Chargeback app vs doing it yourself: what it costs in time and money

Every chargeback app asks you to pay for something you can do yourself on a quiet afternoon. The honest question is whether your afternoons are quiet, and what each hour of them is worth.

The chargeback app vs doing it yourself choice comes down to three numbers: minutes per dispute, disputes per month and what the tool charges. For most stores with only one or two disputes a month, doing it yourself costs less. From about three a month, a chargeback app can start to pay for itself on time alone.

This guide is for you if:

• You get disputes on your Shopify store and cannot tell whether a paid app is worth it or just another subscription.
• You respond to chargebacks by hand today and want to know what that really costs in dollars and weekends.
• You are comparing a flat monthly fee with a percentage of recovered money and want the sums done in A$.

The 30-second answer (TL;DR)

• The chargeback app vs doing it yourself decision is a break-even sum, not a matter of taste. Minutes saved, disputes per month and the chargeback app's price are the inputs.
• One third-party source puts a by-hand packet at 20 to 45 minutes. I could not verify that figure for Shopify stores, so time your own.
• At A$40 an hour and a 20 minute saving, a flat A$39 monthly app breaks even at three disputes a month on time alone.
• With one dispute a month, the same app needs to win about 1 extra dispute in 6 to pay for itself. That figure is an assumption, not data.
• Shopify's A$25 fee comes back with the amount if you win, so each extra win is worth the order value plus A$25.
• Percentage pricing costs nothing in a month with no wins, but it takes a cut of wins you might have made yourself.
• No app decides the outcome. Shopify says it does not decide disputes, and strong evidence does not guarantee a win.

Quick note The misunderstanding: a chargeback app will win more of your chargebacks. The correct version: a chargeback app can save you hours and improve how your evidence is prepared, but the bank decides, and you should price the tool on time saved first and extra wins second.

Chargeback app vs doing it yourself at a glance

Question	Doing it yourself	Using a chargeback app
What you pay	Your time and nothing else	A flat fee, a percentage of recovered money, or a free tier, depending on the chargeback app
Time per dispute	Often the longest part: finding orders, proof and writing	Less, because the packet is pre-filled, though you still review it
Evidence quality	As good as your records and your patience that day	More consistent, if the chargeback app reads your order, carrier and customer data
Deadline risk	You track it yourself	Alerts help, but the deadline is still yours
Control	Total	Varies, so ask whether you approve each filing
Data you hand over	None	Store data through app permissions you should check
Best for	One or two disputes a month, or a very unusual case	Several a month, or a store where nobody has the hours

What does the chargeback app vs doing it yourself choice really come down to?

It comes down to the price of an hour and the number of disputes. If a dispute takes you 30 minutes and your time is worth A$40 an hour, each one costs A$20 by hand. A chargeback app is worth paying for when its price is lower than the time and extra wins it gives back.

Notice what is not on that list. It is not whether the chargeback app has a clever name or a long feature page. Shopify's own help centre is blunt about the limits: Shopify does not decide the outcome of a dispute, and strong evidence does not guarantee a win. The bank rules on what you send. A tool changes who does the work and how tidy the packet is. It does not change who makes the decision.

So the sensible way to approach the chargeback app vs doing it yourself question is to price it like any other business expense. Work out what you spend today, work out what the chargeback app would cost, and see which side is cheaper at your volume. The rest of this guide gives you the formulas and three worked A$ examples. If you have not worked out what each dispute costs you, start with the chargeback cost calculator, then come back.

What does doing it yourself actually involve?

Doing it yourself means collecting your own evidence for every dispute: the order record, proof of delivery, the customer's history, your policies and a short written response. You then submit it before the deadline. None of it is hard, but all of it takes time, and the time repeats with every dispute.

Here is the by-hand routine, in the order most merchants do it:

1. Open the dispute in your Shopify admin and note the reason, the amount and the deadline.
2. Find the order and read the customer details, the payment details and the fulfilment record.
3. Get proof of delivery from the carrier, or from the order timeline if the tracking is there.
4. Pull anything that shows the customer received or used what they bought, such as messages, login records or signed delivery.
5. Collect your policies: shipping, returns, terms and a screenshot of the checkout where relevant.
6. Write a short response that answers the specific reason, in plain facts.
7. Save the evidence in Shopify before the deadline, because Shopify submits what is saved on the due date.
8. Log the outcome so you can see your pattern later.

