Ukraine. ProZorro is a
hybrid electronic public procurement system based on open source and OCDS principles.

ProZorro is a hybrid electronic open source government e-procurement system
created as the result of a partnership between business, government and civil
society and built on the principles of open contracting.

ProZorro is a fully online public procurement platform and a collaboration environment that ensures open access to public procurement (tenders) in Ukraine. Fully implemented in 2016 as a hybrid (both centralized public and decentralized private marketplaces) system, it has since been globally recognized as one of the most innovative public procurement systems delivering government services in a stakeholder-focused, transparent, effective, fair and low-cost way.
In May 2016, Ukraine officially joined the WTO Government Procurement Agreement, which not only opens up the markets of its members – including 28 European nations, the US, Canada, and Japan – to Ukrainian suppliers, but also demonstrates the Ukrainian system’s compliance with international standards.

What has Prozorro changed?

All public tenders are announced
and conducted online

A clear contract award process

- The system collects full information about goods, services or works that are offered by the winner of the contract together with the contract itself and any amendments.

Our philosophy

Given that from the very beginning the ProZorro team was quite diverse, operated on a voluntary basis and endeavored to get quick results, we all agreed on a philosophy based on the following three key elements :

A hybrid electronic system based on an open-source model. Transactions take place in the central database. Any number of commercial marketplaces provide front-end access to the database. Marketplaces compete with each other which motivates them to provide the best service in order to attract both contracting entities and suppliers.


“Everyone can see everything” – the official motto of ProZorro. Following completion of a tender procedure absolutely all data is disclosed, including the list of all participants, their bids, auction process, decisions of the tender committee and all qualification documents, etc. This information is publicly accessible through ProZorro’s online analytics module.


A Golden triangle of partnership – a unique form of collaboration between business, state and civil society where functions are divided between different stakeholders to ensure independence and mutual control. Such partnership aims at promoting change while maintaining a high level of trust between principal stakeholders throughout the course of this reform.
