Going Beyond Quick Estimates: Why Our Due Diligence Sets the Foundation for Accurate Valuation
Determining the fair value of a business cannot be simplified through quick appraisals or basic calculators. Business valuation is a complex, multifaceted process that requires meticulous attention and appropriate expert knowledge.
Determining the fair value of a business cannot be simplified through quick appraisals or basic calculators. Business valuation is a complex, multifaceted process that requires meticulous attention and appropriate expert knowledge.
The process begins with a thorough due diligence conducted by our experienced auditors. We scrutinize the Company’s records, processes, and transactions to gain a comprehensive understanding of its current state – this forms the foundation of reliable business valuations.
This ensures a reliable business valuation outcome.
Following the in-depth work carried out by our auditors, our highly qualified business valuators take over to interpret this data within the framework of current market trends, future projections, and a myriad of other factors. Combining methodologies such as discounted cash flows, comparable company analysis, and asset valuation, we arrive at a realistic, defensible, and data-driven valuation of your business.
This professionally grounded and comprehensive approach ensures an assessment that truly reflects the enterprise’s value for stakeholders. It enables informed decisions to be made in mergers, acquisitions, strategic planning, or investor relations.
Based on the company valuation, you can effectively represent your own business interests – so you won't regret your decisions when it's too late.

During the due diligence, we assess financial and operational risks, evaluating the reliability of financial data and the sustainability of the business in question.
After thorough preliminary examination, we select the most suitable valuation methodology for the particular case—be it income, market, cost, or option-based. Each approach is refined to provide the most accurate depiction of the company’s value.
It’s crucial to recognize that valuation is not a fact but an opinion. Our documents reflect a nuanced perspective, considering various market factors, aiming to provide a thoughtful, understandable, and comprehensive picture of the company’s value.
We identify the primary factors that create or destroy value. If the evaluation is for a specific transaction, we assist in determining a target price and developing a negotiation strategy.
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.

They exceeded my expectation comparing them with previous auditor from Big4.

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