Inventory optimization software supports planning decisions about stock, replenishment, and service goals.

These criteria can help you focus on the structure of your network and the planning choices your team needs to make. Free-plan availability and paid-from pricing add cost context. Manhattan Active Inventory Replenishment, o9 Digital Brain, and Lokad are among the options to consider, alongside GAINS and Slimstock Slim4. Compare the planning capabilities with your operational requirements, including whether your inventory spans multiple locations or stages.
