I completely agree.  Why is that a small business who does their own book not have access to the undo reconciliation button. On the desktop version it is available. I have used it in one or more occasions with one company. I have now started working with another company which books are a mess and there are lots of corrections that need to be made. I have reached out to the accountant to undo it as the QB online protocol is and not only does the company get changed to use QB online now they have to pay an accountant to spend time to to do something simple as this.  Not to mention the accountant is new to QB online and spent more time than necessary to figure it out. QB is supposed to be user friendly especially for small businesses. A simple task as this has turned into a 2 weeks of emails and delays making it not so quick bookkeeping.

All I can say is do better QuickBooks!
