WooCommerce gives you full control over your WordPress store — but that control usually comes with a plugin for everything, including invoicing. More plugins mean more updates to manage and one more thing that can break your checkout at the worst possible moment.

A WooCommerce–myDATA integration built on webhooks skips all of that. No plugin lives on your site. Orders are simply detected and converted into compliant receipts or invoices in the background.

Why this matters for WooCommerce store owners in Greece

Every receipt or invoice issued in Greece has to be transmitted to myDATA under AADE regulations. For a WooCommerce store, that usually means either a locally installed invoicing plugin that adds its own maintenance overhead, or manually pulling order data and issuing documents by hand.

Neither scales well once you're processing meaningful order volume, and plugin-based solutions in particular tend to be the first thing to break after a WordPress or theme update.

How it works — no plugin required

Instead of a plugin, the connection runs through WooCommerce Webhooks, a native WordPress/WooCommerce feature:

• A customer places an order on your WooCommerce store.
• The order status updates (e.g., marked as completed/fulfilled).
• WooCommerce's built-in webhook system notifies the Workadu directly.
• The platform generates the correct document — receipt or invoice — with no accounting configuration needed from you.
• The document is sent to myDATA, directly or through a certified e-invoicing provider.
• A copy is automatically emailed to the customer.

Because it uses WooCommerce's native webhook system rather than a plugin, there's nothing extra installed on your site to slow it down, conflict with other plugins, or need updating every time WordPress does.
