Is there a way to get a list or report of expenses that have not been matched to the bank transactions?

Yes, there's a way of getting this type of list, j-marshall. 

You can go to the bank register where the expenses are listed. Then, export them to Excel so you can see which are not yet matched to a downloaded banking transaction. Here's how:

1. Open your Chart of Accounts. 
2. Look for the bank account and click Account history under the Action column.
3. Click the Export icon in the upper-right hand corner.

Once exported, go to the Added in Banking column. Transactions which doesn't have Manually added in that column means they're not yet matched to any banking transactions. 

I'm just around the corner if you need more help with your banking transactions.
