Microsoft 365 vs Perpetual Licensing: What's Right for You?

Perpetual licenses (like Office 2021) are a one-time purchase — attractive on paper, but they miss out on continuous updates, cloud storage, and the security features bundled with Microsoft 365.

Microsoft 365 Business Premium adds Defender for Office 365, Intune device management, and Azure AD P1 — capabilities that typically cost far more if purchased separately.

For most organizations, Microsoft 365 on a CSP subscription is the better value: predictable monthly cost, always-current software, and licensing that scales up and down with headcount.
