The fastest way to track who owes you in your shop is to record every credit sale the moment it happens, with the customer name and amount, and mark each repayment as it comes in, so you always know the exact balance instead of relying on memory. A paper notebook can do this, but it is slow, easy to lose, and impossible to total. A phone app does it in seconds and adds up the figures for you.
Why "selling on trust" quietly drains your shop
Across Cameroon, selling on credit is normal. A regular customer takes goods today and pays at month end. The problem is not the credit itself, it is the record. You remember the face but forget the amount. Three weeks later the money is simply gone, and you have already restocked with cash you should have recovered.
The shops that stay profitable are not the ones that refuse credit. They are the ones that never lose track of it.
A simple system that works
1. Log it immediately. When a customer takes goods on credit, record their name and the amount before they leave the counter.
2. Keep one balance per customer. Every new credit adds to their total; every payment reduces it. You should be able to answer "how much does Marie owe?" in one glance.
3. Record partial payments. Most repayments come in pieces. If you only track "paid" or "not paid," you lose the in-between, which is where most of the money sits.
4. Review weekly. Once a week, look at who owes you and for how long. The longer a debt sits, the harder it is to collect.
Doing it on paper vs in an app
A notebook has no search, no totals, and one spilled drink away from disaster. With Wé, every credit sale is tied to the customer automatically, partial payments are one tap, and the app shows you the full outstanding total at any time. You also get change IOUs, for the customer who pays with a 10,000 note when you have no change, so even that is not forgotten.
The bottom line
You do not need to stop giving credit to stop losing money. You need a record that adds up and never disappears. Track every balance, mark every repayment, and review who owes you each week.
