There is an important distinction to make first. Domestic recurring debits and transfers in Hungary run on forint-based local infrastructure, since instant AFR payments are mandatory across all banks under the supervision of the central bank, MNB, and bank-transfer culture is strong in this market. SEPA Direct Debit, by contrast, is a pan-European scheme built around euro-denominated accounts, so in Hungary it only works for customers who use a euro account — for example, employees of foreign companies, consumers near the border who maintain a euro account alongside their local one, or B2B customers billed in euros. This is not a mass-market instrument for Hungary, and that is the starting point for any adoption decision.

Given this constraint, the best fit is subscription SaaS, recurring-delivery, or membership businesses billing customers located in Hungary in euros. Once a mandate is collected, funds are debited automatically each billing cycle, which lowers the failure rate on recurring payments. If you are targeting the general Hungarian consumer market, it is more realistic to lead with the card and wallet methods in the comparison table below and treat SDD as a supplementary line for customers who hold euro accounts.

The flow of SDD runs in the opposite direction from card payments. Once the consumer submits an IBAN and signs a mandate (debit authorization), the merchant pulls the payment from the consumer's euro account each billing cycle, and processing takes a cycle measured in bank business days, so it is not an instantly confirmed payment. Once the euro (EUR) funds have been debited, Hecto Financial receives them, converts the currency, and settles with the Korean merchant in whichever of USD, KRW, or JPY was agreed under contract. Preparing compliant mandate wording and meeting the retention requirements are the key preparation steps for integration.

Through Hecto Financial, you can set up recurring payments that include SDD mandate collection and debit processing, without needing to build a SEPA creditor scheme directly as a Korean corporation. That said, for Hungarian customers this method only applies to those who hold a euro account, so you should estimate the size of your addressable customer base and confirm support terms (settlement cycle, fees, currency options) before signing a contract.

• Business registration country

  Confirm contract eligibility for Korea-registered businesses

• Sales channel

  Integration method and priority differ depending on your online sales channel mix — owned storefront, marketplace, mobile app, and so on

• Product category

  Check in advance whether your products fall under a category restricted by the SEPA Direct Debit operator's merchant policy

• EU regulatory compliance

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

SDD funds are debited in euros (EUR) from the consumer's euro account, received by Hecto Financial, converted, and settled with the Korean merchant in whichever contracted currency — USD, KRW, or JPY. The risk you must understand is the refund right. Under SEPA rules, a consumer can request a no-questions-asked refund from their bank for up to 8 weeks after the debit date, meaning even revenue that has already been settled can be clawed back afterward. Claims of unauthorized debits can be disputed for up to 13 months. On top of this, the EU's 14-day right of withdrawal for distance sales may apply separately, so design your delivery/fulfillment timing and billing timing conservatively, and set up standards for provisioning against uncollectible amounts.
