connecting quickbooks and shopify products/stock

So I have already connected my Shopify to quickbooks via the quickbooks online global app. I would like to be able to automatically have my stock reduced by 1 every time I sell a product. My products are hampers that are made up of different items. On quickbooks I have uploaded the different items as stock, and created bundles (which are the hampers) including all the of the stock items in that hamper. How do I manage it so that when that hamper on Shopify sells, that it is connected to that corresponding bundle on quickbooks, to reduce my stock for all those items?
