GST worked out for you
CGST and SGST inside your state, IGST outside it. Prices with or without GST, and round-off when you want it.
Send bills on WhatsApp
One tap sends the bill to your customer on WhatsApp or email, with a link they can open on any phone.
UPI QR on every bill
Your UPI QR is printed with the bill amount already filled in, so customers pay the right amount.

Keep billing when the network drops. Bills are saved on the device and sync on their own when you are back online.
Your logo, your design
Pick an invoice template and your brand colour. Your logo goes on the bill, nobody else's.
