Document your estate before the auditor asks.

The companies that settle audits cheaply are the ones that already know their own estate. Here is the record to build now, while you control the timeline rather than IBM.

An audit is an evidence contest, and the side with the better records wins more lines. The problem is that most estates are documented under pressure, after the notice arrives, when there is no time to find a missing proof of entitlement or reconstruct two years of sub capacity reports. The fix is to build the record before anyone asks for it.

The four records that matter

Entitlement ledger. A single authoritative list of every IBM entitlement you hold, with quantity, metric, and the Passport Advantage site it sits under. This is the number IBM most often understates, so owning a clean version of it is leverage.

Proof of entitlement documents. The PoE is what actually proves you bought a license. Keep them filed against the ledger, including the ones inherited through acquisitions and migrations, which are the easiest for IBM to overlook.

Deployment map. What is installed, on which hosts, at what capacity, under which virtualization layer. This is what the data collection tool will measure, so knowing it in advance lets you catch the tool's errors instead of inheriting them.

Sub capacity evidence. Continuous tool reports, retained for two years, proving you are entitled to license virtual cores rather than full hosts. A gap here is the most expensive single failure in IBM licensing.

Why timing is the whole game

When you document the estate on your own schedule, you can correct a miscategorized install, recover a lost PoE, or close an ILMT gap quietly. Once the audit clock starts, every one of those becomes a finding you are defending under deadline. Documentation done early is remediation. The same work done late is damage control.

Keep it current

• Refresh the deployment map whenever a major workload moves or a host is resized.
• Reconcile the entitlement ledger against Passport Advantage at least once a year.
• Verify sub capacity reports are generating and retained, not silently broken.
• Capture entitlements from any acquisition the moment it closes, before the records scatter.

None of this is glamorous, but it is the difference between negotiating from evidence and negotiating from memory. The estate record is the asset that makes every later defense cheaper.
