If some of your customers would like a consolidated summary invoice report, the "Sales Invoice/Credit Details" report will show a breakdown of all invoices (itemized with shipping charges) per location for the customer and month specified in the criteria tab.
Please go to Reporting>Reports and choose the ‘custom’ and ‘report’ options at the top and it is called Sales Invoice/Credit Details. In the criteria tab, select the customer and this month/last month and you can email it from here. You can also create several copies of this as individual customer reports in the report designer in the management reports section. Then you will be able to set the customer and dates and save in PrimaClient so that you can then schedule the auto email email report too (see link below).
