Free Vs. Paid User Roles

Hi there,

I am a Gravity Form user unsure if this plugin is what I need. I will be using Gravity Forms Limit Submissions to set up separate Limit Submission feeds for paid and free users. In these feeds I will set the submission limit (credit limit) and set the Time Period to “Per month”.

Under Rules, I will have it be based on Each user. My question is, where and how can I determine whether the user is a free or paid user? Should I create a new user role with your plugin and then select the role in Gravity Forms Registration add on?

I do have user registration add on and gravity wiz perks.

What is the best way to achieve this? Should I be creating new roles in WordPress?
