The challenge

Outdated customer portal

The finance company we served in this project specialises in two areas:


  1. providing credit to customers who are new to credit or wish to rebuild their credit history
  2. extending its credit capability to global retailers in the form of white-labelled store cards


Prior to this project, the company relied on a legacy third-party platform to serve its online banking customers. The high cost of maintaining this third-party platform, along with its lack of flexibility and weak security, made it unsustainable.


Furthermore, the legacy banking platform’s unintuitive interface meant the company’s customer service team had to deal with frequent calls. It was clear that the legacy portal was having a negative impact on customer satisfaction and customer service efficiency.


For these reasons, the company decided it was time for online banking software development to rebuild the platform.

The solution

Online banking software development

The finance company already had the core of its new customer portal in place. Based on our reputation as portal experts, the company engaged us to deliver additional features and migrate the user base.


This core portal was split into over 19 customer-facing portals for the company’s different credit brands. Each portal had to have its own e-account management features.


Influential Software assisted by building the portal identity provider and a single sign-on (SSO) solution for all the client’s portals.


From there, we carried this online banking software development project forward by:


  • developing an Angular-based modern and intuitive front-end interface for users
  • ensuring government-grade security standards, FCA approval, and PCI compliance for all data
  • introducing automation into the software delivery process with industry-leading technologies
  • migrating the entire userbase — 9 million users — to the new in-house banking platform


Our seamless migration of 9 million users was the largest single software roll-out in the client’s history. Achieving this customer data migration without a hitch, we provided a seamless transition to the new online banking app.

The benefits

Delivering efficient banking software development

As a major part of the finance company’s new digital strategy, this customer portal development project brought the following benefits:


  • a massive reduction in customer service calls, thanks to the intuitive new interface
  • decreased risk and improved data security by bringing all user data in-house
  • accelerated software delivery through modern pipeline automation tools
  • reduced maintenance costs, and an application that could be easily adapted and extended


On the back of this customer portal, the finance company was able to quickly launch 19 brand-specific mobile apps. This allowed the company to open up its customer base even further.
