The Opportunity

A Shopify app that alerts merchants when subscription cancellations or pauses are triggered by customer account changes, such as payment method removal. It helps subscription stores catch silent churn-causing bugs before revenue is lost.

"A Shopify subscription bug can silently cancel recurring subscriptions when customers remove a card from Shop Pay, causing merchants to lose recurring revenue without obvious warning."

Implementation Notes

Listen to Shopify subscription and customer/payment-related webhooks, correlate cancellation events with Shop Pay or payment method updates, build an incident timeline per subscription, and surface actionable alerts plus exportable reports; include filters by plan, customer segment, and cancellation reason to help merchants quantify impact.
