Free Inventory Forecasting and Purchase Order Apps for Shopify
Shopify inventory planning apps with a free plan, and what the free plan includes. 10 apps, checked 2 November 2026.
How apps get on this list
The App Store listing or pricing page shows a free plan (not only a free trial or free install), and the listing states demand forecasting or purchase orders. Apps are listed by the number of Shopify App Store reviews on the date shown, highest first. Review count tells you how many merchants rated an app, not which app suits your store. We have not tested every app.
