With operations spanning more than 60 countries and over 1,400 bank accounts, The Adecco Group faced growing complexity in managing payments, liquidity, and compliance. Legacy systems operated in silos, limiting visibility and increasing operational risk made global coordination increasingly difficult. To modernize treasury and prepare for ISO 20022, Adecco partnered with TIS — transforming its fragmented landscape into a streamlined, centralized model.
Fragmentation at Global Scale
The Adecco Group’s treasury function had to support a highly decentralized business landscape — with each region managing its own systems, banking relationships, and processes. This local flexibility came at a cost. At a global level, complexity continued to grow — making it harder to maintain control, visibility, and consistency across the organization.
Key challenges included:
- Disconnected systems across regions and business units
- Limited visibility into global cash positions
- Increasing compliance pressure (ISO 20022, regulatory demands)
- Complex bank landscape with inconsistent standards
ISO 20022 Without Disruption
Instead of updating hundreds of internal systems, Adecco took a different approach. By leveraging TIS as a central transformation layer, the organization was able to manage ISO 20022 requirements without disrupting existing operations. Legacy payment files flow into TIS and are automatically converted into ISO 20022 formats, while bank-specific requirements are handled centrally — with no changes needed in source systems.
Results include:
- Connectivity to 35+ banks worldwide
- Management of 1,400+ bank accounts
- Integration with 100+ internal systems
- 800+ users on a centralized platform
- Full ISO 20022 readiness without system overhaul
By centralizing payments, connectivity, and data transformation, Adecco established a future-proof treasury model — ready for evolving standards, regulations, and growth.
