Free Credit Note Generator
A credit note is used when an invoice needs to be reduced or cancelled — because of a return, a discount agreed after the fact, or a billing error. It preserves the audit trail rather than deleting the original invoice.

What the Credit Note Generator does
A credit note is a formal document that reduces or cancels an amount already invoiced, issued for returns, discounts agreed after billing, or invoicing errors, while keeping the original invoice intact for audit purposes.
Methodology and formula
Credited amount ≤ Original invoice total; for GST supplies, Credit note GST = Credited taxable value x Original GST rate, referencing the original invoice number and filed in the corresponding GSTR-1 period.
Worked example
- Inputs
- Original invoice INV-0102 for ₹1,18,000 (incl. 18% GST); 10% goodwill discount agreed after delivery.
- Result
- Credit note for ₹11,800, referencing INV-0102, reducing net payable to ₹1,06,200.
Because GST credit notes must be reported in the same or a later GSTR-1 filing period, issuing it promptly avoids a mismatch between the supplier's and buyer's input tax credit claims.
When to use this tool
Use this whenever you need to reduce an amount already billed on a real invoice — never edit the original. If GST was charged on the original invoice, use the GST Invoice Generator's figures as the reference point for the credit note.
About the Credit Note Generator
When to issue a credit note
Issue one whenever you agree to reduce an amount the client owes you: returned goods, a service level miss, a duplicate invoice, or a negotiated discount after invoicing. Never edit or delete the original invoice — issue a credit note against it.
Full vs partial credit
For a full cancellation, the credit note amount matches the original invoice total. For a partial adjustment, enter only the credited amount and describe the reason clearly ('10% goodwill discount on INV-102').
Impact on GST and accounting
Under GST, credit notes must reference the original tax invoice and be reported in the same or a subsequent GSTR-1 filing. Elsewhere, treat the credit note as a negative sale in your books.
