Use the final invoice amount
Enter the name and UPI ID that should receive payment. Add the exact invoice total and a short note such as Invoice 1042 so the payer can recognise the request.
Download the invoice block
After creating the QR, choose Add to Invoice. The downloaded PNG includes the QR, recipient details, amount, note, and a reminder to check the recipient name before paying.
Confirm payment in your own app
The invoice QR requests payment but cannot tell whether money arrived. Check your UPI or bank app before marking an invoice as paid.
Need the whole invoice, not just the QR?
If you do not already have an invoice to drop this block into, the GST invoice generator builds the complete document as a PDF with the payment QR already placed near the total. It works out the CGST and SGST split, or IGST, from your GSTIN and the place of supply. Like this page, it runs entirely in your browser with no account and nothing stored.

Checking an invoice QR you received
Invoice QRs are a known target: a real invoice is intercepted and its QR swapped, or a convincing fake arrives from a spoofed address. Before paying a new supplier, read the QR with the UPI QR checker and confirm the UPI ID against one they gave you over a channel you started.
