How to monetize the mailwizz plans.


I see that Mailwizz provide feature to create plans and then assign the plans to a customer group and they can purchase it after login to their account. But I want to do it this way :

1. Give a link to all my plans on my website (A link from my website to a Mailwizz page listing all plans).
2. Once some one selects and purchase a plan, his account is created in the mailwizz and he gets activation link etc.
3. Once his payment is successful, he gets the invoice and immediately start to use his account.

Can someone guide me on how to set this up.
