Most chargebacks merchants lose were winnable. The product shipped, the address matched, the customer signed for the package — and the dispute still came back as "lost" because the response was rushed, incomplete, or aimed at the wrong reason code. This guide walks through exactly what happens when a chargeback is filed on Shopify Payments, what evidence to gather, how to write a rebuttal that actually persuades, and when fighting a dispute is the wrong move.
What Happens When a Chargeback Is Filed
You're not the first person to find out about a chargeback. The customer is. They call their bank, claim they didn't authorize the purchase or didn't get the product, and the bank pulls the funds back from the card network on their behalf. From there it moves down the chain:
- The cardholder contacts their issuing bank — not you, and usually not Shopify either.
- The bank notifies the card network (Visa, Mastercard, Amex, or Discover) and assigns a reason code.
- The network notifies Shopify Payments, which debits the disputed amount plus a $15 chargeback fee from your account.
- You get a dispute notification in your Shopify admin under Orders → the affected order, and via email.
- You have a short window to submit evidence — typically 7 to 21 days depending on the network and the reason. Visa moves the fastest. Amex tends to be the strictest on formatting.
- If you don't respond at all, you automatically lose. The funds stay with the cardholder, the fee stays gone, and the dispute counts against your chargeback ratio.
The order of operations matters because it shapes how you should think about a dispute. The cardholder has already convinced one party — their own bank — that they have a case. Your evidence has to be strong enough to flip that decision.
The Evidence Deadline
The deadline is the single most important fact about your dispute, and the easiest thing to get wrong. Miss it by an hour and the strongest case in the world becomes a loss by default. Shopify Payments shows the deadline at the top of the dispute page in your admin: Orders → the disputed order → Manage dispute. It's labeled "Respond by" with a specific date.
Two rules on deadlines:
- Submit before the deadline, every time. Even if your evidence is incomplete. Partial evidence beats no evidence — a dispute submitted with tracking but no AVS data still has a real chance. A dispute that auto-loses has none.
- Don't wait until the last day. Shopify will not let you edit a submission once it's in. If you submit on day 6 and remember a key piece of evidence on day 7, you're stuck.
What Evidence to Collect by Dispute Type
The single biggest reason merchants lose disputes is submitting generic evidence. Each reason code has different requirements. The bank's reviewer is looking for specific things, and a delivery confirmation does nothing for a fraud claim while a fraud score does nothing for a "not received" claim. Match your evidence to the code.
Fraud (Visa 10.4, Mastercard 4837, Amex F29)
The cardholder claims they didn't authorize the purchase. You need to show that the person who placed the order was almost certainly the cardholder.
- AVS match — Address Verification System result showing the billing address matches what the card issuer has on file.
- CVV match — confirmation that the security code on the back of the card was entered correctly.
- IP address and geolocation from checkout, ideally near the billing or shipping address.
- Customer purchase history — prior successful orders from the same email, name, or device fingerprint.
- Order confirmation email sent to the customer's address (and not bounced or marked as spam).
- Delivery confirmation to the billing address — fraudsters almost never ship to the real cardholder's home.
Merchandise Not Received (Visa 13.1, Mastercard 4855)
The customer says the product never arrived. Your job is to prove it did.
- Tracking number tied to the carrier (USPS, UPS, FedEx, DHL).
- Delivery confirmation with the date and time of delivery.
- Signature confirmation if you have it — strongest for orders over $750, which usually require it under card network rules.
- Shipping address that matches the order — if you shipped to a different address than what the customer placed, that's a problem.
- Carrier scan or delivery photo — UPS and FedEx now include photos of the package at the door on most residential deliveries.
Not As Described (Visa 13.3, Mastercard 4853)
The customer received the product but claims it wasn't what was advertised. You need to show that what they got matches what was sold.
- Original product listing — the page as it existed on the order date, with photos and full description.
- Proof the shipped item matches the listing — SKU records, fulfillment notes, photos if available.
- Return policy clearly displayed on your store, with a screenshot of where it lives at checkout.
- Customer communication — any emails, support tickets, or chat logs. The strongest version is a customer who never contacted you about a problem before going straight to a chargeback. That undermines their claim.
How to Write an Effective Rebuttal
The rebuttal letter is what the bank's reviewer reads first. They're processing dozens of disputes a day. Make it easy for them to side with you.
- Address the specific reason code. If it's 13.1 (not received), every sentence should be about delivery. Don't drift into product quality or fraud signals — they're irrelevant and they dilute your case.
- Be factual and professional. No exclamation points, no editorializing about the customer, no hand-wringing about how unfair the chargeback is. Reviewers tune that out instantly.
- Reference each piece of evidence by name. "See attached USPS tracking confirmation showing delivery to 1234 Main St on March 12 at 2:47 PM." Tell the reviewer what to look at and why it matters.
- Explain why the evidence contradicts the claim. Don't just attach a tracking number — say: "The cardholder claims the item was not received. USPS records confirm delivery to the billing address, and the order was signed for by a household member."
- Keep it under 500 words. Reviewers skim. A focused page beats a meandering three.
- Never accuse the customer of lying. Even if it's obvious friendly fraud. State the facts; let the evidence accuse for you.
Common Mistakes That Lose Disputes
Most lost disputes don't lose on the merits. They lose on these:
- Missing the deadline. The number one cause of automatic losses.
- Submitting without key evidence. A "not received" response with no tracking number is functionally an admission. Don't submit a dispute response that omits the one piece of evidence the reason code requires.
- Writing an emotional or angry rebuttal. "This is clearly fraud and the customer is lying" reads as unprofessional and shifts focus away from your evidence.
- Submitting evidence that contradicts your case. If your fraud risk score for the order was high, don't include it. If the AVS partially matched, don't lead with AVS. Lead with your strongest evidence and don't volunteer weaknesses.
- Not including your return policy on a "not as described" dispute. The bank wants to see that the customer had a path to resolution that didn't involve a chargeback.
- Generic responses. A canned template that doesn't address the specific reason code signals to the reviewer that you didn't take the case seriously.
When to Accept vs Contest
Not every chargeback is worth fighting. Picking your battles protects your time and your win rate.
Accept when:
- You know the customer is right — the order genuinely went wrong.
- You have no meaningful evidence and the reason code requires it.
- The amount is small enough that an hour of your time is worth more than the recovery.
Contest when:
- You have tracking and delivery proof for a "not received" claim.
- The customer received the product and the order was fulfilled as described.
- AVS, CVV, and IP all line up on a fraud claim — that's textbook friendly fraud.
- The disputed amount is large enough that a 50/50 shot is worth the effort.
One accepted chargeback won't hurt you. Card networks care about your chargeback ratio — disputes as a percentage of transactions — not whether you accepted any individual case. Visa's threshold for excessive chargebacks is roughly 0.9%, with stricter monitoring above 0.65%. A single accepted dispute on a healthy account is invisible. A pattern of ignored deadlines is not.
