Personal accounting services.

From international public companies to domestic micro businesses, the requirements of administrative services comprise the same basic principles: predictability, standardization and flexibility. With decades of experience in serving international and domestic, large and small customers alike, we retain those principles as our mission.

We differentiate ourselves from large accounting houses by the level of personal support we offer clients. This is achieved by key account managing, where all clients are appointed a primary contact directly supported by a partner. This structure applies to everything we do.

Jasecon has grown organically, with dedicated long-term personnel whose focus is providing quality services and satisfaction in a convivial partnership with clients. The main languages in which we offer service are English, Estonian, Finnish, German and Italian. Our membership in an international accounting network allows us to provide truly international services accompanied by a traditional family business feel.
