Whether you’re selling clothing or hardware, home accessories or local services, there’s a lot you can learn from big e-commerce companies such as eBay, Amazon, or Etsy. These giants, which have amassed together in 2014 well over $120 billions in revenues, have all been small e-commerce websites once.

In a recent post on Entrepreneur, Wix.com founder and CEO Avishai Abrahami has highlighted three lessons that the super-successful e-commerce brands above can teach budding e-commerce businesses like yours. We liked Mr. Abrahami’s post so much that we felt we had to share the crux of it with you.

One of the key factors that led to eBay’s success is the real world sales structures and techniques it has used ever since its founding in 1995 to create a successful and sustainable online business model. eBay is also a great example of how to simplify shipping, make products easy to find in a large catalog, and effectively handle ecommerce inventory management for a huge catalog of products.
