About the StockTwin

StockTwin keeps your inventory in sync across product variants that share the same SKU or barcode, preventing overselling and stock count errors. If you sell the same product under multiple listings, photos, or collections, this app links every variant and updates inventory in real time across all locations. When one item sells, the rest update instantly. Setup takes under a minute—one scan finds every duplicate SKU and barcode, then StockTwin handles syncing automatically. The app supports bundles and kits, ensuring component inventory stays accurate when selling multi-product sets. You can reserve safety stock for wholesale and off-channel sales, bulk sync hundreds of SKUs, and import or export your setup as CSV. Low-stock alerts and discrepancy detection help you stay on top of inventory issues. Exclude specific products, locations, vendors, or tags from syncing as needed.
