我有 QuickBooks 2010 专业版，正如标题所示，我需要将产品和发票导入 Quickbooks。
一些背景...
我们是一家在线公司，我们在线销售产品，我的客户希望将所有产品导入到 quickbooks 中，并且每次在线销售也导入到 quickbooks 中，我们的网站是使用 ASP.NET 和 SQL Server 构建的。
我是快速书的新手，所以我不知道从这里做什么......
我听说过 IIF 导入和 SDK，遗憾的是我找不到关于它们的有价值的文档。谁能把我放在正确的方向（也许是一些示例代码）？请不要给我 quickbooks 网站的 SDK url。
谢谢
如果您不愿意查看 QuickBooks SDK，那么您就是在给自己带来极大的伤害。
实现您想要做的最简单的方法是通过 SDK 和 Web 连接器。我们的 wiki 上有 QuickBooks Web 连接器的基本概述。它专门用于将数据从在线网站移动到适用于 Windows 的 QuickBooks（就像您尝试做的那样）。基本思想是它会轮询您的网站，要求您做一些事情，并且您可以向它提供 XML 请求来做一些事情（添加客户、添加发票等）。
基本协议如下所示：
// Web 连接器要求您的 SOAP 服务进行身份验证 Web 连接器 => SOAP 服务器：使用用户名“xyz”和密码“bla”进行身份验证（身份验证）如果身份验证成功，则 SOAP 服务器返回一个票证值并继续该过程
// Web 连接器要求做一些事情 Web 连接器 => SOAP 服务器：嘿 SOAP 服务器，你有什么要我做的吗？(sendRequestXML) SOAP 服务器生成并返回一个 qbXML 请求
// Web 连接器将该请求中继到 QuickBooks，并从 QuickBooks Web 连接器接收响应 => QuickBooks：嘿 QuickBooks，SOAP 服务器给了我这个请求，你能处理它吗？QuickBooks 处理请求，并向 Web 连接器返回响应
// Web 连接器将来自 QuickBooks 的响应中继回 SOAP 服务器 Web 连接器 => SOAP 服务器：嘿 SOAP 服务器，这是来自 QuickBooks 的最后一个请求的响应 (receiveResponseXML) SOAP 服务器处理响应，处理任何错误并执行任何操作响应 SOAP 服务器返回完成百分比，如果小于 100%，则此过程继续...
// 该过程重新开始，Web 连接器向 SOAP 服务器请求下一个请求... Web 连接器 => SOAP 服务器：嘿 SOAP 服务器，您还有什么需要我做的吗？(sendRequestXML) SOAP 服务器生成并返回一个 qbXML 请求
... 等等等等 ...
如果您下载QuickBooks SDK（哎呀，对不起！），您会发现它包含一些您要求的内容。具体来说，它在此目录中放置了示例代码：
C:\Program Files (x86)\Intuit\IDN\QBSDK12.0\samples\qbdt\c-sharp\qbXML\WCWebService
