Frequently Asked Questions
Is this GST invoice generator completely free?
Yes — no sign-up, no subscription, no hidden fees, no invoice limit.
Does the invoice meet GST legal requirements?
Yes. It includes all mandatory fields under Section 31 of the CGST Act — GSTIN, invoice number, date, HSN/SAC codes, taxable value, CGST/SGST/IGST amounts, and place of supply.
How does the tool decide between CGST+SGST and IGST?
It compares the supplier's state code with the buyer's place of supply state code. Same state = CGST + SGST split equally. Different states = full IGST. This follows Section 7 and Section 8 of the IGST Act, 2017.
Can I apply different GST rates per item?
Yes. Each line item has its own GST rate selector (0%, 5%, 12%, 18%, 28%). The PDF includes an HSN-wise tax summary table showing the consolidated breakup — exactly as Tally shows it.
How do I export to Tally?
Click 'Tally XML' button to download an XML file importable into TallyPrime or Tally ERP 9 as a Sales voucher. Ledger names follow Tally's standard GST ledger naming conventions.
Is the GSTR-1 JSON compatible with the GST portal?
The JSON follows the GSTN GSTR-1 offline tool format with b2b, b2cs, and HSN summary sections. You can import it into the GST Offline Tool or reference it for manual filing.
Is my data safe?
100% private. All processing happens in your browser. Nothing is uploaded to any server. Drafts are saved only in your browser's local storage.
What invoice types are supported?
Tax Invoice, Proforma Invoice, Credit Note, and Debit Note — all with appropriate GST treatment.
