How We Perfected Instant Banking With Google Cloud For India’s Top Private Bank

Case Study


The Client

A leading Indian banking and financial services conglomerate headquartered in Mumbai, Maharashtra that provides both corporate and retail customers with a wide variety of banking products and financial services

Project Objective

Being customer-centric at its heart, the bank envisioned re-engineering customer experience by introducing instant banking with end-to-end digital onboarding and account opening services. The key to this was to solve for legacy system shortcomings which accounted for long TATs , poor customer engagement and ultimately customer attrition.

The way forward was to improve the customer experience by leveraging cloud capabilities to provide seamless and instant banking services. And the bank collaborated with Niveus- India’s leading Google cloud solutions provider as the orchestration partner. We drive digital transformation across the BFSI landscape by empowering organizations to harness modern cloud-based banking solutions in India.


Solution Roadmap

  • The bank strategized to renew its customer onboarding experience and showcase all of its products on a single platform to address user experience, process inefficiencies, product offerings, and increase customer acquisition.
  • The bank decided to modernise the account opening process and move away from in-branch physical application methods.
  • The goal was to design and host a secure and scalable cloud based solution to help customers onboard and transact- quickly and conveniently.
  • The bank aims to leverage the digital enablers to improve and expand its product offerings.

Business Solution

  • Built a Progressive Web Application on Google Cloud Platform that integrates securely with the on-premises Core Banking APIs 
  • The new application enabled Instant Savings Account Opening and Fixed Deposit creation:
    While the legacy account opening process was time consuming and required the customers to travel to a physical branch, the new digital onboarding process allows customers to open an account in
    under 5 minutes* from anywhere, at any time, using any internet-connected device, with customers only having to input minimum details alongside their PAN and AADHAAR number.
  • Automated customer verification with V-KYC, document scanning and upload and E-signatures, following which the customer would have immediate access to transaction facilities.
