аудиторские услуги

We are proud to be the first audit firm to have audited the accounts of a Russian company to International Standards on Auditing in 1991. Since then we have been one of the leading audit companies on the market. We have been working in Russia for more than 30 years and have established a reputation as a professional audit firm that provides services in various industries.

To have impact, you need to focus on your core mission - and that's not financial statements, taxes, HR and payroll, billing, receivables, reconciliations or changes in legislation. When the question is how to manage it all - and at a decent level of quality - the answer may be to hand over some of these functions.

The world doesn't stand still and businesses constantly need to adapt to changing conditions. Market conditions are constantly dictating new challenges and not all businesses are able to adapt quickly to ongoing transformations. Analyzing the current situation, finding new solutions to optimize and improve business processes is a time-consuming, but very important task.

Large and medium-sized businesses, a first-time entrepreneur and already promoted start-up - all of them at least once have faced the need for competent legal advice. The maintenance of a large administrative apparatus, which includes good and specialized lawyers, is a very expensive solution.

We understand that each client is unique, both in terms of needs and under certain circumstances. We do not take a 'one-size-fits-all' approach. You can be assured that our advice will be tailored to your specific situation and according to your individual needs, and not just drafted from a template.

Every successful individual has specific needs and objectives for financial planning and asset management, which are influenced by many factors. There are ideas, needs and objectives in the area of private interest: from tax returns to international structuring and planning to accumulation and protection of private capital.
