• The module allows you to decide whether you want to consider the cost price of the product as it was at the time the order was placed, or whether you want to take the current value of the product's cost price. By default, the cost price is recorded at the time the order is placed, and this is used for the various calculations. If you prefer to use the current cost price, go to the module configuration and uncheck the corresponding option.
  
  
• Moreover, when the module retrieves the cost price value, it first looks at the level of the (default) supplier associated with the product (or product combination). If the cost price has been entered at this level, this value will be taken into account; otherwise, the module will look for the cost price value entered in the product's "Pricing" tab.
