Mainstay is one of the leading audit, consulting and outsourcing companies. We have been operating in Russia for more than 30 years and currently have 3 offices - in Moscow, Vladivostok and Yuzhno-Sakhalinsk. Being a part of international network of Moore Global for a long time, we had a unique opportunity to share our practical experience and knowledge with our colleagues from all over the world. However, in March 2022 the company left the international network in order to protect its clients and since January 12, 2023 officially changed its name from MOORE ST to Mainstay. Today Mainstay is an independent group of companies with 100% Russian participation. Our clients benefit from years of experience and the highest level of advice, regardless of where they do business. Mainstay employees understand our clients' needs and help them win new markets, provide answers to their most complex questions, and solve various challenges they face.
