[NSFW] POS doesnt pick Cost of goods

I have a fied to register cost ( using a plugin (pro) ) to manage my product cost, margins, etc, and using POS I see It always 0€ the cost so my orders are always 100% profit.

Do you have any solution for this? by the way, I cannot use your plugin Cost of goods, because i′m already using another plugin, premium version, so I need to know how to record the product cost in new orders using POS

THanks
