Our Verdict

Choose Slack if you prioritize a best-in-class messaging experience, work with many external partners, use diverse third-party tools, or want a communication platform that stays focused on chat and channels without feature bloat.

Choose Microsoft Teams if your organization already uses Microsoft 365, you need built-in video conferencing and file collaboration, want to consolidate tools into one platform, or need enterprise-grade security and compliance that integrates with Azure AD.

Frequently Asked Questions

01 Is Microsoft Teams cheaper than Slack?

Generally yes. Teams is free with Microsoft 365 subscriptions many companies already pay for. Standalone, Teams Essentials at $4/user/month is cheaper than Slack Pro at $8.75/user/month. For organizations already using Microsoft 365, Teams adds no extra cost.

02 Which has better integrations: Slack or Teams?

Slack has more third-party integrations (2,400+) and is often considered the integration leader. Teams has fewer native integrations but offers deeper Microsoft 365 integration including SharePoint, OneDrive, and Office apps. Choose based on your existing tech stack.

03 Can Slack and Microsoft Teams work together?

Yes, but with limitations. There are third-party bridges that sync messages between platforms, and both support common integrations. However, most organizations choose one as their primary platform to avoid fragmentation and confusion.

04 Which free plan is more generous: Slack or Microsoft Teams?

Microsoft Teams Free includes unlimited chat and 60-minute group meetings. Slack Free includes searchable message history for the last 90 days and 1-on-1 video calls. Teams Free is generally more generous for small teams that need video conferencing.

05 How much does Slack cost per user for a 100-person team?

For a 100-person team, Slack Pro costs $10.99/user/month ($1,099/month total) and Slack Business+ costs $17/user/month ($1,700/month total). Microsoft Teams Essentials would cost $4/user/month ($400/month total) for the same team size.

06 Does Microsoft Teams require a Microsoft 365 subscription?

No. Microsoft Teams offers a standalone free plan and a Teams Essentials plan at $4/user/month. However, the Business Basic ($6/user/month) and Business Standard ($12.50/user/month) plans bundle Teams with Microsoft 365 apps like Word, Excel, and OneDrive.
