The app syncs stock distributed across multiple locations.


Consider a scenario where 3 products ProductA, ProductB, and ProductC share the same SKU (they are physically the same item). Following is the location wise inventory distribution configured on Shopify:



LocationALocationBLocationCTotal
ProductA1050060
ProductB10104060
ProductC3001040


Let's say, an order is placed for ProductA for 20 units. Shopify will adjust the stock for product A as follows:



LocationALocationBLocationCTotal
ProductA10
30040


The Duplicate SKU Sync app will then force update the quantities of ProductB and ProductC to match productA for each location. The inventory distribution will look as below:



LocationALocationBLocationCTotal
ProductB10
30
040
ProductC1030040


The app assumes that the physical items are the same even if the product listings are duplicated. Hence, at all times, the stock levels should be the same across all locations.
