Walmart Marketplace has grown from a closed, invite-only platform into one of the fastest-growing third-party marketplaces in the United States, and it now welcomes applications from sellers who can serve American shoppers. For sellers already running on Amazon, Shopify or eBay, it represents a large, lower-competition audience with no monthly subscription fee to get started. The trade-off is a tighter approval process and a marketplace that rewards competitive pricing and reliable delivery above almost everything else. This guide walks you through everything you need to start selling on Walmart Marketplace in 2026: how the application works, what it actually costs, how to choose between Walmart Fulfillment Services and shipping yourself, how to list products and win the Buy Box, and how to keep Walmart in sync once it becomes one channel among several.
Walmart Marketplace is the third-party selling platform on Walmart.com, where approved independent sellers list their products alongside Walmart’s own first-party inventory. A shopper browsing Walmart.com cannot always tell whether an item is sold by Walmart or by a marketplace seller, because everything lives inside the same catalogue, the same search results and the same checkout. Sellers manage their listings, orders and performance through Walmart Seller Center, the equivalent of Amazon’s Seller Central or Shopee’s Seller Centre.
The big draw is reach. Walmart.com attracts hundreds of millions of visits each month, and the marketplace side has historically had far fewer third-party sellers than Amazon, which means less competition for visibility on many product types. Because Walmart’s brand is built on everyday low prices, the shoppers who land there tend to be price-sensitive and ready to buy, which suits sellers with competitive cost structures.
Walmart Marketplace tends to be a strong fit if you:
Actionable Insight: Walmart Marketplace is not a beginner’s first storefront. The application favours sellers who already have ecommerce experience and clean fulfilment metrics. If you are completely new to selling online, it is usually easier to prove yourself on a lower-barrier channel first, then bring that history to your Walmart application.
It is less suited to brand-new sellers with no fulfilment history, to sellers who cannot serve US customers, or to anyone whose pricing cannot stay competitive, since Walmart’s pricing rules can quietly remove your products from the Buy Box or from search.
One of Walmart Marketplace’s most attractive features is its simple, success-based cost model. There is no setup fee, no monthly subscription fee and no per-listing fee. You only pay when you make a sale. This is a meaningful difference from Amazon, where a Professional selling plan carries a recurring monthly charge regardless of how much you sell.
The main cost is the referral fee, a percentage of the total sale price that Walmart deducts from each order. Referral fees vary by product category and typically fall between 6% and 15%, with most categories sitting toward the higher end and a smaller number of categories charging less. Because the exact percentages are set per category and can change, you should always confirm the current rate for your products against Walmart’s official fee reference before you price anything.
Actionable Insight: Build the referral fee into your pricing from day one, not as an afterthought. On a thin-margin product, the difference between an 8% and a 15% referral fee can be the difference between profit and loss on every unit. Model the fee, your product cost, shipping and any fulfilment charges together before you publish a listing.
If you use Walmart Fulfillment Services (more on this below), you also pay fulfilment fees based on the size and weight of each item shipped, plus monthly storage fees for inventory held in Walmart’s warehouses. Sellers who ship orders themselves avoid these charges but take on their own packing, postage and delivery responsibilities instead.
To understand your true profit per order, you need to combine three numbers: the referral fee, your landed product cost, and your fulfilment cost. A simple way to keep this honest is to run each product through a cost model before listing. Our free landed cost calculator helps you work out the fully loaded cost of imported goods, and our cost of goods sold calculator helps you track the underlying product cost that every marketplace fee is charged on top of.
For the authoritative, current breakdown of referral percentages by category and any fulfilment charges, see Walmart’s own Marketplace pricing reference and Seller Help fee guides. Treat those pages as the source of truth, because published category percentages shift over time and a marketplace’s own documentation will always be more current than a third-party summary.
Unlike Amazon, where almost anyone can open a selling account in an afternoon, Walmart Marketplace runs an application and approval process. Walmart wants to know that you can deliver a good customer experience before it lets you list alongside its own inventory. The upside of that friction is less competition once you are in.
You will generally need the following before you apply:
The application itself walks through several steps inside Walmart Seller Center: verifying your business, agreeing to the Retailer Agreement, completing your seller profile and tax forms, setting up payments, and configuring shipping. Walmart reviews the information and approves accounts that meet its standards. Approval timelines vary, so do not build a launch date around an instant turnaround.
