The indictment. The industry case. The methodology. Each book examines the same underlying disruption from a distinct vantage point - B2B sales, technology services, and the operating system built to navigate both.
This is the thesis that runs through all three books. Death by Execution documents the inversion in B2B sales. The Last Billable Hour documents the inversion in technology services. Inversion Selling™ is the operating system built for what comes after both inversions. They can be read independently. They are designed to be understood together.
"The profession was built on controlling information the buyer couldn't access. The internet gave buyers everything. The methodology didn't update. The profession collapsed."
Death by Execution is the indictment. For over a century, B2B selling operated on a foundational premise: the seller held information the buyer needed. That asymmetry is what justified the methodology, the compensation model, and the professional identity. The internet inverted that premise in a decade. Every methodology built on information asymmetry became not just ineffective but actively harmful - creating buyer resistance where it was meant to create momentum.
The book documents the collapse and names the only surviving professional identity: the Buying Advisor - a professional whose value is not the information they hold, but the judgment they exercise on behalf of the buyer. The judgment that AI structurally cannot replicate because it requires bearing accountability for advice.
"A $1.5 trillion industry built on one premise: skilled labor is scarce and buyers will pay a premium for access to it. AI eliminated that premise. The billing model, the org structure, and the value proposition all collapsed together."
The Last Billable Hour is the industry case. Technology services - consulting, staffing, outsourcing, managed services - was built on a foundational premise: engineering labor is scarce. The billable hour was the commercial expression of that scarcity. AI has not disrupted this industry. It has inverted the premise.
The book maps the inversion in detail - the Jefferies analysis, the $50 billion session, the lag period firms are currently navigating - and describes what the firms that survive will look like. The Three-Zone Revenue Portfolio applied to a $1.5 trillion industry.
"Every methodology that existed before 2015 was designed for a world where sellers controlled information. That world ended. This is the operating system for what replaced it."
Inversion Selling™ is the third book - and the operating system. Built from 11 years of field observation across hundreds of B2B engagements. 150,000 words. 14 laws. A complete pipeline redesign. Currently under review at the University of Houston Sales Excellence Institute for behavioral science validation.
The book is not a collection of techniques. It is a complete replacement of the commercial operating system - hiring profiles, onboarding, pipeline architecture, compensation design, coaching cadence, and measurement framework. Everything aligned around the Buying Advisor identity and Revenue Physics™.
As Fractional CGRO, I install Inversion Selling™ into the commercial function. The book is the documentation. The engagement is the installation. You don't have to wait for 2026.
