Setup Guide

Step 1: Install the App

Install myDATA Comply from the Shopify App Store. After installation, you’ll be redirected automatically to the onboarding wizard.

Step 2: Onboarding Wizard (3 minutes)

On first launch, the guided wizard walks you through 4 steps:

1. Welcome

A brief overview of the process — what you’ll need and what happens next.

2. Company Details

Fill in your company information:

Field	Description	Example
Επωνυμία (Legal Name)	Your registered business name	ΕΤΑΙΡΕΙΑ Α.Ε.
Διακριτικός Τίτλος (Short Name)	Trading name	Etaireia
ΑΦΜ (VAT Number)	Your 9-digit Greek VAT number	123456789
Διεύθυνση (Address)	Street and number	Ερμού 10
ΔΟΥ (Tax Office)	Your tax office	Α’ Αθηνών
Νόμιμος Εκπρόσωπος (Legal Rep.)	Full name	Giorgos Papadopoulos
ΑΦΜ Διαχειριστή (Admin VAT)	Admin VAT ID	987654321
Email	Business contact email	info@company.gr
Τηλέφωνο (Phone)	Business phone	+30 210 1234567
Τύπος Υπηρεσίας (Service Type)	B2B / B2C / Both	Both

Tip

Choose the correct Service Type — it determines the contract terms and which fields are required for B2C retail receipts (11.1).

B2C: Alternative Communication Provider

If you select B2C (or Both), the wizard also asks for an alternative communication provider number. This is the backup channel declared for your retail receipts, and it has one strict requirement:

• It must be a line from a Greek telecommunications provider — Cosmote, Vodafone, Nova and similar.
• The line must be registered to the same ΑΦΜ as the business that signs the provider agreement.
• In other words: the telecom contract for that number is in the company’s name, not in a personal name.

Caution

A personal or prepaid number that is not bound to the business ΑΦΜ will be rejected during activation. If the ΑΦΜ on the telecom line does not match the ΑΦΜ on the signed provider agreement, the activation cannot proceed.

Practical checklist:

1. Use a company mobile or landline registered to your ΑΦΜ (check a recent bill — the ΑΦΜ is printed on it).
2. Enter it in international format (e.g. +30 210 1234567 or +30 69XXXXXXXX).
3. If you don’t have a business line yet, register one with any Greek provider under the company ΑΦΜ before starting the wizard.

3. Contract Signing

The provider agreement is pre-filled automatically with your details. Sign digitally inside the Shopify admin — no printing, scanning, or emailing required.

The signed PDF is stored securely and always available for download from your dashboard (Provider Contract tab).

4. Confirmation

The wizard completes and you gain access to the full dashboard.

Step 3: Provider Activation (AADE)

myDATA Comply works with Novus Conceptus, our official AADE-certified Electronic Invoicing Provider (Πάροχος Ηλεκτρονικής Τιμολόγησης). All submissions to myDATA are made through Novus Conceptus on your behalf — this is why the provider agreement and the TaxisNet authorization are required.

After signing the contract, our team initiates the AADE activation process with Novus Conceptus.

What happens next:

1. We relay your company details to Novus Conceptus
2. Within approximately 1 business day, you’ll receive a digital authorization request via TaxisNet
3. Accept the authorization — this allows the provider to submit documents to AADE on your behalf
4. Once accepted, your account is active and ready to submit!

Note

You only need to do this once. After authorization, all future submissions are automatic.

Existing Users

If you’re already using the app and are prompted to complete the activation form, this is expected. The process takes 3 minutes, your details are pre-filled, and it is required for the digital signing of the provider agreement.
