# Subscription event distribution

*Publishing · Ownership Gap · Risk Transfer*

## Pain

A media company's subscription platform generated lifecycle events (new subscriptions, renewals, cancellations, payment failures) that needed to reach six systems: CMS for access control, CRM for the customer view, finance for revenue recognition, email for triggered communications, analytics for churn modeling, and print fulfillment for physical subscribers. Each system expected a different format and had different timing requirements. The integration had been built ad hoc over years. Nobody knew who owned it.

## What we built

A fan-out pipeline that consumes subscription events in real time, transforms each event into the format the destination expects, and delivers it with exactly-once guarantees. Every event is logged in a unified event stream accessible through the seamless dashboard.

```

## What we own

Delivery monitoring across all six destinations. Alerting when any system falls behind. API change monitoring for every target. We guarantee exactly-once delivery, which matters most for finance where duplicate records cause reconciliation headaches.

When the email platform migrated to a new API version, we absorbed the change. Subscription communications kept flowing.

## Business outcome

A recurring class of support tickets disappeared: CMS access not updating after payment. Finance reconciliation went from a weekly manual process to continuous. Subscription data is now consistent across all six systems within seconds.
