How do most small shops keep record of credit sales?

An exercise book behind the counter, one line per credit sale. It works well for a shop with a handful of debts and stops working when nobody adds up the total, because the book then tells you individual debts but never how much your shop is owed altogether.

Is a notebook or an app better for credit sales?

A notebook is better than an app you do not open. What decides it is whether the method adds up the total for you, and whether one person can both create a debt and clear it.

Should each customer have their own page?

Yes, if you use paper. A book kept in date order tells you what happened on Tuesday; a book kept by customer tells you what Mama Nkechi owes, which is the question you actually need answered when she walks in.

Can I keep credit records on my phone?

Notes and WhatsApp messages to yourself work for a day or two and fail over a month, because there is no total, no order, and nothing stopping two entries for the same debt. If you use a phone, use something that adds up.

How do I know my credit record is working?

Try to answer three questions in under a minute: who owes me, how much altogether, and since when. If any answer needs you to read back through pages, the method is not working yet.

How Shops Actually Keep Record of Selling on Credit

The exercise book, the phone, the ledger, the app. What real shops use to track who owes them, where each one breaks, and the test any method has to pass.

Walk through any market and you will find the same debts kept four different ways. One trader has an exercise book. The next writes on the back of a receipt roll. Another sends herself WhatsApp messages. A fourth keeps a proper ledger with a page per customer and can tell you, without looking, that Baba Tunde has owed ₦12,000 since the second week of the month.

All four are keeping record of selling on credit. Only one of them can say how much the shop is owed right now, and by whom. The other three can tell you that somebody took rice on Tuesday.

The exercise book

This is what most shops use, and for a shop with five or six debts it is enough. One line per credit sale, written as the goods leave.

Where it breaks is the total. A book in date order holds every debt but never adds them, so the owner knows about the debts one at a time and never sees the pile. Two thousand here and five thousand there feels small on separate pages. Written on one line at the bottom of the week it can be a third of your stock.

The other weakness is repair. When a customer pays half, most people cross the line out and write a new one somewhere else. Two weeks of that and the book has three versions of the same debt with no way to tell which is current.

The page-per-customer ledger

Same book, different order, and much better. Every regular credit customer gets their own page. Their debts go down the left, their payments down the right, and the difference is what they owe.

This is the method that survives an argument. When someone insists they paid, you turn to their page and read the dates back. It also answers the walk-in question straight away, because you look up a person rather than reading through a month of days.

A page per customer answers the question you are actually asked.

The cost is that you now keep two things in step: the page and the shop total. Set aside one evening a week to add every page's closing figure into a single number. Without that number you are back to knowing your debts one at a time.

Notes and WhatsApp on the phone

Very common, and worse than it looks. Writing "Kemi 3 bags 15k" into your notes at the counter takes five seconds and feels safer than paper, because the phone is always with you.

It fails over a month for three reasons. Nothing adds up, so there is still no total. Nothing enforces one entry per debt, so the same 15,000 appears twice when you record it once at the counter and again when you get home. And nothing separates paid from unpaid, so old notes and live debts sit in the same list until you cannot tell them apart.

If the phone is where you are comfortable, that is fine. Use something on it that keeps a running total.

A spreadsheet

A spreadsheet does the adding up, which is the main thing paper does not. One row per credit sale, columns for customer, phone, item, amount, date and date paid, and a total at the bottom that updates itself.

It works well for whoever built it and badly for everyone else. Staff will not open it mid-sale, so entries get made at closing time from memory, which is exactly when detail goes missing. Treat a spreadsheet as the owner's weekly review rather than the place a credit sale gets recorded.

What every method has to capture

Whatever you use, one credit sale needs the same handful of facts: the customer's name, a phone number, the item and quantity, the amount, the date, and the date they promised to pay. There is a fuller version of this in how to record credit sales, including how much credit to allow before you say no.

The phone number is the one people leave out, and it decides whether a debt is collectable at all. A name with no number is a story about someone who took your goods.

Two places means two wrong totals

Three of those four traders keep the same debts in two places, and that is why their numbers disagree.

A debt written in the book on Monday and on the phone on Thursday is two debts as far as your memory is concerned, and neither total is right. Pick the method you will actually keep, then close the others. If you move from a book to an app, carry the open debts across, then draw a line under the last page of the book and stop writing in it.

Who is allowed to clear a debt

Any method used by more than one person needs this rule: staff may record a credit sale, only the owner marks it paid.

Without it credit becomes the easiest way to hide a pocketed sale. A staff member sells for cash, writes it down as credit to a name, and clears the debt himself a week later. Stock is gone, the book balances, and nothing looks wrong. Splitting those two actions between two people costs nothing and closes the gap.

The one-minute test

Your method is working when you can answer these three, without reading back through anything:

Who owes you money today?
How much altogether?
Which of those debts is past the date it was promised?

Try it now with whatever you use. Most people can answer the first, guess at the second, and cannot answer the third at all. The third is the one that decides whether you get paid, which is the subject of collecting money a customer owes you.

One list, a total, and a way to reach each person.

Doing it with an app

MyShopGuard keeps credit as part of the sale rather than in a separate book. You mark a sale as owing and put a name and number on it, and it joins one list grouped by customer, with the total owed on your home screen beside the cash you actually took today. Each customer has a tap-to-call button and each debt shows its date, so the first two questions above are answered for you and the third is a glance down the dates. Staff can record a credit sale and cannot mark one paid, so a pocketed sale cannot be cleared by the person who took it.

Start here

Take whatever you use now and add up every open debt into one number. Write that number and today's date at the front of the book, or anywhere you will see it. Next week, do it again. If the number is climbing while your stock is falling, your shop is lending, and what that does to your profit is worth reading next.
