What is a GST invoice?
A GST invoice is a bill a registered business issues for goods or services, showing the GST charged. In India it typically includes the seller's and buyer's details and GSTIN, an invoice number and date, a description of the goods or services, the taxable value, the GST rate, and the tax split as CGST + SGST (for sales within the same state) or IGST (for inter-state sales). This generator formats all of that for you and totals it automatically.

Frequently asked questions
Is this GST invoice generator really free?
Yes. You can create and download unlimited GST invoices as PDFs for free, with no sign-up required. The invoice is built right in your browser.
Do I need a GST number to make an invoice?
No. If you are not GST-registered you can leave the GSTIN fields blank and set the tax type to 'No GST', or simply omit the tax. If you are registered, add your GSTIN and choose CGST+SGST (same state) or IGST (different state).
What is the difference between CGST/SGST and IGST?
For a sale within the same state, GST splits into CGST and SGST (half each). For a sale to a different state, the full rate is charged as IGST. This tool applies the split automatically based on the tax type you pick.
