Three labels, one job
The three terms grew up in different markets. Fractional CFO came out of the United States, where fractional executives (CFO, CMO, CTO) are a recognised category and the word signals a share of a senior person's week. Virtual CFO took hold in Australia and the UK as cloud accounting made it possible to run a finance function without being in the building. Outsourced CFO is the plainest of the three and tends to be used by accounting firms describing a service line rather than a person.
In practice the labels overlap completely. A firm offering virtual CFO services will happily be called a fractional CFO by a client who learned the term from a US podcast. The thing to notice is what the provider does not say: how many hours, from whom, and what the deliverable is.
What the job actually is
A tax accountant looks backwards once a year to get the return right. A CFO, in any of the three flavours, looks forward every month. The job has four parts and a provider that is missing one is selling something else under the name.
| Part of the job | What it looks like each month |
|---|---|
| Close the month | Bank, debtors, creditors, payroll, GST and loan accounts reconciled within a set number of days of month end, so the numbers are real before anyone reads them |
| Report | A management pack: profit and loss against budget, balance sheet, cash position, debtors and creditors ageing, and a short KPI set agreed with the owner |
| Forecast | A rolling 12-month cash flow forecast updated for actuals, so the question "can we afford this" has an answer before the decision, not after |
| Advise | A meeting to go through the pack and the decisions in front of the business, and someone to call between meetings when a pricing, hiring or lender question cannot wait |
Everything else, lender packs, board reporting, due diligence support, pricing reviews, hangs off those four. If the month is not closed, the pack is fiction; if there is no forecast, the advice is guesswork.
What the labels hide: who does the work
This is the real difference between providers, and none of the three labels tells you. There are three common models.
The sole practitioner. One experienced finance person, often a former corporate CFO, selling a day or two a week to a handful of clients. Strong in the meeting, but the close and the pack are either done by that person at a CFO's hourly rate or handed back to your bookkeeper, which is where timing slips.
The accounting firm. A chartered accountant leads the engagement and a team behind them does the close and the report build. The pack is reliable and on time because it is a production process, and the tax, compliance and lending work sits in the same place. The question to ask is whether the lead CA is actually in your monthly meeting or only signing the pack.
The software-plus-dashboard provider. Xero connected to a reporting tool, a templated pack and a quarterly call. Cheap, and fine for a business that mostly wants the numbers presented well. Thin when a decision needs judgement.
At National Accounts, Jonathan Perre, Chartered Accountant, leads every virtual CFO engagement, runs the monthly meeting and signs off every pack. A dedicated team of three does the close and the report build under his review, within seven days of month end. The fee is fixed monthly and quoted after a first meeting on your numbers.
When a full-time CFO is the right answer
A part-time CFO stops being enough when the finance function needs managing every day: a finance team of several people, multiple entities with intercompany flows, external investors who want board-grade reporting monthly, debt covenants that need active management, or an acquisition programme. At that point the business needs someone in the building, and the cost of a full-time CFO is justified by the complexity.
Before that point, most owner-managed businesses get the same decisions made for a fraction of the cost, because the work that matters (the close, the forecast, the monthly conversation) does not need a full-time seat. The honest test is whether a decision in the last six months would have gone differently with current numbers in front of you. If yes, you need the function. Whether it is full-time is a question of scale.
How to compare providers
Ignore the label and ask six questions. Who leads the engagement, and are they a qualified accountant? Who does the monthly close, and by what day? What is in the pack, and can I see a sample? Is there a rolling forecast, and how often is it updated? Is the fee fixed, and what changes it? And what happens when I call on a Tuesday with a lender question?
Then ask what the provider will not do. A good one will tell you that if the books are a quarter behind you have a bookkeeping problem first, and that a business simple enough to run on its BAS does not need a CFO at all. The ones who say yes to everything are selling hours, not judgement.

What is a fractional CFO?
A chief financial officer engaged for a fraction of a full-time role, usually a set number of days or a fixed monthly scope. The term is American; in Australia the same service is more often called a virtual or outsourced CFO.
Is a virtual CFO the same as an outsourced CFO?
Yes. Both describe senior financial leadership provided by an external person or firm rather than an employee. The labels say nothing about who does the work or what is delivered, which is what you should ask about.
What does an outsourced CFO do?
Closes the month, produces the management report pack and the cash flow forecast, meets with the owner to go through decisions, and handles finance questions between meetings: pricing, hiring, lenders and the tax position.
When does a business need a CFO?
When decisions are being made without current numbers, when cash surprises the owner, when a lender or investor wants proper reporting, or when a big move is coming. If the bookkeeping is behind, fix that first.
