CHARGEBACK GUIDES

Product unacceptable chargeback: how to respond on Shopify

By ChargeFix team · Updated 3 October 2026

"The item is not what I ordered" is the hardest claim to answer, because nobody can photograph a feeling. A product unacceptable chargeback turns on a comparison between what you promised and what arrived, and the bank only ever sees one side of that story unless you put the other side in front of it.

A product unacceptable chargeback is a dispute in which the cardholder says the goods arrived damaged, defective or not as described. On Shopify, you win it by showing what your listing actually promised, what you actually shipped, and that the customer never used the return or refund route you offered. In the UK, the law on goods matching their description sits behind all of it, so the strongest response and the cheapest decision are often different things.

Last updated: 3 October 2026. Written by the ChargeFix team.

The 30-second answer (TL;DR)

  • Shopify defines a product unacceptable chargeback as a customer who received the product but says it was defective, damaged or not as described. It is the claim where your listing, your photos and your policies matter most.
  • On the card networks, this category covers Visa 13.3 (not as described or defective), 13.4 (counterfeit) and 13.5 (misrepresentation). Stripe's documentation maps Mastercard 4853 and Amex C31 and C32 into the same category.
  • Shopify's list of evidence for this reason is fulfilment date and time, billing information, shipping and tracking, and product descriptions and pictures from your store. You can add more, such as packing photos and customer messages.
  • Under the Consumer Rights Act 2015, goods must match their description, and what you say about a product's main characteristics becomes part of the contract (section 11). A vague or wrong listing is a liability, not just a marketing problem.
  • Damage in transit is usually a refund and a carrier claim, not a fight, because goods stay at the trader's risk until they reach the customer.
  • A "didn't like it" claim inside 14 days is often a legal cancellation for online sales, so fighting it is weak ground.
  • The right-to-reject and six-month rules in the Act mean a defect claim months later can land on you to disprove. This is general information, not legal advice.

How strong is your position, by type of claim? (our ranking)

What the customer says Your best evidence Our view
"It arrived broken" Packing photo, carrier condition notes Usually refund, then claim from the carrier
"It is defective" Inspection record, customer contact, troubleshooting Depends on timing and the product
"It is not as described" Dated listing, your photo of what shipped Often defensible if the listing is accurate
"It is fake" Supplier invoices, authenticity records Defensible only with paperwork
"I changed my mind" A policy that excludes it, lawfully Weak inside 14 days for most online sales

What is a product unacceptable chargeback?

A product unacceptable chargeback is a dispute filed because the customer says the goods they received were not acceptable. Shopify's own definition is that the customer received the product but says it was defective, damaged or not as described. The cardholder's bank then pulls the money back from your Shopify Payments balance while it decides who is right.

On Shopify Payments in the UK, that means the disputed amount plus a £10 fee is debited when the chargeback opens. Both come back only if you win. The merchant has between 7 and 21 days to respond, depending on the case, and the bank may take up to 75 days to review after that. Our post on how long a Shopify chargeback takes walks through the full timeline, and the Shopify chargeback fee explained covers the money side.

What makes this reason different from the others is where the argument happens. A fraudulent claim is about who made the payment. A product not received claim, which we cover in our UK carriers and proof post, is about whether a parcel arrived. A product unacceptable claim is about quality and description, which are matters of degree. Two reasonable people can look at the same jumper and disagree about whether it is "not as described".

That is why this dispute rewards preparation more than most. You cannot prove a product is perfect after the fact. You can prove what you said about it, what you sent, and what the customer did or did not do about their complaint.

Which card network codes sit under product unacceptable?

Shopify groups many network codes into this one label. Based on Stripe's published reason code documentation, which describes the same card network rules that sit behind Shopify Payments, the main ones are:

Network Code Network's name for it
Visa 13.3 Not as described or defective merchandise or services
Visa 13.4 Counterfeit merchandise
Visa 13.5 Misrepresentation
Mastercard 4853 Defective or not as described
American Express C31 Goods or services not as described
American Express C32 Goods or services damaged or defective

You will not usually choose between these. Shopify shows the reason as "Product unacceptable" and you answer it. The code matters for one practical reason: counterfeit and misrepresentation claims are about authenticity and honesty, so the evidence is different. For counterfeit, Stripe's guidance points to supplier records, invoices and certificates. For the other codes, it points to listings, delivery records and customer communications.

