Which is better value?

Teams Essentials has the lower standalone list price. Slack may justify its premium where its workflow, integrations and partner collaboration fit better. If you already license a Microsoft 365 SKU that explicitly includes Teams, compare the incremental cost rather than assuming every Microsoft 365 plan includes it.

FAQ

Is Slack AI separately priced?

Slack’s current public plan page includes basic AI on Free and Pro and broader AI-powered work on Business+. The former separate Slack AI add-on pricing should not be added to today’s standard plan prices.

Is Copilot always included with Teams?

No. Copilot and Teams availability depends on the exact Microsoft license and bundle. Microsoft publishes both add-ons and bundled offers; verify the selected SKU.
