how to approve supplier bank detail changes in marine procurement?

Approve supplier bank detail changes through a controlled, auditable workflow that verifies the request and prevents incorrect or fraudulent payment instructions from entering the payment process. This is typically implemented as supplier bank detail change approval with segregation of duties between procurement, finance, and accounts payable, supported by supplier bank verification and a bank details audit trail so CFO and IT stakeholders can demonstrate control effectiveness and reduce payment fraud risk.

How Supplier Bank Detail Changes Is Applied

Change request intake and validation: Require a formal bank change request from the supplier, capture the effective date, and validate that the request matches the supplier master record (legal entity name, tax ID, and address) before any approval decision.
Segregation of duties and dual control: Route the change for review by finance (accounts payable or treasury) and a second approver (procurement finance controller or internal control owner) so no single role can both accept and activate new bank details.
Supplier bank verification and out-of-band confirmation: Perform supplier bank verification by confirming the new account details using a trusted channel already on file (for example, a previously validated contact method), reducing the chance of payment redirection scams.
Bank details audit trail and evidence retention: Store the full approval history, documents received, verification steps, and approver identities to create a bank details audit trail that supports internal and external audits.
Payment fraud prevention controls: Apply a hold on payments to the supplier until the change is approved and verified, and block payments if bank details are modified outside the approved workflow.

Operational Impact

Financial control and reduced loss exposure for CFOs: Dual control plus a payment hold prevents incorrect or fraudulent bank instructions from being used in payment runs, limiting direct financial impact and improving confidence in payment accuracy.
Procurement governance and cleaner supplier master data for Procurement Managers: Centralized approval ensures bank changes are reflected only through controlled supplier master updates, reducing downstream disputes, reconciliation effort, and rework in invoice matching.
Audit readiness and system governance for CIOs and IT Managers: A documented bank details audit trail and defined workflow permissions support evidence-based audits, while access control and workflow enforcement reduce the risk of unauthorized changes.

Important to know: Treat supplier bank detail changes as a high-risk event. Even when procurement receives the request, activation should be blocked until finance completes verification and approvals, and the system should prevent payments from using unapproved bank data.
