Portuguese e-commerce is dominated by instant-payment methods such as reference-number payment and mobile app approval, but BNPL usage is also growing along with rising demand for installment and deferred payment across Southern Europe. Klarna, Europe's largest BNPL provider and a licensed bank, gives consumers a pay-later or installment repayment option after a review, while paying merchants upfront — a structure where Klarna, not the merchant, bears the credit risk.

It is especially effective for sellers of fashion, electronics, furniture, and sporting goods, where a high average order value makes the burden at checkout more likely to cause drop-off, and it can also be expected to raise cart value. The standard setup is to offer local methods to customers who prefer to pay instantly, and present Klarna to customers who want to spread out their spending.

When a consumer selects Klarna at the payment screen, a real-time credit review is performed, and once approved, the consumer repays on a pay-later or installment schedule while Klarna pays the merchant upfront. In other words, it is a three-step structure of "review approval → upfront payment → consumer installment/deferred repayment," and the identity verification step in the review process also handles the PSD2 Strong Customer Authentication (SCA) requirement. In principle, the risk of delayed repayment is borne by Klarna.

Through Hecto Financial, a domestic corporation can consider offering BNPL options for Portugal without a separate merchant contract with Klarna. Industry restrictions (digital goods, high-risk categories, etc.) and actual terms (settlement cycle, fees, currency options) need to be confirmed through consultation.

• Business registration country

  Confirm whether a contract is possible based on a domestic business registration

• Sales channels

  The integration method and priority vary depending on your online sales channel mix, such as owned store, marketplace, or mobile app

• Product categories

  Advance confirmation is needed on whether your products fall under restricted categories per Klarna's merchant policy

• EU regulatory compliance

  Confirmation is needed on compliance with EU payment regulations such as PSD2 and SEPA (see official sources below)

The basis for merchant settlement is Klarna's upfront payment, not the consumer completing repayment. Hecto Financial collects the upfront-paid euro (EUR) amount, converts it, and pays the domestic merchant in whichever currency — USD, KRW, or JPY — was set in the contract. For fashion businesses with frequent returns, verifying in advance how Klarna's repayment schedule and the merchant's refund are linked and canceled when a consumer exercises the 14-day right of withdrawal can reduce disputes over settlement deductions.
