At One Abacus Advisory, our Fractional Senior Finance Director and Controller services provide nonprofits with experienced, hands on financial leadership without the cost of a full time hire. This role focuses on translating financial strategy into consistent execution—strengthening systems, improving reporting, and ensuring financial operations are reliable, compliant, and well managed.
Unlike Fractional CFO services, which emphasize executive level strategy and board partnership, this role centers on day to day financial leadership and operational excellence.

How This Differs from a Fractional CFO
- Fractional CFO: Focuses on high-level financial strategy, long term planning, and board advisory
- Senior Finance Director / Controller: Focuses on financial execution, reporting integrity, internal controls, and team leadership
Many nonprofits begin with Controller‑level support to establish strong financial operations and add CFO‑level guidance as strategic complexity grows.