We did not find a Shopify page that lists every code behind each reason, so treat this table as the networks' categories as Stripe documents them, not as an official Shopify mapping.

Why is this the hardest chargeback to win?

It is not always the hardest to win, but it is the one where winning feels least like arithmetic. Three things make it awkward.

First, the claim is subjective. "Defective" and "not as described" depend on what the customer expected. A bank reviewer cannot hold the item. They read your evidence and the customer's statement and decide which is more believable.

Second, you carry the burden of showing your own description was fair. If your listing says "premium leather" and the customer sends a photo of something plastic-looking, your dated listing and supplier invoice have to do the talking. If the listing is loose, the bank has little reason to side with you.

Third, the customer often has a legal right to a remedy anyway. In the UK, goods must match their description. If the customer has a genuine complaint inside the time the law allows, a refund may be what you owe regardless of the chargeback. Fighting a claim you would lose in a county court is a poor use of £10 and an afternoon.

None of that means you should always refund. It means you should sort claims into the ones you can answer and the ones you cannot, quickly, and put effort only where evidence exists. The next sections show how.

If you handle a handful of these a year, a spreadsheet and the patterns in this post will serve you well. If you handle dozens, the sorting and pack-building starts to eat real hours, and that is the repetitive part ChargeFix is being built to take on, though it is not live yet and nothing here is a promise about results.

What does Shopify's evidence list actually say?

Shopify's help centre lists what to provide for a product unacceptable chargeback. It names:

  • fulfilment date and time
  • billing information
  • shipping and tracking details
  • product descriptions and pictures from your store

Notice what is missing from that list: anything about the condition of the product when it left you, and anything about what the customer said afterwards. Those are the two things that most often decide a quality dispute, and you have to add them yourself.

Shopify's upload rules apply as for any dispute. Files must be PDF, JPEG or PNG, one file per evidence type, 2 MB or less each and 4 MB in total, and external links are not accepted. When you press Submit, the response is locked, so finish everything before you do. Our post on what Shopify submits for you explains which of those details Shopify may attach itself and which it leaves to you.

One point we could not verify: whether Shopify's automatic product description and picture attach the version of your listing as it stood on the order date, or the version live when the dispute was filed. Do not rely on it. If you have edited the listing since the sale, take your own dated copy.

What does Stripe's guidance add?

Stripe's documentation is useful here because it is explicit and the networks behind it are the same. For product unacceptable disputes, its examples include:

  • the listing or description as presented at the time of purchase, screenshots or archived versions
  • order and fulfilment records with timestamps
  • customer communications, specifically showing that the customer did not report the issue before filing, or that you offered troubleshooting
  • return and refund terms, and the customer's agreement to them
  • photos of the item before shipment, including serial numbers or inspection tags
  • inspection or quality control records for damage and defect claims

That list is a better checklist than Shopify's short one. Use the Shopify items as your base and add the Stripe-style items that fit the claim.

How do you triage a product unacceptable claim in ten minutes?

Before you collect anything, decide which of five situations you are in. The answer changes everything that follows.

Step 1: What exactly is the customer complaining about?

Open the chargeback and read the customer's reason if one is shown, then search your inbox, contact form and helpdesk for the customer's name, email and order number. Sort the claim into one of these:

  1. Damaged in transit. The item arrived broken or crushed.
  2. Defective. It arrived or later became faulty.
  3. Not as described. It differs from the listing in size, colour, material, quantity, features or quality.
  4. Wrong item. You shipped something other than what was ordered. This is a fulfilment error, not a description problem.
  5. Counterfeit or misrepresented. The customer says it is not genuine.

Notice that number 4 is not really a dispute about description at all. If you sent the wrong item and your pick record shows it, you have no defence and no reason to spend time on one.

Step 2: Did the customer contact you first?

This is the single most important fact. A customer who emailed you, got no reply or an unhelpful one, and then filed a chargeback has a reasonable story. A customer who never contacted you and went straight to their bank has bypassed your process, and that is a fact you can put in front of the reviewer.

Stripe's guidance for these disputes returns to this point repeatedly: where the customer did not report an issue before filing, messages showing acceptance, and policies the customer bypassed, support the merchant's case. You can only use the point if your records show it either way, which is why the contact log matters.

Step 3: Is the listing accurate to what you shipped?

Open the listing as it stood on the order date. Read it as a stranger would. If the customer says "the colour is wrong" and your photos show a different shade from what you packed, no amount of policy wording rescues you. Be honest with yourself at this stage, because the bank will be.

