Nobody in a shop searches for “what is a customer ledger.” They search how much does this customer owe? Then: how do I write down a credit sale, a payment, a return, without losing the notebook.
Kaymn Accounting at kaymn.net is that book in the browser. It is not the community on kaymn.com, not a tax invoice, and not a till.
The number is the sum, not a memory
If you erase “200” and write “250”, you cannot explain the extra 50 when they ask. A credit sale increases what they owe. A payment, or a return you accepted, brings it down. Tracking means a new entry each time. The balance is whatever the book adds up to.
Who goes in the book? Anyone you sell to on credit more than once. A supplier you owe money to belongs there too. People who always pay cash can wait until they start buying on credit.
A credit sale, then a payment
- Add their name once.
- Credit sale: date, amount, currency, a short note, marked as money they owe you (Receivable in Kaymn).
- Payment: a new entry so the balance falls. If it goes up, you marked it the wrong way.
- A return is its own entry. Don’t delete the sale.
Fifteen minutes at the end of the day beats a week of “I’ll write it later.” If you are leaving paper: put today’s balance in, then only new entries. Don’t retype years of notebooks.
Collecting: their statement, not the whole shop
Asking for money without a statement turns into an argument. Send their account only. Kaymn can share a link. It does not send automatic WhatsApp reminders. See when Excel is enough.
