Best Inventory Optimization Software in 2026

Inventory optimization tools address decisions about stock, replenishment, and service targets across a supply chain. Compare multi-location and multi-echelon optimization alongside safety stock optimization and replenishment recommendations to see which planning needs each entry covers. Scenario planning and service-level targets offer more dimensions for evaluating inventory decisions, while free-plan availability and paid-from pricing provide access and cost context. ZebraDesigner, Lokad, and Creo lead the ranked entries, with supplychainpy also among the first options. Consider the structure of your inventory network and the decisions you need to make, then use the listed criteria to compare how each tool may fit those requirements.
