IBAN discrepancies usually result from differences in where Payhawk pulls the account information, namely: - For supplier-related expenses, Payhawk retrieves the IBAN from the supplier profile in Payhawk. - For reimbursements, Payhawk retrieves the IBAN from the user profile. If this information is outdated, discrepancies can occur. To resolve this issue, try the following approaches: - Update outdated reimbursement data - Employees have to ensure their profile contains the correct and current IBAN. - Payhawk Administrators can manually update outdated IBANs in user profiles to reflect the correct account information. - Review open transactions: - Check reimbursements linked to previously used or incorrect IBANs. - Update the details where needed to ensure consistency and avoid failed transactions.
