Free GST Bill Generator Online

How to make a GST bill online — 3 simple steps

1. Enter seller & buyer details. Add your business name and GSTIN, then the customer's details. The GSTIN is checked with the official checksum so a wrong number is caught before you print.
2. Add your items. As you type an item name, the tool suggests its HSN code and picks the correct GST rate automatically. CGST + SGST is applied for a sale inside your state, or IGST for a different state — worked out from the place of supply, and fully editable if you need to override it.
3. Download the PDF or print. One click gives you a clean A4 tax invoice with the amount in words and an optional UPI QR code, ready to send on WhatsApp or print on the spot.

What a valid GST invoice must contain

Under Rule 46 of the CGST Rules, a proper tax invoice needs the supplier's name, address and GSTIN, a consecutive invoice number, the date of issue, the buyer's details, the HSN code and description of goods or services, the taxable value, the GST rate and tax amount split into CGST/SGST or IGST, the place of supply, and the amount payable. This generator fills in every one of these mandatory fields for you, so the bill you hand a customer or upload for filing is compliant by default. For a copy-ready sample, see the GST invoice format guide, or learn the maths behind it in how to calculate GST.

GST or non-GST — which bill should you raise?

If your annual turnover is below the registration threshold (₹40 lakh for goods, ₹20 lakh for services in most states) you are usually not registered, and you should raise a plain non-GST bill or bill of supply without charging tax. Once registered, you must issue a GST tax invoice and collect CGST/SGST or IGST. The generator above handles both — leave GST on for a registered business, or switch it off with one tick for a simple bill. After the September 2025 reform the active slabs are 0%, 5% and 18%, with 40% on luxury and sin goods; the older 12% and 28% slabs were removed.
