Rantalainen provides accurate and accessible bookkeeping at all times. In addition to standard bookkeeping services, we provide required notifications such as VAT, TyEL and YEL insurances to Finnish authorities.

Bookkeeping must be accurate. A primary concern is the availability of information to both the company and its various stakeholders. Assessment of a company’s profitability and operations is based on the information generated by accounting, making it a cornerstone of business operations. Rantalainen’s accessible accounting services enable company owners, partners, and the authorities to optimise outcomes by making effective decisions at the most appropriate times.

We tailor our accounting services to perfectly match your needs, with reference to your field and level of expertise. We are proud to serve all kinds of enterprises from self-employed entrepreneurs to globally expanding growth companies.
