SEPA DIRECT DEBIT

No refund by design: an authorised B2B collection stands

Trigger: After being debited for an authorised B2B collection, the business debtor asks its bank for a refund.

Contributor Shubham Mathure

What operations sees first: A corporate customer expects a consumer-style reversal; operations must explain the B2B scheme does not provide one.

WHERE IS THE MONEY?

Debited from the business debtor and credited to Asha Traders — the money stays where it settled.

DID SETTLEMENT HAPPEN?

Settlement stands; no scheme reversal applies to an authorised B2B collection.

WHO ACTS NEXT?

Business debtor The debtor raises a commercial dispute with Asha Traders directly; there is no scheme refund to invoke.

PLAY THE EXCEPTION

Trigger: After being debited for an authorised collection, the business debtor asks its bank for a refund.

STEP 1 / 10INTERNAL

The debtor signs a B2B mandate

Business debtor → Asha Traders (creditor)

The business debtor signs a B2B direct debit mandate authorising Asha Traders to collect from its account. Unlike Core, this authorisation is business-only and carries no consumer refund right.

  1. 01Processing
    The debtor signs a B2B mandateBusiness debtor → Asha Traders (creditor)

    The business debtor signs a B2B direct debit mandate authorising Asha Traders to collect from its account. Unlike Core, this authorisation is business-only and carries no consumer refund right.

  2. 02Processing
    The debtor registers the mandate with Bank AlfaBusiness debtor → Bank Alfa (debtor bank)

    The B2B scheme requires the debtor to lodge the mandate details with its own bank. Bank Alfa stores this so it can later check every collection against a mandate it already knows about.

  3. 03Message
    Asha Traders submits the collectionAsha Traders (creditor) → Nordbank (creditor bank) · pain.008

    Asha Traders instructs Nordbank to collect the invoice. A corporate creditor sends a pain.008 collection request naming the debtor and referencing the signed mandate.

  4. 04Message
    Nordbank sends the interbank collectionNordbank (creditor bank) → Clearing & settlement mechanism · pacs.003

    The creditor bank converts the instruction into an interbank pacs.003 collection and submits it to the clearing and settlement mechanism for routing to Bank Alfa.

  5. 05Processing
    Bank Alfa verifies the mandateBank Alfa (debtor bank)

    This is the defining B2B step: the debtor bank must check the incoming collection against the mandate it registered before it debits. Core has no such mandatory pre-debit mandate check.

  6. 06Clearing obligation
    The CSM calculates positionsClearing & settlement mechanism

    The CSM validates the collection and includes it in a clearing cycle. Each participant's obligations are calculated — this creates who-owes-whom, not yet a movement of money.

    Clearing produces obligations. No money has moved yet — that only happens at settlement.

  7. 07Settlement
    Positions settle in central bank moneyBank Alfa (debtor bank) → Nordbank (creditor bank)

    The calculated positions settle across the banks' settlement accounts at the central bank. Only now has money finally moved from Bank Alfa to Nordbank for the collection.

    • DR Bank Alfa settlement account — EUR 9,600.00
    • CR Nordbank settlement account — EUR 9,600.00
  8. 08Posting
    The debtor's account is debitedBank Alfa (debtor bank)

    Having verified the mandate, Bank Alfa books the debit on the business debtor's account. The pull has now taken money from the debtor to fund the settled collection.

    • DR Business debtor's account at Bank Alfa — EUR 9,600.00
  9. 09 · EXCEPTION PATHProcessing
    The debtor asks Bank Alfa for a refundBusiness debtor → Bank Alfa (debtor bank)

    Used to a consumer-style refund, the business debtor asks Bank Alfa to reverse the settled collection. This tests what the B2B scheme actually allows for an authorised debit.

  10. 10 · EXCEPTION PATHProcessing
    Bank Alfa explains there is no refund rightBank Alfa (debtor bank) → Business debtor

    For an authorised B2B collection the scheme grants no right to a refund, unlike SDD Core's eight-week no-questions refund. Bank Alfa cannot pull the settled money back on request.

  11. OUTCOME
    Funds
    Debited from the business debtor and credited to Asha Traders — the money stays where it settled.
    Settlement
    Settlement stands. The B2B scheme provides no refund reversal for an authorised collection.
    Who acts next
    Business debtor — The debtor pursues a direct commercial dispute with Asha Traders, since no scheme refund applies.

THE TIMELINE

  1. 01Business debtor
    Asks Bank Alfa to reverse an authorised B2B collection of EUR 9,600.00 that already settled and posted.
  2. 02Bank Alfa (debtor bank)
    Explains the B2B scheme grants no right to a refund for an authorised collection, unlike SDD Core's 8-week refund.

    The debtor bank already verified the mandate before debiting; that pre-debit check is the B2B safeguard, in place of a later refund.

  3. 03Business debtor
    Pursues the matter as a direct commercial dispute with the creditor, Asha Traders.

Resolution: The B2B scheme deliberately trades the consumer refund right for a mandatory pre-debit mandate check. An authorised collection is final; the only remedy is a commercial dispute with the creditor.
