Trello: Stop Tidying the Board Every Monday. One Free Automation Rule Marks Cards Complete When They Land in Done

Description and use

Automatically marking cards complete when moved to Done in Trello removes manual status updates and keeps the board tidy.

Problem

Team members drag finished cards to Done but forget to tick them complete, causing overdue due dates and a cluttered board that requires daily tidying.

Outcome

The automation rule eliminates the need for manual completion ticks, keeps due dates accurate, and removes the weekly board tidying task.

Workflow

• Create a board named "Client onboarding" and add lists To do, In progress, Waiting on client, Done.
• Add one card per onboarding task under To do, prefixed with the client name.
• Create a label "Urgent" and apply it to relevant cards.
• Set a due date on each card; due dates turn green when the card is marked complete.
• Open Automation panel, create a rule: trigger "Card Move" to list "Done" by anyone, action "Mark card as complete".
• Save the rule and test by moving a practice card to Done to confirm it ticks complete automatically.

Evidence

When those tasks live in email threads and a shared spreadsheet, a client can wait a week for an engagement letter because nobody knew it was theirs, and the Monday meeting becomes a round of "where are we with…?"

People drag finished cards to Done and forget to tick them complete. The due dates keep showing as overdue, the board looks worse than the work really is, and someone spends ten minutes every Monday tidying it.
