The Best Inventory Planner Alternative for Shopify

Inventory Planner by Sage focuses on demand forecasting, purchase orders, and multi-channel sync (Amazon, WooCommerce, QuickBooks) starting at ~$249/mo. Stockful focuses on inventory visibility - daily snapshots, 14 built-in reports, ABC analysis, Slack alerts, Shopify Flow integration, and health scores - starting at $19.99/mo with a 14-day free trial. Stockful also includes self-tuning demand forecasting: five candidate models per SKU and location, seasonality learned per product, and accuracy tracked continuously. If you need PO generation across multiple sales channels, Inventory Planner may be a better fit. If you need affordable inventory tracking, reporting, and alerts for Shopify, Stockful is built for that. Stockful now also exports its reorder recommendations straight to Shopify's native purchase orders (a CSV you import in the admin), so no separate PO tool is needed.

Yes. Stockful plans start at $19.99/mo with a 14-day free trial. Inventory Planner uses revenue-based pricing starting at ~$249/mo and requires a custom quote. All Stockful plans include every feature - there's no feature gating or hidden costs.

No. Inventory Planner focuses on demand forecasting and purchase orders, but doesn't capture daily stock-level snapshots at each location. Stockful records inventory levels per variant, per location, every day - giving you up to 2 years of historical data for trend analysis, velocity tracking, and sell-through rates.

Stockful turns your reorder recommendations into a purchase order for Shopify. Pick what to reorder, review the quantities and unit costs, and export a CSV in Shopify's purchase-order format that imports onto a new purchase order in the Shopify admin - items matched by SKU or barcode, supplier and tax set in Shopify. It isn't a standalone purchase-order or planning system: purchase orders live in Shopify, and Stockful feeds them. If you need multi-channel PO management across Amazon and other channels, Inventory Planner may still fit; if you want the reorder numbers behind a native Shopify PO, that's what Stockful does.

Stockful is built specifically for Shopify. It integrates deeply with the Shopify API and webhooks for real-time inventory tracking. If you need multi-channel inventory sync across Amazon, WooCommerce, or QuickBooks, Inventory Planner supports that. Stockful focuses on doing Shopify inventory analytics exceptionally well at a fraction of the cost.

Stockful takes under 5 minutes to set up - install the app, choose your locations, and data starts syncing immediately. Inventory Planner typically requires a ~4 week onboarding process with guided setup and configuration.
