Outsource – Concentrate on core business


Focusing on the core business is important when operating in foreign markets. A very typical decision that companies make, regardless of the industry, is to outsource accounting and all related administrative work to a reliable partner. For a majority of international companies, this is simply a natural part of a successful and effective business.  

Outsourcing accounting services is not only popular due to its cost efficiency but also because of the better results and quality it guarantees. Moreover, having a trustworthy accountant is one of most valuable assets a company that requires full control and security over its business operations can have. 

Cooperating with us on your accountancy needs prevents you from making mistakes in accountancy related issues and allows you therefore to concentrate on your core business. We are always abreast of developments in the industry and working with us thus saves you time and energy.   

The benefits of outsourcing accounting are for example:
  • Uninterrupted accounting 365 days per year
  • No employee sick leaves, holidays or maternity breaks.
  • Top quality services at reasonable price
  • Up-to-date understanding of local bureaucracy and business law
  • Financially valuable information available on demand
  • Reports and Financial Statements on time
  • Possibility to concentrate on developing other areas of successful business

Accountants and advisors at your service


The problems expanding businesses experience in new markets are often related to cultural and business administration differences between countries. Although the common regulations in the European Union make the business environment in our service region more stable, the accounting standards, laws, rules and best management practices still vary greatly.      

All Leinonen offices are adapted to local business conditions and possess the latest knowledge of the industry. Our managers and accountants are familiar with a number of business cultures, international accounting standards and the local legislation, and are therefore able to help customers solve their problems.
