Hi,

Steps to Perform Bank Reconciliation in Odoo:

    Access Reconciliation View:

        Go to Accounting Dashboard.

        Click on the Bank Journal name or the Reconcile Items button.

    Review Transactions:

        In the Transactions section (left), select a bank transaction to reconcile.

    Define Counterpart Entries:

        In the Counterpart Entries section (bottom right), choose a method:

            Match Existing Entries: Use pre-selected matches.

            Batch Payments: Reconcile grouped payments.

            Manual Operations: Manually select accounts and amounts.

            Reconciliation Model Buttons: Use custom buttons for frequent operations.

    Balance the Resulting Entry:

        In the Resulting Entry section (top right), ensure the transaction is balanced.

        Add another entry or write off any remaining amount if needed.

    Validate or Mark as To Check:

        Click Validate to confirm reconciliation.

        Use To Check if unsure, and revisit later.

    Repeat for All Transactions:

        Continue matching and validating until all transactions are reconciled.

Hope it helps

I've just provided the answer on the same question here.

Just the summary:

In Odoo, reconciliation means linking each bank transaction to the correct document (e.g., customer invoices, vendor bills, or other entries). Transactions can be imported by bank synchronization, file upload (CSV/OFX), or manual entry — the method doesn’t matter as long as they are in Odoo. Special cases like customer prepayments or loans require using advance payments or accounts with Allow Reconciliation enabled. The best practice is to keep transactions up to date and reconcile regularly to avoid errors.

Good luck!
