DBSync stores the unique value from QuickBooks in a field called QuickBooks id which is an external id in Salesforce. When reading a data with an id let’s say ‘x’ from quickbooks in multiple syncs, if a record with the QuickBooks Id ‘x’ is already present, it will update the same record instead of creating new ones. Hence creation of duplicates are prevented.
