Zombie assets
Zombie assets are assets that exist within a company but were never added into a depreciation schedule on the company's balance sheet.
Ghosts assets
Ghost assets are those that are visible on the balance sheet but can't be physically located.
A business can easily carry tens of thousands of dollars in untracked assets if the asset lifecycle isn't monitored closely or analyzed frequently.  A fixed assets tracking solution allows a business to dispose of, retire, and transfer assets easily.
