Tenant & Member Subscriptions / Multi-Tenant Single DB

Thought I'd ask for any thoughts on anyone with similar experience... I've created a multi-tenant app and looking into a payment processing... either straight Stripe, Cashier or Spark package, etc. that may be able to handle the requirements.

Requirements I need:

Tenants sign-up to the app and be billed monthly or yearly subscriptions for app usage

Each Tenant will have members who will register and pay for member fees either monthly/yearly subscriptions

A Tenant could invoice a member separately for additional services they offer

Tenants set the subscription amounts for their plans

Spark looks awesome.. but looks like you can only have Subscriptions for one model. I'd need subscriptions for Tenant model and User model. With the amount of functionality.. sounds like I may need Stripe flexibility..

Thanks!
