What a Fractional CFO Actually Does

A fractional CFO gives you senior finance leadership part-time: the strategy, the numbers behind the decisions, and oversight of the finance function — without the full-time cost. Here's what that looks like in practice, and the signs you've outgrown your bookkeeper.

A fractional CFO gives you senior finance leadership on a part-time basis. You get the strategy, the read on what the numbers are actually telling you, and oversight of how money moves through the business, without paying for a full-time hire. Most growing businesses reach a point where the bookkeeper keeps the records straight but nobody is steering. That gap is the job.

It is not bookkeeping, and it is not your year-end accountant. Both of those look backwards and keep you compliant. A CFO looks forward and helps you decide. The fractional part just means you buy a slice of that, sized to where you are now.

What a fractional CFO actually does

Day to day it tends to come down to a few things.

The first is making the numbers mean something. Plenty of founders have a profit figure and still cannot tell you which product, channel, or client is paying for the others. A CFO builds the view that answers that, then keeps it honest as the business changes.

The second is the decisions that ride on those numbers. Can we afford this hire. Should we take the bigger order that strains cash. What does the next round of pricing do to margin. These are not bookkeeping questions, and they rarely wait for the year-end.

The third is cash. A profitable business can still run out of money, and the warning usually shows up in a forecast weeks before it shows up in the bank. Keeping a rolling view of cash is one of the most useful things a part-time CFO brings, because it is the thing founders most often find out too late.

The last is oversight. Someone senior checking that the controls hold, the reporting is right, and the finance function is set up to scale rather than quietly breaking under more volume.

How is that different from a bookkeeper or an accountant?

Think of it as three different jobs that often get bundled into one word.

Your bookkeeper records what happened: invoices, bills, reconciliations, payroll. Your accountant takes that and files it: statutory accounts, tax returns, compliance. Both are essential, and a good fractional CFO works alongside them rather than replacing them.

The CFO sits a level up. The question stops being "is this recorded correctly" and becomes "what should we do about it." That is the line. If your finance conversations are all about the past, you have bookkeeping and compliance covered but no one is doing the CFO work.

When do you actually need one?

A few signs tend to show up together.

You are making bigger decisions on gut feel because pulling the numbers takes too long. Revenue is growing but you are not sure the growth is profitable. Cash feels tight in a way you cannot quite explain. You are heading into a raise, a loan, or a board that expects proper reporting. Or you simply notice that the finance side has become reactive, and every month closes a little later than the last.

None of these need a six-figure full-time CFO. They need a few days a month from someone who has done the job before — the signs you're at that point tend to cluster.

What does it cost, roughly?

Far less than a full-time hire, which is the whole point. A full-time CFO in Australia or the UK is a senior salary plus on-costs — here's how the numbers actually compare. A fractional arrangement is usually a monthly retainer scaled to how much support you need, so you get the seniority without carrying the fixed cost while you are still growing into it.

The honest test is whether the work pays for itself. Better decisions, cash protected before it became a problem, and time you get back are usually worth more than the fee. If they are not, you probably do not need one yet.

How we work

At GME we run it simply. Each month we review your P&L and balance sheet and set the strategy that follows. You get a scheduled call to talk it through, and unlimited access in between for the decisions that cannot wait until the next one. We handle the strategy and the oversight, not the day-to-day bookkeeping. If you need a bookkeeper, we will point you to a good one who works directly with you.

What makes our version a little different is that we build as well as advise. When the answer to a finance problem is a better report, an automation, or a tool that takes work off your team, we can build that too rather than handing you a recommendation and leaving.
