The essentials in 30 seconds

  • A bid submission file mixes two families of documents: the administrative ones (which prove you have the right to contract) and the offer documents (your price and your proposal).
  • Many rejections come from an administrative document that's missing, expired or improperly signed, not from the quality of the offer.
  • Every call for tenders has its own list: the specifications govern. This article gives you the most common documents so you can prepare yours in advance.

Mathieu spent two days polishing his price and his technical proposal. His bid is rejected: an attestation was missing, and another had expired by a few days. It's the most ordinary and the most avoidable story in public procurement. A bid is won as much on documentary rigour as on the offer itself. The documents a public call for tenders can require are prepared before the rush, not in a scramble.

Warning

The list that governs is the one in the specifications (cahier des charges). Every call for tenders sets its own requirements. This article rounds up the most frequent documents to help you anticipate; it doesn't replace a careful read of the file, where an unusual document may be required.

Two families of documents

Every bid submission file falls into two categories:

  • Administrative documents prove that you're a business in good standing, authorized to contract with the State. They're the ones that determine the eligibility and compliance of your bid.
  • Offer documents carry your proposal: the price schedule, and depending on the award method, your technical proposal (methodology, team, references).

The first get you rejected when they're missing; the second win you the contract when they're strong. You need both.

The most frequent administrative documents

Let's detail the three that cause the most rejections.

The attestation from Revenu Québec: watch its validity

It's one of the most ordinary and most treacherous documents. The problem isn't getting it (you request it online through Mon dossier de Revenu Québec and can submit it immediately), but its validity period: it's valid until the end of the month it was issued and for the three months that follow, and it must not have been issued after the deadline date and time for receiving bids. If it's expired at submission, the bid can be rejected: depending on the specifications, the body may not allow it to be corrected after submission.

Tip

The reflex: check the validity date of your attestation before every submission, not once a quarter. When in doubt, request a fresh one: it's free. An attestation expired by a few days brings down an otherwise excellent bid.

Bid security: when it's required

Some calls for tenders (often in construction) require a bid guarantee, which assures the body that you'll honour your offer if you're selected. It frequently represents on the order of 10% of the bid value (but the exact amount is the one in the specifications) and is obtained from an authorized financial institution, often through a surety broker. Since issuance takes time, you need to start before the closing date. We detail the amounts, timelines and steps in the article dedicated to bid security.

Signatures: by the right person

A form signed by someone without the power to bind the business can lead to rejection. Check who, in your company, is officially authorized to sign a bid, and make sure it's that person who signs, in the right place, on every document that requires it.

The offer documents

Once eligibility is secured, come the documents that carry your proposal:

  • The price schedule, filled out exactly according to the imposed format.
  • The technical proposal, when the contract is awarded on a quality-price basis: methodology, schedule, team composition.
  • References and proof of experience, when they're requested as criteria.

The weight of these documents depends entirely on the award method: with lowest compliant price, only the compliant price counts; with quality-price, your technical proposal counts toward the score. That's why you should always identify the method before calibrating your effort, a point we cover in the guide how to bid on a public tender.

Build a core of reusable documents

A large share of these documents is prepared once and reused. Put together an up-to-date base file (registration, attestations, insurance, licences, company descriptions, standard references) that you adapt to each call for tenders rather than redoing everything under pressure. It's exactly what separates a beginner tenderer from an efficient one, as we explain in the article on how to bid without experience.

What to remember

A complete bid submission file is two families of documents: the administrative ones, which make you eligible, and the offer ones, which win you the contract. Rejections often come from the first: an expired attestation, a missing bid security, an unauthorized signature. Prepare a core of reusable documents, check the validity of your documents before every submission, and rely on the exact list in the specifications, which remains the only one that really counts. It's the most avoidable part of failure in a call for tenders.
