Context & Profile

Lafayette Federal Credit Union, based in the Washington, D.C. metro (Rockville, MD), serves 50,000+ members with approximately $1.75 billion in assets. Its mortgage tech stack includes Corelation’s KeyStone core banking system and the Calyx Path mortgage loan origination system (LOS). To sustain growth and service quality, Lafayette needed these systems to operate in sync—without manual re-entry or delays.

Challenge

KeyStone and Calyx Path were not natively integrated. Staff had to re-key loan application data from the LOS into the core—and update the LOS when core data changed. This duplicate entry consumed hours, introduced errors, slowed post-closing updates, and created risk for reporting and audits. Lafayette required a reliable, near real-time bridge to keep records consistent across both platforms.

Solution with MortgageExchange

Lafayette implemented MortgageExchange, a cloud-managed integration platform from Mortgage Workspace (Access Business Technologies), to connect KeyStone and Calyx Path. The rules-based interface automates bi-directional data flow: loan application data from Calyx Path is mapped and written into KeyStone, while account and servicing updates from KeyStone synchronize back to the LOS. No interim spreadsheets or copy-paste steps—just a governed pipeline that validates and delivers the right fields to the right system.

Because MortgageExchange is cloud-managed, Lafayette avoided standing up new servers or custom code. Connectors are monitored and maintained by the provider; if vendors update KeyStone or Calyx Path, the integration is adjusted behind the scenes. Data in transit and at rest is encrypted, and the platform scales with loan volume—supporting growth without added IT burden.

Outcomes

  • Eliminated duplicate entry: LOS ↔ core synchronization removed manual re-keying and reduced clerical load.
  • Faster updates: Member records and loan statuses reflect changes in near real time across both systems.
  • Higher data accuracy: Rules-based validation cut typos and mismatches, improving overall record integrity.
  • Audit readiness & compliance: Consistent data across systems simplifies reporting and examinations.
  • Staff efficiency & cost savings: Time reclaimed from clerical work is redirected to member service and loan throughput.
  • Scalable & secure: Cloud-managed architecture grows with demand and keeps sensitive data protected.

Conclusion

By linking Corelation KeyStone and Calyx Path with MortgageExchange, Lafayette FCU turned a manual, error-prone handoff into a secure, automated workflow. The result is faster processing, cleaner data, and capacity to scale mortgage operations—so teams can focus on members instead of moving data between systems.
