GST invoice generator, in Tamil or English
Fill it in, print it or save it as a PDF. It works out CGST and SGST for a sale inside Tamil Nadu and switches to IGST the moment the buyer is in another state. Free, no sign-up, and nothing you type leaves your phone.

The one thing most hand-made invoices get wrong
Inside Tamil Nadu: CGST + SGST
Selling from Coimbatore to Madurai is an intra-state supply, so an 18% item is billed as 9% CGST and 9% SGST. Two lines, not one.
Outside Tamil Nadu: IGST
Coimbatore to Bengaluru is inter-state, so the same item is billed as a single 18% IGST line. Charging CGST and SGST here is the error we see most often, and it is a nuisance to correct later.
Questions
When do I charge CGST and SGST, and when do I charge IGST?
If your state and your buyer's state are the same, the GST rate splits into CGST and SGST, half each — an 18% item becomes 9% CGST plus 9% SGST. If the buyer is in another state, the whole 18% is charged as IGST instead. This tool switches automatically when the two state fields differ, so getting it wrong is hard.
Is this really free, and where does my data go?
It is free and nothing is sent anywhere. The invoice is built inside your browser tab, so your customer's GSTIN and your prices never touch our server. Closing the tab clears everything, which also means you should print or save the PDF before you leave.
Can I make the invoice in Tamil?
Yes. The language toggle at the top switches every label on the invoice to Tamil, including the totals and the signature line. The numbers stay in figures, which is what the trade expects.
Does it write the amount in words?
Yes, in the Indian system — lakh and crore rather than million. It updates as you type and is included when you print.
Is a printed invoice from this legally valid?
The format follows the fields a GST tax invoice is expected to carry, but we are a software studio, not your accountant. If something about your situation is unusual — reverse charge, exports, e-invoicing thresholds — check with your CA before relying on it.
