The client

WayThru is a US-based fintech multi-tenancy platform aimed to help debt managing companies operate efficiently, helping schedule debts using various payment providers. The company’s ethos is rooted in humanity, focusing on a modern, empathetic approach to debt recovery.

The challenge

WayThru faced several technical and operational challenges with their previous third-party payment gateway processor:

The platform's rigidity resulted in prolonged processing times, often extending to months, which significantly delayed the integration of new customers.

Relying heavily on a third-party service that operated as a closed system, WayThru faced potential security vulnerabilities and operational limitations.

The API provided by the payment processor lacked essential endpoints, hindering the development of a seamless user experience.

The middleware was limited by the range of available payment options.

The cost associated with using the previous payment system was notably high, impacting the overall financial efficiency.

What was done

Addressing the challenges with WayThru’s previous payment system, our team dedicated 12 months to developing a payment middleware solution from scratch. Designed to efficiently integrate with a range of third-party payment services, significantly improving the platform’s overall functionality.

Implemented features:

Platform connections to external payment providers, enabling support for various payment methods.

Efficient transition of the users from their previous payment systems to the new middleware.

Functionality for scheduled payment reminders.

3-D secure authentication processes from payment providers to enhance transaction security.

Compliance with CCPA, PCI DSS and other relevant regulations and standards.

Ongoing security tests, vulnerability analysis, and external penetration testing.

Additional features

REST Endpoints and WebHooks: Added new RESTful endpoints and WebHooks to ensure efficient and reliable communication between the platform and external services.

Strong Unit Test Coverage: Maintained a robust unit test coverage of 80% or more, ensuring high reliability and stability of the platform.

Automated Quality Assurance (AQA): Employed Automated Quality Assurance techniques for comprehensive end-to-end and integration testing, which helped in maintaining the overall quality and performance of the platform.
