When Arkaio detects that a vendor has new bank details in Intacct, its bills are blocked until the change is approved. This is the main safeguard against vendor impersonation fraud ("IBAN change" fraud).

IBAN approvers tab: who can approve a bank detail change
- Only the people listed here can approve a change.
- The number of approvals required is set in the settings ("Approvals for an IBAN change"); with 2, two different approvers are needed.
- Alerts are handled in the "Bank detail change alerts" menu.
Important — Do not designate as IBAN approvers the people who enter vendors in Intacct: whoever changes an IBAN must not be able to approve it.
