You can send a statement to your billing customer in two ways.

If you would like to send a statement for multiple outstanding invoices across a number of jobs, select your billing customer from the customer list or use search. 

Up in the top left corner you can choose to view, email or print a Summary of Activity for all of the invoices that are currently due:

If you want to send a statement for a particular job where you have sent out one or more invoices, click ⋮ options beside the Create Invoice button:

Please note that there is no way to filter date for Summary of Activity.

At this stage, it can only show them all outstanding invoices and any paid invoices from the last two months from the day it is viewed or extracted.
