Concept Definition    (B4X)

   Invoice (1) "an itemized bill for goods sold or services provided, containing individual 
   prices, the total charge, and the terms."    (B5L)
   This suggests that the goods or services were already provided.  Is this
    invariably true for the charges in an "Invoice"?    (B5M)
