This is one of the more important Excel spreadsheets I have been looking to build for a while now and I am really happy with the way it turned out. Product + Service, just means you sell a product (such as an elliptical machine or some tangible product for a one time fee) and you attach a paid subscription service add-on to it. There are many examples, such as adding fitness trainers that come on the screen of your elliptical or a security monitoring system.
