Almost everything written for business buyers stops at completion. The contract is signed, the money moves, and the keys are yours – congratulations, you own a business. But the stretch that decides whether you keep the value you just paid for is the 90 days that come next, and hardly anyone plans for it. We see buyers pour months into getting the deal done, then walk into day one with no plan for the morning after.
The good news is that the first 90 days reward preparation more than almost any other part of buying a business. Here are the 5 things that decide how they go.
1. Work out what actually transferred, and what did not
Day one feels like you own everything. You may not, at least not automatically. Some customer and supplier contracts may require consents or transfer. Some licences and permits may need to be reapplied for, and that can take weeks. Registrations, insurances and supplier accounts may need to be set up fresh.
The risk is finding out which is which in week six, when a permit has lapsed or a key supplier is treating you as a brand new account with brand new terms. Before completion, you want a simple list: what transferred automatically, what needed consent, and what you have to put in place yourself. Walk in knowing which is which.
2. The team you just inherited
In most deals the people are a large part of what you paid for. You take on their accrued entitlements – leave, long service, the lot – and you take on something less visible, which is their goodwill or their nerves. A change of owner is unsettling, and good people keep their options open when they are unsettled.
The fix is leadership, early. Have a plan for how you will talk to staff from day one, show them where the business is going and their place in it, and give them a reason to stay rather than a reason to wonder.
This is also the moment to think about how you hold the key people for the long run, not just settle them through the change. Incentive plans – short-term incentives, long-term incentives, or equity for the handful of people who really matter – are worth getting onto the list now. It can feel like a lot to take on in the first month, but having someone looking after this detail early is part of protecting what you have just paid for.
3. The mistake that erodes value fastest: changing too quickly
This is the number one mistake we see new owners make. You have spent months analysing the business from the outside, you arrive full of plans, and you start changing things in the first fortnight. Then the long-standing office manager who held every client relationship leaves, and half those relationships go with her.
Let the dust settle. Spend the first weeks watching how the business actually works before you touch it. The things that look inefficient from the outside are sometimes the things holding the value in. You can always make the change in month four. You cannot un-lose the person who walked in week two.
4. The relationships that walk if you ignore them
Clients and suppliers watch a change of ownership closely, and silence makes them nervous. The ones who matter should hear from you early, in the right order, and from a real person – not discover the change when an invoice arrives from a company name they do not recognise. A simple communication plan, sequenced before completion, is the cheapest insurance you can buy against losing those relationships in the first months.
5. Start with the end in mind
It sounds odd to think about selling on the day you buy, but the best owners build the exit plan at the start. Beginning with the end in mind gives you a target to build toward, and it keeps you focused on the things that make a business valuable and saleable rather than just busy.
It also points you at the real job of the first 90 days: protecting what you bought. The contracts, the IP, the key people, the systems – the value you paid for leaks if it is not locked in. This is the point where most buyers move from doing the deal to building the business, and where having a legal team that knows what a buyer looks for, because we act for them every day, earns its keep.
It is also the reason we have built tools to map this out for you. They chart your legal infrastructure across the first year, so the post-completion essentials actually get done in the right order, and the investment you have just made is protected rather than left to leak. On a purchase this size, that is cheap insurance on a big spend.
The first 90 days are where the deal is won or lost
You did the hard part. You found the business, ran the numbers, and got to completion. The mistake is treating that as the finish line when it is the start – and handling the most important 90 days of the whole exercise with no plan.
