OneBill was founded in 2009 by JK Chelladurai, an OSS/BSS veteran and one of the founding team members of Portal Software which was acquired by Oracle in 2006, the first real-time billing and revenue management solution for telecommunications and internet service providers, such as Vodafone, France Telecom, Telstra, and many tier-1 telecom companies.

How Our Journey Started


I started working for Portal Software back in 1996 which provided an on-premise solution,  where customers had to invest millions of dollars to obtain a licence and then spend a few million more dollars to receive the actual solution. Therefore only very large companies had the resources to afford that kind of OSS/BSS solution. This created a significant barrier to other smaller service providers accessing a solution. So, we saw an opportunity to provide a flexible cloud-based, OSS/BSS solution for businesses of all sizes with varying needs.

At the time we launched OneBill, there were other billing solutions out there offering cloud-based platforms, but they were yet to infiltrate industries such as SaaS. Furthermore, these other solutions were focused on the billing needs of those offering purely subscription-based services. However, we were seeing that this ‘one-size-fits-all’ approach had limitations for other industries such as Communications, which have many nuances when it comes to billing and revenue management.

Minimizing revenue leakage and maximizing revenue assurance is one of the key aspects that we wanted to ensure as a billing and quote-to-cash system. And, we want to eliminate any manual steps in this whole quote-to-cash process and make sure that businesses don’t lose or they don’t leave the money on the table.
