Free GST invoice generator

Make a GST tax invoice online in about a minute. Enter your business, your customer and the items you sold. The tool works out CGST and SGST, or IGST, from the place of supply, adds an HSN-wise tax summary and the amount in words, and emails you the finished PDF. No sign-up, no card.

How to make a GST invoice

  1. Add your business. Business name, GSTIN and state. Your state is read from the first two digits of your GSTIN. Add your address and, if you like, your logo.
  2. Add your customer. For a registered business, enter their GSTIN. For a consumer, the name and state are enough.
  3. Set the invoice number and date. GST rules allow up to 16 characters: letters, numbers, / and -. Numbers must be unique within a financial year.
  4. Add items. Description, HSN or SAC code, quantity, unit, rate, discount and GST rate. Turn on Rates include GST if your prices already include tax.
  5. Check the preview, then get the PDF. The preview updates as you type. Enter your email and the final invoice, without the draft watermark, is sent to your inbox.

CGST and SGST, or IGST?

GST on a sale is decided by the place of supply:

  • Same state as your business: the tax is split equally into CGST and SGST. 18% GST becomes 9% CGST and 9% SGST.
  • Different state: the whole tax is IGST. 18% GST is charged as 18% IGST.

The tool picks this for you from your state and your customer's state. You can set the place of supply yourself when goods are delivered somewhere else.

What a GST tax invoice must show

Rule 46 of the CGST Rules lists what a tax invoice must carry. This tool covers each of them:

  • Your name, address and GSTIN
  • A unique invoice number (up to 16 characters) and the date of issue
  • Your customer's name and address, and their GSTIN if they are registered
  • The place of supply, with the state name and code
  • For each item: description, HSN or SAC code, quantity and unit, value, discount and taxable value
  • The GST rate and the CGST, SGST or IGST amount
  • Whether tax is payable on reverse charge
  • Your signature or that of an authorised signatory

HSN and SAC codes

HSN codes classify goods and SAC codes classify services. If your turnover was up to ₹5 crore in the last financial year, use at least 4 digits on business-to-business invoices. Above ₹5 crore, use 6 digits.

Frequently asked questions

Is the GST invoice generator really free? Yes. Every invoice is free and arrives by email as a PDF. You can make up to 10 invoices a day from one email address.

Why do I get the invoice by email instead of a download? The page shows a draft preview so you can check every number. The final PDF goes to your inbox, so you always have a copy you can forward to your customer.

Why is my invoice in a queue? Free invoices are generated in turn and usually arrive within a few minutes. In AxisIQ, invoices are created and sent instantly.

Can I add my logo? Yes. Add a PNG or JPEG logo and it prints at the top of the invoice.

Does this create an e-invoice (IRN)? No. Businesses with turnover above ₹5 crore must report B2B invoices to the Invoice Registration Portal to get an IRN. This tool creates a regular GST tax invoice.

What happens to the details I enter? We use your email to send the invoice and keep your contact details and a one-line summary of the invoice, so we can help with your billing. The full invoice is deleted from our queue once it is sent. Read our privacy policy.
