Case Study: Caisse des Dépôts et Consignations achieves unified finance and up to 70% operational cost savings with CCH Tagetik

Caisse des dépôts et consignations - Customer Case Study

Caisse des Dépôts et Consignations (CDC) is a French state-owned group with some 6,400 employees and diverse subsidiaries across investment, savings, pensions and property management. Faced with highly varied business and reporting rules, multiple legacy systems and the need for enterprise-wide consolidation, CDC sought a single, flexible financial platform that could import disparate data, provide detailed audit trails, let each entity maintain its own rules, and be operated internally without outsourcing.

CDC selected Tagetik and rolled it out in phases, configuring entity-specific planning, consolidation, costing and reporting before handing day-to-day maintenance to its own team. The unified platform delivered a single source of truth and automated auditing while preserving local flexibility, eliminated most manual processes and seven legacy systems, and achieved major efficiency gains—reducing data processing time by up to two-thirds and cutting operational costs by 50–70%—with rapid user adoption thanks to familiar Excel-based interfaces.
