Slack vs Microsoft Teams

Slack and Teams are both team chat. Teams is bundled with many Microsoft 365 plans and includes meetings. Slack is a separate product that connects to a lot of other software. The right one is usually the one your files already live next to.

Slack

Strengths

Channels and threads are the product people mean when they say team chat
Connects to a wide set of tools outside Microsoft
Easier to keep a contractor or a client in a shared channel
Search and huddles cover a lot of quick conversations

Weaknesses

Meetings are not the reason to buy it; you still want a meeting tool
A paid Slack plan on top of Microsoft 365 is a second bill
File storage is not a replacement for Drive or SharePoint

Microsoft Teams

Strengths

Included with many Microsoft 365 business plans you may already pay
Meetings, chat, and Office files in one app
The practical choice when the company is on Outlook and SharePoint
One login for the people who already have a work Microsoft account

Weaknesses

Chat is noisier and harder to keep organized than Slack
Outside guests and non-Microsoft tools take more setup
The app does more than chat, which makes the simple thing slower

🏆 Winner

Teams if you already pay for Microsoft 365

Stay on Teams if the company already has Microsoft 365 and people meet in Teams today. Pay for Slack if chat is the actual workplace and the rest of the tools are not Microsoft. Running both means every conversation happens twice. Check whether Teams is already included before you add a Slack bill.
