4000+ Merchants Empowered | LKR 10+ Billion Processed | First ISO 27001 Certified Gateway
In an era where fintech platforms race for attention with flashy rebrands and slogans, OnePay has quietly and powerfully built the infrastructure powering a digital economy. Today, the company celebrates a major milestone: 4 years of operation, over LKR 10 billion in payment volume, 4,000+ active merchants, and a clear reputation as Sri Lanka’s most advanced and trusted payment platform.
Founded in 2021 by Spemai (Pvt) Ltd and backed by a reputed Japanese corporate investor since 2019, OnePay entered the market with a long-term vision not just to collect payments, but to empower businesses to scale, simplify operations, and succeed in a digital-first economy.
“We didn’t build OnePay to follow the market we built it to lead,” said Amila Fernando,
Co-Founder of OnePay. “Our approach is simple: infrastructure first, trust always,
and continuous innovation. Today, we’re proud to be powering everyone
from micro-entrepreneurs to enterprise merchants across Sri Lanka.”
