Power BI
Microsoft's flagship BI platform. The cheapest of the three by far ($14/user/month for Pro, free for individual desktop use), and the deepest integration with Excel, SharePoint, and the entire Microsoft 365 stack.
Pros
- Cheapest license of the three — $14/user/month for Pro, $20 for Premium Per User
- Native integration with Excel, SharePoint, Teams, and OneLake
- ECOSIRE Power BI Connector for Odoo ships with 50+ pre-built dashboards on day one
- Power Query for self-service data transformation
- Strong AI features (Q&A natural language, smart narratives, key influencers)
- On-premises Power BI Report Server option for sensitive data
Cons
- Tied to the Microsoft ecosystem — less ideal for Mac-heavy shops
- Visualization library is more limited than Tableau's
- Complex DAX learning curve for advanced calculated columns and measures
- Premium capacity (Power BI Premium) gets expensive at scale ($5k+/month)
