What this screen is for
Revenue alone does not tell you which sales were worth making. This report sets each invoice's selling value against the cost of the goods on it and shows what remained.
When to use it
When a month's sales look healthy but the profit does not, this is where the answer usually is: a few large invoices sold at thin or negative margin. Reading it per bill shows which ones, rather than leaving you with a single blended figure.
