Only the following listed fields sync back and forth between JobNimbus and QuickBooks. There is currently no plan to add any fields to the sync process such as Ship To Address or Notes fields. You may ask for fields to be added through the Feedback process so that they can be voted on and prioritized.
*Contact name is on the records' address line 1 so those financial records will have the contact name in the address line automatically inserted in QB (this was implemented due to customer demand). If you select QB as a preference and the name is not there it should not sync with the name there.
*Estimates/Invoices have an option to choose to sync in draft status or not.
