See every featureOOS Tracker helps merchants understand how long products are unavailable due to zero inventory. It automatically records out-of-stock events when inventory reaches zero and tracks their duration until restocked. The dashboard prioritises the longest stockouts first, making it easy to focus on the most impactful issues. All products are monitored automatically, with clear visibility into ongoing and past stockouts.
Stockpilot tells you what to reorder and when, so you stop guessing from a spreadsheet. It forecasts demand for every SKU from your sales history, works out how many days of stock are left, and flags products before they run out. Select what needs reordering and it drafts purchase orders grouped by supplier, using each vendor's lead times and minimum order quantities. Receiving stock updates Shopify inventory.