Shopify's help centre says that for a dispute that is still open you can add evidence, and that the due date is typically 7 to 21 days after the dispute is filed. If no time is shown, the deadline is 11:59 PM on the date shown. It also says Shopify submits the evidence you have saved on the due date. That last point matters for the chargeback app vs doing it yourself comparison, because it means a half-finished packet still goes out if you ran out of time.

What does a by-hand packet look like?

A by-hand packet is a handful of files and one written response. For a product not received dispute, it usually holds the order summary, the tracking or carrier proof, the delivery address match, your shipping policy and a short explanation. The kit below is a reasonable starting point, and it works the same whether you use a chargeback app or not.

EVIDENCE PACKET KIT (copy and keep)

Dispute reason (as shown by Shopify): ______________________
Order number and date: ______________________
Amount disputed (A$): ______   Deadline (date and time): ______________

[ ] Order summary (items, prices, shipping address, billing address)
[ ] Payment details (card country, address check result if shown)
[ ] Proof of delivery or proof of use (carrier page, signature, access log)
[ ] Customer messages (all of them, in date order)
[ ] Shipping policy, returns policy, terms (as they stood on the order date)
[ ] Checkout screenshot showing the policies link, if relevant
[ ] Any earlier successful orders from this customer
[ ] Short response (5 to 8 sentences, facts only, dates included)

Saved in Shopify by: ______________   Internal cutoff (deadline minus 2 days): ____________

Where does the by-hand time go?

Most of it goes to hunting, not writing. Finding the right order, the carrier page and the old message takes longer than describing them. Typing the response is usually the fastest step. That is why tools that pre-fill the packet claim time savings, and why your own records matter as much as your own effort.

How long does one dispute take by hand?

One third-party source I found puts a by-hand packet at 20 to 45 minutes. I could not verify that for Shopify stores, so treat it as a range to test, not a fact. The only number that counts is yours, and you can get it by timing your next three disputes with a phone timer.

Here is what that range costs at three hourly values. The hourly value is the part you control: use what an hour of your time is worth to the store, not what you would like to pay yourself.

Minutes per dispute	At A$30 an hour	At A$40 an hour	At A$60 an hour
20	A$10.00	A$13.33	A$20.00
30	A$15.00	A$20.00	A$30.00
45	A$22.50	A$30.00	A$45.00
60	A$30.00	A$40.00	A$60.00

Multiply by your monthly count and the number grows quickly. At 30 minutes and A$40 an hour:

Disputes per month	By-hand time	Cost at A$40 an hour
1	30 minutes	A$20
3	1.5 hours	A$60
6	3 hours	A$120
10	5 hours	A$200

Those are illustrations, not averages. A store selling made-to-order goods with messy fulfilment records will spend more, and a store with clean tracking and one product will spend less. The point of the chargeback app vs doing it yourself test is to replace my numbers with yours.

What should you time?

Time the whole job, start to finish, including the hunt for the order and the carrier page. Use this small log for your next three disputes. If you only time the typing, you will make doing it yourself look cheaper than it is.

DISPUTE TIME LOG

Dispute / order: ____________   Reason: ____________   Amount: A$______
Minutes finding order and customer details: ______
Minutes getting proof of delivery or use:    ______
Minutes collecting policies and screenshots:  ______
Minutes writing the response:                 ______
Minutes saving, checking and logging:         ______
TOTAL MINUTES: ______   x hourly value (A$____ / 60) = A$______

How do chargeback apps charge?

Chargeback apps usually charge in one of three ways: a percentage of the money recovered, a flat monthly fee, or a free plan with limits. I saw all three in search results on 14 October 2026. I did not open pricing pages, so check each chargeback app's current terms yourself.

