AI CFO vs
fractional CFO.
A fractional CFO is a person you book by the hour. An AI CFO is software that reads your books every day. They overlap on the recurring analysis and part ways at the table: the software is cheaper and always on; the person can negotiate, raise money and be accountable for the numbers.

- $99/mo vs $150–400/hr
- Every day vs when booked
- Many owners use both
The short answer
- 1
Pick an AI CFO when the job is knowing your numbers: the monthly review, the cash forecast, the questions in between.
- 2
Pick a fractional CFO when a decision needs someone in the room: a raise, a lender, a sale of the business, a hard restructure.
- 3
Use both when the person's hours are expensive. Let the software do the recurring reads so their time goes to the decisions.
Split the job by what needs a person.
Most of a CFO's month is recurring analysis; a few days of it are judgment calls with someone across the table. That line is where the software stops and the person starts.
The monthly review
What revenue, margin and profit did, which accounts moved them, and what to watch next month. Written from the books, not rebuilt in a spreadsheet.
The 13-week cash forecast
Week by week from what's owed to you, what you owe, payroll and recurring bills, kept current as the books change.
Questions in between
"Can we afford a hire?" "Why was profit down?" Answered from your own numbers at 11pm, without booking an hour.
Raising money
Building the story, sitting with investors, negotiating terms. Someone has to stand behind the numbers in the room.
Lenders and banks
A credit line, a covenant conversation, an SBA loan. The software can prepare the numbers; a person makes the case.
The big one-off calls
Buying a competitor, selling the business, a restructure. Judgment and accountability you can't get from a subscription.
Cost, cadence and what each one does.
Neither one keeps your books. Both work best on top of clean bookkeeping, and both will tell you where it needs attention.

Judgment on a big bet
Whether to take the investor's term sheet or the bank's is a call that weighs things the books don't hold.
A seat at the table
Investors, lenders and buyers want a person who can answer follow-ups and be accountable for the answers.
Context outside the books
A key customer wobbling, a co-founder leaving — software only knows it once you tell it.
Your bookkeeping
Neither an AI CFO nor a fractional CFO keeps the books; you still need a bookkeeper or accountant.

More on AI CFOs
Questions, answered.
Is an AI CFO cheaper than a fractional CFO?
Usually by a wide margin. AI CFO software for small businesses typically costs $29 to $250 a month; a fractional CFO typically bills $150–400 an hour, often $3,000 or more a month. Wauvel is $99 a month, everything included.
Can an AI CFO replace a fractional CFO?
For the recurring analysis — the monthly review, the cash forecast, answering questions from the books — often yes. For fundraising, lender negotiations, a sale of the business or any decision that needs someone accountable in the room, no. Those still need a person.
When should I hire a fractional CFO instead?
When a specific decision needs senior judgment and someone to stand behind the numbers: raising money, taking on significant debt, buying or selling a business, or a restructure. Many owners book a fractional CFO for that project and use software for the day-to-day.
Can I use an AI CFO and a fractional CFO together?
Yes, and it's often the cheapest way to get both. The software does the daily reads and the monthly review; the fractional CFO spends their billed hours on decisions instead of rebuilding the numbers.
How much does a fractional CFO cost?
Typically $150–400 an hour, and many work on a monthly retainer of $3,000 or more for a set number of days. The rate depends on experience, industry and how much of the work is strategic versus reporting.
