What is the benefits of having a Corporate account than Personal Account?

Hi,

If you mean to say the "paid account" over the free one,  the benefits can be seen on the pricing page. http://www.jotform.com/pricing

Basically, all types of accounts, free or paid has all access to Jotform features. The only difference between them is the submissions limit, (Regular, SSL and Payment Submissions) as well as the upload space capacity.

Let us know if you want more clarifications or if you mean something else.
