Accept or fight a Shopify dispute? A decision guide

Every Shopify dispute ends the same way for the first minute: a red notice, a number you did not expect, and a question that sounds simple. Do I fight this, or let it go? Most merchants answer with their gut. Some fight everything out of principle and burn their week. Others accept everything out of tiredness and quietly hand over hundreds of dollars.

Deciding whether to accept or fight a Shopify dispute is mostly arithmetic and honesty. The arithmetic tells you how likely a win has to be before your time is worth spending. The honesty tells you whether the customer is right. This guide gives you both, with a scorecard, break-even tables in A$, and the Australian Consumer Law rules that settle some cases before you start.

This guide is for you if:

You have an open dispute and are not sure whether it is worth fighting.
You tend to fight every dispute, or accept every dispute, and want a better rule.
You sell to Australian customers and want to know where consumer law changes the answer.

The 30-second answer (TL;DR)

To accept or fight a Shopify dispute, compare three things: what you can prove, what the customer is entitled to, and what the fight costs in time.
Accepting means you lose the amount and the fee, and you do no further work. Shopify does not return the fee if you lose or accept.
Fighting costs your time. If you win, Shopify returns the amount, and the fee may also come back, depending on country.
Fight when you have real proof: delivery with a matching address, messages, or a clear policy the customer saw.
Accept a chargeback when the customer is right, such as a double charge, a charge after cancellation, or a genuine fault.
In Australia, a "no refunds" sign does not protect you from a faulty goods claim, so do not build a fight on it.
A won dispute still counts toward your chargeback rate, so prevention matters more than the result of any one case.

Quick note: A dispute is not an insult, and it is not a verdict on your business. It is a transaction the customer's bank is questioning. Treat it like a small business decision: what do I know, what can I prove, and what does each option cost?

The decision at a glance

Situation	Usual best move	Why
Delivered, matching address, clear proof	Fight	Evidence answers the claim
Customer confirms they received it, but filed anyway	Fight, and ask them to withdraw	Messages are strong proof
You charged twice	Accept	Shopify's guidance is to accept a genuine duplicate
You charged after a genuine cancellation	Accept	Shopify's guidance is to accept
Faulty product, major failure, no remedy offered	Accept, or settle	The customer is entitled to a remedy
Parcel lost in transit, no delivery proof	Accept	You cannot prove delivery
Likely fraud, strong identity signals	Fight	Fulfilment, IP and history matter
Low value order, no proof	Accept	The time costs more than a likely win

What does it mean to accept or fight a Shopify dispute?

When a dispute opens you have two paths, and both are final in their own way.

Accepting means you agree the customer should keep the money. The dispute is closed as lost, and you stop work on it. Per Shopify's pages, the amount and the fee are not returned.

Fighting means you submit evidence before the due date and let the card issuer decide. Shopify says the issuer can take up to 75 days after you submit, and there is no appeal. If you win, Shopify returns the amount, and the fee may also be returned depending on country. If you lose, you lose the same amount you would have lost by accepting, plus the time you spent.

There is also a third path that many forget: doing nothing. Shopify Payments submits automatically on the due date with the information it collected. That is a fight, but a weak one. You can edit your evidence until the due date, and after you click Submit now it is locked. Our chargeback deadline guide covers the clocks.

One more point is easy to miss. If the dispute is an inquiry rather than a chargeback, you may not have to choose between accept and fight at all. A full refund can end it, and nothing has been taken yet. See the post on chargeback vs inquiry before you decide.

How much does it cost to fight a Shopify dispute?

Fighting costs time, and time has a price. A realistic pack takes about 45 minutes: opening the order, capturing tracking, exporting messages, and writing a short cover note. At A$40 an hour, that is A$30.

That is the number to carry into every dispute. A$30 is the price of the fight.

What do you gain if you win?

If you win, the disputed amount returns to you. Shopify's resolution page says the amount and the fee are returned on a win, while the overview page says the fee may be refunded depending on country. We cannot settle that difference from the pages we reviewed, so the tables below show both cases.

What do you lose if you lose?

