Only workspace admins can change the plan.
Change your plan
Go to Billing > Subscription.
Under Change your plan, set the Number of users you need. Your plan follows the seat count.
Click Update plan.
If your plans are set up for you by your head office, use Manage your subscription on the same page instead and pick a plan from the list.
When it takes effect
Upgrades are charged a prorated amount straight away. Downgrades take effect at the end of your current billing period, and you keep your current plan until then.
Moving to a smaller plan
A Before you downgrade step asks What is the main reason for this change? Pick one: Too complicated, or I don't know how to use it; Price; Not using the features; Office closing or changing hands; or Other. Confirm downgrade turns on once you've picked one.
After you confirm, a Plan change scheduled banner shows the date your workspace moves, and your current plan shows Active until that date.
Changed your mind?
Before that date, click Cancel update on the banner, then Yes, keep my current plan. Or pick a different plan.
Your payment method
The Payment method card at the top of Billing > Subscription shows which card or account your subscription is charged to. Use Update payment method to change it.
