Case Study: Carrefour France achieves automated, optimized supply chain and 70% auto-validated orders with SymphonyAI GOLD Warehouse Replenishment & Instant Insight

Carrefour France Optimizes Supply Chain with SymphonyAI Retail CPG

Carrefour France, part of the Carrefour Group, faced an outdated mainframe-based replenishment system and sought to move from reactive to proactive supply planning, reduce manual order adjustments, cut inventory while improving availability, and deepen supplier collaboration. To meet these objectives it selected SymphonyAI and its GOLD Warehouse Replenishment & Instant Insight solution for a faster, scalable, data-centric replenishment and analytics platform.

SymphonyAI implemented GOLD through a design/build/test approach, double runs and phased rollouts (46 warehouses), with on-site support and trained power users; the system now auto-validates and reliably proposes orders so that more than 70% of orders require no modification (with a target near 80%), enables truckload and multi-pick optimization, calculates optimal safety stocks, reduces overstocks, frees planners for strategic work, and improved agility with suppliers during COVID disruptions—delivering measurable productivity and supply‑availability gains.
