Why does revenue leakage fail?

Table 5Why does revenue leakage fail?

Failure mode	Boundary lost	First diagnostic
Denominator drift	Eligible lines change between expected, invoiced, and collected views	Reconcile the line key and inclusion rule.
Timing collapse	Not-yet-due and overdue amounts become one shortfall	Declare the service period and collection cutoff.
Reason-code inflation	A provisional label becomes a confirmed loss	Require evidence, owner, status, and disposition.
Credit confusion	Approved concessions are treated as billing failure	Check authorization against the expected-value boundary.
Pipeline-style aggregation	A total hides the transition that failed	Separate promise, entitlement, invoice, and cash states.

Pricing & revenue architecture

What is revenue leakage? The gap between promised and collected revenue
