The Difference Between an Accountant and a Fractional FD/CFO

Introduction

For growing SMEs and construction firms, it’s easy to assume that an accountant and a fractional Finance Director (FD) or CFO are the same thing. After all, both deal with numbers and finances. But the reality is very different.

An accountant ensures compliance, while a fractional FD or CFO provides strategy. Knowing the difference is vital, because hiring one when you need the other can mean missed opportunities, poor cash flow management, and stalled growth.

At Jones Financial Accounts (JFA), we specialise in guiding business owners through this distinction and showing how the right financial expertise drives better results.

Clear Explanation

• Accountant: An accountant focuses on compliance and reporting. They make sure your books are correct, VAT returns are filed, payroll is processed, and annual accounts are submitted to HMRC and Companies House. Their role is essential for legal compliance and accurate financial records.

  
  

• Fractional FD/CFO: A fractional FD or CFO works at a higher level. Instead of just recording history, they help shape the future. They look at forecasts, budgets, cash flow, pricing models, funding, and growth strategy.

  
  

  “Fractional” simply means part-time, you get board-level expertise without paying a full-time salary.

Think of it this way: an accountant tells you what happened, a CFO helps decide what happens next.

Why It Matters for Businesses

Many SMEs stop at an accountant because they see finance as compliance. But in practice:

• With only an accountant: You’ll know your numbers are accurate and tax-compliant, but you won’t always see financial problems coming. For example, a construction company might file accounts showing profit, while in reality, delayed customer payments are creating a cash crisis.

  
  

• With a fractional FD/CFO: You get forward-looking insight. That same construction firm would have forecasts showing cash gaps months in advance, allowing them to renegotiate supplier terms or adjust project scheduling.

Impact if ignored: SMEs often face unnecessary funding rejections, uncontrolled overhead creep, or pricing errors. By the time the accountant’s year-end report shows the damage, it’s too late.

Benefit if done right: Businesses with CFO-level oversight typically achieve stronger margins, better cash flow discipline, and more successful growth because decisions are guided by data, not guesswork.

Strategy to Get It Right

1. Assess your needs:

   • If compliance and filing are your main issues, an accountant is sufficient.

   • If you’re scaling, seeking funding, or struggling with cash flow, you likely need a fractional FD/CFO.

   
   

2. Blend both roles: The best businesses use accountants and FDs together, accountants to ensure accuracy, FDs to provide strategy.

   
   

3. Start fractional: For firms around £500k–£5m turnover, a full-time CFO may be overkill. A fractional FD/CFO provides the expertise without the full-time cost.

   
   

4. Review regularly: As you grow, revisit whether part-time support should shift into a full-time strategic finance hire.

   
   
   
   
   
   

5. Common Mistakes (and the Consequences)

• Relying only on compliance: Business owners often think annual accounts = financial strategy. The result? Surprise tax bills, unexpected cash crunches, or weak profit margins.

• Hiring too late: Many firms bring in an FD only after banks decline funding. By then, reputational damage is done.

• Misusing accountants: Expecting your accountant to act like a CFO without giving them scope or resource means missed growth opportunities.

Consequences include HMRC penalties from poor forecasting, lost tenders due to weak financial presentation, and strained supplier relationships when cash issues go unplanned.

Misconceptions

• “I can’t afford a CFO.” A full-time CFO may be expensive, but a fractional FD/CFO is cost-effective, often less than the cost of a junior manager, while delivering board-level expertise.

  
  

• “My accountant already does this.” Not true. Most accountants handle compliance and historical data, not strategic planning, cash forecasting, or board reporting.

  
  

• “Only big companies need FDs.” False. SMEs benefit the most, especially construction firms with complex contracts, project costs, and cash flow cycles.
