How can we stop auto billing and payment for next year?

As far as I checked, you have a Bronze plan currently. If you want to downgrade your account to the Free plan, please follow these steps:

1. Make sure you are logged in using your JotForm account/username at https://www.jotform.com/login 

2. First, click the human icon shape at the top right corner and click the "Account" text link. 

3. Go to your Account->Billing page or click on this link https://www.jotform.com/myaccount/billing.

From your Current Plan you can switch to Starter/FREE plan by clicking on the Downgrade button. 

4. A pop-up window will provide additional information about the downgrade, follow the instructions mentioned to proceed on cancelling your plan or switching back to "Free" account.

 Please do take note of the following:

1. After confirming the subscription cancellation, the subscription will no longer be billed on the Next Billing Date.

2. Although there will be no further billing charges after the subscription cancellation, the account will still remain on paid status (Bronze, Silver, Gold) for the period you paid for.

3. The subscription will automatically downgrade to the Starter/FREE plan on the date of its subscription expiration. 

Please try and if you need further assistance, let us know.