You lose the same money you would have lost by accepting: the amount and the fee. The only extra cost is your time. You also usually lose the product, because it has already been shipped. Our post on whether you lose both the money and the product covers this.

The break-even rule: how likely must a win be?

You do not need to be certain to fight. You need the chance of winning to be high enough to cover your time.

Fight if: (chance of winning × money recovered) is greater than your time cost.

Money recovered is the amount, plus the fee if it is returned. Time cost is your A$30.

Illustration: break-even win rates in A$

Using 45 minutes at A$40 an hour, so a A$30 cost, here is the lowest win chance at which fighting pays.

Order value	Break-even if fee is returned	Break-even if fee is not returned
A$40	46%	75%
A$60	35%	50%
A$120	21%	25%
A$180	15%	17%
A$300	9%	10%
A$600	5%	5%

Read it like this. On a A$300 order you only need about a one in ten chance to make the fight worth your time. On a A$40 order, you need almost a coin flip or better, and if the fee does not come back, you need three chances in four.

These are assumed figures. If your time is worth more or the pack takes longer, the break-even rises. If you have saved templates and your records are organised, it falls, because the pack takes 15 minutes, not 45.

What if the pack takes only 15 minutes?

At 15 minutes and A$40 an hour, the time cost is A$10. The break-even on a A$60 order then falls from 35% to about 12% when the fee is returned. Preparation changes the maths. This is why storing your evidence as you go, using the chargeback evidence checklist, makes more disputes worth fighting.

Illustration: a A$180 order, three win chances

Chance of winning	Expected value of fighting (fee returned)	Expected value of accepting
20%	A$11	A$0
40%	A$52	A$0
60%	A$93	A$0

The figures show expected gain over accepting, after the A$30 time cost: 0.2 × A$205 minus A$30 is about A$11. Accepting a chargeback is the baseline, because it loses the money and costs no extra time. The numbers are estimates, not promises, and the issuer decides each case.

How do you estimate your chance of winning?

Nobody can give you a real probability, and we cannot promise any win rate. What you can do is score your evidence honestly.

The evidence scorecard

The evidence scorecard is a quick way to turn a feeling into a number.

Give one point for each statement that is true. Be strict.

The tracking shows delivered, with a date.
The delivery address matches the shipping address on the order.
You have a carrier signature, photo or safe-place note.
The customer sent a message that shows they received or used the item.
The customer had a previous undisputed order with you.
Your policy was clear and visible at checkout and supports your position.
The product page matches what you sent.
You replied to the customer's messages promptly and offered a fix.
The customer did not try to return the item or contact you before disputing.
Shopify's automatic evidence (order, IP, fulfilment) supports your account.

8 to 10 points: strong. Fight, even for modest amounts. 5 to 7 points: reasonable. Fight if the value is above your break-even. 2 to 4 points: weak. Fight only on high-value orders, or settle. 0 to 1 point: accept, or refund if it is still an inquiry.

This evidence scorecard is our own tool, not a Shopify or card network rule. It exists to make you look at your evidence before you decide.

When should you accept a dispute?

Some disputes are not worth fighting, and some are not worth fighting because the customer is right.

A genuine duplicate charge

Shopify's guidance says that if you did charge twice, accept. A fight over a real double charge wastes your time and risks your credibility.

A charge after cancellation

If a customer cancelled a subscription and you charged afterwards, accept. Shopify's guidance says so for subscription disputes.

A faulty product with no remedy offered

Australian Consumer Law applies, and the Australian Consumer Law rules are not optional. The ACCC says a failed consumer guarantee means you must offer a repair, replacement or refund, and you cannot send the customer to the manufacturer.

For a major problem, the customer chooses a refund or replacement. A major problem includes an unsafe item, one significantly different from its description or sample, one with a serious fault, or one that cannot be used for its purpose and cannot be fixed quickly. No deduction is allowed for use, the refund goes to the original payment method, and the customer may instead keep the item and receive compensation.
For a minor problem, you must repair free. A refund or replacement is not required, though you may offer one. If you fail to fix it within a reasonable time, the customer can have it fixed elsewhere and claim the cost, take a refund or replacement, or keep the item with compensation.

