What Is a Chargeback?

Chargebacks Explained

A chargeback is essentially a forced refund. Instead of asking the merchant for their money back, the customer goes directly to their bank (the card issuer) and disputes the transaction. The bank then reverses the payment, pulling the funds from the merchant's account and returning them to the customer.

Chargebacks were introduced as a consumer protection mechanism, giving cardholders a way to recover money from fraudulent or unauthorised transactions. However, they are now used for a wide range of disputes, including goods not received, services not as described and billing errors.

How the Chargeback Process Works

• The customer contacts their bank — they report a problem with a transaction and request a chargeback.
• The issuing bank reviews the claim — if the dispute appears valid, they initiate the chargeback and provisionally credit the customer's account.
• The merchant is notified — the acquiring bank (the merchant's bank) informs the merchant of the chargeback and debits the disputed amount, plus a chargeback fee.
• The merchant can respond — this is called representment. The merchant can submit evidence (receipts, delivery confirmation, communication records) to challenge the chargeback.
• A decision is made — the card scheme or issuing bank reviews the evidence and either upholds the chargeback or reverses it in the merchant's favour.

Common Reasons for Chargebacks

• Fraud — the cardholder did not authorise the transaction (their card was stolen or compromised).
• Goods not received — the customer paid but never received what they ordered.
• Not as described — the product or service was significantly different from what was advertised.
• Duplicate charge — the customer was charged twice for the same transaction.
• Friendly fraud — the customer made a legitimate purchase but disputes it anyway, sometimes forgetting the transaction or deliberately trying to get a free product.

The Cost of Chargebacks

Chargebacks are expensive. Beyond losing the sale amount, merchants typically pay a chargeback fee (often between 15 GBP and 25 GBP per dispute). There are also hidden costs: the time spent gathering evidence, the administrative burden of responding, and the potential damage to your merchant account standing. If your chargeback ratio gets too high — typically above 1% of transactions — your payment processor may increase your fees, impose restrictions or even terminate your account.

Preventing Chargebacks

• Use clear billing descriptors — make sure your business name appears clearly on card statements so customers recognise the charge.
• Provide excellent customer service — make it easy for customers to contact you directly to resolve issues before they go to their bank.
• Keep records — store receipts, signed agreements, delivery confirmations and communication logs.
• Use 3D Secure — authenticated transactions benefit from a liability shift, protecting you from fraud-related chargebacks.
• Implement fraud screening — use tools to detect suspicious transactions before they are processed.
