I don't understand "bank feeds".  I understand reconciling your books to the bank.  But reconciliation does not "add" any transactions to your accounting system.

Bank Feeds on the other hand enable you to "add" transactions.  Can someone give me a few examples of when, as a disciplined business you would have a transaction coming from the bank that's not already in your QB system?  And I'm not talking bank fees and interest.  

As a businessman, I want to originate all transaction in my business - not from the bank.  I am confused on the reason why anyone would let a bank feed create a transaction in their accounting system.

Please enlighten me.  Thanks.
