About ProZorro

What is ProZorro?

ProZorro is a centralized, electronic open-source database enabling public procurement in Ukraine.

At the ProZorro website, you can find:

The website does not give you access to participate in tenders posted. To participate, you should register at a private platform.

Think of ProZorro and private platforms as you would of the Web and browsers through which access is provided.

Just like the Web, ProZorro holds data.

To access ProZorro, you can choose from a variety of websites, each having specific features. Regardless of the browser you use, the accessed data will be the same (even though visual representation may vary).

See how to work with platforms further in this guide.


ProZorro was developed as a joint effort of the Transparency International organization, the Ministry of Economic Development and Trade of Ukraine, volunteers, NGOs and other participants.

The ProZorro platform is owned and operated by the state enterprise ProZorro.

The following Ukrainian institutions are obliged to carry out procurements through ProZorro:

Other institutions and private legal entities may also use ProZorro for their procurements.

Volume of procurements through ProZorro in 2018

Number of tenders: 1,252,000

Bidders: 148,000

Purchasers: 28,340

Estimate savings for the state budget of Ukraine: equivalent to Can$1.6 billion


Data security

The State Service of Special Communication and Information Protection of Ukraine confirmed compliance of the integrated information security system with the law.


Participation of foreign bidders in 2018

Agreements with foreign bidders: 850 (0.1% of the total number of agreements) for a total of Can$3 billion (9% of the total cost of executed agreements)

Planned developments in ProZorro

ProZorro continues to undergo enhancement and development to enforce anticipated regulatory changes.

Ability to reject offers with an abnormally low price

This will help counteract predatory pricing. An abnormally low price is a winning price that is more than 40% lower than competitor prices at the initial stage and more than 30% lower at later stages.

Life cycle cost estimates

Procurement price is no longer the only criterion for winning a tender. The life cycle cost concept takes into account other buyer expenses during the course of using a procurement item.

Electronic catalogue

This is a database of up-to-date offers—a tool for purchasing small lots of typical products, similar to an online store.

Appeal procedure

If the Antimonopoly Committee of Ukraine rules in favour of an appeal, the money paid to submit the appeal must be reimbursed to the applicant. Recall of a submitted appeal will not be possible.

Business associations

Business associations, such as consortia, will be able to bid.

How to join

Choice of platform

To participate in procurements, bidders must use authorized electronic trading platforms. Regardless of the platform used, the tender data will be identical (even though the visual representation may vary).

Platforms with English interface :

Platforms with no or limited English interface:


After selecting a platform, the bidder must complete the registration and authorization process. Please note that in case of a negotiation procedure (explained further in section 4, Scenarios), registration is not required.

Registration and authorization take time, so make sure you register in advance.

Bidder can choose any platform. All platforms are connected to ProZorro and display the same information on procurements.

The following information is usually required:


Authorization procedures for foreign bidders vary on different platforms. Foreign companies may choose from the following procedures available on, and Opentenders.Online.

1. Signing a contract between the bidder and the platform
Contracts are usually bilingual. Generally, a scanned copy of the signed and sealed contract is enough for the authorization.

2. Bank payment of the invoice
The payment can only be made from the bidder’s current account. After the authorization, funds will either be returned to the bidder or added to the bidder’s account balance on the platform.

3. Electronic digital signature according to Ukrainian legislation
Note: An electronic digital signature issued by an authorized provider from a foreign country in Ukraine may not be used. Only a digital signature issued by a Ukrainian authorized provider may be used for the purposes of authorization.

4. Bank ID
Note: This option is available only for companies with an account at a Ukrainian bank.

5. Mobile operator ID
Note: This option is available only for phone numbers from Ukrainian mobile operators.

Reasons for rejection of a bidder’s participation

Buyers have the right to reject a bidder’s participation in a procurement for the following reasons:

Step-by-step guide

Bidding process at a glance

1. Select the opportunity

Each procurement page contains details and tender documents published by the buyer.

These usually include the following:

2. Clarify the terms

The buyer must provide clarifications to tender documents within three days of the question being published.

3. Pay the participation fee

Note: Payment has to be made from the bidder’s current account

4. Submit the tender offer

Tender documents may require bidders to provide a tender guarantee—a bank guarantee that is returned to the bidder later (except in certain cases).

