Cancel Slack yourself

TLDR: A Workspace Owner opens Manage billing and chooses Downgrade to Free. Paid features stop and the free limits apply, while the workspace stays and the fee is not refunded.

Downgrade to the free plan

You are a Workspace Owner, or the member who upgraded the workspace. This is the paid plan bought from Slack, including one paid by card, ACH, Apple Pay, or invoice.

  1. 01On a desktop, click Admin in the sidebar. If you do not see Admin, click the workspace name.
  2. 02Select Manage billing.
  3. 03On the Overview tab, select Change plan details.
  4. 04Select Downgrade to Free, and choose whether it starts now or on the next renewal date.
  5. 05Click Continue to Checkout.
  6. 06Review the downgrade, then click Downgrade Slack.

Apple Pay on the Slack checkout page is a way to pay Slack. It is not an App Store subscription, so there is no separate Apple cancellation.

How to know it worked

  • The change is finished when you click Downgrade Slack.
  • Open Manage billing again and check the overview. It should show the free plan, or the renewal date you chose for the switch.
  • If the paid plan is still set to renew, the downgrade did not finish.

Watch out for

  • Downgrading to free removes paid features. Message, file, and app limits then apply.
  • A member who does anything in Slack during a 28-day period counts as active, and Slack bills for active members. Someone you already paid for who goes inactive can leave a prorated credit.
  • Any plan can be paid by credit card. US workspaces can also pay by ACH. US and Canada workspaces can pay with Apple Pay, which Slack is rolling out gradually.
  • An annual workspace can pay by invoice, by check or direct deposit, if it has at least 3 active members and at least 58 members on Pro or 28 on Business+. Discounted plans, other than Slack for Education, need an invoice of at least $5,000 US Dollars. Invoice payments include a remittance fee.
  • On an annual plan, new members can leave a balance that Slack charges on the last day of the month.

Slack refunds

  • Moving from Business+ down to Pro can leave Slack credits for unused time on the paid plan.
  • Those credits have no currency or exchange value. They cannot be transferred, and they are non-refundable. They expire when the paid Slack plan ends.
  • The cancel steps for the free plan do not offer a cash refund.

No confirmation email? Then it didn't happen.

Our letter comes with a receipt. This is when it is worth having us do it.

Have us cancel Slack

  • You cannot log in, or do not remember the email

    The notice goes to Slack Technologies in your name and address. No login, no password.

  • The downgrade was saved for the next renewal, and another charge came through

    The notice states the date you wanted the paid plan to stop, with proof of when it was sent.

  • You were charged after cancelling

    The dated notice and proof of delivery are what your bank asks for when you dispute the charge.

  • You would rather not chase support

    We post and email the notice, then follow up with Slack until they confirm. If they never do, you get your money back.

Cancelling Slack

What people ask about Slack.

Who can cancel a paid Slack plan?

A Workspace Owner, or the member who upgraded the workspace. From a desktop, open Admin, then Manage billing, then Change plan details, and choose Downgrade to Free.

Does cancelling Slack delete the workspace?

Switching to the free plan keeps the workspace and applies the free limits on messages, files, and apps. You lose the paid features.

Can I get the unused time refunded?

A drop from Business+ to Pro can leave Slack credits for unused time. Slack says those credits have no cash value and are non-refundable. Downgrading to free does not describe a cash refund.

I pay Slack with Apple Pay. Do I cancel in the App Store?

No. Apple Pay is a checkout option on Slack's own billing page for workspaces in the United States or Canada. Cancel on that billing page with Downgrade to Free.

Can you cancel Slack without me logging in?

Yes. The notice goes to Slack in writing, so it does not depend on you reaching a cancel button inside your account. A lost password or a locked account does not stop it.

Does the letter ask them to delete my data?

Yes. It asks the company to erase the personal data it holds on you where it has no lawful reason to keep it, and to confirm in writing once it has.
