The Challenge

Enterprise payment processing platforms handle billions in transactions, but customers use different ERP systems (NetSuite, QuickBooks, Intacct). Manual data entry was causing:

8+ hours weekly on manual reconciliation per customer
3% error rate in financial data entry
2-day lag in financial reporting
Customer churn due to integration friction

The Solution

Built a real-time, event-driven synchronization platform that:

Smart Data Mapping

AI-powered field mapping that learns from user corrections, reducing setup time by 80%

Real-time Sync

Event-driven architecture syncs changes in under 100ms using webhooks and queues

Error Recovery

Automatic retry logic with exponential backoff and dead letter queue processing

Conflict Resolution

Intelligent merge strategies for concurrent updates with audit trail
