A large share of Brazilian public tenders (licitações) don't end in a contract — they end in a price registration record (ata de registro de preços). You compete, win, sign the record... and may sell nothing. Or sell far more than you expected, in orders that arrive without warning over an entire year.

Understanding this mechanism is essential, because it changes how you calculate prices, plan inventory and judge whether an opportunity is worth the effort. Many new suppliers celebrate the win, project revenue based on the record's total value and are disappointed when actual demand turns out to be a fraction of it. Others accept a tight price and find out, in the eighth month, that their costs have gone up and the record is still in force.

What the price registration system is

The Price Registration System (SRP) is a procedure in which the government runs a tender to set prices, not to buy immediately. At the end, a record is signed stating the unit price of each item, the winning supplier and the maximum estimated quantity. While it is valid — as a rule up to twelve months, with extension allowed under the terms of the law — the agency issues supply orders according to its actual needs.

The logic is good for the government and makes sense for the market. Instead of running a tender for school meals every time stock runs low, the city government (prefeitura) runs one tender and buys throughout the year. Instead of estimating with impossible precision how many tires the fleet will use, it registers the price and buys them as they wear out.

For the supplier, the trade-off is living with uncertain demand. And it is precisely this uncertainty that has to go into your calculations before you bid.

A price record is not a contract: the distinction that changes everything

The record registers the price and creates an expectation of a contract. The contract — or the commitment note (nota de empenho), in simpler cases — comes later, with each concrete demand. There are three practical consequences:

The agency is not required to buy. It may purchase the full quantity, part of it or nothing at all. If the expected demand doesn't materialize, or if the budget gets tight, the record simply goes unused. There is no compensation for this, and nothing irregular about it: it is the nature of the instrument.

You are required to supply under the registered conditions, while the record is valid and within the registered quantity. Refusing without justification leads to sanctions. That's why registering a price you can't sustain for twelve months means taking on real risk.

The price is frozen, except for a duly proven economic-financial rebalancing. When input costs rise, this is where your margin evaporates.

How to price for twelve months

Pricing follows the same structure as any bid — direct cost, logistics, taxes, financing cost, overhead and margin, as detailed in how to price your bids to sell to the government — with three adjustments specific to the SRP.

Adjustment 1: your supplier's time horizon. Ask for quotes with long validity, or negotiate with your supplier the possibility of holding prices for an extended period. When that isn't possible, build in a reserve for price changes. Working with today's quote over a one-year term is the classic recipe for losses in the second half of the year.

Adjustment 2: the cost of availability. Staying ready to deliver within five days has a cost, even when the order doesn't come. It may mean idle inventory, a contract with a carrier or reserved production capacity. This cost is real and has to show up in the price.

Adjustment 3: split deliveries. Price records tend to generate small, frequent deliveries. Calculate the logistics cost per delivery, not for the total. Twenty deliveries of R$ 2,000 cost much more than one delivery of R$ 40,000.

Economic-financial rebalancing: what it is and how to request it

When an unforeseeable event, beyond the parties' control, substantially changes the economic balance of the agreement, the law guarantees rebalancing. It is the instrument that allows the registered price to be revised without having to abandon the record.

It is not meant to fix your own calculation errors, nor to track normal market fluctuations that were foreseeable at the time of the bid. It is meant for the extraordinary: a sudden spike in a commodity, a tax change, an event that structurally alters costs.

The request is administrative and requires documentary evidence: purchase invoices from before and after, the manufacturer's published price increases, industry indices. The more objective the demonstration, the better the odds. While the review is under way, the obligation to supply remains — another reason not to count on rebalancing when setting your price.

Piggybacking: when another agency uses your price record

Joining the record by an agency that did not take part in the tender — known as piggybacking (carona) — allows another entity to buy under the same registered conditions, within legal quantity limits.

For the supplier, it is both an opportunity and a risk. An opportunity because it increases volume without a new tender: one municipality's record can be used by another, and revenue grows with no prospecting cost. A risk because the additional demand may exceed the capacity you planned for — and joining depends on your consent, which is the point many people overlook.

Rule of thumb: evaluate each piggybacking request with the same discipline as a new bid. Check your delivery capacity, the logistics for the new region and whether the registered price still covers your cost. Accepting a request on reflex, in a distant region and at a price set months ago, is a decision that tends to cost dearly.

Reserve list: the runner-up matters too

At the end of the tender, besides the winner, other bidders who agree to supply at the first-place price may be registered — the reserve list (cadastro de reserva). They are called upon if the main supplier cannot deliver or has its record canceled.

Is it worth joining? It depends. If the registered price covers your cost with an acceptable margin, yes: it's a chance of revenue with no extra effort, and there is no obligation until you are called. If the winner's price is below your floor, it makes no sense — you would be committing to an unworkable price.

Estimated quantity is not a guarantee

The tender notice (edital) lists the maximum quantity per item. It is an estimate based on historical consumption, and reality tends to land between 40% and 80% of it, varying widely depending on the item and the budget health of the government entity.

