C08: Goods/Services Not Received

For merchants, a C08 chargeback can seem like a gut punch, and that’s also the case when you’re confident the order was fulfilled correctly. But understanding how this reason code works - what triggers it, what American Express expects in a response, and how to build a case - makes the difference between winning a dispute and losing revenue you rightfully earned.

This guide breaks down everything merchants need to know about C08 chargebacks: the conditions that cause them, the evidence that can support a rebuttal, common mistakes to avoid, and helpful steps to cut back on how they happen.

What Triggers a C08 Chargeback in the First Place

A C08 chargeback gets filed when a cardholder pays for something and never receives it. That sounds simple, but American Express defines “not received” more broadly than most merchants expect- it covers physical packages that never arrived, services that were booked but never performed, and online goods that failed to deliver.

The legal foundation here is the Fair Credit Billing Act of 1974, which gives cardholders the right to dispute a charge when goods or services weren’t delivered as agreed. Amex built its C08 reason code around this protection, which means the cardholder has a federally supported right to initiate the dispute.

These disputes usually stem from one of three things: a merchant error, a shipping or fulfillment failure, or a breakdown in communication between the two parties. A package gets lost in transit, a service provider cancels without notifying the customer, or a download link fails and the buyer assumes the worst.

The cardholder doesn’t need to prove negligence on the merchant’s part. They only need to show that what they paid for didn’t arrive. That distinction matters because some C08 disputes come from situations where the merchant did everything right but the delivery still failed.

Here is a quick look at the most common scenarios that cause a C08 claim.

Miscommunication is a bigger factor than most merchants know. A customer who can’t get a delivery update or a response from support is far more likely to go straight to their card issuer. The dispute starts not because the merchant failed to deliver, but because the customer had no way to find out what was happening. In some cases, a partial refund offered before the dispute resolves can complicate things further if the cardholder still feels the situation wasn’t fully addressed.

The C08 Chargeback Timeline Every Merchant Should Know

Time is the thing that determines if a merchant wins or loses a C08 dispute. Cardholders and their issuing banks have as high as 120 days from the transaction date to file a dispute, so a chargeback can land on your desk months after the original sale. That gap is long enough for a merchant to have already forgotten the order entirely.

Once the dispute is filed and you receive notification, the clock moves fast. You have just 20 days to submit a response to your acquirer. That is not a lot of time to pull together records, write a rebuttal, and package your evidence - especially if the original transaction was weeks or months ago.

After you submit your response, the process moves into American Express’s hands. They take roughly 20 to 30 days to review the evidence and reach a decision, which puts the total active resolution window at around 40 to 60 days from your response date. Here is what the full cycle looks like:

The 120-day filing window is worth thinking about from a record-keeping angle. If a dispute can arrive four months after a transaction, your documentation needs to be accessible for at least that long - and realistically longer. Waiting until a chargeback arrives to start looking for records puts you in a tough position.

The 20-day response window is where merchants lose the most ground. It seems manageable in isolation, but if your team is not already set up to respond to disputes quickly, that deadline can pass before a response is ready. Missing it means Amex will almost certainly side with the cardholder by default.

A picture of where you stand at each stage helps you treat a C08 dispute as a process to manage instead of a problem to respond to. The timeline is fixed, but your preparation is not.

Building a Defense Against a C08 Claim

Merchants win roughly 45% of chargebacks across all dispute codes, which means the strength of your response changes the outcome. A disorganized rebuttal with thin documentation is usually a losing one.

The most important thing you can do is pull together evidence that directly addresses the claim. For physical goods, that means delivery confirmations, carrier tracking data, and signed receipts where available. For online products or services, you need proof of delivery in a different form - access logs, download records, IP addresses linked to the account, or email confirmations showing the customer received what they paid for.

Communication logs matter more than most merchants expect. If the customer contacted you about non-receipt and you responded, that exchange is part of your evidence - it shows you were involved and tried to resolve the problem, which plays well in a dispute. If they never contacted you at all before filing a chargeback, that’s worth showing too.

