Depreciation
Allocating an asset's cost across its useful life on the balance sheet.
Two methods dominate practice: straight-line (equal expense each period) and declining balance (front-loaded). Straight-line is simpler and beloved by tax authorities; declining balance better reflects how laptops actually lose value.
AssetMon ships both methods, computes current book value live, and produces a fleet-wide CSV your finance team can hand straight to the auditor.
