FAQ

An answer to all your accountancy questions

What does accountancy cover?
What does accountancy cover?
Accountancy is a broad field. The main objective of accountants is to support and unburden their clients by preparing financial reports, identifying financial risks, managing bookkeeping, and providing services such as tax advice, legal guidance, and investment recommendations. They stay up to date with the latest legal standards and regulations to ensure your business remains fully compliant.
When should you consult an accountant?
Do all businesses need an accountant?
What is the difference between a bookkeeper and an accountant?
What is the difference between a bookkeeper and an accountant?
A bookkeeper primarily focuses on recording financial data and transactions, while an accountant takes on a broader role by analyzing financial statements, offering tax advice, and developing financial strategies. However, the terms “bookkeeper” and “accountant” are increasingly used interchangeably today. The title accountant is actually reserved for bookkeepers who have passed rigorous exams and obtained certification from the ITAA (Institute for Tax Advisors and Accountants).
What should you expect to pay for a bookkeeper?
What should you expect to pay for a bookkeeper?
What may seem like a cheap solution at first can quickly turn into an expensive mistake. Unfortunately, there are bookkeepers who aren’t strict about deadlines, are overworked, don’t make time for their clients, or simply lack the necessary expertise. That can lead to late or incorrect tax filings — which in turn can result in fines that run into the thousands of euros. Luckily, that’s not the norm.

A bookkeeper who files everything correctly and on time, while also offering you personal and proactive advice tailored to your situation, does come at a cost. But the right advice — like switching from a sole proprietorship to a limited company to reduce your tax burden — can easily pay for itself.

Bottom line: cheap rarely means good, but expensive doesn’t always mean better either. Always choose quality — in the long run, it will likely bring the highest return. And above all, don’t see working with an accountant as a cost, but rather as an investment.
