What is Prozorro?
Prozorro (prozorro.gov.ua) is Ukraine's public procurement e-system — the central open-data database through which all state, municipal, and state-owned enterprise procurement flows. Launched after 2014 as a joint effort of civil society, business associations, and the Ministry of Economic Development, Prozorro is one of the most internationally recognized open-source procurement platforms and has received awards from the Open Government Partnership and World Procurement Awards.
Prozorro uses a distinctive hybrid architecture. Rather than a single state-run portal where vendors bid directly, Prozorro federates multiple authorized commercial e-procurement platforms — such as SmartTender, Zakupki.Prom.ua, and E-Tender — which all funnel tender data into the central Prozorro database. Buyers publish through any authorized platform, vendors bid through any authorized platform, and all data is consolidated and made openly available on prozorro.gov.ua.
The system is backed by Transparency International Ukraine, whose DOZORRO civic monitoring initiative uses Prozorro's open data to flag risky tenders and support community oversight.
What Prozorro publishes:
- Tender announcements — above-threshold and below-threshold procurements for goods, services, and works
- Contract award notices — winner, price, and executed contract data
- Annual procurement plans — forward-looking purchase intentions from contracting authorities
- Tender documents — technical specifications, terms of reference, and draft contracts
- Complaints and AMCU decisions — Antimonopoly Committee of Ukraine review body rulings
- ProZorro.Sale — a sister system for state asset auctions and privatization, built on the same open-source stack
Key fact
Prozorro processes hundreds of billions of UAH in public procurement each year across central ministries, local hromada councils, and state-owned enterprises. Reconstruction and defence-related procurement have become the system's largest priority lines, with significant co-financing from the EU, World Bank, and EBRD. Public procurement represents a meaningful share of Ukraine's GDP and is the main commercial channel into the country's reconstruction economy.
Thresholds: above and below the line
Ukraine's Law on Public Procurement (Law No. 922-VIII, as amended) defines two core regimes: above-threshold procurement, which follows full competitive procedures, and below-threshold (simplified) procurement for smaller values. Thresholds differ for goods and services versus works, and for public-sector buyers versus utility-sector buyers.
| Regime | Category | Procurement Method |
|---|---|---|
| Below threshold | Goods / services — small value | Simplified procurement or direct contract with reporting |
| Below threshold | Works — small value | Simplified procurement or direct contract with reporting |
| Above threshold | Goods / services — public buyers | Open tender on Prozorro (mandatory) |
| Above threshold | Works — public buyers | Open tender on Prozorro (mandatory) |
| Above threshold | Goods / services — utilities / state enterprises | Open tender, higher value trigger |
| Above threshold | Works — utilities / state enterprises | Open tender, higher value trigger |
| Special cases | Defence / emergency | Negotiated procedure with reporting on Prozorro |
Specific UAH thresholds have been revised several times during wartime and reconstruction. Always confirm the current values in the Law on Public Procurement and Cabinet of Ministers resolutions before bidding. Above-threshold tenders are where international vendors will find the bulk of accessible, EU-aligned opportunities.

How to register and bid on Prozorro
Unlike a single-portal system, Prozorro requires you to register on one of the authorized commercial e-procurement platforms. Once registered on any one of them, you can bid on any tender in the Prozorro database.
What you need:
- Legal entity registration — for Ukrainian companies, an EDR (Unified State Register of Legal Entities) record; for foreign companies, equivalent incorporation documents
- Tax ID — Ukrainian EDRPOU code for domestic entities, or foreign tax identification for international bidders
- Platform account — register with one of the authorized e-procurement platforms (SmartTender, Zakupki.Prom.ua, E-Tender, etc.). There is no fee to view Prozorro data, but platforms charge transaction fees to submit bids
- Qualified electronic signature (QES) — Ukrainian law requires a QES for bid submission. Foreign bidders can obtain a compatible signature through accredited providers or designate an authorized representative with a Ukrainian QES
- Bid security — many above-threshold tenders require a bank guarantee as bid security
Foreign companies note: Ukrainian procurement law permits participation by foreign vendors without requiring a local subsidiary. Certified Ukrainian translations of corporate documents are typically required. For reconstruction projects with international co-financing, donor rules (EU, World Bank, EBRD, USAID) may layer additional qualification criteria on top of the Prozorro process.

