About OpenBill Pro & OpenSoz
The debut flagship initiative by OpenSoz — crafting high-performance, affordable billing tools for 6.3 Crore Indian shop owners and entrepreneurs.
The Story of OpenSoz & OpenBill Pro
OpenSoz was founded with a singular, clear conviction: modern Indian shopkeepers, retailers, and small businesses deserve world-class software without the heavy baggage of overpriced annual AMC contracts, complex hardware dongles, and predatory payment gateway cuts.
As an independent Indian developer brand, OpenSoz builds community-first, accessible, and high-efficiency digital tools designed specifically for the unique rhythm of Indian retail — from bustling textile hubs in Surat and electronics markets in Bengaluru to neighborhood kiranas and medical stores across Tier 2 and Tier 3 cities.
OpenBill Pro is the debut flagship project of OpenSoz. It combines lightning-fast GST billing, zero-commission dynamic NPCI UPI QR payments, and automated WhatsApp delivery into an intuitive application that runs smoothly on any smartphone or desktop.
