After plugin activation strings with the cost of goods in the order, profit, and the margin (percentage of profit relative to prime cost) appear in the backend in the description of the order. Profit is calculated without delivery cost, but with discounts.
If the purchase price is not set for all products in the order, a warning is displayed listing the articles and names of the corresponding products. The text of all labels displayed can be changed in the plugin settings.
The output of information on cost and profit works independently.
