Fractional CFO vs Full-Time CFO vs Accountant: How to Choose
A bookkeeper or accountant records and reports what happened. A full-time CFO owns the finance function and the financial strategy every day. A fractional CFO gives you CFO-level leadership for a set number of days each month. Choose by the decisions you need help with, not by job title: cash and funding decisions point to a CFO; compliance and recording point to an accountant.
Bookkeeper or accountant
- Records transactions, reconciles, prepares statutory accounts and tax filings
- Looks backward: what happened and what you owe
- Needed by every business; a CFO does not replace this role
Full-time CFO
- Owns finance strategy, funding, reporting, controls and the finance team every day
- Makes sense when the business is large or complex enough to keep a senior person busy, and the cost fits the plan
- Highest cost and commitment
Fractional CFO
- Senior financial leadership for a fixed number of days each month, on a monthly retainer or a fixed-fee project
- Typical work: 13-week cash forecast, monthly close, management pack, KPI dashboard, budget, lender or investor pack
- Fits startups that have outgrown bookkeeping but cannot yet justify a full-time CFO
Signs you need more than an accountant
- You find out about cash problems after they happen
- Decisions on hiring, stock, pricing or expansion are made on instinct
- Reports arrive late or nobody trusts them
- You are preparing for a bank facility, investor round or acquisition
How to decide
Write down the three decisions you struggle with most. If they are about cash, margin, funding or growth, you need CFO-level help. If they are about filings and records, you need an accountant first. Many businesses use both: the accountant keeps the books and the fractional CFO uses them.
Frequently asked questions

When should a startup move from fractional to full-time?When the finance workload and complexity keep a senior person busy most of the week and the cost fits the plan. A fractional CFO can help you assess that.
Does a fractional CFO replace my bookkeeper?No. They work alongside your bookkeeper and your registered tax agent.
