Free GST Invoice Generator (India)

How to make a GST-compliant invoice in India

Every registered business in India must issue a tax invoice that carries specific fields. This free generator fills them for you — just enter your details on the left and the invoice on the right updates live.

1. Seller details — your legal business name and GSTIN.
2. Invoice number & date — a unique serial per financial year.
3. Buyer details — name (and GSTIN for B2B).
4. Line items — description, HSN/SAC, quantity, rate.
5. Tax split — CGST + SGST for intra-state sales, IGST for inter-state.
6. Total — taxable value + GST, with the amount in words.

CGST, SGST and IGST — what's the difference?

For a sale within your own state, GST is split 50/50 between Central GST (CGST) and State GST (SGST). For a sale to a customer in another state, a single Integrated GST (IGST) is charged at the full rate. The total tax is the same either way — only the split changes. This generator switches automatically when you change the supply type.
