Walmart Fulfillment Services, or WFS, is Walmart's version of Amazon FBA: you send inventory to Walmart, and Walmart ships your orders. It can make your listings more competitive, but the fees and storage rules decide whether it pays off for each product.
How WFS works
You ship inventory to Walmart's fulfillment centers. When a customer orders, Walmart picks, packs and ships the item, and handles customer service and returns for that order. You still control your listings and prices.
What WFS costs
Fulfillment fee. A per-unit fee based on the item's shipping weight, with additions for some product types. Walmart publishes the full table in its WFS fee guide.
Storage. Billed monthly by volume. From January to September it is $0.75 per cubic foot per month. From October to December, items stored longer than 30 days pay an extra $1.50 per cubic foot per month. Since June 30, 2026, inventory stored 366 to 450 days costs $2.25 per cubic foot per month, and more than 450 days costs $7.50.
To work out cubic feet, multiply length, width and height in inches and divide by 1,728. A 12 by 6 by 6 inch box is 0.25 cubic feet, so it costs about 19 cents a month to store outside peak season.
On top of WFS fees you still pay Walmart's referral fee on every sale. Put your numbers into our free Walmart profit calculator and switch it to WFS to see your profit per unit.
What you get
WFS orders can carry fast-delivery promises such as two-day shipping, which help your listings convert and count toward Walmart's Pro Seller badge. You also hand off packing, shipping and most customer questions, which frees up time if you are growing quickly.
What can go into WFS
You need an approved Walmart Marketplace seller account. Items can weigh up to 500 pounds including packaging, and must meet Walmart's prep, labeling and product-safety requirements. Some product types, such as certain hazardous materials, are restricted, so check eligibility for each item in Seller Center.
How to get started
In Seller Center, turn on WFS, choose which items to convert, and create an inbound order. Walmart tells you where to ship. Prep and label your units to WFS standards, send the shipment and track it until it is received. Start with a few of your best sellers before moving more of your catalog.
When WFS pays off, and when it doesn't
Good fit: small and medium items that sell steadily, products where fast delivery helps you win the sale, and sellers who want to spend less time packing and answering shipping questions.
Poor fit: slow movers that will sit for months, low-priced items where the fulfillment fee eats the margin, and very large or heavy products that cost more to store and ship.
Many sellers do both: WFS for their fastest sellers, and their own warehouse or 3PL for the rest. Watch storage age closely, because inventory older than a year now costs several times the normal rate.

Questions sellers ask
Does WFS handle customer service and returns?
Yes. For orders fulfilled by WFS, Walmart handles customer service and returns.
How are WFS storage fees calculated?
By volume: length times width times height in inches, divided by 1,728, times the monthly rate. Rates rise for items stored more than 30 days in October to December and for inventory older than a year.
Do I need WFS to get fast-shipping badges?
No, but it is the simplest way. You can earn fast-shipping tags with your own fulfillment if you consistently meet Walmart's shipping-speed standards.
