The Inventory Software calculates Gross Profit from the sales Cost - purchase Cost + Purchase Shipping Cost.
If the check "We pay shipping" is enabled then the Sales Shipping Cost will also be used in the Calculation.
There is an option available to limit the report for an Individual Sales Person which can be used to Calculate their commission.
There is also an option available to limit the Sales Gross Profit Report to display only the items that have been shipped
using a packing list created by the Software.
A date range is also available to limit the results.
