What is the difference between a CFO and a controller?
A controller is the senior accounting leader responsible for accurate financial reporting; a CFO is the senior finance executive responsible for strategic financial direction.
Quick answer
A controller manages historical accounting (close, statements, audit, compliance), while a CFO is forward-looking (forecasting, capital allocation, M&A, strategy). Most growing clinics need both, sequenced controller first.
The detail
The simplest distinction: a controller answers what happened, a CFO answers what should happen next. Controllers own the monthly close, the financial statements, the audit, tax coordination, and accounting compliance. CFOs own the forecast, capital allocation, payer contract economics, M&A modeling, banking relationships, and board or partner reporting. Compensation reflects scope: BLS data shows accountants and auditors median wage of $81,680 in May 2024, while financial managers median wage was $161,700. In a clinic, a strong controller often costs $90K to $140K and is the foundation; without clean books, CFO work is impossible. A fractional CFO at $4K to $8K per month layers on top to provide strategic direction. Most clinics under $5M in revenue should hire or outsource the controller role first, then add a fractional CFO when forecasting and capital decisions become recurring needs.

What this means for clinic owners
From Sorso
Hiring a CFO before you have a controller is like hiring a strategist with no data. Sequence matters. Get the books clean first, then add forward-looking finance.
