30-Second Answer for Small Business

Microsoft Teams wins for small businesses that already use Microsoft 365 because it is included free and covers chat, video, and file sharing in one app. Slack wins for small businesses using Google Workspace or a mix of tools that need deeper integrations.

Small businesses need to minimize tool sprawl and cost. Paying separately for chat, video calls, file sharing, and a phone system adds up fast. An all-in-one solution saves money and reduces the apps your team needs to learn.

Frequently Asked Questions

Is Teams Free good enough for a small business?
Teams Free offers unlimited chat, 60-minute group video calls, 5GB of storage per user, and basic integrations. For a business under 10 people with basic needs, yes. You upgrade when you need longer meetings, more storage, or recording.
Can a small business use Slack Free?
Slack Free limits you to 90 days of message history and 10 integrations. For a small business, losing message history is a real problem. Most small businesses outgrow Slack Free within 2-3 months and must decide between paying or switching to Teams.
Should a Google Workspace business use Teams?
No. If you use Google Workspace, Slack integrates much better with Google Drive, Google Calendar, and Gmail. Teams is built around Microsoft 365. Mixing ecosystems creates friction that slows everyone down.
