Is it possible to downgrade and upgrade account anytime?

I need to downgrade my subscription to the free plan, since we only need it seasonally. Will I still be able to access the form I created, and the submissions we've received? Eventually (prior to the Fall soccer season), I'd like to upgrade again, and hopefully use the same form, or an updated duplicate. Is this possible?

Yes, you may cancel and upgrade your account any time you would like. Before the next billing date cancel your subscription in order to avoid any further billing on the active subscription.

Downgrading the account would limit the account to a starter plan so the following limits would be applied to your account:

• 100 Monthly Submissions
• SSL Secure Submissions
• Receive 10 Payments
• 100 MB Available Space
• 5 Forms
• 1,000 Monthly Form Views
• 500 Total Submission Storage
• Unlimited Reports and Fields

If your account exceeds the below limit then your Forms may get disabled.

Let us know if you have further questions.

Thanks.
