Coforge partnered with a global UK-based bank to modernize its payment processing ecosystem by eliminating dependency on third-party systems and improving operational efficiency. The existing setup relied heavily on a Temenos-based payment enrichment solution, resulting in high costs, delayed time-to-market, and operational inefficiencies.

By designing and implementing a custom, high-performance rule engine, Coforge enabled centralized payment routing, validation, and orchestration. The transformation improved scalability, reduced manual effort, and delivered a more efficient, user-friendly payment processing platform.

The Challenge

The bank’s payment processing environment was dependent on a third-party Temenos solution, which limited agility and delayed the rollout of new features and market expansions. High licensing and maintenance costs further impacted overall operational efficiency.

Manual intervention was required to manage payment exceptions, leading to inefficiencies and increased operational overhead. Additionally, the lack of an intuitive user interface made it difficult for operations teams to resolve errors efficiently.

The organization required a scalable, cost-effective solution to streamline payment processing, reduce dependency on external systems, and improve user experience.

Our Approach

Custom Rule Engine Development

Designed and built a proprietary rule engine from scratch to centralize payment routing, validation, and orchestration, eliminating dependency on third-party platforms.

High-Performance Payment Processing

Implemented socket-based, low-latency communication to handle high volumes of real-time payment requests efficiently.

Composable & Scalable Architecture

Developed a modular architecture enabling rule creation, persistence, and processing, ensuring flexibility and future scalability.

Exception Management & User Interface

Delivered a user-friendly interface for operations teams to configure rules and manage payment exceptions beyond Straight Through Processing (STP).

Operational Efficiency Enablement

Automated payment workflows and exception handling to significantly reduce manual intervention and improve processing efficiency.
