Accountor Group

Accountor traces its origins to Pretax, an accounting firm founded in Finland in 1986 by Asko Schrey. In 2000, Pretax merged with Konekirjanpito, another Finnish accounting company. This merger created the largest accounting firm in Finland at the time, with 350 employees.

As Pretax grew, it expanded beyond Finland through a series of acquisitions and partnerships in the Nordic countries and elsewhere in Europe. This internationalization phase began in the late 1990s and early 2000s, and Pretax progressively established a presence in Norway, Sweden, Denmark, the Netherlands, Russia, and Ukraine, and expanded to ultimately serving companies of all sizes, from SMEs to multinational corporations.

In 2013, Pretax adopted the unified "Accountor" brand, consolidating more than a hundred acquired local companies under a single identity.

In July 2024, Aspia Group acquired Accountor's outsourcing business, integrating it into its accounting, payroll, tax and advisory services operations. Following the transaction, the outsourcing operations became part of Aspia but continued to operate under the Accountor brand.

Following the acquisition of the outsourcing business, the software business operated temporarily as Accountor Software before being rebranded as Finago. KKR acquired a majority stake in the software business from Vitruvian Partners in July 2024.

In 2026, the Accountor outsourcing business was rebranded as Aspia in Finland in February, Norway in March and Denmark in May. The Accountor brand continues to be used in the Netherlands and Ukraine.
