Every seller now has a powerful new marketplace to integrate with.

I would say this marketplace is a must-have to expand your reach and sales.

What is this powerful new marketplace we speak of?

Walmart! Yes, that’s right.  Walmart is the NUMBER 4 eCommerce site in the United States.

Marketplace selling has dominated the Internet since the early days of the world wide web, with Net Market and the Shopping Network, but it’s made big changes since then and e-commerce now accounts for 7.80% of all retail sales in the United States. Those sales are primarily happening on third party online marketplaces, the largest of which are Amazon, eBay, Newegg, Etsy, Sears, and several others.

But, while many of us could easily name those and other e-commerce giants, many might be surprised to learn that Walmart is among the top in the category. In fact, Walmart is now the second largest third party marketplace in the USA by visitors (about 88 million per month), and the third largest by sales.

Quick History of Walmart Marketplace

Walmart initially opened their third-party marketplace to just a few large-scale retailers, bringing eBags, CSN Stores, and Pro Team on board in 2009, before opening up to more sellers and allowing for wider marketplace applications in 2015. By May of 2016, Walmart's list of third party sellers had grown to over 500. It’s also set to keep growing, as Walmart aims to aggressively expand and grow their marketplace by over 1 million new items per month. And, in early July 2016, Walmart completed an overhaul of their backend system and launched a new and easier to use access portal for retailers.


Walmart has taken steps make setting up and integrating your products easier, which is very appealing to the large retailers that Walmart wants to attract. Kind of reminds us of Amazon Seller Central’s interface, maybe even prettier!

Combined with the fact that products are listed side-by-side with Walmart products, this presents a massive opportunity for our Extensiv sellers.

Anyone can apply to the Walmart Marketplace to become a seller on their  platform, providing you pass the rigorous application process.

Walmart Checklist

Here are Walmart Marketplace KPIs and metrics that you should be thinking about during your Walmart Marketplace seller application process:

  • What’s your seller order defect rate on Amazon (Make sure your Amazon order defect rate is less than 1% - this is a leading indicator)
  • What’s your seller feedback ratings across marketplaces (Make sure you have high Amazon and Ebay feedback ratings and have an explanation prepared for any low Amazon or Ebay seller feedback ratings.
  • What’s does your SKU distribution and catalog look like - are you the brand or a reseller? Walmart’s looking for a category leaders and brand owners and experts.
  • Are your company item’s fresh, new and hot on the e-commerce market or are they sunsetted and end of life?
  • Are you able to meet consumer demands and constantly have your product available and in-stock? Do you have over-selling prevention mechanisms in place to provide a superior customer experience to the Walmart consumer?
  • How often are you winning the Amazon Buy Box? Do you have 20% buybox share, 60% share or do you not compete with anyone in the Buy Box and control price across all the places you sell
  • How competitive are you on price if you do share the buybox with other Amazon sellers? Consumers are shopping on Walmart and need to know that their price is the lowest and they don’t need to look elsewhere.
  • What’s your customer support like? Who handles the customer support and what’s your Amazon seller feedback rating for the last 30-days?
  • Lastly, what is the return policy? Do you offer the same or better service than Amazon? How will you translate your return policy to selling on Walmart?

Where formerly, the Walmart Marketplace platform was only open to marketplace listing tools that take a percentage of profits, you can now get started with the Amazon Marketplace using Extensiv Order Manager!

Integrating Extensiv with Walmart

Walmart maintains strict quality requirements for all sellers on their platform. In addition, Walmart e-commerce retailers are in charge of their own order fulfillment, and while you can set your fulfilment times and cut-off times for processing during the day in the Partner Portal, it is crucial that you meet the deadlines you set. Here, Extensiv can help.