Step 4: How old is the order?

A complaint 3 days after delivery and one 5 months after delivery are different disputes. Under the Consumer Rights Act 2015, the short-term right to reject faulty goods runs for 30 days from delivery (section 22), and a six-month presumption applies to non-conforming goods (section 19). We explain both below. For triage, the rule of thumb is simple: the older the order, the more the law favours the customer on a genuine defect.

Step 5: Does the maths support a fight?

Work out the break-even win rate using the method from our cost of a chargeback post. On Shopify Payments UK, the break-even is your extra time divided by the order value plus £10. A section below applies it to three realistic orders.

What does UK law say about goods that are not as described?

You do not need to be a lawyer to run a shop, but you do need to know that the Consumer Rights Act 2015 is the background to every one of these disputes. This is general information, not legal advice, and you should check the Act itself or take advice for a specific case.

Goods must match their description (section 11). The Act says goods must match any description given to the consumer, and information you give about a product's main characteristics is treated as part of the contract. In plain terms: what your listing says is a promise.

Remedies come in tiers (section 19). The Act sets out the consumer's remedies when goods do not conform, including the right to reject, repair, replacement and price reductions. It also sets a presumption: goods that do not conform within six months of delivery are taken not to have conformed on delivery, unless the trader shows otherwise. That shifts the burden to you in that window.

The short-term right to reject lasts 30 days (section 22). The legislation says the time limit is the end of 30 days beginning with the first day after ownership or possession has passed, delivery has happened and any installation is done. A consumer who does not use it in that time loses it, unless you both agree otherwise, and an agreement that would cut it short is not binding on them.

Online buyers can usually cancel within 14 days. Under the Consumer Contracts Regulations 2013, a consumer who buys at a distance generally has a right to cancel without giving a reason, and regulation 34 requires you to reimburse within 14 days of being informed of the withdrawal, or, where you collect nothing, 14 days after you receive the goods back or evidence of return, whichever is earlier. You can deduct for loss in value caused by handling beyond what is needed to inspect the goods. There are exceptions, such as personalised items, and you should check the current rules at gov.uk before you rely on one.

Why this matters to a chargeback. If a customer files a "not as described" dispute because they simply changed their mind on day 6, the bank may see a customer exercising a right that exists in law. Winning by showing your return policy says "no returns" will not help if the policy cannot lawfully remove that right. We do not recommend wording that tries to.

A fair summary: if the product is genuinely wrong, broken or unfit, UK law already points to a refund, repair or replacement. If the product is as described and in good condition, your listing and your photos protect you. The grey middle is where the evidence pack earns its keep.

How do you respond to a product unacceptable chargeback on Shopify?

Here is the process for a Shopify product unacceptable chargeback, in the order we would do it. It assumes you have already triaged the claim.

  1. Set an internal deadline two working days before Shopify's due date. Late submissions are the most avoidable loss.
  2. Gather the four Shopify items: fulfilment record, billing details, tracking, and your product description and pictures.
  3. Add your own proof of condition: photos taken at packing, a quality check note, serial numbers if the product has them.
  4. Add the customer's history with you: every message, with dates, including anything where they accepted the item, thanked you or did not mention a problem.
  5. Add the policy evidence: the return and refund policy as shown at checkout, and the order confirmation or checkout screen that links to it.
  6. Write a one-page cover note that links the exhibits to the claim.
  7. Convert, compress and name files so each evidence type is a single PDF, JPEG or PNG within the limits.
  8. Submit and check the status says Submitted. Remember, Submit locks the response.

Our guide to what Shopify submits for you covers the fields in the Shopify admin. This section is about what goes in them.

What should the cover note say?

A reviewer reads dozens of these. The note is the only part that tells them what to look at. Keep it to one page, factual and dated. Here is a template for a "not as described" claim.

Chargeback response: order #[number]

The customer claims the item was not as described. We disagree, for these reasons.

  1. What we promised. The listing, as it appeared on [order date], described the item as [exact wording] and showed [what the photos showed]. See Exhibit A.
  2. What we sent. The order was fulfilled on [date]. The packing photo taken before dispatch shows [item, colour, quantity]. See Exhibit B.
  3. What was delivered. Tracking shows delivery to the order address on [date]. See Exhibit C.
  4. What the customer told us. The first contact we have from the customer about this order is [the chargeback / an email dated X]. We replied on [date] offering [return, replacement or refund]. The customer [did not respond / declined]. See Exhibit D.
  5. Our policy. The return policy, linked at checkout, says [summary]. See Exhibit E.

