See the ones that fit youSlovenia's public procurement market is valued at approximately €5 billion annually, accounting for roughly 10% of the country's GDP. As a small but well-organized EU member state that joined in 2004, Slovenia has fully transposed EU procurement directives into national law. The market is characterized by a strong emphasis on infrastructure modernization, IT systems, and industrial supply chains — particularly in the automotive and pharmaceutical sectors. The country's strategic position at the crossroads of Central and Southern Europe makes it an important logistics and manufacturing hub. Public procurement in Slovenia is conducted primarily through electronic channels, with the e-JN system serving as the mandatory platform for most procedures. The market is accessible to EU suppliers, though knowledge of Slovenian language and local business practices provides a significant competitive advantage.
The mandatory electronic public procurement platform for Slovenia. All contracting authorities must publish tenders and accept submissions through e-JN. The portal handles the complete procurement lifecycle — from notice publication through bid submission to contract award. Registration is required to submit bids, and the system supports electronic signatures.

Slovenia applies standard EU thresholds as set by the European Commission. Below EU thresholds, national rules under ZJN-3 apply with simplified procedures. Small-value procurement (evidenčno naročilo) below €20,000 has minimal procedural requirements.
Slovenia is investing heavily in road, rail, and tunnel infrastructure. Major projects include motorway maintenance, railway modernization on the Pan-European corridors, and port expansion at Koper — the country's main maritime gateway. Opportunities exist for construction firms, engineering consultancies, and equipment suppliers.
The Slovenian government is actively digitizing public services and modernizing IT infrastructure across ministries and agencies. Opportunities include e-government platforms, cybersecurity, cloud migration, healthcare IT systems, and data management. The country's strong tech talent pool supports ambitious digital transformation projects.
Slovenia has a well-developed pharmaceutical industry, anchored by companies like Krka and Lek (Sandoz). Public procurement in healthcare covers hospital equipment, medical devices, pharmaceutical supplies, and healthcare facility construction. The aging population drives sustained demand for healthcare infrastructure and services.
The automotive sector, centered around Revoz (Renault's manufacturing plant in Novo Mesto), creates significant supply chain procurement opportunities. Related manufacturing sectors include electrical equipment, metal processing, and plastics. Public procurement supports industrial zone development and vocational training infrastructure.
Slovenia is pursuing renewable energy targets and environmental infrastructure upgrades. Opportunities include hydropower plant rehabilitation, solar energy installations, waste management systems, water treatment facilities, and energy efficiency retrofits of public buildings. The country's commitment to the EU Green Deal drives a growing pipeline of green procurement.
Register on the e-JN portal well before you plan to submit your first bid. The platform requires electronic signatures and has specific technical requirements. Familiarize yourself with the submission process, document upload formats, and deadline mechanisms. Technical issues at submission time are not accepted as grounds for late submissions.
Tender documents are published in Slovenian, and bids must typically be submitted in Slovenian. Invest in professional translation by translators familiar with procurement terminology. Poorly translated submissions reflect badly on your company and can lead to disqualification on technical grounds. Consider engaging a local partner or consultant to review your submissions.
If you believe a procurement process has been conducted unfairly, familiarize yourself with DKOM's review procedures before you need them. Review requests must be filed within 8 working days of the contested decision, and fees are proportional to the contract value. Seek legal advice from a Slovenian procurement law specialist for any significant dispute.
As an EU member state, Slovenia participates in EU-funded programs including Structural Funds, Cohesion Fund, and Recovery and Resilience Facility projects. Many large infrastructure and IT projects receive EU co-financing, which typically means stricter transparency requirements and broader publication — increasing opportunities for international suppliers.
For large contracts, consider forming consortia or joint ventures with Slovenian companies. Local partners provide language skills, understanding of administrative requirements, and established relationships with contracting authorities. The Slovenian Chamber of Commerce and Industry (GZS) can help identify potential partners in your sector.

Yes. The e-JN (Elektronsko javno naročanje) portal at ejn.gov.si is the mandatory electronic procurement platform. You must register and set up electronic signatures before you can submit bids. Registration is free but takes several days to complete, so plan ahead.
Generally no. Most Slovenian tenders require submissions in Slovenian. While some international or EU-funded tenders may accept English-language bids, this is specified in the tender documentation on a case-by-case basis. Always check the language requirements in the specific tender notice and budget for professional translation.

DKOM (Državna revizijska komisija) is the independent National Review Commission that handles public procurement disputes. To file a complaint, you must submit a review request (zahtevek za revizijo) to the contracting authority within 8 working days of the contested decision. A proportional fee must be paid. DKOM then reviews the case and issues a binding decision. Engaging a local procurement lawyer is strongly recommended.
EU-based companies have equal access to Slovenian procurement under EU single market rules. You may need to provide certificates and declarations equivalent to those required of Slovenian companies — such as tax compliance certificates, criminal record checks, and professional registrations. The European Single Procurement Document (ESPD) simplifies initial qualification. Non-EU companies should check bilateral agreements.
Main contractors on large Slovenian projects often seek subcontractors, especially for specialized works. Monitor awarded contracts on the Portal javnih naročil to identify active contractors. Industry associations like GZS (Chamber of Commerce) and OZS (Chamber of Craft and Small Business) maintain directories and organize matchmaking events. Networking at sector-specific trade fairs in Ljubljana is also effective.