Pricing model	How it works	Cost in a month with no wins	Cost in a month with wins	Watch for
Percentage of recovered	You pay a cut of money won back	A$0	Grows with every win	The cut may apply to wins you would have made anyway, and you should ask whether it applies to the fee too
Flat monthly	Same price every month	The full price	The same full price	Paying in months with few or no disputes
Free plan	No charge up to a limit	A$0	A$0 up to the limit	What the limit is, and what happens when you pass it

Two vendors I saw publish a percentage, 25% and 20%. A third listing showed a flat monthly price with a free trial. I am quoting these as examples of the shapes you will meet, not as a price list, and I am not naming the vendors. Prices change, and the form of the pricing matters more than the number.

Which pricing model suits which store?

A store with few disputes often does better on a percentage model, because it pays nothing in quiet months. A store with steady disputes often does better on a flat fee, because the cost stops growing as it wins more. A free plan is worth trying first if its limits fit. Illustration 3 below puts numbers on this. If you want a closer look at the two main models, the flat fee vs percentage comparison is covered in a separate guide.

What does a chargeback app do that you cannot do by hand?

A good chargeback app reads your order, shipping and customer data, builds the evidence packet for you, and reminds you of the deadline. You could do all of that by hand. What a chargeback app changes is speed and consistency, because a tool does not forget a step on the fifth dispute of a busy Friday.

In practice the claimed benefits fall into four groups:

• Speed. The packet is pre-filled, so you review instead of build.
• Consistency. The same fields are filled in every time, which matters when you are tired or the case is unusual.
• Deadline help. Alerts and queues keep a dispute from sitting unseen until it is too late.
• Record keeping. Outcomes are logged, which makes patterns easier to see.

None of those is a guarantee of a win, and you should be wary of any listing that says otherwise. I found vendor statistics on win rates and share of disputes by type in search results. I do not use them here, because I could not verify them and vendors have an interest in the numbers.

What can a chargeback app not do?

It cannot change the bank's decision, fix a policy you never wrote, create proof that does not exist or stop customers from disputing. If the carrier never scanned the parcel, no tool can invent a delivery record. If your store has a fraud problem at checkout, a chargeback app helps you respond to the disputes but does not remove the cause. For that, look at prevention: clear contact details, a billing descriptor that matches your store name or domain, and policies that are easy to find, all of which Shopify lists in its own prevention guidance.

How do you work out the break-even for a chargeback app?

You work it out with two comparisons: time saved against the price, and extra wins against the price. If time saved alone covers the chargeback app, the choice is easy. If it does not, the chargeback app has to win extra disputes to justify itself, and you can work out how many.

Use these terms:

• D is disputes per month.
• M is minutes you spend per dispute by hand.
• S is minutes you save per dispute with the chargeback app.
• H is the hourly value of your time.
• Q is the chargeback app's monthly cost.
• R is the average disputed amount.
• F is the Shopify fee, A$25.

Time saved per month                = D x (S / 60) x H
Time-only break-even (disputes)     = Q / ((S / 60) x H)
Value of one extra win              = R + F
Extra wins needed per month         = (Q - time saved) / (R + F)

The value of one extra win is the order value plus the fee, because Shopify's fee table lists Australia as a country where the A$25 fee is refunded if you win. A win brings back both. If you lose, both stay gone. That is why an extra win is worth more than the sale alone.

Illustration 1: where does time alone cover a flat fee?

Take a flat A$39 a month app. You spend 30 minutes a dispute by hand, the chargeback app cuts that to 10 minutes of review, so S is 20, and your time is worth A$40 an hour. Each dispute then saves A$13.33 of time.

Disputes per month	Time saved	App price	Result on time alone
1	A$13.33	A$39	A$25.67 short
2	A$26.67	A$39	A$12.33 short
3	A$40.00	A$39	A$1.00 ahead
6	A$80.00	A$39	A$41.00 ahead
10	A$133.33	A$39	A$94.33 ahead

The time-only break-even is 39 divided by 13.33, which is 2.9. So three disputes a month is the point where this flat fee is covered by time saved, in this illustration. The A$39 price and the 20 minute saving are assumptions chosen for the sums, not quotes from any chargeback app.

Illustration 2: how many extra wins does a quiet month need?

