Our Audit Services

We deliver financial statement audits for organizations with both domestic and global operations. These audits allow our clients to meet their investor and/or regulatory reporting requirements within today’s dynamic business environment.

Grant Thornton Greece, as a firm of Chartered Accountants and Management Consultants, provides Special Tax Audit Services for the issuance of the Tax Compliance Report (Tax Certificate) in accordance with Article 65A of Law 4174/2013, as currently in force. The tax audit applies to public limited companies (S.A.), limited liability companies (L.L.C.), and branches of foreign companies.

Our IPO service helps prepare your business for the public offering process by addressing key areas such as framing the market opportunity and equity story, modelling financial track records, identifying business risks, and outlining expected growth drivers. We assess historical financial information, strengthen your internal control environment, and develop risk frameworks. Our services also cover corporate and tax structuring, reviews of cyber security measures, and the establishment of a potential corporate governance framework, ensuring a comprehensive approach to your IPO journey.

SOC Reports are external, independent attestations that provide assurance to customers and regulators. 

Internal Control Assessments are broader and focus on the organization’s risk management and compliance posture.

Value:

  • Builds trust with clients.
  • Identifies gaps in processes before they become audit findings.
  • Strengthens compliance with laws.

Agreed Upon Procedures (AUP) engagements offer a flexible and focused alternative to traditional audits, providing independent insights on specific areas of interest. At Grant Thornton Greece, we work with you to define tailored procedures that address your unique needs — whether it's verifying transactions, assessing internal processes, or reviewing compliance matters — delivering clear, reliable findings without the need for a full assurance opinion.

An assurance engagement where the practitioner concludes that nothing has come to their attention to suggest the information is materially misstated.
