When a customer takes money back: what merchants need to know about chargebacks

The payment that comes back

Picture this: three weeks ago you shipped an order. The money landed in your account, everything looked fine. Then one Tuesday morning you open your dashboard and find a negative transaction — the bank has returned the money to the customer. No warning. No conversation. The product is long gone.

That is a chargeback — and unlike a regular refund, you had no say in it.

Refund vs chargeback: not the same thing

A refund is voluntary. You decide to return the money — maybe the customer asked, maybe you made a mistake, maybe it is just good policy. The transaction reverses, and that is the end of it.

A chargeback is forced. The customer skips you entirely and goes straight to their bank, which opens a formal dispute and reverses the payment unilaterally. Think of it this way: a refund is when the customer comes back to your shop and you both agree to sort it out. A chargeback is when the customer calls head office and head office calls your landlord. You are not part of the conversation until the decision is almost made.

And there is a practical difference that stings: with a refund, you lose the sale amount. With a chargeback, you lose the sale amount plus a dispute fee — typically €15–25 per case — whether you win or lose.

Why customers file chargebacks

Three main reasons, and they matter because each requires a different response.

True fraud — someone used a stolen card. The real cardholder had nothing to do with your transaction. This is the cleanest case: no amount of evidence will change the outcome, and your job is purely prevention.

Friendly fraud — the customer made a legitimate purchase and then disputed it anyway. The most common pretexts: "I never received it," "I don't recognise this charge," "it wasn't as described." Studies consistently show that 60–80% of chargebacks in e-commerce fall into this category. The purchase was real; the dispute is not.

Processing errors — double charges, wrong amounts, a subscription that kept running after cancellation. These are the easiest to prevent because they come entirely from your side.

The numbers that define your risk

Card networks — Visa and Mastercard — monitor every merchant's chargeback ratio: the number of disputed transactions as a percentage of total transactions in a month.

Cross 1%, and you enter a formal monitoring programme. Expect higher fees, mandatory fraud audits, and a dedicated case manager watching your account.

Cross 2%, and the networks notify your acquiring bank, which can suspend or terminate your merchant account. At that point, getting a new account is significantly harder — you are now on the MATCH list (Mastercard's terminated merchant database), and most processors run that list before approving applications.

For most businesses, one or two chargebacks a month is normal. Ten is a signal. Fifty is a crisis.

Fighting a chargeback: representment

When you receive a chargeback notice, you have a window — typically 20 to 30 days — to submit a representment: evidence that the transaction was legitimate and the goods or services were delivered as promised.

What wins cases:

• Proof of delivery — signed receipt, courier tracking with delivery confirmation, IP address log showing the digital product was downloaded
• Communication history — emails, chat logs, support tickets showing the customer engaged with the product
• Transaction details — device fingerprint, billing address match, 3D Secure authentication confirmation
• Your policy — a refund and cancellation policy the customer agreed to at checkout (a checkbox or timestamp in your records goes a long way)

Win rates for merchants who respond with solid documentation run around 40%. That sounds low — but remember, most merchants never respond at all. For friendly fraud specifically, a well-documented response wins far more often.

One thing to know: if the dispute is coded as true fraud and 3D Secure was used, the liability shifts to the card issuer. You win automatically, without filing anything. This alone makes 3D Secure worth enabling.

Prevention beats recovery

No process for fighting chargebacks is better than not getting them in the first place.

Make your billing descriptor obvious. The name that appears on a customer's card statement should match what they know you as. "PLK FINANCE SRB" loses to "Polako Finance" every time — half of friendly fraud starts with a customer who genuinely doesn't recognise the charge.

Respond to complaints before customers escalate. Most people file a chargeback only after they tried to contact you and got nothing. A functioning support channel — even just a working email — catches the majority of disputes before they become formal.

Screen transactions at the front door. Country mismatch between billing address and IP, cards that trigger multiple failed attempts in a row, orders placed with free email domains at unusual hours — none of these is a guarantee of fraud, but they are signals. A basic fraud scoring layer reduces exposure significantly.

Enable 3D Secure. In Serbia, strong customer authentication (SCA) requirements apply to card payments. Beyond compliance, 3DS shifts fraud liability off your plate. It adds one step for the customer; it removes the largest financial exposure for you.

One advantage QR payments have always had

This is worth saying plainly: IPS QR transfers cannot be charged back. The customer sends money directly from their account to yours. There is no card network, no issuing bank, no dispute mechanism. The payment is final the moment it clears.

This is why the two payment types are not directly comparable on risk. A business accepting only QR payments has zero chargeback exposure. A business accepting cards accepts chargebacks as a cost of doing business — and should plan for them accordingly.

In short

• A chargeback is a bank-forced reversal, not a refund — you pay a dispute fee regardless of outcome
• 60–80% of chargebacks are friendly fraud: legitimate purchases disputed by the buyer
• Above 1% chargeback ratio: monitoring. Above 2%: account termination risk
• Fight disputes with delivery proof, communication logs, and 3D Secure authentication records
• Prevention: clear billing descriptor, responsive support, fraud screening, 3D Secure enabled
• QR/IPS transfers have no chargeback mechanism — financial finality is their structural advantage
