Global payroll transformation through automation, compliance enhancement, and Workday integration

Disparate local payroll providers

Background
GSK’s payroll and HR operations were highly decentralized, relying on disparate local payroll and Time & Attendance (T&A) solutions. This fragmentation led to manual inefficiencies, data inconsistencies, and compliance risks, causing delays, higher costs, and limited visibility into payroll data.
Despite using Workday for HRMS, payroll remained disjointed and manual, lacking seamless integration. GSK sought a reliable partner to consolidate operations, enhance compliance, and drive efficiency through automation and Workday integration.
