The Best Inventory Planner Alternative for Shopify

Inventory Planner by Sage focuses on demand forecasting, purchase orders, and multi-channel sync (Amazon, WooCommerce, QuickBooks), priced on request. Stockful focuses on inventory visibility - daily snapshots, 100+ 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 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.

On published pricing, yes. Stockful starts at $19.99/mo with a 14-day free trial, and every plan includes every feature - no feature gating, no hidden costs. Inventory Planner does not publish a price for its main product; you request a quote, and Sage says pricing is based on the volume of inventory you manage. The only figure Sage lists publicly is $119.99/mo for Inventory Planner Essentials, a single-warehouse, Shopify-only plan.

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

Yes. Stockful builds the order for you: reorder recommendations group into one draft per supplier, priced from that supplier's list, and you send it as a branded PDF or by email. Receive stock as it arrives with partial receipts, then let shipping, duties and fees allocate across units for a true landed cost that feeds your margins. The difference is breadth: Inventory Planner covers multi-channel PO management across Amazon and other channels, while Stockful's purchasing is built around Shopify and Shopify POS.

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.

Inventory Planner turns your data into a large metric set you can pick columns from and save as a preset, and it emails reports on a schedule. Stockful ships 100+ built-in reports that run live, plus a builder where you choose metrics, dimensions, filters and a chart. Every report is also a StockfulQL query you can read and edit. The other difference is where a scheduled report can land: Inventory Planner delivers by email, while Stockful also delivers to Slack, a webhook, Google Sheets or Airtable.
