合同性质不同，合同报价方式也就不同。比如说，在国际货物买卖合同中，价格条款一般根据购买的货物，包括货物单价、数量以及贸易条款而确定，但在国际服务贸易合同中，价格条款一般只需要计价货币和合同总价。总而言之，常见的报价方式一般有三种，闭口合同报价、开口合同报价和闭口加开口合同报价。以下为一些国际贸易合同中的相关价格条款双语示例：

示例一：闭口合同报价（总价固定）

The Contract Price is five million, four hundred and thirty thousand American Dollars (US$ 5, 430,000). The Contract Price is an all-inclusive lump sum price for the GOODS as specified by BUYER. The all-inclusive lump sum price is the full payment to be made to the SELLER for supply of GOODS and Services, including all related works and furnishing of all the services required under the PURCHASE ORDER, including inter-alia, all manpower, and all costs associated therewith; MATERIALS and inclusive of duties (if any), taxes (Withholding Tax and VAT included), delivery, storage, protection, maintenance, handling and all other associated costs; consumbles and consumable materials, establishment charges; overheads and profit; WORK items and services required by the PURCHASE ORDER and not specifically itemised herein, are nevertheless included in the all-inclusive lump sum price and no payment over and above the all-inclusive lump sum price shall be made by the BUYER to the SELLER except where the SELLER specifically specified as extra items to be paid separately.

合同价款为五百四十三万美元。该价款是买方指定的货物的总价价款，也是支付给卖方交付货物并提供服务的全部款项，包括根据该采购订单要求所做的所有相关工作以及提供的所有服务，包括，除其他费用外，所有的人力和所有与此相关的开销；物资以及各种关税（如果有）、税收（包括预提税和增值税）、运输、储藏、保护、维修、搬运和所有其他相关的费用；易耗品和易耗材料收费；管理费和利润；本采购订单中列明的工作和服务以及本采购订单中没有列明的工作和服务，也包含在这个合同总价值中。除了买方单独指出这是额外的工作项目应单独支付外，买方不会向卖方支付任何超过本合同总价的款项。

示例二：开口合同报价（总价不固定）

If the Client has any questions regarding the invoice,the Client shall immediately notify the Counsel of such questions in writing.The Client shall not unreasonably withhold payment of the Counsel's invoices.

律师应向客户提供发票，发票应包括律师在提供服务时产生的各种费用 和开支以及增值税。律师应向客户提供计算机打印出来的为完成客户任务所花时间（如果可能，将每小时分成10等份）以及发票回执（Act of Transfer and Acceptance）。对于没有争议的发票，客户应在收到后10个日历日内支付。如果客户对发票存疑，应立即书面通知律师。对于律师提供的发票，客户不得无故拒绝支付。