Now take the same store with one dispute a month and an average disputed amount of A$120. Time saved is A$13.33 against an A$39 price, so the shortfall is A$25.67. One extra win is worth A$145 (A$120 plus the A$25 fee).

Extra wins needed per month are 25.67 divided by 145, which is 0.18. In a one-dispute month, the chargeback app has to turn about 18% of your disputes from losses into wins, roughly 1 in 6, to pay for itself. Nobody can tell you in advance whether it will. That is why the chargeback app vs doing it yourself answer for a very quiet store is usually to keep doing it by hand, or to take a free plan.

Illustration 3: what does each model cost at six disputes a month?

Take six disputes a month at A$120 each. By hand you win 2 of 6. Assume, only for this illustration, that a good app lifts that to 3 of 6. Your time is A$40 an hour. By hand each dispute takes 30 minutes, which is A$20. With a chargeback app it takes 10 minutes, which is A$6.67, so six disputes cost A$40 in time. The percentage app takes its cut on the disputed amount only. Whether a particular vendor also takes a cut of the fee is something to ask.

	By hand	Flat A$39 app, 3 wins	25% app, 3 wins	Flat A$39 app, 2 wins	25% app, 2 wins
Wins out of 6	2	3	3	2	2
Money back (amount plus A$25 per win)	A$290	A$435	A$435	A$290	A$290
App charge	A$0	A$39	A$90	A$39	A$60
Your time cost	A$120	A$40	A$40	A$40	A$40
Net after app and time	A$170	A$356	A$305	A$211	A$190

Read the last two columns first, because they are the cautious case where the chargeback app wins no more than you would have. Even then the flat app comes out A$41 ahead of doing it yourself and the percentage app A$20 ahead, because of time saved. Read the middle columns next: one extra win lifts the gain to A$186 with the flat fee and A$135 with the percentage. These are not forecasts. They show where the money moves.

The pattern in the table is worth remembering. A percentage model takes a cut of every win, including the ones you would have made yourself. It is cheaper than a flat fee when you win little, and more expensive when you win a lot. With A$120 disputes, a 25% cut costs A$30 a win, so two wins in a month cost A$60, which is more than the flat A$39. One win costs A$30, which is less.

How do you run the sums for your own store?

Run them in five steps. Each takes a few minutes with your own numbers.

1. Count your disputes for the last three months and divide by three.
2. Time your next three by-hand disputes with the log above, or estimate honestly.
3. Decide the hourly value of your time and write it down.
4. Get each chargeback app's current price, and ask how the percentage is calculated.
5. Plug the numbers into the formulas and write down the break-even.

When is doing it yourself the better choice?

Doing it yourself is the better choice when disputes are rare, when your records are clean and when your time is cheap relative to the chargeback app's price. If you get one dispute a month and your packet takes 20 minutes, the time you could save is too small to cover most monthly fees.

It also suits cases where the situation is unusual. A dispute that hinges on a long customer history, a custom product or a one-off arrangement needs your judgment, and no template covers it. You know your business better than a tool does.

A few signs the chargeback app vs doing it yourself answer is "yourself":

• You have had fewer than three disputes a month for the last three months.
• Your carrier proof and order records are in one place and take minutes to find.
• You are comfortable with Shopify's dispute screens and always respond with days to spare.
• You do not want to grant a third party access to store data, for any reason.
• Your time is not the limiting factor in your week.

When is a chargeback app the better choice?

A chargeback app is the better choice when disputes are frequent, when each one takes you half an hour or more, or when you keep nearly missing deadlines. At that point the cost of your time and the cost of a missed deadline exceed the cost of the tool.

Some signs the chargeback app vs doing it yourself answer is "a chargeback app":

• You have three or more disputes a month and the number is rising.
• Responding eats into time you need for product, orders or customers.
• You have missed or nearly missed a deadline, since a dispute with no saved evidence goes out with nothing.
• Your records are spread across Shopify, your carrier's site, your inbox and your helpdesk, and you rebuild the picture each time.
• You run several stores and repeat the same routine across all of them.

