Send an invoice to a customer with US Mail. Mailing an invoice is useful when you want to send an invoice to a customer that is not in the BILL network.

The Customer billing address is required for mailing an invoice.

• billAddressCountry must be US
• billAddressCity
• billAddressState
• billAddressZip

BILL prints the invoice and mails it to the customer. The expected delivery date is 3-5 business days. Keep your organization address current in case the mail cannot be delivered to the customer.
