Who is the webinar suitable for?

The webinar is intended for companies that will deal with issuing, receiving or processing electronic invoices in Slovakia.

It is suitable for:

  • our customers who want to know how their ORiON EDI can prepare for new requirements,
  • financial managers , accounting teams and teams responsible for invoicing ,
  • IT managers, ERP specialists and process analysts ,
  • companies with an ERP, accounting or invoicing system ,
  • sales, logistics and operations teams affected by the flow of orders, deliveries and invoices,
  • accounting offices that process documents for several clients ,
  • companies that do business with Slovak partners or are preparing for a wider European digitization of invoicing .

Why come?

As of January 1, 2027, e-invoicing in Slovakia will become mandatory for domestic B2B and B2G transactions. The electronic invoice will no longer be just a PDF document sent by e-mail, but a structured data document intended for automatic processing in the Peppol format.

For companies, it will not just be a change in the format of the invoice. It will touch on the way invoices are created, sent, received and processed in the accounting or ERP system.

Many companies today already use ERP, an accounting system or EDI. Nevertheless, they will need to verify that their current processes and systems can meet the new requirements .

Typically it will be necessary to address:

  • how to receive and send e-invoices in the correct format,
  • how to ensure a connection to an ERP or accounting system,
  • how to manage the control and processing of invoices without manual intervention,
  • what role will the certified delivery service play,
  • how to prepare the company for new processes without unnecessary chaos.

In the webinar, we will show what is really changing, what the company should check in time and how to prepare systematically and ahead of time for mandatory e-invoicing.

What will you take away from the webinar?

Overview of what changes from 1/1/2027

We will explain to whom mandatory e-invoicing applies, what is the difference between a PDF invoice and a structured e-invoice, and why it is important to start preparing already during the year 2026.

A clearer idea of the role of the Digital Postman

We will show why a certified delivery service will be important when sending and receiving e-invoices and what it should ensure in practice: format control, delivery to the correct recipient, feedback in the event of an error and connection to company systems.

A practical view of ERP, accounting and internal processes

We'll go over what companies should check with their ERP, accounting or invoicing system and how to set up collaboration between IT, finance, accounting and solution providers.

A look at ORiON EDI as a basis for e-invoicing

We will show ORiON EDI customers why they are not starting from scratch. ORiON already works with the structured exchange of business documents today, and therefore can be a natural basis for handling the new requirements for electronic invoicing.

Concrete steps, what to solve in 2026

You will take away a practical framework for how to think about preparation: from checking current processes through technical connections to setting responsibilities and testing the exchange of invoices.
