Fractional CFO vs Chartered Accountant: what’s the difference?
Chartered accountant and CFO are complementary, not interchangeable. A comparison of their remits and scopes, and when each becomes essential.

Co-founder, fractional CFO and CFO

"I already have an accountant, so why would I need a CFO?" It is a common confusion. The chartered accountant and the CFO have complementary but entirely different jobs. Comparing a CFO with an accountant is like comparing a pilot with a mechanic — both are essential, but they do not do the same job.
The accountant: the guardian of compliance
Its role is accounting and tax:
- Records accounting operations (invoices, bank, payroll)
- Prepares tax declarations (VAT, IS, CET)
- Produces the annual accounts (balance sheet, income statement)
- Ensures regulatory compliance
- Responds to tax audits
Its horizon is retrospective: it deals with what happened. Average cost: €800-2,000/month.
The Fractional CFO: the performance driver
His role is financial management:
- Implements the financial strategy
- Builds financial models and forecasts
- Manages cash flow and monthly reporting
- Supports fundraising and M&A
- Optimises tax (CIR research tax credit, grants)
- Structures management control
- Leads reporting to the board
Its horizon is prospective. At Iter Advisors: €3,000–8,000 excluding tax/month, depending on scope and profile.
The winning duo: accountant + CFO
The accountant provides the accounting basis — the CFO uses this basis to manage.
