IMHO pricing per user / per month works well when clients are early and/or small startups, once the client has 50, 100, 200 employees then they must move out of these services because they get too expensive.

From the app from the article: 40$ per user / per month - 10 people startup => 5k a year - 100 people startup => 50k a year

When it becomes too expensive you only have a few options: - keep the heavy users in and remove other people from the service - have a shared user for people that don't use the service that often (If identity is important, who did what, then this becomes confusing) - move away from this solution, consider competitors

SaaS companies should consider medium to large companies and think about pricing caps, light agent roles, etc.

For example: the first 100 actions are free for each user, after that one simple fee is applied of 40 per month / per user. I don't know what is a proper solution yet.
