ISSUE

When importing Invoices or Sales Receipts with Transaction Pro Importer and the Customer's address is different from the default address that has been setup in the Customer file in QuickBooks Desktop (QBDT), the Customer file is updated with the imported address.

OR

When importing Bills or Checks with Importer and the Vendor's address is different from the default address that has been setup in the Vendor file in QBDT, the Vendor file is updated with the imported address.

RESOLUTION

To prevent this from happening, select the following OPTION on the BASIC tab in Importer - DO NOT UPDATE ADDRESSES ON EXISTING QUICKBOOKS LIST ITEMS. This will prevent the default addresses in the Customer or Vendor file from being updated if the import file includes a different address (see image below).
