Project Insight Pro ($9/user) delivers budgeting, time tracking, resource visibility, and dashboards that Planner Plan 1 ($10) doesn't include without additional tools.
Project Insight Business ($19/user) gives you portfolio management, program visibility, intake, approvals, and governance—capabilities Planner Plan 3 ($30) requires Power Platform (Power Automate, Power Apps) plus custom development to achieve.
Project Insight Enterprise (≤$30/user) includes capacity planning, integrations with Jira and Azure DevOps, and executive reporting—features Plan 3 can only deliver by adding Power BI ($10-20/user), custom development, and integration setup.
For a 20-person PMO, Planner Plan 3 plus all necessary add-ons costs $40K-60K+ in year one. Project Insight Business costs $7,200. Enterprise costs $10,800. You're not paying extra for fragmentation.
