Enterprise demand planning

Restock vs Inventory Planner

Both tools forecast demand and flag what to reorder — but they're built for different stores. Inventory Planner is an enterprise-grade, multichannel planning suite; Restock is a free-to-start, Shopify-native tool that gets you to a reorder plan in minutes. Here's an honest, side-by-side look.

What Inventory Planner is

Inventory Planner, owned by Sage, is one of the most established demand-forecasting and replenishment platforms in ecommerce. It connects Shopify, marketplaces, ERPs, and 3PLs, generates purchase orders, and supports open-to-buy and vendor planning — aimed at scaling and enterprise brands that plan inventory as a full-time job.
