Accounting for inventory/stock held

[Chris Serella]

I'm wondering if I need to account for my inventory/stock pre and post 
manufacture?

I buy in a bunch of ingredients from various suppliers which I put into 
expenses:supplies (Should this be an asset?)

once manufacturing is complete I now have stock to sell: Do I complete a 
transfer of the cost price to Assets or do they remain in Expenses?

Kind Regards,
