How to Cancel Slack - Step by Step Guide

How to Cancel Your Slack Subscription

A straightforward guide to downgrading Slack to the free plan - who can do it, what happens to your messages, and what credit you can expect.

Before You Cancel Slack

Three things to sort out before you start the downgrade process.

  1. Confirm you are the workspace owner. Only workspace owners can access billing. Admins cannot. If you are an admin trying to cancel on behalf of your company, find out who the owner is first - otherwise you will hit a dead end in the settings.
  2. Understand the message history cut-off. On the free plan, only the last 90 days of messages are visible. If your team relies on older conversations for reference or compliance, export your message history through Slack's export tool (Settings and administration - Workspace settings - Import/Export) before downgrading.
  3. Check how many apps and integrations you use. The free plan supports up to 10 app integrations. If your workspace uses more, some will stop functioning after the downgrade. Make a list and decide which ones to keep.

How to Cancel Slack - Step by Step

These steps apply to Slack Pro, Business+, and Enterprise Grid plans. The cancellation must be done via the web interface at slack.com - you cannot change billing from the desktop or mobile app.

  1. 1
    Sign in at slack.com as the workspace owner

    Go to slack.com and sign in with your workspace owner credentials. Only owners have access to billing settings.

  2. 2
    Click your workspace name in the top-left

    Once inside your workspace, click the workspace name at the top of the left sidebar. This opens the main workspace menu.

  3. 3
    Go to Tools and settings, then Billing

    From the menu, select "Tools and settings," then click "Billing." This takes you to your current plan, seat count, payment method, and billing history.

  4. 4
    Click Change plan

    On the Billing page, click the "Change plan" button. Slack will display the available plan tiers.

  5. 5
    Select Downgrade to Free

    Choose the Free plan. Slack will show you a clear summary of features you will lose, including message history limits and the app integration cap. Review this list, then proceed.

  6. 6
    Confirm the downgrade

    Confirm your choice. The downgrade takes effect at the end of your current billing period (for annual plans) or immediately for monthly plans with a prorated credit applied. You will receive a confirmation email from Slack.

What About Your Other Subscriptions?

Cancelling Slack is a good moment to review your full SaaS stack. Most teams discover 2-4 subscriptions they had forgotten about once they do a proper audit. CostLoop is a free subscription tracker that gives you one dashboard for every tool you pay for - renewal dates, costs, owners, and cancellation links all in one place. Free plan tracks up to 5 subscriptions, no credit card required.

Frequently Asked Questions

Can I cancel Slack mid-month?

Yes. You can downgrade to the free plan at any time, even in the middle of a billing period. Slack calculates the unused portion of your paid period and issues it as a prorated account credit. This credit is applied automatically if you upgrade again - it is not issued as a cash refund.

What happens to message history on the Slack free plan?

On the free plan, only the most recent 90 days of messages are visible. Older messages are not permanently deleted - they remain stored by Slack but are hidden from view. If you upgrade again in the future, your full message history becomes accessible. If you need older records now, export them before downgrading.

Who can cancel a Slack subscription?

Only workspace owners can cancel or downgrade a Slack plan. Workspace admins do not have access to the billing section. If you are an admin who needs to cancel, identify the workspace owner and ask them to complete the process, or request that Slack support transfer ownership first.

Do I get a cash refund when I cancel Slack?

No. Slack does not issue cash refunds when you downgrade. The remaining unused days on your plan are calculated and converted into a prorated account credit. This credit is applied automatically on any future Slack purchase. If you are not planning to use Slack again, that credit will go unused.

Keep Track of Every Subscription You Still Pay For

After cancelling Slack, make sure you know exactly what else is renewing and when. CostLoop shows you all your subscriptions, their costs, and upcoming renewal dates in one simple dashboard.
