First of all, you should calm down: You are in pleasant company! Particularly in the case of business models in which the customer scope plays an important role, the question of how money is earned is often not easy and can only be answered over time after several attempts. Of course, there are often clear answers to such questions: Sales revenues, for example, are clearly defined. For some recurring revenues, such as service sales for maintenance contracts, revenues from subscription contracts, but also franchise or annual licensing fees, the issue is often more difficult. Even more unclear is the situation when the users of your value proposition are not the ones who are supposed to pay for your offer, so they are not the actual customers. Questions then come to the forefront why someone should pay for something that she herself does not use.
