Bill To Contacts is used when all of the billings for two or more entities are billed to one “parent” contact. For example if the owner of ABC Company (John Smith) wants his individual return to be billed to ABC Company, Bill To Contacts would allow the WIP and the invoice to be directed to ABC Company. It is important to note that all WIP will still be tracked under each entity individually, but will show in Office Tools Professional under the “parent” entity. This function is located in SETUP>BILLING
