Marsh McLennan

Marsh McLennan, the world's largest insurance broker and risk advisory firm with approximately $20 billion in revenue (2022) and over 85,000 employees across its Marsh, Guy Carpenter, Mercer, and Oliver Wyman operating companies, had a complex third-party spend profile. Each operating company historically managed its own vendor relationships independently — four separate sets of technology vendors, office suppliers, professional services firms, travel providers, and data suppliers. Total third-party spend across the enterprise ran into billions annually, but the four operating companies rarely coordinated procurement, leaving significant savings on the table. Additionally, the rapid growth through acquisitions (Jardine Lloyd Thompson in 2019 for $5.6 billion being the largest) brought additional vendor relationships that further fragmented the supply base. SG&A as a percentage of revenue was an area of ongoing focus for management seeking to improve operating leverage.

Between 2020 and 2023, Marsh McLennan executed a cross-company vendor rationalization program as part of its broader operational efficiency initiative:

• Enterprise procurement function: Established a centralized procurement organization with authority to negotiate enterprise-wide contracts across all four operating companies. Previously, each company negotiated independently — meaning Marsh and Mercer might pay different rates for the same software platform or consulting firm.
• Technology vendor consolidation: Consolidated enterprise technology spend onto fewer, larger platform relationships. Standardized on core platforms for CRM, HR, finance, and collaboration tools across operating companies, replacing duplicate licenses and reducing per-seat costs through volume aggregation.
• Data and analytics vendor rationalization: Consolidated overlapping data subscriptions and analytics tools across Marsh (insurance data), Mercer (HR/benefits data), and Oliver Wyman (research databases). Multiple operating companies were paying for overlapping market data, economic data, and industry research from the same providers.
• Travel and professional services: Negotiated enterprise-wide agreements for travel management, legal services, and management consulting, replacing operating-company-level contracts with group-level deals that reflected Marsh McLennan's true scale.
• JLT integration synergies: Used the JLT acquisition integration as an opportunity to renegotiate vendor contracts at the combined entity's higher volume, with JLT integration delivering over $400 million in annualized cost savings by 2022 (including but not limited to vendor rationalization).

• JLT integration savings: Total annualized cost synergies from the JLT acquisition exceeded $400 million by 2022, surpassing the original target, with vendor rationalization contributing alongside headcount and real estate optimization.
• Operating margin expansion: Adjusted operating margin expanded from approximately 21% (2019) to over 28% (2023), reflecting sustained operational efficiency improvement including procurement optimization.
• Revenue growth with operating leverage: Revenue grew from $16.7 billion (2019) to $22.7 billion (2023), a 36% increase, while costs grew more slowly — demonstrating the operational leverage from vendor rationalization and other efficiency initiatives.
• SG&A efficiency: SG&A as a percentage of revenue improved as centralized procurement reduced per-unit costs across categories.
• Vendor count reduction: The number of active vendor relationships decreased meaningfully as duplicative contracts were consolidated, reducing administrative overhead in procurement, legal, and accounts payable.
• Timeframe: Vendor rationalization program executed over 2020-2023, with JLT integration savings largely captured by 2022.

• JLT acquisition provided both the mandate and the opportunity for cross-company vendor rationalization, as integration naturally required reviewing all vendor relationships
• CEO Dan Glaser's focus on operating efficiency and margin expansion provided sustained executive sponsorship for procurement initiatives
• Marsh McLennan's scale as the largest company in its industry provided genuine volume leverage with technology, data, and service vendors
• The professional services business model (primarily people costs with significant third-party spend) meant that procurement savings flowed directly to operating margin
