WHOInc's ONE Invoice™ program is designed to simplify the process of ordering and paying for workplace supplies. Instead of dealing with multiple invoices from various orders placed throughout the month, ONE Invoice™ consolidates everything into a single, easy-to-manage invoice that arrives at the end of each month.

This means no more keeping track of numerous bills, due dates, and payments. You can place as many orders as needed, whenever you need to, without worrying about a constant influx of invoices.
