How does the tool decide between IGST and CGST?

The tool reads the first two digits of the GSTIN (state code). If the seller state matches the place of supply, CGST + SGST is applied. Otherwise, IGST is used.

Can I create invoices with multiple GST rates?

Yes. Enable the 'Different GST % for each item' option to apply different GST slabs like 5%, 12%, or 18% within the same invoice.

Is amount in words mandatory on GST invoices?

Yes. Indian GST invoices require the total amount to be mentioned in words. This tool automatically converts the final amount into words.

What happens if I enter an invalid GSTIN?

The GSTIN is validated in real-time. If it is invalid, the field is highlighted and invoice generation is blocked.
