Why should you implement electronic invoicing and digital archiving? 

While electronic invoicing based on transaction type is currently just an option in Hungary, the obligation is expected to appear in more European countries in the coming years. 

According to the ViDA (VAT in Digital Ages) proposal package related to the EU's HÉA directive, which will come into effect in January 2024, a bill document containing only images would not be considered an electronic invoice. Member states are required to gradually incorporate the elements of the directive into their local regulations by 2028. Additionally, starting from 2028, mandatory electronic invoicing will be implemented for intra-community transactions.

The expansion of the Hungarian Online Invoice system framework and further adoption of XML-based invoicing by the NAV (National Tax and Customs Administration) is also expected by 2028.

In countries where electronic invoicing is mandatory, due to dynamically changing local requirements, a dedicated electronic invoicing interface module could be an effective aid. This module would uniformly facilitate communication with various central electronic invoicing systems available in different countries.

Based on the latest trends, a fundamental taxpayer expectation concerning central systems is the archiving of invoice documents. However, where this is not available, incorporating an archiving function into the business system could also be an effective solution.


We assess the company's operations, invoicing processes and systems.

We propose suitable electronic issuance and retention methods. 

We help navigate the practical functioning of archiving methods.

Cost-effectiveness is a primary consideration in system design. 

We provide continuous assistance for the implementation of the suggested system, even among third parties.

Legal Background

  • Rules regarding invoice issuance, mandatory content elements of invoices, and requirements for electronic invoices are specified in Chapter X of Act CXXVII of 2007 on Value Added Tax. Requirements for invoicing software are also outlined in Government Decree 23/2014 (VI. 30.) of the Ministry for National Economy regarding the tax identification of invoices and receipts, as well as the tax authority's control of electronically stored invoices.
  • Appropriate methods for preserving electronically stored documents are laid out in Government Decree 1/2018 (VI. 29.) of the Ministry of Innovation and Technology concerning the rules of digital archiving. According to Section 55 of Government Decree 451/2016 (XII. 19.) on the detailed rules of electronic administration, a certified copy of a paper-based original document can be created.
