+=================================
+Print Customer Activity Statement
+=================================
+
+The activity statement provides details of all activity on the customer receivables
+between two selected dates. This includes all invoices, refunds and payments.
+Any outstanding balance dated prior to the chosen statement period will appear
+as a forward balance at the top of the statement. The list is displayed in chronological
+order and is split by currencies.
+
+Aging details can be shown in the report, expressed in aging buckets (30 days
+due, ...), so the customer can review how much is open, due or overdue.
+
+Configuration
