  • Use a unique invoice number in sequence.
  • Write the place of supply and any payment terms in the notes.

Frequently asked questions

What must a GST tax invoice contain?

Broadly: the supplier's name, address and GSTIN, an invoice number and date, the customer's details, a description of goods or services with HSN or SAC codes, quantity, taxable value, the GST rate and amount, the total and the place of supply. Rules vary by case, so confirm requirements with your accountant.

When do I charge CGST and SGST, and when IGST?

If the supplier and the place of supply are in the same state, GST is split into CGST and SGST in equal halves. If they are in different states, IGST applies for the full rate.

What are HSN and SAC codes?

HSN codes classify goods and SAC codes classify services for GST. Use the code that matches what you sell. For website design and development services the commonly used SAC is 998314, but confirm with your accountant.

Is this invoice legally valid?

The tool lays out the standard fields and calculations, but you are responsible for the accuracy of rates, codes and details. It does not file returns or generate e-invoices or e-way bills.

Is my data saved or sent anywhere?

No. Everything runs in your browser and nothing is uploaded or stored. Closing the page clears it.