We ask that the dispute be decided in our favour.

Change the second-last line to fit the facts. If the customer never contacted you, say so plainly. If they did and you did not reply for a week, do not claim otherwise. A response that contradicts your own records loses credibility fast.

What should the response look like for damage and defect claims?

Replace point 2 with a condition record: "The item was inspected and photographed before dispatch on [date]; photos show no damage." Add the carrier delivery record, and if the customer's photo shows packaging damage, say what the packaging was and why you believe it was adequate. Do not argue with the photos. Argue about the sequence of events.

What evidence wins a "not as described" dispute?

"Not as described" is the cleanest claim to defend when your listing is accurate, because the evidence is a comparison and you hold both halves.

Exhibit A: the listing as it stood on the order date

This is the foundation. If you edit a listing after a sale, the old text is gone unless you saved it. Three ways to protect yourself:

  • Take a dated screenshot of any listing that gets a significant edit.
  • Keep a simple change log: product, date, what changed.
  • For high-value lines, save the page as a PDF each time it changes.

Screenshots help, but make sure they show the whole description, the photos, any size or material notes and the price. Crop out nothing the customer relied on.

Exhibit B: what you actually packed

A photo of the item in its packaging, taken at dispatch, shows what left your hands. For made-to-order or higher-value goods, add the label, serial number or inspection tag in shot. It takes about ten seconds per parcel. Even doing it only for orders over a set value, say £75, covers most of your exposure.

Exhibit C: the comparison

Place the listing photo next to the packing photo with a short caption. Do not claim they are identical if they are not. Say what is the same and what differs, and why the difference is within what the listing disclosed, for example "colour shown on screen may vary slightly".

Be careful with that last phrase. A generic screen colour disclaimer helps a little with minor shade variations. It does not rescue a listing that shows red and a parcel that contains orange.

Exhibit D: customer communications

Every message, in date order. Pay attention to what the customer did not say. If they wrote "love it" or left a good review before filing, that is worth including. If they asked about delivery but never mentioned a problem, that is also relevant.

Exhibit E: policy and checkout terms

Your return and refund policy as it appeared at checkout, and evidence that the customer agreed to it or had a clear route to it. Policy evidence is only as good as its visibility. A policy hidden at the bottom of a page the customer never saw is a weak exhibit.

How do you handle damage and defect claims?

Damaged in transit

Goods stay at the trader's risk until they are in the consumer's possession (Consumer Rights Act 2015, section 29). If an item arrived broken because the carrier handled it badly, the customer is entitled to a remedy from you, and you claim from the carrier. Fighting a chargeback on this claim usually fails for the same reason a fight over a lost parcel does: the bank is looking at a customer who paid and did not get working goods.

The exception is the claim that does not match the facts. If the customer's photo shows an undamaged item and a damaged box, or the tracking shows delivery of a different parcel, you have something to argue. Otherwise, the practical path is to refund where the damage is evident, claim from the carrier using your packing photos, and improve the packaging.

We covered how the same risk rule works for lost parcels in our carriers and proof post, so we will not repeat the detail here.

Defective

For a defect claim, your best evidence is a record that you tested or checked the item, plus proof that the customer did not come to you. Stripe's guidance mentions technical support logs showing troubleshooting attempts or the customer's lack of engagement. Where you did offer a fix and the customer ignored it, say so with dates.

If the claim lands inside the 30-day window and the fault looks genuine, a refund or replacement is what the law expects, and the chargeback becomes a question of how much extra the fight will cost you. If the claim lands between 30 days and six months, the six-month presumption means you may have to show the fault was not there at delivery. If it lands after six months, the burden is more likely on the customer.

That timeline is not a reason to concede every old claim. It is a reason to know what you are up against before you commit hours to one.

Counterfeit or misrepresented

If a customer says your product is fake, the only credible answer is paperwork: supplier invoices, certificates of authenticity, distributor agreements. Stripe's documentation lists exactly those. If you cannot produce them, this is not a claim to fight, and if your product is a copy being sold as the original, it is not a claim you should be fighting at all.

Digital goods and services

If the product was digital, such as a download, licence or service, the evidence changes. Shopify's help asks for activity logs for digital products in related reasons, and Stripe's guidance points to usage logs showing logins, downloads and use after purchase. A customer who downloaded the file three times and then claimed it did not work has a harder story to tell.

