Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureHubStock syncs a network of stores from one master store. Stock lives on the master only — destination stores mirror it — so two stores never fight over the same number. Import your catalog, connect a destination store with a pairing code, then map your locations. Products that already exist there are matched by SKU and linked, not duplicated.
Highly configurable, real-time syncing, Synkro makes managing multiple stores a breeze. Clone your products to multiple connected stores and let Synkro keep everything in sync, saving you time and effort. Custom price rules allow you to automatically adjust product prices, enabling dynamic pricing strategies. Route orders placed in child stores back to the parent and sync tracking information.
