DeynbookA record of what customers owe
A deyn book is a customer debt record. When a business gives a customer goods or services on credit, it records the amount owed. Later payments reduce that balance. The record can be a notebook or a digital ledger.
For a pharmacy, shop, small restaurant or another business that sells on credit, the question is the same: who owes money, how much have they paid, and what remains?
Example: $50 owed, $20 paid, $30 remaining
This is an illustrative example, not a real customer account. A customer takes goods worth $50 on credit, then pays $20 a few days later.
| Record | Debt added | Payment | Remaining |
|---|---|---|---|
| Credit sale | $50 | — | $50 |
| Partial payment | — | $20 | $30 |
Remaining balance = recorded debts − recorded payments. Keep both entries rather than replacing the original $50 with $30. That preserves the history of how the balance changed.
What to write down
- Customer: a name that identifies the person clearly; add contact details where useful.
- Debt: the amount, date and a brief explanation of the credit sale.
- Payment: the amount and date, including partial payments.
- Balance: the remaining amount after each entry.
Review entries with the customer when resolving a disagreement. A ledger records the transactions you enter; its accuracy still depends on recording them correctly.
Paper or digital?
A notebook can work, but finding past entries and checking totals becomes harder as records grow. A digital debt book keeps each customer’s transactions together and calculates the balance from those entries.
Before moving existing balances into a new system, check them against your current records. Do not enter the same opening debt twice or assume an old balance is correct without reviewing it. Follow the paper-to-digital checklist.
