These terms are often used interchangeably, but they describe different arrangements: Fractional CFO — an ongoing, part-time CFO relationship, a long-term financial partner who grows with your business. Interim CFO — a temporary, usually full-time CFO filling a gap, such as while you search for a permanent hire. Virtual CFO — a CFO who works remotely rather than on-site; this describes delivery method, not commitment level, and can apply to either a fractional or interim engagement. Outsourced CFO — a broad term for any CFO function delivered by an outside firm rather than an employee; fractional is one form of it. For most growing businesses, the fractional model — ongoing, part-time, relationship-based — is the one that fits.
