Why it matters
An invitation is a short-lived authorization to join a specific organization with a specific role. It must survive someone signing in with an existing account, and it must fail safely after revocation or expiry.
An invite is a temporary grant of future access. It needs a clear destination, an expiry and a rule for what happens if the recipient already has an account.
Decisions to make
- Set who may invite, which roles they may grant and when an invite expires.
- Decide what happens when the address already belongs to a member.
- Make resend and revoke visible to the administrator.
- Choose whether an invite reserves a paid seat before acceptance.
- Decide whether an existing user can accept with a different email address.
Build checklist
- Bind the token to one organization and one intended recipient.
- Consume an invitation once, atomically.
- Test expired, revoked, reused and wrong-account acceptance.
- Store an invite state and expiration separate from the membership it creates.
- Test repeated acceptance, revocation and a forwarded invite link.
Common mistakes
- Creating a membership simply because someone can read an email sent to a domain.
- Using a reusable invitation URL without an expiry.
- Automatically granting access based only on possession of a customer email domain.
