Chargebacks Explained: How They Work and How to Prevent Them

What a chargeback is

A chargeback is a reversal started by the cardholder's bank, not by you. The cardholder tells their bank they did not authorize a charge, did not receive what they paid for, or were charged wrongly. The bank takes the money back through the card network, and your provider debits it from your account, usually with a chargeback fee. You then have a limited window to respond.

Why customers dispute charges

The common reasons are fraud, where a stolen card was used; unrecognized charges, where the customer does not recognize your business name on their statement; goods or services not received or not as described; cancelled recurring billing that kept charging; and duplicate or incorrect amounts. A growing share are so-called friendly fraud, where a real customer disputes a real purchase, sometimes by mistake.

What a chargeback costs

You lose the sale amount unless you win, you pay a fee to your provider, and you lose the goods or time you already gave. If your chargeback count rises too high relative to your sales, the card networks can place you in monitoring programs with extra fees, and your provider can hold reserves or close the account. Keeping disputes low is a cost issue and an account-health issue.

How the response works

Your provider notifies you and tells you the reason code and deadline. You submit evidence that answers that specific reason: proof of authorization such as a chip read or signed receipt, proof of delivery, the customer's acceptance of your terms, communication with the customer, and your refund or cancellation policy. The issuing bank reviews it. Respond before the deadline; a missed deadline is a loss.

In-store prevention

Take cards by chip or tap rather than typing numbers, which gives you better liability protection. Keep itemized receipts, signed on large sales. Post your return and refund policy at the register and print it on receipts.

Online and phone prevention

Use address verification and card security code checks, 3-D Secure where it helps, and clear checkout terms that customers actively accept. Send order and shipping confirmations, use tracking, and require signature on delivery for high-value items. For phone orders, send a payment link rather than typing card numbers.

Recurring billing

Get written consent to store and charge a card, send reminders before renewals, make cancellation easy and stop charging immediately when a customer cancels. Most recurring disputes come from charges the customer thought they had stopped.

Your descriptor

The business name on the customer's card statement should be the name they know you by, with a phone number or website. Confusing descriptors cause unrecognized-charge disputes that never needed to happen.

The life of a chargeback

A dispute usually starts with a customer calling their bank or clicking a button in their banking app. The bank decides whether to raise a chargeback and assigns a reason code. The card network passes it to your provider, which debits the amount from your account and notifies you. You gather evidence and submit a response. The bank reviews it and either reverses the chargeback in your favour or lets it stand. Some disputes go through more than one round. Throughout, the deadlines are set by the card networks and communicated by your provider; missing one usually means losing by default.

Reason codes decide the evidence

Each chargeback carries a reason code that says what the customer claims. The evidence has to answer that claim. For a fraud claim on an in-person sale, a chip or tap record is strong. For goods not received, tracking with a delivery confirmation to the billing address helps. For a cancelled subscription, your cancellation policy and proof the customer did not cancel matter. Sending a generic bundle of receipts for every dispute wins less often than sending the specific proof the code asks for.

Alerts and early warnings

Some providers and card networks offer dispute alert services that tell you about a dispute before it becomes a chargeback, giving you a chance to refund and avoid the fee and the mark on your record. These services cost money, so they make most sense for businesses with recurring billing or online sales where disputes are frequent. Ask your provider what is available and what it costs.

Industries with higher dispute risk

Businesses that take payment long before delivering, such as travel, events, furniture and custom work, and businesses with recurring billing, see more disputes than a coffee shop. So do nightlife and businesses selling high-value goods online. If you are in one of these, invest in clear terms that customers accept at checkout, delivery or completion records, and prompt communication when something changes.

Tracking your ratio

Keep a monthly count of chargebacks and of sales, and watch the ratio. A rising ratio is a warning sign before any network program or provider review. Look for patterns: one product, one staff member, one sales channel. Most chargeback problems have a single operational cause that can be fixed.

Refunds done right

When you refund, refund to the same card used for the purchase, promptly, and tell the customer when to expect it. A customer who does not see a refund they were promised often disputes the original charge, and then you can lose twice.

Documentation to keep for every sale type

For in-store sales, keep the terminal record showing chip or tap, the itemized receipt and any signature. For online sales, keep the order confirmation, the IP address and device details your platform records, address verification and security code results, the terms the customer accepted, and shipping and delivery records. For services, keep the signed agreement, proof the service was delivered, and any messages with the customer. Store these where staff can find them quickly, because response deadlines are short.

What not to do

Do not argue with the customer's bank in emotional terms, submit irrelevant documents, or re-charge a customer's card after a chargeback without their consent. Do not ignore a chargeback because the amount is small; unanswered disputes still count against your ratio.

Where to start this week

Check your billing descriptor, print your refund policy on receipts, confirm chip and tap are working on every terminal, and set a calendar reminder to review disputes each month.

When to refund instead

If a customer contacts you first, a refund is usually cheaper than a chargeback: no chargeback fee and no mark against your ratio. Train staff to resolve complaints before they reach the bank.
