Will our forms be affected if we upgrade the account?

I have 1 more question. If for some reason at the trade show we go over our limit of views and responses in the free version, can I upgrade without any disruption to our form, the link, or the usage?

Your forms, submissions and data will not be affected when upgrading the account. We will only increase usage limits for you. 

Here is a guide, which would be of help: Understanding-Your-Account-Usage-and-Limits.

If you have any other questions, please let us know.

Thank you!
