① IBM · Audit defense
An IBM license review on the mainframe turns on data: SCRT reports, SMF records, entitlement history. Whoever masters that data first controls the outcome. We make sure that is you, starting within 48 hours of the notice.
The audit is framed as verification. The mechanics are commercial.
IBM mainframe compliance turns on sub-capacity reporting. If you license z/OS, CICS, Db2, IMS, or MQ below full machine capacity, monthly SCRT submissions document the peak rolling four hour average per product. Where reporting lapsed, where an upgrade changed the capacity picture, or where entitlements drifted from deployment, exposure accumulates quietly, and a review notice typically arrives at the moment it is most valuable to the vendor: before a renewal, after a divestiture, or following a visible drop in spend.
The opening findings commonly assume the worst supportable interpretation: full capacity charges for unreported periods, list pricing for gaps, growth assumptions resolved against you. None of that is final. It is an opening position, and it deserves an answer built from your own data, the patterns of which are described in our sub-capacity explainer.
Within 48 hours: one named point of contact, all auditor communication routed through it, internal teams briefed on what not to volunteer. The notice is acknowledged without conceding scope, timing, or methodology.
Nothing leaves the building unreviewed.
Every data request is mapped against the audit clause that authorizes it. Requests commonly exceed entitlement; what is owed gets provided in the form that is owed, on a timeline you can actually meet.
The contract sets the rules, not the auditor.
We reconstruct your true position from SMF records, SCRT history, and the full entitlement chain before the auditor presents theirs. Reporting gaps get reconstructed from the underlying data instead of surrendered to full capacity assumptions.
You see your number before they show theirs.
Findings rest on assumptions: measurement windows, aggregation choices, pricing applied to gaps. Each assumption gets tested against the contract and the data. In our experience, vendor audit math rarely survives a serious recalculation intact.
Every assumption pays rent or leaves.
What remains after recalculation gets negotiated, typically as future contract value, pricing protections, or terms you wanted anyway, rather than a back charge. The settlement also closes the gaps that created the exposure, so the next review starts clean.
An ending that improves the next agreement.
③ What changes with us in the room
The auditor has run hundreds of these. Now so have you. That is the whole difference.

Mainframe spend negotiated on the buyer side
Patterns we commonly observe: a significant drop in IBM spend, a hardware upgrade or migration, mergers and acquisitions, lapsed or inconsistent SCRT submissions, and elapsed time since the last review. The framing is collaborative; the mechanics are commercial. Manage it as an audit.
Unreported periods can be treated as full capacity, which is the single most expensive assumption in mainframe audits. The exposure is frequently negotiable: SMF data usually still exists to reconstruct actual consumption, and a reconstructed position beats a full capacity default. Engage before responding.
Not reflexively. Requests commonly exceed contractual entitlement. We map each request to the audit clause, analyze everything ourselves first, and provide what is owed in the form owed. You should never learn what your own data shows from the auditor.
Opening findings are a negotiating position. Independent recalculation, methodology challenges, and corrected entitlement records typically reduce them materially, and remainders often settle as future contract value rather than back charges. Across 500+ engagements the pattern is consistent. See the shape of it in our case studies.
