Features

myDATA Comply submits your tax documents to AADE’s myDATA from the Shopify order page. One app covers the retail receipt on a doorstep delivery, the B2B invoice for a company customer, the consignment shipment, and the sale to a customer in another EU country — with no myDATA credentials and no separate invoicing portal.

Every document your store needs

One click from every order

Open any order in your Shopify admin, choose the document, and submit. You never leave Shopify.

1. Open the order
2. Click Submit to myDATA
3. Pick the document type (and add an optional note)
4. Get your MARK number and a PDF within seconds

Supported document types

Document	myDATA type	Use it for
Retail receipt	11.1	B2C sales without shipping — digital goods, services, in-store pickup
Retail receipt with delivery note	11.1 + delivery note	Shipped B2C orders — the standard for Greek e-commerce
Sales invoice	1.1	Company customers who need a full invoice
Sales invoice with delivery note	1.1 + delivery note	Shipped B2B orders
Delivery note	9.3	Moving goods without a sale here — consignment, return, free disposal, or a sale you invoice elsewhere
Sale on behalf of third parties	1.4	Selling goods that belong to someone else, as an agent or on consignment
Clearance of third-party sales	1.5	Settling those sales with the owner, including your commission percentage
Retail receipt on behalf of third parties	11.5	Retail receipts for third-party goods

B2B invoicing

Issue a proper invoice to a company in a few fields: the recipient’s VAT number (validated before it is sent), tax office and business activity. Tick Save for future orders and the details are filled in for that customer next time. Everything appears on the PDF.

Delivery movements, the way AADE expects them

Choose the movement purpose — sale, consignment, return or free disposal. The picker only offers combinations myDATA accepts, so you don’t find out about a mismatch from a rejection. Sale on a standalone delivery note covers merchants who issue the receipt or invoice elsewhere (a till, another system) and only report the goods movement here.

Consignment and agent sales

Sell goods on behalf of a supplier with the dedicated third-party document types. The clearance document (1.5) carries your commission percentage, and cancelling a third-party sale (1.4) or receipt (11.5) issues the correct credit document automatically.

Notes on every document

Add an optional free-text note to any document. It prints on the PDF under Remarks.

Cancellations & credit notes

Cancel or credit a document from the same order page. Delivery notes are cancelled directly; receipts and invoices get the matching credit document (retail credit note or credit invoice), and AADE is notified immediately. A double-click or a retry can’t cancel the same document twice.

Multiple documents per order

An order is no longer limited to one document. Ship first and invoice later, correct a mistake, or refund part of an order — every document stays on the order:

• A delivery note when the goods leave
• A receipt or invoice when you bill
• Credit documents when something is cancelled or returned

Each document is listed with its own status badge and its own menu to download the PDF or cancel it. Cancelling one document never touches the others, and the app still stops you from submitting the same document twice.

Sell across borders: EU OSS and non-EU export

Selling to customers outside Greece? Turn the scheme on once in Settings and the app handles the VAT treatment for you.

• EU One-Stop Shop (OSS) — B2C sales to consumers in other EU countries are submitted with the correct OSS treatment.
• Non-EU export — orders shipped to destinations outside the EU, such as the US, are submitted zero-rated as exports.

The app checks the destination country, shows a warning when a case is unclear so you can confirm before submitting, and leaves Greek domestic orders exactly as they were. Cross-border PDFs carry an OSS/export notice box, and a credit note for a cross-border document repeats the original’s scheme so AADE accepts it.

Note

Both options are off by default. Enable OSS only after registering for the OSS Union scheme with AADE and enabling EU VAT collection in Shopify. Confirm export treatment with your accountant.

Automatic PDF generation

Every submission produces a redesigned PDF that is clear to read and easy to hand to a customer or an accountant:

• Your company details (name, VAT number, address)
• The customer’s details, including their real country and, for B2B, their tax office and business activity
• Itemised lines with the VAT applied shown on every document
• Movement purpose and your notes
• The OSS/export notice on cross-border documents
• The official myDATA QR code, MARK number and submission time

Download: from the confirmation link after submission, or from the order at any time.

Customisation: add your company logo from Settings.

Dashboard

Track everything from your Shopify admin:

• Submissions grouped by order — each order with its documents and events nested by date, instead of one long flat list
• Quota Indicator — how many submissions remain in the current billing cycle
• Subscription Status — your plan and renewal date
• News — the latest features and updates

Document statuses

Each document shows a badge that reflects its real state:

Status	Meaning
Active	Accepted by AADE, MARK assigned
Voided	Cancelled — a credit document or cancellation was issued
Pending	AADE was offline — queued, sends automatically
Failed	Rejected — check the error message

Tip

Pending submissions require no action — they are sent automatically when AADE comes back online and do not count toward your quota until confirmed.
