Can to replace a user so avoid getting double billed

[Arfah Khan]

Hi, I'm just setting trello up and have added a few users but I now want to replace them with others.  Is there a way I can replace them so I don't get billed for the old users + new ones? So far, I've removed the ones I no longer require on trello and have sent invites to new users.  Essentially, I want to be able to switch the 'per user' trello licence from one user to another.

Hey @Arfah Khan! You won't be billed for these replacements if you're only replacing the billable users in your Workspace instead of adding new ones. For example, let's say you have a Premium Workspace with 5 billable users, including you. Then, 2 out of the 5 users left your team or organization, leaving you with 3 billable users and 2 licenses available to be reused. Then, 2 new users join your team or organization, and you invite them to your Workspace. In this situation, you won't be billed for these two new users who joined because you're simply reassigning the licenses you have available from the other 2 users who left.
