Nobody wins when a chargeback happens. But clear communication and the right evidence can prevent most of them—and resolve the rest.

Written by Tyler Storch, Manager, Customer Success Operations

A chargeback happens when a customer disputes a charge directly with their bank instead of reaching out to the league (the merchant). The payment gets reversed, and the league has to submit evidence proving its customer agreed to a financial policy—or the money is gone.

Most of the time, nobody is the villain. The customer doesn’t remember agreeing to a no-refund policy or even for what they’ve paid. The league can’t prove they made it clear. Both sides lose.

The good news is that most disputes are preventable. And when they do happen, the right approach, the right language, the right documents, and the right framing can significantly improve your chances of winning.

Here’s what the data shows.

Better communication prevents disputes in the first place

The best defense against wrongful chargebacks isn’t better evidence after the fact. It’s clearer communication before the charge ever happens.

A parent forgets they signed up for a recurring membership. They don’t remember agreeing to a no-refund policy buried in a terms page. They’re not acting in bad faith, they’re frustrated and reaching for the dispute button because it’s easy.

When you communicate clearly upfront, two things happen:

1. Fewer parents file disputes in the first place because they understand what they’ve agreed to.
2. When disputes do happen, you already have documentation proving you communicated clearly.

This means building registration flows that surface cancellation terms prominently, sending confirmation emails that reiterate refund policies, and using electronic signatures that require parents to actively acknowledge what they’re agreeing to.

How are credit card disputes actually decided?

When a parent files a chargeback and a merchant challenges it, a bank reviewer looks at the submitted evidence and makes a call. They don’t have much time, usually just a few minutes per case.

They’re not asking whether your program was worth the money. They’re not asking whether the child showed up to practice. They’re asking: Did the parent know the terms before they paid?

Most dispute responses answer the wrong question.

The overwhelming majority of dispute submissions say some version of “our program is non-refundable.” But that tells the reviewer what your policy is, not whether the parent knew about it before paying. Those are two very different things.

Responses focused on proving informed agreement win at more than twice the rate of responses that simply assert a non-refundable policy. The framing is the difference between winning and losing.

Visa is harder to win than Mastercard

Not all disputes are decided the same way, and the card network matters more than most LeagueApps partners realize.

Partners win Mastercard disputes at nearly twice the rate of Visa disputes. For “Subscription Canceled” chargebacks, one of the fastest-growing categories, that gap widens further. Partners win on Mastercard at more than three times the rate they win on Visa for that category.

Why the difference? Visa reviewers require more explicit proof that the parent accepted terms before paying. Evidence that satisfies Mastercard’s standard consistently falls short of Visa’s, not because the evidence is weak, but because Visa holds consent to a higher bar.

If you’re seeing a pattern of Visa losses, the issue likely isn’t your evidence, it’s how you’re presenting it. Visa responses need to be more explicit about the moment of agreement: when the parent saw the terms, what they acknowledged, and how that was captured. Partners that adapt their language to Visa’s standard see meaningful improvement.

The three files that matter most

After analyzing thousands of disputes over two years, we’ve come to a conclusion that not all evidence carries equal weight. Three document types appear in winning submissions at dramatically higher rates than in losing ones:

• Customer communications (emails, messages, confirmations from parents) appear in winning submissions at roughly 60% higher rate than in losing ones.
• Registration flow screenshots showing where terms were displayed appear at a roughly 60% higher rate in wins than losses.
• Signed refund policies appear at nearly a 50% higher rate in wins than losses.

When none of these three are present, win rates fall to less than half of what they are when even one is included. Submitting all three together produces win rates nearly three times higher than submissions with none of them.

The pattern is consistent across every dispute category: The partners that win are the ones who built their evidence trail at registration, not the ones trying to reconstruct it afterward.

How many files should you submit?

Going from zero files submitted to just one nearly triples your win rate. The sweet spot is 3 to 5 files. At 6 or more, win rates start to decline as reviewers lose focus on what matters.

