How do you get the finish goods inventory?

Finish Good Inventory is just a term that means the inventory you builit(manufactured), or the inventory you have to sell that is ready to go out the door. You get it buy assembling pieces to make your product.

Very vague question. You're not asking if you need beginning inventory, ending inventory or what is going to go INTO that inventory.

In real life you're gathering your costs in WIP, and then keep track of what has gotten finished, taking those costs and moving them out of there and into Finished Goods. The costs move back out when something is sold.

But... I'm making a guess this is from homework. In which case, it all depends on what type of information you've been given and what the problem is up to. There isn't really any one answer to it.
