FAQ

What is a SEPA payment integration partner?

A SEPA payment integration partner is an infrastructure provider that gives fintechs API access to SEPA Credit Transfer and SEPA Instant rails without requiring direct clearing scheme membership. This lets companies embed euro payment functionality into their own platforms in weeks rather than years.

How is SEPA Instant different from standard SEPA transfers?

SEPA Instant settles euro transfers in under 10 seconds, 24 hours a day, 7 days a week, compared to standard SEPA Credit Transfer, which follows a next business day settlement cycle. Regulation increasingly requires institutions offering standard SEPA transfers to also support SEPA Instant.
