Tamilnad Mercantile Bank migrates from legacy systems to cloud with Oracle

Partners Deloitte for finance and CX and Kovaion Consulting for HR.

Tamilnad Mercantile Bank (TMB), an Indian bank headquartered in Thoothukudi, Tamil Nadu, migrates from legacy systems to Oracle Fusion Cloud Applications to modernise its finance, HR, and customer experience operations.

The bank standardises on Oracle Fusion Cloud ERP, HCM, and CX to unify core business processes, automate workflows, and embed AI across functions.

TMB aims to increase productivity, reduce costs, strengthen financial controls, and improve employee and customer experience.

Deloitte leads the implementation of finance and customer experience, while Kovaion Consulting manages the HR transformation as part of the Oracle Partner Network engagement.

Talking exclusively to CRN India, TMB’s executive vice president, Ramesh D, says the migration began in January 2025.

TMB completed the finance rollout in July 2025 and deployed HR in October 2025.

He adds that the customer experience (CX) implementation is progressing in phases and is on track for full completion by March 2026.

With Oracle Fusion Cloud ERP, TMB strengthens financial governance and automates key finance processes.

Oracle Fusion Cloud HCM enhances workforce management and delivers deeper workforce insights.

AI-powered capabilities, including the Leave and Absence Policy Advisor Agent, provide employees with real-time, personalised guidance on HR policies, reducing administrative workload.

Oracle Fusion Cloud CX supports improvements in sales efficiency and customer service delivery.

“As we reimagined how our bank operates and serves customers, we knew we needed a modern, agile and intelligent foundation,” said TMB’s managing director and chief executive officer, Salee S. Nair.

“Oracle Fusion Applications helped us consolidate systems and automate key business processes, improve insights, and build an AI-powered foundation to strengthen our operations. Oracle’s embedded AI and quarterly updates enable us to expand efficiently and better serve our customers,” he added.

Unified cloud stacks open opportunities

As competition intensifies in digital banking, TMB’s move to a scalable cloud platform reflects a broader shift among banks towards consolidating core enterprise applications on integrated SaaS suites.

The transition from fragmented legacy systems to a unified cloud stack opens opportunities for partners to drive process re-engineering, AI enablement, data integration and long-term managed services, as banks prioritise operational efficiency and scalable growth.

“As customer expectations continue to evolve, long-established banks must modernise how they operate while safeguarding the trust and relationships they have built over decades,” said Oracle India’s vice president of cloud applications, Shailesh Singla.

“With Oracle Fusion Applications, TMB is harnessing embedded AI to streamline finance, HR, sales and service to drive productivity and elevate the employee and customer experience. This demonstrates how AI can empower a time-honoured organisation to evolve confidently for the AI era,” he added.

TMB is also upgrading its internet banking platform in collaboration with EdgeVerve, a subsidiary of Infosys.

The bank plans to roll out over 170 services under the new internet banking solution later this month.

This will strengthen the bank’s digital delivery capabilities and support an integrated customer experience across channels.
