[Back](./) # I am unable to mark an invoice as sent in the finance module of Zoho Projects. What could be the reason? We currently do not have the option to mark an invoice as **Sent** in Zoho Projects. You can either send the e-mail from Zoho Projects or navigate to Zoho Books, where you can find the option **Mark as Sent** to mark the invoice as sent. * * *