Should you fight, refund or offer a return?

Every Shopify product unacceptable chargeback ends in one of three decisions, and the evidence you hold decides which is sensible. This is where most of the money is decided. Your options once a chargeback opens, and a customer has not yet escalated, are limited by one fact: after a chargeback starts, you cannot refund it through Shopify. The amount and fee have already been debited, so a separate refund to the customer risks paying twice. Do not refund a customer outside the dispute process once a chargeback is open unless you have confirmed how it will be treated.

The better moment to act is before a chargeback exists. When a customer emails to complain, you have a window in which a refund, return or replacement removes the reason to dispute. A prompt reply costs a fraction of a chargeback. Shopify's own guidance on preventing disputes recommends refunding immediately when a customer asks, and keeping a clear, findable return policy.

What does the maths say?

We use the same method as our cost of a chargeback post. On Shopify Payments UK, the extra cost of fighting, set against accepting the loss, is just your extra time, valued at an hourly figure. The amount and the £10 fee come back if you win and are gone either way if you do not, so they sit on both sides of the sum. Break-even win chance is therefore:

Break-even = extra time cost ÷ (order value + £10)

The assumptions below are illustrations, not measured rates. We assume £20 an hour, 0.5 hours to build a prepared response, 2.5 hours for an unprepared one, and 0.25 hours to accept. That gives an extra time cost of £5 when prepared and £45 when not.

Order value Break-even if prepared Break-even if unprepared
£30 12.5% 112.5% (never worth it)
£60 7.1% 64.3%
£120 3.8% 34.6%
£240 2.0% 18.0%

The first lesson is the gap between the columns. A prepared response with a packing photo, a saved listing and a contact log has a break-even of a few per cent. An unprepared one needs a coin-flip chance on a £60 order. Preparation is not a nicety, it is what makes fighting rational at all.

The second lesson is that these break-evens assume you value your time and ignore the effect on your dispute record, which Shopify counts whether you win or not. Our chargeback rate post explains why a won dispute still counts toward your rate.

Three worked examples

These are illustrations with invented orders. The win chances are assumptions, not measured results, and the bank always decides.

Example 1: the cracked mug, £35 (refund)

A customer orders a ceramic mug at £35 and files a product unacceptable chargeback saying it arrived broken. The carrier's delivery scan is clean. The customer's email, which arrived two days earlier and which you missed, includes a photo of a cracked handle. Your packing photo shows an intact mug in decent packaging.

Your evidence proves what you shipped, not what arrived. The bank sees a customer with a photo, a prior complaint you did not answer, and goods at your risk until delivery. Even a prepared response has a poor chance, and a loss costs £35 plus £10, which you cannot recover.

The sensible move is to accept, take the £45 hit, claim from the carrier if the packaging was at fault, and reply to complaint emails within a working day from now on. Cost of the lesson: £45. Cost of fighting and losing: £45 plus an hour of your time and a worse record.

Example 2: the jacket in the wrong shade, £120 (fight)

A customer orders a £120 jacket listed as "navy" and files a not-as-described chargeback saying it is black. You check. Your dated listing screenshot says "navy" with three photos showing a clear dark blue. Your packing photo, taken at dispatch, shows the same dark blue against the label. The customer never contacted you, and your return policy was linked at checkout with a 30-day return window.

This is a response you can build in half an hour. The break-even if prepared is 3.8%. With a listing, a packing photo, no prior contact and a policy the customer bypassed, a 50% chance is a fair illustration. On that assumption, fighting recovers an expected £65 (half of the £120 order plus the £10 fee, so half of £130) for about £5 of extra time.

Fighting is clearly worth it. Offering the customer a return label alongside the response, if the process allows, would also protect the relationship.

Example 3: the faulty blender, £240, five months later (usually refund)

A customer orders a £240 appliance and files a chargeback at five months saying it stopped working. They never contacted you. Your listing was accurate and the delivery was clean.

The break-even if prepared is 2%, so on pure maths a fight looks cheap. But the Act's six-month presumption means a fault that appears inside six months is taken to have been present at delivery unless you show otherwise, and you have no inspection record to rebut it. A bank may not apply UK law the way a county court would, but a record of your own that says "no testing done" does not help.

A more realistic route: contact the customer, offer a repair or replacement under the Act, and if they have already gone to their bank, weigh a fight only if your pack includes testing evidence, serial number records and proof they ignored a repair offer. Without those, it is a refund.

