1) Reconcile your bank accounts to your accounting system all the time. Constantly. "I can't stress this enough!"
- Don't wait for the month end statement (although you also should have one of your monthly reconciliations be to the statement).
- You can reconcile to the online balance every day, or every two days, or every week. It makes the bookkeeping SO much easier.
- When I meet a bookkeeper who says they reconcile the bank account every day, that's an immediate high-five. I know I'm dealing with someone who knows what they're doing.
