Best fit for
If you run any of these, ChurnStop is a good match out of the box:
- SaaS on WooCommerce- Price-sensitive SaaS customers cancel because their job-to-be-done shrank, not because they hate you. Moving them to a cheaper plan preserves the integration and the account, which a discount coupon does not.
- Membership sites- Member churn is driven by life events and attention budget, not price. Pause converts 2–3x better than discount for memberships because it matches how members actually think about their commitment.
- Replenishment commerce- Customers who subscribe to consumables cancel on timing, not intent. A skip-renewal offer converts 40%+ of "not using" cancellations. The product is fine. The cadence is wrong.
