Chargebacks

Chargeback
Prevention & Representment
Stop them, then win them

A chargeback costs you the sale, the product, a fee, and a hit to the ratio that decides whether you keep processing at all. The good news: most are preventable, and many of the rest are winnable. Here's how to do both.

The short version
  • A chargeback is worse than a refund: you lose the goods, pay a fee, and it counts against your chargeback ratio.
  • The biggest single category isn't real fraud — it's "friendly fraud," where a real customer disputes a real purchase.
  • Prevention is a recognisable descriptor, fast support, clear policies, and fraud screening. It's cheaper than every other step.
  • Representment — fighting the chargeback with evidence — is worth it when the transaction was legitimate and you can prove it.

Refunds are annoying; chargebacks are dangerous. When a customer goes to their bank instead of to you, you don't just lose the money — you pay a non-refundable fee, you usually lose the product too, and the case is added to the ratio your processor and the card networks use to decide if you're a risk. Let that ratio climb and you end up where our processor account-attention guide picks up: reserves, fines, freezes.

The three kinds of chargeback

  • True fraud. A stolen card was used on your store. The real cardholder disputes it — legitimately. Your defence is preventing it at checkout, not fighting it after.
  • Merchant error. Wrong item, never shipped, double-charged, refund never processed, unclear billing. These are your fault and not worth fighting — fix the operation.
  • Friendly fraud. A real customer made a real purchase, then disputes it anyway — "I don't recognise this," buyer's remorse, "I forgot I ordered it," or gaming the system to get goods for free. This is the biggest and most winnable category.

Reason codes: read them, they tell you what to do

Every chargeback arrives with a reason code from the card network. You don't need to memorise hundreds of them — you need to recognise the buckets, because each bucket has a different winning move:

  • Fraud / "card not present." Won with proof the legitimate cardholder authorised and benefited from the purchase — AVS/CVV match, device and IP data, delivery to the verified address.
  • Product not received. Won with tracking and delivery confirmation, signed for on higher-value orders. The same evidence that wins PayPal "item not received" cases.
  • Product not as described / defective. Won with the accurate listing, photos, and any record the customer accepted the item or didn't use the returns process.
  • Subscription / "cancelled." Won with your terms, the cancellation policy the customer agreed to, and the usage log.

Prevention: the cheapest dollar you'll spend

You win the chargeback war before it starts. In order of impact:

  1. Make your billing descriptor unmistakable. A huge share of "I don't recognise this" disputes are customers who didn't connect a cryptic descriptor to your brand. Fix this first — it's free and it removes a whole category.
  2. Answer support fast. Customers charge back when they can't reach you. A reply in minutes, not days, redirects the frustration into a refund or a fix you control. This is the quiet reason fast support lowers disputes.
  3. Screen risky orders. Use AVS, CVV and fraud tools on high-value or mismatched orders. Stopping true fraud at checkout is the only way to "win" it.
  4. State policies clearly and get agreement. Returns, refunds, delivery windows and subscription terms, visible and accepted at checkout, become evidence later.
  5. Ship trackably and keep records. Tracking, delivery confirmation, and order communications, stored per order, are your representment kit.

Representment: how to actually win

Representment is submitting evidence to challenge a chargeback. Reviewers are fast and evidence-driven — a tidy, specific packet beats a long story every time. A winning packet usually includes:

  • A short, factual cover summary stating what the customer bought, when, and why the charge is valid.
  • Proof of delivery — tracking, timestamps, signature where relevant.
  • Verification data — AVS/CVV results, IP and device, login or account history.
  • The customer's own footprints — order confirmation, support messages, anything showing they received and engaged with the purchase.
  • Your published terms and the point at which the customer accepted them.
Don't fight everything. Fight the cases you can prove, concede the ones you can't, and fix the operations behind the merchant-error ones.

Fighting blindly wastes time and annoys your processor. Discipline — knowing which cases are winnable and submitting clean evidence quickly — is what turns representment from busywork into recovered revenue.

It's one funnel, not three

Card chargebacks, PayPal claims and Klarna disputes are the same problem wearing three uniforms. The same customer anxiety drives all of them, the same fast, evidence-ready operation defends all of them, and the same ratios decide whether you keep your payment accounts healthy. Run one desk across all three, and your numbers stay where processors like to see them.
