Wise-Sync will set the Billing Contact information in your accounting system based on the following hierarchy.
- The Billing Contact seclected for the Bill To Company in ConnectWise.
- The Primary Contact selected for the Bill to Company in ConnectWise.
If Wise-Sync is unable to return a Billing Contact, then the Primary Contact is used. If the sync is still setting the primary contact even though a billing contact is selected, then ensure that the Billing Contact is active as per the Contact Profile record.
