What the service is
BidIndex is a web application operated by Core Engineering Kft. (Váci út 99., 1139 Budapest, Hungary, coreeng.eu). What it does: ingest records from public procurement portals (TED and national platforms), verified private-sector feeds, and the trade press; make them filterable; and deliver them as notifications.
Source data belongs to its original owners. We provide the ingestion, search, translation, and notification layers.
Account and subscription
Registration is free; access to tender and job records and to AI analyses requires a subscription. There is no free tier. Without a subscription the homepage showcase, aggregate statistics and Guide articles are available; signing in with a free account also opens the news feed.
Sales and invoicing are handled by Paddle.com Market Ltd. Paddle is the merchant of record for these sales: your payment contract is with Paddle, Paddle issues the invoice, and Paddle appears on your card statement. The service itself is provided by Core Engineering Kft., which remains responsible for its content.
Published prices exclude VAT. Tax is added at checkout by Paddle based on your country; if you enter a valid EU VAT number, the reverse-charge rule applies.
Subscriptions are charged in advance at the published price (monthly or annually) and renew automatically until cancelled. The current price is always shown on the pricing page.
Credit packs are one-off purchases and are generally non-refundable; your statutory right of withdrawal as a consumer remains unaffected (see /legal/withdrawal). Purchased credits never expire; the monthly subscription allowance resets at the end of each month.
Cancellation: you can cancel at any time from your account page. Cancellation takes effect at the end of the paid period and that period is not refunded; your statutory right of withdrawal is not affected.
Right of withdrawal: if you subscribed as a consumer you may withdraw within 14 days without giving a reason and get your money back (EU Directive 2011/83). The right ends only if you expressly asked us to start the service before the period was up and acknowledged that you would lose it — details and model form: /legal/withdrawal
You are responsible for the security of your account. On suspicious access, change your password immediately and tell us.
You may delete your account at any time from your account page; all data except accounting records subject to statutory retention is removed (details: /legal/privacy).
Acceptable use
Do not bulk-download or scrape the service with automated tools, and do not call the API at volumes beyond normal use of the interface. We apply technical rate limits to protect the service; they may change when needed.
Do not share your access with third parties; an account is for one user. Contact us for team access.
Do not use the service unlawfully or in a way that degrades it for others.
Accuracy of content
Tender records are ingested automatically from public sources and may be machine-translated. Errors or delays at the source propagate to us.
Always verify the original notice (TED or the relevant national platform) before bidding. Your decision must rest on the original notice.
AI summaries and matches are assistive; they can be wrong and do not replace legal assessment.
BidIndex is not legal advice. Consult your lawyer or procurement advisor on regulatory matters.
Limitation of liability
Core Engineering Kft. does not warrant that the service will be uninterrupted or error-free, and is not responsible for the availability of upstream sources.
To the maximum extent permitted by law we exclude liability for missed tenders, lost profit, and indirect damages. For direct damages, liability is capped at the subscription fees you paid in the 12 months before the claim arose.
This does not limit liability for intent or gross negligence, nor your statutory consumer rights.
Intellectual property
The BidIndex name, interface, and software belong to Core Engineering Kft.
Tender data belongs to its sources: TED and the EU Open Data portal are openly licensed, national sources are under their own licences.
Some news feed records come from the GDELT Project; GDELT metadata is licensed under CC BY 4.0 and credited. The news articles themselves belong to their publishers: only the headline, a short summary and a link to the original article are shown.
You may not reverse engineer, clone, or bulk-republish the dataset.
Suspension and termination
We may suspend accounts that breach these terms after warning; for severe breaches, without warning. Remaining subscription time on a suspended account is not refunded.
If we discontinue the service we will give 30 days' notice by email, provide a data export, and refund any prepaid unused period.
Changes to these terms
We may update these terms. For material changes to your disadvantage we give at least 30 days' notice by email; if you do not accept them you may cancel free of charge before they take effect.
Version of these terms: 2026-09-15.2. The version you accepted at sign-up and the time of acceptance are stored with your account.
Governing law and disputes
These terms are governed by Hungarian law; the courts of Budapest, Magyarország have jurisdiction.
If you subscribed as a consumer, the mandatory consumer protection rules of your own country and your right to bring proceedings there remain unaffected.
The bodies you can turn to in consumer disputes are listed on the legal notice page: /legal/imprint