We use these illustrations to show how the same method gives different answers, not to suggest particular win rates. Keep your own log of outcomes by reason and use it in place of our assumptions as soon as you have a dozen or so cases.

Is there a fight you should never take?

A few patterns are not worth the effort, whatever the pack looks like.

  • Your own error. You shipped the wrong item, the wrong size or a missing part, and your records show it.
  • A listing that was wrong. The photo shows a feature the product does not have, or the description omits something material.
  • Customer contacted you and you ignored them. A documented, unanswered complaint is the worst fact you can put in front of a reviewer.
  • Change of mind inside 14 days. If the customer is entitled to cancel, a chargeback is a messy way of doing so, but fighting it is hard to justify.
  • A genuine safety or authenticity issue. If the product might be unsafe or fake, a refund and a hard look at your supplier is the only responsible answer.

For these, accept the loss, fix the cause and move on. Each of the patterns above is an input to your process, not just a lost sale.

How do you write return policy wording that helps in a dispute?

Policy wording is a common weak point. Two things have to be true: the policy is easy to find, and it says something a reviewer can use.

What strong wording looks like

  • A clear return window, stated in days, for example "30 days from delivery".
  • How to start a return, with an email address or form, so the customer's first step is with you.
  • Who pays for return postage in each case: faulty items versus change of mind.
  • How and when refunds are made: same payment method, within a stated number of days of receiving the item back.
  • A line for damaged or faulty goods: "If your item arrives damaged or faulty, contact us within X days with a photo and we will arrange a refund, replacement or repair."

What weak or risky wording looks like

  • "No returns" with no exceptions. It cannot lawfully remove statutory rights for faulty or misdescribed goods, and a reviewer may treat it as a sign you do not take complaints seriously.
  • A policy in a PDF behind three clicks.
  • A policy that contradicts the listing, for example a product page that promises "free returns" while the policy charges for them.

Where the policy has to appear

Stripe's guidance asks for the policy as agreed at checkout. In practice, that means a visible link in the checkout flow and on the order confirmation email. Take a screenshot of the checkout page showing the link, and keep a copy of the confirmation email template. It takes five minutes and gives you an exhibit most merchants never have.

What should you do at dispatch so you are ready?

Almost everything that wins a product unacceptable chargeback is created before the dispute exists. A short routine, applied to orders above a value you choose, covers it.

  1. Photograph the item in its packaging before sealing the parcel, with the order number visible.
  2. Record serial numbers or batch codes where the product has them.
  3. Check against the listing: colour, size, quantity, included parts. Fix mismatches before shipping.
  4. Save the listing if you have edited it recently.
  5. Reply to every complaint within one working day, and log it.
  6. Keep everything for at least 120 days after delivery. That is the debit card chargeback window MoneyHelper describes for the UK, and it is the minimum sensible period for keeping the file. Section 75 claims on credit cards, for items between £100 and £30,000, can run longer, so keep high-value order files longer.

You do not need a system for this. A folder per month, a naming convention and a habit will do. The point is that the evidence exists when you need it.

How do you reduce these disputes in the first place?

Prevention beats representment, and the cheapest prevention is clarity.

  • Photograph the product honestly. Show scale, texture and colour in natural light. Add the dimensions in the description, not only on the image.
  • Say what is not included. Many "not as described" claims come from assumed accessories.
  • Make support easy. A visible email address and a reply inside a day turns many angry customers into refunds you control, not chargebacks you do not.
  • Refund fast when the customer is right. Shopify's prevention guidance says to refund immediately on request. A £35 refund today is cheaper than £45 and a record mark in six weeks.
  • Use a recognisable billing descriptor. Shopify says Shopify Payments merchants can set the billing statement text to the store name or domain. That prevents the unrecognised-payment disputes that sometimes turn into product disputes when a customer is confused about the purchase.

What's different for UK merchants?

A few UK specifics matter if you sell here, which is the market this series is written for.

  • Statutory rights are not optional. The Consumer Rights Act 2015 applies to consumer sales regardless of your policy wording. Do not copy a US-style "all sales final" policy.
  • The fee is £10 on Shopify Payments. It is returned if you win. Stripe's UK dispute fee structure is different, and our Stripe dispute fees post covers it.
  • Banks work to UK and network timelines. MoneyHelper describes a 120 day window for debit card chargeback claims, and says banks should tell the customer the outcome within eight weeks. That helps you judge when a late complaint is likely to become a dispute.
  • Section 75 claims can run in parallel. For credit card purchases between £100 and £30,000, the customer may claim against the card provider as well. Your evidence still helps.
  • Keep the evidence in a form you can export. Shopify's file limits are tight, so build your pack in PDF with the exhibits pre-compressed.

