The two principal methods of payment for exported goods are by bill of Exchange and by letter of credit. the bill of exchange is an order in writing requesting someone (the buyer) to pay a specified sum of moeny at a specified date.
if the bill must be paid immediately, it is known as a sight Bill. The drawer ( Exporter) draws up the bill of Exchange， naming the person who must pay the bill.
This person (the buyer) is known as the drawee. The drawer (the exporter) then gives the Bill of Exchange to the bank,
When the bank presents the bill to the drawee (the Buyer) he must either pay it immediately (if it is a Sight Bill) or accept if by writing " Accepted" on it.
当银行向付款人（买方）提示汇票时，他必须立即支付（如果是即期汇票），或者如果以书面形式在汇票上承诺“接受 “ 。
By accepting a bill, a person agree to pay the bill at a specified date (usually in three months),
When the drawee pays or accepts the bill. the bank gives him the documents which allow him to collect the goods from the quay when they arrive.
Receiving the documents when the Sight Bill is paid is called " Documets against Payment D/P" Receiving the documents when a bill is accepted is called "Documents against Acceptace D/A".
当即期汇票支付后收到运输单据，这称为“付款交单-D / P”。当承兑汇票后收到运输单据称为“承兑交单-D / A”。
The main document in exporting is the Bill of Lading,which is the title deed to the goods, The title deed is the document (deed) which proves ownership of the goods.
When a Bill of Exchange has been accepted by the drawee it becomes negotiable. This means that is can be transferred to another person, to pay a debt for example.
On the other hand, if the exporter does not want to wait for payment of an accepted Bill of Exchange. he can discount (sell) it at a Discount House. Discounting Bills of Exchange is a way of lending and borrowing money.
另一方面，如果出口商不想等待承兑汇票的支付。 他可以在贴现行贴现（卖出）。 贴现票据是一种贷款和借款的方式。
A Bill of Lading is also negotiable so goods can be sold by selling the Bill of Lading before the goods actually arrive in the importing country.
A letter of credit is a letter written by the buyer's bank to the exporter's bank authorizing payment of a specified sum of money to a specified person ( the exporter).
The importer has to apply to his bank to open a letter of credit. The exporter is paid when the presents the export documents to his bank.
