What is a Multi-Vendor eCommerce Marketplace?

We must understand single-vendor stores before understanding Multi-Vendor E-commerce Marketplaces.

For a Single Vendor e-commerce marketplace, think of it as a specific store. For example, if you want to buy a smartphone, you might go to the Samsung official website and buy the selected products. Or if you look at other vendors, you have to switch the website and reach another vendor.

In short, Single vendor e-commerce platforms are stand-alone stores selling products to multiple customers with a limited niche and product range.

For a Multi-Vendor E-commerce marketplace, think of it as a shopping mall where multiple vendors open their shops. Once the customers enter the mall, they have a wide range of options to choose from multiple vendors and multiple niches.

How does a Multi-Vendor Marketplace Work?

Multi-Seller eCommerce platforms follow a basic three-entity structure:

1. Marketplace Owner (Admin)
