TED (Tenders Electronic Daily) is the EU’s official public procurement journal. It is a strong starting point for larger opportunities and cross-border searches because authorities publish notices there when EU publication rules apply.
Tenderlyzer also covers 13 national registers: ÚVO, NIPEZ/NEN, USP, EKR, BZP, BOAMP, oeffentlichevergabe.de, PLACSP, IUB, ANAC, TenderNed, Simap, and UK Find a Tender. They publish country-specific notices, including opportunities below EU publication thresholds.
Start with TED for broad EU coverage. Add national registers for the countries where you can deliver. A search or Daily task can use your selected registers, while each result still links to its official source.
