Denmark has not adopted the euro and keeps its own currency, DKK, but on the payments infrastructure side it participates in SEPA (the Single Euro Payments Area). Day-to-day low-value payments are dominated by Dankort and MobilePay, so SEPA Direct Debit's place is in areas that need recurring billing, such as subscriptions, memberships, and B2B invoicing, specifically for customers who hold a euro account. Keep in mind that SDD sits in a complementary position, since domestic direct debit in Denmark runs on its own separate local scheme as the standard.

This makes it worth considering first for Korean merchants with recurring billing, such as SaaS and content subscriptions or regular deliveries, where reducing payment churn at renewal matters. Because the consumer authorizes a withdrawal (mandate) only once and payments then continue automatically, a structural strength is fewer subscription cancellations caused by card expiry or re-authentication.

Once the consumer submits a one-time debit authorization (mandate), funds are withdrawn from their euro account at each billing cycle at the merchant's request — this is a pull-based method. Unlike card payments, the mandate serves as the basis for the transaction instead of per-transaction authentication. Hecto Financial receives the withdrawn funds, converts them, and settles with the Korean merchant in whichever of USD, KRW, or JPY was selected.

Through Hecto Financial, a Korean merchant can consider building out a flow for collecting SEPA mandates and requesting withdrawals. The subscription billing cycle, a risk policy that accounts for the 8-week refund right, and fees and settlement terms vary by industry and transaction structure, so these need to be confirmed before signing the contract.

• Business registration country

  Confirm whether a contract is available under a Korean business registration

• Sales channels

  The integration method and priorities differ depending on your online sales channel mix, such as an owned storefront, open marketplaces, or a mobile app

• Product categories

  Check in advance whether your products fall under a restricted category under SEPA Direct Debit's merchant policies

• EU regulatory compliance

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

SDD transactions occur in euros (EUR), and Hecto Financial receives and converts these funds before settling in whichever of USD, KRW, or JPY was chosen at the time of contracting. A crucial point to note is that under SEPA rules, the consumer can request an unconditional refund within 8 weeks of the withdrawal date, with no reason required. Because this creates a chargeback-style risk where funds already settled can later be reclaimed, a settlement holdback and risk policy that accounts for this 8-week window must be finalized at the contract stage. Also keep in mind that this right is separate from the 14-day right of withdrawal for EU remote sales.
