Slovenia is at the forefront of eInvoicing adoption in Europe, embracing this technology to streamline business processes and enhance transparency in public and private transactions. This blog post dives into the current state of eInvoicing in Slovenia, guiding businesses through B2G and B2B regulations and highlighting the numerous benefits of adopting this technology.

State of eInvoicing in Slovenia

Early Adoption: Slovenia has been a pioneer in eInvoicing, implementing mandatory electronic invoices (e-invoices) for public sector transactions since 2015.

The e-invoice in Slovenia consists of the following documents:

  • E-Invoice Envelope, E-Invoice Envelope Schematic (an XML document designed to guide the e-Invoice).
  • e-SLOG, UBL 2.1 and CEFACT 100.D16B (standardised format of the e-Invoice in XML structure).
  • Optional attachments (e.g. visualisation of the e-invoice in PDF format) - Source.

In Slovenia, electronic signatures are not mandatory for e-invoices.The archiving period for e-invoices is 10 years, and it increases to 20 years for immovable property. So, while an electronic signature is not required, proper compliance with the specified formats and archiving periods is essential for e-invoicing in Slovenia.

Slovenian government introduced eInvoicing regulations beceause they understand why electronic invoices outperform PDF-based and paper invoices:

  • eInvoicing improves visibility of invoices and taxes,
  • It provides a quick and accurate overview of individual transactions,
  • eInvoicing streamlines the invoicing process,
  • eInvoicing saves costs in processing and delivering invoices (e.g. printing, postage, etc.),
  • It eliminates the need to display invoices on websites,
  • It removes barriers for businesses to cross-border communication and electronic, invoicing between EU countries.

B2G eInvoicing in Slovenia

B2G Compliance: All businesses supplying goods or services to public authorities in Slovenia are required to use e-invoices, adhering to specific technical standards.

B2B Adoption: While not mandatory for business-to-business (B2B) transactions, eInvoicing is gaining traction due to its numerous advantages, including faster processing, reduced errors, and improved efficiency.

Mandatory for All Suppliers: All businesses engaging in public procurement must use the PPA eInvoicing system, a centralized platform developed by the Public Payments Administration (UJP).

Peppol Integration: The PPA eInvoicing system integrates with the Peppol network, enabling seamless send and receive of e-invoices across borders with Peppol ID-registered businesses in other countries like the United Kingdom and Saudi Arabia.

B2B E-Invoicing in Slovenia

Voluntary Adoption: B2B eInvoicing remains voluntary, allowing businesses flexibility in choosing their approach.

Growing Popularity: Despite not being mandatory, B2B eInvoicing is becoming increasingly popular due to its cost-saving benefits and improved efficiency in managing business documents.

Standardized Formats: Businesses have access to various eInvoicing solutions and software that utilize Peppol BIS formats like Peppol invoice (UBL) to ensure smooth communication and compatibility across different platforms.

Looking Ahead

eInvoicing is becoming the standard for both B2G and B2B transactions across the European Union. By staying informed about eInvoicing regulations and exploring available solutions, businesses in Slovenia can leverage the power of this technology to:

  • Reduce administrative burdens associated with paper-based invoicing
  • Improve cash flow through faster invoice processing and payments
  • Minimize errors in data entry and document management
  • Enhance security and compliance with EU regulations
  • Gain a competitive edge by offering a streamlined and efficient business process to partners

eInvoicing is becoming increasingly important in both B2B and B2G transactions across Europe. A few years ago, it was mostly voluntary and only those who were aware of the security, convenience and data automation benefits of e-invoicing took advantage of it. Today, if you are a company registered in Slovenia or have Slovenian business partners, you need to comply with B2B eInvoicing regulations both in Slovenia and in your country of registration.
