Yes, many ecommerce platforms allow you to push your products from your online store to Amazon and vice versa. This is called multichannel selling, where you sell both on your own website as well as on a marketplace like Amazon. BigCommerce, for example, integrates with Amazon Marketplace. This lets merchants tap into Amazon’s huge selling potential by letting you list your products on Amazon straight from your BigCommerce control panel, using centralized inventory and order processing and fulfillment.
