Send a WhatsApp message describing the sale — items, quantities, customer name. Zeno understands messy, real-world language.

"Ramesh ko 3 cotton shirts bheja, 500 ka ek"

Zeno creates the invoice

GST calculated automatically. PDF generated instantly. Invoice sent to your customer on WhatsApp with one tap.

Payment link included

Every invoice includes a UPI payment link. Customer pays. You get notified instantly. Udhaar balance updates automatically.

"₹1,500 received from Ramesh. Settlement in 2-3 days."

UPI Payment Links

Mark any invoice as udhaar (credit). Zeno tracks the balance per customer and sends automated reminders so you never forget to collect.
