AI operations consultant vs fractional CFO

A fractional CFO gives a growing brand senior finance judgment part time: the plan, the capital, the lender, the board. An AI operations build gives the finance and operations team its time back by putting a model on the recurring reporting. They solve different problems and work well together: the CFO decides what the numbers should say, and the model produces them every week without the copying and pasting.

Side by side

  • A fractional CFO brings judgment on capital, the lender, the plan and the board; a senior voice in the room; and a few days a month of an experienced finance leader's time.
  • An AI operations build brings the recurring reporting done every week on your definitions: the close pack, the weekly recap, the board package, inventory reports. It is working software your team owns, and it does not need anyone's days to run.
  • Neither replaces the person on your team who knows the business. Both work better when that person's week is not spent copying exports.

When each one fits

Start with a fractional CFO when there is a raise coming, a lender to bring in, no plan, or no senior finance voice at the table.

Start with an AI build when the finance team is capable but buried, the reports arrive late, or the CFO you already have spends their days building packages instead of reading them.

Do both when a new investor arrives and wants better reporting at the same time as better judgment, which is common. A fractional CFO is often the best person to own the definitions an operations audit writes down.

Questions

Do we need a fractional CFO or an AI build?

If the gap is judgment, such as raising money, a lender relationship or a plan nobody trusts, hire the CFO. If the gap is capacity, with smart people spending their week rebuilding reports, start with the build. Many brands have both gaps.

Can AI replace a fractional CFO?

No. It replaces the assembly work that often falls on a fractional CFO's limited hours, so more of the hours you pay for go to judgment.

How do they work together?

The CFO sets the definitions and decides what the board package needs. The model is built on those definitions and produces the package, the close and the weekly numbers. The CFO reviews instead of builds.

How is the work priced?

Fractional CFOs usually bill a monthly retainer for a set number of days. AI operations work is priced as fixed fees per engagement, then an optional monthly partnership. See pricing.
