The key to easier bill paying is consistency - in who pays the bills, when, where and how:
* One Person Should Pay All The Bills. But make sure that the non-bill-paying spouse understands the system.
* Pay Bills Twice A Month, on the same days every month.
* Set Up One File for the first half of the month and another for the second. When bills come in, file by due date. If a bill has no due date, put it with the group to be paid first.
* Choose A Convenient Place To Pay Your Bills and use it routinely. A bill-paying kit with all needed supplies should be kept there.
* Pay All Bills Of The Same Type In The Same Way. Charge all medical expenses on the same card, for example. Online payment saves time and stamps, while programs such as Quicken can be used to print your checks and keep records.
* After Paying A Bill, Put The Date Paid and check number on the part that you retain. File by category. Keep only the current year's bills and one year back. One important exception are the records you need for tax purposes.
