A client has created an estimate in QuickBooks Online Plus. They've selected a Copy to purchase order. Why might a certain product/service item from the estimate not appear on that purchase order?
a) The product/service item doesn't have "I purchase this product/service from a vendor" checked
b) Purchase orders are non-posting
c) The estimate hasn't been turned into an invoice yet
d) Estimates are non-posting
e) The estimate is dated in the future, and the purchase order is dated today
