The handover: from signing to the first year
What happens after the contract is signed — client transition, staff, the outgoing owner's role, and the mistakes that cost value in year one.

Signing is the middle, not the end
Value in a professional firm transfers through relationships, not through the share register. The period between signing and the first anniversary is where the price paid is either justified or quietly eroded, which is why both parties should negotiate the handover with the same care as the price.
Agree in writing what the outgoing owner will do, for how long, on what days, for what compensation, and what decisions remain theirs. Vague goodwill arrangements are the most common source of friction after completion.
Telling the team
Staff usually learn shortly before or on completion. The message that works is short and concrete: who the new owner is, why they were chosen, what changes now (usually nothing), and who to ask. Silence after the announcement is what generates rumour.
Employment relationships transfer with their existing terms under Swiss law in an asset transfer, and are simply unaffected in a share deal — but the reassurance still has to be said out loud, individually, in the first days.
Client transition
Sequence the client contacts: the largest and most personal relationships first, in person, with the outgoing owner introducing the successor and staying visibly involved. Smaller accounts can follow by letter or call.
The outgoing owner's endorsement is the asset being transferred. A successor who appears alone, too early, converts a relationship into a decision — and some clients will use the moment to review the mandate.
The first year under new ownership
Resist structural change in the first months. Pricing changes, system migrations and reorganisations all read as disruption while trust is still being earned, and they make any client loss look like the new owner's doing — which matters if an earn-out is running.
Watch three things monthly: client retention against the pre-transaction base, staff turnover, and cash. Debt service on acquisition financing begins immediately, while the benefits of any change you make arrive later.
Closing the loop with the seller
Where part of the price is deferred — vendor loan, earn-out, retained shares — the seller has a continuing interest in the business and a right to defined information. Set the reporting rhythm and the measurement rules at signing.
A short, scheduled review between buyer and seller at three, six and twelve months resolves most disagreements before they become claims under the sale contract.
