Walley is a Nordic-focused invoice and installment payment method operated by Sweden's Collector Bank group. In Finland, where the habit of receiving goods and paying by invoice afterward remains a consumption pattern, Walley offers B2C deferred invoicing and installment options, with product design built around Nordic retail payment conventions as its strength. Unlike the global brand Klarna, its Nordic-focused positioning is what sets it apart.

It's worth considering for higher-ticket product categories with installment demand—electronics, furniture, sporting goods—and for retail merchants targeting all four Nordic countries together. If global coverage is the priority, compare terms against Klarna.

When the shopper selects Walley at checkout, a real-time credit check is run and invoice (deferred payment) or installment terms are presented; once approved, Walley advances the merchant's funds and then bills and collects from the consumer. The risk of consumer non-payment after approval is, in principle, borne by Walley. The merchant's share of funds is received by Hecto Financial in euros (EUR), converted, and settled in the contracted currency—USD, KRW, or JPY.

Integrating through Hecto Financial lets a merchant based in Korea consider offering invoice and installment options to Finnish customers without contracting directly with Walley. Given the deferred-payment nature of the method, there's a review policy based on product category and average order value, so confirmation before contracting is needed.

• Business registration country

  Confirm whether a contract is possible on a Korea-based business basis

• Sales channels

  Integration method and priority differ depending on your mix of online channels—own site, marketplaces, mobile apps, etc.

• Product categories

  Check in advance whether your products fall under restricted categories per the Walley operator's merchant policy

• EU regulatory compliance

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

The merchant's share of Walley transactions is received by Hecto Financial in euros (EUR) and, after conversion, settled in whichever currency—USD, KRW, or JPY—was selected under contract. Given the deferred-invoice nature, the amount billed to the consumer is adjusted on returns or partial returns, so if your product category sees frequent 14-day withdrawal claims from Finnish consumers, confirm the return-to-invoice adjustment integration at the contracting stage.
