How to Record High-Value Capital Spares (Strategic Inventory)

Accounting for critical, high-cost components (e.g., specialized lenses or vacuum pumps) held for the immediate repair of Fab tools.

💡 Accountant's Note

In a Fab, one hour of downtime can cost $1M. Companies keep 'Capital Spares'—expensive parts ($10k-$500k each) that are not used in daily production but are essential for the machine's long-term operation. Under GAAP, these are classified as Fixed Assets (not Inventory) because they are expected to be used for more than one year. They generally are not depreciated until they are physically 'installed' into a machine.

Practitioner & Systems Framework

💻 ERP Architecture

Set these up in the Fixed Asset module with a 'Pending Installation' status. When the part is swapped into a tool, you start depreciation, and the 'old' broken part is retired/scrapped.

⚠️ Audit Flags

Physical Counts. Because these parts are high-value and portable, they are prime targets for theft or loss. Auditors will perform a 'Wall-to-Wall' count of the Capital Spares room.

📄 Required Documentation

Strategic spares list, purchase invoice, and the 'Inventory vs. Capital Spare' policy memo.
