- myDATA
- my Digital Accounting and Tax Application
- myDATA is the electronic bookkeeping platform of the Greek tax authority (AADE). Every business in Greece must transmit the data of its issued and received documents to myDATA, where they form the business's electronic books. Transmission can be done directly through business software, through a certified e-invoicing provider, or manually on the AADE portal.
- AADE
- Independent Authority for Public Revenue (Ανεξάρτητη Αρχή Δημοσίων Εσόδων)
- AADE is the Greek independent tax authority. It operates the myDATA platform, licenses e-invoicing providers, and sets the technical specifications that invoicing software must follow.
- MARK
- Unique Registration Number (Μοναδικός Αριθμός Καταχώρησης)
- MARK is the unique registration number that myDATA returns for every document successfully transmitted to it. A document is considered registered in the electronic books only once it has received a MARK.
- E-invoicing
- Electronic invoicing, ηλεκτρονική τιμολόγηση
- E-invoicing is the issuing, sending and receiving of invoices in a structured electronic format that can be processed automatically. In Greece, e-invoicing in the formal sense is performed through a certified e-invoicing provider, which digitally stamps the document, transmits it to myDATA and delivers it to the recipient.
- E-invoicing provider
- Πάροχος ηλεκτρονικής τιμολόγησης
- An e-invoicing provider is a company licensed by AADE to issue electronic invoices on behalf of businesses. The provider applies the digital stamp, assigns the unique identifier, transmits the document to myDATA and delivers it to the recipient. eFluper connects to a certified provider (Impact), so documents issued in eFluper can be sent as formal electronic invoices.
- B2B
- Business to business
- B2B documents are invoices issued by one business to another. In the Greek e-invoicing context, B2B e-invoicing means sending those invoices to the recipient business through a certified provider rather than by plain email or on paper.
- B2G
- Business to government
- B2G documents are invoices issued to the Greek public sector. Suppliers to public bodies are required to send invoices electronically, through a certified e-invoicing provider, in the prescribed structured format.
- B2C
- Business to consumer
- B2C documents are retail receipts and invoices issued to private individuals. B2C e-invoicing covers issuing those documents electronically and transmitting them to myDATA, including retail sales receipts and service receipts.
- APY
- Απόδειξη Παροχής Υπηρεσιών, service receipt
- An APY is a receipt for services rendered, the document a freelancer or service business issues to a private customer. It is the most common document type for freelancers in Greece and must be transmitted to myDATA like any other document.
- ALP
- Απόδειξη Λιανικής Πώλησης, retail sales receipt
- An ALP is a receipt for the retail sale of goods to a private customer. Retail businesses issue it at the point of sale and transmit it to myDATA.
- Delivery note
- Δελτίο αποστολής
- A delivery note accompanies goods in transit and records what is being moved, from where and to where. It can be issued on its own or combined with an invoice as an invoice-delivery note.
- Self-invoicing
- Αυτοτιμολόγηση
- Self-invoicing is when the buyer issues the invoice on behalf of the supplier, under a prior agreement between them. The buyer is then responsible for transmitting the document to myDATA.
- Tax mechanism
- Φορολογικός μηχανισμός, EAFDSS
- A tax mechanism is the hardware device that was traditionally required to stamp retail documents in Greece. Businesses that issue documents through a certified e-invoicing provider do not need one, because the provider applies the digital stamp instead.
- POS integration
- Διασύνδεση με POS
- POS integration is the required link between a business's card payment terminal and its invoicing system, so that a card payment is matched to the document it pays for and reported consistently.
- VIES
- VAT Information Exchange System
- VIES is the European Commission system for validating the VAT numbers of businesses in other EU member states. It is used to confirm that an intra-EU customer is a registered business before invoicing without VAT.
- VAT number
- ΑΦΜ, Αριθμός Φορολογικού Μητρώου
- The AFM is the Greek tax identification number held by every business and individual taxpayer. It identifies the parties on every invoice and is the key used to look up a customer's registered details.
