Leakage is an architecture problem, not an audit finding
Revenue slips at the boundaries, between mediation, rating, charging, and the ledger: records mediated but never rated, plans that do not match the catalogue, services live but never billed.
Found in a quarterly audit, the money is already gone. The shift buyers ask about is from after-the-fact audit to continuous, event-level assurance.
Reconcile usage to revenue as it happens
The measure is revenue leakage: billable revenue earned but not invoiced, as a share of the total, tracked continuously rather than sampled once a quarter.
This maps to the assurance domain of the TM Forum process framework, where billing means accurate charging and reconciliation, not just generating an invoice.
Where the ERP closes the loop
When the billing stack and finance share one platform, the usage-to-ledger loop closes and a mismatch surfaces before it compounds. On Hudace, Xenon AI scans charging and usage streams for the patterns an analyst would miss, a rating mismatch, an abnormal top-up, and flags them for review.
The same connected data drives churn and ARPU, so a retention offer reflects real margin, not just discount depth.
The numbers to watch
Track leakage continuously, and watch it alongside the retention numbers it feeds.
Revenue leakage %
Billable revenue earned but not invoiced / total billable revenue. Tracked live, not in quarterly audits.
Churn rate
Subscribers lost in period / subscribers at start. Billing-dispute churn is preventable.
ARPU
Average revenue per user = recurring revenue / average subscribers. Rising churn with flat ARPU is the alarm.
Straight-through billing
Share of usage rated and billed with no manual touch. Higher means fewer gaps to leak through.
