Never make a Bill to pay later. The error is using a Bill at all. @Charies_M The issue is that a Bill implies the CC account already got paid; the difference is hiding in AP. You don't use Bills for CC processing.

"When I reconcile the credit card the following month the $2,000 doesn't show up on my reconcile screen so it shows I'm $2,000 off. What am I doing wrong?"

When you reconcile and the QB program offers to make a bill. Do Not Let It. Just hit Escape, cancel or the X in the top right corner. Make your own Check entry, for the payment date and amount, when you want to note how much you paid, putting the credit card account in the Expenses tab.

What you are doing now is hiding a liability (CC) in a different liability (AP). You cannot Reconcile the card provider statement, because the rest of the reconciled amount is hiding in AP.

Here's how to Fix it, now. Any Bill against CC that is not paid at all, just delete it. All that is doing is running data in Circles between two liability account types. Now, for any Partially Paid bill, reduce it to the amount paid. Now no open AP exists for the CC, so you Stop using bills entirely.

Using the CC is not AP. It is taking a Micro-loan, and the payment to the card provider is Direct, and not as AP. They are different types of Liabilities.
