When a company is excluded from a public tender, the first question is almost always “why?”. The answer usually falls into one of two categories — and the difference between them matters more than it seems. It decides whether you ever had a chance, whether an appeal is worth it, and what to change next time.
The two types of grounds
Formal grounds are procedural. A missing document, an expired bank-guarantee validity, an uncertified signature, a mismatch with a template, an incorrectly filled eEEDOP. What they share is that they have nothing to do with your real capacity to perform the contract. A capable company can drop out over a single line in a document.
Substantive grounds are about content. You don’t meet the turnover requirement, you lack the experience for the specific scope, your key expert doesn’t meet the qualification criteria. Here the exclusion reflects an objective mismatch with the tender’s conditions.
Formal losses are “cheap” — preventable yet fatal. Substantive losses are an honest signal that either the tender wasn’t for you, or you needed a consortium or a subcontractor.
Why the distinction decides your strategy
If the reason is formal, the strategy is simple: bid, but flawlessly. These mistakes are almost entirely preventable with a precise check of documents against requirements before submission. This is where most bidders find their biggest quick win — not more bids, but fewer self-inflicted exclusions.
If the reason is substantive, the question is different: does it even make sense to bid alone? Sometimes the answer is a consortium, sometimes a subcontractor who brings the missing experience, and sometimes deliberately skipping this tender in favour of a better fit.
A wrong diagnosis is expensive. Companies appeal a formal exclusion where the requirement was actually lawful and clear — and lose the fee and the time. Or they treat a substantive exclusion as “bad luck” and repeat the same mistake in the next procedure.
How the data helps
Reading a single exclusion decision on its own rarely gives the full picture. The power comes from context: how often a similar ground appears with this contracting authority, how the requirement is worded compared with other procedures, and what the practice shows when similar cases are appealed.
Our base spans more than 205,000 decisions, protocols and reports linked to 84,532 tracked tenders. That lets every exclusion ground be placed in context — formal or substantive, typical or not, and what the historical profile of similar cases looks like. (Exact percentages vary by sector and authority and are computed per tender.)
What to remember
- Always classify the reason first: formal or substantive.
- Formal grounds are solved with precision before submission — the easiest wins.
- Substantive grounds require an honest call: alone, in a consortium, or not at all.
- Context from historical data turns “bad luck” into a manageable risk.
This exact classification underpins our risk assessment and our requirements ↔ documents check — so you stop losing tenders for reasons you could have prevented.
