Inside every tender on Mercado Público there is a free tool that many suppliers ignore, and that can make the difference between winning and being left out: the question and answer forum. Not using it is one of the most common mistakes, and also one of the most avoidable. Here is what it is, why it matters and how to use it effectively.

What the question and answer forum is

It is the official space within each tender listing where, during a period defined in the process calendar, suppliers can send questions to the purchasing body about any aspect of the specifications, the requirements or the scope of the purchase. The body is obliged to answer, and those answers are official and binding: they carry the same weight as the specifications themselves. They are also visible to every bidder, not just to whoever asked.

In some cases, the forum answers even amend or clarify the original specifications through formal clarifications or amendments. That is why reading the full forum before bidding is as important as reading the specifications themselves.

Why the forum is a strategic tool

It removes ambiguity: tender specifications, especially in complex processes, are sometimes imprecisely worded on technical requirements, delivery formats or evaluation criteria. Asking narrows the interpretation and lets you prepare a bid on certainties, not assumptions.
Official, free information: the body's answers are public and free. Other suppliers' questions can resolve doubts you had not even identified yet.
It levels the playing field: everyone sees the same answers. There is no privileged information in the formal process: what one asks, everyone learns.
It can change the specifications in your favour: if a requirement seems disproportionate or ambiguous, asking about it formally sometimes leads the body to clarify or soften its interpretation.

How to use it effectively

Read the full specifications first: before asking, make sure the answer is not already in the document. Asking something already explained can look unprofessional, and it also wastes the question period.
Identify what really affects your bid: not every doubt deserves a question. Prioritise those that could change your decision to take part, the price you offer or the documents you must submit.
Ask concrete, specific questions: a well-framed question gets a useful answer. A vague question can get an equally vague answer. Cite the paragraph or section of the specifications that gives rise to your doubt.
Respect the question deadline: every tender has a calendar with the exact date and time when the consultation period closes. After that moment, you cannot send further questions. Act in good time, not on the last day.
Re-read the answers before preparing your bid: if the body answered other suppliers' questions during the period, those answers are part of the process and may change something you had already settled.

The cost of not asking

Many suppliers prefer "not to draw attention" or assume that asking shows insecurity. It is the other way round. Not asking and relying on a mistaken reading of the specifications can mean that:

Your bid is ruled inadmissible for failing a requirement you interpreted differently from what the body expected.
You submit documents in the wrong format, which can leave you out even if your proposal is technically good.
You price it wrongly because you were not clear on the real scope of what is being asked.

Asking in the forum is not a sign of weakness: it is the sign of a serious bidder who wants to answer exactly what the body needs.

A practical example

Imagine the specifications ask for "demonstrated experience in similar projects" without specifying how many years or which documents count as evidence. If you assume a reference letter is enough and the body expected formalised contracts, your bid may be poorly scored. One question in the forum —"which documents are accepted as evidence of experience and what is the minimum expected?"— resolves that doubt in days and lets you prepare exactly what the process requires.

In short

The question and answer forum is official, free and strategic information. Always read it before preparing your bid, use the period to ask the questions that really affect your proposal, and review the answers given to everyone else. It is one of the most underused tools in the public procurement system, and also one of the simplest ways to improve your chances of being awarded.
