Does all transactions disappear once reconciled? I see them on Profit

Hello, eaglerocks47. 

I'll provide more details about the reconciled transactions. 

Those reconciled transactions won't disappear from your QuickBooks Online account. They'll stay in your books until they're manually deleted. 

Are you looking at the reconciliation screen? If so, those reconciled transactions won't show up. This is normal, and if you want to see them, you'll want to pull up the Reconciliation report. Here's how: 

1. Go to the Chart of Accounts page, then click the Reconcile tab. 
2. Click the History by Account link.
3. Find the reconciled period, then click View report.

You can review the list of transactions you reconciled within that period. The report will also let you know if there were any changes with them. 

If not, I take it that you're looking at the Profit and Loss report. Unlike the reconciliation screen, they will always show up on all reports. 

If you need a reference about the reconciliation process, feel free to read this article: Reconcile an account in QuickBooks Online.