If the item is genuinely faulty and you refused a remedy, the card issuer may well side with the customer, and the law supports them. Accepting, or better, settling with the customer, is usually the right call.

A lost parcel with no delivery proof

If you cannot show the parcel arrived, you have little to argue. Accept, or if the dispute is still an inquiry, refund in full.

A low-value order with weak evidence

If the order is A$40 and your evidence scores 3 out of 10, the break-even is above 46%. Accept and move on.

When should you fight a dispute?

Fight a dispute when you can show what happened, and when the customer's claim does not match the facts.

Delivered orders with proof

If the parcel was delivered to the right address and you can prove it, fight. Delivery proof is the centre of a product not received case. See the guide to the evidence needed.

Customers who confirmed receipt

If the customer wrote "thanks, it arrived" and then disputed, that message is your best evidence. Fight, and ask them to withdraw the dispute with their bank. Shopify says a bank withdrawal letter takes 30 to 90 days or more, and a screenshot does not count, so submit evidence meanwhile.

Likely fraud with strong signals

If the order has a consistent IP and country, a matching address, a history of undisputed orders, and a fulfilled shipment, fight. Shopify's suggested evidence for fraudulent and unrecognized disputes is the fulfilment date and time, billing information, IP and country, and shipping and tracking.

Clear policy, honestly applied

If your refund or cancellation policy was visible and the customer is claiming something it does not allow, you can fight. Be careful: a policy cannot override consumer law, and it will not defend a faulty goods claim.

Change-of-mind disputes outside your policy

The ACCC says change of mind is not covered by the consumer guarantees, but if you offer a change-of-mind policy, you must honour it. If your policy excludes change of mind, or the return window has passed, and you applied it consistently, fighting is reasonable.

What about the customer relationship?

Money is not the only cost. A fight can sour a relationship, and a concession can build goodwill. For a customer who may buy again, a quick refund on an inquiry may be worth more than winning a chargeback.

On the other hand, repeated refunds to people who file claims that are not true can invite more claims. Use your records to see patterns. If the same customer or address appears again, the balance changes.

You can do both. Reply politely and offer a fix, and still submit evidence if the dispute is open and the due date approaches. Your message history is part of the proof.

Accept or fight a Shopify dispute: a verdict for each reason

Shopify groups disputes under eight reasons, and each has a natural lean. These are starting points, not rules. Your evidence scorecard and the break-even table still decide.

Reason	Usual lean	What tips it
Fraudulent	Fight if signals are strong	Matching address, IP and country, prior undisputed orders, fulfilment record
Unrecognized	Contact the customer first, then fight if needed	A recognisable descriptor and an order the customer can be shown
Duplicate	Accept if you charged twice, fight if the orders were separate	Two different products or dates, separate receipts
Subscription canceled	Accept if you charged after cancellation	Dated cancellation request, renewal notices, access logs
Product not received	Fight with delivery proof, accept without it	Delivered status, address match, signature, photo or safe-place note
Product unacceptable	Settle if a genuine fault, fight if the product matched its listing	Dated product page, photos, no return attempt, replacement offered
Credit not processed	Fight if the refund was issued or the policy was clear	Refund record, policy, emails showing what the customer was told
General	Contact the customer, then decide	A withdrawal letter, or proof the charge was valid

Every row comes back to one question: can you prove what you say? If yes, fight. If no, accept or settle. Our guide to the evidence checklist shows what to attach for each reason.

How do you keep a decision log so the next call is easier?

The fastest way to improve at deciding is to record what you decided and what happened. After a month you will see which kinds of disputes you win, which you lose, and which you should never have fought.

A simple decision log

Date	Order	Amount	Reason	Score out of 10	Decision	Time spent	Outcome
12 Oct	#1042	A$85	Not received	8	Fight	30 min	Pending
12 Oct	#1051	A$150	Unacceptable	3	Accept	5 min	Lost
12 Oct	#1060	A$40	Fraudulent	3	Accept	5 min	Lost

Add the cause in one line: "supplier delay", "unclear descriptor", "no tracking on cheap shipping". After ten rows the pattern is usually obvious. If your score for fought disputes is mostly 8 and above, you are picking well. If you keep fighting 3s, the scorecard is telling you something.

