Hi,

Make sure that:

1) ALL your Zen Cart products have a Model. If it is missing, you need to add it. The Model is like a SKU or part number. If you make it equal to the QB Item Name, you will not need to do any matching.

2) Read the manual completely and do not skip doing the configuration and set-up/match as needed. Just like Zen Cart and Quickbooks, you must fully configure QBI before trying to use it.

3) Make sure that any discount coupons or gift vouchers have been set up properly in QBI.

4) Open the iif file in Excel. You will be able to see what product or products are missing from each order. The transaction is likely not in balance because one of the line items is missing.

Thanks,
Adam
