When Does a Small Business Actually Need a CFO?
Most small business owners under-hire on finance for years, then over-hire in a single panicked decision. The result: either a bookkeeper trying to do work they were never trained for, or a CFO making twice the salary of the next-highest paid employee with not enough work to justify the seat. There is a sequence — and a logic — that works better.
The actual hierarchy of finance roles
Bookkeeper records what happened. Reconciles accounts. Closes the books. Files compliance items. Usually $40-80K/year or $50-150/hour part-time. Most businesses under $2M in revenue need only this.
Controller owns the close, builds management reports, manages the bookkeeper, runs the audit and tax-prep cycles. Usually $90-160K/year. Most businesses between $2M and $20M need a controller.
Fractional CFO does strategic finance — forecasting, capital strategy, board reporting, M&A support — on a part-time basis. Usually $3-15K/month. Useful when the business needs CFO capability but cannot justify the salary.
Full-time CFO integrates strategic finance into daily operations, leads capital raises, manages the finance team. Usually $200-500K all-in. Justified when revenue exceeds $25-50M, or when the business is in a transaction mode (preparing to sell or raise meaningfully).
Three signals you’ve outgrown your bookkeeper
- Monthly close takes more than 20 days.
- You don’t trust the numbers and run a parallel “real” version in your head.
- Tax prep requires three times the expected hours every spring because the books need rework.
Three signals you’ve outgrown your controller
- You’re contemplating a capital raise but don’t have someone who can build the model and run the data room.
- You’re considering an acquisition or sale and need a financial counterpart who can manage transaction diligence.
- Your board / advisors are asking for analysis the controller doesn’t have time to produce.
The sequence that works
Most businesses follow this path: bookkeeper → bookkeeper + outside CPA → controller (in-house or fractional) → controller + fractional CFO → full controller and full CFO team. Skipping steps usually creates problems. Adding a full CFO at $3M revenue burns cash and bored the executive. Keeping a bookkeeper at $20M creates the kind of financial chaos that ends businesses.
What to do this quarter
If you’re under $2M and the books are clean: stay with the bookkeeper plus a good CPA.
If you’re $2-20M and the books are not clean within 15 days of month-end: hire a controller (or upgrade your bookkeeper).
If you’re $5M+ and contemplating a transaction or capital event in the next 12 months: engage a fractional CFO now to prepare.
