About Douplo
Same item, two listings? Link them so their stock stays matched. See every number before you link.
Same item, two listings, two stock counts that drift apart. Link them and Douplo keeps their stock matched, even across products. Douplo finds matches by SKU and barcode; you decide. Before a link starts you see each variant's stock before and after, at each location it covers, and nothing starts until you confirm. A new link can be undone for 2 minutes if stock has not moved. Every link that is on is checked daily, and Douplo touches inventory only. Low-stock alerts show in the app.

How Shoplist knows
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Douplo on a store, it is there.
- Counts are based on Shoplist's latest available public crawl signal dated November 1, 2026.
- Shoplist has not yet found reliable public storefront evidence connecting a Shopify store to this app. This does not mean the app has no users. Some apps are new, admin-only, server-side, theme-independent, or otherwise difficult to detect from public storefront signals.
- Merchant rows are filtered to public brand profiles with enough public data to link safely. Full workflow, filtering, and monitoring stay behind signup.
- Review, pricing, feature, screenshot, and listing-change data come from public Shopify App Store and Shoplist crawl records. Signals can change between crawls.
