The Challenge

The development of our client’s new website created a need to also build a new billing gateway. The client already possessed a reliable, proprietary legacy billing application that was at the core of their back-end operations, but was running without web integration. In addition, several security considerations would need to be addressed as it became necessary to "break" portions of the legacy system to create the new gateway. Kalles Group was tasked with managing the of development a new billing gateway that would bridge the gap between the client’s billing application and its internet-facing customers.

Our Approach:

The completion of the gateway would need to coincide with the completion of the new website. The new billing gateway would also need to function smoothly despite the difficulties associated with altering an older application that was designed without considering web integration. Kalles Group provided a program manager to:

  • Oversee the design and implementation of the new gateway
  • Aid in nalizing the functional scope of the tool
  • Integrate with the security team to repair vulnerabilities and mitigate overall risk
  • Track the interconnections across disparate portions of the project
  • Drive risk management process and activities
