As the world's largest e-commerce market, the United States is where PayPal's home-market base — the largest share of its hundreds of millions of global active accounts — carries the most weight, and decades of accumulated dispute resolution and buyer protection give consumers a strong sense of trust. Cards, wallets, and BNPL all compete for share, but the habit of turning to PayPal on an unfamiliar site remains firmly in place.

The effect of borrowing this payment trust is especially strong for Korean merchants making their first entry into the US without brand recognition yet, for new direct-to-consumer sites without a review history, and for categories with frequent return disputes. Guest card checkout is accepted alongside account login, so a practical sequence is to lead with PayPal early on, then add cards and wallets as usage data comes in.

When a consumer taps the PayPal button at checkout, they are taken to a login screen and approve the payment using their linked balance, card, or bank account; customers without an account can proceed with guest card checkout instead. Approval is instant, and the proceeds are collected by Hecto Financial in USD, converted, and paid out in the currency selected under the contract. Card-funded transactions are tokenized, so the card number is never exposed to the merchant.

Through Hecto Financial's integration, Korean merchants can consider accepting PayPal without the burden of opening a US-based account. That said, PayPal's seller protection and dispute policies are detailed, and its restricted-category and reserve policies are equally specific, so it's best to confirm terms with the sales team before contracting, based on your product lineup and return-rate data.

• Business registration country

  Confirm contract eligibility for businesses registered in Korea

• Sales channels

  Integration method and priority vary depending on your mix of online sales channels — owned site, marketplace, mobile app, and so on

• Product categories

  Advance confirmation is needed on whether your category falls under PayPal's merchant restrictions

• Local regulatory compliance

  Confirmation is needed on compliance with US payment and foreign exchange regulations, including federal and state consumer protection rules and card network rules (see official sources below)

Proceeds from US consumers' PayPal payments are collected by Hecto Financial in USD, converted, and paid out in one of three currencies — USD, KRW, or JPY — as fixed under the contract. Refunds follow the original transaction back to the consumer's PayPal balance or original funding source, and since PayPal's dispute process may run in parallel, dispute response deadlines should be built into your operating process.
