Best Microsoft 365 alternatives in 2026

Microsoft 365 provides productivity applications and collaboration. Word, Excel, PowerPoint, and Teams-the suite that defines enterprise productivity. The applications are everywhere. The integration is deep.

Here are the real cost and limitation gotchas that push teams to look elsewhere:

• • Pricing increases hit July 1, 2026: Business Basic rises from $6 to $7/user/month (+17%), Business Standard from $12.50 to $14/user/month (+12%). Existing customers stay on current pricing until renewal.
• • Microsoft 365 Copilot (AI features) costs an additional $18-21/user/month on top of your base plan. It is not included in any standard plan and requires Business Standard or Premium as a prerequisite.
• • Business plans cap at 300 users. Organizations exceeding this must upgrade to Enterprise E3 ($36/user/month) or E5 ($57/user/month), a significant jump that often catches growing companies off guard.
• • Monthly billing costs 20% more than annual commitment across all business plans ($7.20 vs $6 for Basic, $15 vs $12.50 for Standard, $26.40 vs $22 for Premium). There is no month-to-month option for Enterprise.
