Plugin description\
With this Add-on for Super Forms you can create forms where users will be redirected to the PayPal's checkout page. From "subscriptions with trial period checkouts" to "simple one product checkouts" it's all possible with this add-on for Super Forms.
This add-on is also compatible with:

Because of it's seamless integration with Super Forms your contact entries status will be updated after PayPal IPN has notified your website about a successfull payment. Along with this a new Transaction will be created so a record of payments will be kept within your WordPress back-end. Within the back-end you can also track current active/suspended/canceled subscriptions
