This report behaves exactly the same as the Top Customer Sales report ( http://www.openvpms.org/customisation/top-customer-sales-report) in that it allows you to select a defined number of the top customers by sales for a specified data range.  

This report has been modified to be suitable for export and therefore can be used for mail merging.  It includes separate name, address, email fields as well as fields for total sales and visits for the customers selected.

Cheers
