Financial Services Firm Unifies 50+ Systems with Enterprise Integration Platform

A regional financial services firm serving over one million customers had grown through acquisitions over three decades. Each acquired company brought its own systems—different core banking platforms, CRM systems, document management solutions, and compliance tools. The result was a technology estate of 50+ major systems with limited integration and significant data inconsistencies.

The operational impact was severe. Customer onboarding required entering information into multiple systems manually. A simple address change might need updating in a dozen places. Customer service representatives toggled between six or more applications to answer basic questions. Compliance reporting was a quarterly nightmare, requiring weeks of data reconciliation before reports could be trusted.

Previous integration attempts had created point-to-point connections that became impossible to maintain. When one system was upgraded, multiple interfaces broke. The integration team spent more time fixing existing connections than building new capabilities. The architecture had become technical debt that constrained the business.

ELMET conducted a comprehensive assessment of the system landscape, data flows, and business processes. Rather than attempting to replace legacy systems—a multi-year, high-risk endeavor—the strategy focused on creating an integration layer that could connect any system while enabling gradual modernization.

The integration platform was built on cloud-native iPaaS technology with a central API gateway. Standardized connectors were developed for major systems, with a robust adapter framework for less common applications. The platform supported both real-time event-driven integration and batch processing, accommodating different system capabilities.

Master data management was implemented in parallel. The platform designated systems of record for key entities—customers, accounts, products—and implemented bidirectional synchronization to maintain consistency. Data quality rules identified and flagged discrepancies for resolution, gradually improving data integrity across the ecosystem.

Process automation built on the integration foundation. Customer onboarding, once requiring manual entry into multiple systems, was automated end-to-end. Information entered once flowed through orchestrated workflows, creating records in all required systems with full audit trails. What previously took days now completed in hours.

The compliance transformation was particularly impactful. With integrated data flows and centralized logging, regulatory reports that once required weeks of data gathering could be generated in hours. Real-time compliance monitoring replaced periodic batch reconciliation, reducing regulatory risk while freeing staff for higher-value activities.
