Removing the complexity from global HR transformations.

Who We Are

Charlton Shaw Ltd. is a boutique technology consultancy specializing in high-impact global HR transformations, rapid global roll-outs, Post-Merger Integrations (PMI), and divestment strategies. Led by Shaun Henry, a Global SAP HCM & Integration Consultant with over 20 years of experience, we provide deep, specialized expertise without the bloated overhead of a massive firm. Operating globally with a presence spanning the UK, Portugal, and Brazil, we bring a highly personalized, hands-on approach to enterprise-level challenges

The Boutique Advantage

The Boutique Advantage Many large "Big Four" consultancies rely on a one-size-fits-all approach, which is driving a growing market appetite for agile firms that can bring fresh, tailored ideas. We purposely remain a specialized, boutique consultancy because trying to serve every client size and need only dilutes the quality of the service. By focusing strictly on complex global HR architectures and data migrations, we ensure that you get dedicated senior expertise and customized solutions, rather than being handed off to a junior team. At Charlton Shaw Ltd., we believe that technology must serve the business—not the other way around.

Mergers, Acquisitions & Divestments: Navigating complex global HR data migrations, managing strict compliance, and executing smooth employee transfers across borders.
Global System Harmonization: Designing global templates and consolidating fragmented landscapes into single, unified HCM solutions.
Solution Architecture & Integration: Deep technical specialism in SAP HCM, Ceridian Dayforce, and Workday across cloud, on-premise, and hybrid platforms.
