The IAPR in Greece stands for Independent Authority for Public Revenue (Ανεξάρτητη Αρχή Δημοσίων Εσόδων). It is the government agency responsible for managing tax collection and overseeing the myDATA platform, Greece’s standardized electronic invoicing and bookkeeping system.The myDATA (My Digital Accounting and Tax Application) platform enables businesses to report invoices and accounting data in real time, ensuring compliance with Greek tax regulations. The system validates invoice data and assigns a unique identifier (MARK) to each transaction, automatically generating electronic accounting books.Invopop has partnered with ILYDA to issue invoices in Greece. Each supplier must be registered with ILYDA to issue invoices on their behalf. This involves authorizing ILYDA as an electronic invoicing provider in Taxisnet, declaring ILYDA as invoice issuer in myDATA, and signing a service provision agreement with ILYDA.
