Invoices -

概述

发票、账单是卖方在销售交易中向买方出具的商业单据,用于指明卖方已向买方提供的产品、数量和就产品或服务商定的价格。

发票模型经过训练,可以从各种类型的发票中提取关键数据点。该架构包含 27 个字段、7 个项目和一个货币分类器,用于提取有关客户、供应商、付款和产品/服务的信息,以及包括银行信息在内的付款详细信息。客户可以根据自己的要求调整字段架构。

特殊性

该模型会自动检测以下数据:

  • 供应商名称、供应商地址、账单名称、账单邮寄地址
  • 发票编号、采购订单编号、付款条款、到期日期
  • 净额、税额、折扣、总金额
  • 增值税号、增值税税率
  • 银行账号、银行名称、SWIFT、IBAN

Extracted fields

备注:

If you are using using public endpoints, such as https://du.uipath.com/ie/invoices, all fields are available. However, if you are using custom-trained extractors, the availability of extracted fields is dependant on the version you are currently using. You can also check the list of fields and types on any endpoint in the /info/model object. To access this, simply add /info/model to any endpoint, like so: https://du.uipath.com/ie/invoices/info/model. For an enhanced reading experience of the fields list, it's recommended to install a JSON viewer extension in your browser.

澳大利亚发票

The Out-of-the-box model for Invoices Australia has been deprecated because the Invoices model has been improved to support Australian invoices better than the Invoices Australia did previously. The ABN (Australia Business Number) and BSB (Bank State Branch) are recognized by the Vendor VAT Number and Bank Routing Number fields in the Invoices model.
