What is a chargeback, and how can merchants prevent them?
A chargeback is a forced transaction reversal initiated by a cardholder's bank, not by the merchant. When a cardholder disputes a payment with their issuing bank and the claim is upheld, the bank pulls the funds back from the merchant automatically, usually along with a dispute fee. Unlike a refund, which the merchant controls, a chargeback takes the decision out of the merchant's hands entirely.
Think of it like a bank acting as a referee who can overturn a sale after the final whistle has already blown. The merchant does not get a say until the dispute is already underway, and by then, the goods or service have often already been delivered.
Chargeback requests fall into two camps. The first is friendly fraud, where a cardholder genuinely does not recognise a transaction or is unsure how to request a refund the normal way. Merchants report that 42% of all chargebacks fall into this category. The second is chargeback fraud, where a customer knowingly disputes a transaction despite having received the product or service as promised.
What is the difference between a chargeback and a refund?
The core difference is who controls the process. A refund is a direct agreement between a merchant and a customer: the customer asks, the merchant approves, and the money moves back without a bank getting involved. A chargeback skips that conversation entirely. The cardholder goes straight to their issuing bank, the bank investigates, and if the claim holds up, the bank reverses the transaction and bills the merchant for it, fee included.
| Refund | Chargeback | |
| Who initiates it | Customer, directly with the merchant | Customer, via their issuing bank |
| Merchant control | Full control over approval | No control once filed |
| Speed | Can be processed in minutes | Can take weeks to resolve |
| Cost to merchant | Returned sale amount only | Returned amount plus dispute fee |
| Impact on dispute ratio | None | Counts toward chargeback ratio |
Why do chargebacks happen?
Three triggers account for most chargebacks merchants face.
Fraud. A cardholder files a dispute when their card is used without authorisation, often after a stolen card or a phishing attack. This is the scenario where strong fraud prevention tools matter most, since catching the fraudulent transaction before it settles is far cheaper than fighting the chargeback afterwards.
Undelivered or unsatisfactory goods. These disputes arise when a customer does not receive their order or is unhappy with how a shipping issue was handled. Some customers also claim non-delivery purely to secure a free refund, which is why tracking numbers on every order matter as much for evidence as for logistics.
Technical errors. Duplicate charges, failed payment retries that still post, or a billing descriptor the customer does not recognise all push people toward their bank instead of their inbox. A clear, recognisable statement descriptor, one that includes your business name, resolves a surprising share of these before they ever become a dispute.
How does the chargeback process work?
When a chargeback is triggered by a processing error, the issuing bank starts the process and the acquiring bank manages the case on the merchant's behalf. When a cardholder initiates the dispute directly, it lands with the merchant first, who then chooses to accept it or challenge it with supporting evidence.
If you choose to fight it, you submit documentation, proof of delivery, authorisation records, customer communications, to your acquiring bank, which forwards it to the issuing bank. The issuing bank has the final say. Disputing a chargeback costs time and money regardless of the outcome, and a high dispute rate can strain your relationship with your acquirer or even put your merchant account at risk.
This is exactly the gap that modern dispute tools are built to close. Visa's Rapid Dispute Resolution (RDR) and Mastercard's pre-dispute alerts now let merchants resolve eligible cases before they ever become a formal chargeback, cutting both the cost and the back-and-forth out of the process. You can see how this works inside payabl.'s chargeback management and dispute solutions, which brings Visa RDR, Mastercard alerts, and real-time dispute tracking into one dashboard on payabl.one.
How can merchants prevent chargebacks?
Every business, regardless of size, needs a chargeback prevention strategy paired with strong fraud tools at the gateway level. The following steps reduce exposure before a dispute ever reaches your desk.
- Follow verification protocol. Capture IP addresses, digital signatures, and CVV checks, and use authentication services such as Verified by Visa or Mastercard Identity Check so fraud liability shifts to the issuing bank rather than your business.
- Use a recognisable payment descriptor. Make sure your statement descriptor clearly shows your business or website name so customers recognise the charge instantly.
- Respond fast. 42% of customers expect a response within one hour. Quick, clear replies to disputes resolve many cases before they escalate to a formal chargeback.
- Stay vigilant on fraud. AI-powered fraud monitoring and real-time transaction scoring catch suspicious activity before it settles, rather than after a customer has already disputed it.
- Publish a clear returns and refunds policy. Make it easy for customers to request a refund directly from you, so they never need to involve their bank.
- Train your team. Technology catches most fraud patterns, but staff who know what to flag close the gaps automation misses.
- Keep solid records. Transaction logs, authorisation details, and delivery confirmations are your strongest evidence if a dispute is ever challenged.
- Send subscription reminders. Customers who forget a recurring charge often dispute it rather than cancel it, so a reminder before billing reduces unnecessary chargebacks.
Why do chargebacks spike around Black Friday?
Peak sales periods multiply every chargeback risk at once. More transactions mean more fraud attempts, more shipping delays, and more impulse purchases that customers later regret and try to reverse through their bank instead of a return. payabl.'s own research found that 86% of merchants have been targeted by scams or fraud attempts in the past 12 months, and that Black Friday and Cyber Monday are flagged by over a third of retail leaders as the riskiest period of the year for fraud. Separate research shows that fraud pressure has become severe enough that 48% of UK retail leaders have considered closing or scaling back their operations in 2026.
Think of Black Friday as a bridge during rush hour: it can carry enormous traffic safely, but only if it was engineered for that load in advance. A chargeback strategy you have not stress-tested before your biggest sales weekend is a bridge you are hoping holds.

A strong chargeback strategy protects revenue, reputation, and growth all at once
Chargebacks are not going away as ecommerce keeps growing, but they are manageable.

Frequently asked questions
What is a chargeback in simple terms?
A chargeback is when a cardholder's bank forcibly reverses a payment and returns the funds to the customer, usually after the customer disputes the transaction with their bank rather than the merchant.
What is the difference between a chargeback and a refund?
A refund is agreed directly between the merchant and the customer. A chargeback is enforced by the card issuer after the customer disputes the charge with their bank, and the merchant has no control over whether it is initiated.
Why do chargebacks happen?
Chargebacks typically happen for one of three reasons: unauthorised or fraudulent use of a card, undelivered or unsatisfactory goods, or technical errors such as duplicate charges.
How long does a merchant have to respond to a chargeback?
Response windows vary by card scheme and acquirer, but merchants are generally given a limited number of days, often between 7 and 30, to submit evidence disputing the chargeback.
Can a merchant prevent all chargebacks?
No business can eliminate chargebacks entirely, but strong fraud monitoring, clear refund policies, recognisable billing descriptors, and fast customer service significantly reduce how often they occur.
Do chargebacks increase during Black Friday?
Yes. Peak sales periods like Black Friday and Cyber Monday see a sharp rise in both fraud attempts and chargebacks, driven by higher transaction volumes, shipping delays, and impulse purchases customers later regret.
