Many people want to know the difference between WIP and Semi- finished goods.
A semi finished good is wort, green beer, dry hopped beer etc. after it has been completed. In other words the semi finished good you receive into inventory when you do a receipt from production.
A WIP item is when the materials have been released to produce wort, green beer, etc. but you have not yet completed the production process and received the item into inventory.
You should not be putting any balances into these accounts when inputting your opening balances; other then the ones that automatically get posted when doing your WIP Goods Receipt.
