What happens to a deal when it falls through — does it disappear from the pipeline?

It disappears from the columns, not from Doxario. The card menu has a single entry for this, “End deal …”, which opens the question “How did this deal end?” with four answers:

• Sold — the purchase has been completed.
• Failed — buyer or seller walked away; the purchase will not happen.
• Another buyer got it — the property goes to another buyer.
• Archived, no outcome — neither success nor failure, for example a test, a duplicate or a dormant case.

All four take the card off the active board, because the board is a working list and a closed case distracts from the live ones. If closing-critical mandatory tasks are still open, closing is not blocked — the notice lists them, and the decision is recorded under your name.

To bring the case back, use the “Ended” view. Closed cases sit there with “Result” and “Year” filters and a search; the row menu offers “Restore”.

The stage is preserved. That is why “Failed” is not a stage of its own: for analysis, what matters is precisely which stage a case failed at — in negotiation, or only at the notary. As a stage of its own, that information would be destroyed.

A closed case also stops counting towards the weekly review.
