Once you have an active subscription, you can manage it from Admin Panel > Plans & Billing. The billing page shows your plan, next payment date, and current seat usage.

​
Managing Seats

Every active user in your workspace counts as a seat, including Slack bot accounts. You can adjust your seat count at any time.
1

Open seat management

Click Update Seats on the billing page.
2

Set the new count

Enter your desired number of seats. You cannot go below the number of seats currently in use (active users + pending invitations).
Need to reduce seats below current usage? Remove users first, then adjust the seat count.
3

Review the billing impact

  • Adding seats — you’ll be billed a pro-rated amount immediately.
  • Removing seats — the change takes effect at the end of your current billing cycle.
4

Confirm

Click Confirm Change to apply.

​
Stripe Customer Portal

Click Manage Plan on the billing page to open the Stripe customer portal. From there you can:
  • Update your payment method
  • View and download invoices
  • Cancel or modify your subscription
