Client Billing has a new Detailed Charges Report to outline where specific charges are being applied to customers. This allows you to support your billing with detailed reporting of a wide variety of charge information. The report can detail hours of storage charges applied, additive charges applied for specific additives and more general charges for services, operations and stock usage.
This report can be accessed under Winery Reports -> Client billing.
It comes in both a pdf and xls spreadsheet. Below is an example of the PDF.
