If I a guest is a member of another Workspace, do I need to pay for them in my Workspace?

If I add a guest to one board in my Standard Workspace, but they're a member of another Workspace, do I need to pay for them?

Hi Renata!

No. Users will become billable if they're Workspace Members or Multi-Board Guests (if they're members of multiple Boards under the same Workspace).

The doc "How billing Works with Trello Premium and Standard" describes this cases.
