ATNEO is a Team of experienced tax advisers, lawyers and experts specializing in integrated, highly specialized customs, tax and legal advice.

We initially analyze the issue and provide the Clientw with our offer in the form of a draft written contract.

After its acceptance by the Client – we proceed to work according to the previously agreed rules.

To maintain the highest quality of services – the results of our work, before their transfer to the Client, are the subject of our double verification and internal control.

For Clients interested in our constant support – we offer favorable variants of permanent cooperation agreements

Our consultancy is specialized and individual in nature. Our services are always priced individually – depending on the complexity of the case and the scope of the estimated involvement of our specialists.

In cases where the Client has a dispute with customs and tax authorities, it is also possible to partially determine our remuneration based on the “success bonus” formula.

For Clients interested in constant ongoing support, we offer preferential options for the pricing of our services as part of a predetermined package of hours to be used.

Each project is carried out with the participation and supervision of an ATNEO expert with appropriate qualifications – a Tax Advisor.

Most often it is also a person who has direct contact with the Client.

Less complicated design works that do not require the involvement of a Tax Advisor – also people with less experience (ATNEO consultants) are involved.

In order to maintain the highest quality of our services, ATNEO Partners are involved in all key aspects of our consulting, as well as at the Client’s request, who supervise the services provided in terms of content and organization
