Electronic Invoicing for Hotels and Accommodation Businesses

Issue Receipts and Invoices Directly through EasyBookings

Create retail receipts and invoices directly through EasyBookings, automatically using the details of your bookings, customers, rooms and additional services.

EasyBookings supports a different issuance channel depending on the type of transaction: direct transmission to AADE myDATA for documents that may be issued through an ERP system, and electronic B2B issuance through the licensed Primer MyData service.

Following successful transmission, EasyBookings automatically records the MARK and the issuance details, providing a complete invoicing workflow from within your accommodation management system.

Which Documents Are Covered by Mandatory Electronic Invoicing?

Mandatory electronic invoicing mainly concerns invoices between businesses:

• domestic wholesale transactions between businesses — B2B,
• B2B transactions with businesses established in non-EU countries,
• transactions with public-sector bodies — B2G.

Standard retail receipts issued to private individuals — B2C — are generally not subject to the requirement to be issued through an Electronic Invoicing Provider. However, the applicable requirements for issuing them and transmitting their data to myDATA continue to apply.

For mandatory B2B electronic invoices, direct transmission from an ERP system to myDATA is not sufficient. They must be issued through a licensed Electronic Invoicing Provider or through the AADE timologio and myDATAapp applications.

Implementation Timeline

According to the current AADE implementation schedule:

• For businesses with gross revenue exceeding €1,000,000, based on tax year 2023, the requirement has applied since 2 March 2026.
• For all other businesses, the requirement applies from 2 November 2026.
• A gradual compliance period is available until 31 January 2027, provided that the relevant AADE declaration requirements were met on time.

As the application of the legislation depends on the type of transaction and the circumstances of each business, we recommend confirming your specific obligations with your accountant or tax advisor.

From the Booking to the Document

Select a booking and EasyBookings automatically completes:

• Customer details,
• Arrival and departure dates,
• Rooms and overnight stays,
• Accommodation charges and additional services,
• Discounts and coupons,
• The booking reference,
• The applicable VAT rates.

Before issuance, you can review and edit the document, select the appropriate series and view the final preview. Numbering is assigned securely when issuance begins, and transmission takes place only following a user action.

Two Issuance Channels

Secure and Controlled Transmission

EasyBookings protects the issuance process against duplicate or simultaneous submissions, whether the document is transmitted directly to AADE or through Primer. If a temporary communication problem occurs:

• Every transmission attempt is recorded in detail,
• The system checks whether the document has already been received,
• Safe retries are performed where permitted,
• A complete record of requests and responses is retained,
• A document that has already received a MARK cannot be issued again.

For Primer services, each business and VAT number is activated separately and has its own connection credentials and document package.

Why Use EasyBookings?

Invoicing is not a separate, isolated application. It connects directly to the information you already manage:

• Reservations,
• Customers,
• Rooms,
• Additional services,
• Discounts,
• Payments,
• Businesses and VAT numbers.

You do not need to enter the same information again in another system.

How Does It Work?

• Select a booking or create a new document.
• EasyBookings completes the customer details and creates the relevant document lines.
• Select the business, document type and document series.
• Review, edit and save the document as a draft.
• Preview the final document before submission.
• The document is sent through the appropriate channel: directly to AADE or through Primer.
• EasyBookings records the MARK and the document issuance details.
• View the PDF and send it to your customer.

Packages per Business

The Primer connection is activated separately for each VAT number. Every business has its own credentials and its own annual document package.

EasyBookings customers can select the package that best matches their annual document volume and the needs of their accommodation business.

Direct transmission through the AADE ERP API is a separate channel and does not use documents from the Primer package.
