In Sage 50 Accounts, if you change a bank reconciled transaction since you last reconciled, you can view the transactions that are causing the difference.
When you bank reconcile, you see a message informing you the balance is different, followed by the Reconciliation Difference window:

Take a look at the transactions and compare them to your bank statement, or other records. How you proceed depends on why the transactions are different and why this has happened.
Re-enter the transaction using the buttons at the top of the Reconciliation Difference window.
Once re-entered, click Continue to bank reconciliation and double-click the transaction in the Unmatched transactions window to move it to the Matched transactions window.

Either use the buttons at the top of the Reconciliation Difference window to make up the difference, or correct the existing transaction in Transactions.

Click Continue to bank reconciliation and double-click the transaction in the Unmatched transactions window to move it to the Matched transactions window.


Click Print list to print the details of the transactions.
If you still can't work out why the bank reconciliation is showing a difference, please refer to our guide, Why doesn't my bank reconciliation balance?
