The Inventory Loader lets you do the following:
To use the page matching features of Inventory Loader, you must provide a product identifier and specific information about your offer. You can use a SKU and selected listing data when modifying existing listings.
Because Inventory Loader cannot be used to create new product detail pages, you do not need to provide detailed product data. A single Inventory Loader file can be used to upload or modify listings in multiple product categories at the same time.
Download the Inventory Loader to begin uploading your listings.
