How to read the ranking
Why can familiar accounting brands look different in this ranking?
The ranking measures legal entities rather than marketing brands or consolidated groups. Separate entities within one group can therefore occupy separate rows, while a familiar accounting brand can sit outside the strict list when its current main industry is not 69201.
Services and main industry are not always identical
The current PRH main industry for Talenom Oyj, Greenstep Oy, and Rantalainen Oy Botnia is 70200. They therefore sit outside this strict 69201 ranking even though they provide accounting services.
Group figures are not mixed with standalone entities
Administer Oyj and Aallon Group Oyj are ranked using legal-entity revenue. Consolidated group revenue is not compared with standalone revenue for other entities.

Methodology
How was the top-30 accounting-firm ranking built?
The ranking is a static snapshot dated August 30, 2026. It combines the active DM Faster Finland company projection, current official PRH identities and main industries, and company-level public financial observations.
1. Defining the market
The candidate population contains 3,944 active Finnish entities whose current PRH main industry was 69201, accounting, bookkeeping, and tax consultancy.
2. PRH identity verification
The largest candidates were matched to their current official name, Business ID, register status, and main industry in PRH Open Data.
3. Financial observation
Each published entity received its latest comparable legal-entity revenue observation from DM Faster company data. Fiscal year and personnel remain visible row by row.
4. Manual quality control
Classification errors, ambiguous administrative entities, and candidates focused on other activities were removed. The remaining legal entities were sorted by revenue and the largest 30 were published.
Limitations you should read
- This is a reviewed snapshot from DM Faster company data, not an official Statistics Finland, PRH, or accounting-industry market census.
- The candidate population is limited to active Finnish entities whose current PRH main industry is 69201. A current main industry can differ from a company's best-known service or previous classification.
- The industry-code population contained clear mechanical false positives from accommodation, catering, and energy. These were removed during manual review.
- The ranking covers legal entities. Separate entities belonging to one brand or group can appear on separate rows, and their revenue is not combined at brand or group level.
- Talenom Oyj, Greenstep Oy, and Rantalainen Oy Botnia are outside the strict list because their current PRH main industry is 70200, even though they provide accounting services.
- The latest comparable revenue observations cover fiscal years 2024 and 2025. The year is shown row by row and the figures should not be read as same-calendar-year market shares.
- Two ranked entities have no personnel figure in the source used. The employee total covers 28 entities.
- Revenue measures legal-entity size, not service quality, profitability, customer satisfaction, or suitability for a particular client.
- Public financial data and main industries change. Rankings can move after a new filing, merger, demerger, or classification update.
