One corporate payment from pain.001 initiation through pacs.008 execution, status, settlement, exceptions, and camt account reporting — with every conditional step labelled.
Treasury sends the payment instructionAsha Traders treasury → Bank Alfa (debtor agent) · pain.001
Asha Traders asks Bank Alfa to pay one supplier. The pain.001 is a customer instruction, not an interbank payment and not proof that funds moved.
02Processing
Bank Alfa validates the instructionBank Alfa (debtor agent)
The bank checks authority, account and address data, duplicate references, available funds, cut-off time, and sanctions-screening results before accepting the instruction.
Screening checkpoint: Customer-payment screening — Debtor, creditor, agents, addresses, and remittance data are screened before release.
A pain.002 says the instruction passed the reported checks and was accepted for processing. It does not say the supplier has been credited; banks choose which lifecycle statuses their service reports.
04Posting
Bank Alfa debits the corporate accountBank Alfa (debtor agent)
Bank Alfa books the customer debit. The debit and the interbank settlement are separate ledger events and can occur at different times under the account agreement.
DR Asha Traders USD operating account — USD 125,000.00
Where the service provides it, a camt.054 reports the booked debit promptly and carries structured references for cash application. It reports an account entry; it does not create the entry.
06Message
Bank Alfa sends the interbank paymentBank Alfa (debtor agent) → Meridian Bank (correspondent) · pacs.008
Bank Alfa turns the accepted customer instruction into a pacs.008. The UETR, end-to-end reference, parties, agents, amounts, and remittance data identify the same business payment on the interbank leg.
07Processing
Meridian validates and screens the paymentMeridian Bank (correspondent)
The correspondent applies CBPR+ validation, sanctions screening, serial-routing checks, and an account-position check before it books or forwards the payment.
Screening checkpoint: Correspondent screening — Every bank in the chain makes its own decision; an upstream pass does not bind a downstream bank.
08Settlement
The correspondent settles the interbank legMeridian Bank (correspondent)
Meridian debits Bank Alfa's USD account and credits Nordbank's USD account. This book transfer is the value movement; the pacs.008 is the instruction describing it.
This teaching corridor uses correspondent-book settlement in commercial bank money. Other CBPR+ payments may use different correspondents or market infrastructures.
DR Bank Alfa USD account at Meridian — USD 125,000.00
CR Nordbank USD account at Meridian — USD 125,000.00
09Message
The payment reaches NordbankMeridian Bank (correspondent) → Nordbank (creditor agent) · pacs.008
Meridian forwards the serial customer credit transfer with the original UETR and structured payment data so Nordbank can match the instruction to the incoming value on its correspondent account.
10Processing
Nordbank validates the incoming paymentNordbank (creditor agent)
Nordbank checks the supplier account, screens the payment, and confirms that the incoming value and instruction can be matched before it credits the customer.
11Posting
Nordbank credits the supplierNordbank (creditor agent)
Nordbank books the credit to Northstar Components. The supplier can now use the funds; any later recovery request must respect that settled and credited state.
An interbank status closes the processing loopNordbank (creditor agent) → Bank Alfa (debtor agent) · pacs.002
Where the bilateral service provides a positive pacs.002, ACCC reports that the creditor account was credited against the original pacs.008. A transport acknowledgement and a business payment status are different signals.
If contracted, camt.052 gives Asha an intraday view of balances and entries, including the debit and its references. It is an interim report, not the final daily statement.
Bank Alfa sends the booked statement for the account. Treasury matches the camt.053 entry to its pain.001 transaction using the end-to-end and account-servicer references.
What this simplifies: A teaching composite across customer initiation, CBPR+ execution, Case Management, and bank-to-customer reporting. Not every bank sends every status or report, and mutually exclusive reject, return, and recall outcomes are shown as branches.

MESSAGES, SAMPLES, AND GOVERNING SOURCES
These resources cover the message conversations explicitly authored in this flow. Scheme-neutral teaching files still require validation against the profile used in production.
An XSD checks XML structure. A usage guideline adds profile rules, conditional fields, code restrictions, and business controls. XSD-valid does not mean scheme-compliant.

Used wherever diagrams, scenarios, figures, or example values are didactic constructions rather than sourced facts; every such use carries a simplifications disclosure. All people, companies, banks, and list entries in examples are fictional.
