Use Incomes for receipts that are not already recorded as invoice payments or customer advances.
1. Identify the receipt
Check whether the money paid an invoice, was received before an invoice, or came from another supported source. Invoice receipts belong in Manage Payments; advances belong in Payments Received.
2. Start other income
For standalone income, open Invoicing → Incomes and choose New Income.
3. Enter its details
Review title, actual date, amount, currency, category, and receiving account. Add the customer or source where relevant.
4. Save and verify
Save the income and find it in the list. Compare with existing receipts so the same money is not counted both as an invoice payment and standalone income.
