Shared Stock lets you sync all your stores so you can manage them from one place. For example, if you have multiple language versions of your store, use Shared Stock to manage your main inventory across all store language versions.
Regardless of which store the customer will order from, after a purchase, the stock will be updated in all language versions. Save time and manage only one inventory, with its current status being automatically updated in all store versions.
Your whole inventory will be managed from one main store. Changes to the inventory in this once store will be reflected over all language version.
You can also sync prices, which is especially important when you have multiple language versions. The prices in the stores will be automatically converted to the currency you specified - no need to do it manually.
Note: In order for the app to work properly, it's necessary to have unique SKU's for all variants in your store.
