# myDATA Comply > Shopify app that issues AADE myDATA-compliant retail receipts, delivery notes, and credit notes directly from the Shopify order page, through Novus Conceptus (a certified Greek Electronic Invoicing Provider) — no cash register or ERP required. Documentation is bilingual: Greek (`/el/`, default) and English (`/en/`). myDATA Comply is built for Greek Shopify merchants who must report retail sales to AADE (the Greek tax authority) in real time under the myDATA framework. It replaces a physical ταμειακή μηχανή (cash register) for e-commerce orders. ## Docs (English) - [Setup Guide](https://mydata-comply.gr/en/guides/setup/): Install and configure the app in a Shopify store. - [Activation](https://mydata-comply.gr/en/guides/activation/): How TaxisNet authorization completes after onboarding. - [Submitting Documents](https://mydata-comply.gr/en/guides/submitting-documents/): How receipts, delivery notes, and credit notes are submitted to myDATA. - [VAT & Pricing](https://mydata-comply.gr/en/guides/vat/): How VAT-inclusive/exclusive prices are handled and which rate applies. - [Cancellations](https://mydata-comply.gr/en/guides/cancellations/): How to cancel delivery notes and issue credit notes. - [Dashboard](https://mydata-comply.gr/en/guides/dashboard/): Tracking submissions, quota, and billing. - [PDF Generation](https://mydata-comply.gr/en/guides/pdf-generation/): Branded tax documents with QR codes. - [Plans & Pricing](https://mydata-comply.gr/en/guides/pricing/): Free trial and subscription plans. - [FAQ](https://mydata-comply.gr/en/guides/faq/): Common questions on activation, setup, billing, security, and support. - [Payment Methods](https://mydata-comply.gr/en/guides/payment-methods/): Payment method codes for myDATA submissions. - [Document Statuses](https://mydata-comply.gr/en/guides/statuses/): Meaning of each submission status. - [Changelog](https://mydata-comply.gr/en/guides/changelog/): Product updates. - [Privacy Policy](https://mydata-comply.gr/en/legal/privacy-policy/) - [Terms of Service](https://mydata-comply.gr/en/legal/terms-of-service/) ## Docs (Ελληνικά / Greek) - [Οδηγός Εγκατάστασης](https://mydata-comply.gr/el/guides/setup/): Εγκατάσταση και ρύθμιση της εφαρμογής στο Shopify. - [Ενεργοποίηση](https://mydata-comply.gr/el/guides/activation/): Εξουσιοδότηση μέσω TaxisNet. - [Υποβολή Παραστατικών](https://mydata-comply.gr/el/guides/submitting-documents/): Αποδείξεις, δελτία αποστολής, πιστωτικά. - [ΦΠΑ & Τιμολόγηση](https://mydata-comply.gr/el/guides/vat/): Χειρισμός τιμών με/χωρίς ΦΠΑ. - [Ακυρώσεις](https://mydata-comply.gr/el/guides/cancellations/): Ακύρωση δελτίων και έκδοση πιστωτικών. - [Πίνακας Ελέγχου](https://mydata-comply.gr/el/guides/dashboard/): Υποβολές, quota, χρεώσεις. - [Δημιουργία PDF](https://mydata-comply.gr/el/guides/pdf-generation/): Παραστατικά με QR codes. - [Πακέτα & Τιμολόγηση](https://mydata-comply.gr/el/guides/pricing/): Δωρεάν δοκιμή και συνδρομές. - [Συχνές Ερωτήσεις](https://mydata-comply.gr/el/guides/faq/): Ενεργοποίηση, ρύθμιση, χρεώσεις, ασφάλεια, υποστήριξη. - [Τρόποι Πληρωμής](https://mydata-comply.gr/el/guides/payment-methods/): Κωδικοί τρόπων πληρωμής. - [Καταστάσεις Παραστατικών](https://mydata-comply.gr/el/guides/statuses/): Σημασία κάθε κατάστασης. - [Αλλαγές](https://mydata-comply.gr/el/guides/changelog/): Ενημερώσεις προϊόντος. - [Πολιτική Απορρήτου](https://mydata-comply.gr/el/legal/privacy-policy/) - [Όροι Χρήσης](https://mydata-comply.gr/el/legal/terms-of-service/) ## Optional - [Sitemap](https://mydata-comply.gr/sitemap-index.xml) - Support: lefteris@weam.gr / +30 698 359 6733
