The Supply Planning Manager is responsible for translating sales forecasts and demand signals into executable replenishment, inventory positioning, and distribution plans across the company’s distribution network. This role ensures the right product is available, in the right quantities, at the right locations, and at the right time — while balancing inventory investment, warehouse throughput capacity, labor availability, and transportation constraints.

This position plays a critical role in aligning demand with operational capability across distribution centers. The Supply Planning Manager partners closely with Sales, Demand Forecasting, Operations, Warehouse, and Traffic/Logistics teams to drive service level performance, minimize stockouts, reduce excess inventory, and optimize working capital.
