About StockTwin

Selling the same product under multiple listings, photos, or collections? StockTwin links every variant that shares a SKU or barcode and keeps their inventory perfectly in sync across all your locations, in real time. When one sells, the rest update instantly, so you never oversell or show wrong stock counts again. Set it up in under a minute: one scan finds every duplicate, and StockTwin handles the rest automatically. Includes bundles & kits, low-stock alerts and discrepancy detection.
