I keep getting the error below when creating an invoice Error: No bank account details found. [Buyer Name] requires this on all invoices.

The cause of the issue is due to the following reasons:

1. Your customer has enabled the transaction rule Require suppliers to include bank account details on invoices.
2. Beneficiary Bank details are missing in the Remittances section of your supplier account.

• If you have not added any Bank details under EFT/Check Remittances under Remittances. Kindly add the remittance information,
• If you have already added the details, make sure the Beneficiary Bank details are filled in EFT/Check Remittances section.

The transaction rule Require suppliers to include bank account details on invoices does not apply to US suppliers.

Select Wire as Payment Methods if you are using wire transfer, and ensure SWIFT Code is not blank.
