Difference between billed and invoiced amounts in the dashboard

In the Dashboard page, you will see the Billed and Invoiced amounts on Trend section and Overview section

Billed Amount follows the date of the Tasks while the Invoiced amount follows the date of the Invoice and takes into account the Invoice discount applied.
