I have the problem when I Import the QBO file to QuickBooks
. As I am adding the transactions to my transaction register, there are duplicates of split transactions for a couple of payees. The split transactions are not maintained under the original transaction (Check Number), therefore when they are Imported each transaction split is duplicated. Also, my expense accounts under chart of accounts are not assigned to each transaction as they were in the QIF file, I have to select the expense account manually for each transaction.
On the converter tool, if you look under the source tab it shows the correct information on my split transactions and account assignments for each transaction.
I hope this helps, if you need further information let me know.
