Do you think fast core banking integration is impossible without a risky “rip-and-replace”? Think again. One financial institution proved it’s achievable, going live with Fimple’s composable platform in just 60 days. This integration delivered modern functionality while perfectly preserving their existing workflows and infrastructure.
The Challenge: Modernize at Market Speed
The institution needed to launch new digital products rapidly. However, their legacy system, with its custom SSO and proprietary accounting rules, posed a significant hurdle. Furthermore, the industry standard 6–9-month timeline was unacceptable. They needed a fast core banking integration that was both deep and non-disruptive.
Our Solution: Composable Architecture as the Accelerator
Fimple’s composable framework was the key to this fast core banking integration. Instead of forcing cumbersome custom code, we leveraged a flexible integration layer. This approach handled all the complexity externally.
Consequently, we achieved seamless integration in three critical areas:
- Authentication: We embedded our UI directly into their existing platform, enabling a seamless Single Sign-On (SSO) experience.
- Data Mapping: We dynamically transformed their customer and account data to fit Fimple’s schema without altering our core.
- Accounting Logic: We mapped our internal accounting templates to their external rules, ensuring financial consistency.
The Result: Transformation Without Disruption
The institution achieved a production go-live within the aggressive 2-month deadline. Most importantly, this fast core banking integration provides a future-proof foundation. They gained modern capabilities without sacrificing their existing investments, setting a new standard for rapid digital transformation in banking.
