The first day sets the terms for everything after it. Most of what goes wrong in year one traces back to what people were told, and when.
Start a private conversation with the Acquisition Concierge, already scoped to the first hundred days. Pick a starting point, or describe your situation directly.
The opening period of ownership is spent building or spending credibility, and very little else. Staff are trying to work out what this means for them; customers are deciding whether anything has changed for the worse; suppliers are wondering about payment; and everyone is reading the new owner closely for signals. A good first hundred days is unglamorous: tell people what is happening before they hear it elsewhere, make the invisible operational changes that have to happen, meet the customers who matter, and resist the strong temptation to demonstrate decisiveness by changing things you do not yet understand. The plan should also state explicitly what will not change, because in the absence of that statement people assume everything will.
The ordering is the substance. Getting the sequence wrong is more damaging than getting the timing slightly wrong.
Staff first and in person where possible, then key customers and suppliers, then the wider market. Order matters more than polish.
Payroll, banking, insurance, supplier payments and systems access, the invisible things that cause disproportionate alarm if they slip.
Meeting staff and key customers individually. The most valuable diligence you will do happens after closing.
Who reports to whom, and what is secure. Ambiguity here is what sends good people to recruiters.
Getting the numbers you need in a form you trust. Frequently the first genuine surprise of ownership.
The deliberate ones, chosen from what you have learned rather than from what you assumed in the data room.
How a first-hundred-days plan is built.
Credibility with staff and customers is established quickly and repaired slowly.
People fill silence with the worst plausible version. A specific, public list of what stays the same for twelve months buys more goodwill than any amount of general reassurance, and it is a commitment you can actually keep.
In person where possible, on the day it completes, before anyone hears it elsewhere, and with the outgoing owner present and visibly supportive, which matters more than anything the new owner says. Cover what people actually want to know rather than the strategic rationale: is my job secure, does my pay or my manager change, and who do I go to with questions. Then be available afterward, because the individual conversations in the following days are where retention is genuinely decided.
The concentrated ones, individually and by phone or in person, ideally with the outgoing owner making the introduction. The message that works is continuity plus commitment: the same people are serving you, here is what improves, and here is my direct number. Larger customers may have contractual notification requirements or change-of-control provisions, which should have surfaced during diligence, a customer discovering the sale through the trade press when their contract required notice is a poor start to a relationship you paid for.
Anything customers can see, unless it is actively broken. Brand, pricing, account ownership, service model and product range all carry direct revenue risk and are best understood from inside before being changed. Anything that touches how staff are paid or who they report to also deserves patience unless there is a compelling reason. The exceptions are legal, financial or safety issues, and genuine operational risks, those are addressed immediately regardless of how it feels.
Establish the facts before acting, then work out which of three categories it falls into: an indemnifiable breach under the purchase agreement, an operational problem you now own, or something you knew about and underestimated. The first needs your counsel and attention to notice periods, which are frequently short and easy to miss while you are busy. The second and third need an operating response. What consistently makes it worse is deferring the conversation with the seller past a notice deadline because the working relationship feels more valuable at the time.
