One procurement, several notices
Why the same tender is shown once even though several portals published it, and why lots appear as a series.
Two situations make a result list look like it contains duplicates. They look similar and are handled differently, because only one of them really is a duplicate.
The same procurement on several portals
Above the EU thresholds a national notice is also published on TED. The German Bekanntmachungsservice and TED then carry the same procurement, in slightly different words, with different ids. The same happens when a portal republishes a notice after a correction: a new document, same procurement.
Polytender groups these and shows one entry for the group. The list stays readable and a search does not return the same work three times.
On the detail page you see the other notices of the group as a timeline, with their source and stage. That is often more useful than the grouping itself: it shows the procurement from the prior information through the call to the award.
Lots: one procurement published as several notices
A framework split into twelve lots is often published as twelve separate notices. These are not duplicates: each lot is bid for separately, has its own deadline and its own documents.
We therefore never merge them. Instead they are labelled as a series ("Lot 3 of 12") so you can see at a glance that they belong together, and you can still open, bid on and bookmark each lot on its own.
What this means in practice
- A count of results counts procurements, not published documents.
- If you deliberately want every published document, open the timeline on the detail page.
- If a tender looks like it is missing from a list, it may be grouped under a sibling notice from another portal. Searching by buyer or reference number finds it.
