Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureLinkStock syncs products and variants that share physical stock. Use Stock Groups for duplicate listings, singles and packs, with explicit Units per sale. Connect existing set variants to component recipes with Bundles. Availability is calculated independently at each selected location. Review stock counts before confirming changes, preserve leftover units, and follow updates in activity history.
Selling your last unit twice turns one order into a refund and an apology. StockUnison keeps one stock count wherever that item sells. Sync two-way: every product with the same SKU shares one count, in one store or many, and each location you share keeps its own. Or sync one-way: one main store in charge, every connected store copies it. 100,000 variants are matched in about a minute.
- Link products and variants that draw from the same physical stock.
- Keep shared quantities aligned independently at each selected location.
- Review quantity conflicts, pause groups, and follow inventory activity.
- Match products across stores by SKU, with duplicates and gaps flagged
- Push stock changes from one source store to every connected store
- Preview every change in dry run before any inventory is written
- Check for drift at any time and reconcile stores back into agreement
