O que é um “ Chargeback ”? Definição de “ Chargeback ”

Uma chargeback é uma reversão forçada de uma transação com cartão, iniciada pelo banco do titular do cartão ou pelo emissor do cartão, e não pelo Lojista. Em termos simples: o banco do cliente retira o dinheiro da conta do Lojista e o devolve ao titular do cartão.

The right to do this is written into U.S. federal law. The Fair Credit Billing Act of 1974, implemented as Regulation Z section 1026.13, lets a cardholder dispute a billing error with their card issuer within 60 days of the statement, without involving the merchant first. That consumer-protection mechanism is what most people mean when they ask what a chargeback is.

The catch: most chargebacks today are not true fraud. In Mastercard's 2025 Global Chargebacks Outlook, merchants identify only 45% of their own chargebacks as outright fraud, meaning most disputes come from something else, most often a legitimate purchase disputed anyway ("friendly fraud"). The same report projects global chargeback volume will reach 324 million transactions by 2028, a 24% increase.

O que é um “ chargeback ”?

A chargeback is a rules-based dispute mechanism run by the card networks that lets an issuing bank take back a settled card payment from a merchant on the cardholder's behalf. It is not a refund: the merchant does not agree to it, pays a fee for it, and has to submit evidence to reverse it. Every chargeback involves five parties:

• Titular do cartão:O proprietário do cartão utilizado em uma transação.
• Lojista:A empresa que vendeu o produto ou serviço pelo site Disputa.
• Emissor:A instituição financeira ou empresa de cartão de crédito que emitiu o cartão ao titular.
• Adquirente:A instituição financeira responsável pela captação de pagamentos em nome do Lojista, geralmente por meio de um prestador de serviços de pagamento.
• Card network: Visa, Mastercard, American Express, or Discover, which sets the dispute rules and arbitrates when issuer and acquirer disagree. Visa publishes its merchant dispute categories and Mastercard its chargeback rules publicly.

Chargeback Meaning for Merchants: Fees, Ratios, and Reason Codes

For a merchant, the chargeback meaning goes beyond a lost sale. Each dispute pulls the transaction amount out of the account, adds a processor fee of $15 to $100 whether you win or lose, and counts against your chargeback ratio. Cross a network monitoring threshold and the ratio itself becomes a bigger problem than any single dispute: extra fees, remediation plans, and ultimately a terminated merchant account.

Every dispute also carries a reason code assigned by the issuer, and the code sets differ by card brand. See Chargeflow's full chargeback reason codes guide for the exact Visa, Mastercard, Amex, and Discover codes and what each means for evidence requirements.

What this looks like in practice depends on where a business sells. A Shopify store using Shopify Payments sees chargebacks directly in its Shopify admin dispute center, which packages the evidence for the acquirer automatically. On PayPal, what looks like "a chargeback" can actually be one of two different things: a card-network chargeback, following the same reason-code process described above, or a PayPal Claim filed under PayPal's own Buyer or Seller Protection policies, with no card network involved. The two run on different rules and different deadlines, so confirming which one is actually in play matters before responding.

What is a chargeback in banking?

In banking, a chargeback is the formal process an issuing bank uses to reverse a card transaction and reclaim the funds from the merchant's acquiring bank after a cardholder disputes it. The bank credits the cardholder, usually provisionally, then routes the case through the card network with a reason code. Under Regulation Z, which implements the Fair Credit Billing Act, a U.S. credit card issuer must acknowledge a written billing-error notice within 30 days and resolve it within two billing cycles, never more than 90 days. Debit card disputes follow Regulation E instead. To the bank, a chargeback is a liability decision between issuer and acquirer; to the merchant, it shows up as a debit plus a fee. Chargeflow's guide to how banks process disputes covers the issuer side in detail.

Types of Chargebacks

Every chargeback traces back to one of three root causes, and the cause determines both the evidence you need and the prevention that works:

1. True fraud (third-party fraud): Someone used stolen card credentials, and the real cardholder disputes a purchase they never made. In card-not-present sales the merchant carries the liability unless 3-D Secure shifted it to the issuer. Fraud screening before authorization and chargeback protection programs are the main defenses.
2. Friendly fraud (first-party misuse): The cardholder, or someone in their household, made the purchase but disputes it anyway, whether by mistake, out of confusion over a billing descriptor, or deliberately to keep the goods and the money. Visa puts friendly fraud at around 20% of all fraudulent disputes, and up to 30% for high-volume online merchants. Our guides to friendly fraud and deliberate chargeback fraud explain where the line sits and how to fight each.
3. Merchant error: Duplicate billing, wrong amounts, late shipments, unclear descriptors, or a refund that never posted. These are the most preventable disputes, and fixing them is the fastest way to reduce your chargeback rate.

