The thirty-day test

Here is the question, and it is worth answering honestly before anyone else asks it.

If you were unreachable for thirty days, starting tomorrow, with no handover, what would happen to revenue?

Most owners answer this in one of three ways. Some say it would be fine, which is usually true and occasionally optimistic. Some say it would be rough but survivable. And some, after a pause, say it would be a disaster, and then explain why their situation is unusual.

The third answer is the common one. It is also the single largest factor in what a buyer will pay for a business, and the one that takes longest to change.

What the question is really asking

The test is not about whether the lights stay on. A business can coast for thirty days on momentum alone. Orders in the pipeline get filled, invoices go out, staff turn up.

What a buyer is actually asking is narrower: who decides things.

When a customer wants a price outside the normal range, who says yes. When two jobs collide and one has to slip, who chooses. When a supplier misses, who works out the alternative. When someone good threatens to leave, who handles it. When something genuinely new happens, who decides what the business does about it.

If the honest answer to most of those is “me”, the business has a documentation problem in the same way a hospital has a paperwork problem. It is not wrong, exactly, but it misses what is actually going on.

Why owners consistently underestimate this

Because the dependence was never a decision. It accumulated.

You knew the customers because you won them. You set the prices because in the early years you were the only one who understood the margins. You solved the hard problems because there was nobody else to solve them. Every one of those was the right call at the time, and the aggregate of a decade of right calls is a business that has no working answer to the question of what happens without you.

There is also a quieter reason. Being needed is not unpleasant. Most owners who describe themselves as trapped by their business are also, if you talk to them long enough, somewhat attached to being the person it cannot run without. That is worth noticing, because it affects how quickly the situation actually changes once you decide to change it.

What buyers do about it

They discount, they restructure, or they walk.

The discount is the visible version. The restructure is more common and less obvious: a larger earn-out, a longer transition period, more of the price contingent on the business performing after you leave. Owners often read that as a negotiating tactic. It is usually a straightforward reading of risk. If the buyer believes a meaningful share of the earnings walks out with you, they will not pay for it up front.

A caution on numbers here. There are figures circulating about exactly how much owner dependence costs in valuation terms, and some of them are very large. Published key person discounts are more commonly in the range of a few percent up to around a quarter, and the honest answer is that it varies enormously by business, buyer and deal structure. Anyone quoting you a precise percentage is guessing with more confidence than the evidence supports.

What actually changes it

Four things, roughly in order of how much they move the needle.

Someone else makes decisions, and it is visible. Not a deputy who executes your decisions. Someone with a defined area where they decide, including the right to be wrong occasionally. This is the item that matters most and the one owners resist longest, because the first six months of it are worse than doing it yourself.

The customer relationships are institutional. If the ten largest customers know one other person at the company by name, and that person is in the room for the important conversations, the relationship transfers. If they only know you, it does not.

The knowledge is written down. Pricing logic, supplier terms, the reasons behind the arrangements that look odd from outside. Not a binder nobody opens. The specific things a competent stranger would get wrong.

You actually leave for a while. Two weeks with the phone genuinely off is worth more evidence than any amount of documentation. It also surfaces the real gaps, which are never the ones you expected.

How long it takes

Twelve to eighteen months is realistic for a business that starts genuinely owner-dependent. The constraint is not the documentation, which can be done in a quarter if someone is disciplined about it. The constraint is that a buyer wants to see a track record of someone else deciding, and a track record takes time to accumulate by definition.

Which is the whole argument for starting this two years out rather than at the point of listing. It is the one item on the readiness list where time is not a convenience, it is the input.

Where you actually stand

The thirty-day question is the first item on the Exit Readiness Score, because it predicts more than anything else on the list. The score covers seventeen more, takes about five minutes, needs no financial figures, and ends by naming the two weakest things about your position rather than just handing you a number.
