IT asset management
The register exists to answer operational questions: what do we have, who has it, is it supported, is it licensed, and when does it need replacing. An inventory that answers none of those is an accounting artifact.
One register, reconciled against reality
A register maintained by hand diverges immediately. Feed it from discovery — what is actually on the network and enrolled in management — and reconcile against procurement and finance records.
The valuable output is the discrepancy list: assets in the register that discovery cannot find, and devices discovery finds that the register does not know about. The second category is the security problem, since an unknown device is unmanaged by definition.
Ownership, not just location
Every asset needs a named accountable person. "The engineering team" is not an owner; when the device needs patching, returning or replacing, a team does not answer.
Track state through the lifecycle — ordered, in stock, assigned, in repair, retired, disposed — and require the state change at the moment of handover. A register updated in batches is a register that is wrong between batches, which is most of the time.
Software licensing
Under-licensing is a financial and legal exposure that surfaces at audit; over-licensing is money spent on nothing, and it is usually the larger number.
Reconcile entitlements against actual installs and actual use. Reclaiming licenses from people who stopped using a tool typically funds a meaningful fraction of the next renewal, and the data for it already exists.
Watch license models that change cost with infrastructure — per-core, per-socket, per-user in a system that provisions freely. A routine infrastructure change can multiply a license bill with no procurement decision anywhere in the path.
Refresh and disposal
Plan refresh on a cycle and budget it as a steady cost through
finance:budgeting-and-forecasting. Refresh driven by failure produces an unpredictable expense and
a worse experience, and it always arrives at the wrong moment.
Disposal is where data escapes. Require certified destruction or verified wipe, keep the certificate, and treat storage devices as data until proven otherwise. A drive in a cupboard nobody logged is a breach with no date attached.
Tooling
Discovery and hardware inventory: Lansweeper, Snipe-IT, ServiceNow ITAM, Device42, and similar; the endpoint management platform already knows most of the fleet and is the cheapest starting point.
Software licensing and SaaS spend: Flexera, Torii, Zylo, Productiv, and similar. The SaaS half is where the money hides, and it is discovered through the expense system and single sign-on logs as much as through any inventory tool.
Reconcile the register against the endpoint platform, the identity provider and the finance system on a schedule. Three systems each holding a partial truth is the normal state, and the gaps between them are the assets nobody is managing.

references/sources.md in this skill lists the outside authorities that settle the questions
here — what each one is authoritative for, and what you may do with it. Check them before
answering on anything they cover, and cite what you used. Most are free to read and not free
to reproduce; the use note on each is binding.
Never
- Maintain a register by hand and trust it.
- Record a team as an asset owner.
- Renew licenses without reconciling against actual use.
- Dispose of storage without evidence of destruction or wipe.
