Is it possible to show invoice numbers in die description column when importing csv bank transactions?

Hi there, @belinda3.

Yes, you can put the invoice number in the Description column. It should be like this format "Inv no. 1098." If this is more than that, there's a possibility that the complete details in the description will not show under the For review tab on the Banking page. 

I've added a screenshot to show the difference before and after it was uploaded to QuickBooks:

You should not worry if your bank transactions will not categorized properly. QuickBooks will find any potential matches within the system and will put a notification in the bank transaction that there's a similar transaction found.
