This is the most common accounting problem in small retail and it has nothing to do with accounting. It is a problem of one pocket. The till pays for stock and it pays for school fees, and both feel equally like "the shop's money", because in every practical sense they are.
The consequence is a specific and very familiar feeling: the shop appears to be doing well, the sales are there, the margins are reasonable, and yet there is never any money. People conclude the business is failing. Usually the business is fine and the measurement is broken.
Why a second bank account does not fix it
The standard advice is to open a separate account, and it is not bad advice. It is just not sufficient, because it does not touch the mechanism that causes the problem. The money that goes untracked is usually cash taken directly from the till on the way home — it never passes through either account. A shop with two bank accounts and an unlabelled till has exactly the same problem as a shop with one.
The account the money sits in matters much less than whether anybody wrote down which kind of money it was.
The habit, which takes two seconds
When money leaves the till, record it and label it. Business or personal. That is the whole method.
| Money leaving | Which | Why it matters |
|---|---|---|
| Paying a supplier | Business | A real cost of trading. Belongs in your profit calculation. |
| Shop rent, electricity, staff wages | Business | Same. These are what the shop costs to run. |
| School fees, groceries, a family medical bill | Personal | Real money leaving, but not a cost of the business. Counting it as one makes the shop look unprofitable when it is not. |
| Your own wages, however you take them | Personal | This is drawings, not an expense. Tracking it is how you find out what you are actually paying yourself. |
| A phone bill you use for both | Split it, roughly | An approximate split recorded is worth far more than an exact one you never do. |
What a month of this shows you
People are usually surprised by two things. The first is how much the personal column adds up to — not because it is extravagant, but because nobody has ever seen it as a single figure before. The second is that the business column is smaller than they expected, which means the shop's real costs were lower and its real margins better than they had assumed.
Both of those facts change decisions. If you know the shop generates a certain amount and you take out a certain amount, you can answer the question that was previously unanswerable: is there room to hire someone, take on more stock, or put money aside — or is the shop already fully committed?
