Beyond the Fractional CFO

Fractional executives are having a moment. The Financial Times recently highlighted their rise, with CFO roles now the largest category of fractional executive postings. The appeal is obvious: growing businesses can access experienced leadership without committing to another permanent C-suite hire. We think finance can go further. Bringing an experienced CFO in for a day or two a week may add valuable judgement at the top, but it does not by itself build the finance function underneath them. The systems, reporting, controls, technology, forecasting and day-to-day financial discipline that keep leaders close to the numbers are where we think much of the real value can be created.

In brief

A growing company does not need to start by asking whether it needs a fractional CFO.

It should start by asking whether its finance function is fit for where the business is going.

Most companies already have parts of finance covered. There may be a bookkeeper, accountant, tax adviser, payroll provider or company secretary. Those services matter.

The bigger question is whether the pieces join together into something management can actually use.

Can leadership see what is happening in the business? Is cash understood? Are forecasts current? Are margins visible? Can assumptions be challenged? Are the systems capable of scaling with the company?

A good finance function should answer those questions without forcing the business to build a large internal department before it needs one.

The fractional CFO solves only part of the problem

The rise of the fractional CFO makes sense.

Many companies need experienced financial judgement well before there is enough work to justify a full-time CFO.

The problem is not the fractional model itself. Ordinal can effectively provide that capability too.

The problem is treating the CFO as the starting point.

Senior financial judgement only works properly when the information underneath it is reliable.

Someone still needs to make sure the books close, cash is understood, reporting works, systems are connected, forecasts remain current and management has access to the information it needs.

A CFO reviewing the numbers once a week cannot compensate for a finance function that is poorly constructed underneath.

The opportunity is therefore bigger than accessing a senior executive for part of the week.

It is building the function itself.

The company needs the function before it needs the department

A growing company may need excellent finance long before it needs a finance team sitting inside the business.

That distinction matters.

Building internally takes time. Senior recruitment can stretch across months once sourcing, interviews, notice periods and reference checks are considered.

Then come recruitment fees, compensation, potentially equity, onboarding, systems access and the inevitable period while a new hire learns the company.

And if the hire is wrong, much of that process begins again.

None of that means businesses should avoid hiring.

At sufficient scale, strong internal finance leadership becomes essential.

But companies should not have to take on all of that cost, commitment and execution risk simply because they need better finance today.

An external team can provide the capability from the outset while the business builds permanent infrastructure only when the workload genuinely warrants it.

Technology changes what a finance function can look like

This is also no longer just a people question.

Finance technology has changed materially.

Invoicing, collections, payments, reconciliation, reporting, KPI tracking and cash visibility can increasingly be automated or connected through better systems.

That creates operating leverage.

A company should not necessarily need another finance hire every time revenue grows, invoice volumes increase or management asks for better information.

The right technology can allow more activity to flow through the finance function without headcount increasing at the same rate.

More importantly, it can change who has access to financial information.

A commercial or technical founder does not need to become an accountant. But they should be able to open a dashboard and understand how revenue, cash, margins, spend and other critical metrics are developing.

They should know when something is improving.

They should know when it is deteriorating.

And they should have some understanding of why.

That is a very different experience from discovering at month-end that performance was not quite what everyone thought it was.

Good finance infrastructure should make the whole leadership team more financially fluent.

Let operators operate

The role of finance is not to run the business for management.

It is to make the consequences of decisions visible.

If management decides to hire ahead of growth, increase customer acquisition spending or invest heavily in a new product, finance should help establish what the expected outcome is, what the decision means for cash and what success should look like.

Then it should measure what actually happened.

Did revenue develop as expected? Did margins improve? Did the investment generate the expected return? Did cash convert as anticipated?

Finance provides the numbers, challenge, context and evidence.

Management decides what to do with them.

That relationship works particularly well when finance is close enough to understand the business, but focused enough to remain objective.

An external team does not need to sit in every product stand-up or sales meeting to understand what matters.

Its job is to understand the business well enough to turn operating activity into financial information that leadership can use.

Build finance for where the company is going

A good finance function should not only deal with what happened last month.

As the company grows, the questions become more strategic.

How much capital should we raise? When should we raise it? Should the next stage of growth be funded through equity or debt? How much dilution is acceptable? Which investments are actually producing returns? What does the board need to see?

Later there may be international expansion, acquisitions, secondary transactions or a sale of the company.

Those moments place much greater demands on finance.

But the best time to prepare for them is not when the transaction begins.

The same systems, reporting discipline, controls and financial understanding that make a company easier to run also make it easier to finance, diligence and transact.

That is why we see finance setup, operations, strategic finance and transactions as part of the same continuum rather than separate services.

Build the team when the business needs the team

Eventually, the economics change.

The company becomes larger. The workload becomes more specialised and more continuous. A CFO role that once required one or two days a week becomes a full-time responsibility, and then considerably more than that.

Controllers, FP&A, treasury, tax and other specialist roles begin to justify themselves.

At that point, a strong internal finance organisation makes sense.

The objective is not to avoid building it.

It is to avoid building it before the business needs it.

Until then, there is no reason a growing company should not have access to the same disciplines, systems and senior judgement without carrying all of the permanent infrastructure.

What growing companies actually need

Fractional CFOs solve a genuine problem: companies need senior financial capability earlier than they need a full-time senior finance hire.

We think the opportunity is broader.

Growing companies often need the whole finance function earlier than they need the whole finance department.

That means reliable financial operations underneath experienced oversight. Technology that removes unnecessary manual work. Numbers that stand up to scrutiny. Forecasts that reflect the plan. Cash that is understood. Management information that gives leaders confidence in what is happening across the business.

And when the company eventually raises capital, borrows, acquires or sells, those same foundations should already be there.

Great businesses tend to have great finance functions.

The question is not whether that function needs to sit inside the company from day one.

The question is how best to build it.

Frequently asked questions

What is a fractional CFO?

A fractional CFO is an experienced finance leader who works with a company on a part-time or flexible basis rather than as a full-time employee. They typically support areas such as forecasting, board reporting, fundraising, capital allocation and financial strategy.

When does a growing company need a CFO?

A company often needs CFO-level capability before it needs a full-time CFO. That requirement tends to increase as forecasting becomes more important, boards or investors require better information, and financing or capital allocation decisions become more complex.

What is the difference between a fractional CFO and an outsourced finance function?

A fractional CFO generally describes senior finance leadership delivered on a part-time basis. An outsourced finance function can cover the wider requirement, including bookkeeping, reporting, cash management, forecasting, finance systems, technology and CFO-level support.

When should a company make its first finance hire?

There is no fixed revenue or funding threshold. A permanent hire becomes more compelling when the workload is sufficiently continuous, substantial and company-specific that bringing the capability in-house is more efficient than accessing it externally.

Can technology reduce the size of the finance team a company needs?

Yes. Modern finance systems can automate significant parts of invoicing, collections, payments, reconciliation, reporting and KPI tracking. That allows companies to process more activity and produce better information without increasing finance headcount at the same rate.

Can an outsourced finance function support fundraising or transactions?

Yes. A well-built finance function should make raising capital (debt and/or equity), acquisitions and other transactions easier because the underlying reporting, forecasts, financial records and supporting information are already organised and understood. We build data rooms for operational excellence that also do the heavy lifting with investors.
