Why is the plugin not considered for sales?

Hello Mehdi,

Thanks for reaching out. We’re sorry you are having problems.

Please make sure you’re running the most recent version of the plugin, 2.5.5.

Then navigate to WooCommerce > Settings > Cost of Goods > Advanced and enable Force costs update options and then go to the Tools & Reports section and enable Order tools > Recalculate orders cost and profit and save changes.

Please let me know if you continue to experience problems.
