Net Sales by Postal Code
In the drop down I have selected to show all sales for April. The Total Net Sales is ALL of their sales for the month. The NET SALES in the list is the total number of sales of the checks that have a customer applied to the check (events, etc.) I have highlighted in Pink, the FILTERED NET SALES.
// If a check is NOT assigned to a customer, or that customer doesn't have a postal code in their account then those sales will not reflect on the report.
