Case Study: Building a Scalable Non-Profit Payment System with Venmo Integration

When faced with the sudden shift to virtual fundraising during COVID-19, our client—a leading non-profit in the healthcare industry—needed a modern, flexible donation platform to meet donor expectations. Their legacy system couldn’t keep up with the demand for new payment integrations, such as Venmo, which had to be implemented before a crucial virtual fundraiser. Clear Function delivered a scalable, modern payment processing platform, complete with seamless Venmo integration, all within the required timeframe.

Our client faced challenges with a rigid legacy payment system that couldn’t keep up with the rapidly changing demands of virtual fundraising and digital payments. Integrating new payment methods took 6 to 12 months, preventing them from accommodating their donors' preferences. With COVID-19 in full swing, they urgently needed to implement a modern digital payment solution before an upcoming virtual fundraising event.

• Build a modern payment processing platform to replace the legacy system.
• Design the new platform to reduce the time required to adopt new payment methods by approximately 75%.
• Ensure fast and seamless integration of Venmo before the fundraiser.
• Empower the client’s internal tech team to manage the platform independently.

Clear Function developed a custom payment processing platform designed for flexibility and scalability. We worked with the client’s preferred tech stack, including .NET and SQL Server, to deliver a tailored solution. In addition to detailed platform documentation, we held weekly training sessions for developers to ramp up on the new tech stack, ensuring a seamless handoff of the application to the client once the project was completed for ongoing ownership.

Clear Function delivered a modern, scalable payment platform that dramatically reduced the time required for new payment integrations by approximately 80%.
