Klarna vs Affirm vs Afterpay Chargebacks: A Merchant’s Guide to BNPL Disputes
Three providers, three rulebooks, one evidence problem. Here is how Klarna, Affirm, and Afterpay each handle disputes, and the record that wins all three.
Klarna, Affirm, and Afterpay each route chargebacks differently. Affirm absorbs most disputes internally. Klarna pushes product and service disputes to the merchant with a roughly $15 fee. Afterpay handles payment disputes itself but forwards product disputes to you. The win condition is the same across all three: a captured, time-stamped record of what the customer saw and agreed to at checkout.
Picture this: a customer checks out with Klarna for a $480 order. Six weeks later, after two installments, they file a dispute claiming the product never arrived. Klarna emails you with a five-day evidence window. You send the carrier scan. Klarna decides for the customer. The chargeback hits, plus a $15 fee. The next week, a different customer disputes a $620 Afterpay order, and a third disputes an Affirm purchase you never even hear about until it shows up on a statement. Three providers, three outcomes, three different reasons you lost.
Why BNPL chargebacks are not card chargebacks
Most merchants treat buy now, pay later like a Visa or Mastercard transaction. The mechanics are nothing alike. With a card, the dispute travels through the issuer, the network rulebook (Visa, Mastercard, Amex, Discover), and lands on your acquirer with a reason code and a representment window. With BNPL, the dispute is governed by your merchant agreement with the BNPL provider. Klarna, Affirm, and Afterpay each wrote their own.
That matters because friendly fraud rates run higher on BNPL than on cards. The reason is structural. BNPL lowers the friction on bigger purchases, which pushes average order value up, which is exactly the bracket where buyer’s remorse spikes into a dispute. Industry estimates put friendly fraud at roughly 36% of all ecommerce fraud cases and 61% of chargeback disputes. On BNPL, the share trends higher because the buyer feels the payments arrive after they have already changed their mind about the purchase.
The other structural problem is that BNPL providers, unlike card networks, often do not surface the dispute to the merchant at all until after a decision is made. So the merchant cannot fight a dispute they never knew about. And when they can fight one, the evidence rulebook is the BNPL’s, not the network’s, and the timeline is shorter.
“BNPL chargebacks are not one process. They are three different rulebooks happening in parallel.”
Affirm, Klarna, and Afterpay: how each handles disputes
Here is the side-by-side. Each card lays out how the provider routes a chargeback, who responds to the customer, what the merchant has to produce, and the fee posture. The differences are the entire reason a unified evidence record matters.
- Routing
- Affirm fights most disputes itself using its own transaction data. Merchants are looped in less often than with the other two providers.
- What you respond to
- Documentation requests when Affirm decides it cannot resolve internally. Response window is short.
- Risk for the merchant
- Your strongest checkout-side evidence may never enter the case. You learn the outcome on a statement.
- Routing
- Payment-related disputes (unauthorized, processed wrong) stay with Klarna. Product or service disputes (item not received, not as described, refund not given) are routed to the merchant.
- What you respond to
- Direct merchant response in Klarna’s portal, on Klarna’s clock, in Klarna’s required format.
- Risk for the merchant
- You take both the chargeback loss and a per-dispute fee.
- Routing
- Payment disputes are absorbed internally. Product and service disputes are forwarded to the merchant for response.
- What you respond to
- Submission through Afterpay’s merchant portal with their own evidence template and timeline.
- Risk for the merchant
- Same liability profile as Klarna for the disputes that get pushed to you, on a different SLA and a different portal.
Three providers. Three portals. Three definitions of what counts as proof. A single merchant who accepts all three, which is now the norm, is operating three dispute pipelines whether they know it or not.
The evidence gap that costs merchants BNPL disputes
The reason BNPL disputes go sideways is not that merchants are sending bad evidence. It is that they are sending the only evidence they have, and the only evidence they have is the carrier scan and a record of the order in their backend. None of that proves what the customer saw, agreed to, or did at checkout. Here is where the chain breaks.
A BNPL Dispute, Step By Step
Customer checks out with Klarna, Affirm, or Afterpay
Order summary renders. Terms and shipping address are shown. Customer clicks the BNPL CTA and authenticates with the provider.
Merchant captures the order in their backend
Order ID, total, shipping address, line items, BNPL transaction ID. Standard ecommerce data. Not a record of what was rendered on the customer’s screen.
Customer disputes the charge weeks later
Reason: never received, not as described, did not authorize, or “I did not order this.” The dispute is filed inside the BNPL provider’s app.
