Licensing

Hi Anonymous 

From what you've written, you'll need between 6 to 11 licences probably Power BI Pro. 

The issue with Power BI is that if you want to securely share Reports and Dashboards with users at this level, then each user needs a Power BI licence to view and interact with the content shared with them. 

You as the developer will need a Pro licence to create Reports and Dashboards, it's unlikely you'll need a Premium Per User (PPU) licence unless you have specific requirements or your data grows much larger. When you share those reports with others they will need a Power BI Pro licence to view and interact with them securely. (If you had a Premium Per User licence and used PPU facilities they would each need PPU licences.)

You can start with a Pro trial licence for 60 days before starting a monthly subscription, use this time to create a "proof of concept" and share it with others in your organisation who have a Pro trial licence. Then as you begin to see the benefits, you can purchase additional licences as required. The monthly subscription and trial licences mean you can start small and grow as the need arises. If you need a budget figure for the year plan on needing  a Pro licence for each person who needs to view and interact with a Report or Dashboard.

Hope this helps
