Is it possible to pay for JotForm for a shorter period than 1 year?

My form will be obsolete by April.

Yes, it is possible. We also have an available monthly subscription to our paid plans.

You can check that from the billing section of your accounts page https://www.jotform.com/myaccount/billing — OR our pricing page — https://www.jotform.com/pricing

Since you are planning to terminate the subscription come April, I would like to inform you that you can cancel your subscription at any time. Just know that the subscriptions are automatically renewed until it is canceled.

If you have other questions or concerns, please feel free to contact us again anytime.
