SEPA Clearing and Settlement

SEPA Payment Messages
Introduces the ISO 20022 pain, pacs, and camt message families and explains how SEPA schemes adapt them for euro payments.
SEPA Payments Schemes
Defines the difference between a payment scheme and a processing system before introducing SEPA's four principal rule sets.
SEPA stakeholders
Organizes the major European institutions, industry bodies, and operational participants that govern and deliver SEPA.
Introduction to SEPA
Explains SEPA's purpose, euro-only scope, geographic boundaries, and goal of making cross-border euro transfers resemble domestic payments.
ACK, NACK, and the Payment Status Report (pacs.002)
An ACK (acknowledgement) confirms a message was accepted and a NACK (negative acknowledgement) reports it was rejected, while the pacs.002 payment status report tells the sender whether the payment itself was accepted, rejected, or is still pending, with reason codes.
Verification of Payee
Explains how Verification of Payee compares the beneficiary name a payer enters against the name held on the account before a euro credit transfer is authorised, and what a match, close match, or no match means for the payer.
SEPA Direct Debit core
Describes the pull-payment model of SEPA Direct Debit Core: how a signed mandate authorises collection, how a collection travels as a pain.008 and interbank pacs.003 message, and the roles the creditor and debtor banks play.
SEPA Direct Debit exceptions and refunds
Explains how a SEPA Direct Debit collection can fail or unwind — rejects, refusals, returns, refunds, and reversals — including the eight-week no-questions refund window for authorised collections and the thirteen-month window for unauthorised ones.
SEPA Direct Debit: B2B versus Core
The SEPA (Single Euro Payments Area) Direct Debit Business-to-Business scheme differs from the Core scheme: no no-questions refund right for authorised collections, a mandatory mandate check by the debtor's bank, and eligibility limited to non-consumer payers.
Request to Pay and e-mandates
What Request to Pay is as a messaging layer that lets a payee ask a payer to pay while the payer stays in control, and how e-mandates digitise direct-debit authorisations over existing rails.
STEP2: the pan-European ACH
STEP2 is EBA CLEARING's pan-European automated clearing house: it validates and clears standard SEPA credit transfers in cycles, calculates each participant's net position, and settles those positions in central-bank money in TARGET2 — the clearing layer beneath a non-instant SCT.
