Industry specific expertise allows us to reach required quality levels. Moreover, cooperating with companies from different industries gives valuable business insights that we can utilize in future challenges.

International companies

Leinonen Group is specialized in serving international companies. Through our wide and unique international office and partner network, we are truly able to support companies in their internationalization processes. Meeting and maintaining high international requirements is extremely important for us. An essential part and the core of our business activities are the Finnish roots which creates an understanding of Western business values and business practices. This lays the foundations for reliable and fruitful cooperation with international clients. To enhance the Nordic tradition the majority of Leinonen management has either a Finnish or Nordic background.

Entering a new business environment is never easy, but well-planned and supported business operations are much more likely to succeed. We are able to work within tight schedules, follow industry standards and communicate in multiple foreign languages in addition to the local language.

Local companies

Local clients are typically served by the local Leinonen office, which provides the client all the necessary help and resources for quality accounting, administration and payroll management. In addition, a client is advised in various business issues, such as internationalization or local legislation. Meetings and close collaboration are a necessary part of any successful relationship.

Adapting our services to client’s individual needs is essential for any company, but especially so for small and middle-sized companies, who appreciate the flexibility of administration. Local companies also value our trustworthiness and international experience.
Leinonen supports and takes care of its clients' finances and thus helps them, for instance, to overcome the challenges and risks related to the starting up of a new business and avoid difficulties when outsourcing accounting.
