Set aside what is not yours on the day it arrives

The balance lies

A bank balance is a single number and it hides everything about where that money is going. A healthy-looking figure can be almost entirely spoken for: amounts collected on behalf of somebody else, obligations that fall due next quarter, deposits for work not yet delivered.

People who get into difficulty with this are not usually reckless. They are looking at a real number, drawing a reasonable conclusion, and being wrong because the number was never telling them what they thought it was.

Which money is not yours

The categories vary by country and by structure, and the specifics genuinely need a local accountant, but the shapes are consistent. There is tax on what the business earns, which is not due yet but is accruing with every invoice. In many systems there are consumption taxes collected from customers and passed on, which were never yours at any point. Where anybody works for you there are usually deductions and contributions to be handed over. And there are client deposits, which belong to the client until the work is done.

What unites them is that each is an obligation created by an event that has already happened. The money arriving today is what makes them payable. Spending it doesn’t remove them.

Move it the same day

The mechanism that works is embarrassingly simple: a second account, and a transfer made on the day money arrives rather than at the end of the month. What remains in the main account is then genuinely available, which restores the balance as a number you can act on.

Doing it on arrival rather than periodically matters more than it sounds. A monthly sweep requires a decision each time, and decisions made when the main balance looks thin tend to be postponed. A transfer made immediately, as part of the routine of recording the payment, never has to be decided at all.

Some people automate a percentage, some transfer a calculated amount per invoice. Either is fine. What fails, consistently, is intending to keep track of it mentally.

Setting the percentage

The proportion depends entirely on where you are, how you’re structured and what you earn, which is exactly why the figure should come from your accountant rather than from an article or a friend in another country.

Two general points hold regardless. Erring high is cheap, since surplus in the reserve is simply money you have, whereas a shortfall arrives on a fixed date and has to be found. And the proportion should be reviewed when income changes materially, because in most systems the relationship between income and what is owed is not a flat line.

A first year deserves particular care. In some systems the first payment covers a longer period than usual, or arrives alongside a payment on account for the following one, which produces a demand considerably larger than the year alone would suggest. Ask about that specifically, before the year ends.

What the reserve is not for

It is not a buffer, and treating it as one is how the discipline collapses. A business that dips into the obligation account during a quiet month is borrowing from a lender who doesn’t negotiate and doesn’t accept excuses, and repaying it requires a surplus that the quiet month was already evidence you do not have.

A trading buffer is a separate thing with its own separate account, funded from what is actually yours. Keeping them apart is the difference between a difficult quarter and a genuine crisis, and the separation costs nothing to maintain once it exists.

Why this is the highest-value habit in a small business

Very little else in running a business of one produces so much benefit for so little effort. It takes seconds per payment, requires no expertise, and removes the single most common cause of an otherwise viable business hitting a wall.

It also changes how the year feels. An obligation that has been fully provided for is an administrative event — a payment made from money already sitting there. The same obligation unprovided for is the thing that keeps people awake, and it is the same amount either way. The only difference is when the money was moved.

There is a secondary benefit that shows up in pricing. Once the obligations are being removed from every payment as it arrives, the figure left in the working account is close to what the business actually earns, and decisions get made against that instead of against a gross number. People who work this way tend to notice much sooner that a particular kind of job is not worth doing, because the money they see is the money that was ever really theirs.
