Every public tender is published free somewhere. There are four source types worth knowing: national procurement portals, which carry the widest range including small local contracts; supranational journals such as TED, which carry higher-value notices; open data feeds and bulk downloads, which let you pull notices programmatically; and award notices, which show what has already been bought. Access costs nothing. What it costs is your time, and that is the whole trade-off.
If you want the general method — filtering, qualifying, deciding — start with how to find government tenders. This article is about the sources themselves.
1. National procurement portals
This is where most opportunities actually live. Public buyers are required to advertise contracts above certain values, and each country runs an official platform where those notices appear: Find a Tender and Contracts Finder in the United Kingdom, riigihanked in Estonia, BOAMP and PLACE in France, TED eTendering and national systems elsewhere, simap in Switzerland, Doffin in Norway, and equivalents in every market with a formal procurement regime.
Portals are the only place many smaller contracts appear at all, which matters because below-threshold work is often the most winnable for an SME. Their weaknesses are practical rather than legal: notices are in the local language, the search tools range from decent to unusable, alert systems are inconsistent, and each portal is a separate account, a separate login, and a separate habit to maintain.
Do this: identify the national portal for every market you sell into, register on each, and set up whatever alert facility it offers. Registration is free and is often required to download documents anyway.
2. Supranational journals
Contracts above the applicable procurement thresholds must be advertised more widely — in the EU that means TED, which aggregates higher-value notices from all member states in one searchable place with a usable API and bulk downloads.
The limitation is structural rather than a flaw: journals of this kind carry above-threshold notices, so the large volume of smaller local contracts simply is not there. Relying on TED alone gives you the biggest contracts and the most international competition, which is often the least favourable combination for a smaller supplier.
3. Open data feeds and bulk downloads
A growing number of systems publish machine-readable data — commonly in the Open Contracting Data Standard — as an API or a daily archive. If you have any technical capacity, this is the most efficient free route: you can filter, store, and analyse without touching a web interface.
Two caveats. Field coverage varies, so a value or a deadline present in one country's feed may be missing in another's. And feeds usually carry the notice, not the tender documents, which frequently still require a portal login. Before you build anything on top of them, read what a build actually involves — the ingestion is the easy part.
4. Award notices and buyer pipelines
Two sources are consistently underused because they are not open opportunities.
Contract award notices tell you who won, at what price, and how long the contract runs. That is your re-tender calendar: a three-year contract awarded today is a competition you can prepare for two and a half years from now, long before it appears as an opportunity. It is also how you find prime contractors to approach about subcontracting.
Prior information notices and published procurement plans do the same thing in the other direction — they signal what a buyer intends to tender before the formal notice exists, which is the only moment you can influence a specification legitimately by engaging in pre-market dialogue.
5. Buyer websites and direct relationships
Large authorities publish forward plans, run supplier events, and maintain "selling to us" pages that describe their process and their below-threshold routes. For contracts under the advertising thresholds, being on the right list is often how you get invited to quote at all. This does not scale, but for the ten buyers who matter most to you it is high-value and free.
What free actually costs
None of the above is hard individually. The cost is that it is a daily routine across multiple systems, in multiple languages, in whatever taxonomy each portal uses, with no ranking to tell you which of today's forty notices is worth reading. The Tendly data snapshot counts more than 50,000 active tenders across 23 countries — and more than a quarter of them are closing within seven days. Manual scanning misses things not because it is careless but because the window is short.
The practical test is whether your discovery routine survives a busy month. If your best month for delivery is your worst month for finding opportunities, the routine has already failed.
A weekly routine you can actually keep
If you are staying with free sources, make the routine small enough to survive. Once a week, work through your national portals in a fixed order and triage new notices into pursue, watch, or discard — decisions, not reading. Once a month, review award notices in your categories to see who is winning and when contracts come up again. Once a quarter, revisit your saved searches and code lists, because what you sell drifts faster than your filters do.
Give each portal a named owner and a fixed slot in the calendar. The routine fails in the same way every time: not through carelessness, but because the week the delivery team is busiest is also the week nobody checks.
When aggregation earns its cost
Paying for aggregation makes sense at a specific point: when you sell into more than one country, when you have lost something you would have won by finding it too late, or when nobody can say what is currently open to you. What you are buying is one searchable dataset instead of many, ranking with reasons attached, cross-language search, and monitoring for changes after publication — described in more detail in what tender intelligence software is.
Either way, get your CPV code list right first — it is the filter that makes every one of these sources usable. You can browse live tenders by country and category to see what your codes would be returning today.