Quality and relevance beat volume every time. Winners submit roughly half a file more than losers on average, but the difference is in what those files are, not how many there are.

How long should your response be?

Leaving the description field empty is essentially an automatic loss. Submissions with empty descriptions win at a near-zero rate, making them the worst-performing group in the entire dataset by a wide margin.

The sweet spot is 750 to 1,500 characters. Submissions in that range consistently outperform both shorter and longer responses. Going beyond 2,000 characters and win rates fall back off.

We also discovered winning cases actually had shorter “additional information notes” than losing ones (on average). Conciseness signals confidence and clarity. Lengthy responses that circle back on the same points or include emotional context tend to hurt more than they help.

The “why should you win” field is critical

This is one of the most overlooked levers in the entire dispute response. Leaving it blank produces nearly the same near-zero win rate as submitting no evidence at all.

The field selection matters as much as anything else you submit. “Cardholder withdrew the dispute” produces win rates nearly twice as high as the standard “transaction was non-refundable” selection, when that situation applies. If a parent contacted their bank to withdraw and you have documentation of it, use it. That framing alone changes the outcome.

Evidence strength by dispute type

The gap between strong and weak evidence is not consistent across dispute categories. It is most dramatic for duplicate disputes, where strong evidence produces win rates more than five times higher than weak evidence. For Subscription Canceled and Fraudulent disputes, strong evidence roughly doubles your win rate.

The harder a dispute category looks on the surface, the more your evidence quality determines the outcome. A well-documented Duplicate dispute is actually very winnable. An undocumented one almost never is.

6 Strategies that boost win rates

1. Get explicit authorization at registration. Don’t bury terms in fine print. Surface cancellation and refund policies where parents must actively acknowledge them, ideally with an electronic signature. This is the single most important step, both for preventing disputes and for winning them.
2. Save everything. Screenshots of the registration flow. Confirmation emails. Any parent communication about refunds or cancellations. Build your evidence trail before you ever need it, because you can’t reconstruct it after the fact.
3. Frame responses around agreement, not policy. When responding to a dispute, emphasize that the parent understood and accepted the terms before paying, not just that your program is non-refundable. This framing shift more than doubles your odds of winning.
4. Use specific, precise language. Certain phrases are strongly associated with winning. “Cancellation rights,” “electronically signed,” “agreed to,” “seasonal,” and “full season” all significantly outperform generic policy language. Word choice matters to reviewers. See the language section below for what to use and what to avoid.
5. Submit 3 to 5 targeted documents, not everything you have. Give reviewers exactly what they need: a signed refund policy, a registration flow screenshot showing where terms appeared, and relevant parent communications. Going beyond 5 files produces diminishing returns. Relevance beats volume.
6. Stay within the 750 to 1,500 character range for your narrative. Too short and you’re not telling the full story. Too long and reviewers lose the thread. Keep it tight, focused, and free of emotional appeals. Every sentence should be doing work.

Do’s and don’ts: Language that wins and language that doesn’t

The words you use have a measurable impact on outcomes. Here is what the data shows in relative terms:

• “Cancellation rights” wins at more than twice the rate of “non-refundable” alone
• “Electronically signed” and “e-sign” win at roughly 40 to 80% higher rate than submissions without explicit signature language
• “Agreed to,” “seasonal,” and “full season” all significantly outperform passive policy descriptions
• “Withdrawn” or “withdrew” are among the strongest phrases in the dataset when applicable, winning at roughly twice the baseline rate
• “Non-refundable” alone is the weakest framing when used without consent language—useful context but not a substitute for proving agreement

Phrases that consistently underperform:

• “Does not apply” leads to a lower win rate, as it leans emotional and dismissive of the customer rather than focusing on disproving the dispute reason in a measured way.
• “Participated” and “Commitment” both fall well below average, likely because they shift the reviewer’s attention to whether the child attended rather than whether the parent agreed.

Emotional appeals, descriptions of the child’s experience, and explanations of why the program is valuable all fall into the same trap. Reviewers are evaluating consent, not the quality of your program.
