YITH WooCommerce Multi Vendor (Premium Plugin):

If you have e-commerce you might consider the possibility to make it a multi-vendor shop. Owners of multiple product vendor websites have a huge advantage of getting passive earnings. Because they earn a commission on each sale.
Consider, the more vendors on your websites, the more sales, the more you can earn without lifting a finger. Your website will receive more traffic if there are more vendors on your website.

It’s like a virtuous circle, vendors take traffic and sales, your site becomes stronger and it gets a better and better positioning, then more and more vendors are interested in selling in your platform and in benefiting from endlessly increasing traffic. And it’s all easy earning for you!ul
