A chargeback is the most expensive way to lose an argument with a customer: you lose the goods, the money, usually a fee on top, and every case counts toward a ratio that can eventually threaten your payment account. Yet most merchants treat disputes as random weather. They aren’t. The majority are predictable, and a large share are preventable.
Know the dispute routes
- PayPal buyer protection. Two claim types matter: item not received and significantly not as described. The customer reports the problem within 180 days of payment, and you have ten days to respond. If you can’t agree, PayPal decides on the evidence both sides upload. When a buyer files a claim, PayPal charges you a dispute fee, currently €14 per case for EUR transactions according to PayPal Germany’s fee page. The standard fee is waived, among other cases, when PayPal decides in your favor, when you meet all seller protection requirements, or when you settle the dispute directly with the buyer.
- Card chargebacks. The customer calls their bank, the bank pulls the money back through the card network. Works even underneath PayPal or Klarna. A card-funded PayPal payment can come back as a chargeback after you’ve already won the PayPal case. Your payment provider sets the fee. PayPal Germany, for example, currently charges €16 per chargeback on plain card payments that don’t run through a PayPal account or guest checkout, whatever the outcome.
- BNPL disputes (Klarna & co.). When a customer disputes with Klarna, Klarna puts their invoice on hold: they don’t have to pay while the case is open. You get up to 14 days for the first request and seven for each follow-up. Miss one and Klarna resolves the dispute in the customer’s favor.
- SEPA direct debit returns. With a SEPA direct debit, the customer gets the money back through their bank, with no reason given and no review. There is no evidence process; you claim the purchase price from the customer directly.
The shared logic: whoever documents better, wins. And: every dispute costs you time and counts toward your ratio, and most cost a fee. The thresholds small shops hit first are the payment providers’, not the card networks’. At PayPal, the high-volume dispute fee applies once your dispute ratio over the last three calendar months is at least 1.5% and you had more than 100 sales. From then on you pay even for cases decided in your favor. The card network programs start far higher: Visa has flagged EU merchants since 1 April 2026 at a 1.5% ratio with at least 1,500 fraud and dispute cases a month, Mastercard at 1.5% with at least 100 chargebacks a month.
Deadlines at a glance
| Case type | Customer’s deadline | Your deadline | What you submit |
|---|---|---|---|
| PayPal buyer protection | 180 days from payment | 10 days from when the dispute opens, then whatever deadlines PayPal sets | Tracking number showing “delivered” to the address in the transaction details; for “significantly not as described”, item description and photos |
| Card chargeback | at Visa, 120 days from processing or from (expected) delivery for the most common reasons | set by your payment provider, shown on the case in your dashboard | Proof of delivery, communication history, order data, terms accepted at checkout |
| Klarna dispute | 180 days from capture | 14 days for the first request (7 for “unauthorized”), 7 for each follow-up | Tracking, return receipt or refund proof, communication history |
| SEPA direct debit return | 8 weeks without a reason, 13 months for an unauthorized debit (German law: §§ 675x, 676b BGB) | no process | nothing; you claim the amount from the customer directly, with invoice and proof of delivery |
Why chargebacks actually happen
Genuine stolen-card fraud is the minority. Industry analyses consistently attribute the bulk to what’s called friendly fraud, and most of it decodes as ordinary situations that escalated:
- “Where is my order?” with no answer. The customer wrote, waited, wrote again, then asked their bank instead. A dispute is the support ticket you didn’t answer in time.
- The refund felt too slow or too hard. If your returns process is opaque, the bank’s one-click process wins.
- Unrecognized statement descriptor. The card statement says a company name that isn’t your shop name → “I don’t know this charge.”
- Family purchases. The classic “my kid ordered this.”
- Actual fraud. A real but small remainder.
Note that 1–3 are process problems on the merchant side. The good news: that makes them fixable.
Winning the cases worth fighting
When a dispute lands, you’re in an evidence process with deadlines (at PayPal, ten days from when the dispute opens; a missed deadline usually means an automatic loss). Your evidence pack, assembled per case:
- Tracking with delivery confirmation to the address from the payment system. For PayPal seller protection this is a hard condition: ship to the delivery address in the transaction details, with a verifiable tracking number and “delivered” status. If the parcel is redirected to another address, protection doesn’t apply, and PayPal advises against shipping with a carrier the buyer chose.
- The full communication history: timestamps showing you responded, offered solutions, and the customer’s own statements (“arrived, but I don’t like it” kills an item not received claim).
- Order metadata: device, login, prior orders by the same customer.
- Your policy texts as accepted at checkout.
One catch: PayPal seller protection covers item not received and unauthorized payments, but not significantly not as described. Against that claim type, the only defense is a listing that states size, material and condition exactly as the item arrives.
Then do the math before fighting: item value versus fee plus your time plus ratio impact. Below roughly €25–40, a proactive refund is usually the cheaper outcome even when you’d win, with one exception: documented repeat abusers, where folding trains the behavior.
PayPal’s decision isn’t the last word (in Germany)
Losing a buyer protection case doesn’t erase your claim to the purchase price. Germany’s Federal Court of Justice ruled in 2017 (VIII ZR 83/16 and VIII ZR 213/16) that when your PayPal account is debited after a successful buyer protection claim, the purchase price claim revives, and you can pursue it in court. That only pays off for larger amounts with solid evidence, but then it is a real option.
Preventing them: the higher-leverage half
- Answer fast, especially shipping questions. The single biggest lever. A customer who gets a real tracking answer in minutes has no reason to involve a bank (how to automate exactly that).
- Proactive delay notices. The “item not received” dispute is usually a stuck parcel plus silence. Catch the stuck parcel first (the lost-parcel process).
- Make refunds boring. A clean self-service return path with refund-on-first-scan beats the bank’s process on speed, and a refund you execute is a dispute that never existed (the legal baseline).
- Fix your descriptor. Statement text = shop name customers recognize. Two minutes in your PSP dashboard, measurable dispute reduction.
- Track disputes per customer and per SKU. Repeat disputers get signature shipping or prepayment; a SKU with a dispute cluster has a listing problem, not a customer problem.
The operational angle
Everything above is casework: pull the tracking, assemble the communication log, check the address match, apply the value rule, either refund or file the evidence pack, inside a deadline. It’s mechanical, deadline-driven and expensive to do by hand, which is why it’s usually done late or not at all. The bigger lever sits earlier: most disputes never happen when the original question gets a real answer in minutes. Sondercase answers shipping questions with the order’s live tracking, fully automatically if you want, and prepares refunds and returns completely so you release them with one click. If a dispute comes anyway, the order, tracking and timestamped history are already in one place.
