+This chapter expands on the general terms and abbreviations described in the chapter ["Terminology"](../../general/terminology/terminology.md) of the General Part, with vocabulary specific to the Greek myDATA market.
+
+## The myDATA Ecosystem
+
+| **Term** | **Description** |
+| --- | --- |
+| AADE (ΑΑΔΕ) | The Independent Authority for Public Revenue — the Greek tax authority responsible for tax administration and operation of the myDATA platform. It publishes the technical specifications, reference tables, and compliance requirements used by businesses and software providers integrating with myDATA. |
+| myDATA | *my Digital Accounting and Tax Application.* AADE's platform that maintains the electronic books of Greek businesses. Businesses transmit invoice and receipt data to myDATA, which validates the submission, records it, and returns a unique registration number known as the MARK. Unlike Germany or Austria there is no local fiscal device involved — in Greece, fiscalization is an online API call to the tax authority. |
+| TaxisNet | The Greek government authentication service used by businesses and individuals for tax-related online services. For myDATA integrations, TaxisNet credentials are used to register for and obtain access to the myDATA REST API. |
+| aade-user-id / subscription key | The two credentials issued through the myDATA REST API portal. They are required to authenticate API requests and identify the integrating application when communicating with myDATA services. |
+
+## Identifiers myDATA Returns
+
+| **Term** | **Description** |
+| --- | --- |
+| MARK (Μοναδικός Αριθμός Καταχώρησης) | The unique registration number assigned by myDATA once a document is successfully submitted and accepted. The MARK is the official reference for the registered record, and every later action on that document (credit notes, delivery-note correlations, reporting) points back to it. |
+| UID (invoiceUid) | A unique identifier generated for a specific invoice or document within the myDATA ecosystem, used to uniquely identify the submitted document in technical integrations and data exchanges. |
+| Authentication Code | A verification value returned by myDATA for submitted documents. It allows third parties to validate that the document has been registered and stored by the tax authority. |
+| QR Code | Printed on the receipt; can be scanned to open or verify the corresponding digital document, giving customers and authorities a convenient way to access document information electronically. |
+| Unique Document Identifier (Μοναδικός αριθμός παραστατικού) | A human-readable identifier composed of several document attributes, in the format `AFM \| Date \| Branch \| Type \| Series \| Serial`. It makes it easier for users and authorities to recognize and reference a document without using technical IDs. |
+| Provider Signature | A cryptographic value generated by a certified service provider or fiscal mechanism, ensuring the integrity and authenticity of the document and proving that the data has not been altered after issuance. |
+
+## Document Types
+
+Every document reported to myDATA carries an `invoiceType` code. The codes are grouped into families:
+
+| **Family** | **Covers** |
+| --- | --- |
+| 1.x | Sales invoices for goods |
+| 2.x | Service invoices |
+| 5.x | Credit notes |
+| 6.x | Self-supply / own-use documents |
+| 8.x | Retail and POS-related documents |
+| 9.x | Transport and delivery documents |
+| 11.x | Retail receipts |
+
+The most commonly used types are described below.
+
+### 1.x — Invoices for Goods
+
+**1.1 Τιμολόγιο Πώλησης (Sales Invoice)** — A standard B2B invoice used for the sale of goods within Greece. *Example:* a wholesaler sells 100 bottles of wine to a restaurant and issues a sales invoice for the goods delivered.
+
+**1.2 Τιμολόγιο Πώλησης / Ενδοκοινοτικές Παραδόσεις (Intra-EU Sales Invoice)** — An invoice for the sale of goods to a customer located in another EU Member State. *Example:* a Greek company sells products to a company in Germany and issues an intra-EU sales invoice.
+

+
+### 5.x — Credit Notes
+
+Credit notes are used to reduce, reverse, or correct previously issued invoices.
+
+**5.1 Πιστωτικό Τιμολόγιο Συσχετιζόμενο (Correlated Credit Note)** — A credit note linked to a specific original invoice. *Example:* a customer returns damaged goods and the supplier issues a credit note referring to the original sales invoice.
+
+**5.2 Πιστωτικό Τιμολόγιο Μη Συσχετιζόμενο (Non-Correlated Credit Note)** — A credit note that is not directly linked to a single original invoice. *Example:* a supplier grants an annual volume discount covering many previous transactions.
+
+### 6.x — Self-Supply / Own Use
+
+**6.1 Στοιχείο Αυτοπαράδοσης (Self-Delivery / Own Use)** — A document used when business goods are withdrawn for internal consumption, personal use, or other non-sale purposes. *Example:* a restaurant owner uses inventory products for a private event rather than selling them.
+
+### 8.x — POS and Hospitality Documents

+
+**11.4 Πιστωτικό Στοιχείο Λιανικής (Retail Credit Receipt)** — A retail credit document used to reverse or reduce a previous retail sale. *Example:* a customer returns a product purchased in a store and receives a retail credit receipt.
+

+
+## Taxes Beyond VAT
+
+| **Term** | **Description** |
+| --- | --- |
+| Withholding Tax (Παρακράτηση Φόρου) | A tax amount withheld from a payment and remitted to the tax authority instead of being paid directly to the supplier or service provider. *Example:* a company pays a consultant €1,000 and withholds part of the payment as tax before paying the consultant. |
+| Fees (Τέλη) | Additional statutory charges reported separately from VAT and the net invoice value — for example accommodation-related fees or environmental/product-specific fees such as the plastic-bag fee. *Example:* a hotel issues an invoice that includes the accommodation charge plus the applicable climate-crisis-resilience fee. |
+| Stamp Duty (Χαρτόσημο) | A stamp-duty charge applied to certain transactions under Greek tax legislation, reported alongside VAT, withholding taxes, fees, and other taxes as a separate reference table. |
+| Other Taxes (Λοιποί Φόροι) | Tax amounts that do not belong to the VAT, withholding-tax, stamp-duty, or fee categories, reported under a dedicated "Other Taxes" table. |
+
+## Transport / Delivery
+
+The transport and delivery functionality in myDATA is primarily built around document type 9.3 (Δελτίο Αποστολής / Delivery Note) and its associated transport fields and reference tables.
+
+| **Term** | **Description** |
+| --- | --- |
+| Δελτίο Αποστολής (Delivery Note) | The document used to accompany goods while they are being transported. It records the movement of goods between locations and forms part of the transport documentation reported through myDATA. *Example:* a warehouse ships 50 cases of beverages to a retail store and issues a Delivery Note listing the goods being transported. |
+| Purpose of Movement (Σκοπός Διακίνησης / movePurpose) | Identifies the reason goods are being transported (e.g. delivery, return, transfer between own locations), classified via myDATA's Purpose of Movement reference table. *Example:* a company transfers inventory from its central warehouse to a branch office and reports the corresponding movement purpose. |
+| Transport Details | The information describing how and when goods are moved: dispatch date and time, vehicle number, loading location, and delivery destination. These support traceability during transport. *Example:* a distributor ships products from Athens to Thessaloniki; the Delivery Note records the dispatch time, truck registration number, loading address, and delivery address. |
+| Digital Shipping Note (DSN) Lifecycle | AADE's newer framework for digitally reporting and tracking goods movements, extending the traditional delivery-note process with a multi-party flow (issuer, carrier, recipient) for transport and logistics scenarios. It is documented separately from the core ERP specification and currently exists in two versions: **v2.0.1** (official) and **v2.0.2** (pre-official). *Example:* a manufacturer, a logistics provider, and the receiving customer each participate in a single goods movement, which is tracked and reported throughout the transport process. |
