IBM licensing advisory and optimization is the buyer-side work of right-sizing your Passport Advantage estate, fixing your PVU and sub-capacity position, and removing avoidable spend before a renewal or audit. This directory lists the independent firms that advise on IBM — covering PVU, ILMT, sub-capacity and bundling — each with balanced pros and cons, in neutral order.

IBM prices much of its Passport Advantage portfolio — WebSphere, Db2, MQ, Cognos, Maximo and the rest — by Processor Value Unit (PVU), a per-core metric weighted by processor type. The single most important optimization lever is your sub-capacity position: licensing the virtual cores you actually run rather than every physical core in the host. Sub-capacity is only permitted if the IBM License Metric Tool (ILMT) is deployed and reporting within 90 days; without it, IBM is entitled to charge full capacity, which can multiply the number. A clean, defensible PVU and ILMT position is therefore the foundation of optimization, because it closes a compliance gap IBM would otherwise price into every renewal.
From there, advisory work targets the rest of the estate: products you are over-licensed on and can retire, Software Subscription & Support (S&S) you are paying for on shelfware, bundling inside an Enterprise Software Agreement (ESA) that no longer matches usage, and the metric conversions IBM proposes when you virtualize or move platforms. Because IBM now owns Red Hat, RHEL and OpenShift renewals are increasingly co-termed and reviewed in the same exercise, so optimization that spans both can matter. The goal is a smaller, cleaner, fully defensible position before any renewal or audit lands.
An IBM advisory engagement usually starts with a baseline: what you have deployed, what your ILMT and contracts actually support, and where the two diverge. The firm builds an independent PVU and sub-capacity position, quantifies avoidable spend, and produces a prioritized remediation and optimization plan — then supports the renewal or audit that follows. Independent firms take no commission on the licenses you keep or buy; a reseller or vendor partner may run similar work inside a sales relationship, which is a trade-off to weigh. Notably, the Big-Four firms appointed by IBM to run its audits sit on the vendor side, a conflict to keep in mind when choosing buyer-side help. This page is information, not legal advice.
IBM licensing advisory sits alongside IBM audit defense when a claim is already open, IBM compliance assessment to build the PVU baseline, IBM license negotiation for the renewal itself, and the cross-vendor licensing advisory & optimization service hub.

Direct answers to the questions IBM buyers ask most.
It is the buyer-side work of right-sizing your IBM estate before a renewal or audit: building a clean PVU and sub-capacity position, identifying products you are over-licensed or under-licensed on, removing avoidable spend from Passport Advantage and Software Subscription & Support, and turning entitlement and deployment data into decisions. It is advisory and information, not legal advice.
IBM licenses much of its portfolio by Processor Value Unit (PVU). Sub-capacity licensing — paying for the virtual cores you use rather than the full physical host — is only allowed if the IBM License Metric Tool (ILMT) is deployed and reporting within 90 days. A clean ILMT and PVU position is usually the single largest optimization lever, because it removes a compliance gap IBM would otherwise charge at full capacity.
Ideally before a Passport Advantage anniversary or S&S renewal, and well before an audit, so there is time to fix the ILMT and PVU position and re-baseline the estate. Optimization work done early compounds into renewal leverage and lower audit risk.
It can. Since IBM owns Red Hat, RHEL and OpenShift subscriptions are increasingly co-termed and reviewed alongside Passport Advantage. Some firms listed here cover both, which matters where an estate spans IBM and Red Hat together.
