About GST Invoice Generator — Free GST Bill Maker (India)
This free GST invoice generator creates a proper Indian tax invoice entirely in your browser — no sign-up, no watermark, and nothing is uploaded to any server. Enter your GSTIN and the tool validates it character by character, including the official check-digit, then auto-detects your state from the first two digits. Your business details are saved on your device, so the next invoice takes seconds.
The tax split is worked out for you. When the seller's state and the place of supply match, GST is split equally into CGST and SGST/UTGST; when they differ, the invoice switches to IGST automatically — exactly as the GST law requires for intra-state versus inter-state supplies. Each line item carries its own HSN/SAC code, quantity, rate and GST slab (0%, 5%, 12%, 18% or 28%), and the invoice adds a rate-wise tax summary, round-off and the grand total in words using Indian numbering — lakh and crore, not million.
When you are done, one click prints the invoice or saves it as a PDF using your browser's print dialog — only the invoice is printed, never the form. The layout follows the fields expected of a tax invoice under GST rules: consecutive invoice number and date, supplier and recipient GSTINs, place of supply with state code, reverse-charge declaration, taxable value, tax rate and amount, and a signature block. For B2C sales, simply leave the buyer GSTIN blank and pick the place of supply.
This tool is built for speed and accuracy for freelancers, shops and small businesses. It is not a filing tool: if your turnover crosses the e-invoicing threshold you must also register invoices on the government IRP portal, and complex cases (exports, SEZ, cess) deserve a word with your CA.

Frequently asked questions
Yes — completely free, with no sign-up, no watermark and no limit on the number of invoices. Everything runs in your browser: your GSTIN, customer details and amounts never leave your device. Your seller details and the current invoice auto-save locally so you can pick up where you left off.
By comparing state codes — the first two digits of a GSTIN. If the seller's state code matches the place of supply, it is an intra-state supply and GST splits equally into CGST and SGST/UTGST. If they differ, it is an inter-state supply and the whole tax is charged as IGST. The tool reads the seller's state from their GSTIN and defaults the place of supply to the buyer's GSTIN state, which you can override for bill-to/ship-to cases.
Two ways. First the format: 2-digit state code, 10-character PAN, entity code, the letter Z, and a check digit. Then the checksum: the 15th character is recomputed from the first 14 using the official mod-36 algorithm, which catches almost every typo. A green tick means the number is structurally genuine — but the tool works offline, so it cannot confirm the registration is active on the GST portal; use the government's "Search Taxpayer" for that.
Rule 46 of the CGST Rules requires, among other things: a consecutive invoice number and date, the supplier's name, address and GSTIN, the recipient's details (and GSTIN if registered), HSN/SAC codes, description, quantity and taxable value of each item, the tax rate and the CGST/SGST or IGST amounts shown separately, the place of supply with state name for inter-state sales, whether tax is payable on reverse charge, and the signature of the supplier. This generator includes all of these fields, plus the customary amount-in-words and round-off.
Yes. Leave the buyer GSTIN blank — the invoice will show the recipient as unregistered — and choose the place of supply from the state list so the CGST/SGST versus IGST split stays correct. This is exactly how B2C tax invoices work for registered sellers billing consumers.
Click "Download / Print PDF". Your browser's print dialog opens with only the invoice visible — choose "Save as PDF" as the destination (available in Chrome, Edge, Safari and Firefox on desktop and mobile) or send it straight to a printer. The A4 layout keeps the tax table, totals and signature block clean on one page for typical invoices.
