Credit Note Generator
Issue GST credit notes against an invoice for returns, discounts and corrections
What is Credit Note Generator?
Credit Note Generator is a free business tool from Farvixo that lets you issue GST credit notes against an invoice for returns, discounts and corrections. Your business and client details stay in your browser and are never uploaded. The exported document carries no watermark and no branding of ours, so it can be sent to a client exactly as generated.
How to use Credit Note Generator
Put the invoice number you are correcting in the "Against invoice" field. A credit note that does not name its invoice is almost useless to the customer's accounts team and to an auditor.
Enter only the items and amounts being reversed, not the whole original invoice. Apply the same tax rate the original used — the tax reverses along with the value.
Credit notes get their own sequential numbering, separate from invoices. Check the preview and download.
Frequently Asked Questions
What is a credit note?
A document that reduces what a customer owes on an invoice already issued. Goods came back, the quantity was wrong, a discount was agreed after the fact, or the price on the invoice was too high. It is the correct instrument for all of those — editing or reissuing the original invoice is not.
Why can I not just cancel and reissue the invoice?
Once an invoice has been issued and reported, it is part of a numbered sequence and, where tax applies, part of a filed return. Deleting it breaks the sequence and the return. A credit note leaves the audit trail intact and shows what changed and when — which is exactly what a tax authority wants to see.
What is the difference between a credit note and a debit note?
A credit note reduces the amount the customer owes; a debit note increases it. If you undercharged, you issue a debit note (or a supplementary invoice). Same mechanism, opposite direction.
How does the tax reverse?
At the same rate the original invoice used. If the invoice charged 18% split as 9% CGST and 9% SGST, the credit note reverses in the same proportions. Applying a different rate leaves a mismatch that surfaces in reconciliation.
Is there a deadline for issuing one under GST?
For the tax adjustment to be claimable there is a time limit tied to the annual return and the following September — the exact cut-off has moved between amendments, so check the rule current for your period. After it, you can still issue a commercial credit note; you just cannot reduce your tax liability with it.
Should credit notes share the invoice number series?
No. Keep a separate sequential series with its own prefix. Mixing them makes both sequences hard to audit and confuses the customer's accounts payable.
Is anything uploaded?
No. The credit note is generated in your browser and nothing is transmitted or retained.

Tips for better results
- Use a consistent numbering sequence across documents — it matters for bookkeeping and for tax filing later.
- Check the tax fields against the rules where you operate; the calculation is only as right as the rate you enter.
- Keep a copy of every document you issue. Nothing is stored here, so the download is your only record.
Common problems and how to fix them
Totals do not add up as expected
Check whether the tax rate should apply per line or to the subtotal, and whether entered prices already include tax.
The logo looks blurry in the PDF
Upload a higher-resolution image. A small web logo scaled up for print will always soften.
Text overflows the layout
A field is longer than the template allows. Shorten the description or move the detail to a notes line.
