Methodology, sources & data freshness

Where the data comes from

Only official, publicly available tender and contract-award notices published by public buyers, governments and international financing institutions under open-data licences. Every record shows its official notice link and the licence attribution the publisher requires. Licence texts: Data licences.

How we process it

1. Collect: notices are fetched daily from official open-data interfaces; the official notice link is kept on every page.
2. Classify: procurement codes and keyword rules map each notice to 15 categories and 13 product groups. A notice can be in more than one group.
3. Duplicates: the same tender published in more than one place is shown once.
4. Open / awarded: a tender counts as “open” if its deadline is today or later at build time, or if the notice gives no deadline (check the notice).
5. Values: shown only where the buyer published one; EUR conversion is approximate (ECB rate of 30 Oct 2026).
6. Turkish summary: generated automatically from structured fields – not a translation of the notice text. The official notice prevails.
7. Winner profiles: built only for names that are clearly companies. Individuals and masked names never get a page.
8. Tender breakdowns: item lists come from the public tender files linked on each page; product groups, export-fit flags and supplier types are our assessment.
