A small contractor's expensive mistake is not bidding too low. It is spending a full day pricing a public contract and then failing on something that was in the notice all along — a bond that takes two weeks to arrange, an insurance limit above the policy in the drawer, a clarification window that closed on Tuesday.
The go/no-go is a paperwork decision, and it is answerable in ten minutes before any estimating time is spent.
Two deadlines, not one. The submission deadline is the one everyone reads. The deadline for clarification questions is usually earlier, and once it passes, anything ambiguous in the scope stays ambiguous and becomes your risk.
Bonds. A bid bond, performance bond, or payment bond is a relationship with a surety, not a form. If you do not already have a facility, "we need one by Friday" is frequently the end of the conversation.
Insurance limits. Not whether you have cover — whether your limits meet the stated minimums, and whether the buyer must be named as an additional insured.
Licences and certifications. Trade licences, registrations, quality or safety certifications, and any prequalification scheme the buyer requires membership of.
Addenda and mandatory site visits. An unacknowledged addendum voids bids on many public contracts, and a mandatory pre-bid visit that has already taken place cannot be recovered.
The submission channel. Portal upload, sealed hard copy, or email to a named address, and whose clock the deadline runs on. A compliant bid delivered the wrong way is a non-compliant bid.
How to use the checker
Paste the notice text into the tool. Nothing is uploaded — the check runs in your browser.
Select Check readiness. Each finding keeps a short excerpt of the text it matched.
Open the source document at each excerpt and confirm it. The excerpt is a pointer, not a finding of fact.
Turn anything you cannot satisfy in the time available into a no-go, and stop there.
The checker is deliberately heuristic. It does not fetch portals, upload text, judge eligibility, or submit anything.
Why "no" is a result worth ten minutes
A contractor who prices four tenders a month and wins one has spent three days on losses. Filtering out the two that were never winnable on paperwork returns two of those days to work that pays — and leaves more time for the one bid that was genuinely worth the effort.
Common questions
Should I bid on this tender?
Decide the paperwork question before the pricing question. Read the notice for the submission deadline and the separate — usually earlier — deadline for clarification questions, then for bonds, insurance limits, licences or certifications, and the exact channel the bid must arrive through. If any of those is something you cannot satisfy in the time available, the bid is a no-go regardless of how well the work suits you, and you have saved a day of estimating.
What disqualifies a small contractor most often?
Administrative failures rather than price: a bid bond or performance bond the contractor cannot obtain at short notice, insurance limits below the stated minimum, a missing licence or certification, a mandatory site visit that has already happened, an unanswered addendum, or a submission sent through the wrong channel or arriving after the stated clock. These are all knowable from the notice before any estimating time is spent.
Does this tool decide whether I am eligible?
No. It is a deterministic text checker that highlights common signals and keeps a short evidence excerpt for each one so you can return to the source. A phrase it did not find is not proof the requirement is absent, and a phrase it did find is not proof your business qualifies. Read the original tender, every attachment, and every addendum before deciding.
