What is the difference between multi-country payroll and international payroll management?

The terms are largely interchangeable — both refer to the process of managing payroll across multiple countries from a centralised system. "Multi-country payroll" is the more commonly used term in vendor and software contexts, while "international payroll management" is often used to describe the broader operational practice. In either case, the core requirements are the same: handling country-specific tax calculations, statutory contributions, currency conversion, and compliance obligations across all your operating markets.
