IBM software asset management is the ongoing, buyer-side discipline of keeping your IBM estate accurately measured and license-compliant between audits — above all keeping the IBM License Metric Tool (ILMT) deployed and reporting so sub-capacity licensing holds. This page explains what an IBM SAM engagement covers, lists the firms that run it with balanced pros and cons, and gives indicative outcomes — a directory, not a ranking.

IBM SAM keeps the Passport Advantage portfolio measured in Processor Value Unit (PVU) terms and the ILMT evidence current, so an audit finds a defensible position rather than a gap.
Keep ILMT installed, discovering and reporting within IBM's required window (commonly cited as 90 days). A current ILMT report is the evidence that sustains sub-capacity licensing.
Track Processor Value Units across physical and virtual hosts as the estate changes, rather than scrambling to reconstruct counts when a review lands.
Maintain a clear map of which deployed features are entitled bundle components and which are separately licensable, so nothing is silently over- or under-licensed.
Watch dynamic infrastructure: vMotion, cluster expansion and container sprawl can pull workloads onto un-reported cores and break a sub-capacity claim.
Reconcile deployment against your Passport Advantage entitlement on a schedule, keeping an Effective License Position you can defend.
Govern new deployments and procurement intake so growth is licensed before it ships, not after an auditor counts it.
Around 62% of companies were audited by a major vendor in the last 12 months, and roughly 42% of organisations report having been audited by IBM at least once (2025 surveys; LicenseFortress / Block64). About 52% of buyers now bring in outside help. Figures are survey-reported for the years shown.
Ongoing and buyer-side, scoped to your estate. Many engagements run as a managed service so ILMT and the PVU position stay current rather than degrading between reviews.
The firm inventories your IBM estate, checks ILMT deployment and reporting coverage, and reconciles it against Passport Advantage entitlement to set a defensible starting position.
Gaps in ILMT coverage, stale agents and un-reported hosts are fixed; tagging, discovery and reporting are instrumented so the sub-capacity position stays evidenced.
An ongoing cadence maintains the Effective License Position, flags drift, and feeds renewals and any audit response with clean data.

Keeping ILMT current is the single highest-value control, because a missing or stale report is what lets IBM charge full capacity on every eligible core.
Walking into a review with a current PVU position and ILMT evidence typically shortens the audit and narrows the disputable surface.
An accurate license position lets you renew Software Subscription & Support to real need rather than to an inflated baseline.

IBM software asset management is proactive and ongoing: it keeps your estate measured, your ILMT reporting current and your Effective License Position defensible between reviews. Audit defense is reactive: it contests a specific IBM claim once a review is open. Good SAM is what makes an eventual audit smaller and cheaper, and several firms listed here do both.
Sub-capacity licensing — paying for the virtual cores a product uses rather than every physical core in the host — is conditional on the IBM License Metric Tool being deployed and producing reports within IBM's required window. If ILMT is missing or stale, IBM can charge at full capacity, which is the most expensive IBM finding. Keeping ILMT healthy is therefore the core control an IBM SAM engagement maintains.
Both are valid; the directory does not say which is better. Firms bring PVU and ILMT depth and an outside line of sight, while an in-house team owns the estate daily. Many buyers use a firm to set the baseline and instrument ILMT, then run governance internally with periodic external reconciliation.
It can. Red Hat is owned by IBM, but it uses its own subscription model (per socket-pair or per-instance) rather than PVU, so it is governed differently. Several firms listed here cover both IBM and Red Hat, which helps where renewals are co-termed.
The directory does not rank. It states facts to weigh: an independent firm carries no vendor partnership, reseller relationship or commission, shown as a pro; a firm that also resells tooling, or a Big-Four firm appointed to run IBM audits, carries that as a con because it is a potential conflict with buyer-side advice. Both are factual trade-offs, not a verdict.
