Controller & CFOWhat Does a Fractional CFO Actually Do All Month?

Owners who hire a fractional CFO sometimes have a quiet worry around week two: "I haven't heard from them. Are they doing anything?" It's the same feeling as wondering whether the dishwasher actually ran.

The answer, when the engagement is set up well, is yes. Most of the work happens between meetings, and a good CFO makes it visible. This article walks through a typical month so you know what fractional CFO work looks like, what you should receive, and where your time fits in.

If you're still at the "what is this role, exactly?" stage, our explainer on what a fractional CFO is and isn't is the better starting point.

What does a fractional CFO do in week one?

Week one usually starts with cash. Before the prior month's books are even closed, the CFO updates the rolling cash forecast with last week's actual receipts and payments, then looks forward.

Many CFOs use a 13-week cash flow forecast for this, because it's short enough to be accurate and long enough to see trouble coming. If you haven't seen one, our guide to the 13-week cash flow forecast explains how it's built.

Typical week-one outputs: an updated forecast, a short note on anything unusual (a big customer paying late, an expense arriving early), and a heads-up if a cash dip is coming.

Week two: reviewing the close

Once your bookkeeping and controller team closes the prior month, the CFO reviews the financial statements. They're looking for meaning, not typos (the controller handles accuracy).

That means comparing results to budget and to the same month last year, then asking why. Revenue is up 12%: is it price, volume or one large project? Gross margin dropped two points: materials, labor or job mix? Overhead jumped: a one-time cost or a new habit?

This is where a budget earns its keep. If the difference between a budget and a forecast is fuzzy for you, our piece on budgeting and forecasting separates them.

Week three: the planning meeting

This is the meeting you'll see on your calendar. It usually runs 60 to 90 minutes and covers:

1. Last month's results in plain English, with the two or three things that matter
2. The cash outlook for the next quarter
3. KPIs (the handful of numbers you've agreed to watch, like gross margin, days to collect receivables or revenue per employee)
4. Decisions on the table and what the numbers say about each
5. Action items, with owners and dates

A good meeting ends with fewer open questions than it started with. A great one ends with you knowing exactly what to do before the next one.

Week four: models, projects and the in-between

The rest of the month goes to whatever the business needs. Common examples: modeling a new hire, testing a price change, preparing a loan renewal package, planning inventory for a busy season, or building scenarios for a second location.

Ad hoc questions land here too. "Can we afford to give raises in January?" deserves a real answer within a few days, not a shrug until the next meeting.

A worked example: one month at a 15-person agency

Here is a made-up case. You run a 15-person marketing agency with about $2.8 million in annual revenue. Here's how a month might go:

• Week one: The CFO updates the 13-week forecast and spots that two retainer clients worth $38,000 a month combined have contracts ending in eight weeks. Cash looks fine now and tight in week ten if neither renews.
• Week two: The close shows gross margin fell from 52% to 47%. The review finds freelancers covered a capacity crunch on one large project, at a higher cost than staff.
• Week three: In the planning meeting, you decide to start renewal conversations now, hold off on a planned hire until at least one renewal is signed, and adjust pricing on the project type that keeps needing freelancers.
• Week four: The CFO models two scenarios for the hire (now vs after renewal) and sends a one-page summary showing the cash low point under each.

That's roughly 15 to 20 hours of work, and almost none of it happened in the meeting itself.

The benefits of a fractional CFO, in practical terms

The main benefit is decisions made earlier, with numbers attached. Instead of finding out about a cash dip when it arrives, you see it weeks ahead. Instead of debating a hire on gut feel, you see its effect on cash and margin.

There's also a quieter benefit: you stop being the only person thinking about finance at 11 p.m.

How CFO advisory fits with the rest of the team

A CFO's month depends on the close arriving on time and being right. That's why ABFI's CFO advisory services sit on top of a fractional accounting department: bookkeeping, controller oversight and the monthly close, with a Client Accounting Manager coordinating the handoffs so the CFO's week two isn't spent waiting on week one.
