What is the difference between a fractional CFO and a bookkeeper?

A bookkeeper is a backward-looking role. They categorize every transaction, reconcile bank and credit card accounts, run accounts payable and accounts receivable, prepare payroll inputs, close the month, and produce P&L, balance sheet, and cash flow statements. The job is data integrity. Without a bookkeeper, your books are wrong, and every downstream decision is built on bad numbers. A fractional CFO is a forward-looking role. They take the closed books a bookkeeper produces and use them to build financial models, forecast cash flow, track KPIs, analyze unit economics by location and provider, model expansion or exit scenarios, and recommend specific actions each month. The job is decision support. Without a CFO, you have accurate numbers but no clear plan for what to do with them. The two roles compete for budget but not for scope: a bookkeeper replaces no part of CFO work, and a CFO replaces no part of bookkeeping work. Whether you need both depends on whether the owner can do the strategic thinking themselves with clean books, or whether the next decision (a second location, a partner buyout, a new line of service) is large enough to justify a CFO. For scale, Sorso builds its accounting service for practices with $0.5M to $10M in revenue and its fractional CFO service for $3M to $50M. Healthcare adds complexity. A general bookkeeper can handle the transactions but rarely understands payer mix, denial tracking, contractual adjustments, or location-level provider economics. A healthcare-specialized bookkeeper or accountant produces books that already reconcile to the practice management system, which makes the CFO's downstream work meaningfully faster and more accurate.
