Case Study: Mazars USA achieves streamlined HR and payroll automation with Workday

Mazars USA gains key insights with Workday

Mazars USA, founded in 1921 and now a U.S. member of the Mazars Group, is a professional services firm with more than 900 U.S. employees offering audit, tax, and consulting services. Growing about 5% annually, the firm relied on paper files and manual HR processes that limited scalability, reporting, and access to employee records across locations.

Mazars deployed Workday (HCM, Recruiting, Benefits, Compensation, Payroll) to automate transactional work, enable self-service, and centralize data in a six-month implementation. Outcomes include a 90% reduction in manual entry, a 19% improvement in payroll staffing ratio (483:1 → 577:1), onboarding time cut to ~2.5 days with 80% of new hires completing paperwork before start, one real‑time system for accurate reporting, streamlined ADA/EEOC audits, and the ability to launch a diversity and inclusion initiative.
