CBIZ, Inc.
CBIZ, Inc. (CBZ)
Overview
CBIZ, Inc. is a national professional services firm serving middle-market businesses, operating through more than 9,500 team members across more than 140 locations in 23 major U.S. markets. The company was significantly reshaped by its 2025 acquisition of Marcum LLP, one of the largest independent accounting firms in the country, which substantially expanded CBIZ's scale and market presence in accounting, tax, and advisory services. For fiscal 2025, total revenue split roughly 85.1% ($2.348 billion) from the Financial Services segment and 14.9% ($409.6 million) from Benefits and Insurance Services. Like many accounting-industry participants, CBIZ operates via Administrative Service Agreements with independent CPA firms — providing administrative, technology, and staffing support in exchange for fees, since CPA firms themselves must remain independently owned by licensed accountants under U.S. professional-licensing rules.
What They Do & How They Make Money
CBIZ earns fee-based revenue for professional services delivered to middle-market clients. The Financial Services segment provides accounting, tax, valuation, transaction advisory, technology consulting, and government healthcare consulting — work that recurs annually as clients require ongoing tax compliance, audit, and advisory support. The Benefits and Insurance Services segment offers employee benefits consulting, payroll and human capital management outsourcing, property and casualty insurance brokerage, and retirement plan services. Management emphasizes that a significant portion of CBIZ's revenue is recurring in nature, reflecting the fact that businesses rarely change accounting, tax, or benefits providers except for cause, which supports predictable, compounding revenue growth through both organic client retention/cross-selling and continued acquisitions.
Business Segments
- Financial Services — Accounting, tax, valuation, and advisory services delivered to middle-market businesses, substantially expanded by the 2025 Marcum acquisition; approximately 85% of 2025 revenue.
- Benefits and Insurance Services — Employee benefits consulting, payroll/HCM, P&C insurance brokerage, and retirement services; approximately 15% of 2025 revenue, offering diversification away from pure accounting-cycle dependency.
Competitive Landscape
CBIZ competes with a wide spectrum of professional services providers: the Big Four and other large national accounting firms for larger clients, independent regional and local CPA firms for smaller engagements, other national consolidators pursuing similar roll-up strategies in accounting and benefits, and clients' own in-house finance and HR functions as an alternative to outsourcing. The professional services industry remains highly fragmented, with thousands of independent practices nationally, meaning no single competitor dominates the middle-market segment CBIZ targets.
Competitive Position
CBIZ's principal strength is the high switching cost inherent in outsourced accounting, tax, and benefits relationships — clients face real disruption, historical-data migration burdens, and relationship risk in changing providers, which supports strong client retention once onboarded. The Marcum acquisition materially increased CBIZ's scale and brand recognition in mid-market accounting, a further competitive advantage versus smaller regional firms. Recurring revenue and cross-selling opportunities between Financial Services and Benefits and Insurance Services add resilience. Offsetting these strengths, the company's own 10-K discloses material weaknesses in internal controls over financial reporting following its rapid scale-up, alongside typical professional-services risk around retaining key executive and partner talent. CBIZ's path forward depends on successfully integrating Marcum, remediating its internal-control weaknesses, and continuing to cross-sell across its now-larger combined client base.
