When the same product is listed under multiple SKUs, barcodes, or locations, stock levels drift apart and you end up overselling. StockTwin keeps every matching variant in sync automatically whenever stock changes, an order is placed, or a refund is issued, all matching variants and locations are updated to match. Bundles are supported too: selling a kit deducts each component from its own listings. Works for catalogs of any size, across one location or many.

• Sync stock across duplicate SKUs and barcodes in real time
• Sell bundles and kits without overselling their components
• Reserve safety stock for wholesale and off-channel sales
• Bulk sync hundreds of SKUs, import/export setup as CSV
• Exclude products, locations, vendors or tags from syncing
