SEPA DIRECT DEBIT

No mandate, no pull: a Core direct debit returned

Trigger: Bank Alfa finds no valid mandate on file for the incoming collection (or the account cannot cover it).

Contributor Shubham Mathure

What operations sees first: A collection that reached the debtor bank cannot be applied; operations sees a return with a no-mandate reason code.

WHERE IS THE MONEY?

Never stayed with the biller — returned before or shortly after settlement; Riya was not debited.

DID SETTLEMENT HAPPEN?

The collection was reversed by a separately settled return.

WHO ACTS NEXT?

Bank Alfa (debtor bank) Asha Traders obtains a fresh, valid mandate from Riya before attempting to collect again.

PLAY THE EXCEPTION

Trigger: When Bank Alfa checks the incoming collection it finds no valid mandate on file for Riya (or the account cannot cover it), so it must send the collection back rather than complete the debit.

STEP 1 / 11INTERNAL

Asha Traders confirms the mandate

Asha Traders (creditor / biller)

Before pulling any money, the biller checks it holds a valid mandate that Riya signed authorising these collections. The mandate — not the invoice — is what permits the pull; no mandate means no right to debit.

Checks

  • Mandate reference on file
  • Debtor's IBAN matches the mandate
  • Mandate not cancelled or expired

  1. 01Processing
    Asha Traders confirms the mandateAsha Traders (creditor / biller)

    Before pulling any money, the biller checks it holds a valid mandate that Riya signed authorising these collections. The mandate — not the invoice — is what permits the pull; no mandate means no right to debit.

  2. 02Message
    Asha Traders pre-notifies Riya of the collectionAsha Traders (creditor / biller) → Riya (debtor / customer)

    The creditor tells the debtor the amount and the due date in advance, so Riya can expect the debit and keep the account funded. This is a courtesy notice ahead of the pull, not the money movement itself.

  3. 03Message
    Asha Traders submits the collection to NordbankAsha Traders (creditor / biller) → Nordbank (creditor bank) · pain.008

    Here is the mirror image of a credit transfer: the instruction starts at the payee. Asha Traders sends a pain.008 collection request to its own bank, Nordbank, to go and pull the funds from Riya's account.

  4. 04Message
    Nordbank submits the interbank collectionNordbank (creditor bank) → STEP2-T (CSM) · pacs.003

    Nordbank converts the customer collection into an interbank pacs.003 and submits it to the clearing and settlement mechanism, which will route it toward the debtor's bank to be collected on the due date.

  5. 05Clearing obligation
    The CSM calculates obligationsSTEP2-T (CSM)

    On the due date the CSM validates the collection and includes it in a clearing cycle, calculating who owes whom. In a pull this obligation runs from the debtor's bank to the creditor's bank — the reverse of a credit transfer.

    Clearing produces obligations only. Nordbank does not have Asha Traders' money yet — that waits for settlement.

  6. 06Settlement
    Positions settle in central bank moneyBank Alfa (debtor bank) → Nordbank (creditor bank)

    The calculated positions settle across the banks' accounts at the central bank. Money moves from Bank Alfa (debtor side) to Nordbank (creditor side) — funds flowing debtor to creditor even though the instruction came from the creditor.

    • DR Bank Alfa settlement account — EUR 480.00
    • CR Nordbank settlement account — EUR 480.00
  7. 07Posting
    Bank Alfa debits RiyaBank Alfa (debtor bank)

    Bank Alfa books the debit against Riya's account for the collected amount. This is the customer-facing side of the pull: money leaves the debtor's account because the mandate authorised it.

    • DR Riya's current account at Bank Alfa — EUR 480.00
  8. 08 · EXCEPTION PATHProcessing
    Bank Alfa cannot apply the collectionBank Alfa (debtor bank)

    Without a valid mandate the pull has no authorisation, so Bank Alfa refuses it. A direct debit without a live mandate is exactly what the return path exists to catch and reverse.

  9. 09 · EXCEPTION PATHMessage
    Bank Alfa returns the collectionBank Alfa (debtor bank) → STEP2-T (CSM) · pacs.004

    A pacs.004 carries the amount and a reason code (here, no valid mandate) back along the original route, referencing the collection Nordbank submitted.

  10. 10 · EXCEPTION PATHSettlement
    The return settles backNordbank (creditor bank) → Bank Alfa (debtor bank)

    If settlement had already run, the return is cleared and settled in its own right — money moves from Nordbank back to Bank Alfa in central bank money.

    • DR Nordbank settlement account — EUR 480.00
    • CR Bank Alfa settlement account — EUR 480.00
  11. 11 · EXCEPTION PATHPosting
    Nordbank reverses the biller creditNordbank (creditor bank)

    Nordbank claws back the amount from Asha Traders and passes the reason code on, so the biller learns the collection failed for want of a valid mandate.

    • DR Asha Traders' account at Nordbank — EUR 480.00
  12. OUTCOME
    Funds
    Never stayed with the biller — the collection was returned before or shortly after settlement.
    Settlement
    The collection was reversed by a separately settled return carrying the reason code.
    Who acts next

THE TIMELINE

    Submits Asha Traders' collection interbank toward Bank Alfa on the due date.pacs.003
  2. 02Bank Alfa (debtor bank)
    Checks the collection and finds no valid mandate authorising the pull, so it must refuse it.

    A direct debit without a live mandate is exactly what the return path exists to catch.

  3. 03Bank Alfa
    Returns the collection with the reason code back along the original route.pacs.004
  4. 04Nordbank
    Reverses the biller credit and passes the reason on to Asha Traders.

Resolution: Without a valid mandate the pull has no authorisation. The collection is returned and, if it had settled, reversed by a separately settled return carrying the reason code.
