Customer/Supplier Reference: often a line item reference for the customer/supplier from their PO/SO

Quantity Ordered per Each/Container/Container Type: self-explanatory
Amount per Unit: price/cost
Estimated Quantity: when the actual quantity sold is unknown (like when selling containers by the ton) this provides an estimate.
