Leinonen Group

Leinonen Group is an internationally established accounting, payroll, tax, and legal services firm with strong Finnish roots. Founded in Finland 37 years ago, the company has grown into a group of over 270 employees working across 11 countries, including Poland, Hungary, Bulgaria and Ukraine in Central Europe.

Finnish Values, International Reach

Leinonen was established in Finland, and that heritage still shapes how the company works today: reliability, transparency, and a straightforward way of doing business. Many Finns work across Leinonen country offices, helping to carry these values into every market the group serves, from the Baltics and the Nordics to Central Europe, Ukraine, and Kazakhstan.

Supporting Foreign Companies in Poland, Hungary, Bulgaria and Ukraine

In the Central Region, Leinonen works mainly with foreign-owned companies entering or already operating in Poland, Hungary, Bulgaria and Ukraine. For businesses unfamiliar with local regulations, this can mean the difference between a smooth market entry and a costly misstep.

Leinonen core offering in the region centers on accounting and payroll, complemented by company registration, tax advisory, management reporting, and legal support. Each local team combines knowledge of country-specific rules with the practical experience of handling cross-border matters, so clients can trust that their books are accurate and their obligations are met, wherever they are based.

A key advantage for international clients: all Leinonen staff communicate in English. There is no language barrier between the client and their accountant, and no need to rely on translated documents or third-party interpreters. Combined with a single group standard for quality and reporting, this makes it straightforward for a Finnish, or any foreign, company to manage its finance function across several countries through one trusted partner.

Why It Matters for Kauppayhdistys Members

For companies considering Poland, Hungary, Bulgaria and Ukraine as their next market, having a local partner who understands both the regulatory landscape and the needs of a foreign owner is invaluable. Leinonen presence across the Central Region, backed by 37 years of group experience and a genuinely Finnish way of working, offers exactly that kind of support.
