使用您的北美联合账户管理库存

在亚马逊美国、加拿大和墨西哥商城管理您的亚马逊库存时，了解卖家平台中全球 SKU 和商城特定的 SKU 的区别非常重要。

全球 SKU

全球 SKU 使用美国、加拿大以及墨西哥之间的共享库存存储。当您在卖家平台创建报价时，您可以选择“【现有报价】”来创建一个全球 SKU。使用全球 SKU 时，总库存量适用于全部商城。例如，如果您有 100 件库存商品，将会显示在美国有 100 件商品，在加拿大有 100 件商品以及在墨西哥有 100 件商品。这个“100”适用于这三个国家/地区，【而不是】合计为 300 个商品。如果一件商品在加拿大售出，那么所有商城都会显示剩余 99 件商品。

注意： 定价在两个商城内分别管理。

【如果您自行配送订单】，您应该使用全球 SKU 管理美国、加拿大和/或墨西哥的库存。亚马逊物流库存无法作为全球 SKU 发布。注意，如果您将一个全球 SKU 从卖家配送更改为亚马逊配送，则此更改会影响每个商城中的该 SKU。

【如果您是从美国配送到墨西哥，请在选择运输承运人时考虑以下因素：】并非所有配送选项都可以提供全球亚马逊买家所期待的运输速度。例如，最近一项针对由卖家从美国配送至墨西哥的订单的调查显示，约有 69% 通过美国邮政署 (USPS) 配送（在墨西哥境内使用的是墨西哥邮政 (SEPOMEX)）的订单未达到亚马逊的国际配送运输时间要求。为了向美国发往墨西哥的货件提供一流的买家体验，我们强烈建议您使用其他承运人（例如 FedEX、DHL、UPS）。

商城特定的 SKU

商城特定的 SKU 作为商城级别的库存存储进行管理，这意味着您将在美国、加拿大和墨西哥管理不同的库存存储。当您在卖家平台创报价时，您可以通过选择【唯一报价】来创建一个商城专有 SKU。商品的库存和定价将在两个商城中分别管理。

注意： 如果您想在多个商城上发布商品，但您希望在某个情形下自行配送，而在另一个情形下由亚马逊配送，则您需要为卖家自行配送的商品和亚马逊配送的商品创建单独的 SKU。

【如果您使用的是亚马逊物流】，可以使用商城特定的 SKU，并在美国、加拿大和墨西哥亚马逊运营中心内作为单独的存储来管理您的库存。请注意，进入美国运营中心的库存应该从您的北美联合账户的 Amazon.com 部分部分配送，反过来对于加拿大和墨西哥也是如此。例如，如果您在加拿大商城有亚马逊物流商品，您的 ［ 发货地址 ］ 必须是加拿大。

注意： 在北美联合账户使用库存文件时，为可售库存商品数量上传一个值十分关键。如果数量栏是空白的，系统会将数量视作“0”，原来的商品信息就会显示为“0”个在售商品。

Sell on Amazon's North America Marketplaces

With a North America Unified Account, you can conveniently switch in Seller Central between Amazon.com, Amazon.ca, and Amazon.com.mx seller tools to list products and manage orders in multiple marketplaces. You have the option to list in one, two, or all three of the available North American marketplaces.

The North America Unified Account allows you to more easily:

• Share listing information and manage your inventory consistently across Amazon's U.S., Canada, and Mexico marketplaces

• Keep track of orders on multiple North American sales channels in Manage Orders or with one combined Order Report

• Access tools and services to help you manage your business across the U.S., Canada, and Mexico marketplaces

• Pay a single monthly Professional selling plan subscription fee for your North America Unified Account*

• Update account information through a consolidated user interface

• Get paid to your local bank in your local currency thanks to the Amazon Currency Converter for Sellers

*Note: The single monthly Professional selling plan subscription fee is applied based on the Amazon marketplace to which you initially registered. For example, if you initially registered to sell on Amazon.com, your monthly subscription fee is listed on the Amazon.com Selling on Amazon Fee Schedule.

Managing Inventory in Your North America Unified Account

When managing your Amazon inventory across Amazon's United States, Canada, and Mexico marketplaces, it is important to understand the difference between the Global SKU and the marketplace-specific SKU in Seller Central.

Global SKU

A Global SKU uses a shared inventory pool between the United States, Canada, and/or Mexico. You can create a Global SKU by selecting "Existing Offer" when you go to create an offer in Seller Central. When using a Global SKU, the total amount of inventory applies to all marketplaces. For example, if you have 100 units of inventory, it will display that there are 100 units in United States, 100 units in Canada, and 100 units in Mexico. The 100 applies to all three countries and DOES NOT add up to a total of 300 units. If an item sells in Canada, then all marketplaces would show 99 units available.

Note: Pricing is managed separately in each marketplace.

If you are shipping an order yourself, you should use a Global SKU to manage inventory across the United States, Canada, and/or Mexico. Inventory fulfilled by Amazon is not eligible to list as a Global SKU. Note that if you change a Global SKU from seller-fulfilled to Amazon-fulfilled, this change will impact the SKU across every marketplace.

If you are shipping from the United States to Mexico, consider the following when choosing you shipping carrier: Not all shipping options deliver the transit speeds that Amazon customers worldwide have come to expect. For example, a recent study of orders fulfilled by sellers shipping from the United States to Mexico showed that approximately 69% of orders shipped via United States Postal Service (USPS), which uses Correos de México/Servicio Postal Mexicano (SEPOMEX) for delivery within Mexico, did not meet Amazon's international shipping transit time requirements. To provide a great customer experience on shipments from the United States to Mexico, we strongly recommend that you use other carriers (e.g., FedEx, DHL, UPS).

Marketplace-specific SKU

A marketplace-specific SKU is managed as a marketplace-level inventory pool, which means you will manage distinct pools of inventory across the United States, Canada, and Mexico. You can create a marketplace-specific SKU by selecting Unique Offer when you go to create an offer in Seller Central. The listing is managed separately in each marketplace for both inventory and pricing.

Note: If you want to list a product on more than one marketplace, but you want to fulfill it yourself in one case and fulfill by Amazon in another, you need to create separate SKUs for your seller-fulfilled and Amazon-fulfilled listings.

If you are using Fulfillment by Amazon, you can use a marketplace-specific SKU and manage your inventory in Amazon fulfillment centers in the United States, Canada, and Mexico as separate pools. Please note that inventory going to U.S. fulfillment centers should be shipped from the Amazon.com section of your North America Unified Account and vice versa for Canada and Mexico. For example, if you have a FBA listing on the Canada marketplace, your "Ships from" address must be in Canada.

Note: When using inventory files in the North America Unified Account, it is critical to upload a value for the quantity of available inventory units. If the quantity column is left blank, it will be read as "0" by the system and will change the original listing to display "0" available units.
