Walmart Fulfillment Services vs. Fulfillment By Amazon

Which is better for your ecommerce brand?

The two big retailers, Walmart and Amazon, are struggling to become the go-to place for online shopping and commerce.

When Amazon launched its Fulfillment Service by Amazon (FBA) service in 2006, it changed the game for all sellers with this new model, making it the only ecommerce platform that offered a program like this. However, in February of 2020, Walmart launched its own version of FBA—Walmart Fulfillment Services. WFS has a lot of similarities with FBA, offering sellers access to its warehousing and delivery infrastructure.

In this article, we'll review both fulfillment services and we’ll help you decide which service is more suitable for your business needs. In addition, we'll also look at Deliverr as a 3PL option.

Before 2020, selling on Walmart wasn’t an option for many sellers because the marketplace didn't offer logistics and warehousing services. However, the launch of WFS changed everything, and now there’s a competitive alternative to FBA but only for selected sellers.

Walmart is winking at its competitors with WFS, but there is a big important disadvantage in this service and it's that it only accepts shipments from within the US for now. So for now, Amazon’s FBA is still the one to beat.
