What is a GST-compliant invoice?
Under Indian GST law, a tax invoice for a registered business is expected to carry certain mandatory fields. This tool covers most of them — the rest (an authorized signature, and actual GST registration) is on you.
- Invoice number and date
- Seller's name, address, and GSTIN
- Buyer's name and address (and GSTIN, if registered)
- HSN/SAC code for each item or service
- Description, quantity, and rate for each line item
- Taxable value and GST rate applied
- CGST + SGST (same state) or IGST (inter-state) amount, shown separately
- Total invoice value, and the place of supply
- Signature of the supplier or an authorized representative (not covered by this tool)
FAQ
Do I need a GSTIN to generate an invoice?
Only if you're GST-registered and legally required to charge GST. Businesses below the registration threshold can still issue a regular bill of supply without a GSTIN — just leave that field blank.
What's the difference between CGST/SGST and IGST?
When the seller and buyer are in the same state, GST splits evenly into CGST (goes to the central government) and SGST (goes to the state government). When they're in different states, the full rate is charged as IGST instead. This tool switches automatically based on the seller/buyer state you pick.
Is this invoice legally valid for GST filing?
This tool produces a correctly formatted invoice, but it isn't filing or compliance software — it doesn't validate your GSTIN, submit anything to the GST portal, or replace an accountant. Treat it as a formatting and calculation aid, not a filing system.
Is my customer's data stored anywhere?
No — only your own seller details are optionally saved, and only in your browser's local storage via "Save as template". Buyer details and line items are never stored and never leave your browser.
