The Slovenian Parliament has unanimously adopted a new law on the exchange of electronic invoices and other electronic documents, introducing mandatory electronic invoicing for all business entities registered in Slovenia as of January 1, 2028. The reform is a decisive step towards a fully digital business environment and aims to simplify administrative processes, reduce costs and improve transparency throughout the economy.
The law applies to all legal entities and sole proprietors listed in the Slovenian Business Register (PRS) that supply goods or services in Slovenia. Consumers will still be able to decide whether they wish to receive electronic invoices and may withdraw their consent at any time.
Once the law comes into force, paper invoices will only be allowed for consumer transactions and cross-border business.
Economic and administrative impact
It is estimated that Slovenian businesses currently spend approximately EUR 814 million annually on issuing and receiving invoices. The new system is expected to reduce these costs by approximately EUR 238 million, or 29 percent, through process automation and the elimination of manual data entry.
In addition to the financial savings, the reform will bring other benefits, including
Improved data accuracy and security
Reduced administrative burden
Faster payment processing, and
a significant environmental impact through paper reduction.
The reform is widely supported by the business community, which sees it as an important step towards greater competitiveness, transparency and sustainability.
A digital milestone
The introduction of mandatory e-invoicing is seen as a key milestone in Slovenia’s digital transformation, enabling a more efficient, secure and greener economy. While some concerns have been raised about implementation costs and data protection, the overall consensus is that the benefits far outweigh the challenges.
