Can a MEI bid in public tenders? Dos, don'ts and how much it can sell

An individual microentrepreneur (MEI) can bid in public tenders like any other company and even enjoys legal benefits — but runs into the revenue cap and requirements that call for planning. Here is what changes in practice.

Yes, an individual microentrepreneur (MEI) can take part in public tenders (licitações). There is no legal restriction on the MEI in public procurement — quite the opposite: for the purposes of Complementary Law 123/2006 (Small Business Statute), it is classified as a microenterprise and receives the same special treatment benefits, including tie preference and exclusive competition in lower-value purchases.

What does exist are practical limits that must go into your planning before the first bid: the annual revenue cap, the fact that you cannot hire more than one employee, the restricted list of permitted activities and the difficulty of proving economic and financial qualification. This guide goes through each of them and shows the kinds of tenders where a MEI can really compete well.

The legal basis: a MEI is a microenterprise

Article 18-A of Complementary Law 123/2006 defines the MEI as an individual entrepreneur whose revenue stays within the established annual limit and who opts for a fixed monthly tax payment. For public procurement, what matters is Article 3 of the same law: the MEI falls under the concept of a microenterprise, and Chapter V — which deals with special treatment in public tenders — applies to it in full.

Law 14,133/2021 (Brazil's Public Procurement Law) reinforces this in Article 4, by requiring the provisions of Complementary Law 123 to be applied to public contracting. In practice, when a tender notice (edital) refers to "ME/EPP" (micro and small businesses), the MEI is included.

The benefits a MEI has by law

Tie preference: the second chance

If the MEI's bid is up to 5% above the lowest bid submitted by a company that is not an ME or EPP, there is a tie preference (empate ficto). The system calls on the MEI to beat that bid, and if it does, it wins. This is automatic in the electronic reverse auction (pregão eletrônico) and does not need to be requested.

In practice, this means the MEI does not need to be the cheapest during the bidding — it needs to get close. Many suppliers are unaware of this mechanism and stop bidding, thinking they have lost.

Exclusive competition in lower-value purchases

Purchases up to a certain value must be reserved exclusively for micro and small businesses. In these tenders, larger companies cannot even submit a bid. This is the range where a MEI gets the best ratio of effort to chance of winning, and it overlaps with many of the electronic direct awards (dispensas eletrônicas) published every day.

Extra time to fix certificates

MEs, EPPs and MEIs can submit tax documents showing outstanding issues and regularize them after being declared the winner, within the legal deadline, which can be extended. Watch out for a detail that trips up many people: the document must be submitted anyway, even with the outstanding issue. Sending nothing is not the same as sending it with a restriction.

Preference in an actual tie

When bid values are tied, the tiebreak criteria of Law 14,133/2021 favor, among others, small businesses and microenterprises — one more layer of advantage.

The real limits of a MEI in public tenders

1. The revenue cap is the main obstacle

A MEI has an annual gross revenue limit. If the public contract, added to the rest of your revenue, pushes you over that cap, you lose MEI status — with retroactive reclassification and taxes paid as a regular microenterprise, including differences that can hurt.

So before bidding, do the math: how much you have already billed this year, how much the contract will generate and how much you still expect to bill in the private market. A price registration contract, whose price registration record (ata de registro de preços) can last twelve months and be drawn on gradually, calls for extra care — the total value of the record is not immediate revenue, but it can become revenue.

If the size of the opportunity breaks the cap, there are two legitimate routes: bid on only some of the items, or switch to a microenterprise before the competition. Switching is a natural step in growing and does not prevent anything: an ME keeps all the benefits of Complementary Law 123, except the MEI's fixed monthly tax payment.

2. Only one employee

A MEI can have at most one registered employee. That rules out contracts that depend on a team — ongoing cleaning, security guard and administrative support services, or construction work requiring a minimum workforce. For labor-based contracts, a MEI is out in practice, even if it manages to qualify on paper.

3. Permitted activities

Not every economic activity is open to a MEI. Regulated intellectual services — consulting, accounting advice, engineering, architecture, medicine — are not on the list. If the object of the tender requires registration with a professional council, it is probably not a MEI activity. Check the official list of occupations before investing time in the tender notice.

4. Economic and financial qualification

A MEI is exempt from keeping regular accounting books, which is great day to day and bad when you have to prove liquidity ratios or minimum net worth. Larger tender notices usually ask for a balance sheet — and a MEI does not have one. The way out is to choose tenders that do not require it, which is common in low-value purchases, or to have an accountant prepare a balance sheet when the requirement comes up.

Where a MEI really competes well

The combination of a revenue cap, a small team and simplified paperwork points to a clear profile of opportunity:

• Low-value electronic direct awards with short deadlines — less competition and reduced document requirements;
• Supply of products rather than labor: office supplies, cleaning products, kitchen and pantry supplies, foodstuffs, small IT equipment;
• One-off technical services compatible with the list of occupations: maintenance, installation, small repairs, printing services, uniform making;
• Purchases reserved for ME/EPP, where the big players cannot even enter;
• Government agencies in your own city or region, where freight works in your favor and delivery is simple.

A strategy that works: pick two or three nearby agencies that buy what you sell and follow their publications daily. Each agency page shows its purchasing history and frequency, which lets you predict when the next tender notice for the same item will come out.