Actionable Insight: Walmart weighs your existing ecommerce track record heavily. Before applying, tidy up the metrics on your current channels: bring down cancellation and defect rates, sort out late shipments, and make sure your business details match across every document. A clean history is the single biggest thing in your favour.
Once you are approved, the work shifts to building out your catalogue. This is where having a clean, well-structured product record pays off. Every listing needs accurate identifiers, attributes, images and pricing, and the cleaner your underlying data, the faster you can publish and the fewer listing errors you will fight later. If you have not centralised your product data yet, our guide to the item master explains how to build a single source of truth for every product attribute before you push listings to a new marketplace, and our SKU number guide covers how to structure the internal codes that tie your inventory together across channels.
How you fulfil orders shapes your costs, your delivery speed and how visible your listings are. Walmart gives you two main routes.
Walmart Fulfillment Services (WFS) is Walmart’s own fulfilment network. You send inventory to Walmart’s warehouses, and Walmart stores it, picks and packs orders, ships them, and handles much of the related customer service and returns. In exchange you pay fulfilment fees per unit plus monthly storage fees. The advantages are fast, reliable delivery and the trust signals that come with Walmart handling the shipment, which can lift conversion. WFS items are also more likely to qualify for fast-delivery tags that shoppers filter for.
Seller-fulfilled orders are shipped by you, from your own warehouse, your home, or a third-party logistics partner. You keep full control of packaging and inventory, and you avoid WFS storage and fulfilment fees, but you take on the cost and the performance risk yourself. Walmart still holds you to its delivery-speed and on-time standards, so slow or unreliable shipping will hurt your visibility regardless of who is doing the picking.
The right answer often depends on the product. Small, fast-moving, standard-sized items tend to do well in WFS, where the per-unit economics work and fast delivery drives sales. Bulky, slow-moving, fragile or high-variation items are sometimes cheaper and easier to fulfil yourself.
Actionable Insight: You do not have to choose one route for your whole catalogue. Many sellers put their best-selling, easy-to-ship SKUs into WFS to win fast-delivery badges and the Buy Box, while keeping bulky or low-velocity items seller-fulfilled. Split the decision SKU by SKU based on size, weight and turnover.
Whichever route you choose, the operational challenge is the same one every multichannel seller faces: keeping one accurate inventory count when the same stock can sell on Walmart, Amazon, your own store and elsewhere at the same time. Overselling on a marketplace that punishes cancellations is an expensive mistake. A good multichannel inventory management system updates every channel the moment a unit sells anywhere, so a Walmart order immediately decrements the stock available on your other listings.
Getting approved is only the start. The sellers who do well on Walmart are the ones who list cleanly and then compete hard for the Buy Box.
When you create listings, you can do it one item at a time, in bulk via spreadsheet, through an API integration, or by matching to products that already exist in Walmart’s catalogue. Strong listings share the same fundamentals you would recognise from any marketplace:
The Buy Box is the prominent “Add to Cart” placement that goes to the seller offering the best overall deal on a given item. Winning it is what turns impressions into orders. Walmart’s algorithm weighs price most heavily, alongside fulfilment speed, in-stock reliability and seller performance. The practical recipe is consistent: keep your total delivered price competitive, keep items in stock, ship fast (which is where WFS helps), and keep your defect and cancellation rates low.
Actionable Insight: Price suppression is the silent killer on Walmart. If a listing suddenly stops getting orders, check whether it has been flagged as overpriced before you assume the problem is demand. Walmart will quietly pull an overpriced item from the Buy Box and from search without an obvious error message.
Listing quality and pricing discipline are also far easier to maintain when your catalogue data is centralised rather than re-typed into each marketplace by hand. Pushing the same clean title, image set and attribute data to Walmart, Amazon and your own store from one source keeps listings consistent and cuts the listing errors that delay publishing. A multichannel listing tool lets you manage one product record and syndicate it to every channel, instead of maintaining a separate, slowly-diverging copy on each one.
Most sellers weighing up Walmart are already on Amazon, or considering both, so it helps to be clear about how they differ.
