Preserving Data When Importing Orders Into QuickBooks
When exporting order and customer info from my Order Management System to QuickBooks, how do I prevent existing customers' new orders from over-writing their existing information?
When Exporting Order/Customer information from Nexternal to QuickBooks, only information that has changed will be updated. Therefore, if you have additional fields at the customer level in QuickBooks, that data will not be lost. If information in Nexternal is different than information in QuickBooks (such as a phone number), QuickBooks will update to the current information. Past orders are always left unaltered.
