You are probably hearing about costs for the full Microsoft Dynamics 365 Apps. While everybody else would prefer that you buy those more expensive licenses, RapidStart CRM was designed to run on what is called the Power Apps Per App “platform” license, which is only $5. Microsoft recently separated their own first-party apps (Sales, Service, etc.) from the Platform that they run on, and made that same platform available for ISVs like us to build on. It’s one of those Win-Win situations.
