The invoicing option source relevant data from each project and allows the Project Manager or Admin to bill the clients against the agreed terms. The billing can be done on hourly basis or based on a fixed amount. The invoicing option allows listing out open invoices/paid invoices, and sends reminders on a pre-scheduled basis. Options are available to customize invoices and send email invoices as well as print invoices.
