What this invoice includes
Rule 46 of the CGST Rules lists what a tax invoice must contain. The generator lays them out for you: the words "Tax Invoice", your name, address and GSTIN, a unique invoice number, the date, the buyer’s details and GSTIN where they are registered, the place of supply, and for every item its description, HSN code, quantity, taxable value, GST rate and the tax split. It closes with the total in figures and words and an authorised-signatory line.
The full list of mandatory GST invoice fields →CGST and SGST, or IGST — chosen for you
Pick your state and the buyer’s state. When they match, the invoice splits the tax into CGST and SGST; when they differ, it charges IGST at the full rate. Each item is taxed at its own rate, so one invoice can carry 5% and 18% goods together.
Saving the invoice as PDF
Click Download PDF / Print and choose "Save as PDF" in the print window. Only the invoice is printed — the form around it is hidden — on an A4 page. Your business details are remembered on this device, so the next invoice starts with them filled in.
Numbering your invoices
An invoice number can be up to 16 characters of letters, numbers, hyphens and slashes, and must be unique within the financial year. Most sellers use a short prefix and the year, such as INV/26-27/0001, and never reuse a number. The tool warns you if a number breaks those rules.

Under Rule 46 of the CGST Rules: the words "Tax Invoice", supplier name, address and GSTIN, a unique serial number of up to 16 characters, the date, recipient details and GSTIN if registered, place of supply, HSN code, description, quantity, taxable value, GST rate and amount (CGST and SGST, or IGST), and a signature.
How do I download the invoice as PDF?

Does the tool store my invoices?
No invoice is sent to our servers. Your own business details are saved in your browser on this device so you do not have to retype them; clearing your browser data removes them.
When should I charge IGST instead of CGST and SGST?
Charge IGST when your state and the place of supply (the buyer’s state) are different. Charge CGST and SGST, split equally, when they are the same.
