What is Inventory Planner?
Inventory Planner by Sage is demand forecasting, replenishment, purchasing, and retail analytics software for ecommerce and multichannel businesses. It connects sales channels and operational systems so planners can forecast demand, identify stock risks, calculate replenishment needs, and prepare purchase orders.
Sage Copilot adds AI-assisted insights inside the planning workflow. The vendor says its Retail Intelligence Agent can highlight priority replenishments, overdue inbound items, missing cost prices, and other conditions that deserve attention.
Quick Verdict
Inventory Planner is best suited to established retail or ecommerce teams that need configurable planning across products, suppliers, and locations. It offers more operational depth than a lightweight reorder alert, but reliable recommendations depend on clean history, realistic lead times, stockout treatment, and disciplined planner overrides.

Our Take
Run a historical replay before accepting live buying recommendations. Include stable, seasonal, promotion-affected, stocked-out, and new products. Evaluate order dates and quantities in cash and service terms rather than trusting one catalog-wide accuracy score.
