B2C Subscription Model - Leads tied to each other

[Anonymous]

Hey peeps! Could use some help on a question I have. We're a B2C Subscription SaaS modeled business selling software for students.
- Free users
- Paying subscribers
- Parent accounts
- Student accounts

Parents can buy this for their students under a parent subscription or a student subscription. Bob, parent, might buy it for Johnny, student. We're trying to put all of our leads into Marketo and get the campaigns going to email free users to convert them to paying users. Bob's account could be a free account, but he could be paying for Johnny's student account, so we want to have parent and student accounts linked so we're not emailing Bob to upgrade if he's already paying for Johnny's account.

Any solutions to link accounts? If we insert the same user ID for parent and student would that do it? Any ideas would be appreciated. Thank you! - Zaki

Is there a field on the Student Account that indicates if a Parent is paying?

Student=Johnny
Related Parent = Jack Sr

If Related Parent IS NOT EMPTY, then do not send.
