Who is the webinar suitable for?

The webinar is intended for Czech and Slovak 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 invoicing teams,
  • IT managers, ERP specialists and process analysts,
  • companies with ERP, accounting or billing systems ,
  • sales, logistics and operations teams concerned with the flow of orders, deliveries and invoices,
  • accounting offices that process documents for multiple clients,
  • companies that trade with Slovak partners or are preparing for the broader European digitalization of invoicing.

Why come?

From January 1, 2027, electronic invoicing will become mandatory for domestic B2B and B2G transactions in Slovakia. An electronic invoice will no longer be a simple PDF document sent by email, but a structured data document intended for automatic processing in Peppol format.

For companies, this will not just be a change in invoice format. The change will affect the way invoices are created, sent, received, and processed in accounting or the ERP system.

Many companies already use ERP, accounting systems or EDI, but they will need to verify whether their current processes and systems can meet the new requirements .

Typically, you will need to address:

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

In the webinar, we will show what is actually changing, what a company should check in a timely manner, and how to prepare for mandatory electronic invoicing systematically and in advance.

What will you take away from the webinar?

Overview of changes valid from 1. 1. 2027

We will explain who is affected by mandatory electronic invoicing, what is the difference between a PDF invoice and a structured electronic invoice, and why it is important to start preparations as early as 2026.‍

A clearer understanding of the role of the digital postman

We will show why a certified delivery service will be important when sending and receiving electronic 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 look at ERP, accounting and internal processes

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

A look at ORiON EDI as a basis for electronic invoicing

We will show ORiON EDI customers why they don't have to start from scratch. ORiON already works with structured business document exchange today and can therefore be a natural basis for handling new requirements for electronic invoicing.‍

Specific steps to be addressed in 2026

You will take away a practical framework for how to think about preparation: from reviewing existing processes to technical connections to setting responsibilities and testing invoice exchange.
