I make bath and body products and offer them in a large variety of fragrances. For many of my products I create an bulk amount of unscented base and then add the customer's fragrance choice just prior to shipping.
Currently, with Shopify inventory, you have to add inventory for each variation of a product. For me, this can sometimes create overselling. Is there a way to set up inventory so that I can say I have 10 bottles of product X and then if someone wants 3 bottles in scent A, that would reduce my base inventory X without me having to fill in inventory for product X in variety A, Variety B, Variety C, etc. separately?
