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.

Stockful now also has native purchase orders: suppliers with full price lists, an order per supplier from your recommendations, sending by PDF or email, receiving with partial receipts, and true landed cost.
