GST invoice generator (India)

An Indian GST tax invoice with GSTINs, HSN/SAC codes, CGST + SGST or IGST, amount in words and bank details.

Just need one? Fill it in and download it free

Create GST tax invoices in the familiar Indian format: supplier and recipient GSTINs and state codes, place of supply, HSN/SAC codes, taxable value, CGST and SGST for intra-state supplies (or IGST for inter-state), the grand total in figures and words, and your bank details.

Amounts use Indian digit grouping (₹1,20,000.00). Switch between intra-state and inter-state tax with one field, and render invoices in bulk from your billing system.

Frequently asked questions

Does it handle CGST, SGST and IGST?
Yes — set interState to false to show CGST and SGST columns, or true to show IGST instead. Rates and amounts come from your data.
Is this an e-invoice with an IRN?
No. Businesses above the e-invoicing threshold must register invoices on the Invoice Registration Portal to get an IRN and QR code. This template produces the invoice PDF; add the IRN and QR from the portal if you are required to.
Can I show the amount in words?
Yes — pass the amount in words (for example "Indian Rupees One Lakh Seventy-Seven Thousand Only") and it is printed under the items.
