National Grocery Chain WMS Cloud Migration, Achieves 99.8% Inventory Accuracy at Scale

About the Client

The client is a $15B national grocery chain operating 68 distribution centers across multiple regions. Their existing Manhattan WMS struggled to handle peak demand, impacting fulfillment speed and inventory visibility. Performance bottlenecks and limited scalability affected operational efficiency during high-volume periods. To modernize their supply chain and support growth, the organization partnered with Zymr.

Key Outcomes

99.8% Inventory Accuracy Achieved
42% Increase in Picking Productivity

Business Challenges

The organization faced significant performance issues with its legacy WMS during seasonal and promotional peaks. System slowdowns impacted order processing speed and reduced warehouse efficiency. Inventory inaccuracies led to stock mismatches, affecting customer satisfaction and store replenishment.

Operational complexity increased with the scale of 68 distribution centers, making it difficult to maintain real-time visibility across locations. Manual interventions and limited automation further slowed down picking, packing, and shipping workflows.

Additionally, the existing system lacked flexibility to integrate with modern robotics and automation technologies. Scaling infrastructure to meet growing demand was costly and inefficient. The business required a cloud-native, scalable solution to improve performance, accuracy, and operational agility.