Por que os titulares de cartões entram com ações judiciais Chargebacks

Card networks group those root causes into reason-code families. Below are the notable reasons why chargebacks happen:

• Fraude:As transações fraudulentassão o motivo mais comum. O titular do cartão alega que alguém realizou uma transação não autorizada com seu cartão de pagamento. Uma prevenção eficaz contra fraudes no comércio eletrônico reduz a frequência com que isso ocorre.
• Produto não recebido:O cliente alega que não recebeu os produtos ou serviços adquiridos.
• Crédito não processado: O comprador alega ter devolvido um produto ou cancelado uma transação, mas nenhum reembolso ou crédito foi emitido.
• Subscription Canceled: The customer claims you continued to charge recurring payments after they canceled a subscription.
• Erro administrativo: Ocomprador foi cobrado mais de uma vez pelo mesmo item, ou há um reembolso a ser efetuado. Trata-se de um erro de processamento ou humano, e não de uma fraud Lojista .
• Geral: Umpagamento sem categoria Disputa. Talvez seja necessário revisar as conversas anteriores com o cliente para entender por que ele contestou o pagamento.

Veja a seguir como esses motivos se relacionam com o que o titular do cartão alega e com que frequência eles ocultam a fraude amigável:

How Does a Chargeback Work? The Chargeback Process in 8 Steps

Então, como funciona o sistema de “ chargeback ” quando um cliente disputas contesta uma cobrança? A transação passa por uma sequência definida, regida pelas redes de cartões. Cada etapa tem um prazo, e o não cumprimento de um deles geralmente significa que o Lojista perde por falta de resposta.

1. The cardholder disputes the charge. They contact their issuing bank, typically within 120 days of the transaction (60 days from the statement for a billing error under the Fair Credit Billing Act).
2. The issuer reviews the claim. If it looks valid, the bank assigns a reason code and issues provisional credit to the cardholder.
3. The chargeback is filed through the network. The disputed amount plus a chargeback fee is debited from the merchant's account before the merchant has said a word.
4. The merchant is notified. The acquirer or processor passes on the case. The merchant must accept the loss or decide to fight, usually within 7 to 21 days at the processor level even though network rules allow 30 to 45.
5. The merchant gathers compelling evidence. Order records, delivery confirmation, IP and device data, customer communication, and proof the cardholder agreed to the terms.
6. Representment. The acquirer submits the evidence package to the issuer (Mastercard calls this a second presentment). See how chargeback representment works in practice.
7. The issuer decides. It either reverses the chargeback and returns the funds to the merchant or upholds it. Either side can escalate to pre-arbitration if it disagrees.
8. Arbitration (rare). The card network rules on the case, and the losing party pays a case ruling fee, separate from any pre-arbitration step: $600 at Visa (raised from $500 effective April 1, 2025) and $575 at Mastercard (raised from $400 effective March 2024), as of 2026. Most merchants only escalate high-value disputes.

Um exemplo de ` Chargeback `, passo a passo

Veja como isso funciona na prática: um cliente compra fones de ouvido no valor de US$ 120 em uma loja online e, três semanas depois, informa ao seu banco que o pacote nunca chegou. O banco emissor abre uma contestação ( chargeback), atribui o código de motivo “Produto não recebido” e devolve os US$ 120 ao titular do cartão imediatamente, antes mesmo que o comerciante ( Lojista ) seja notificado. O Lojista então constata que o Disputa , mais uma taxa de 25 dólares chargeback , já foi deduzido de sua conta, tendo 30 dias para responder. Se o Lojista tiver uma confirmação de entrega comprovando que o pacote foi assinado no endereço do cliente, ele envia essa evidência por meio de seu adquirente (representment). O emissor analisa a evidência e, se for convincente, reverte o chargeback: os 120 dólares voltam para o Lojista, embora a taxa chargeback normalmente não seja reembolsada em nenhum dos casos.

Chargeback Reembolso x Estorno: Qual é a diferença?

