Frequently asked questions and answers
During the initial consultation, we will discuss your current situation, your challenges and your objectives – whether that is business succession, restructuring, a company check or strategic development. The consultation is non-binding and free of charge. Afterwards, you will receive an initial assessment and a transparent quote for further cooperation.
DeFORIS provides industry-independent advice to small and medium-sized enterprises with 10 to 400 employees – ranging from craft businesses to the manufacturing sector. Especially when you are facing strategic turning points: planning business succession, optimising structures, improving processes or needing to navigate through a crisis. We work with entrepreneurs who are looking for a peer-level sparring partner.
We support in four core areas: In business succession – when the handover is pending and fair solutions are required. In restructurings – when liquidity becomes tight or structures need to be adjusted. In the company health check – when you want to know objectively where your business stands. And in interim management – when important positions need to be filled temporarily.
DeFORIS has two locations – in Cologne (North Rhine-Westphalia) and in Wittlich (Rhineland-Palatinate). We advise clients throughout Germany. What matters is not the location, but the willingness to work together on solutions – whether on-site, hybrid or digitally.
DeFORIS combines practice-oriented expertise from various industries with a strong network of experienced consultants who have built up their knowledge across generations. Our approach: „From practice, for practice“ delivers solutions that can be applied directly in everyday business.

We develop ways and strategies that are actionable, effective and practice-oriented. Experience from various industries and generations creates orientation, clarity and confidence in business decision-making.
Companies choose DeFORIS because they are looking for clarity and reliability.
