How to find and win government tenders in Bulgaria.
Bulgaria's government tenders are managed through CAIS (Централизирана автоматизирана информационна система «Електронни обществени поръчки») at app.eop.bg, the country's national e-procurement platform. This guide covers how to register, find opportunities, and compete for Bulgarian public contracts.
Four steps to your first Bulgaria government contract.
1
Register on CAIS at app.eop.bg
Create a supplier account using your Bulgarian UIC (Unified Identification Code for Bulgarian entities) or equivalent foreign company registration. Registration unlocks access to full tender documentation and enables electronic bid submission.
2
Search active procurement notices
Browse CAIS by CPV code, contracting authority, procedure type, or status. Above EU thresholds, Bulgarian contracts are also published on TED (ted.europa.eu). Monitor both channels to get full market visibility.
3
Prepare and submit your electronic bid
Download the public procurement file (документация за участие), prepare your technical and financial proposal in line with the stated requirements, and submit through CAIS with a qualified electronic signature before the deadline.
4
Monitor awards and the Public Procurement Register
CAIS and Bulgaria's Public Procurement Register publish award notices, contract values, and supplier names. Reviewing this data helps you understand competitive pricing and buyer activity in your sector.

Search Bulgaria government tenders
Bulgarian procurement is regulated by the Public Procurement Act (Закон за обществените поръчки), which implements EU Directives 2014/24/EU and 2014/25/EU. CAIS at app.eop.bg is the mandatory platform for covered procedures. Contracting authorities include ministries, municipalities, hospitals, universities, state-owned enterprises, and utility operators. Key procurement sectors include construction, infrastructure, healthcare, IT, and education.
Bulgaria's EU membership means EU/EEA suppliers can bid on equal terms with Bulgarian companies. Non-EU suppliers are generally permitted unless a contract-specific restriction applies. Documentation is in Bulgarian; international bidders should plan for translation of key sections and ensure qualification evidence is appropriately certified.
Bulgaria's procurement market spans thousands of contracting authorities, making manual monitoring across the full CAIS database time-intensive. Sell to State indexes Bulgarian procurement notices from CAIS and TED, with plain-English search and saved tender searches with a daily email alert.
