Firearm inventory and Cost of good sold

[akatonyt]

I have a firearms business.

BOY inventory equals previous years EOY inventory.
Now, current year EOY inventory is what I have left on hand to sell.

On the next page, What is the "Cost of purchases" referring to? ie: EOY inventory lets say is $8000. Is the " Cost of Purchase" $8000 since that is the value/cost of the leftover inventory? Or is it "$0" since the cost doesn't directly relate to production or resale? Or something else entirely?

Cost of purchases would refer to purchases you made during the year that added to your inventory until the goods were sold.
