Hellenic Auditing

What Hellenic Auditing does

Hellenic Auditing Company S.A. (Ελληνική Ελεγκτική AE, trading as Kreston Greece and HAC SA) is a Greek professional services firm founded in June 2010 and headquartered in Marousi, Athens, with additional offices in Thessaloniki and Rethymno. The firm provides three core service lines: audit and assurance services, tax advisory and compliance services, and general business consulting/advisory services. It serves corporate clients—primarily financial and general directors of Greek companies—requiring statutory audits, tax filings, and business process optimization, and positions itself as supporting multinational and large Greek enterprises that need independent financial oversight.

The firm operates on a traditional professional services revenue model: fees are negotiated per engagement, with no publicly disclosed pricing. It maintains ISO 9001 (Quality Management), ISO 27001 (Information Security), and ISO 37001 (Anti-Bribery Management) certifications, and is a member firm of the Kreston Global international accounting and advisory network (operating as "Kreston Greece"). Its technology stack is conventional for a professional services firm—no proprietary software, APIs, or AI products are disclosed; service delivery depends on certified statutory auditors, tax consultants, financial advisors, and business consultants with prior experience in multinational organizations and established Greek audit firms.

Distribution is direct-to-client, with no intermediaries; the firm supplements outreach through content marketing (Greek-language website publishing frequent tax, accounting, labor, insurance, and audit legislation updates). The firm is privately held under the Greek Anonymos Etairia (S.A.) legal form, with no public listing, no disclosed shareholders, no subsidiaries, and no recorded M&A, funding, or restructuring events. Revenue, headcount specifics beyond the 51–100 employee range, and management team composition are not publicly disclosed.
