Import the statement as bank evidence, then match its rows to the transactions already in your books.
1. Start the reconciliation
Open Accounting → Bank Reconciliation → Accounts. Choose Reconcile for the correct account, or Resume for one already in progress.
2. Enter the statement scope
Enter Start Date, End Date, and the actual Closing Balance. Choose Import Statement and select the bank file.
3. Map the columns
Review Amount Layout, Date Format, Header Row, and description/reference. Use the incoming/outgoing layout when the bank has separate money-in and money-out columns.
4. Check before accepting
Compare several preview rows with the original statement. Confirm dates and signs are correct, then accept the statement rows for reconciliation.
