Does the stock account balance show the profit & loss amount?

Question

When the goods are received from the vendors the postings are as follows :-
debit stock with the purchase price
credit vendors with the purchase price
However when a sales invoice is posted how will it decrease the stocks account? can someone tell me the postings for sales invoice? because if the postings for sales is going to be like this :-
credit stock with the sales price
debit customer with the sales price
then how can we calculate profit in the above situation? does it mean the net balance of the stock account will be the profit figure? because if the purchase price of the stock is 100 and the sales price is 150, then the stocks account will have a balance of 50 in the credit side in the above example.
does it mean the balance of stock account will be the profit amount?

Answer 1

Every material has a price in its master data. When goods are received, the system reads the value from material master and makes the entry as follows
Dr Stock Cr. GR/IR (later when invoice come, the vendor is credited, debiting GR/IR). (Any difference in PO price to the material master, will be posted to price difference account if you maintain Standard price)
The sales process happens in two stages: 1st the goods issue and 2nd billing. When goods are issued,
Dr.COGS
Cr. Inventory (with the same Material master price.)
At billing
Dr. Customer
Cr. Sales.
Stock account will only keep track of goods movement, how much came in and how many have gone out. This should not be considered to ascertain P&L. Should you need to find the P&L, you need to find the difference between the sales account and the Cost of goods sold account.
