Your vendors negotiate mainframe agreements every week. You face them once every three years. We close that gap.

Mainframe Licensing Experts was established in 2019 to do one thing: put real licensing expertise on the buyer side of mainframe software negotiations. The publishers who sell into the mainframe estate run disciplined, well staffed commercial machines. Most enterprises meet that machine with a procurement generalist and a renewal date. The result is predictable, and it is priced into every uplift letter the industry sends.

We sit on your side only. We are paid by clients, never by vendors, and we are not affiliated with IBM, Broadcom, BMC, Rocket Software, Software AG, or Precisely. That independence is structural, not rhetorical: it is what lets us challenge an audit methodology, recalculate a finding, or recommend walking away from a product line without any conflict in the room.

The work concentrates on two disciplines, mainframe audit defense and license negotiation, supported by renewal advisory, cost optimization, contract review, and MSU optimization. Everything we know about one publisher's tactics compounds across the others, because the playbooks rhyme: capacity baselines that ratchet, bundles that hide shelfware, and clocks that always favor the vendor.

How the work runs

Our approach in full →
01

Baseline

Full portfolio inventory: every product, every contract, MIPS or MSU per product, term expiry per agreement. Most estates have never seen their own position on one page. This is where leverage starts.

02

Reconcile

Actual consumption against contracted capacity, with SCRT and R4HA data validated independently. Vendor reported numbers are the vendor's case; reconciled numbers are yours.

03

Leverage

Alternative evaluation, metric transition options, timing, and the credible walk away, built before the vendor controls the clock. Leverage that arrives in the final quarter is theater; leverage built early moves numbers.

04

Close

The renewal or settlement locked with caps, consumption protections, and exit rights. A good close protects the next term, not just this one.