Documents a MEI needs

The list is shorter than for a regular company, but no item can be skipped:

• MEI Status Certificate (CCMEI), which takes the place of articles of association;
• An up-to-date CNPJ card (Brazilian company tax ID), with an activity that matches the object of the tender;
• Joint federal certificate (Receita Federal and PGFN);
• FGTS certificate of good standing (FGTS is the employee severance fund) — mandatory even without employees;
• CNDT (labor debt clearance certificate), from the Labor Courts;
• State and municipal certificates from where the business is based;
• Declaration of ME status, to trigger the benefits of Complementary Law 123;
• DASN-SIMEI (the MEI's annual revenue declaration) for the last fiscal year, which some tender notices accept as proof of revenue;
• Business permit and health license, when the activity requires them.

One MEI-specific precaution: keep the DAS (the fixed monthly tax payment) up to date. Late payments compromise your certificates and, in the case of prolonged default, can lead to cancellation of the CNPJ — which you find out at the worst possible moment.

Step by step for your first tender

1. Check the CNAE (economic activity code) on your CNPJ card and compare it with the object you intend to bid on;
2. Issue all certificates and build a digital folder that tracks expiry dates;
3. Register on Compras.gov.br (federal e-procurement system) and on the platforms used by the agencies in your region;
4. Search by what you sell, not by agency name — start with the tenders open today;
5. Read the terms of reference and check that the specification exactly matches what you supply;
6. Calculate the price including the DAS, freight, packaging and the time until you get paid;
7. Submit the bid with time to spare and declare your ME status;
8. Take part in the session and use the tie preference to your advantage;
9. Deliver on time and ask the contract inspector for a technical capacity certificate (atestado de capacidade técnica).

A numerical example: the math that keeps you from losing MEI status

Suppose a MEI that provides maintenance services has already billed a certain amount in the private market through August. A price registration tender comes up for building maintenance at municipal schools, with a twelve-month price registration record.

The common mistake is to look at the total value of the record and conclude "it doesn't fit under my cap". The record is an expectation: the agency only pays for what it actually orders, and the supplier is not obliged to accept orders that exceed its capacity — as long as the tender notice addresses this. The right approach is to project three scenarios (low, medium and high demand), add them to your expected private revenue and see in which of them the cap is exceeded.

If it is exceeded only in the high scenario, there are two ways out: bid on only some of the items, or plan to switch to a microenterprise during the year. What must not happen is finding this out in November, with the revenue already booked — reclassification is retroactive to the month in which the excess occurred, and the tax difference is charged.

It is also worth noting the effect of an excess of up to 20%: in that case, reclassification takes effect from the following year, not retroactively. Above that, it is retroactive. Knowing where this line is changes the decision on whether to accept the last supply order of the fiscal year.

MEI or microenterprise: a direct comparison for bidding

The practical takeaway from the table: the MEI is excellent for entering the public market and poor for growing in it. It is good for winning your first contracts, your first certificates and getting familiar with the process — and should be replaced as soon as volume justifies it.

Mistakes that eliminate a MEI before the competition

• Not declaring ME status in the system. Without this declaration, the tie preference is not triggered and the exclusive competition does not apply — the benefit exists, but it is not automatic if the box is not ticked;
• Late DAS payments, compromising the federal certificate the day before the session;
• Bidding on an object outside the permitted occupation, which leads to disqualification for a non-matching CNAE even with the lowest price;
• Accepting a contract that requires a team, which is impossible to perform with one employee;
• Ignoring the cost of the payment term: delivering in September and getting paid in November means financing the customer for two months, and that has to be built into the price;
• Not asking for the technical capacity certificate on completing the delivery — the most valuable asset from your first contract.

Frequently asked questions

Does a MEI need a bankruptcy certificate?

Many tender notices ask for one, and a MEI can obtain it normally from the civil court registry of its judicial district. When the requirement appears, there is no exemption for being a microentrepreneur.

Can a MEI take part in an electronic reverse auction?

Yes, in any procurement method — reverse auction (pregão), direct award (dispensa), competitive bidding (concorrência), auction (leilão). The procurement method does not restrict company size; what restricts it is the capacity to perform the contract.

Can a MEI team up with another company?

A consortium is allowed when the tender notice permits it, but it usually brings requirements that cancel out the MEI's simplicity. In most cases, it is not a very productive route.

How long does it take from tender notice to payment?

Add up the time from publication to the session (usually eight business days), ratification (days to weeks), the issuing of the commitment note (nota de empenho), the delivery period and roughly another thirty days until payment. Plan working capital for two to three months between investing and getting paid.

Is it worth hiring a consultant?

For a MEI just starting out, rarely. The process is public, and the number of matching tender notices is small enough to follow on your own in a few minutes a day. A consultant makes sense when volume grows and the bottleneck becomes time, not knowledge.

When it is worth leaving MEI status behind

If you have started winning tenders regularly, the revenue cap becomes the limiting factor for the business. Switching to a microenterprise keeps all the benefits in public tenders — tie preference, exclusive competition, extra time to fix certificates — and removes the low cap, the one-employee restriction and the limits on activities.

The cost is regular accounting and a tax burden that varies with revenue instead of being fixed. For those who already have recurring contracts, it usually pays off — and, with a balance sheet in hand, you gain access to larger tender notices, which require economic and financial qualification and where competition is much lower.

Start small, deliver well, keep your certificates and grow when volume calls for it. It is the same path that companies that are large today once followed — almost always starting with a direct award worth a few thousand reais.
