Thoughts, 2025-07-07

 account system
  * data model
  * user interface
  * admin interface
invites and registration
  * is this a different thing from the account system, or a feature of it?
payments and billing
  * evaluate service provider (Helcim, Stripe)
  * prototype integration with account system


==== account model ====
=== level 1 ===

primary account
  * pays for things, 1:1 with a subscription
  * one inbox

=== level 2 ===

primary account
  * aliases
  * bring your own domain

=== level 3 ===

secondary accounts / multiple inboxes
  * is there a difference between an extra mailbox and a secondary account?
  * primary account pays
    * subscription tiers? (1, 2, 10 mailboxes, etc.) (Fastmail "family plans")
    * pay per user? (Fastmail "business plans")
    * can secondary accounts have their own billing info?
  * what admin controls does the primary account have?
    * edit aliases
    * grant secondary accounts ability to create their own aliases (Fastmail does this)
      * on service domains (crowmail.ca, crowmail.net)
      * on primary account custom domains
  * can a secondary account be "upgraded"/moved to it's own primary account?
    * who can initiate?
Fastmail has the concept of a Team
  * single accounts are still a part of their own Team
  * a Team is what gets billed
  * a Team has one or more Admins
    * Admins can edit billing info, add/remove users, etc.
