A stakeholder wants to know what is actually driving churn and which signals show up early enough to act on. In this practical SQL walkthrough, I compare support tickets, product usage, and recorded churn reasons before churn, then segment the results by plan tier to show that Basic, Pro, and Enterprise follow different churn patterns.

Two dashboards disagree on revenue. Here is the exact SQL process I use to isolate definition and timeline mismatches.
