Microsoft is making some pretty significant changes to PowerApps and Flow licensing starting on October 1, 2019. The details of these changes have been trickling out since the initial announcement in mid-July at the Inspire conference.
July 16: The Inspire session where the licensing changes were first announced: Microsoft Power Platform business model and licensing updates.
July 25: A post on the PowerApps blog from Charles Lamanna summarizing what what covered in the Inspire session: New licensing options for PowerApps and Microsoft Flow standalone paid plans.
August 29: A summary similar to the Charles’ blog post on the Microsoft licensing site: Updates to Microsoft 365, Dynamics 365, PowerApps and Flow Licensing.
August 29: A FAQ with additional information about the licensing changes: PowerApps and Microsoft Flow licensing FAQs for October 2019.
There are two things to note here: 1) the official documentation on PowerApps and Flow licensing has not been updated yet, and 2) the information contained in the above resources has evolved since July. The point I’m trying to make is that there is a chance that the licensing rules may not have reached their final state.
