Case Study: Veolia achieves fast, accurate payroll outsourcing with Ascender's Preceda

Veolia transforms its payroll with Ascender

Veolia, the global water-services leader with around 200,000 employees across diverse roles, faced a complex payroll challenge in Australia and New Zealand: moving from an in‑house payroll model (Ascender PAY ANZ) to an outsourced solution under a tight timeline, with a small project team, complex pay rules and the need for seamless, error‑free data migration. Ascender was engaged as the vendor to advise and manage the transition.

Ascender recommended and implemented the outsourced Ascender Preceda solution, taking on data migration, parallel testing, system configuration and ongoing management. The migration was planned for just 10 weeks and delivered fast, automated payroll processing with 24/7 access; Veolia’s first parallel payroll run was 100% accurate, self‑service cut transactional HR time (addressing an estimated 30% of HR queries) and the move reduced monthly costs and payroll administration time, improving productivity and compliance under Ascender’s management.
