Case Study: Synchrony Financial achieves core migration and customer experience transformation with Fiserv

Synchrony Bank Wins Celent Award for Core Banking Replatforming

Synchrony Financial needed to modernize its digital customer experience and grow low‑cost deposits while reducing dependence on monolithic legacy systems. To do that it partnered with Fiserv, migrating to the Fiserv Signature core and using Fiserv’s Enterprise Services Framework (ESF) as the foundation for a more open, API‑driven architecture.

Fiserv delivered the Signature core and integration support while Synchrony built a cloud‑native, microservices Business Services Layer (deployed on Pivotal Cloud Foundry) to orchestrate APIs and accelerate front‑end innovation. The program helped Synchrony increase direct deposits from $37.9B to $49.4B (~30% growth, 14.2% CAGR), lift total deposits to $64B, sustain a ~30.8% efficiency ratio, cut manual fraud alerts by over 30%, and enable much faster product launches — with Fiserv continuing to provide a dedicated integration team.