Cost structure. Walmart charges no monthly subscription, only referral fees on sales. Amazon’s Professional plan carries a recurring monthly fee on top of its referral fees. For lower-volume sellers, Walmart’s pay-only-when-you-sell model is gentler on cash flow.
Competition. Amazon’s marketplace is enormous and mature, with intense competition in most categories. Walmart’s third-party seller base has historically been smaller, so there is often more room to get noticed, particularly in categories Amazon has saturated.
Barrier to entry. Amazon is close to open registration. Walmart applies an approval process that favours established sellers with good metrics. That barrier is a cost when you are starting, and an advantage once you are inside.
Pricing culture. Both marketplaces care about price, but Walmart’s everyday-low-price identity makes its price monitoring especially aggressive. A pricing strategy that works on Amazon may need sharpening for Walmart.
Actionable Insight: Walmart and Amazon are not an either-or choice. The sellers who get the most from Walmart usually run it alongside Amazon and treat it as incremental reach, listing the same well-priced SKUs in both places and letting each marketplace bring its own audience. The real question is not which one, but how to run both without doubling your workload.
For a deeper comparison of the storefront-versus-marketplace decision more broadly, our Shopify vs Amazon guide covers the trade-offs between owning your own store and selling on a marketplace, many of which apply equally to Walmart.
Walmart Marketplace works best as one channel in a wider mix, not as your only storefront. The shopper who buys on Walmart is often a different person from the one who buys on Amazon, on TikTok Shop, or directly from your own Shopify store. Each channel reaches an audience the others miss, so adding Walmart to an existing setup is usually about incremental sales rather than replacing what you already do.
The catch is operational. Every channel you add multiplies the work of keeping stock counts accurate, listings consistent and orders flowing without delays. Sell the same item on Walmart, Amazon and your own store, and a single sale anywhere needs to reduce the available quantity everywhere, instantly, or you risk overselling. On a marketplace as unforgiving about cancellations as Walmart, that is a fast way to damage the very seller metrics that keep you in the Buy Box.
This is exactly the problem OneCart is built to solve. OneCart connects Walmart Marketplace alongside Amazon, Shopify, Shopee, Lazada, TikTok Shop and 20+ other channels into a single system, so you manage one catalogue, one inventory count and one order pipeline. When a unit sells on Walmart, your stock updates everywhere in real time. Listings are created and maintained from one product record rather than re-keyed channel by channel. Orders from every marketplace land in one queue your team works from. Instead of logging into half a dozen seller dashboards and reconciling them by hand, you run the whole operation from one place.
Actionable Insight: Add channels in the order of least operational pain, not just biggest audience. A new marketplace only adds profit if you can serve it without overselling or falling behind on dispatch. Get your inventory syncing automatically across your existing channels first, then plug Walmart in, so the new orders flow into a system that is already keeping itself accurate.
That way, Walmart becomes a growth lever rather than another inbox to babysit, and you can keep adding marketplaces without your operations team growing at the same rate as your sales.
There is no setup fee, no monthly subscription fee and no listing fee to sell on Walmart Marketplace. Your main cost is a referral fee on each sale, which typically falls between 6% and 15% depending on the product category. If you use Walmart Fulfillment Services, you also pay per-unit fulfilment fees and monthly storage fees. Always check Walmart’s official pricing reference for the current rates that apply to your categories.
Walmart runs an application and review process rather than instant sign-up. It looks for sellers who can serve US customers reliably, hold valid product identifiers, and ideally have a track record of good performance on other channels. Sellers with clean fulfilment metrics and complete, accurate business documentation tend to be approved more smoothly. Build in time for review rather than assuming a same-day launch.
No. You can ship orders yourself or through a third-party logistics provider, or you can use Walmart Fulfillment Services and let Walmart store, pack and ship for you. Many sellers use a mix, putting fast-moving, standard-sized items into WFS to win fast-delivery badges while fulfilling bulky or low-velocity items themselves. Whatever you choose, Walmart still holds you to its delivery-speed standards.
Yes, and most successful Walmart sellers do exactly that. The two marketplaces reach overlapping but distinct audiences, so running both usually adds incremental sales. The main challenge is operational: keeping inventory, pricing and orders in sync across channels. A multichannel platform that connects both marketplaces to one inventory count removes most of that friction and protects you from overselling.
