HLB Tietotili

What HLB Tietotili does

Tietotili Audit Oy (operating as HLB Tietotili / HLB Finland) is a PRH-registered Finnish auditing society headquartered in Vantaa, founded in 1985 with the audit practice established in 1994. The firm is led by co-founders Urpo Salo and Veikko Virkki and employs approximately 10 professionals holding KHT, HT, and KRT certifications — including KRT-accredited auditors authorized to provide CSRD sustainability assurance. Service lines center on statutory audit (Tilintarkastus) and extend to Due Diligence Review, Special Audit, Internal Audit, Assurance Engagements, Auditor Statements (transport permits, reorganisation opinions), Corporate Responsibility / ESG services, Advisory Services, and Legal and Tax Services.

Following the August 2024 divestiture of its accounting and payroll operations to Rantalainen Group via a share transaction, Tietotili Audit Oy has repositioned as an audit-only firm, retaining its name and ownership while separating from the prior accounting practice to eliminate auditor-client conflicts of interest. The firm serves SMEs, micro-enterprises, and family-owned companies (with turnover up to tens of millions of euros), Finnish subsidiaries of international groups, and companies subject to CSRD reporting — including documented long-tenured mandates such as CPC Finland (nine years, four group entities). International client work is delivered through the HLB International network, of which the firm has been a member since 1997, providing reciprocal referral access to 1,000+ member offices in 100+ countries.

Go-to-market is sales-led and relationship-driven: clients engage via a named assigned expert, an online contact form with quotation requests, and recurring free webinars on legal topics (operational since 2023). Pricing is not publicly disclosed; engagements are scoped through direct quotation. Marketing extends through the firm's website, social channels (LinkedIn, Instagram, Facebook), the HLB Insights newsletter, and HLB International events. Revenue model is fee-based professional services across audit, advisory, legal, and ESG assurance.

• Rantalainen GroupcoreStrategic or Co-development Partner · 21 August 2024In August 2024, HLB Tietotili Oy and its direct subsidiaries transferred their accounting services operations to Rantalainen Group via a share transaction. The accounting business continues under Rantalainen with existing staff in the same premises and on the same terms. Tietotili Audit Oy (the audit firm) continues independently. The transaction removes the conflict of interest that previously prevented Tietotili's owners from acting as auditors for their accounting clients.
