Spanish e-commerce is the largest in Southern Europe, with card as the default payment method and the bank-backed joint service Bizum rapidly expanding its footprint. In this kind of market, Klarna offers not only immediate payment (Pay Now) but also pay-later invoicing (Pay Later) and installment payment under a single brand, capturing customers who would otherwise delay their purchase due to card limits or the burden of paying immediately.

For categories with high average order values and frequent returns, such as fashion, beauty, and electronics, or for D2C brands where first-purchase conversion matters, Klarna's pay-later option can serve as a conversion booster. Even within the same BNPL category, the model differs from France's Oney (3x/4x card installments) and Italy's Scalapay (3-installment), so design your mix based on your target order value and customer base.

When a consumer selects Klarna at checkout, Klarna runs a real-time credit check and presents pay-later or installment terms, and once approved, the merchant payout is confirmed with Klarna bearing the amount. The risk of consumer non-payment rests with Klarna in principle, and Hecto Financial collects this payout in euros (EUR), converts it, and settles it with the Korean merchant.

Integrating through Hecto Financial lets a Korean corporation consider adopting Klarna without a local Spanish contract. Because BNPL approval policies are more segmented by industry and order value than card, confirming actual eligibility and terms (settlement cycle, fees, currency options) with the sales team before contracting is necessary.

• Business registration country

  Confirm contract eligibility based on domestic business registration

• Sales channels

  The integration approach and priority differ depending on your online sales channel mix, such as your own site, open marketplaces, and mobile apps

• Product categories

  Check in advance whether your category falls under restricted industries per Klarna's merchant policy

• EU regulatory compliance

  Confirm compliance with EU payment regulations such as PSD2 and SEPA (see official sources below)

Even though the consumer pays in installments or later, the merchant payout is confirmed as of the approval point, and Hecto Financial collects it in euros (EUR) and settles it after conversion in whichever currency was contracted — USD, KRW, or JPY. Categories with frequent returns and partial refunds should confirm Klarna's refund reflection process and settlement deduction method before contracting, and canceling the remaining installment schedule when an EU customer exercises the 14-day right of withdrawal for distance sales should also be checked.