Procurement procedures on Prozorro
Ukraine's Law on Public Procurement defines a set of procedures that align with EU Directive 2014/24/EU. The procedure is determined by the value, subject matter, and nature of the procurement.
- Open tender (відкриті торги) — the default procedure for above-threshold procurement. Fully competitive, electronic, with reverse-auction price clarification
- Open tender with features — open tender with additional qualification, innovation, or sustainability criteria beyond lowest price
- Simplified procurement (спрощена закупівля) — below-threshold procedure with lighter publication and timing requirements
- Negotiated procedure — restricted to specific legal grounds (e.g. single supplier, urgency, defence, failed prior tender). Requires published justification
- Dynamic Purchasing System (DPS) — fully electronic system for recurring standardized purchases, open to new vendors throughout its validity
- Framework agreements — multi-year contracts with one or several suppliers for recurring needs; call-offs are published on Prozorro
- Competitive dialogue — used for complex procurements where requirements cannot be fully defined upfront
Hook monitors Prozorro for you
Prozorro publishes tens of thousands of tenders per month across central ministries, hromada councils, and state-owned enterprises. Hook indexes all of them — letting you search in English, filter by sector, value, and buyer, and get alerts when relevant reconstruction or supply contracts appear.

Prozorro's open data is one of the richest procurement datasets in the world. The native interface and authorized platforms support filtering by buyer, CPV code, procedure, status, region, and value.
Tips for effective searching:
- Use CPV codes — Prozorro uses the EU's Common Procurement Vocabulary alongside Ukraine's national classifier (ДК 021:2015), so CPV codes you already know from EU markets work here
- Learn the procurement identifier format — tenders are numbered UA-YYYY-MM-DD-XXXXXX-a, where the date is the publication date. Once you know the ID, you can pull the full record across any authorized platform
- Filter by contracting authority to track specific ministries, hromadas, or state-owned enterprises — reconstruction-heavy buyers are especially active
- Check annual procurement plans to anticipate upcoming tenders up to a year in advance
- Monitor contract award data and historical pricing — Prozorro's open data includes winners, prices, and performance metrics
- Watch for framework agreements and DPS — they let you capture recurring demand without bidding on every individual call-off
The main limitation of the native search is that it is keyword-based in Ukrainian. Hook's semantic search bridges this gap — search in English and find relevant Ukrainian tenders regardless of how they are titled.
Common questions about Prozorro
Can foreign companies bid on Prozorro tenders?
Yes. Ukraine's Law on Public Procurement does not restrict foreign participation, and the country's EU association agreement commits Ukraine to non-discriminatory procurement. Foreign companies bid on equal terms with Ukrainian vendors, provided they register on one of the authorized e-procurement platforms and submit the required documentation. For reconstruction contracts, donor-funded tenders may follow additional rules set by the EU, World Bank, EBRD, or USAID.
What is the difference between Prozorro and DOZORRO?
Prozorro is the central state procurement database and the name of the system itself. DOZORRO is an independent civic monitoring initiative led by Transparency International Ukraine that analyzes Prozorro data to detect risky tenders, supports community oversight, and lets citizens and businesses flag suspicious procurements. Prozorro handles the transactions; DOZORRO watches them.
Which e-procurement platform should I use to bid?
Prozorro uses a hybrid architecture: multiple commercial e-procurement platforms (SmartTender, Zakupki.Prom.ua, E-Tender, and others) are authorized to submit bids into the central Prozorro database. Notices appear on all platforms, so you can search anywhere, but you need an account on at least one authorized platform to submit bids. Choose based on interface language, support, and fees.
How does Ukraine's reconstruction affect procurement opportunities?
Reconstruction has become Ukraine's largest procurement priority. The Ministry for Restoration, Ukrzaliznytsia, local hromada councils, and defence-related buyers run large volumes of works and supply tenders on Prozorro, often with EU, World Bank, or EBRD co-financing. Many reconstruction tenders are aligned with EU procurement rules as part of Ukraine's EU accession track, lowering the barrier for European contractors.
Is Prozorro aligned with EU procurement directives?
Ukraine's Law on Public Procurement has been progressively aligned with EU Directive 2014/24/EU as part of the EU association and candidate status process. Procedures, above-threshold publication, and review mechanisms follow the EU model, and CPV classifications are used. Full alignment is ongoing and is a condition of EU accession negotiations.
