An asset inventory is a catalogued list of everything an organisation owns, created by physically counting and recording assets and kept current over time. It is the ground-truth exercise of asset tracking: instead of trusting what the records say, you go and look. Each item found gets identified - ideally with an asset tag fixed to it on the spot - so the next count is a scan rather than a hunt.
What an asset inventory includes
For each item in scope, a useful inventory captures: what it is, where it was found, its serial number, its condition, who appears to be using it, and roughly what it is worth. Scope matters as much as fields. Most organisations set a value floor - below it, items are counted as categories (“12 monitor stands”) rather than individuals - and decide upfront whether digital assets like software licences are in or out.
Inventory vs register
The two words get used interchangeably, but the distinction is useful. The inventory is the snapshot: what physically existed when someone walked the building. The asset register is the living record that snapshot feeds, updated continuously as items are bought, moved, repaired, and retired. The inventory answers “what do we actually have”; the register answers “what should we have, and where”. The gap between the two answers is where the problems live.
How to do an asset inventory
- Set the scope - locations, categories, value floor, and who counts what.
- Walk systematically - one room, vehicle, or store at a time, recording as you go rather than from memory afterwards.
- Label everything in scope - tagging during the count means each item is matched to one record, and identical items stop being interchangeable mysteries.
- Reconcile - compare the count to existing records and investigate every difference instead of silently editing it away.
- Set the maintenance habit - decide how changes get recorded from tomorrow onwards, or the list starts decaying immediately.
A hire company counting event equipment or a school counting musical instruments follows the same five steps; only the rooms differ.
What the count usually turns up
Every honest inventory finds the same two species. A ghost asset is on the books but nowhere in the building - lost, broken, or disposed of without anyone closing the record. A zombie asset is the opposite: real, in use, and completely undocumented. Ghosts inflate insurance and depreciation; zombies are invisible to budgets, warranties, and security. Counting exists to flush out both.
Keeping the inventory current
A one-off count decays fast, which is why the inventory feeds a maintained register and gets verified by a periodic asset audit rather than being repeated from scratch each year. The practical pattern: full count once, day-to-day updates from then on, spot checks per location or category in between. In AMPthilly, a finished count can be brought in by CSV import and each item given a printable QR label, so future checks are a phone-camera scan against the live record instead of a fresh clipboard exercise.
