Who this suits
Leinonen OÜ (established 1992) provides accounting, payroll, management reporting, taxation and legal services plus company registration, from Tallinn, and states ISO 9001 and ISO 27001 certification. Its three-decade Baltic/Nordic track record and information-security certification suit an established company that wants dependable, audited-quality bookkeeping rather than a bare-minimum service.
Ordinary accounting is not licensed in Estonia, so certifications and track record are the signal here; for any statutory audit you would separately need a sworn auditor.