A common mistake: sizing inventory, hiring staff or negotiating volume with suppliers while counting on 100% of the record. Do the opposite: plan capacity for the high scenario, but plan cash flow for the low one. And, if your business needs predictability, keep in mind that the SRP is not the instrument that provides it — contracts with a fixed schedule are.

Advantages that make up for the uncertainty

Despite all this, price records are an excellent deal for many suppliers, for three reasons.

One tender, a year of supply. The cost of taking part — reading the tender notice, doing the math, attending the session — is spread over twelve months of orders.

A relationship with the purchasing department. A price record supplier becomes a frequent contact of the warehouse and the government department, which brings insight into upcoming tenders and the agency's real needs.

Scale through piggybacking. A well-executed record can be used by other government entities, multiplying volume without a new tender.

Managing, participating and non-participating agencies

Three roles appear in every price record, and they are worth telling apart, because they define who you deal with in each situation.

The managing agency (órgão gerenciador) runs the tender, signs the record and administers it: it tracks the remaining balance, authorizes piggybacking and processes rebalancing requests. It is your main point of contact for anything concerning the record itself.

Participating agencies expressed interest before the tender and had their demand included in the total quantity. They issue supply orders directly, within their share. In a price record of an inter-municipal health consortium, for example, each participating municipality buys its own share.

Non-participating agencies are the piggybackers: they weren't part of the tender and join later, with the managing agency's authorization and your consent. This is where the asymmetry that demands attention lies — the piggybacker may be hundreds of kilometers away, with logistics you didn't factor in when setting your price.

In practice, this means the same record can generate orders from very different sources. Keep your own record of the balance by source: how much has already been delivered to the managing agency, how much to each participant and how much to piggybackers. Relying on the agency's tracking is like relying on someone else's memory of your revenue.

What to do in the first thirty days of a price record

Once the record is signed, three steps prevent most of the year's problems.

Confirm the channels. Find out who issues the supply orders, how they arrive (email, system, official letter) and who the inspector responsible for receiving the goods is. An order that lands in an inbox nobody reads becomes a delay, and a delay becomes a fine.

Align receiving logistics. Ask for the exact address, receiving hours, whether appointments are required and which documents must accompany the delivery. Each agency has its own routine, and discovering it on the first delivery costs you a wasted trip.

Set up internal tracking. A spreadsheet with item, registered price, maximum quantity, remaining balance and current purchase cost. Review it monthly: it's what will tell you when costs have risen enough to justify a rebalancing request — and when the balance is about to run out.

Most common mistakes

• Projecting revenue from the record's total value and being disappointed by actual demand;
• Getting quotes from suppliers without extended validity and absorbing price increases alone;
• Forgetting the cost of split deliveries;
• Accepting piggybacking requests without reassessing cost and logistics;
• Joining the reserve list at a price below your own floor;
• Not tracking the record's balance and being caught off guard by a large order at the end of its term.

Frequently asked questions

Can I withdraw from the price record?

Requesting cancellation is possible in specific situations — such as a proven inability to perform due to a supervening event — but withdrawing without cause leads to sanctions. Treat signing as a firm commitment.

Can the record be extended?

Its term follows the limits of Law 14,133/2021 (Brazil's Public Procurement Law), with extension allowed in the cases and within the periods set by law. Check the specific clause in the tender notice, because it changes the time horizon of your price.

What happens if I can't deliver an order?

The agency may call on the reserve list and impose sanctions on you, depending on the severity. Communicating in advance and providing documented justification reduces the damage — see sanctions in public tenders.

Is it worth bidding for a price record even when demand is uncertain?

In most cases, yes — as long as the registered price is sustainable and your cost structure doesn't depend on the maximum volume. Treat the quantity as a ceiling, not a target.

How do I know if a tender is a price registration?

The notice itself says so, and Busca Licitações tender pages show the SRP badge when that is the case. You can also filter directly by price registration in the advanced search.

When the price record is canceled

A registration can be canceled before its term ends, and knowing the grounds helps you avoid surprises. On the supplier's side: failure to meet the conditions, unjustified refusal to fulfill orders, or a proven inability to maintain the price when rebalancing doesn't apply. On the government's side: a duly justified public-interest reason, or a registered price that has become higher than market prices.

That last ground surprises those who don't know about it. If the market drops and the record's price ends up above the going rate, the agency will call you in to negotiate a reduction. If you accept, the record continues at the new price; if you refuse, the registration may be canceled and the reserve list called upon. It is the mirror image of rebalancing — and it shows that a price record follows the market in both directions.

How to spot good price records

Favor items with recurring, predictable consumption — cleaning supplies, office supplies, foodstuffs, spare parts — at agencies with a consistent purchasing history. Each agency page shows how many contracts the agency has published and how often, which helps you estimate the real demand behind the estimated quantity.

Start with the open price registration tenders in your category and check, on each page, the quantity per item and the estimated unit price. With your price calculated for the right time horizon, the price record stops being a gamble and becomes what it really is: a year of open doors with a customer that is always buying.
