Churn survey questions
A departing customer has nothing left to sell you — which is precisely what makes their testimony reliable. It still has to be collected properly: the cancellation survey must be short (the respondent is already at the door), focused on THE main reason for leaving rather than a list of grievances ticked out of politeness, and curious about the destination: what are they switching to, and what would have kept them?
The generated outline fits in five to ten questions: cancellation confirmation (screening), main reason as single choice — forcing one pick reveals the true hierarchy —, replacement solution, the moment the decision tipped, and two open questions: what would have changed the decision, and a free message. Every exit verbatim is worth ten answers from happy customers.
