Modernizing B2B Client Onboarding: Lessons from Fintechs for Commercial Banks

In today’s rapidly evolving financial landscape, commercial banks face a pivotal challenge: how to deliver seamless, efficient onboarding experiences for business clients. As fintechs and digital challengers redefine what’s possible—reducing onboarding times from weeks to hours—incumbent banks must transform or risk losing market share and relevance. Here, we explore how fintechs are revolutionizing B2B onboarding, the business impact of seamless onboarding, and how Publicis Sapient is helping commercial banks lead the next wave of digital transformation.

The Stakes: Why B2B Onboarding Matters More Than Ever

Commercial banking is on the cusp of unprecedented growth, with global revenues projected to reach £3 trillion by 2026. This surge is driven by an expanding commercial client base and a growing demand for frictionless digital experiences. Yet, for many banks, onboarding remains a significant pain point. Industry surveys reveal that 67% of business clients cite Know Your Customer (KYC) and onboarding processes as the biggest barriers to starting a new banking relationship. The result? Over half of commercial clients are actively reconsidering their banking partners, and banks are losing billions annually due to onboarding inefficiencies and compliance challenges.
