Root Operational Bottleneck
SaaS usage measures for true-ups are compiled in a metrics workbook from exports that do not share a key with product telemetry, so the invoice is paid from the sheet total.
Control Hazard & Audit Exposure
True-up invoices are paid from a usage sheet that does not match product telemetry, so contracted units and billable activity disagree.

Usage Telemetry Feed that Asserts True-Up Quantities Against Product Activity Measures
Usage telemetry feed that computes activity-based measures from product events and asserts the true-up quantity before the invoice can be paid.
Continuous Assertion Rule
True-up assertion: a usage true-up cannot pay unless the invoiced quantity equals the activity measure from product telemetry for the same period and SKU.
