Key Facts
Slack and Microsoft Teams have converged on core features — channels, threads, video calls, file sharing — so the decision usually comes down to what your organization already uses and how your teams work day to day.
Slack's strength is its interface speed and its integration directory. With over 2,400 apps in its directory, nearly every SaaS tool your team uses — from project trackers to deployment dashboards — posts notifications into channels where they become actionable. The workflow builder lets non-technical users automate routine messages without IT involvement. Channels are searchable across the entire workspace history, and thread-based conversations keep side discussions from burying the main channel. Slack costs $7.25 per user monthly at the Pro tier.
Teams costs $4 per user within Microsoft 365 Business plans — often effectively free because most enterprises already license it. Its depth comes from Office integration: co-editing a Word document inside a Teams meeting, scheduling calls from Outlook, and OneDrive file sharing happen natively. For organizations of hundreds of employees standardized on Microsoft infrastructure, Teams' compliance tooling, admin controls, and included meeting capabilities make it the pragmatic choice. The tradeoff is a heavier interface and slower search.
The practical split: startups and product teams typically prefer Slack for its responsiveness and the way integrations turn channels into operational dashboards. Enterprises on Microsoft 365 get more total value from Teams, since paying separately for Slack on top of Office licenses duplicates spend. If your team runs on Google Workspace or mixed tooling, Slack's integration advantage is decisive. Many organizations end up using both — Teams for company-wide meetings, Slack for engineering and product work — which works but doubles notification management.
