escrow does not replace serious due diligence, it buys back the time you would otherwise need to discover what the due diligence should have caught.

Why some escrows fail

A trigger clause that says nothing

The most common weakness is not the amount, it is the definition of the triggering event. A clause that lets the buyer draw funds "in case of a breach of representations and warranties," without spelling out how notice must be given, how long the seller has to dispute it, or who arbitrates a disagreement, turns the escrow into a grey zone each side reads in its own favor when the moment comes.

The wrong banking partner

Some Swiss banks treat an escrow account like an ordinary deposit, without the tripartite blocking instructions that make it a legally watertight vehicle. The seller then finds out at release time that the account was never locked down as the contract intended, and that access to the funds depends on the institution's goodwill rather than on the agreement.

The tax blind spot

A point few sellers see coming: Swiss tax authorities generally treat the capital gain as realized at closing, on the full price, escrow included, even though part of that money stays out of reach for up to two years. A seller who does not set aside that tax charge from the cash actually received ends up having to fund tax on money they have not collected yet. This is worth checking with a tax adviser before signing, not after, especially when the deal structure combines an escrow with an earn-out: both mechanisms hold back money, but for different reasons, and a tax adviser who conflates the two often computes the wrong liability.
