Accountant vs Financial Controller vs CFO: What Irish Founders Actually Need

Updated 11 October 2026

By Richie Lennon

An accountant, financial controller and CFO cover different finance responsibilities. Accounting includes records, accounts and tax compliance. A controller keeps the finance operation and reporting reliable. A CFO brings financial leadership to decisions such as funding, expansion and investment. These responsibilities overlap. Choose the work your business needs, not a title or turnover rule, and make sure someone owns delivery.

An owner tells us they need a CFO because their accountant is not giving them enough support. Often the immediate problem is simpler: the books are late, margins are unclear and nobody is translating the numbers into a decision.

You may need better monthly reporting before you need a senior finance hire. You may also need specialist advice for a particular decision while the bookkeeping is being improved. The work does not fall into three sealed boxes.

Start with what you cannot answer today. Then decide who needs to answer it and how often.

The difference between the three roles

The distinction is responsibility and depth, not that accountants only look backwards or controllers cannot forecast. A capable accountant can deliver management reporting and advice. A controller can own budgets and cash forecasts. A CFO still needs sound accounting underneath the strategy.

Check the engagement. A job title does not tell you what is included, who does it or when it will arrive.

What do you need the finance function to do?

Write down the decisions coming up over the next six months. Hiring, buying stock, taking a lease, borrowing or entering a new market all need different information.

Do not pay for a strategy conversation that keeps returning to missing purchase invoices. Equally, do not postpone a material decision until every historical coding issue has been fixed. Agree what can be made reliable now and what uncertainty remains.

Monthly control: the work owners often need first

A useful monthly finance process closes the books, checks the balances, explains the result and identifies the actions.

The balance sheet matters as much as the profit and loss. Bank accounts, payment-provider clearing accounts, stock, debtors, creditors and tax balances need to be supportable. A profit report built on unreconciled records can send you in the wrong direction.

Then connect profit to cash. An invoice can improve profit before the customer pays. Buying stock can use cash before that stock becomes an expense. A tax payment can reduce cash without being a cost of that same month.

Our management accounts service is the relevant starting point when the gap is reliable reporting and a conversation about what it means. Confirm the agreed scope and timetable rather than assuming every accounts-preparation engagement includes this work.

Remove the paperwork bottleneck

Richie’s finance-function argument starts with three sources: sales, bank transactions and purchase invoices. The first two can have good automated feeds while the third still depends on the owner finding documents.

Supplier emails, subscriptions and staff card receipts need a collection process. A missing invoice is not a problem a board presentation can solve. Give that process an owner, an accessible submission route and a clear exceptions list. Our Dext workflow guide explains how document collection fits into the monthly close.

Automation helps the collection and recording. Someone still needs to check the result and resolve the questions that prevent a clean close.

When does CFO input become useful?

CFO work is useful when the decision needs more than a report of the current position. You may need to compare options, challenge assumptions, plan funding or explain the financial consequences to a board or investor.

For a proposed hire, the question is not only whether last month was profitable. What is the cash cost of employment? When will the extra capacity generate revenue? What happens if the sales arrive three months later than planned? Our business forecasting guide explains how to test those assumptions.

For expansion, the model may need new-market costs, stock commitments, tax and currency considerations. For an acquisition, it may need diligence and specialist legal and tax advice as well as the operating forecast.

Turnover alone does not answer this. A smaller business with a funding event can need focused senior input. A larger, stable business may have a strong controller and require occasional specialist support rather than a full-time CFO.

Which numbers matter in your sector?

Choose measures that connect to decisions. Use consistent definitions, not every metric your software offers.

For an agency, a busy team does not prove a profitable project. For ecommerce, ad-platform revenue does not prove contribution. For SaaS, a cash runway estimate needs a clear definition of burn and a realistic receipts forecast.

Do not import a sector benchmark as a universal pass mark. Define the number, compare it consistently and decide what you will do when it changes.

A decision model should show the downside

Suppose a business has €80,000 available cash and expects €20,000 of net cash generation over the next three months before a new commitment. A project needs €60,000 up front.

Both scenarios can look viable at the end of the period. The timing within those three months could still create a shortfall. Check the weeks when wages, tax and supplier payments fall due, and agree the minimum cash buffer the business needs.

This is an illustration, not a client result. It shows the job: expose the assumption that matters before you commit.

In-house, outsourced or a combination?

This article helps identify the work. How you resource it is the next decision.

An employee can provide daily access and know the operation closely. An external team can supply several skills without every role being a full-time hire. A combination can work when an internal finance person owns the daily process and outside specialists provide accounts, tax or senior advice.

Compare the complete scope, coverage and accountability. Who handles leave? Who checks the work? Who maintains the forecast? Who attends the decision meeting? Who is responsible when the underlying records are late?

Do not compare one salary with a service fee unless the responsibilities are equivalent. Software, recruitment, employer costs, cover and specialist work affect the comparison.

Ask for outcomes you can recognise

A useful scope says what will be delivered and how it will help you act. For example:

• A monthly close with outstanding issues clearly identified.
• A reporting pack with consistent margin and cash definitions.
• A forecast updated when material assumptions change.
• A meeting that ends with decisions, owners and dates.
• Specialist input for the transactions outside the routine engagement.

It should also state the information your business must supply. Clear responsibility works both ways.

If your Irish business turns over €250,000 or more and you cannot get the financial answers you need, book a Finance Fit Call. We can identify the gap and discuss the appropriate level of support, without starting with a job title.
