The journal

What vendors do, and what to do about it.

Renewal patterns, audit tactics, contract traps, and cost benchmarks, written from the buyer side of the table. For deeper task led material, see the buyer guides and licensing concept explainers.

01
Renewal strategy

Why Renewal Preparation Starts at 18 Months

Leverage is a function of time. The pattern across hundreds of renewals: buyers who start inside 6 months pay for it.

02
Renewal patterns

When a 60 Percent Uplift Lands: A Pattern Analysis

Large uplifts are rarely arbitrary. What the quote is engineered to do, and the response sequence that moves it.

03
Audit defense

The Audit Clause You Signed and Forgot

Most audit exposure is created at signature, years before the notice arrives. The clause language that decides who controls the audit.

04
Cost optimization

MSU Optimization: Quick Wins Before the Renewal

The consumption levers worth pulling in the final months before a quote lands, and the ones that need a year to pay off.

05
IBM

IBM Tailored Fit Pricing Adoption: What Buyers Report

Tailored Fit Pricing trades the R4HA game for a committed baseline. Where buyers report it paying off, and where it locks them in.

06
Contract traps

IBM Contract Traps to Avoid

The recurring clause patterns in IBM mainframe agreements that cost buyers at renewal, and how to neutralize them before signing.

07
Contract traps

Broadcom (CA) Contract Traps to Avoid

Portfolio bundling, escalators, and consumption true ups: the Broadcom (CA) contract language that deserves a second read.

08
Contract traps

BMC Contract Traps to Avoid

Suite bundles age badly. The BMC agreement patterns that quietly widen the gap between what you pay for and what you run.

09
Corporate events

Splitting the Estate: Licensing Through a Divestiture

Divestitures turn one license position into two, and vendors typically price the split. The protections to negotiate before the deal closes.

10
Product renewals

IMS Renewal Negotiation: What Moves the Number

IMS estates are sticky and IBM knows it. The levers that still move an IMS renewal despite the switching cost story.
