Best Inventory Optimization Software in 2026
Planning stock across sites or supply-chain stages calls for comparing how software supports inventory decisions. Look at multi-location and multi-echelon optimization, replenishment recommendations, safety stock optimization, and service-level targets. Scenario planning can also matter when evaluating plans against different assumptions. Free-plan availability and paid-from pricing help put access and cost in context. ZebraDesigner, Manhattan Active Inventory Replenishment, and 4R Systems Intelligent Inventory Optimization are among the options shown, along with Bluemingo Production Planning & Scheduling. Consider which planning capabilities match your team's inventory needs.
