The key to succeeding on Walmart is to stop thinking about fulfillment as just a way to ship boxes and start seeing it as a growth lever. Michael Lebhar argued on The Smartest Amazon Seller that you have to be of Walmart, not just on Walmart. This means deeply integrating with their systems, and the most powerful way to do that is by using Walmart Fulfillment Services (WFS).
Lebhar’s point is that using WFS signals to Walmart that you are a serious and reliable partner. It’s not simply about meeting their required metrics for on-time delivery; it’s about aligning your business with Walmart
