Towards the end of 2019, Microsoft announced the ability for users to “self-serve” when it came to purchasing Power Platform licenses. This allowed users to buy licenses directly in the portal, circumventing central IT although, after much kerfuffle, Microsoft made it possible for organisations to turn off this feature.
Microsoft have now added Project & Visio Plan 1 & 3 licenses to the self-serve roster – clearly this is a purchasing channel they’re keen to continue exploring. In several areas, Microsoft appear to be slowly moving towards more direct sales models, a la Salesforce, and this is part of that approach – building up loyalty and customer stickiness among the users, regardless of what the overall company stance may be.
