Like a virtual office, a workspace is where work happens in Slack. All your channels, direct messages and tools live in a workspace.

Customisable sections

Keep your projects, teams and priorities straight, by organising your channels and conversations into custom, collapsible sections in your sidebar.

Slack huddles

Take a break from typing and start a live voice conversation in a channel or direct message. Brainstorm, make decisions or just catch up – all at the flip of a switch.

Frequently asked questions

You can use your credit card to pay for any subscription. If you sign up for an annual subscription and plan to spend at least $US5,000, we can invoice you annually. Visit the Help Centre for more information or Contact us to start the process.

Every day we check to see if everyone on your team is active. If they have been inactive for a period of time, we stop charging you for that person and add pro-rata credit to your account for the time you’ve already paid. You’ll always and only be charged for what you use – fair and square!

Once your team take out a subscription, we’ll redeem your credit balance until it runs out. We won’t start charging your subscription to your credit card until then. As long as you sign up for a subscription before the expiry date, that credit is yours to use until it’s all gone.

We’ll apply a one-off, pro-rata charge to your credit card to cover your new team member’s account for the remainder of the current billing period.

As an example, suppose your team is on the ‘Pro subscription’, which costs $US8 per active user per month when billed monthly. You add a new team member ten days into your billing period, and there are 20 remaining days in the month. The per-day cost for each user is $US8 / 30, so we will make a one-time charge of $US5.33 ($US8 / 30 days * 20 days) to your team’s credit card on file.

Team owners can change the team’s subscription level. There are two options when downgrading from a paid subscription to the Free subscription:

  • You can downgrade to the Free subscription immediately. If there is more than one day until your renewal date, we will adjust the remaining balance on your account pro-rata and hold it for your team as a credit. You can use that credit towards any reactivation of your paid subscription in the future.
  • We can automatically downgrade you to the Free subscription at your next renewal date. Your subscription will remain active at its current level until the end of the billing period that you’ve already paid for.

We do not offer refunds.
