GST Invoice Generator
Create professional GST invoices, bills of supply, proforma invoices and quotations in minutes — tax is calculated for you, the PDF is ready to send, and your data never leaves this device.
At a glance
- Makes tax invoices, bills of supply, proforma invoices and quotations as a ready-to-send A4 PDF with real, searchable text.
- Charges CGST + SGST when the place of supply is in your state and IGST when it isn’t — per item, rounded to the paisa, with an HSN/SAC-wise tax summary.
- Checks GSTINs (format, state code and check digit) and fills in the state and PAN from them.
- Adds a UPI QR code for the exact amount, your bank details, logo, signature, the amount in words and an optional original, duplicate and triplicate set.
- Handles discounts, GST-inclusive prices, round-off and numbering (INV-007 → INV-008). Long item lists continue onto more pages.
- Works offline once loaded: your business details, customers and the last invoice are saved only in this browser, with a backup file you can keep.
