Inventory Planner

Inventory Planner by Sage is a demand forecasting and replenishment platform built for ecommerce retailers and wholesalers that need to plan purchasing across multiple sales channels and stock locations. The software generates automated reorder recommendations, forecasts customer demand using historical sales data, and helps merchants manage inventory spread across Amazon FBA, owned warehouses, and third-party logistics providers.

The tool fits into the planning and purchasing side of an Amazon seller's workflow, sitting alongside Seller Central rather than replacing it. Its focus is demand forecasting, reorder planning, open-to-buy budgeting, and multi-location stock visibility, with less emphasis on day-to-day listing, PPC, or reimbursement tasks. Sellers running meaningful volume across Amazon plus other channels such as Shopify or BigCommerce tend to benefit most, while smaller single-channel sellers may find the feature set broader than they need.
