Crispety- I love Bill Pay too, but I still register my check information manually on the checkbook transaction register. I like to double check my checkbook and my online account to make sure it balances.
I don’t ever want to bounce a check. The fees are incredible. My bank charges like $35 for a bounced check. This is for each time that the checked is bounced. I have never bounced a check, and I hope I never will.
