Allow me to share some information on how you can customized and memorized your A/P Aging Summary Report in QuickBooks Desktop.
The A/P Aging Summary report displays how much you owe to your vendor and how much of your balance is overdue. Oftentimes, we want to fuse the Current and 1-30 days column thinking that they are just showing the same information.
The current column shows any vendor bill that is not yet due. While the 1-30 columns displays anything past due by the number of days that passed after the due date. Thus, the reason there's no way to merge these columns. However, you can always change the interval days in the report.
