Mr. William Mark Mayo, Contracting Officer

William M. Mayo serves as a Contracting Officer with the Defense Finance and Accounting Service (DFAS), where he plays a critical role in executing financial management and operational support acquisitions aligned with the Department of Defense’s fiscal accountability mission. He manages a diverse portfolio of contracts supporting automated accounting systems, compliance reporting tools, and financial infrastructure modernization initiatives. His work ensures that DFAS maintains audit-ready, secure, and scalable financial operations across military and civilian programs, with a focus on performance-based acquisitions governed by FAR Part 16 and performance work statements. Mr. Mayo maintains established relationships with a range of vendors, including Soderberg Company Inc., Ecology Mir Group LLC, Bloomberg Industry Group, Inc., and Roche Diagnostics Corporation, reflecting a mix of technical, administrative, and specialized service providers. His contracting patterns emphasize long-term vendor partnerships grounded in clear performance metrics and compliance with federal acquisition regulations, particularly in areas requiring high data integrity and system interoperability. He frequently engages contractors with proven experience in financial systems integration, regulatory reporting, and mission-critical service delivery. While the majority of his acquisitions are conducted under full and open competition, Mr. Mayo consistently allocates 20% of his portfolio to Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to small business participation without reliance on specialized socioeconomic programs like 8(a) or HUBZone. His approach prioritizes capability over certification, ensuring competitive rigor while expanding access for qualified small firms. His primary procurement focus spans NAICS 541512 (Computer Systems Design Services), 541930 (Translation and Interpretation Services), 624120 (Services for the Elderly and Persons with Disabilities), 238390 (Other Building Finishing Contractors), and 522110 (Commercial Banking). This reflects a broad operational need for IT modernization, multilingual administrative support, facility maintenance, and financial services infrastructure—all critical to sustaining DFAS’s mission of secure, efficient financial operations across the DoD.
