Root Operational Bottleneck
Capitalizable purchases are copied from AP invoices into an asset addition sheet, then depreciated in separate tax and GAAP tabs that nobody reconciles to disposals.

AP line-item tagging that creates fixed-asset records at invoice approval, with device-inventory sync driving automated retirement entries.
Continuous Assertion Rule
Register assertion: fixed asset subledger net book value must reconcile to the GL asset and accumulated depreciation accounts to $0.00 at close.
