Hi @Dharmesh_Vyas ,

Welcome to the community!

Basically whatever plan anybody is using will get that much benefit only!

Like if Trello business account holder joins Trello free account holder's team Trello business account holder will enjoy business benefits and Trello free account holder will get free benefits only!

It doesn't matter who joins whos' team benefits are fully depend on what plan they have purchased!

@Dharmesh_Vyas If you create a Business Class team, then you can add members to your team and you will have to pay for them.

However, you can also simply invite free Trello users to boards that belong to a Business Class team, and in that case they are called "single board guests". They will not be billable, but they will have access to all the business class features (ie. unlimited power ups, large file size).

If you invite the same free Trello account to more than one board that belongs to the same business class team, then that free user becomes a "multi-board guest" of your team, and you will be billed for them.
