Amount Due

Amount due (also called 'balance due', 'due amount', or 'payment payable') is the figure a customer is obligated to pay. It usually appears as the last and most prominent line on an invoice, after the subtotal, taxes, discounts, partial payments, and any credit notes have been applied. When an invoice is brand new the amount due equals the total; once a partial payment is recorded the amount due drops to the unpaid remainder. Sellers should make the amount due unambiguous — currency symbol included — so the buyer never has to recalculate it.
