Everything You Need to Know
General:
What solutions does Advintek offer for Greece e-invoicing?
Advintek provides a comprehensive, end-to-end e-invoicing solution specifically custom-built for the Greek market. Our platform automates invoice creation, performs real-time validation, handles electronic data transmission, and manages secure storage in full alignment with local tax mandates.
What is the current B2B e-invoicing mandate timeline in Greece?
Compliance is being rolled out in two critical phases in 2026. Phase A became mandatory on March 2, 2026, for businesses with a turnover exceeding €1 million. Phase B extends this mandate to all remaining taxpayers in Greece starting October 1, 2026.
What are the key business benefits of adopting Advintek’s system?
Beyond statutory tax compliance, Advintek accelerates your billing cycles, reduces administrative overhead, eliminates manual data entry errors, enables faster VAT refunds, and provides real-time visibility into your business’s financial health.
What types of integrations does Advintek support?
Advintek seamlessly integrates with leading ERP platforms (such as SAP, Oracle, Microsoft Dynamics, Infor SunSystems), localized accounting software, and custom legacy systems via secure APIs, ensuring no disruption to your daily operations.
Do you provide training and ongoing customer support?
Yes, Advintek offers complete onboarding training for your team along with dedicated 24/7 technical support. We assist you through the entire transition process—from initial AADE setup and testing to live production.
Technical:
Does Advintek’s solution natively support the myDATA platform?
Absolutely! Our system is fully integrated with the AADE myDATA (My Digital Accounting and Tax Application) platform. It automatically uploads all required invoice summaries, expense classifications, and transactional data without requiring manual portal entries.
What technical invoice formats does the platform support?
The platform automatically generates and processes invoices in the mandatory structured XML format compliant with the European standard EN 16931 and the specific Greek Core Invoice Usage Specifications (CIUS).
How secure is the data transmission process?
Data transmission is highly secure. We utilize advanced encryption protocols (SSL/TLS) and authenticated AADE API keys or Certified e-Invoicing Service Providers (ΥΠΑΗΕΣ) to guarantee that your corporate financial data remains completely confidential and tamper-proof.
Can Advintek’s platform handle high invoice volumes?
Yes, our platform is built on a highly scalable, cloud-based infrastructure capable of processing thousands of invoice transactions simultaneously, ensuring near-instant validation and minimal latency even during peak billing periods.
What is the typical implementation timeline for the Advintek system?
For standard configurations, integration can be completed within a few weeks. For complex enterprise ERP setups, our dedicated technical team works closely with you to ensure a swift, seamless deployment well ahead of the legal deadlines.
Compliance:
Is the system fully compliant with Greece's latest tax regulations?
Yes, Advintek is fully updated and compliant with Law 5222/2025 and the operational rules set by the Independent Authority for Public Revenue (AADE). It guarantees that every invoice issued meets the strict legal standards required by Greek tax authorities.
Can the system assist with audit readiness?
Yes. Advintek automatically cross-references and validates each transaction, maintaining a transparent, unalterable digital audit trail. This ensures your business is always fully prepared for any digital audits or tax verifications conducted by the AADE.
Will this system support ongoing regulation updates?
Definitely. As a cloud-managed solution, Advintek automatically deploys system updates whenever the AADE modifies its myDATA technical specifications, schemas, or Greek tax laws, ensuring your business stays compliant without any manual intervention.
Additional FAQ's:
How are the unique MARK identifier and QR codes handled?
Upon successful transmission, Advintek instantly retrieves the official registration number (MARK) from myDATA and dynamically embeds both the MARK and the mandatory QR code onto the visual invoice layout for immediate verification.
Does the system support cross-border (international) transactions?
Yes. While domestic B2B transactions are cleared through myDATA, Advintek also expertly manages international B2B invoices (imports/exports), ensuring appropriate VAT classification and reporting for EU (VIES) and non-EU trade.
What types of reports and dashboards are available?
The platform offers real-time dashboards and comprehensive reporting modules. You can track transmission statuses (Success, Pending, Failed), monitor your VAT liabilities, and easily reconcile your internal accounting books with the records visible on the official myDATA portal.
