Hi Muhammad Faisal,

Thank you for your question!

Yes indeed:
once the invoice journal item is reconciled with the bank statement, the invoice is marked as paid.
It is, then, not necessary to mark the invoice as paid before, especially if your bank statements are often synchronized with, or imported in your Odoo database.

You can learn more about this in the "Bank Statements and Reconciliation" course.

Best regards and good luck with your Odoo training!