For the bigger picture of how these disputes fit together, our UK Shopify chargebacks guide is the hub for the series.

Common mistakes

  • Not answering the customer's first email. It turns a refund into a chargeback and a documented failure to respond.
  • Arguing the quality instead of the process. Reviewers rarely decide whether a product is "good enough". They decide whether the merchant described it fairly and offered a remedy.
  • Submitting a pack with no listing evidence. Shopify's product description and photos may be there, but you cannot be sure which version. Add your own.
  • Refunding outside the dispute. After a chargeback opens, a separate refund can leave you paying twice. Pause and check before you send money.
  • Using a "no returns" policy as your defence. It is weak evidence and may be unenforceable for faulty goods.
  • Missing the deadline. Shopify files a thin response from system data on the due date if you do not respond, and you cannot add to it afterwards. See our post on what happens if you don't respond.
  • Fighting for the principle. If the maths and the evidence do not support it, accept and fix the cause. Our post on whether a chargeback is worth fighting gives a fuller decision tool, and our post on whether you can win a Shopify chargeback explains why headline win rates are unreliable.

What should you do next?

  1. Open your last three quality-related disputes and sort each into the five claim types above.
  2. Check your listings: do the photos, colours and sizes match what you ship?
  3. Add a packing photo step to orders above a threshold you choose.
  4. Rewrite your return policy using the strong wording above, and make it visible at checkout.
  5. Set a one-working-day rule for replying to complaint emails.
  6. Start a simple log of each product unacceptable chargeback: reason, evidence you had, outcome.

If you want help turning those records into a response each time, ChargeFix is being built for that, with flat, fixed pricing. It is not live yet.

FAQ

What is a product unacceptable chargeback?

It is a dispute in which the cardholder tells their bank the goods arrived defective, damaged or not as described. The bank debits the amount while it decides, and on Shopify Payments in the UK that includes a £10 fee. Both return only if you win, so your response should show what you promised, what you shipped and what the customer did about it.

How do I win a product unacceptable chargeback on Shopify?

Show that your listing was accurate and that you shipped what it described. Include the product description and pictures as they stood on the order date, a photo taken at packing, delivery proof, the customer's messages and the return policy shown at checkout. Add a one page cover note that links them. Evidence improves your odds but cannot guarantee a win, because the bank decides.

What is the difference between product unacceptable and product not received?

Product not received means the customer says nothing arrived, so the evidence is delivery proof. Product unacceptable means the customer got the item and says it was defective, damaged or not as described, so the evidence is your listing, your packing records and your communications. The first is a question of fact, the second of description and quality.

Should I refund a customer who says the item is not as described?

If your listing was wrong, you shipped the wrong thing, or the item is genuinely faulty, yes. UK law expects goods to match their description, so a refund is usually the sound answer, ideally before a chargeback opens. If the item is as described and the claim looks weak, you may have grounds to fight, but only when you can prove it.

Can a customer file a chargeback just because they changed their mind?

They can file it, and some do, but online buyers in the UK generally have a 14 day right to cancel under the Consumer Contracts Regulations 2013, with exceptions such as personalised goods. A change-of-mind chargeback inside that window is hard to defend. Check the exceptions at gov.uk before you rely on one.

How long do I have to respond?

Shopify gives between 7 and 21 days to respond, depending on the case, and the response is locked when you submit it. If you do not respond, Shopify files a thin response from system data on the due date and nothing can be added afterwards. Set an internal deadline two working days earlier.

Does a "no returns" policy protect me from this chargeback?

Not reliably. A policy cannot lawfully remove a consumer's statutory rights for faulty or misdescribed goods, and a reviewer may read an absolute "no returns" line as a warning sign. A clear, fair policy with a visible route to a remedy is a much stronger exhibit.

Is it worth fighting a small product unacceptable chargeback?

Only if you can prepare cheaply. On our illustrative assumptions of £20 an hour, a prepared response needs only a few per cent chance of winning to break even on a £60 order, but an unprepared one needs about 64%. Keep packing photos and listing records so that the fight is cheap, and refund where your own records are against you.
