What a GST tax invoice must include
A compliant tax invoice (CGST Rule 46) needs the supplier and recipient names, addresses and GSTINs, a consecutive invoice number and date, the place of supply, and for each line the description, HSN/SAC code, quantity, rate, taxable value and GST. Intra-state supplies show CGST + SGST; inter-state supplies show IGST. The grand total is also shown in words.
This generator computes all of that with the same engine Quillix uses, including the per-line paise rounding and the tax-rate summary matrix, so the invoice you download matches production billing behaviour.
GST invoice generator — FAQ
Is this invoice generator really free?
Yes — free with a Quillix login, up to 15 invoice downloads a month. Everything else runs in your browser: the seller, buyer and item details you enter are not sent to any server.
How do I save the invoice as a PDF?
Click "Generate invoice", then "Print / Save as PDF". In the browser's print dialog choose "Save as PDF" as the destination.
Does it calculate CGST, SGST and IGST automatically?
Yes. It detects intra- vs inter-state from the seller and buyer states (or GSTINs) and applies CGST + SGST or IGST accordingly. You can override the supply type if needed.
Is the GSTIN checked?
The GSTIN is validated for correct format and checksum offline. This confirms it is well-formed; it does not check whether the GSTIN is registered on the GST portal.