What should the log tell you about prevention?

A log turns disputes into a to-do list. If three of your last five accepted disputes were "delivered, customer says no", the fix is better delivery proof. If two were faulty items, the fix is a clearer returns process that matches Australian Consumer Law. If most were unrecognised charges, the fix is a better descriptor.

How does Australian Consumer Law change when you accept a chargeback?

The Australian Consumer Law gives you a simple test before you decide to accept or fight a Shopify dispute: would a refund, repair or replacement have been owed anyway? If yes, the dispute is really a request for a remedy you should have given, and accepting a chargeback may be the honest outcome.

Failed guarantee, no remedy offered: the customer is entitled to repair, replacement or refund, so accept a chargeback or settle rather than defend a refusal.
Change of mind, outside your policy: not covered by the guarantees, so you can fight if your policy was clear and consistently applied. If you advertised a change-of-mind policy, you must honour it.
Faulty, but you offered a fix that the customer ignored: your messages are evidence. Fight, and show the offer.
Customer went straight to the bank: keep your records of any attempt to contact you, or of the lack of one.

The same guide from the ACCC says you cannot send the customer to the manufacturer, and that reimbursing reasonable return costs applies when a fault is confirmed. Treat these as part of your cost when you weigh a fight, because a claim that ends with a confirmed fault carries more than the order value.

How do disputes affect your chargeback rate?

Shopify's chargeback monitoring page says the rate counts all disputes customers open on eligible Shopify Payments transactions, and a won dispute does not remove it from the rate. So accepting and fighting have the same effect on the rate. The count goes up either way.

That changes how to think about the decision. You are choosing between ways of handling a dispute that already happened. The way to protect the rate is to prevent the next one. Our guide to the Shopify chargeback rate and account health warnings explains the lines that matter, including Shopify's NDRP page, which says a rate of 1.5% or higher over 90 days can lead to automatic enrolment and a A$25 fee per dispute in Australia.

Does accepting a dispute hurt more than losing one?

Shopify's pages do not say that accepting is treated worse than losing in the rate. We found no such statement, so treat the two as equivalent for the rate, and as different only in time spent.

A worked example: three disputes, three decisions

Illustration: a busy Monday

On Monday 12 October 2026, three disputes arrive. The fee is A$25 and your time is A$40 an hour.

Dispute A: A$85, product not received. Tracking shows delivered with a photo, the address matches, and the customer emailed two days earlier asking about a return policy for the same item. Score: 8 out of 10. Break-even is about 18% with the fee returned. Decision: fight. The pack takes 30 minutes, A$20 of time.

Dispute B: A$150, product unacceptable. The customer says the item stopped working. You offered no remedy because your terms say "no refunds". The ACCC says relying on such terms for faulty goods is illegal. Score: 3 out of 10. Decision: accept or settle. If it is still an inquiry, refund in full. If it is a chargeback, accept and fix your terms.

Dispute C: A$40, fraudulent. The order was shipped to an address different from billing, with no history. Score: 3 out of 10. Break-even is above 46%. Decision: accept, and add the order to your fraud review checklist.

You fought one case and let two go. The aim is not to win every case. It is to spend your time where it pays.

What should you do after you decide to accept or fight a Shopify dispute?

If you accept a chargeback

Click accept on the dispute in your admin, or let the due date pass with no further evidence.
Record the loss, the reason and the order.
Ask what caused it. If it is delivery, tracking or policy, fix that.
Update your fraud or delivery rules if the pattern repeats.

If you fight a dispute

Build the pack using the evidence checklist.
Write a short, factual cover note.
Check file formats and sizes: PDF, JPEG or PNG, 2 MB per file, 4 MB total, one file per evidence type.
Submit at least two business days before the due date.
Record the outcome when the issuer decides.

If you settle

Contact the customer politely and offer the remedy.
If it is an inquiry, refund in full to end it.
If it is a chargeback, remember you cannot refund an open chargeback, so ask the customer to request a bank withdrawal letter and submit your evidence in the meantime.

