California-based Bill.com launched a billing feature that allows small businesses and accountants to invoice their customers via snail mail.

“Bill.com’s Accounts Receivable (AR) update enables users to send printed bills to their customers via U.S. mail at below the cost of what a typical company would spend printing, stuffing and mailing invoices.”

This new service will benefit those who prefer paperless billing methods by allowing them to send invoices to customers who still use paper invoices.
