Klarna On‑Site Messaging

We’re a UK guitar parts retailer and have offered Klarna for several years. We’ve now removed it from our store.

A customer claimed one item was missing from a three-item order and opened a Klarna dispute. We responded with tracked delivery, Royal Mail’s proof of delivery, and CCTV of the order being packed. The customer’s own emails contradicted each other on when and how he received the parcel.

Klarna’s process only lets you submit evidence once. When we contacted Merchant Support to add more, we were told the dispute was “locked for review” and that Klarna would ask if it needed anything else. It never did. It found in the customer’s favour and refunded him on technical grounds about the format of the proof of delivery.

Shortly afterwards, the customer messaged us to boast that he had won the dispute and had all three items all along. We sent this straight to Klarna. Their answer: the decision “will not be revised”, and we should chase the customer ourselves. We asked to speak to the dispute team or a manager and were told there is no phone option and no callback.

So the merchant gets one chance to submit evidence and can’t add anything once it’s in. Proof that the claim was false is ignored, and there’s no one to speak to. That isn’t merchant protection.

We’re now pursuing the customer through the courts at our own expense. If you’re a small retailer considering Klarna, read their Merchant Protection terms very carefully, and think about whether you’d be happy losing every borderline dispute.

I don't leave negative reviews often, but after this experience I think other Shopify merchants deserve the warning.

I've spent weeks trying to get Klarna connected to my store. Shopify support confirmed my Merchant ID is valid and active on their end, so the problem sits with Klarna's own integration. The app fails to connect with an error every time.

Every time I've contacted Klarna support, the response has been automated: a bot sending links to generic setup documentation. None of it addresses a connection error with an already-confirmed Merchant ID, because it's all written for someone setting up the app for the first time, not someone whose setup is already failing. I've explained this repeatedly and gotten the same doc links back each time. No human has actually looked at the error.

So now I'm stuck in a loop: Shopify says the integration is Klarna's to fix, and Klarna's support system won't route me to a person who can fix it. Weeks in, still unresolved, still no reply from an actual human being.

If you're considering Klarna for your store, know that the moment something doesn't work as expected, you're on your own with a chatbot. I wouldn't build a checkout dependency on a payment provider whose support layer can't handle a problem that isn't in their FAQ.

As a PM in my past life, I have a theory that this app was intentionally designed to fail. It doesn't make sense.
