Objective
GSK embarked on a global payroll transformation initiative to unify its payroll operations across multiple regions under a single Workday Payroll system. The goal was to enhance accuracy, compliance, and visibility in payroll processing while reducing manual intervention and ensuring seamless integration with HR and finance modules.
- Validate end-to-end payroll processing across global entities
- Ensure accuracy of payroll calculations and statutory deductions
- Automate regression testing for multi-country configurations
- Guarantee compliance with local and international data protection standards
Solution
BTTIBD deployed a team of certified Workday Payroll consultants and test automation engineers to design and execute a comprehensive validation framework. The team implemented an automation-driven approach using Leapwork and Tricentis, enabling continuous testing and faster payroll validation cycles.
Key Deliverables
Rigorous parallel testing was performed against legacy systems to verify calculation accuracy and consistency. Data integrity checks were automated to ensure correct employee mapping, tax compliance, and end-to-end payroll reconciliation. Integration tests were executed across HR, finance, and time-tracking systems to guarantee synchronized data flow and performance stability.
Results
The global payroll implementation for GSK was delivered on time and within budget, achieving a seamless transition with zero critical post-go-live issues. Payroll accuracy improved by 38%, while automation reduced manual testing effort by 45%, significantly accelerating validation cycles.
The project enhanced compliance across all operating regions, ensuring strict adherence to local tax and labor laws. With a unified Workday Payroll platform, GSK now benefits from improved efficiency, data transparency, and reliable global payroll operations—backed by BTTIBD’s commitment to precision, compliance, and excellence.