If you land in the middle, do not decide on feeling. Run the break-even sums and put the answer in your diary for review in three months.

Is a hybrid approach worth considering?

Yes, for many stores. A hybrid means doing the unusual disputes by hand and letting a tool prepare the routine ones, or using a free plan until volume grows. It limits what you pay while keeping control of the cases where your judgment matters most.

A simple hybrid looks like this:

• Use a free plan or a trial while disputes are few, and keep your own packet kit for each.
• Move to a paid plan only when your time log and your dispute count say the sums work.
• Keep handling the odd cases by hand even after you adopt a tool, such as a long customer history or a bespoke order.
• Review the arrangement every quarter, since your volume will change.

The hybrid also protects you from lock-in. If you never lose the habit of building a packet, you can stop paying for a tool without losing the ability to respond.

What are the risks of using a chargeback app?

The risks are access, accuracy and cost creep. A chargeback app reads store data, so you should know which permissions it asks for. It also files on your behalf, so you should know who approves what. And percentage pricing can grow with your sales in ways a flat fee does not.

The questions below apply to any chargeback app. I cover them in more depth in the guides on app safety and how to choose a chargeback app.

Risk	What to ask	Why it matters
Data access	Which permissions does it request, and why does it need each one?	Shopify shows the access a chargeback app has, and you can compare that with what the chargeback app claims to do
Approval	Can you review and approve every filing before it is sent?	A packet sent without your check could contain an error with your name on it
Evidence honesty	Does it only use facts from your records, or can it write things you never provided?	A made-up claim in a dispute can hurt you if the bank checks it
Pricing creep	Is the percentage applied to wins you would have made anyway?	It changes the break-even in the table above
Exit	What happens to your data and open disputes if you stop?	You should be able to leave without losing a deadline
Support	Who answers when a deadline is close and something breaks?	A tool is only as good as the help you get on a bad day

How do you test a chargeback app fairly in two weeks?

Test it on real work, with a timer and a baseline. Before you start, record your by-hand time and your last three months of disputes. Then run a trial on live or recent disputes, record the same numbers with the tool and compare the two sets of figures.

Here is a day-by-day plan you can start today, Wednesday 14 October 2026. It runs for 15 days and ends on Wednesday 28 October.

Day and date	What to do
Wed 14 Oct	Export your last 90 days of disputes and orders. Count disputes and write down each reason and amount.
Thu 15 Oct	Work out your average disputed amount, your disputes per month and your hourly value.
Fri 16 Oct	Time one by-hand dispute from start to finish with the time log, or pull the notes from a recent one.
Mon 19 Oct	Shortlist one or two apps. Write down each price, pricing model, trial terms and data permissions.
Tue 20 Oct	Check the permissions each chargeback app asks for in your Shopify admin before you install anything.
Wed 21 Oct	Start a trial of one app. Run a recent, already-closed dispute through it to see the packet it builds.
Thu 22 Oct	Compare that packet with your own by-hand packet. Note anything missing, anything wrong and the minutes it took.
Fri 23 Oct	Check how the chargeback app handles Australian carriers, since not every tool reads local tracking.
Mon 26 Oct	Run the break-even sums with real minutes, the real price and your dispute count.
Tue 27 Oct	Decide: keep doing it by hand, stay on a free plan, or pay. Write the reason down.
Wed 28 Oct	Set a diary reminder for 28 January 2027 to rerun the numbers.

Do not judge the tool on a single dispute. One win proves nothing, and one loss proves nothing either, because the bank, not the tool, decides. Judge it on the minutes it saves, the quality of the packet and whether you would be comfortable sending it as it stands.

What's different for Australian merchants?

Australian merchants pay a fee of A$25 per chargeback on Shopify Payments, which Shopify's fee table lists as refunded if you win. You also deal with local carriers and local consumer rules. Those details change the chargeback app vs doing it yourself sums more than most guides admit.

