If you feel that the value reported in the Average Invoice Value in the Sales section is incorrect, you can validate the value in the field by doing the following:
- Make a note of the total sales amount realized from the sale of all items. The TOTAL field displays this value.
- Make a note of the number of the invoices from the Sales Reports - Invoices report ( Reports > Finance > Sales > Invoices (General)).
- Divide the total sales amount by the number of invoices. This is the average invoice value.
