Frequently Asked Questions

01 How much does Slack cost per user?

Slack Pro costs $7.25/user/month (annual) or $8.75/user/month (monthly). Business+ costs $12.50/user/month (annual) or $15/user/month (monthly). Enterprise Grid has custom pricing based on organization size.

02 Is Slack free?

Slack has a free plan, but it's limited to 90 days of message history, 10 app integrations, and 1:1 video calls only. After 90 days, older messages are hidden (not deleted, but inaccessible). For most teams, the Pro plan is needed.

03 What happens to old messages on Slack free?

On Slack's free plan, messages older than 90 days become inaccessible. They're not permanently deleted - upgrading to a paid plan restores access. But while on the free plan, you can't search or view messages beyond the 90-day window.

04 Is Slack cheaper than Microsoft Teams?

It depends. Microsoft Teams is free for personal use and included with Microsoft 365 business plans ($6-$22/user/month). Standalone, Slack Pro at $7.25/user/month is cheaper than Teams Essentials at $4/user/month. But if you already have Microsoft 365, Teams is essentially free.

05 Does Slack charge for guests?

Slack Connect guests (external collaborators) are free on all plans. But single-channel guests on Pro plans cost $0/user - they're free. On Business+ and Enterprise, single-channel guests require paid seats.
