VPCART does not control stock by product features.So if you have, for example, large blue shirts and small green shirts, VPCART will only keep track of the stock of the main product - shirts.
With inventory products, you set up a product record for the main product (parent product) – in this example, “Shirt”.
You can then set up a list of subproducts (child) that are associated with the main product – in this example, “Blue Shirt” and “Green Shirt”.
These subproducts are never shown directly when displaying products or searching, they are only seen when the main product is shown.They appear in much the same way as features.
