For more than 6 years I have been cooperating with Advizer and its CEO Leonid Viktorov in various legal areas, including advice on lease agreements, various legal issues and monitoring changes in legislation. I can recommend Leonid as a person who always treats his work with due responsibility and attention, always does everything promptly. For me, Advizer is a reliable and decent partner

We have been cooperating with Leonid since 2019. We have completely outsourced all the legal tasks of our business. Leonid helped us to optimize the structure and build legal processes. I would especially like to note the speed of responses, customer focus and understanding of the specifics of the business of IT companies, both in Ukraine and globally. I strongly recommend

Our acquaintance with the BIZ-ADVISER company took place back in 2017. Colleagues helped to determine the business model, to bring it to life, and since then they have been helping in work – advising on legal issues, keeping accounting records. We know about the latest changes in legislation, we are confident that the financial statements will be submitted without errors and on time. We often come to colleagues with a problem, for a consultation in the evening or on a weekend – they will listen and offer solutions. Thank you for your work, attention and care. We hope for continued cooperation, we wish BIZ-ADVISER development, growth, new customers.

We have been working with Leonid for a long time. As a Scandinavian IT company, it was important for us to build a completely safe and highly efficient environment within the framework of both the laws of Norway and Ukraine. Leonid has a wide range of knowledge, I have never been able to confuse him with my questions. He knows the situation well, quickly gets into the picture and has a range of practical solutions in stock that can be successfully applied right there. In general, I recommend
