I have three types of stackable products.

1 - purchase only. in this category, I buy the product, store it in Raw material and use them for production.

2 - sales only. in this category, I use the ref 1 material as raw material and produce new products and sell the finished product.

2- Purchase, sale and manufacturing. in this type of product, the same product sometimes i purchase and sell directly to our customers and sometimes I produce/manufacture this product by using raw material ref 1.

I want to set up automated inventory valuation, please guide me on how i enter the account stock properties (valuation, input, output) and expenses account. 

 i have the following account  in the chart of account;

101-raw material inventory valuation -assets

102 - finish material inventory valuation - assets

103 - work in progress - assets

104 - stock receive - liability

105 - stock deliverable - Cost

106- the cost of goods sold

lets say i used  1) purchase only 

valution= 101 raw

input = 104 receive

output = 103 - WIP

FOR SALE ONLY 

i used

valuation=102 finish product 

input = 103 - wip

output = 106 COGS

expense = 106 cogs

what about produt 3) sale, purchase and manufecture 

valuation=?

input =?

output =?

expense =?