A bank guarantee may be issued by your bank in the name of a Ukrainian bank that will re-issue its own guarantee to the buyer.

Follow these steps to submit the tender offer:

Bidders will be able to see each other’s tender offers from the earliest stage of the procurement.

In the case of below-threshold procurements, the period for tender offer submission is:

If a tender offer does not meet the tender document requirements, or if a bidder does not comply with the qualification criteria or does not provide a tender (bank) guarantee, the bidder’s tender offer will be rejected.

Practical insights

5. Auction

The auction takes place online on the automatically created auction page. It contains information about the tender and the field for making bids.

The auction platform main page contains the list of all current and anticipated auctions and their status in real time.

Information about the bidders’ tender offers is available to everyone via ProZorro, but the bidders’ prices will be hidden until the start of the auction.

In addition to the price criterion used for the assessment of tender offers, the buyer may set other non-monetary qualitative criteria such as terms of payment, execution deadline and guarantee services.

If setting non-monetary criteria, the buyer must establish a formula for calculating the bidders’ compliance with these criteria. Based on the formula, ProZorro automatically recalculates the bidders’ price offers and establishes the “corrected price.”

In such a case, the bidders start bidding from the corrected price.

6. Qualification stage

The qualification stage may be held after or prior to the auction, depending on the type of procurement.

These steps take place during the qualification stage:

7. Contract execution

The contract is executed between the tender winner and the buyer according to Ukrainian legislation.

The contract is executed only after the end of the term for appeal, which, depending on the procurement scenario, is 10 days after:

8. Complaints

If you suspect that violations took place during your procurement, you can file a complaint to a number of authorities. Templates for the most common types of complaints can be found at the DoZorro website.


Please refer to Annex 2 for typical violations, respective authorities you can report to and possible complaint results.


Types and thresholds

There are certain modifications to the standard process depending on the type of procurement and the value in relation to the threshold*

An important factor to know about thresholds is that above-threshold procurements must be published on the ProZorro website. Most worthwhile public opportunities are above threshold.

* For more details on thresholds, please refer to Annex 3.

Type of procurement


Open tender


The most commonly used procurement procedure



To choose the most appropriate offer in terms of price and compliance with the eligibility criteria

Open tender published in English


The procedure of open tender published in English is the same as the open tender procedure, except for steps 5 and 6


If the expected value of procurement exceeds:

Competitive dialogue


A less commonly used procurement procedure



To optimize the procurement’s goals through a dialogue with bidders

Negotiation procedure


The only procedure held offline (not via platforms)


Most commonly used when:


To optimize the procurement’s goals through negotiations, in order to find eligible bidders.

Note: The buyer will require the bidder(s) to submit compliance-related documents during negotiations.

Challenges and tips

Foreign bidders may face specific issues. Below are the most common ones and how to deal with them.


Most of the information is in Ukrainian.

Different platforms with English interfaces may have different translations of the same term or definition. For example:

Usually, tender documents are published in Ukrainian. The buyer may publish tender documents prepared in English at its own discretion.

A foreign bidder may consider engaging a translator.

Registration on platforms

Not all platforms allow registration and authorization of foreign companies. A number of platforms that do are mentioned on page 14.

Authorization on platforms

Authorization on platforms might take longer due to the execution of service contracts with the platform. Some authorization options (foreign digital electronic signature, mobile ID, foreign bank ID) may not be available for foreign companies.

Participation of foreign companies

Tender documents might lack information on foreign companies’ participation in procurement. In such cases, you may ask the buyer for clarification of tender document requirements if needed.
A common issue is when tender documents require bidders to submit documents that only Ukrainian bidders can have (such as confirmation of registration in the Ukrainian Register of Companies). In such a case, foreign bidders should query the buyer. Usually, foreign bidders submit equivalent documents issued in their country of registration.

Currency conversion

The currency for procurements is UAH. The system has no automated currency conversion option.  Therefore, bidders will need to make currency conversions themselves.
The National Bank of Ukraine provides the official exchange rate of UAH to foreign currencies. You may also choose from a number of online currency converters.

Please make sure that the authorization is completed in advance of bidding on a tender.