What's different for Australian merchants?

Consumer law is part of the decision. The ACCC's guidance on repair, replace, refund shapes which fights are fair. Customers do not need original packaging. You may ask for proof of purchase. For bulky items you must pay collection, and you must reimburse reasonable return costs if a fault is confirmed. If no fault is found, you may charge collection and inspection costs with a reasonable estimate given in advance.

The customer has other routes. Consumer Affairs Victoria says customers can go to AFCA if their bank rejects a chargeback request. CHOICE reports that a retailer can end up refunding through a chargeback even if it first refused. A refusal that the law does not support can come back to you anyway.

Amounts are in A$ and the fee is A$25. Shopify's NDRP page gives A$25 for Australia for auto-resolved disputes. NAB's merchant page also states A$25, refunded on a win. Check your own admin for the regular chargeback fee.

Scheme rules sit in the background. NAB gives cardholders up to 120 days for Visa and Mastercard disputes, varying by reason, and 210 days for eftpos. Merchants respond to NAB within 30 days for Visa and eftpos and 45 for Mastercard. Your Shopify deadline is separate and shorter.

Common mistakes when deciding

Fighting out of principle

If the customer is right, fighting wastes time and weakens your record. Principle does not recover money.

Accepting out of tiredness

If you have strong proof and a modest pack, accepting can hand away real money. Use the break-even table and your evidence scorecard.

Relying on a "no refunds" sign

The ACCC says these signs and terms do not override consumer rights, and relying on them for faulty goods is illegal.

Ignoring the fee

The fee is lost if you lose or accept. Include it in the maths.

Forgetting the time

Your time is not free. Count it.

Not checking whether it is an inquiry

A full refund can end an inquiry. Check the type first.

Skipping the post-mortem

Every dispute has a cause. Write it down and fix it.

Frequently asked questions

Should I accept or fight a Shopify dispute?

Fight when you can prove delivery or use and the claim does not match your records. Accept when the customer is right, such as a double charge, a charge after cancellation or a genuine fault. In between, compare the chance of winning against the cost of your time using a break-even table.

What happens if I accept a Shopify chargeback?

If you accept a chargeback, you lose the disputed amount and the fee, and the dispute is closed as lost. Shopify's pages say the fee is not returned if you lose or accept. You do no further work, but the dispute still counts toward your chargeback rate, so look for the cause.

Do I get my money back if I win a dispute?

Yes, the disputed amount is returned. Shopify's resolution page says the fee is returned too, while its overview says the fee may be refunded depending on country. Check your admin for the result. Expect the issuer's decision to take up to 75 days after you submit.

Is it worth fighting a small dispute?

Often not, unless you can build the pack quickly. At 45 minutes and A$40 an hour, your time costs A$30, so a A$40 order needs a high chance of winning to break even. With saved templates and organised records, smaller disputes become worth fighting because the pack takes less time.

Can I fight a dispute for a faulty product?

You can submit evidence, but be careful. Australian Consumer Law gives customers remedies for failed consumer guarantees, and the ACCC says "no refund" terms do not override them. If the fault is genuine and you offered no remedy, accepting or settling is usually the better move.

Does winning improve my chargeback rate?

No. Shopify's pages say a won dispute still counts toward the rate, because the rate measures disputes opened, not who wins. Accepting and fighting have the same effect on the rate, so the lasting fix is preventing disputes through clear communication, tracking, realistic estimates and recognisable descriptors.

What if I do not respond at all?

Shopify Payments submits on the due date with the information it collected, so something is filed. That is rarely enough for a case that depends on messages or photos. You can edit evidence until the due date, and after you click Submit now it is locked.

Should I refund instead of fighting?

For an inquiry, a full refund ends it and nothing has been taken, so it can be cheaper than fighting. For an open chargeback you cannot refund, so you either respond or accept. Partial refunds do not end an inquiry, so refund in full or respond.

How long do I have to decide?

The due date is shown on the dispute, usually 7 to 21 days after filing, in your store's timezone, ending at 11:59 PM if no time is shown. Decide early and aim to submit two business days before it, because evidence is locked once submitted.
