I don't see an option to track that the guest has prepaid for their products, should something be out of stock. This would be useful in tracking inventory. Along those lines, during special events, we create packages that sometimes include products. It seems we cannot add products to our packages. Please add products to the package options. There isn't a way to sell a prepaid service without creating a series, which creates more work. There should be a way in the purchasing screen where we can click that it is prepaid without having to create a series without it having to be so much work.
