Your client fills in a form. Trello gets the card.

No. They open the form from a link and fill it in, and their page opens from a link too. There’s nothing to sign up for and no password to remember. They’re never added to your board, so they don’t count towards a free workspace’s 10 collaborators.

The person who published the form. The card is made with their Trello connection, so Trello’s activity shows their name. The same goes for comments: the client’s messages are posted by a team member, which is why every one of them starts with “From client” and the client’s email address.

That can happen if the list was archived, the person who published the form left the board, or their Trello access was revoked. The visitor is told the form is temporarily unavailable, and the answer is recorded as failed so it doesn’t go missing. In your list of forms, that form shows a warning with a Reconnect button. One click connects it again.

Yes. Every card has a Client section on its back. Click Share, type the client’s email, and they get a link to their page with that card on it. The same section shows who can see the card, when they last opened it, and the stage they see. Stop sharing takes it off their page.

Yes. On the card, write what you’d like approved and choose Ask to approve…. Pick which of the card’s files they may open, and the list the card moves to if they approve or ask for changes. They get an email, see the pictures on their page, and press Approve or Request changes, which needs a few words on what should change and can carry files. The card moves on its own, a comment records the answer, and its front shows Awaiting, Approved or Changes. If nobody answers, they get one reminder after three working days.

No. They see the card’s title, the stage you gave its list, their own answers, the messages you send them from the card’s Client section, and the files you pick for an approval. The description, checklists, your team’s comments and every other file stay on the board. This is checked on the server for every request the page makes.

When a request comes in or is shared with them, when it moves to a list with a different stage (at most one email an hour per request, with the stage it has by then), when you write to them, and when you ask them to approve something, with one reminder if they haven’t answered after three working days. Several messages within five minutes go out as one email. Moves into a hidden list send nothing. You can switch stage emails off for the whole workspace, and each client can switch off their own emails with one click.

One subscription covers the whole Trello workspace, with every board, every member and as many forms and answers as you need. It’s €10 a month or €100 a year. The 5-day trial starts when you publish your first form, not when you install the power-up, and it doesn’t ask for a card.

New answers stop. The form link still opens, but it tells the visitor the form isn’t accepting responses right now. It says nothing about payment, because your client sees that page, not you. The client page closes the same way and no emails go out. Your forms, their settings, every card and every past answer stay exactly where they are. Subscribe and it all works again.
