I use QBO and need to convert my raw materials inventory into finished goods inventory as I manufacture them. Each metal bar is purchased and then converted into 50 parts
You need QuickBooks Desktop Premier version (or Enterprise version) to convert raw materials into finished good inventory as you want. QBO is not designed for such a WIP process. So, I would waste my money paying for the 3rd-party app. It's expensive and will not work efficiently in most cases.
