What Is Walmart WFS? A Setup Guide for Sellers

If you sell on Amazon with FBA, you already understand the model: ship your inventory to the marketplace, let them store, pack, and ship every order, and get a trust badge that lifts conversions. Here's what surprises most Amazon sellers — Walmart has the exact same thing, and barely anyone is using it. It's called Walmart Fulfillment Services (WFS), and if you're not on it, you're leaving an entire sales channel on the table. This guide covers what WFS is, how it stacks up against FBA on cost, and a step-by-step walkthrough of converting and shipping your first inventory.

What Is Walmart WFS?

Walmart Fulfillment Services is Walmart's in-house program for storing and shipping third-party seller inventory — the direct counterpart to Fulfilled by Amazon. You send your products to Walmart's warehouses, and when an order comes in on Walmart.com, Walmart picks it, packs it, and ships it to the customer, fast. The listing carries a "Fulfilled by Walmart" badge, which signals the same trust and delivery speed a Walmart+ shopper expects.

Crucially, WFS isn't just shipping. Walmart also handles customer service and returns for WFS orders, and there are no setup, monthly, or hidden fees to enroll — you only pay for fulfillment and storage. Qualifying items display a 2-day shipping tag, the visibility signal that moves the needle on Walmart.com.

The opportunity is real because the platform is growing fast. Walmart's marketplace has crossed 150,000+ active sellers and its GMV has been climbing more than 30% year over year, yet a huge share of Amazon-first brands still haven't touched it. If you're already established on Amazon, WFS is one of the cleanest ways to expand your brand to Walmart without rebuilding your whole operation — most sellers see Walmart add somewhere in the range of 5–10% of their Amazon revenue, sometimes more.

WFS vs. Amazon FBA: How the Costs Compare

The two programs work almost identically, but on fees there are five differences worth knowing — and most of them favor Walmart.

1. Fulfillment fees are lower past a pound. On tiny items under 4 ounces, Amazon holds a slight edge (around $3.06 vs. $3.45 per unit). But as weight climbs toward and past one pound, WFS pulls ahead — on average it runs about 15% cheaper than FBA, and Walmart's weight-based rate card is simpler and more predictable.

2. Storage is the big one — especially in Q4. Walmart charges a flat $0.75 per cubic foot year-round. Amazon sits close to that for most of the year (~$0.78), but during peak season (October–December) FBA storage rockets to roughly $2.40 per cubic foot. WFS has no peak surcharge — the savings during the most important selling quarter are substantial.

3. No inbound placement fees. Amazon has made inbounding painful: inbound placement fees, split shipments across multiple fulfillment centers, and the rules around identical-box shipments. Walmart skips all of it — you set up one shipment, print labels, and send it to a single destination. That alone removes a real operational headache.

4. Multi-channel fulfillment (MCF) now works. Until late 2024, WFS couldn't fulfill orders from outside Walmart. Now it can — so you can store inventory in Walmart's warehouses and have it ship your Shopify, eBay, or Etsy orders too, just like Amazon MCF.

5. The trust badge lifts conversions. Whichever marketplace you're on, a platform-fulfilled badge converts better than seller-fulfilled. Walmart has reported conversion-rate increases of over 30% on WFS items versus seller-fulfilled ones — shoppers trust the delivery promise.

Fees reflect recent rate cards and Walmart has been running new-seller incentives in 2026 — always confirm against the current WFS and FBA rate cards before you model margins.

How to Set Up WFS: A Step-by-Step Walkthrough

Here's the full process using a real example. We manage Walmart for Nuts on the Run, a powdered-peanut-butter brand whose SKUs had been seller-fulfilled — shipped from the brand's warehouse or a 3PL. Here's exactly how we move one of their SKUs onto WFS.

Before you begin: get approved for WFS

One step the screen-share tutorials skip: you have to apply for WFS first. In Seller Center, find the WFS application link near the bottom of the left-hand navigation. Walmart reviews a few business details before approving you:

• Last year's total revenue
• Your SKU count and the percentage that are new products
• Average selling price of the SKUs you plan to run through WFS
• Which brands you'll sell, and whether you're the brand owner, an authorized seller, or a reseller

Walmart recommends starting with at least 50 items and replenishing continuously to see the full GMV benefit. Once you're approved, the hands-on flow below is four steps.