Lojistas Costuma-se usar “chargeback ” e “refund” de forma intercambiável, mas um terceiro termo, “reversal”, acaba sendo esquecido, embora seja a forma mais rápida e econômica de resolver o problema entre as três. Quando usado corretamente, um “reversal” cancela uma transação antes mesmo de ela ser liquidada, sem envolver o “ Disputa ” nem nenhuma investigação bancária; um “refund” é voluntário e iniciado pelo “ Lojista ” após a liquidação; um “ chargeback ” é imposto pelo banco do titular do cartão após a liquidação e conta para o índice de “ chargeback ” do “ Lojista ”. Saber qual dessas situações o cliente está realmente descrevendo determina se é necessário tomar alguma medida.

Chargeback Fees and Time Limits at a Glance

Each card network sets its own clock for the cardholder, the merchant, and any escalation. The figures below are the network rulebook maximums; your processor's deadline is usually shorter, so treat the notification date, not the network limit, as your real deadline. Chargeflow's guide to chargeback time limits breaks these down by reason code.

On top of network fees, your processor charges its own chargeback fee, typically $15 to $100 per dispute regardless of outcome. Stripe, for example, charges a non-refundable $15 dispute fee in the U.S. and notes that issuers usually take 60 to 75 days to rule once evidence is submitted. Chargeflow's breakdown of chargeback fees and costs shows how these add up per case.

É possível usar o ` Disputa ` com o ` Chargeback ` como ` Lojista`?

Yes. A chargeback is not a final loss until the response deadline passes. If the claim is wrong, you contest it through representment: submit compelling evidence to your acquirer within the network time limit and the issuer has to re-examine the case. Merchants who respond win a meaningful share: Datos Insights puts the merchant win rate on represented disputes at around 54%, and organized, automated evidence pushes it higher. (You may also see a separate ~43.8% industry-wide average cited elsewhere; that figure comes from a different field report and a different survey population, not a contradiction of this one.)

The work is in the details. Each reason code demands different evidence, each network formats it differently, and a late or incomplete package loses by default. That is why chargeback management has become its own discipline, and why most growing merchants automate it rather than assign it to support staff. Chargeflow handles evidence collection and submission for every dispute automatically, and charges only on recovered revenue.

Perguntas frequentes sobre Chargebacks

O que é um “ chargeback ” em termos simples?

A chargeback is when a cardholder's bank reverses a card payment and pulls the funds back from the merchant, usually after the customer disputes the charge. It is a consumer-protection tool created by the Fair Credit Billing Act and run under the card networks' rules.

Qual é a diferença entre um “ chargeback ” e um reembolso?

A refund is voluntary: the merchant returns the money directly to the customer and nothing else happens. A chargeback is forced by the customer's bank, comes with a $15 to $100 processor fee, and counts against the merchant's chargeback ratio regardless of whether the merchant agrees with the dispute.

Quanto tempo leva para fazer um exame de “ chargeback ”?

Most chargebacks resolve in 30 to 90 days, but the full process can run 120 to 150 days if the case goes to arbitration. Cardholders typically have 120 days to file, and merchants usually have 7 to 21 days at the processor level (30 to 45 under network rules) to respond.

Do merchants ever win chargeback disputes?

Yes. Merchants who submit compelling evidence before the deadline win roughly half of the chargebacks they contest: Datos Insights puts the merchant win rate at around 54% of represented disputes. Win rates rise sharply with organized evidence and automation; Chargeflow customers recover up to 4x more chargebacks than merchants responding manually.

Do merchants get penalized for chargebacks?

Yes, in three ways. Each chargeback costs the transaction amount plus a non-refundable processor fee. Every dispute also raises the merchant's chargeback ratio, and crossing a network threshold such as the Visa VAMP or Mastercard ECM limits triggers monthly fines and remediation plans. Persistent excess can end in a terminated merchant account and a listing that makes it hard to get a new one. A chargeback does not report to the cardholder's credit file.

What does chargeback mean in accounting or IT?

Outside payments, "chargeback" has two other meanings. In accounting and IT, a chargeback is an internal cost allocation: a shared-services or IT department bills business units for the resources they consume. In wholesale distribution, a chargeback is a deduction a retailer or distributor takes against a supplier's invoice. Neither involves a card network or a cardholder dispute; this article covers the payments meaning only.

Como é que Lojistas PREVENÇÃO chargebacks ?

Use clear billing descriptors, transparent refund policies, delivery confirmation, and responsive support so customers contact you before their bank. Pre-chargeback chargeback alerts from Ethoca and Verifi let you refund a disputed transaction before it becomes a formal chargeback, and pre-transaction fraud screening stops true fraud from being authorized in the first place.
