Keep the shop's money somewhere other than your own wallet

October 15, 2026 · Taro — Founder, KAZENA

You can usually say straight away how much is in the drawer or in your pocket. What you cannot say is how much of it belongs to the shop. You buy lunch out of today's takings, and you hand the delivery rider fuel money out of your own wallet. At the end of the day there is 1 mixed pile left, and that is all.

The mixing itself is not a mistake. A small business usually starts with your own money, so having only 1 wallet is the natural way to begin. The difficulty comes later, when the business keeps going and the questions you want answered start to pile up. Is this business making money. How much am I actually taking out of it. With 1 wallet, neither question has an answer.

What breaks a set of books is usually not a difficult transaction. V, an Indonesian accountant, has been testing KAZENA Books with her own real data more than 20 times, and what I learned from those exchanges is that the place where recording stalls most is where personal money and business money are mixed together. She does accounting work in Jakarta. The hard part is not the arithmetic, it is deciding after the fact which side a particular payment belonged to.

I tripped on the same spot. When I started the company I sometimes bought things for myself with the company card. I assumed that 1 or 2 of those would be easy to remember. In practice, 3 months later there were payments left where I could not tell whether the company owed me or I owed the company. The amounts were small, and because they were small I left them for later, and because I left them for later I could no longer remember.

The mixing runs in 2 directions. The shop's money buys something for your life, or your own money buys something for the shop. Leave the first direction alone and the shop's profit looks smaller than it is. Leave the second alone and the shop's costs look smaller than they are, so the business looks more profitable than you thought. Both make the numbers lie, and they lie in opposite directions.

Separating them means putting the money in a different place, and nothing more than that. In terms of what you can do today, decide on 1 place for the shop's money and put today's takings into it. If you cannot open a bank account today, an envelope or a box is fine. You can move it to an account later. What matters is that it is apart from your own wallet, and that there is only 1 place.

Once the places are apart, the next thing is how you decide your own share. Stop taking a little out whenever you need it, and instead hand yourself a set amount once a month. Whether that amount is right, you will not know at first. If it is too small, raise it next month. What matters is that the taking leaves 1 line behind. Then the shop's numbers stop moving every time your own life moves.

When you pay for something for the shop out of your own money, that is also 1 line. The date, the amount, what it was for, and the fact that you covered it yourself. This is money the shop owes you, so it has to sit somewhere, the same way an unpaid supplier bill does. Keep it in your head and it usually never comes back. You end up not knowing how much you have lent your own shop.

Once they are apart, the questions you can answer change. Is this shop earning enough to pay me a wage. Does today's price clear the purchasing, the rent and my own share added together. While everything is mixed, a little of your household spending is inside every figure, so the arithmetic never produces an answer. This is not a point about accounting knowledge, it is about seeing your own business with your own eyes.

KAZENA Books, which we build, is a tool for making the part after the separation easier. Upload the shop account's statement as a CSV and the AI reads it and proposes the category, the amount and the tax, and the person using it checks and approves. Invoices, receivables and payables are managed in one place too, so what you covered yourself can sit with the other unpaid items. But a tool will not make the separating decision for you. If household spending and purchasing arrive mixed in 1 account, the reading comes out mixed as well.

Keeping them apart also makes the last job lighter. The trial balance, the profit and loss, the balance sheet and the general ledger are built automatically and export to CSV or PDF whenever you want. What stalls you when you hand things to an accountant is not that output, it is deciding which payment belonged to which side. Only the person who paid, on the day they paid, knows that.

A short word on tax. I am not a tax accountant and not a lawyer, so please confirm any filing or payment decision with a professional. What I can say is that a payment you intend to explain as a business cost is easier to explain when it came out of the business's money. Explaining after the fact that a payment from 1 mixed account was half business is hard even for yourself.

Here is the one thing for today. Before you finish work today, decide on 1 place for the shop's money and move today's takings into it. Then, if you paid for anything for the shop out of your own wallet today, write that as 1 line. From tomorrow, 1 line every time money in that place moves. Keep it for 1 week and you will see, as your own figures for the first time, what your business is actually running on.
