- Click Bank Reconciliation in the sidebar. It’s under Sales & Billing; click the ••• there if you can’t see it. On the Transactions tab, find the matched line. Its status is, for example, Expense recorded.
- Click the orange Unlink Transaction button.

- Under Removal Option, Remove link only is selected: only the link is removed and the payment or expense stays. Click Confirm. The bank line goes back to Not assigned.

Note: the window can also offer Remove link and delete invoice payment(s) recorded (deletes only payments created during reconciliation; the invoice status updates) or Remove link and delete expense. If these options aren’t shown, remove the link only and then delete the expense yourself (see Delete Expense).
