Version 2. A month's figures are computed once, from the 5th of the next month (Türkiye time), after every source of the month was read whole, and never change afterwards.
What it measures
How much public buying was announced in Türkiye in a month, and what Birlesa did with it: the direct procurement calls and tender notices published in the sources Birlesa reads, for the country and for each of the 81 provinces, with the matches Birlesa published to companies and the companies its directory lists. The month's national report also carries Türkiye's exports of the month as TİM registered them.
What is counted
- Direct procurement calls and tender notices. Every notice published in the month (by its publication day in Türkiye) in the sources below. The province is the notice's own; a notice that names no province counts for the country only.
- By kind. EKAP's direct procurement calls (doğrudan temin, article 22 of Law 4734 and its exceptions), and the tender notices public bodies publish on their own pages.
- By sector group. A notice counts in each of the site's sector groups its items fall in, by the activity codes that make them. A notice whose items could not be placed is in no group; a notice in two groups counts in both, so the groups do not add up to the total.
- Public bodies. The distinct authorities that published at least one notice in the month.
- Matches. The matches Birlesa published to companies in the month, for the country and by the matched company's province.
- Companies listed. The companies in Birlesa's directory on the day the month is frozen, for the country and by province. Counted from the first month frozen under version 2.
- Exports. TİM's export registrations of the month, with the month before, the same month a year before, the largest sectors and the markets Birlesa's export panel follows. Read from TİM's monthly tables as published, with the table's name and release date on the page. They are registrations through the exporters' associations, not the Ministry of Trade's general trade figures.
Where the notices come from
| Source | What is read |
|---|---|
| EKAP (Public Procurement Authority) | Direct procurement calls only |
| Public bodies' own tender pages | Their tender notices (for example BOTAŞ, TEİAŞ, TKİ, Türkşeker and İzmir Metropolitan Municipality) |
Each month's report lists the sources of that month with the number of notices each published.
What is not counted
- EKAP's tenders. Open tenders and the other tender procedures on EKAP are not read. The figure is therefore not the number of all public tenders in Türkiye, and must not be quoted as such.
- Companies founded and closed. Trade registry and court notices are not collected, so no such figure is published.
- Anything estimated. A figure no source states is absent; nothing is modelled or filled in.
When a month is frozen
- From the 5th of the next month, the month is frozen on the first day every source of its notices has been read whole since the month ended.
- On the 10th the month is frozen as it is. Each source still not read whole is named on the month's page, and the month is not offered to search engines.
- A frozen figure never changes. Notices that change at their source later do not move it.
Comparisons
- Month before and same month last year. Shown only when that month was released and counted the same figure. A column with no value is not drawn.
- Change. The percentage on the month before is given only when that month's figure is 10 or more; under it, the two numbers are shown.
- Share and rank. A province's share of the country's notices, and its rank among the provinces with a notice in the month.
Which pages are offered to search engines
A month's report is offered when its sources were read whole and it holds at least three figures other than zero. A province's page is offered when its month is, it shows at least four figures with a value, each of them has its previous month, and at least one has its month a year before. Every other page stays readable and is marked for search engines as not to be indexed.
Summaries
The sentences at the top of each page are written from fixed templates filled with the stored figures. No language model writes or rewrites them.
Changes to this method
- Version 2 (from the release of November 2026). Adds the kinds, the sector groups, the public bodies, the matches by province and the companies listed; freezes a month only once its sources were read whole (version 1 froze on the 3rd whatever had been read). The definitions of version 1's two figures, the notices and the matches, did not change, so they are compared across the two versions.
- October 2026. Released under version 1. Version 2's figures were added to it afterwards, counted from the notices loaded before its release, so they stand under the totals it froze; nothing it froze was changed. Where notices changed at their source after the release, the split by kind covers fewer notices than the frozen total, and the page says by how many.
- Version 1 (October 2026). The notices and the matches for the country, and the notices by province.
Any change gets a new version number, is described here, and applies from the next computed month; a published month keeps the figures it froze.
