TenderWolf aggregates public tenders from multiple European sources into a single searchable platform. In this article, we describe which sources we cover, how quickly publications become available, what we do with the data, and how our matching and AI analysis work.

Sources

TenderWolf retrieves publications from the following official sources:

Belgium — e-Procurement (e-Notification)

The Belgian federal publication platform, managed by the Federal Public Service Policy and Support (BOSA). All Belgian public tenders above €30,000 (excl. VAT) are published here. This includes tenders from federal, regional, provincial, and municipal authorities, as well as utilities and other contracting bodies.

TenderWolf processes all publication types: contract notices, contract award notices, corrigenda, and simplified notices.

Netherlands — TenderNed

The Dutch publication platform, managed by the Ministry of Economic Affairs. Mandatory for all Dutch contracting authorities above European thresholds, and widely used for contracts below those thresholds. TenderWolf processes all public notices.

Luxembourg

Publications from Luxembourg’s government are processed through the national portal and via TED.

France — BOAMP

The Bulletin Officiel des Annonces de Marchés Publics, France’s official publication bulletin for public tenders. Covers most French government tenders, both above and below European thresholds.

Europe — TED (Tenders Electronic Daily)

The European supplement to the Official Journal of the EU, managed by the Publications Office of the European Union. All above-threshold European tenders are published here — regardless of country of origin. TenderWolf processes publications from all EU member states and the EEA.

TED is the source for tenders above European thresholds (as of 2024: €143,000 for supplies and services to central government, €221,000 for sub-central government, €5,538,000 for works). Below-threshold tenders only appear on national portals.

Processing speed

New publications are processed and made available in TenderWolf the same day. Exact timing depends on when the source publishes:

e-Procurement: publications appear throughout the day; TenderWolf processes them continuously.
TenderNed: daily processing.
TED: publications typically appear in the morning; processed the same day.
BOAMP: daily processing.

Daily email alerts are sent in the morning and contain all publications processed since the previous alert.

What we process

Per publication, TenderWolf processes the following data:

From the structured notice: title, description, contracting authority, CPV codes, NUTS regions, procedure type, estimated value, deadlines, lots, award criteria, contact details, and all other fields completed by the authority.

From attachments (specifications and tender documents): the full text is indexed and made searchable. This matters because much critical information — detailed selection criteria, technical specifications, award criteria with weightings — only appears in the specification, not in the notice.

From award and opening documents: for open procedures, opening reports (with submitted prices) and award decisions are processed when available.

Matching: how search profiles work

A search profile in TenderWolf combines up to six dimensions, all with AND logic (a publication must match all configured dimensions):

Keywords — per line, with fuzzy matching. Searches title, description, and full specification text. Spaces act as AND, quotes for exact match, OR for alternatives, minus sign for exclusion.
CPV codes — hierarchical. You can select a main category and include or exclude all subcodes. For example: 72000000 (IT services) including all subcodes, but excluding 72500000 (computer maintenance).
NUTS codes — from country level to municipality level. Include/exclude subcodes. You can also search within a radius around an address.
Contractor classifications (construction sector) — category and class. Relevant for Belgian works tenders, where contractor classification is legally required.
Form types — open procedure, restricted procedure, competitive procedure with negotiation, competitive dialogue, framework agreements (separately filterable).
Contracting authorities — select specific authorities to follow.

There is no limit on the number of search profiles, even on the Free plan.

AI matching

In addition to rule-based search profiles, TenderWolf learns from your feedback. When you approve or reject publications, the system uses that pattern to improve the relevance of future publications. This works as a complement to — not a replacement for — your search profiles.

AI Quickscan: how specification analysis works

The AI Quickscan analyses the full text of a specification and extracts structured information:

Subject: what exactly is being requested?
Keywords: key terms from the specification
Procedure: which procedure type is being followed?
Estimated value: if stated or derivable
Selection criteria: required turnover, references, certifications, classifications
Technical standards: specifically required standards or certificates
Award criteria: with weightings (price x%, quality y%, etc.)
References: required type and number of comparable contracts
Tender potential: indication of likelihood based on your profile
Site visit: whether a mandatory site visit is required

The output is designed to accelerate your GO/NO GO decision — not to replace the specification. When in doubt, always consult the full document.

Company profiles and market insight

TenderWolf builds company profiles based on publicly available data:

Tender history: won and lost tenders, based on published award decisions
Financial data: revenue, gross margin, profit, FTEs, financial ratios — based on filed annual accounts
Competitors: ranked by intensity (how often they’re active with the same authorities)
Opening reports: submitted prices in open procedures

All this data comes from public sources: the Belgian Official Gazette, the Crossroads Bank for Enterprises, the Central Balance Sheet Office (NBB), and the publication portals themselves.

What we don’t do

Transparency also means stating what we don’t do:

No non-public data: we exclusively process publicly published information. We have no access to contracting authorities’ internal documents.
No guaranteed completeness: we aim for complete coverage of official sources, but if an authority places a publication after business hours, it may in exceptional cases be available with a one-day delay.
No legal advice: the AI Quickscan and company profiles are tools, not replacements for your own analysis or legal counsel.
