A public tender is two competitions running at once. The first is the one everyone prepares for: scope, method, price. The second is administrative, and it is decided before anyone opens your pricing envelope. Fail it and your number is never read. That second competition is where most losses actually happen. The pattern is consistent across owners and jurisdictions: the bid was competitive, the team knew the work, and a form was missing. ## 1. The addendum acknowledgement Addenda are the single most common cause of a rejected bid, and the reason is structural rather than careless. Addenda arrive late, often in the final week, sometimes hours before close. Each one usually has to be acknowledged explicitly — by number, on a specific form — and a bid that acknowledges three of four addenda is frequently deemed non-compliant on its face. The trap is that addenda do two things at once. They change the work, and they change the paperwork. A team can correctly price an addendum's scope change and still fail to sign the page that says they received it. Track addenda by number, not by "we got them all." Confirm the count on the portal the morning of submission, not the week before. ## 2. The bid bond or security Bid security fails in narrow, specific ways: the wrong amount, the wrong form, the wrong validity period, an unsealed surety, or a digital bond the owner does not accept. The amount is usually a percentage of the bid value, which means it cannot be finalized until the price is — and so it lands in the last hour, when there is the least room to fix it. Check three things independently: the percentage, the validity window against the stated bid acceptance period, and the format the owner will accept. ## 3. Proof of qualification and licensing Contractor licences, trade qualifications, and registrations all expire, and they rarely expire conveniently. A licence that was valid when the tender was issued may not be valid at close, and the owner cares about the date on the certificate, not the date you downloaded it. In Quebec, an RBQ licence in the correct subcategory is a threshold requirement, and the subcategory matters as much as the licence itself. In the United States, state-level licensing and registration requirements vary enough that a firm bidding across state lines needs to verify per tender rather than per year. ## 4. Insurance certificates with the right named insured Insurance is rejected less often for insufficient coverage than for naming the wrong entity. The certificate has to name the owner exactly as the tender specifies — including the legal suffix, the department, and any additional insureds — and the coverage has to be in force through the stated period. A certificate that names your company correctly and the owner approximately is a non-compliant certificate. ## 5. Signatures and sealing on the right pages The last one is the most avoidable and the most common: a form signed by someone without signing authority, an unsealed page where a seal was required, an unwitnessed signature, or a form submitted in the wrong format because the tender asked for a scanned wet signature and received a digital one. Electronic submission has not made this go away. It has moved it — from "did we sign it" to "did we sign it in the form the portal accepts." ## The underlying problem None of these five are hard. They are all easy to check individually, and every bid team knows they matter. The difficulty is that the requirements are distributed. They live across the instructions to bidders, the supplementary conditions, four addenda, and an appendix, and each one is written in a different place by a different author. Assembling them into a single list is manual work, and it happens in the last seventy-two hours before close, which is exactly when the team has the least capacity to do it carefully. That is the gap [Offra](https://offra.cc) is built to close: reading the full tender set, extracting every requirement with a reference back to the document it came from, and producing one checklist that shows what is still outstanding — before the deadline, not after the debrief.
