App usage events that never reach rating
Customer apps can record sessions that mediation never sees. Tracing that gap belongs in billing validation when app analytics feed the rating path.
Prepaid and digital lifestyle products often meter usage inside a customer app before the network rating path sees an event. When product teams celebrate engagement metrics that finance cannot invoice, the gap is usually between the analytics pipeline and mediation.
A narrow but useful check
We sample sessions marked complete in the app analytics extract and ask whether a corresponding usage event appears in mediation within the agreed latency window. Missing events are listed by handset OS, app version, and network type — not as a vague “funnel issue.”
Why finance cares
Unrated completed sessions are lost revenue. Double-counted sessions are customer trust problems. Either way, the finding needs to be specific enough for engineering to patch and for finance to estimate exposure for the cycle.
This check sits inside our broader app analytics work for billing validation engagements when the product under review is app-metered.
