Can anyone out there explain how Trello Licenses Work?

[Mario Columbia]

Can we mix and match Trello Licenses, or do we need everyone licensed as experts?  

[Dreamsuite Mike]

No mix and match of license levels.

If you have a Premium workspace, every workspace member will be chargeable

Trello has:

• Workspace Members (Charged as per Trello pricing)
• Multi-board workspace guests, these are not workspace members and have no visibility of the workspace boards other than the boards they are members of.  These are charged at the same rate as a Workspace Member
• Single-board guests.  These members only belong to 1 board and are free (this is something you can make use of to keep costs down)

Thanks @Dreamsuite Mike I was able to use this info to rehabilitate my frozen school parents Trello. While I'm a fan of Atlasisan's general approach to licensing The ingestion of Trello and the changes to the licence regime obscured the benefits for me for some time. It has corroded my expectations.

So to those reading this after me. yes it can be done, you can have one user paid and many guests. Now you just need to decide how to manage security and governance.

Review The Pricing Plans 

Step 1 clean out your multi board guests, those days are over. you can do this by using the MEMBERS view in the Board or Workspace nav bar on the left.

Step 2 decide what you need to do with 2FA, bearing in mind some users will very likely have other Atlassian product accounts from work or other orgs.

Step 3 find a way that fits into the culture of your people to spread the licensing costs. I'm going with user pays, ie more boards more contribution.

Step 4 IF you run into limits, ask for help.
IF your an NFP this may help.
