We are using Shopify for a wholesale website (www.G4Wholesale.co.uk) and accordingly are listing products with multiple case sizes. These differing case sizes are set up as variants of the same Product on Shopify. The issue we are having is with Inventory Management e.g. if a product has a case of 6 and a case of 1 then we would need to amalgamate the inventory albeit with it having the functionality to either take -6 or -1 away from stock depending on which variant is sold.
Could anybody advise of code, snippet or app that can do this please?
