Exceptional Value

Smart Investment

– Without the Overhead

We deliver high-impact, expert-led services at 
a better price point than major firms.
Here’s why:

No unnecessary expenses

No luxury office spaces, expensive license fees, or inflated managerial layers.

Lean and focus

We drive hybrid cars, not high-end fleets. We invest in knowledge, not in prestige.

Senior professionals, powered by smart automation

We've streamlined what can be automated, so our senior team spends less time on admin and more time delivering real insight.

Ethical and human-centric approach

We use AI to enhance human judgement, not replace it. Always in line with strict ethical and data protocols.

Global reach and independent mindset

We’re not part of an international chain - and we don’t need to be. Let our track record speak for itself.

Tamás Szekeres

Managing Director

As the Managing Director of an IT service company, it is especially important for me that our audit partner is technologically compatible with our systems and can guarantee robust data security. The Microsoft Azure Virtual Desktop and Microsoft 365 environment used by De Rossi Consulting is fully aligned with our infrastructure – making our collaboration not only efficient, but also secure.

What Our Clients Say

Throughout my professional career, I have had the opportunity to work with all four of the Big Four audit firms, which has provided me with extensive experience in collaborating with service providers at the forefront of the industry. For this reason, it is of particular significance to me that De Rossi Kft.’s professional standards measure up to the highest benchmarks in every respect. Our cooperation has proven not only to be reliable and precise, but also effective and forward-looking thanks to their innovative approaches.

Adrienn Vasvári

Head of finance Viador Átrium Group

As a Group consolidation director in international automotive group requiring high degree in flexibility, but where the quality of audit work is still non-negotiable, I appreciate De Rossi team for their focus on quality of work, but still able to find practicle soluation. They exceeded my expectation comparing them with previous auditor from Big4.

Vojtěch Karban

Group consolidation and tax director AURES Holdings a.s.

The De Rossi team’s professional competence and technological sensitivity ensure that our data is not only compliant with international standards, but truly secure. I chose them because they don’t just understand the technological requirements of a modern, security-conscious company – they actively apply them.

Tamás Szekeres

Managing Director InnoSol Informatikai Kft.

Everyone at De Rossi is professional, helpful, and cooperative. We’ve built an honest, trusting, and friendly relationship where we feel comfortable sharing even our most complex challenges – and always find effective, joint solutions.

Katalin Fábián

Company Manager Tuxera Hungary Kft.

When working with an audit team, what matters most is the ability to trust their expertise and precision. The team at De Rossi Consulting, led by Éva De Rossi, has exceeded all our expectations. Their regulatory knowledge is outstanding – not only in domestic matters but also in international standards, which is a major advantage in more complex projects.

Klára Patkósné Alter

Financial director P-Development Kft.

Our cooperation with De Rossi is very pleasant. They always provide us with timely services and offer professional suggestions when dealing with international differences. I think it is natural to continue to cooperate with them.

Their expertise is wide-ranging, enabling them to handle any challenge with confidence. De Rossi Consulting is characterized by exceptional speed and accuracy, making full use of modern technology.

Klára Patkósné Alter

Financial director P-Development Kft.

We can rely on the De Rossi team not only during the annual audit but throughout the entire year, whether we have accounting, reporting, or tax-related questions. They actively support us even in areas beyond traditional audit scope – like transfer pricing or complex tax matters – always with clarity, speed, and willingness to help.

Katalin Fábián

Company Manager Tuxera Hungary Kft.

The Microsoft Azure Virtual Desktop and Microsoft 365 environment used by De Rossi Consulting is fully aligned with our infrastructure – making our collaboration not only efficient, but also secure. Using the same digital platforms allows for encrypted, closed data management, audit-trail-ready processes, and smooth digital communication.

Tamás Szekeres

Managing Director InnoSol Informatikai Kft.

Communication is always open, clear, and highly efficient, and thanks to their flexibility, they easily adapt to changing needs. This team is more than just a service provider – they are a true partner. Working with them is not only effective, but genuinely enjoyable.

Klára Patkósné Alter

Financial director P-Development Kft.

I especially appreciated that when our previous auditor unexpectedly ceased operations, Éva and her team stepped in immediately – right in the middle of the financial year – and took over the engagement smoothly, ensuring continuity and a seamless transition. Since then, we’ve successfully closed five business years together.

Since then, we’ve successfully closed five business years together.

Their audit work is precise, reliable, and consistently meets the highest professional standards. They provided valuable support in critical periods such as a change in ownership combined with a financial year change, and later, during a switch in accounting firms – always demonstrating maximum flexibility and a stable professional presence.

The De Rossi team was recommended to me by a highly credible professional whose judgment I fully trust. From the outset, there was no doubt about their reliability or the standard of their expertise. Following our initial meeting, we received a well-founded and transparent proposal – tailored to the complexity of our international corporate structure and the specific nature of our operations involving intricate agreements.
