What Audit Advisory OÜ does

Audit Advisory OÜ is a privately-held Estonian professional services firm that provides statutory auditing, accounting, financial consulting, and HR management services to businesses operating in Estonia. The firm operates through two legal entities: Audit Advisory OÜ (Reg. No. 11556099), which holds Licence No. 96 for statutory audits under the Estonian Auditors Activities Act, and Accounting Advisory OÜ (Reg. No. 12236647), which delivers day-to-day bookkeeping, payroll, tax declarations, and annual reporting services. The firm is led by sworn auditor Liina Tamm and supported by a small team of certified professionals including an audit project manager, chief accountant, and specialized accountants.

The company's service portfolio spans core audit engagements (statutory audits, reviews, internal audits, project audits, packaging report audits, and other assurance services) and comprehensive accounting services (daily bookkeeping, tax declarations, annual reports, financial analysis, payroll, and HR administration). It supports multiple accounting software platforms including Directo (primary), Merit, Merit Palk, and Simplbooks, adapting to client technology preferences. The firm is a member of PrimeGlobal Network, one of the world's leading associations of accounting and advisory firms, providing access to international resources for cross-border engagements. It serves Estonian businesses across multiple sectors, delivering services in Estonian, Russian, and English.

The firm's business model is built on direct, sales-led client engagement, with quote-based pricing and multi-year contracts. Clients request quotes via phone or email by submitting company documentation. Revenue is generated entirely through professional services fees across three streams: audit services, accounting services, and financial consulting. The firm operates from a single office in Haabneeme, Viimsi, Estonia, with a workforce of 1-10 employees. Distribution relies on direct contact, website inquiries, LinkedIn presence, and referrals from law firm partnerships. The firm has earned regional credibility recognition including Äripäev TOP Platinum 2025 and Trustworthy Company 2026.
