Magento Marketplace is a SaaS solution that enables eCommerce stores to become online multi-vendor marketplaces. It allows multiple vendors to add products to a single website, with an inventory system that makes the store look more powerful. The platform enables vendors to manage a wide range of things by themselves, including products, sales, invoices, shipments, and credit memos using their Seller cPanel. The goal is to create an automatic online marketplace like Amazon or eBay, where sellers can take full control of their store.