The evidence ask arrives, and this is where merchants lose
The provider asks for proof of what the customer saw, agreed to, and was told about returns. The merchant has order data, not session evidence. The dispute is decided on what the BNPL provider has, which is the customer’s statement.
Outcome posts to the merchant’s account
Loss, plus fee where applicable. The next dispute on a different BNPL goes through a different portal, and the cycle repeats.
The gap at step four is the same gap on every chargeback the merchant loses, BNPL or card. The defense is missing the rendered page, the timestamped agreement, and the captured customer interaction. Our piece on what actually wins chargeback disputes walks through the same gap on the card side.
One evidence record that wins all three
The good news is that all three BNPL providers will accept the same kind of evidence. They have to, because the underlying questions are universal: did this customer place this order, see these terms, confirm this address, and acknowledge this charge? You do not need three evidence pipelines. You need one canonical record per checkout, formatted into each provider’s response template when a dispute opens.
The Unified BNPL Evidence Record
Four layers, one record, three provider portals
Rendered page evidence at checkout
A captured reproduction of the order summary the customer saw, including price, line items, shipping address, return policy disclosure, and the BNPL plan terms. This is what answers the “they never agreed to that” claim.
Timestamped affirmative consent
A tamper-evident timestamp on the click that submitted the order, tied to the version of terms shown at that moment. This is what answers “I never authorized that” on payment-reason disputes.
Session-level capture of the actual interaction
An end-to-end record showing the customer was the one completing the purchase, the order summary was visible, and they progressed through it. Session-level capture at checkout is what makes the rest of the stack defensible.
Post-purchase confirmation receipt
A delivered email or in-app confirmation showing the customer received the order acknowledgment. The email receipt evidence is the close on item-not-received reason codes.
One record. Reformatted, not rebuilt, when the dispute lands in Klarna’s portal, Affirm’s documentation request, or Afterpay’s response form. This is what Evidora was built for. The product exists to capture the rendered checkout, the timestamped click, and the post-purchase confirmation as court-ready digital evidence, then produce a reproduction on demand when a chargeback or inquiry arrives. One line of code. Retain what matters, expire what does not.
For broader context, the chargeback environment is also tightening on the card side. Visa lowered the VAMP threshold on April 1, 2026, and friendly-fraud disputes that look a lot like the BNPL pattern are climbing across the board. External documentation on the rule frameworks is also worth keeping handy: the Mastercard chargeback guide covers the network-side rules that apply when a BNPL provider funds with a card, and the Federal Reserve’s Regulation E reference covers non-card disputes that overlap with several BNPL flows.
Frequently asked questions
Does Klarna charge merchants a chargeback fee?
Yes. Klarna typically charges merchants around $15 per chargeback when a dispute is filed and routed to the merchant for response. The fee applies whether the merchant wins or loses the case, which is part of why product and service disputes need a clean evidence packet from the start.
Does Affirm pull merchants into disputes the same way Klarna does?
Usually no. Affirm absorbs most disputes internally and resolves them with its own transaction data. Merchants are looped in less often, but that also means the merchant’s strongest checkout evidence may never enter the record. When Affirm requests documentation, the response window is short.
How does Afterpay handle chargebacks for merchants?
Afterpay manages payment-related chargebacks itself and forwards product-related and service-related disputes to the merchant for response. The merchant has to submit evidence in Afterpay’s required format on Afterpay’s timeline, similar to Klarna though with different SLAs and a separate portal.
Is BNPL friendly fraud higher than card friendly fraud?
Yes. BNPL lowers the friction on larger purchases, which increases buyer’s remorse rates. Friendly fraud disputes tend to spike on transactions where the customer feels the price is high relative to the product, and BNPL is concentrated in that bracket.
What evidence wins a BNPL dispute?
The same checkout-side evidence that wins a card dispute. The rendered order summary the customer saw, the timestamped click on the agreement, the captured shipping address, the post-purchase confirmation, and a session record showing the customer was the one completing the purchase. Each BNPL provider accepts this in their dispute response template.
Do I need a separate evidence pipeline for each BNPL provider?
No. The dispute portals are different, but the underlying evidence is the same. One canonical evidence record per checkout, formatted per provider when a dispute opens, is the standard approach. Three pipelines is the expensive way to do it.
Are BNPL chargebacks subject to the same Visa or Mastercard rules?
Partially. When a BNPL provider funds a transaction with a card on its own account, card-network rules apply between the BNPL and its issuer. The merchant’s contract is with the BNPL provider, not the network, so the dispute rules the merchant has to follow are set by Klarna, Affirm, or Afterpay’s merchant agreement.
