One submission is one count?

Q1：1申請＝1件というカウントで間違いないですか

Hi support_support817,

I just wanted to remind you that I'll be helping you in English using Google Translate because our Japanese Support agents are busy helping other Jotform users right now, and you can reply in whichever language you feel comfortable using. But, if you'd rather have support in Japanese, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, to clarify, are you referring to the submission count? If so, when clients or customers fills out your form and successfully submits it. It is one count on your submission. Here is a guide on Understanding Your Account Usage and Limits.

Let us know if there’s anything else we can help you with.
