What Is a Chargeback?

What Is a Chargeback?

A chargeback is a reversal of a card payment, initiated by the cardholder's bank. When a customer disputes a transaction -- claiming it was unauthorised, the goods were not delivered, or the product was not as described -- they contact their card issuer, which can forcibly reverse the payment and return the funds to the customer's account.

Chargebacks were originally designed as a consumer protection mechanism, giving cardholders a safety net against fraud and unscrupulous merchants. However, the chargeback system has become a significant financial and operational burden for businesses, particularly as friendly fraud -- where customers abuse the system to reverse legitimate purchases -- has grown.

How the Chargeback Process Works

The chargeback process involves several parties and typically follows this sequence:

• Step 1 -- Customer disputes The cardholder contacts their bank (the card issuer) to dispute a transaction, providing a reason code
• Step 2 -- Issuer reviews The issuer evaluates the claim and, if it has merit, initiates a chargeback
• Step 3 -- Acquirer notified The chargeback is sent through the card network to the merchant's acquiring bank
• Step 4 -- Funds debited The transaction amount is debited from the merchant's account, along with a chargeback fee (typically 15 to 25 GBP)
• Step 5 -- Merchant notified The merchant receives notification and has the option to accept the chargeback or fight it through representment

The entire process can take anywhere from a few weeks to several months to resolve.

Common Chargeback Reason Codes

Each card network uses its own system of reason codes, but the most common categories include:

• Fraud / Unauthorised transaction The cardholder claims they did not authorise the payment
• Goods or services not received The customer says they never got what they paid for
• Product not as described What was delivered did not match what was advertised
• Processing errors Duplicate charges, incorrect amounts, or technical issues
• Cancelled recurring payment The customer cancelled a subscription but was still charged

The True Cost of Chargebacks

Chargebacks are expensive -- far more so than most merchants realise. The costs include:

• The transaction amount The full payment is reversed, but you have already delivered the goods or service
• Chargeback fees Your acquirer charges a fee for each chargeback, typically 15 to 25 GBP
• Administrative costs Staff time spent gathering evidence, responding to disputes, and managing the process
• Higher processing rates Merchants with high chargeback ratios face increased processing fees
• Monitoring programmes If your chargeback ratio exceeds card brand thresholds (typically 1% of transactions), you may be placed in a monitoring programme with additional fines and requirements
• Account termination Persistent high chargeback ratios can lead to your acquiring bank closing your merchant account

Preventing Chargebacks

Effective chargeback prevention requires a multi-layered approach:

Clear Communication

Many chargebacks result from misunderstandings. Ensure your business name on card statements is recognisable, provide clear product descriptions, communicate delivery timescales, and make your refund policy easy to find and understand.

Fraud Prevention

Use AVS (Address Verification Service), CVV verification, and 3D Secure for online transactions to reduce unauthorised use of stolen card details.

Good Customer Service

Make it easy for customers to contact you and resolve issues directly. Many chargebacks happen because the customer could not reach the merchant or gave up trying. A straightforward refund process is far cheaper than a chargeback.

Transaction Records

Keep detailed records of every transaction -- order confirmations, delivery tracking, customer communications, signed agreements, and call recordings (where compliant). This evidence is essential if you need to fight a chargeback through representment.

Chargebacks and Telephone Payments

Telephone payments -- classified as MOTO transactions -- carry a higher chargeback risk than in-person transactions because the card is not physically present. Without 3D Secure authentication (which is not available for MOTO transactions), there is no liability shift to the card issuer.

This means merchants bear full liability for fraudulent chargebacks on phone payments. To mitigate this risk:

• Always collect and verify the CVV for every telephone transaction
• Use AVS to check the billing address
• Keep recordings or logs of the customer interaction (ensuring PCI DSS compliance)
• Train agents to recognise suspicious behaviour -- unusual order sizes, multiple failed attempts, or reluctance to provide verification details

Secure telephone payment platforms that capture card data via the customer's keypad (rather than the agent) also provide a clear audit trail showing that the cardholder entered their own details, which can be valuable evidence in chargeback disputes.

Chargebacks vs Refunds

A refund and a chargeback both return money to the customer, but they are very different processes. A refund is initiated by the merchant voluntarily -- the customer contacts the business, the business agrees to reverse the payment, and the funds are returned. A chargeback is initiated by the customer's bank without the merchant's agreement. Chargebacks carry additional fees, take longer to resolve, count against the merchant's chargeback ratio, and can have serious consequences for the merchant's ability to process payments. Wherever possible, resolving disputes through direct refunds is preferable to allowing them to escalate to chargebacks.
