Manufacturing stock items allows you to build a product from multiple components within your inventory, and then sell them as a single item with their own manufactured stock level.
Manufactured items can also be nested and used within other manufactured items.
Examples of this functionality would be muesli, sandwiches, packaged meals and more.
In its simplest terms, a manufactured item is an indirect item with its own stock level.
Before you can use manufacturing, you will need to create all the base item ingredients that are used in the manufactured items. These are the raw products with which you create your item.
