Sterling Trust Bank – Digital Customer Onboarding Transformation

FINTECH/ BANKING AND FINANCIAL SERVICES

Role: Business Analyst

Agile Scrum

Project Overview

Sterling Trust Bank (STB), not the real bank name, for confidentiality reasons. One of the UK’s top five financial institutions, serving over 25 million customers, embarked on a significant digital transformation programme to modernise its customer onboarding journey

Despite strong digital capabilities, the bank experienced a 35–40% drop-off rate during onboarding, particularly at the document upload and compliance verification stages

Customers lacked visibility into application progress, integrations between systems were inconsistent, and manual checks created bottlenecks that slowed verification and reduced customer satisfaction

This project aimed to streamline the onboarding experience, improve operational efficiency, and reduce onboarding time to under 10 minutes while ensuring complete alignment with UK financial regulations

Business Challenge

STB faced several systemic issues impacting onboarding performance

Fragmented systems (Salesforce, OpenText, FLEXCUBE, Refinitiv) with limited real-time integrations

High document rejection rates due to poor validation and manual re-entry

A lack of customer transparency can lead to frustration and abandonment

Compliance backlog caused by false positives and manual case reviews

Operational inefficiency, leading to lost deposits and missed revenue opportunities

These issues created friction across the onboarding process and weakened customer acquisition efforts
