A fractional CFO is a part-time, contract-based Chief Financial Officer who provides strategic financial guidance, typically to businesses that need CFO-level expertise but cannot justify or afford a full-time hire. The role covers strategic planning and financial oversight on a defined schedule rather than a full-time employment relationship.

Fractional CFO
How a fractional CFO is defined
Tipalti defines a fractional CFO as someone "typically hired on a contractual basis to share their expertise in finance, strategic planning and other CFO-related activities" (Tipalti). NerdWallet frames the value proposition from the buyer's side: a fractional CFO "provides services to businesses that don't require, or can't afford, a full-time CFO," delivering "strategic financial guidance on a part-time, contractual or project basis" (NerdWallet).
The role sits above bookkeeping and outsourced controller work in scope. Where a bookkeeper records transactions and a controller manages reporting and compliance, a fractional CFO focuses on forward-looking strategy: cash flow forecasting, pricing strategy, fundraising support, and board-level financial guidance, delivered without the cost or commitment of a full-time executive.
Where fractional CFO work fits in the advisory landscape
Within the accounting industry's own client advisory services (CAS) framework, virtual or outsourced CFO advisory is a named, recognized offering, not an informal add-on. CPA.com's CAS maturity model places "CFO Finance," "CFO Business Insights," and "Trusted Business Advisor" as distinct levels a firm can grow into (CPA.com; Thomson Reuters, citing CPA.com). This means fractional CFO work is not a separate category from accounting advisory; it is one recognized point along the same advisory spectrum accounting firms already operate in.
What a fractional CFO typically charges
Pricing varies widely by scope and market, and figures from individual consulting-firm blogs, commonly cited in ranges like $3,000 to $15,000 a month or $200 to $500 an hour, should be treated as illustrative rather than authoritative, since they are not drawn from a single standardized survey. For a sourced, three-tier pricing ladder specifically for a fractional CFO diagnostic-to-retainer offer, including diagnostic, pilot, and retainer pricing cited to named sources, see fractional CFO client acquisition.

Frequently asked questions
Is a fractional CFO the same as an outsourced bookkeeper?
No. A bookkeeper records and reconciles transactions. A fractional CFO focuses on forward-looking financial strategy, such as cash flow forecasting and pricing decisions, at a more senior scope than bookkeeping or basic controller work.
How many hours a week does a fractional CFO typically work for a client?
This varies by engagement and is set by contract rather than a fixed industry standard. Fractional arrangements are defined by scope and deliverables rather than a universal hours commitment.
