AP Aging uses Invoice Date and is intended for managing payables (not for balancing with the GL). 

AP Trial Balance uses Transaction date and is designed to balance with the GL. The invoice date doesn't matter.  (However, there may be rare data patterns where Trial Balance report filters are imperfect... like if you backdate the payment posting date to before the invoice's posting date... but that should never happen.  Prepayments should be posted separately, and applied later).

Kevin, So are you saying that the A/P Aging will never balance to any other report other than the current day with A/P trial balance (if all transactions have stopped for a closing) ? It will never match the same period Balance sheet, GL A/P ending balance history, or GL A/P  detailed report. All of which match each other but none of which match the aging report.  It's merely a means to keep track of invoices and age them for managing them?

AP Trial Balance is for balancing with the GL.

AP Aging is for managing your payables.  It "might" balance with the GL, if you always set Invoice Date = Posting Date, but that doesn't happen in the real world.

The two reports have different purposes.

I don't readily work with AP daily but that's what I am finding out. Thank you for confirming. Brenda
