How to use warehouse and inventory for Showing inventory balance?

Hi, all
Please help me , to use warehouse and inventory for showing inventory balance
i try to purchase product to inventory but when i sell out , it not show balance
Ex: i buy beer 10 bottle to stock and sell to customer 4 bottle = balance is 6 bottle

  1. add new inventory item

  2. add Transaction

  3. add Receipes

  4. sell Beer Lao to customer 4 Bottle

  5. i check warehouse and Report it’s not show balance

  6. Show on the Report

You entered 10 bottles in your recipe so selling 4 items decreases 40 bottles. As you already purchased 10 bottles -30 bottles remains.
