Brendan T. O'Connor, the sole architect of Microsoft's Enterprise Software Advisor (ESA) channel model, claims the company’s current transition away from partner commissions lacks the safeguards that ensured the system's success in 2001. O'Connor, who designed the $5 billion licensing architecture between 1998 and 2001, argues that the total collapse of reseller commissions—falling from $2.5 billion in 2023 to $1.67 billion in 2024, $583 million in 2025, and zero in 2026—is a structural error that risks alienating necessary channel expertise.
Writing for The Register, O'Connor detailed how he built the original direct-billing model within Worldwide Licensing and Pricing to convert the EA channel from an indirect, margin-based reseller structure to a direct-billing, advisory-fee structure. The architecture included a compensation model, a specific fee schedule, and a three-tier segmentation covering 75,000 accounts across 24 countries. The ESA designation remains named verbatim in Microsoft's FY2025 10-K, twenty-four years after its launch.
"The 2001 transition included a specific mechanism designed to preserve channel expertise and align partner incentives with the new model," O'Connor stated. "The 2026 transition does not."
To move away from the unsustainable 2.2 percent margins of the late 90s, O'Connor looked toward insurance and automotive industry models. He designed a system where partners earned fees for defined advisory activities rather than transaction margins, redirecting expenditure from volume discounts to performance-based fees. This rewarded partners who invested in compliance and deployment support.
When presented to leadership, the plan was met with significant skepticism. O'Connor recalled that Steve Ballmer initially called the proposal "a perpetual motion machine" before the financial details convinced executives of its viability. The model successfully segmented customers into three tiers—Microsoft-Led, Channel-Assisted, and Channel-Led—each with distinct fee structures ranging from 4 percent to 15 percent.
O'Connor notes that by removing these commissions, Microsoft has failed to maintain the alignment between partner incentives and customer outcomes that allowed the enterprise business to thrive for over two decades. He argues that the current 2026 transition is missing the critical components that made his original architecture work, creating a financial signature of a structural transition that threatens the partner ecosystem.
