GST Invoice Kit

Fill in the buyer and items, click Print, save a clean A4 PDF. The kit works out the tax split and checks the fields a GST invoice needs. Open the demo full screen (prints with a DEMO mark).

• Four documents: tax invoice, bill of supply (with the composition dealer line), credit note, debit note.
• Tax split by state: CGST + SGST inside your state, IGST outside, UTGST in Union Territories. SEZ / export and reverse charge options.
• Discount, cess and round off per invoice. Amount in words in lakh and crore.
• GSTIN check: state code and check digit, so typos show before you print.
• Invoice numbers: auto series per document type and financial year (INV/2026-27/001), max 16 characters.
• Your details saved: business, logo, bank and UPI ID fill in every time. Works offline; nothing leaves your computer.
• For developers: GstInvoice React + Tailwind component and gst.ts with the same tax rules, typed.

Good to know: e-invoice (IRN and QR) and e-way bills are made on the government portals, not here. Saved details stay in one browser on one computer. The kit lays out your invoice; confirm rates and HSN codes with your CA.
