What Capitol Business Solutions does

Capitol Business Solutions Inc. (CBS) is a small, woman-owned management consulting firm headquartered in Arlington, Virginia, founded in 2000 by Esther L. Lehman. The firm operates through two service groups: the Management Consulting Group, which delivers financial management, accounting, budget formulation and execution, general administration, and program management services to U.S. Federal Government Agencies; and the Aviation Group, founded and led by Dayton Lehman Jr., which provides legal and management consulting on DOT regulatory compliance, enforcement, consumer protection, disability regulations, management fitness, and economic licensing for aviation industry clients. The company holds a GSA Schedule contract (GS-23F-0007U) under Federal Supply Group 520 that allows federal agencies to procure its services directly.

CBS does not disclose a proprietary technology platform; service delivery relies on Microsoft Office tools (Access, Excel, Word) for reporting and standard federal financial systems (CARS, MAX, IPAC) for transaction processing and reconciliation. Functional capabilities include OMB Circular A-11 and A-136 compliance, FACTS I, FACTS II, and GTAS preparation, production of auditable financial statements, internal controls assessment, financial system design and implementation, and GPRA/GPRA Modernization Act support. Core service offerings are: Management Consulting Group (financial and program management for federal agencies) and Aviation Group (DOT regulatory and legal consulting).

The business model is professional services revenue earned through federal contracting vehicles, with quote-based pricing under the GSA Schedule. The go-to-market motion is enterprise direct sales driven by long-standing agency relationships; the Presidents of each service group are integrally involved in every engagement. The disclosed client base is concentrated among U.S. DOT sub-agencies, including the Maritime Administration, Office of Small and Disadvantaged Business Utilization, Vehicle Research and Test Center, and Bureau of Transportation Statistics, plus the National Capital Planning Commission. The company operates with a headcount of 1–10, is actively hiring a Staff Accountant/Analyst, and reports no external funding or institutional investors.
