Somewhere between “my accountant does the year-end” and “we hired a full-time CFO” lies a zone where most growing SMEs get stuck. The bookkeeping gets done, the tax returns get filed — but nobody is steering the finances. Nobody owns the cash flow forecast, challenges the pricing, or tells you which customers actually make you money.
That gap is exactly what fractional CFO support fills: senior finance leadership, a few days a month, at a fraction of a full-time cost.
What a fractional CFO actually does
“Fractional” simply means part-time and flexible — you get a chief financial officer’s skill set without the chief financial officer’s salary. The work typically covers:
The monthly rhythm
- Monthly finance review: closing review, KPI pack, and a working session on what the numbers mean
- Cash flow management: a rolling 13-week cash forecast, updated and discussed — the single most valuable habit for any SME
- Budget vs actual: where you’re off plan, why, and what to do about it
The forward-looking work
- Budgeting and forecasting: a realistic annual budget and rolling reforecasts as reality unfolds
- Profitability analysis: margins by product, service and customer — the analysis that changes pricing decisions
- Decision support: hiring plans, investment cases, make-or-buy questions, pricing changes — modelled before you commit
The structural work
- Reporting and dashboards: management information that’s actually used (often a CFO dashboard)
- Finance process improvement: faster closes, better controls, less manual work
- Banking and financing support: preparing the numbers story for lenders or investors
What a fractional CFO is not: a bookkeeper. The day-to-day processing still needs to happen — by your team, your bookkeeper, or a dedicated finance support service. The CFO works one level up.
Seven signals your business is ready
- You make significant decisions on gut feeling because the numbers arrive too late or you don’t fully trust them.
- Cash surprises you. Profitable on paper, yet the bank balance keeps getting tight — and you can’t see more than a few weeks ahead.
- Revenue grew but profit didn’t. Somewhere between turnover and the bottom line, money is leaking, and nobody has time to find out where.
- Your accountant answers questions but doesn’t ask them. Compliance is covered; challenge and strategy are not. (That’s not a criticism — it’s a different role.)
- A bank or investor asked for projections and producing them was painful.
- You’re scaling: new market, new entity, bigger team — and the finance function hasn’t scaled with you.
- Finance lives in your head. You’re the only one who understands the money side, and it’s consuming evenings.
Two or more of these, and a structured conversation about finance leadership will almost certainly pay for itself.
Practical example: a 12-person software company we support had grown to €1.4M revenue with the founder doing “CFO work” on Sunday nights. Within the first quarter of fractional support: a 13-week cash forecast (which moved a planned hire three months later and avoided a credit-line draw), customer profitability analysis (one “good” client turned out to be break-even after support costs), and a monthly KPI rhythm the management team now runs in 45 minutes.
When you don’t need one yet
Honesty matters here. Fractional CFO support is probably premature if:
- Your books aren’t reliable yet. Strategy on top of messy data is decoration. Fix the bookkeeping first — a cleanup plus monthly support is the right spend.
- You’re very early stage with simple finances and short cash visibility needs — a good accountant and a simple cash spreadsheet may genuinely be enough.
- You want someone to “do the admin”. That’s dedicated finance support, a different (and less expensive) service.
A trustworthy provider will tell you which one you need — and it isn’t always the bigger engagement.
What it costs, and how engagements work
Most fractional CFO arrangements run as a monthly retainer scaled to intensity — from a focused monthly review up to several days per month for businesses in active growth or fundraising. Compare that to a full-time CFO salary in the Netherlands and the logic is clear: you pay for the leadership hours you need, not for presence.
Good engagements share a structure: a defined monthly deliverable set (close review, KPI pack, cash forecast, advisory session), clear response arrangements between sessions, and no long lock-in — the work should justify itself month by month.
Common mistakes when hiring fractional finance help
- Hiring strategy while the foundation is broken. Sequence matters: clean books → reliable reporting → strategic support.
- No defined deliverables. “Some senior help” becomes vague hours. Agree the monthly rhythm up front.
- Confusing roles. Bookkeeper, controller, CFO — three levels. Be clear which gap you’re filling.
- Ignoring chemistry. This person will challenge your decisions. You need someone you’ll actually listen to.
Readiness checklist
- Books reconciled and closed monthly within a reasonable deadline
- A clear pain: cash visibility, profitability, growth decisions, or investor readiness
- Willingness to share full financial information and meet monthly
- A defined budget for finance leadership (separate from bookkeeping)
- Agreement on the first 90 days’ priorities

Frequently asked questions
What’s the difference between a fractional CFO and my accountant?
Your accountant primarily looks backward and outward: correct accounts, filed returns, compliance. A fractional CFO looks forward and inward: cash, margins, decisions, growth. Most businesses benefit from both — they’re complementary, not competing.
How many days per month is typical?
Anywhere from half a day to four days monthly. Most SMEs start around one to two days and adjust with the business cycle — more during budgeting or fundraising, less in steady state.
Can a fractional CFO work remotely?
Largely yes. Monthly reviews work well via video with screen-shared dashboards; periodic on-site sessions add value for team topics. We support clients across the Netherlands, Europe, the UK and the US this way.
Will they work with our existing bookkeeper and accountant?
They should — and good ones make both more effective: cleaner handoffs to the accountant, clearer priorities for the bookkeeper.
How quickly should we see value?
The cash flow forecast usually delivers insight in the first month. Profitability analysis and reporting improvements typically land within the first quarter. If you can’t point to concrete value after 90 days, change the scope or the provider.
