Why is a bank account needed too?
Adding a bank account to the Vendor Pay account
The recommended payment method for Vendor Pay is the American Express Card.
However, the ability to pay a vendor via ePayment (ACH) or Check is also available with Vendor Pay. ACH and Check payments are funded via a bank account linked to the Vendor Pay account. This will allow for payments to be made to vendors who do not accept payments by American Express Card yet.
The Receivables Solution
Since Vendor Pay also offers a Receivables solution, a bank account can be added and set as the default method to receive payments from customers.
