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.
