About the Douplo
Douplo keeps inventory stock matched across duplicate listings automatically. When you sell the same item under two different listings, their stock counts can drift apart. This app links variants by SKU and barcode so inventory stays synchronized, even across different products.
Before any link activates, you see each variant's stock levels before and after at every location. Nothing starts until you confirm. If you change your mind, new links can be undone within 2 minutes if stock hasn't moved yet.
The app runs daily checks on all active links and only touches inventory data. You get low-stock alerts directly in the app, plus up to 90 days of history to track changes. Douplo finds potential matches automatically, but you decide which variants to link. Perfect for stores managing the same item across multiple product listings or locations.
