Made a mistake on Quickbooks with reconciling accounts and need a redo?
Fortunately Quickbooks offers the option (only to the accountants/bookkeeper) to undo any reconciled accounts and reconcile them properly.
I recently ran into this situation with my clients books; expenses being wrongly categorized AND mis-matched to the wrong payment method.
Here's a screenshot of where you go to undo a month.
Note** if you want to undo September, you first have to undo October. Same if you want to undo January, you have to undo all the months after.
