My checking account organization has definitely been a work-in-progress. I use both a debit card and actual checks (for bills), so a system has to be in place to make sure everything is accounted for and correct.
So, why do I have to organize my checking account?
Well, about six months ago, I lost my checkbook register and I had no idea what the balance was in my account. I felt like I was losing my mind for several days without my handy register. Luckily, I found it, but I vowed from that point on that I would do better about my finances.
I keep my checkbook in a Vera Bradley checkbook cover.
My checking account and finances contained in it are organized in a detailed process that I follow faithfully.
