It’s important you don’t connect bank feeds or manually import any bank statement data for your conversion period. The steps below will ensure all the balances are correct.
As QuickBooks Online doesn’t provide us with the ability to convert transactions as reconciled, you’ll need to tell it to mark all relevant transactions up to the conversion date as reconciled. This will correct the current reconciled status of transactions and means QuickBooks Online will only consider future transactions for reconciling.
From the Dashboard, under Bank Accounts, click the name of the bank account.
You can change the bank as necessary then click Reconcile.
On the next screen click Get Started but when asked if you want to Reconcile like a pro, select the option to close the popup.
Reconcile an account will display. Complete the Ending Balance and Ending Date fields as they were on the date you converted to.
Leave the rest of the form blank and select OK.
You will see a list of transactions up to the statement ending date entered on the previous step. Select the top radio button to reconcile all the listed transactions.
If there are unreconciled transactions, make sure to leave them deselected.
Select Finish Now.
It’s important to repeat this process for all bank accounts in QuickBooks Online.
