You are the single point of failure, and that is fixable

Everything routes through one place

A very small business concentrates risk in a way that a larger one does not. One person knows how everything works. One device holds the files. One email account is the route through which clients, suppliers and authorities reach you, and it is often also the recovery method for every other account you hold.

None of this is a problem until something interrupts it, and then all of it is the same problem at once. The useful exercise is to work through what happens if the device fails, if the account is lost, or if you are unable to work for a month.

Backups that would actually survive the event

The failures that destroy records are rarely subtle: a drive stops working, a device is stolen, a folder is synchronised into oblivion, or a piece of software makes a mess and the mess is faithfully copied everywhere.

What protects against all of those is more than one copy, in more than one place, with at least one of them not connected to the others. A copy that updates automatically from the original is convenient and it will faithfully replicate a deletion, which is why it isn’t sufficient on its own.

And a backup nobody has tested is a belief rather than a backup. Restoring a single file occasionally, to confirm the process works and that the files are readable, is the difference between the two. Where records must be retained for a period, that requirement applies to the backup as much as to the original.

Access, and the accounts nobody else can reach

A small business accumulates accounts: the bank, the domain, the software, the platforms clients reach you through, the systems holding your records. Most of them are secured against everybody except you, which is the intention until the day somebody else needs to get in.

The arrangement worth making is that a trusted person could obtain access if you could not provide it. What form that takes depends on your circumstances and on the terms of the services involved, and it is worth a conversation with an accountant or adviser about the appropriate way to do it where you are — particularly for anything involving money or client information, where informal arrangements can create their own problems.

The simplest version is a written record of what exists and where, kept securely, so that whoever needs it knows what they are looking for. Access is a separate question and a harder one, but the inventory costs nothing.

What clients need if you disappear for a month

An unplanned absence is not only a loss of income; it is a set of commitments that continue in your absence. Work in progress, deadlines, and clients who are waiting and don’t know why.

A short note somewhere accessible — what each current client has been promised, when it is due, what state it is in — turns an impossible situation into a manageable one for whoever picks it up, and it is a document you can maintain in a few minutes a week.

The other half is having somebody who could deliver or hand over in an emergency. For many independent businesses that is an informal understanding with a peer in the same trade, reciprocated. It is worth arranging before it is needed, because the conversation is easy in advance and impossible in the middle of the event.

The obligations do not pause

Filing dates, payments and contractual commitments continue during an absence, and in most systems the fact that the person running the business was unwell does not automatically suspend them, though there may be provisions for particular circumstances.

This is worth raising with your accountant specifically: what would happen to your filings and payments if you were unable to deal with them for a period, and what arrangements can be made in advance. The answer varies by country and by structure, and knowing it is considerably better than finding out during the event.

Write down how things are done

The most valuable protection is the least dramatic one. A short set of notes describing how the business runs — how work is quoted, what the process is, where things are kept, which suppliers are used and what has been agreed with them.

It helps in an emergency, and it helps far more often than that. It is what makes it possible to hand work to somebody else, to take a holiday without carrying everything in your head, and eventually to sell the business rather than simply stopping. A business that exists only in one person’s memory is worth very little to anybody, including the person who built it.