Three Australian points matter:

• The fee is in A$, and it comes back on a win. Most guides quote a US$15 fee. Use A$25 in your sums, and remember it is part of the value of every win.
• Local carrier proof is a gap in many tools. I could not verify what proof Sendle, StarTrack or Aramex give, and one seller reports that Australia Post keeps tracking for about 35 days. I could not confirm that figure. Whatever tool you use, check that it can use your carrier's proof, and save it on delivery day.
• Consumer rules apply. WA Consumer Protection says online orders from Australian sellers must meet consumer guarantees, and that a no-refund sign cannot remove those rights. A dispute can sit alongside a consumer-law claim, and a tool does not decide that for you.

Two things I could not verify are worth stating. I could not confirm how GST or BAS applies to a disputed or refunded sale, so the sums here exclude GST. Check the ATO's guidance or ask your accountant. And I could not confirm how Australian public holidays affect due dates, so keep your own deadline two days early.

Common mistakes

1. Comparing the chargeback app's price with nothing. Compare it with your time cost and with your extra wins. If you have not timed a dispute, you do not know what you are comparing.
2. Counting only typing time. The hunt for the order, the carrier page and the customer message is most of the work. Time the whole job.
3. Treating a win rate as a promise. No app controls the bank. Ignore any listing that promises outcomes, and ignore the statistics you cannot trace.
4. Ignoring how a percentage is applied. Ask whether it covers wins you would have made anyway, and whether it applies to the fee as well as the amount.
5. Installing before checking permissions. Look at what the chargeback app can read before you accept it, and remove anything it does not need.
6. Letting a tool file without your review. A packet with an error is worse than a short one you wrote yourself. Make sure you approve each filing.
7. Forgetting the deadline is still yours. Shopify submits what you have saved on the due date. A chargeback app can remind you, but it does not move the date.
8. Never rerunning the sums. Volume changes. A tool that made sense at two disputes a month may not at six, and the reverse is true as well.

Frequently asked questions

Is a chargeback app worth it for a small Shopify store?

Often not, if you have one or two disputes a month. In the illustration here, a flat A$39 app is covered by time saved only from about three disputes a month. Below that, the app has to win extra disputes to pay for itself. Time your own disputes and run the break-even sums.

How long does it take to respond to a chargeback by hand?

One third-party source puts it at 20 to 45 minutes per dispute. I could not verify that for Shopify stores, so use it as a range to test. Time your next three disputes from opening the case to saving the evidence, including the hunt for the order and carrier proof.

Will a chargeback app win more of my disputes?

I cannot promise that and I could not verify any vendor win rate. Shopify says it does not decide outcomes and strong evidence does not guarantee a win, because the bank decides. A fair test looks at minutes saved and packet quality first, and treats any extra wins as a bonus.

Is a percentage fee or a flat monthly fee cheaper?

It depends on how many disputes you win. A percentage costs nothing in a month with no wins, but takes a cut of every win. In the six-dispute illustration with A$120 orders, a 25% cut costs A$30 a win, so two wins cost A$60, more than a flat A$39.

Does Shopify refund the A$25 chargeback fee if I win?

Shopify's fee table lists Australia as a country where the A$25 fee is refunded if you win, and the disputed amount returns too. If you lose, both stay gone. That is why each extra win in the sums is worth the order value plus A$25.

What happens if I miss the deadline with or without an app?

Shopify submits the evidence you have saved on the due date, and a dispute whose deadline has passed cannot be changed. If you saved nothing, nothing goes out. An app can send reminders, but the date is still yours to meet, so keep an internal cutoff two days early.

Can I switch between doing it yourself and using an app?

Yes, and a hybrid often makes sense. Use a free plan or a trial while volume is low, keep your own packet kit, and move to a paid plan only when your time log and dispute count support it. Before you commit, ask what happens to your data and open disputes if you leave.

What should I check before installing a chargeback app?

Check which permissions it requests and why, whether you approve every filing before it is sent, whether it only uses facts from your records, how its percentage is applied, how it handles Australian carrier proof, and what happens when you stop. Ask before you install, not after.

How often should I rerun the app versus DIY sums?

Every quarter is enough for most stores, or sooner if your dispute count jumps. Update your minutes per dispute, the hourly value of your time, your average disputed amount and the app's current price. A tool that made sense at two disputes a month may not at six, and the reverse is also true.
