hey @tee746 - thanks for asking for clarifications around pricing! Happy to provide some - please do keep asking if its still not clear
Each option has benefits/drawbacks depending on what your situation is, but here is some general guidance:
Business plan teams receive unlimited active identity users, and this applies to all sites in the team, but those plans do cost $99 per member of the team. If you have many members in your team, but only a single site you want identity on, it may be a better deal to have the starter plan (at $15/member) and the $99 site add-on.
Only having business with 1 member does limit so many of the really amazing collaborative features that Netlify offers, though, and that’s a big drawback - If you are expecting to have over 5000 active identity users, we should talk about getting you connected to someone here to see if we can create a more custom solution that meets your needs better.
Is this helpful? Any other questions?
