How I Work

Digital & flexible

I work fully digitally and efficiently using secure online tools. This allows me to respond quickly, adapt flexibly to your questions, and remain directly and easily accessible. Because I work independently and do not have high fixed costs such as staff or a large office, I can offer professional accounting services at attractive and transparent rates, with direct and personal guidance.

Experience & expertise

I have extensive experience in Belgian and international accounting. Thanks to my thorough knowledge of local legislation and tax regulations, I can provide accurate, practical and up-to-date advice, even in more complex situations.

Self-employed professionals & SMEs

I understand the needs of self-employed professionals and small businesses. My approach is personal, pragmatic and tailored to your reality and stage of growth.

Modern technology

I use the latest digital accounting systems and automate processes wherever possible. This results in less administration, fewer errors and faster insight into your figures.
