My client has received many product purchases this year but had never entered the inventory into Quickbooks until April 24th. The purchases made in Jan-March (did not use POs) were recorded as an Expense. Should I correct that or just leave it in the expense account? I will be recording future purchases using POs moving forward. Also, What subaccounts should I have for COGS and Inventory Assets for recording Vendor discounts on the purchases (at the time of purchase) and shipping fees?
