Visit Inventory Planner by Sage Alternatives

Inventory Planner by Sage is a cloud application for retail and e-commerce businesses that forecasts demand, generates automated purchase order recommendations, and reports on inventory performance across multiple sales channels and warehouse locations. It connects to e-commerce and marketplace platforms (such as Shopify and Amazon) as well as accounting/ERP systems, and was acquired by Sage, under whose brand it is now sold and marketed alongside Sage's broader small-business software line, including integration mentions of Sage Copilot/Sage AI. Compared with mid-market tools like Netstock or GMDH Streamline, Inventory Planner is scoped more narrowly at retail/e-commerce replenishment rather than full manufacturing S&OP or MRP. Pricing is usage-based on inventory volume with unlimited users included, quoted individually rather than published in fixed tiers.
