The best inventory & demand planning software

Inventory and demand planning software forecasts future demand and turns those forecasts into reorder points, purchase suggestions, and safety-stock targets so you buy the right amount at the right time. Most tools are a planning layer that reads from a system of record — your ERP or store — rather than running operations themselves. Endless is the exception: it plans inside the same system that holds inventory, orders, and purchasing.

It depends on your stack. Prediko suits Shopify-native brands, Cogsy is the affordable DTC all-in-one, and Netstock or StockIQ layer onto an existing ERP. Our pick is Endless Commerce for brands that want forecasting and execution on one source of truth, with transparent pricing, go-live in hours, and agents that act on the plan instead of just producing it.

Usually, yes. Tools like Netstock and StockIQ are planning layers that require a system of record — typically an ERP — underneath to hold the inventory, order, and cost data they plan against. Endless is different: it’s the system of record and the planning together, so there’s no separate ERP to buy, integrate, or keep in sync.

Demand planning forecasts how much you’ll sell, using history, seasonality, and trends. Inventory planning takes that forecast and decides what to stock — reorder points, safety stock, and purchase timing — to meet it without overbuying. Most modern tools do both, but weaker ones stop at a forecast and leave the buying decisions to you.
