Upgrading
If you are on the Basic plan and want to upgrade to a paid account, click on your account icon in the upper-right corner of your dashboard. Select Plan Info, and then click Manage Subscription.
Switching my subscription from a Monthly to Annual subscription
Monthly plan users can switch to an Annual plan and save on their payment plan. See our pricing plans here.
If you are already an Annual user, you will need to cancel your subscription and wait until the subscription is up before you can switch to a monthly plan.
Note: If you are on an old plan that is no longer being offered, please contact our support team who will help upgrade you to the latest plan.
