Demand Planning

Demand planning forecasts how much of each product you'll need and recommends what to reorder, so you can turn a forecast into purchase orders in a few steps. You work on Inventory → Demand Planning: build a forecast from sales history or target stock levels, then choose a baseline method that follows a product's growth or decline, check how far to trust each number, clean one-off spikes out of the history, plan for promotions, and run the forecast on a schedule. The Inventory Planning report gives you the same reorder view across every supplier at once. The same page plans what to make as well as what to buy, with the ingredients your builds need ordered alongside, and shows FBA units Amazon has misplaced that are likely to come back.
