In PLG, you want to make sure it is easy enough to start, so it should be usually per-user pricing because if I am a team of 10 people and I am buying InVision or Slack for 10 people.
Ideally, I should start for free and then I should be able to add on users, so the real power unlocks when the entire company uses it.
PLG in an HR or a collaboration world has a lot more land and expand potential like for example Freshdesk or Freshsales because it can only expand within one function.
The annual contract value should be designed around the buyer.
