A free GST invoice maker for small businesses and freelancers
Most invoice apps ask you to sign up, add their logo, or limit you to a few invoices a month. This one runs in your browser, remembers your business details on your device, and creates a clean A4 PDF with every field a GST tax invoice needs, plus a UPI QR code with the exact amount so customers can pay in seconds.
Check rates with the GST calculator, send a quotation first, or create a standalone UPI QR poster for your counter.
How to use the GST Invoice Generator tool
- Fill in your business details (saved for next time).
- Add the customer and choose both states (sets CGST/SGST or IGST).
- Add items with HSN/SAC, quantity, rate and GST %.
- Optionally add your UPI ID for a pay-now QR, then download the PDF.

Frequently asked questions
What must a GST invoice contain?
Supplier name, address and GSTIN; a unique invoice number and date; buyer name and address (and GSTIN if registered); HSN/SAC codes; quantity, rate and taxable value; the GST rate and amount split into CGST + SGST (same state) or IGST (different state); place of supply; total in figures and words; and a signature.
When is IGST charged instead of CGST + SGST?
When the supplier's state and the place of supply (usually the buyer's state) are different. The generator switches automatically when you choose the states.
Can I add a UPI QR code to the invoice?
Yes. Enter your UPI ID and the invoice gets a "Scan to pay" QR with the exact amount, so customers can pay instantly with any UPI app.
Is my business data saved?
Your business details and the last invoice number are saved only in this browser, so the next invoice is quicker. Nothing is uploaded.
Is this valid for e-invoicing?
Businesses above the e-invoicing turnover threshold must generate an IRN on the government IRP portal. This tool creates regular tax invoices for smaller businesses and freelancers. For price quotes, use the quotation generator.
