Licitação: How Public Contracting Works

Whenever the government needs to buy materials, carry out a construction project, or hire a service, it does not simply pick a supplier on its own. Before spending everyone’s money, the administration must open a formal, competitive, and transparent procedure that secures the best deal for the community and treats all interested parties equally. That procedure is the public bidding process, known in Brazil as the licitação.
What the licitação is
The licitação is the procedure through which the public administration selects the most advantageous proposal before entering into a contract. Instead of an official choosing directly who will supply the goods or provide the service, the administration invites interested parties, sets out clear rules in a bidding notice (edital), and selects the winner based on objective criteria that everyone knows in advance.
The core idea is simple. The money that pays for the purchase does not belong to the administrator. It belongs to society. For that reason, the choice of contractor cannot depend on personal preference, friendship, or convenience of the moment. It must follow a path that is open, verifiable, and subject to oversight.
In Brazil, this subject is governed mainly by Law 14.133/2021, the new Public Procurement and Administrative Contracts Law, which has gradually replaced the former Law 8.666/93. The law details the bidding methods, judging criteria, deadlines, and guarantees, always aiming to balance two values: achieving the best result for the government and ensuring equal treatment for participants.
It is worth clearing up a common misunderstanding. Bidding does not simply mean choosing the lowest price. The most advantageous proposal takes price into account, but also quality, delivery time, technical capacity, and sustainability, depending on the judging criterion adopted in the notice. The goal is the best overall package, not just the lowest number.
Why the government is required to use public bidding
The duty to hold a public bidding process is not an administrative choice. It is a constitutional obligation. Article 37, item XXI, of the Constitution requires that public works, services, purchases, and sales by the administration be contracted through a public bidding process, except in the cases the law itself specifies.
This requirement protects interests that go far beyond the purchase itself. It prevents public money from being steered to suppliers chosen through favoritism, safeguards free competition among companies, and ensures that any interested party that meets the requirements can compete for the contract on equal terms.
When the administration holds a bidding process, it also submits to oversight. The procedure generates documents, minutes, and written justifications that can be reviewed by the courts of accounts, the Public Prosecutor’s Office (Ministério Público), and the public itself. This traceability is one of the strongest defenses against waste and the diversion of funds.
The law provides for exceptions, such as waiver (dispensa) and non-requirement (inexigibilidade) of bidding, which apply to specific situations, for example genuine emergencies or cases where competition is not feasible because only one supplier is able to meet the need. Even in those cases, however, a direct contract must be formally justified and documented, or the official may be held liable.
Bidding is not an obstacle to the administration: it is the guarantee that everyone’s money is spent on whoever offers the best result, not on whoever offers the best personal connection.
For that reason, the choice of contractor cannot depend on personal preference, friendship, or convenience of the moment.
The principles that govern public contracting
Public contracting is guided by principles that work as a compass for everything an official does. Some already appear in the caput of Article 37 of the Constitution and apply to the administration in general: legality, impersonality, morality, publicity, and efficiency. Law 14.133/2021 reinforces and expands this list in its Article 5.
Legality means the administration may do only what the law authorizes. In public bidding, this means every stage, deadline, and requirement must have a basis in the law, with no improvisation and no invented rules that harm participants.
Impersonality rules out favoritism and persecution. The bidding notice must be written neutrally, without clauses tailored to benefit a specific company or to shut out legitimate competitors. Everyone competes on the same terms, and the decision turns on the proposal, not on the identity of whoever submits it.
Morality and administrative probity require honest and upright conduct from public officials. It is not enough to follow the bare letter of the rule: officials must act in good faith, with loyalty and integrity, avoiding any maneuver that betrays the trust placed in the administration.
Publicity guarantees transparency. Notices, results, and contracts must be made public so that any interested party can follow the process, raise questions, and, if necessary, challenge it. Secrecy is a strict exception, limited to the contents of the proposals until the proper time for opening them.
Efficiency demands the best possible use of resources. It is not only about spending little, but about getting the best balance between cost and benefit, with proper planning of the contract and attention to the result the administration intends to achieve.
Added to these are objective judgment, which requires clear and measurable criteria, and adherence to the bidding notice (vinculação ao instrumento convocatório), under which both the administration and the participants are bound by the rules of the notice. Once the competition has begun, no one may change the conditions to favor a competitor.
How the bidding process works in practice
In practice, a bidding process begins long before the competition opens. The internal phase, also called the preparatory phase, is where the administration plans the contract: it defines the subject matter, estimates the value through price research, prepares the terms of reference, and drafts the notice with all requirements and criteria.
This planning is decisive. A poorly drafted notice, with disproportionate requirements or a badly described subject matter, tends to lead to challenges, delays, and even annulment of the process. That is why good public contracting comes from serious technical study, not from haste.
Next comes the external phase, when the notice is published and interested parties submit their proposals. The law provides for different bidding methods and competition formats, and the pregão (a reverse-auction-style procedure), especially in its electronic form, has become the most common route for buying standard goods and services because of its speed and broad competition.
Once the competition ends, the administration evaluates the proposals according to the chosen criterion, checks the winner’s qualification documents, ratifies the result, and finally signs the contract. Each of these stages is documented, which allows for review and oversight.
For anyone who wants to contract with the government, the advice is straightforward: read the entire notice, strictly meet the qualification requirements, keep the company’s documentation up to date, and submit proposals that are feasible. Formal errors and unworkable proposals are the most frequent causes of disqualification.
When an abusive clause, a restrictive requirement, or a decision that contradicts the notice itself arises, the participant is not left without recourse. The law provides for requests for clarification, challenges, and administrative appeals, as well as the possibility of going to court. These are legitimate ways to correct illegalities and protect the integrity of the process.
Frequently Asked Questions
Does every government contract require a public bidding process?
The rule is to hold a bidding process, as the Constitution requires. There are, however, exceptions provided by law, such as waiver and non-requirement of bidding, which apply to specific situations, for example genuine emergencies or cases where competition is not feasible. Even then, a direct contract must be justified in writing and documented, or the official may be held liable.
Does the bidding process always select the lowest price?
No. The goal is the most advantageous proposal, which does not always mean the lowest amount. Besides the lowest-price criterion, the law allows proposals to be judged by best technical quality, technique and price combined, highest discount, or greatest economic return, depending on the subject matter. The notice sets out, before the competition begins, which criterion will govern the judging in that particular process.
Can a small business take part in public bidding?
Yes, and the law encourages it. Microenterprises and small businesses receive favorable treatment, such as preference in the event of a tie and the chance to correct tax clearance certificates within a specific deadline. The way to proceed is to follow official publications, read the notice carefully, and keep the company’s documentation organized and current.
