Interdisciplinary examination
At KONLUS, auditing encompasses more than just the performance of statutory and voluntary annual audits of individual and consolidated financial statements in accordance with HGB and IFRS.
Our mission is to provide our clients with comprehensive support within the limits permitted by law.
As auditors, our responsibility is to express an opinion on whether the financial statements are free from material misstatement. Through our work, we contribute to increasing the reliability of the information contained in the financial statements.
Further services
We also offer other services in the field of auditing:
- Through our subsidiary IT-AUDIT we are able to offer high-quality IT auditing and consulting services.
- Through our active membership in PrimeGlobalan award-winning network of independent auditing, tax consulting and management consulting firms, we are currently able to support our clients in 112 countries in cooperation with our colleagues there in the area of auditing.
Client-specific advice
Our employees have many years of experience in advising and auditing companies that prepare annual financial statements in accordance with HGB and IFRS. When supporting our clients, we ensure that the audit and service teams are put together according to the client's specific requirements.
In addition to documenting the key audit findings and results, our audit reports provide detailed and informative analyses that go far beyond the required scope. In this way, we support the company's supervisory bodies in particular and provide the basis for further assessments of the company.

Frequently asked questions
Would you like to work with us and commission us for your tax, business management or start-up projects?
Perhaps you would like to switch from another law firm to our services. We will give you a brief overview of the first steps here. You are also welcome to contact us directly and we will advise you personally about the possibilities in our offices in Bensberg and Cologne.
The first step is to contact us. Use our short, compact contact form to do this. Simply click on one of the buttons to go directly to the contact form - alternatively, you can also give us a call.
Once we have received your data, we will contact you promptly for a free and non-binding initial consultation.
We also inform the tax office on your behalf about the change of tax advisor.
n the initial consultation, we would like to be able to assess your current situation. You should therefore describe it to us at the initial meeting. On this basis, our tax law experts will develop a strategy with which we can support you individually. In this context, you will also receive the relevant information on our specific price offer.
If you are happy with our offer, you will be given a mandate - otherwise this initial consultation will be all that remains. There is therefore no risk for you.
You do not need any documents for our non-binding initial consultation. However, if you would like to talk about optimizing your tax situation right away, it would be useful if you could prepare the following documents:
- Last annual financial statements with supplementary documents (tax return)
- last income tax assessment
- Current BWA with proof of accounts
If you would like to switch from your previous tax advisor to KONLUS, they are obliged to transfer data, open contracts and any documents to us. We use software from the market leader DATEV, which makes the transfer easy in most cases.
As a rule, there are also no notice periods to observe - we will be happy to check this with you and take care of the other formalities regarding the change.
We also inform the tax office on your behalf about the change of tax advisor.
What is important to us is that we do not manage the past, but shape the future. In doing so, we seek direct proximity to our clients and always keep our eyes and ears open for optimization opportunities. We keep you informed proactively and on an ongoing basis.
What our ongoing service is not: thoughts of excessive time expenditure and price. Instead, we want to be the strong partner at your side who actively takes care of your ongoing processes. We point out possible optimizations and advise you professionally and individually.
