What’s the true cost difference between Microsoft 365 Business Premium and Enterprise E3/E5?

The sticker price is just the beginning. Business Premium ($22/user/month) appears cheaper than E3 ($36/user/month) or E5 ($57/user/month), but the security limitations can cost you more long-term. Most Tampa businesses we audit are either overpaying for Enterprise licenses they don't fully utilize or facing security gaps with Business plans that lack critical protections. Our Microsoft 365 license optimization identifies the perfect mix for your specific needs, sometimes implementing hybrid licensing models that deliver Enterprise-grade security without the enterprise price tag.
