How to Bid for Public Contracts in Croatia: A Step-by-Step Guide

Winning a public contract can be a turning point for a business. In Croatia, public bodies—from local councils to national ministries—regularly buy goods, services and works through a transparent, EU-aligned procurement system. For companies that take the time to understand the process, it can open the door to reliable, long-term revenue.

The system is governed by the Public Procurement Act, which transposes EU directives into Croatian law. All tenders above certain thresholds are published electronically, and bids must be submitted online. This guide explains the essential steps, from registering as a bidder to avoiding the most common mistakes.

Who can bid for public contracts in Croatia?

Any legally established business—Croatian or from another EU member state—can bid for public contracts. In most cases, there is no need for a local branch; a registered company address within the EU is sufficient. Sole traders (obrti) and large corporations compete on equal terms, and public buyers must treat all bidders fairly and without discrimination.

Some contracts are reserved for small and medium-sized enterprises or for sheltered workshops employing persons with disabilities, but these are clearly marked in the tender documents. Make sure your business activity matches the procurement object; the buyer will check your professional registration in the relevant trade or court register.

Step 1: Register on the national e-procurement system

All public procurement in Croatia is carried out through the Electronic Public Procurement System (EOJN). To submit a bid, you must first create an account and obtain a digital certificate. The certificate can be issued by the Financial Agency (Fina) or other certified providers. The registration is free of charge.

Once registered, you can search for open tenders, download documentation and ask clarifying questions. The system also stores your company profile, which saves time when submitting multiple bids. Keep your profile updated with current contact details and legal information.

Step 2: Find suitable tender opportunities

All public tenders above the EU thresholds are published in the Official Journal of the EU’s Tenders Electronic Daily (TED) and simultaneously in the EOJN. Below-threshold tenders are published only in the EOJN. You can set up automatic alerts based on keywords, CPV codes (Common Procurement Vocabulary) and contract type.

Pay close attention to the type of procedure: open procedure means any interested company can bid; restricted or negotiated procedures involve a pre-qualification stage. Also note whether the contract is divided into lots—this is increasingly common and allows smaller businesses to bid for a portion of a larger requirement.

Step 3: Prepare a compliant bid

Read the entire tender documentation before doing anything else. The most frequent reason for rejection is not failing to meet technical requirements but omitting a required document or signing in the wrong place. Make a checklist of every form, certificate and statement requested.

Your bid will normally consist of two parts: the administrative and technical offer, and the financial offer. You must complete the European Single Procurement Document (ESPD), in which you declare that you meet all selection criteria and that there are no grounds for exclusion (such as criminal convictions or unpaid taxes). The buyer may later ask you to provide proof.

For the financial offer, price is not always the only criterion. Many tenders use the “most economically advantageous tender” (MEAT) approach, which includes quality, delivery time, warranty or environmental aspects. Make sure you understand the weighting of each criterion before setting your price.

Step 4: Submit the bid on time

Bids are submitted exclusively through the EOJN. The deadline is strict: the system will not accept late submissions. Give yourself at least a day of buffer time to deal with technical issues. After submitting, you will receive an electronic receipt confirming the time and date.

You may withdraw or modify your bid before the deadline, but once the deadline passes, it is locked. If you have any doubts about the documentation, send a question through the system during the clarification period. The buyer is obliged to publish answers to all questions, so also check for updates regularly.

Step 5: After the decision

Once bids are evaluated, the buyer publishes a decision to award the contract. All bidders are notified through the EOJN. If you are not successful, you have the right to request a review of the decision by the State Commission for Supervision of Public Procurement Procedures. The request must be filed within 10 days of receiving the decision.

If you win, the next step is signing the contract and, if required, providing a performance guarantee. Read the contract carefully—especially provisions on penalties, termination and payment terms. Public buyers in Croatia generally pay within 30 to 60 days, but this can be negotiated.

Common pitfalls to avoid

• Missing a required document or signature – use a compliance matrix to check every item.
• Ignoring amendments to tender documents – always check the EOJN for updates before submitting.
• Underestimating administrative burden – keep your company’s basic documents (registration, tax clearance, insurance) ready in digital form.
• Bidding too low – unsustainable prices can lead to contract failure and penalties.
• Not asking questions – clarification questions are anonymous and protected, so use them to resolve any ambiguity.

Public procurement in Croatia is formal and rule-based, but it rewards preparation and persistence. For many businesses, winning one public contract opens the door to more, as past performance is often a scoring element in future tenders. Start with smaller, local tenders to build experience, then move to larger opportunities.
