Is anyone able to walk me through the building of an inventory item from start to finish? I'm confused on how to use the program for this... I have a single product, we have multiple things that went into creating this product. I want to be able to track or know how much a single unit of this product cost us to make, considering there is a cost to manufacture, label and ship the product to us. From reading on the knowledgebase, I think I would use the "build from assembly" icon, but it makes no sense to me. If I have a purchase invoice FOR a component of the product, how do I link it to that product to know that was a cost of making the product?
