If you notice a difference in your bank reconciliation in NetSuite, you can review and correct it by following these steps.
Navigate to the Bank Reconciliation page
Go to Transactions > Bank > Reconcile Bank Statement.
Select the bank account you want to review (e.g. 1000 Checking).
Access Reconciliation History
Click History.
This opens the Reconciliation History screen.
If you don’t see records, enter an early date in the From field and click Refresh to display all reconciliations.
Identify the Difference
Look for any reconciliation that shows a dollar difference.
Click the difference amount to open that reconciliation.
Review and Adjust
Check which transactions may have been edited or changed after the reconciliation.
Select (check off) those transactions in the reconciliation box.
Confirm that the Difference now shows 0.00.
Save and Verify
Click Save to update the reconciliation.
Return to the Reconciliation History screen.
Backdate the From field and click Refresh again.
Confirm that the difference is now zero.

This issue usually occurs when transactions (such as deposits) are edited after a reconciliation has already been completed.
Always review changes carefully before saving to ensure accuracy.