Step 1: Convert the listing to WFS

In Seller Center, open your catalog and find the SKU you want to convert (for Nuts on the Run, we started with the crunchy powdered peanut butter). This is the same move as converting an Amazon listing from FBM to FBA. Click the three dots next to the item and choose "Fulfill with WFS." A new tab opens with most of the product info pre-populated, but Walmart's supply chain requires a few fields you'll need to fill in:

• GTINs: the product GTIN, the each GTIN, and the orderable GTIN. If you're selling a single retail unit, the orderable GTIN is the same as the each GTIN.
• Dimensions and weight: length, width, height, and unit weight. If you don't have them handy, pull the dimensions from a similar-sized product in your catalog.
• Required attributes: selling price, country of origin (e.g., United States), and any category-specific fields — food items, for instance, require certain details.
• Inner-pack and case GTINs are optional unless you sell in case packs.

Hit Submit. If anything's missing, Walmart flags it with an error; otherwise you'll see "item successfully submitted."

Step 2: Wait for the conversion to process

Head to the activity feed. Your conversion shows up under the WFS convert fee type and moves from pending → processed. This usually takes 10–15 minutes (sometimes faster). Until it's processed and you've actually shipped units in, the SKU won't appear under your WFS inventory — converting a listing isn't the same as having stock in the warehouse.

Step 3: Create an inbound shipment

Once converted, choose Send inventory and search for your SKU to add it to an order. Set your expected ship date and ship-from location, then tell Walmart how you're packing it. Walmart does the math for you: if you say there are 18 units per case and a total of 18 units, that's one master case; bump the total to 36 and it becomes two cases. Set this up as case-packed (rather than individual units) when you're sending full cases, then click Create to generate the inbound shipment — Walmart calls this a shipping plan (your items, their distribution, and the carrier).

Step 4: Set up the shipment and ship it

Click Set up on the shipment. Confirm the destination and your case/unit counts, enter your master-carton dimensions and weight, and choose small parcel or LTL. Walmart calculates a rate — by default it uses FedEx (Amazon uses UPS), and the rates are competitive. Accept the charges, then print your box/barcode labels and carrier labels, apply them to your boxes, and hand off to the carrier.

Is WFS Right for Your Brand?

If you're already strong on Amazon and haven't moved on Walmart, WFS is one of the highest-leverage things you can do to diversify. You get faster delivery, the trust badge, lower peak-season storage, and no inbound-placement headaches — and you stop keeping all your eggs in one marketplace basket. It won't replace Amazon, but adding 5–10% of your Amazon revenue from a second channel, with margins that are often friendlier, is a strong return for a setup process that takes minutes per SKU. If you want a hand standing it up — or want to pair it with ads — our Walmart marketing services cover both, and our guide to the fastest way to grow Walmart Marketplace sales shows where WFS fits in the bigger picture.

Walmart WFS FAQs

What is Walmart WFS?

Walmart Fulfillment Services (WFS) is Walmart's in-house fulfillment program — the equivalent of Amazon FBA. You send inventory to Walmart's warehouses and Walmart stores, picks, packs, and ships orders to customers, with a "Fulfilled by Walmart" badge on the listing.

Is Walmart WFS cheaper than Amazon FBA?

For most products at or above one pound, yes — WFS averages about 15% cheaper. Walmart also charges a flat $0.75 per cubic foot of storage year-round, while Amazon's peak storage (October–December) jumps to roughly $2.40 per cubic foot. Amazon keeps a small edge on very light items under 4 ounces.

How long does it take Walmart to receive WFS inventory?

Converting a listing to WFS usually processes within 10–15 minutes. After you ship a created inbound shipment, Walmart's warehouses typically receive and make inventory sellable within a few days — often within 24 hours of arrival.

Can I use WFS to fulfill orders from Shopify or eBay?

Yes. As of late 2024, WFS supports multi-channel fulfillment (MCF), so Walmart can ship orders from your Shopify, eBay, Etsy, and other channels using the inventory you store in its warehouses.

Do I need WFS to sell on Walmart Marketplace?

No — you can fulfill Walmart orders yourself or via a 3PL. But WFS earns the "Fulfilled by Walmart" badge, faster delivery, and a meaningful conversion lift, so it's the recommended path for most serious sellers. It also feeds your Walmart search ranking, since fast, reliable fulfillment supports visibility.

What are the requirements to use WFS?

You apply through Seller Center, and Walmart reviews your annual revenue, SKU count and share of new products, average selling price, and the brands you sell (and whether you're the owner, an authorized seller, or a reseller). Walmart recommends starting with at least 50 items and replenishing consistently. There are no setup or monthly fees to enroll.

Does WFS handle returns and customer service?

Yes. For WFS orders, Walmart manages pick, pack, ship, customer service, and returns — the same hands-off model as Amazon FBA.

---

The bottom line: Walmart WFS is FBA's lesser-known twin — same model, often lower fees, no peak-season storage spike, no inbound-placement maze, and a conversion-lifting trust badge. If you sell on Amazon and haven't set up WFS, you're skipping a fast, profitable second channel. Convert a SKU, ship a case in, and see what Walmart does with it.
