Inventory cost

I am in very simple business . i purchase good for 100 and sell it for 200 . it means 100 is Profit.

but in manager it shows very less.

  1. i dont want inventory cost. as i have “0” inventory cost.

In short i want to see the exact purchase and sale difference to see the pure profit as per above exaple. which involves no expense.

You purchased the item for 100 that is your expense. Suggest you read the guide regarding inventory first.
