PepulBill turns any smartphone into a shop's billing counter — no POS machine, no printer, no paper. Customers scan a QR, order in Tamil or English on their phone, and the bill lands on their phone. Cash, card, or LankaQR, with a built-in change calculator. Built in Jaffna for small shops that can't justify a lakh-rupee POS. Bills are paperless — thermal receipts can't be recycled, so it's green from the first scan. Zero hardware. Zero paper. Smarter Billing, Greener Tomorrow.
