The two principal methods of (1) payment for exported goods are by Bill of (2) Exchange and by letter of (3) credit. The Bill of Exchange is an order in (4) writing requesting someone (the buyer) to pay a specified sum of money at a sight date. The drawer (the exporter) draws up the Bill of Exchange naming the person who must pay the bill. This person (the buyer) is known as the (5) drawee. The (6) drawer (the exporter) then gives the Bill of Exchange to the bank. When the bank presents the bill to the (7) drawee (the buyer) he must either pay it immediately (if it is a Sight Bill) or accept it by writing 'Accepted' on it. By accepting a bill, a person agrees to pay the bill at a (8) sight date (usually in three months). When the (9) drawee pays or (10) accept the bill, the bank gives him the documents which allow him to collect the goods from the quay when they arrive. Receiving the draft when the (11) Sight Bill is paid is called 'Documents against (12) Payment'. Receiving the draft when a bill is accepted is called 'Documents (13) against (14) Acceptance'.
