Tips for using this generator in India
- Turn on “Split into CGST + SGST” for customers in your own state. Turn it off and set the tax label to IGST for customers in another state.
- Add “Place of supply” as an extra field, so it prints in the invoice header.
- Use the code column for HSN or SAC codes.

GST invoice questions
When do I charge CGST and SGST instead of IGST?
Charge CGST and SGST, each at half the GST rate, when you and your customer are in the same state. Charge IGST at the full rate when the place of supply is in another state or for exports.
Is a GST invoice from a free generator valid?
Yes. GST law sets what a tax invoice must contain, not which software makes it. If the invoice has every required detail, a PDF from this generator is a valid tax invoice. Businesses above the e-invoicing turnover limit must also report B2B invoices on the Invoice Registration Portal.
Can I make a bill of supply here?
Yes. Composition dealers and sellers of exempt goods can change the invoice title to “Bill of Supply” and set the tax type to none.
