If your organization is subscribed to a paid version of Uizard, you will have the option to cancel your subscription.
To do so, go to 'Organization Settings' > 'Billing.'
At the bottom of the page, you will see a dialog box for 'Cancel subscription.'
Click on 'Cancel subscription.'
Your organization subscription will then be canceled. This means that the organization will be downgraded to the free plan. You will also get a refund for the portion of the current subscription that you haven't used.
Note that doing this might lead to members losing access to certain features.
