Lifetime sales on dashboard dude

I’m using a payment method of my country. When somebody realice an order in my website, and the payment is successfully, the order is changed to status complete.

The problem is, I can’t do “invoice”, and the lifetime sales statistics in the dashboard is not updated. (I guess it is because the invoice doesn’t exists in that order)

Exists an easy way to show the total for complete orders and not by invoices?

Thanks
