Case Study: Shamir Optical achieves 25% inventory reduction while maintaining 99%+ service levels with ToolsGroup SO99+

From zero visibility to night vision

Shamir Optical, a global eyeglass lens manufacturer, faced a decentralized, siloed supply chain with poor visibility and high stock levels needed to protect 99% service targets across some 200K SKU-locations. Seeking a specialist inventory optimization solution rather than a generic ERP, Shamir selected ToolsGroup’s SO99+ (implemented with partner Rasner) to gain network-wide demand planning, fulfillment and replenishment control.

ToolsGroup implemented a single on‑premise SO99+ instance, integrating data and ERP interfaces and centralizing planning; within months the solution enabled multi-echelon optimization and rapid scaling. As a result ToolsGroup helped Shamir cut inventory by 25% while maintaining 99%+ service levels, reduce average stockouts from 600–700 SKU‑locations to under 200, and run a much larger network with the same number of planners.
