Cancelling Slack isn't quite as straightforward as most SaaS tools. Only workspace owners can change billing, the free tier has real limitations you should understand first, and there's a difference between downgrading to free and deleting the workspace outright. This guide covers both.
Before you cancel: export your data
Free Slack only keeps 90 days of message history. Everything older gets permanently deleted on a rolling basis. If your workspace has years of conversations you might need, export them first.
- Go to Settings & administration > Workspace settings
- Click Import/Export Data
- Select Export and choose your date range
- Slack will email you a download link when the export is ready
This exports public channel messages. Private channels and DMs require a Corporate Export (paid plans only, with admin approval).
How to downgrade to the free plan
This is the right option if your team still uses Slack but doesn't need paid features. Your workspace stays intact.
- Only Workspace Owners can do this. Check your role under Settings & administration > Manage members
- Go to slack.com/admin/billing (or click your workspace name > Settings & administration > Billing)
- Click Change Plan
- Select Free
- Confirm the downgrade
The change takes effect at the end of your current billing period. You keep using paid features until then.
How to delete a workspace entirely
If nobody needs the workspace anymore and you want it gone:
- Go to slack.com/admin/settings
- Scroll to the bottom and click Delete Workspace
- Confirm by typing the workspace name
- Click Yes, permanently delete this workspace
This is irreversible. All messages, files, channels, and member data are permanently deleted.
What you lose on the free plan
The free tier keeps your workspace, channels, and member list intact. But you lose: message history beyond 90 days (permanently deleted on a rolling basis), file storage beyond 90 days, unlimited app integrations (capped at 10), group huddles (limited to 1-on-1 only), screen sharing in huddles, guest accounts, Workflow Builder, and advanced AI features. Personal 1-on-1 huddles still work.
The 90-day message limit is the big one. Slack used to keep all messages on free workspaces indefinitely (just hidden behind a paywall). Since August 2024, they permanently delete messages and files older than one year on free workspaces, and the visible window is 90 days. Once they're gone, they're gone.
Current pricing (USD)
Slack bills in USD. Prices shown are per user per month.
| Plan | Monthly | Annual |
|---|---|---|
| Free | $0 | $0 |
| Pro | $8.75/user | $7.25/user |
| Business+ | $18/user | $15/user |
| Enterprise Grid | Custom | Custom |
For a 10-person team on Pro (annual), that's $870 USD/year (~$1,390 AUD). It adds up quickly, especially when Salesforce (Slack's parent company) has been steadily raising prices since the acquisition.
Slack bills for every member in your workspace, including inactive accounts. If someone joined your Slack six months ago and never came back, you're still paying for their seat. Before downgrading, remove inactive members under Settings & administration > Manage members to avoid overpaying on your final billing cycle.
Is the free plan enough?
For small teams (under 10 people) who mostly chat in real time and don't rely on searching old messages, the free plan works fine. You get unlimited channels, 1-on-1 huddles, and 10 app integrations.
You'll miss Pro if your team regularly searches for old conversations, relies on integrations with more than 10 tools, needs guest accounts for clients or contractors, or runs group video calls through Slack.
Alternatives
- Microsoft Teams (free tier) offers 60-minute group meetings, unlimited chat history, and integrates with Office apps. The strongest option for teams already using Microsoft 365.
- Discord (free) works well for small teams and communities. Unlimited message history, voice channels, and no per-user pricing. Less polished for business use, but functional.
- Google Chat (free with a Google account) is basic but covers messaging and integrates with Google Workspace. Best for teams already in the Google ecosystem.
Slack's $8.75 per user per month doesn't look like much until you count the seats. What other per-user charges are hiding in your statements?
Most people find 3-5 subscriptions they forgot about when they actually look. Upload a bank statement to Subtracker and see every recurring charge in 2 minutes. No bank login. No manual entry. $12.99 once.
