FAQ's about Fractional CFO

What is a fractional CFO?

A fractional CFO is an experienced Chief Financial Officer who works with a company on a part-time, flexible basis - providing the same strategic finance leadership as a full-time CFO, without the full-time salary, contract, or overhead. The role covers financial planning, reporting, cash flow management, investor relations, and strategic decision support. The key difference is engagement model: a fractional CFO works across multiple clients simultaneously, allocating time according to what each business actually needs. For founder-led companies and scale-ups that need senior finance leadership but are not yet ready - or willing - to commit to a full-time hire, it is typically the most cost-effective and flexible option available.

What is the difference between a fractional CFO and a full-time CFO?

The work is largely the same. The commitment is not.

A full-time CFO is a permanent employee, typically costing £150,000–£300,000+ per year in salary alone, before benefits, pension, and notice periods. They are embedded in one company, full-time, indefinitely.

A fractional CFO provides clearly defined finance leadership at a fraction of that cost, with no long-term employment obligation. Engagement can be scaled up during critical periods — a fundraise, a restructuring, a transaction - and scaled back when the pressure eases.

Unlike an interim CFO position, which is typically a short-term mandate, a Fractional CFO's tenure can be unlimited. A Fractional CFO is committed for as long as needed.

At what stage does a company need a fractional CFO?

Earlier than most founders think - and later than most CFO firms will tell you.

The practical trigger is usually one of the following: the CEO is spending significant time on finance and admin tasks; reporting to investors or the board is slow, inconsistent, or stressful; financial decisions are being made on instinct rather than data; or the company is approaching a fundraise, acquisition, or significant growth phase.

Revenue is not the determining factor. We have worked with companies from €2M turnover with complex cross-border structures, and with larger businesses that simply had no financial hygiene in place. Stage, complexity, and leadership bandwidth matter more than size.

If the CEO is effectively acting as the CFO, that is usually signal enough.

How much does a fractional CFO cost?

The cost depends on the scope, seniority and engagement model. Typically, a fractional CFO charges a monthly retainer fee for a defined number of days per week.

Day rates for senior fractional CFOs generally depend on experience, sector and location.

Project-based engagements - such as supporting a fundraise or leading an investor process - are typically scoped and priced separately.

The relevant comparison is not "fractional CFO vs no CFO." It is "fractional CFO vs full-time CFO." A well-scoped fractional engagement provides strategic output at a fraction of the cost of hiring someone full-time.

What are the signs that the CEO is doing the CFO's job?

The most common sign is time: if the CEO is regularly involved in monthly close, preparing board packs, managing banking relationships, or fielding investor queries on financials, the finance function has effectively defaulted upwards.

Other indicators include: reporting that is consistently late or manually assembled in spreadsheets; cash flow surprises that should not be surprises; an inability to answer basic financial questions quickly without going back to the books; and strategic decisions - pricing, hiring, investment - being made without reliable financial modelling behind them.

None of these is a failure. They are symptoms of a company that has grown faster than its finance infrastructure. The problem is not the CEO's competence. It is the structure.

What is the difference between a fractional CFO and a controller or bookkeeper?

A bookkeeper records transactions. A controller ensures the numbers are accurate and compliant. A fractional CFO uses those numbers to drive decisions.

The distinction matters because they solve different problems. Poor cash flow management is not a bookkeeping problem. Weak investor reporting is not a controller problem. Strategic financial planning, scenario modelling, board-level communication, fundraising support, and business structuring sit firmly in CFO territory - regardless of whether that CFO is full-time or fractional.

Many companies try to solve a CFO problem by adding accounting resource. It rarely works.

Can I scale a fractional CFO up or down depending on what we need?

Yes - and this is one of the primary reasons companies choose the fractional model in the first place.

A typical engagement might start at one or two days per week, then increase during a fundraise or transaction, and reduce again once the acute pressure has passed. Some clients move from fractional to near full-time for a defined period and back again as circumstances change. Others maintain a consistent light-touch retainer for ongoing strategic oversight.

The engagement is structured around what the business needs at any given point, not around a fixed job description. That flexibility is not a compromise. For most growth-stage companies, it is the more rational model.

Can a fractional CFO lead a fundraising or investor process?

Yes. Investor readiness, fundraising preparation, and transaction support are core fractional CFO competencies - not add-ons.

In practice, this includes building or stress-testing financial models, preparing investor-facing materials, managing due diligence processes, and working alongside corporate finance advisors or investment banks during a formal process. A fractional CFO who has done this before brings process discipline and credibility that a first-time founder simply cannot replicate alone.

At Peak Consulting, we have led majority stake sales to private equity, coordinated multi-country investor processes, and supported companies through full exit transactions.

What happens when we no longer need a fractional CFO?

A well-structured engagement ends cleanly. That is the point.

When a company reaches the stage where a permanent, full-time CFO is the right hire - whether because of scale, complexity, or investor requirements - the fractional CFO's job is to hand over and step aside. That means documented processes, a stable finance function, and a clear brief for whoever comes next.

At Peak Consulting, we do not engineer dependency. If the business no longer needs us in the same capacity, we say so. We have ended engagements, scaled back to advisory retainers, and handed mandates to permanent hires on good terms. That is how it should work.
