How to create a GST invoice
A complete invoice in about two minutes.
You'll need: Your GSTIN (if registered) · Customer details · HSN/SAC codes

Add the customer
Enter the buyer’s name and address, and their GSTIN for B2B invoices. The place of supply is picked from their GSTIN automatically; check it for unregistered buyers.
Add items
For each item or service add a description, HSN/SAC code, quantity, rate and GST %. Taxes and totals update instantly.
Download the PDF
Add bank details, a UPI ID for a payment QR, and notes, then download the PDF and share it with your customer.
CGST, SGST or IGST — which applies?
| Sale | Taxes | Example at 18% |
|---|---|---|
| Seller and place of supply in the same state | CGST + SGST (or UTGST in some union territories), split equally | 9% CGST + 9% SGST |
| Seller and place of supply in different states | IGST | 18% IGST |
The tool decides automatically by comparing your state with the place of supply.
GST rates after September 2025
From 22 September 2025, GST was simplified: most goods and services moved to the 5% or 18% slabs, the 12% and 28% slabs were removed, and a 40% rate applies to a small set of luxury and sin goods. Special rates such as 3% (gold) and 0.25% (rough diamonds) continue, and many essentials are 0%. The old 12% and 28% options remain in the tool for invoices dated before the change. Always confirm the rate for your HSN code with your accountant.
What a GST tax invoice must include
Under Rule 46 of the CGST Rules, a tax invoice includes, among other details:
- Supplier name, address and GSTIN
- A unique invoice number (up to 16 characters, unique for the financial year) and date
- Recipient name, address and GSTIN if registered (and state details for unregistered buyers above the threshold)
- HSN or SAC code, description, quantity and unit
- Taxable value, GST rates and amounts split into CGST/SGST/UTGST or IGST
- Place of supply
- Signature of the supplier or authorised representative
Check the current rule text and any e-invoicing obligations that apply to your turnover with your chartered accountant.
Do you need e-invoicing?
Businesses above the notified turnover limit must generate e-invoices (with an IRN and QR code from the government’s invoice registration portal) for B2B supplies. This free tool creates standard tax invoices; if e-invoicing applies to you, you’ll need billing software connected to the IRP. We build custom GST billing software with e-invoicing, e-way bills, stock and Tally export.
Frequently asked questions
Is this GST invoice generator free?
Yes. It is free, needs no sign-up, and creates a PDF invoice in your browser.
Is my invoice data uploaded anywhere?
No. Everything runs in your browser. If you tick “remember”, your business details are saved only in this browser on this device.
Can I create an invoice without GSTIN?
Yes. Leave the GSTIN empty — unregistered businesses can use it for simple bills, though a GST tax invoice requires registration.
How does the tool choose CGST/SGST or IGST?
If your state and the place of supply are the same, it applies CGST and SGST (UTGST in certain union territories); otherwise IGST.
Can I add my UPI QR code to the invoice?
Yes. Enter your UPI ID and the PDF includes a QR code with the invoice amount filled in.
Does it support e-invoicing (IRN)?
No. E-invoices must be registered on the government portal; that needs billing software integrated with the IRP.
