Question on Mirroring

[Jonathan]

Would like to write information on one Trello card and have it mirrored and synced to another clients card so they don't see what isn't theirs. Also when they update their card, it mirrors to our main card . Is this possible or what do I need to do?

If you don't want clients to see other cards on your main board, then have the source card on the client board and then mirror that card to your main board. https://support.atlassian.com/trello/docs/mirroring-cards/
