How to track customer credit and debts in a small shop

In many neighbourhood shops, credit is part of everyday business. A regular customer takes bread and milk on Monday and pays on Friday when wages come in. A supplier drops off stock and is paid at the end of the month. It builds loyalty, and it is often the only way customers can buy at all. But it is also where small shops lose the most money without noticing: a debt that wasn’t written down, a balance nobody remembers, or stock counted as sold when the cash never arrived.

This guide covers a simple system for recording credit, collecting it politely, and understanding what it does to your real profit, whether you use a notebook or an app.

Why credit sales need their own record

If you only record cash in the till, a credit sale disappears twice: the stock leaves the shelf, and no money arrives. Your stock count says you sold it; your cash says you didn’t. Over a month those gaps make it impossible to tell whether the business is actually making money or just moving stock.

Treat each credit sale as two facts: a sale, which happened today, and a debt, which stays open until it is paid. Supplier credit is the mirror image: stock you received today, and money you owe until you pay it.

What to record for every credit sale

• The customer’s name and a phone number, so there is never a question of which “Mama John” it was.
• The date.
• What they took, and the total. Item-level detail settles arguments later.
• Any amount paid now, and the balance remaining.
• When they promised to pay.

When a payment comes in, record it against that customer with the date and amount, and update the balance. Many shops let a customer pay part of a debt at a time, so the running balance matters more than any single entry.

Set limits before you need them

Decide in advance how much credit each customer can have, and for how long. A simple rule, such as no new credit while an old balance is more than two weeks overdue, is easier to apply than a decision made at the counter with the customer waiting. New customers can start with a small limit that rises as they pay reliably. Write the rule down, so staff apply it the same way you would.

Collecting without losing the customer

1. Review the list of open debts every week, oldest first.
2. Remind customers before a debt is late, not after. A friendly message the day before payday works better than a demand a month later.
3. Be specific: “Your balance is 1,250 for the items on the 3rd” is easier to act on than “you owe money”.
4. Offer a way to pay part now if the full amount is hard.
5. Pause credit, rather than ending the relationship, for customers who fall far behind, and say clearly what will restore it.

Don’t forget what you owe

Supplier credit needs the same care. Record each delivery you haven’t paid for, the amount and the due date. Paying suppliers on time protects your price and your access to stock; paying early when you don’t need to can leave you short of cash for the week. A list of what you owe, sorted by due date, makes that decision easy.

Know your real numbers

At the end of each month, look at three figures together: what you sold (cash and credit), the cash you actually collected, and the total customers still owe you. If the amount owed keeps growing month after month, the shop is lending more than it is earning, however busy it feels. Compare your profit with and without the uncollected debts, and you will see how much credit is really costing you.

Notebook or app?

A dedicated credit book works if you are disciplined about it: one page per customer, every sale and payment, and a weekly review. Its weaknesses are that it can’t add up totals for you, it can be lost or damaged, and it doesn’t connect to your stock.

An app removes the arithmetic. ShopFlow, our business management app for Android, was built for small shops that sell on credit: customer debts and supplier credits are records in their own right, alongside inventory, sales, purchases and analytics, so stock, revenue and profit are counted with credit in mind. Whichever you use, the habit matters more than the tool: record every credit sale at the moment it happens.
