In documentary collection, the exporter sends the draft and the shipping documents representing title to the goods to his bank, which forwards them to another bank in the importer’s country, which in turn contacts the customer. In the case of D/P, the documents will not be released to the importer until payment is effected. In the case of D/A, documents are handed over to the importer upon his acceptance of the draft drawn by the exporter.
在跟单托收中，出口商将汇票以及代表货物所有权的装运单据交寄给银行，该银行将汇票和单据转给进口商所在国的另外一家银行，这家银行再联系客户。在付款交单的情况下，只有当货款付清后，才把装运单据交给进口商。在承兑交单的情况下，进口商在承兑了出口商所开出的汇票后，便可得到单据。
