Six Months of Handover Often Beat Two Years
Six months or twenty-four: how long you stay in the company after closing comes down to one line in the sale agreement, and that line is usually drafted by the buyer. They ask for a long period because a long period feels safe. The seller agrees, because nobody wants to look eager to leave, and because two years "in a support role" seems a small thing next to the price. This is the fork to settle before you sign: a short, dense transition, or a long, diluted presence. They do not suit the same situations, and the second one costs the seller something that only becomes visible afterwards.
What the length does to the transfer of authority
The handover exists to transfer what no contract can transfer: customer relationships, pricing judgement, knowledge of people, the habits of the house. That transfer has a rhythm of its own, and it is shorter than most people expect when someone has organised it. In the mandates I run, the bulk of relationships and decisions changes hands in the first three months, provided a plan exists. What remains afterwards is a matter of being reachable, not of being present every day.
Past a certain point, the seller's presence stops helping and starts holding things back. As long as you are in the building, the team keeps bringing you the hard questions, customers keep dialling your number, and the buyer, out of courtesy or caution, hesitates to decide against your view. I have written elsewhere about the traps of that cohabitation; the point here is that length is their first cause. A two-year handover does not deliver twice the transfer of a one-year one. It keeps a two-headed authority in place twice as long.
And it costs the seller. Twenty-four months of presence, even part-time, means twenty-four months tied to a company that is no longer yours, without the power to run it, often for less than you used to earn. If an earn-out runs alongside, the situation adds a financial stake, which I covered in the choice between an earn-out with a job attached and a clean exit. Meanwhile, whatever you had planned for afterwards waits.
Seven criteria that set the real length
The right length cannot be read off the size of the company or the nervousness of the buyer. It follows from what actually has to pass from one person to another, and from who is receiving it. The table below is the one I use to raise the question before the letter of intent, while the seller still has a hand on the structure.
| Criterion | Argues for short (3 to 6 months) | Argues for long (12 to 24 months) |
|---|---|---|
| Who takes over | An internal manager or an acquirer from the industry who already knows the trade | Someone from outside the industry, discovering the sector and the organisation at once |
| What customers buy | A product, a process, a capability | A personal relationship with you |
| Where the knowledge lives | In procedures, drawings and files kept up to date | In your head and a few heads close to you |
| The commercial cycle | Short: the buyer sees a full cycle within weeks | Long: annual orders, certifications, strong seasonality |
| The second line | A management team that already runs without you | A team that escalates everything to the owner |
| The price structure | Price paid at closing, standard warranties | A large earn-out or vendor loan tying your money to results |
| Your own plans | A next chapter already under way: board seats, another venture | No plans, and a need to remain useful |
Three right-hand boxes out of seven do not add up to a two-year handover. They point to three pieces of work to do before the sale, or to organise differently during the transition. Almost everything in the right-hand column, apart from the buyer's profile, depends on preparation. A company whose dependence on its owner was reduced two years before going to market arrives at the negotiation with a full left-hand column, and the question of length settles itself.
Shortening it without alarming the buyer
A buyer who asks for twenty-four months does not want twenty-four months. They want the certainty that nothing will slip through. That certainty can be provided by something other than your presence, and that is what to put on the table instead of a flat "six months will do", which would rightly worry them.
First, a written transfer plan attached to the agreement: the list of customers, suppliers, contracts and decisions to hand over, each with a date and a named receiver. A buyer who sees that document understands that a transfer is a sequence of acts, not a span of time. Second, a tapering presence rather than a block: full-time in month one, two days a week for the next two, then available on call. An announced schedule does more for the team's stability than an open-ended, continuous presence. Third, a consulting mandate separate from the sale agreement, with a number of days, a daily rate and an end date, rather than an employment contract that would make you an employee of your former company. Fourth, an extension option: the buyer may request additional days beyond the term, at the same rate, up to an agreed ceiling. That clause gives them the security they were after, and it is rarely used, because three months after closing the new owner wants the house to themselves.
Finally, uncouple the handover from the non-compete clause and from any earn-out. These are three different clocks. Buyers readily add them up into a single request for "presence", when the first protects the customer base, the second adjusts the price, and only the third concerns the transfer. Once they are kept apart, the handover almost always lands below twelve months.
Picture an IT services firm of 25 people, whose founder, 60, sells to a group in the same industry; a constructed case, not a client. The acquirer asks for two years. Customers deal with project managers; the know-how is documented; an operations director runs the place. The only right-hand item is a public framework contract, renewed every spring, which the founder negotiates personally. The answer is four months of tapering presence, a clause bringing him back for the next framework negotiation only, and an option on extra days. The buyer gets what they actually wanted. The seller gets twenty months back.
Who should choose what
A short transition of three to six months suits the seller who has prepared the company, who sells to someone in the trade, whose customers buy a capability rather than a person, and who has plans for what comes next. It also suits the company itself, which is less obvious: the new owner takes authority while the team still expects it from them, not after everyone has grown used to two bosses.
A long transition of twelve months or more is justified in two cases only: a buyer from outside the industry who genuinely needs a full cycle at your side, or critical knowledge that nobody else holds and that there was no time to document. Even then, it should taper, be written down and be paid as a mandate. A long handover agreed because the buyer asked and you did not dare to answer is neither of these. It is another year in a house that is no longer yours, and the question to ask before you sign that line is what you intend to do with it.
