Support ticket volume spike
Horizon: 21 days before churn. 2x+ increase in support ticket volume over a 14-day window. Can indicate acute operational failure, team onboarding friction, or build-up before a renewal-time ultimatum.
How to detect it
Ticket count per account per 14-day window. Compare to the rolling 90-day baseline. Threshold: ≥2x baseline AND ≥3 tickets in the window (to filter noise).
Recommended intervention playbook
Response SLA: CSM contact within 48 hours of signal fire. Do not rely solely on support team routing — CS ownership is stronger at renewal. Review the tickets in aggregate: is there a root cause fix possible? Is the customer contemplating a switch and stress-testing?
