Automated Payment Processing Platform

The Challenge

A fintech startup needed a robust payment processing platform capable of handling both SEPA direct debits and card payments. The system had to support recurring billing cycles, automated reconciliation, and secure webhook processing - all while maintaining the reliability standards expected in financial infrastructure.

Our Approach

We built the platform around Stripe as the core payment engine, implementing a clean abstraction layer that unified SEPA and card payment flows into a single processing pipeline. Recurring billing was fully automated, with configurable schedules, retry logic for failed payments, and real-time status tracking.

Security was non-negotiable. All webhook endpoints were cryptographically verified, payment data was handled in compliance with PCI requirements, and the infrastructure was designed for high availability with automated failover. Every transaction flowed through auditable logging for regulatory transparency.

The Results

The platform achieved 99.9% uptime from launch, processing both SEPA and card payments through a fully automated pipeline. Manual intervention was eliminated for standard billing cycles, and the secure webhook architecture handled payment events reliably at scale - giving the startup a production-grade financial backbone to build its business on.
