The short version

  • Each has a real cost: Feedzai pricing is per transaction with an annual minimum, so a bank with seasonal or growing volume commits to a floor it may not use and pays overage above the band.; Klarna merchant fees for the short-term products run around 5.99% plus a fixed fee in the United States, roughly double a standard card rate, so unless Klarna measurably lifts average order value or conversion it is a straight margin loss.
  • They diverge on capability: Feedzai covers Real-time scoring, Klarna covers Pay in 4.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Feedzai

  • Pricing is per transaction with an annual minimum, so a bank with seasonal or growing volume commits to a floor it may not use and pays overage above the band.
  • It sits in the authorisation path, which makes every upgrade a change-controlled event with rollback plans, and the operational burden falls on the bank rather than the vendor.
  • Out of the box models need months of the customer own labelled fraud history before they beat the rules they replace, so the value case starts late.
  • AML and fraud are licensed as separate modules, so institutions expecting one platform fee find the transaction monitoring capability is a second line item.
  • The buyer profile is large institutions, so smaller banks and fintechs face minimums that make per-transaction economics unattractive below significant scale.

Klarna

  • Merchant fees for the short-term products run around 5.99% plus a fixed fee in the United States, roughly double a standard card rate, so unless Klarna measurably lifts average order value or conversion it is a straight margin loss.
  • Rates are negotiated and unpublished, which means small merchants pay the standard rate while large ones negotiate down, and you cannot benchmark what you are being charged without going to market.
  • Returns and partial refunds are handled through Klarna's systems rather than your payment processor, so your finance team reconciles a second settlement flow and customer service handles a second dispute process.
  • Buy now pay later is being brought under consumer credit regulation in the UK, the EU and Australia, which is already changing affordability checks and disclosures; the checkout experience that converts today may be legally required to add friction.
  • Klarna owns the post-purchase relationship, sending payment reminders and marketing in its own name, so a shopper who has a poor collections experience associates it with your brand while you have no control over the messaging.

Answered from the vendors’ own pages

Feedzai: Can Feedzai run on-premises?

Yes. On-premises and private cloud deployments are supported, which is why it appears in markets where transaction data cannot legally leave the country.

Klarna: What does Klarna cost a merchant?

Klarna does not publish a rate card. In the United States most merchants pay around 5.99% plus $0.30 for short-term products, with longer-term financing nearer 3.29% plus $0.30, and large merchants negotiate lower.

Feedzai: Does it cover AML as well as fraud?

It does, but transaction monitoring is a separately licensed module. Assume two line items if you want both.

Klarna: Does the merchant carry the credit risk?

No. Klarna pays the merchant the full amount less fees and takes the risk of the shopper not paying.

Feedzai: How fast are decisions?

Designed for the authorisation window, typically tens of milliseconds. This is the constraint that rules out batch scoring architectures.

Klarna: Can I use Klarna alongside my existing processor?

Yes. It is normally added as an additional payment method through Shopify, Adyen, Stripe or a direct integration rather than replacing your card acquirer.

Klarna: Is Klarna still independent?

Yes. It listed on the New York Stock Exchange in September 2025 and holds a Swedish banking licence.
