What must a GST tax invoice contain?
Rule 46 of the CGST Rules lists the details a tax invoice must show. This generator has a field for each one:
- Your name, address and GSTIN
- A unique invoice number (up to 16 characters: letters, numbers, “-” and “/”, in one series per financial year) and the date
- The customer’s name and address, and their GSTIN if they’re registered
- Place of supply (state name and code) for inter-state supplies
- HSN code for goods or SAC code for services
- Description, quantity with unit, and value of each item, plus any discount
- Taxable value, the GST rate, and the CGST, SGST/UTGST or IGST amount
- Whether tax is payable on reverse charge
- Signature of the supplier or an authorised person
When you download, print or email, a quick check points out anything missing, such as your GSTIN, a state or an HSN code. Tap an item to jump to that field, or continue anyway.
CGST + SGST or IGST?
When you and your customer are in the same state, GST is split in half: 18% becomes 9% CGST + 9% SGST. When the goods go to another state, the whole 18% is charged as IGST. The generator reads both states and picks the right one automatically. You can check any amount with the GST calculator, and a customer’s GST number with the GSTIN validator.
Get paid faster with a UPI QR code
Add your UPI ID once under Payment details. Every invoice then carries a QR code with the exact amount filled in, so your customer scans and pays without typing anything. Your bank details print alongside for NEFT/RTGS payments.
Invoice numbering tips
- Use one series per financial year, e.g.
INV/26-27/001, and never reuse a number. - Separate series for different branches or document types are allowed. Keep each one consecutive.
- After you download, Next invoice moves to the next number automatically: INV-009 becomes INV-010.