The 120-Day Counter Angle

There’s a lesser-known defense available when a cardholder waited a long time before disputing. Visa’s rules allow cardholders up to 120 days from the expected delivery date to file a C08 claim, but that window has limits. If you can show the cardholder knew about the non-receipt much earlier and took no action, that timeline can become part of your argument.

This won’t apply to every case, but it’s a legitimate point to raise when the dispute date seems disconnected from when the problem would have been obvious. Gather any evidence that shows earlier awareness on the cardholder’s end.

What Weak Evidence Looks Like

A rebuttal built on a shipping label alone is not enough. Labels confirm a package was sent, not that it arrived. If you don’t have a delivery scan or confirmation at the destination address, a carrier record only takes you so far.

The same problem applies to online delivery. A payment receipt doesn’t prove the customer received access to what they purchased. You need something that shows the product or service was actually delivered to them, not just processed on your end. Gaps like these are what turn a winnable dispute into a lost one.

Organize everything into a chronological response submission. Decision-makers looking over your case are looking for a logical story, and scattered documentation makes that harder to see. If the situation is more complicated - for instance, if you’ve already issued a refund - it’s worth understanding how refunds interact with an active chargeback before you respond.

Common Mistakes That Make C08 Disputes Worse

Even with a good case, small missteps can turn a dispute response around fast. These mistakes happen on both sides - merchants who mishandle chargebacks and cardholders who weaken their own claims without realizing it.

For merchants, the most damaging move is to do nothing. Ignoring a dispute doesn’t make it go away; it just means the chargeback is automatically decided against you. With hundreds of millions of chargebacks processed every year, card networks aren’t waiting around for late replies.

Here are the dangers that hurt merchants most:

• Missing the 20-day response window and forfeiting the right to fight the claim
• Submitting vague or incomplete evidence that doesn’t directly address the cardholder’s claim
• Having no paper trail - no delivery confirmation, no signed receipt, no communication records
• Sending tracking information that only shows a shipment was sent, not that it was received
• Failing to include a clear rebuttal letter that ties the evidence together

These aren’t minor oversights. A lost chargeback hits your revenue directly and can add to your dispute ratio. Once that ratio climbs too high, card networks can flag your account or place you in a monitoring program. That’s a much harder situation to recover from.

Cardholders make mistakes too. Filing a dispute without first contacting the merchant is a common one. Banks and card networks do look at whether you tried to resolve things directly, and skipping that step can weaken your position. Submitting a dispute with only a vague explanation like “I didn’t get it” also makes it harder for the bank to rule in your favor.

Another mistake worth calling out is disputing too late. If a lot of time has passed since the transaction and you have no supporting documentation, your case gets harder to substantiate. Banks need something concrete to work with.

The thread connecting these errors is preparation - or the lack of it. Good records, quick responses, and a direct explanation of what went wrong make a real difference in how a dispute gets resolved. Sloppy cases usually produce worse results, regardless of which side is actually in the right.

Staying Ahead of C08 Before It Costs You

When a C08 chargeback does land, the response window is short and the burden of proof is on you. That means your evidence needs to be ready before the dispute arrives: signed delivery confirmations, timestamped tracking records, refund and cancellation policies, and a documented history of customer communication. The merchants who fight successfully aren’t scrambling to find proof - they’ve already built systems that generate it automatically. Understanding chargeback representment can help you prepare a stronger case before the deadline hits.

The most helpful step you can take is to audit your latest fulfillment and communication process with a single question in mind: if a customer claimed they never received this order, what could I prove and how fast could I prove it? If the answer gives you pause, that’s your starting point. Tighten the gaps, document everything, and make sure your customer service team knows how to resolve delivery problems before they become formal disputes. Most C08 chargebacks are preventable - and the ones that aren’t can still be won with the right evidence in hand. If your order ships in stages, a split shipment or partial delivery response may also be relevant to your situation.
