What problem does it solve? Subscription businesses lose revenue to both voluntary churn (customers choosing to cancel) and involuntary churn (failed payments), often without any structured retention process. This Skill provides a complete retention playbook covering cancel flow design, reason-matched save offers, churn prediction signals, and failed-payment recovery. ## Core Features & Use Cases - Cancel Flow Design: Builds the full trigger → exit survey → dynamic save offer → confirmation → post-cancel sequence, with offer-to-reason mapping (discount, pause, downgrade, feature unlock) and UI patterns that avoid dark patterns. - Involuntary Churn Recovery: Implements the dunning stack — pre-dunning card expiry alerts, smart retry schedules by decline type, a four-email dunning sequence, and grace period management for Stripe, Chargebee, Paddle, and Recurly. - Proactive Retention: Defines churn risk signals, a weighted 0-100 health score model, risk tiers, and intervention triggers before customers reach the cancel button. - Use Case: A SaaS product with 7% monthly churn asks for a retention strategy; the Skill designs the cancel flow with exit survey categories, maps save offers per reason, sets up dunning for failed payments, and delivers a phased implementation checklist. ## Quick Start Ask the agent to design a cancel flow and dunning strategy for your subscription product, providing your churn rate, billing provider, and plan structure.
