With a financial team that is matched to your unique needs and a flexible contract that can scale services (up or down) as your organization requires, you can address your finance, revenue generation, development, board engagement, and growth challenges. We offer the specialized nonprofit financial consulting support that many medium to large organizations require to support their mission.

Charles River CFO provides nonprofit accounting services to organizations that offer a variety of services to their members and the community, including foundations, professional and trade organizations, public charities, social advocacy organizations, and Flexible Benefit Corporations.

"The Waldorf School of Lexington greatly benefited from the financial leadership and expertise provided by Charles River CFO. Faced with both the demands of the COVID pandemic and a financial staff transition, their expertise was essential in supporting our operations, navigating important PPP government funding, and in preparing for and managing our audit process. In addition, they were essential as we sourced and hired our permanent financial staff."
