Root Operational Bottleneck
Delinquent balances are analyzed in an aging workbook refreshed from an AR export, so a write-off can be recommended from a tab that missed later cash applications.
Control Hazard & Audit Exposure
Write-off recommendations use an aging tab that missed last week's cash applications, and a collected invoice is still proposed for reserve.

Live Aging Analyzer that Blocks Write-Offs Until Cash Applications Are Current
Live aging analyzer that recomputes delinquent balances from current AR and cash applications and blocks a write-off while the aging is stale.
Continuous Assertion Rule
Aging assertion: a write-off cannot proceed unless the aging balance equals open AR minus cash applications posted through the recommendation date.
