Payroll scope includes base pay, commissions, bonuses, allowances, deductions, and other approved pay elements.
• Manage day-to-day relationships with ADP Celergo, assigned in-country payroll providers, and Employer of Record (EOR) providers; monitor delivery against agreed service levels; resolve operational issues; and escalate material service, compliance, contractual, or commercial concerns to the Global Payroll Manager.
