Separate timing from exposure
Not every underbilling condition is a loss. Timing differences can be normal, but aging earned value without a clear path to billing deserves commercial review.
Trace performed work to the billing structure
Compare field progress and earned work with the schedule of values, approved contract value, pay application timing, and the rules governing when that work can be billed.
Find change-related revenue gaps
Performed change work may sit outside the billing stream because pricing, approval, documentation, or schedule-of-values integration has not caught up.
Review supportability
Revenue should have a defensible path through scope, evidence, entitlement, approval status, and billing mechanics. Unsupported optimism should not be treated like secured revenue.
Age the open position
The longer earned or claimed value remains unbilled, the more important ownership, documentation, follow-up, and escalation become.
