A technical deep dive into our payroll data comparison algorithms that prevent £500K+ migration failures by catching conversion errors before go-live.
72% of payroll migrations experience data conversion errors. Most teams don't discover these until after go-live, leading to incorrect paychecks, compliance violations, and £500K+ recovery costs. VeriDiff catches these errors during the safe pre-load phase when fixes are still possible.
Upload your legacy payroll extract and converted data files (Excel/CSV). Files are processed in your browser - no data leaves your device during assessment.
VeriDiff intelligently maps fields between legacy and converted formats. Recognizes common payroll field patterns like "Employee_ID" → "EmpID" or "Gross_Pay" → "Total_Earnings".
Apply specialized validation: numerical tolerance for currency calculations, date format conversions, percentage calculations, and payroll-specific business rules.
Employee-by-employee, field-by-field comparison identifying: missing employees, salary discrepancies, incorrect deductions, misaligned benefit elections, and calculation errors.
