Correct an invoice gracefully — returns, overbilling, post-sale discounts — with a properly numbered credit memo.
A credit note (credit memo) is the formal way to reduce what a customer owes after an invoice has been issued. The classic triggers: goods returned or rejected; an invoice that overstated quantity or price; a post-invoice discount or goodwill gesture; services that fell short of the agreed scope. Instead of deleting or editing the original invoice — which breaks your numbering and your audit trail — you issue a credit note that references it and offsets the amount.
The single most important field on a credit note is the reference to the invoice it adjusts. Use the PO / Reference field for “Against Invoice INV-042 dated …” so both documents tie together in your records and your customer's. If you created the invoice here, the → Credit note action in the workspace does this automatically — items carried over, ready to trim down to the credited amount.
Under Section 34 of the CGST Act, a registered supplier issues a credit note when a tax invoice overstates value or tax, goods are returned, or supplies prove deficient. The credit note must be reported in your GST returns (the deadline is tied to the 30th of November following the financial year, or the annual return, whichever is earlier), and the tax reduction is only available if the recipient reverses the corresponding input credit. The GST fields here — GSTIN, place of supply, HSN/SAC, automatic CGST/SGST/IGST split — apply to credit notes exactly as they do to invoices.
Credit notes get their own sequence (CRN-001…) per business profile, separate from invoices. Your invoice numbering stays unbroken — which is precisely the point of using credit notes instead of edits.
Like every tool on this site, the credit note maker runs entirely in your browser. Clients, line items and history are stored on your device in IndexedDB — never uploaded, never seen by us, exportable as a single backup file, deletable any time. It also works completely offline once loaded, and the PDF never carries a watermark.
Issue a credit note. Editing or deleting issued invoices breaks sequential numbering and audit trails; a credit note documents the correction while leaving history intact.
Yes — best practice (and a GST expectation) is to identify the original invoice number and date. Use the reference field, or convert directly from the invoice in your workspace.
Declare the credit note in your returns to reduce output tax liability; the recipient must reverse the matching input credit. The same GSTIN, HSN/SAC and CGST/SGST/IGST fields used on invoices are available here.
Yes — credit any subset of lines or a reduced quantity/price. The totals, tax split and amount-in-words recompute automatically.
