Multi-Country Payroll Migration
Scenario: Multinational technology company implementing ADP Workforce Now across 8 countries. Each country has different legacy systems, tax rules, and compliance requirements. Critical to validate currency conversions, local tax calculations, and statutory reporting data.
Post-implementation scenarios for operations teams maintaining payroll data quality and performing regular reconciliation tasks.
Period-over-Period Analysis
Operations team manually compares monthly payroll register against prior month to identify variances. Excel-based process takes 8 hours monthly and misses subtle changes in deductions, new hires, or calculation adjustments. No systematic way to track pay equity or benefits cost trends.
Automated month-over-month comparison of payroll registers. Employee matching by ID handles new hires and terminations. Variance reporting highlights pay changes, deduction adjustments, and benefits cost fluctuations requiring investigation.

Annual Enrollment vs Payroll Validation
After annual benefits enrollment, HR needs to verify that employee elections in the benefits system match deductions in payroll. Mismatches result in incorrect deductions, compliance issues, and employee dissatisfaction. Manual comparison across 5,000+ employees is error-prone and time-consuming.
Compare benefits enrollment export with payroll deduction file. Match employees across systems and validate that health insurance, dental, 401k contributions, and other elections are correctly reflected in payroll deductions. Exception reporting identifies mismatches for correction.
