使用 Avalara AvaTax 的注意事项
在安装 Avalara AvaTax 并将其连接到 Shopify 之前，请查看以下注意事项。
Avalara AvaTax 应用支持收取 VAT，但不支持 VAT 免除。Avalara 无法收集免税报告和退税所需的 VAT ID。
如果您在 Shopify 中发放退款但未同时选择商品或重新入库数量，则 Avalara AvaTax 不会创建退货文档。
Avalara AvaTax 中不会报告部分退款。如果您发放部分退款，则必须手动调整报告。
某些第三方服务会向 Avalara 提供报告，例如 eBay，而某些其他服务则不会，例如 Amazon 或 Facebook。第三方服务的报告可能导致 Avalara AvaTax 中的订单信息重复。如果您有向 Avalara AvaTax 报告订单的服务，您可以更改设置，以防止 Shopify 也报告这些订单。在 Shopify 后台中，转到设置 > 税费和关税，打开 Avalara AvaTax 设置，然后取消选中将文档发送至 AvaTax。
Avalara 仅在 Shopify 结账流程中运行，并且不适用于替代此结账流程的应用。这包括 Facebook 渠道应用。
支付网关处于测试模式时所下的订单由 Avalara AvaTax 计算，但不会提交到 Avalara，也不会在其中显示。

Considerations for using Avalara AvaTax
Before you install and connect Avalara AvaTax to Shopify, review the following considerations.
The Avalara AvaTax app supports collecting VAT, but it does not support VAT exemptions. Avalara can't collect VAT IDs, which are required for exemption reporting and returns.
If you issue a refund in Shopify without also selecting an item or restock quantity, then Avalara AvaTax doesn't create return documents.
Partial refunds are not reported in Avalara AvaTax. If you issue a partial refund, then reporting must be adjusted manually.
Some third-party services report to Avalara, such as eBay, while others do not, such as Amazon or Facebook. Reporting from a third-party service might result in duplicate order information in Avalara AvaTax. If you have a service that reports orders to Avalara AvaTax, then you can change your settings to prevent Shopify from also reporting those orders. In your Shopify admin, go to Settings > Taxes and duties, open your Avalara AvaTax settings, and uncheck Send documents to AvaTax.
Avalara functions only in the Shopify checkout, and will not work with apps that replace the checkout. This includes the Facebook channel app.
Orders made while your payment gateway is in test mode are calculated by Avalara AvaTax, but aren't committed to Avalara and don't appear there.
Install and connect Avalara AvaTax
If you have an Avalara Sandbox account, also known as a development account or a test account, then you can use it to connect to the AvaTax app.

Use an existing Avalara account.
Create a new Avalara account, and then connect the AvaTax app to your Shopify admin.
