When to use a credit note
- Goods came back after you billed.
- The invoice amount or tax was too high.
- You give a discount after the sale and need a traceable record.
Create one
- Go to Sales > Credit Notes and start a new credit note. The page is titled Credit Note.
- Pick the customer. Under Note Details you see the Note #, the Note Date, the Mode and the Reason. If the note is linked to an invoice, the original invoice is shown. Otherwise it says Not linked.
- Add the lines under Items. A line needs a quantity above zero. The screen refuses a note with no lines.
- Check the Summary: Subtotal, Discount, Taxable, CGST, SGST or IGST, Round Off and the total. A Cash discount can be a percent or an amount.
- Add Notes and Terms if needed, then save. You see Saved.
Do not delete or overwrite a finished invoice to hide a mistake. A linked credit note keeps a clean audit trail. Ask your accountant how to treat tax on it.
The same screen layout is used for Debit Notes (Purchases > Debit Notes), with Supplier instead of customer.
