A Step-by-Step Guide to Selling on Walmart Marketplace as a New Seller in 2026

Selling on Walmart Marketplace looks intimidating when thirteen different "ultimate guides" tell you thirteen different things about how to start selling.

Most of them skip the parts that actually matter, like why Walmart rejects half the applications it receives or which fulfillment method gets you the 50% sales lift Walmart reps love to mention.

This guide cuts through the noise.

You'll get the real 6-step process, the current 2026 eligibility requirements, the actual referral fees by category, and answers to the four questions Walmart's official website buries five clicks deep.

By the end you'll know exactly what it takes to start selling, how to set up Seller Center the right way, which fulfillment method fits your business, and how Aura helps Walmart sellers win the Buy Box once you're approved.

Here's the 6-step shape we'll follow: Eligibility → Application → Onboarding → Listings → Fulfillment → Performance.

What Is Walmart Marketplace?

Walmart Marketplace is Walmart's third-party seller platform where independent businesses list products next to Walmart's own inventory on the walmart.com website. With more than 400 million monthly visits and roughly 200,000 active third-party sellers, it puts your catalog in front of millions of Walmart customers without the premium overhead of fighting for shelf space on Amazon.

It's not the same as being a Walmart vendor.

Walmart vendors sell their inventory directly to Walmart, which then resells it as a first-party retailer in store and online. Marketplace sellers keep ownership of their inventory and sell directly to customers, with Walmart taking a referral fee on each sale.

That distinction matters because the bar to become a Marketplace seller is much lower than becoming a vendor, and Walmart Marketplace offers stronger upside in 2026 than ever as Walmart continues to expand its third-party catalog and add new sales channels for sellers across multiple departments.

Why Sell on Walmart Marketplace in 2026?

Selling on Walmart Marketplace makes sense if you already have ecommerce experience and want a lower-competition alternative to Amazon. No monthly fees, 400M+ monthly visits, and a referral fee structure that rivals Amazon's mean you get exposure to one of the most recognized retail brands in the U.S. without paying for the privilege.

A Massive, Trust-Heavy Customer Base

Walmart.com pulls in more than 400 million monthly visits, which puts Aura's Walmart sellers in front of millions of customers who already trust the Walmart brand from years of shopping in store. That kind of warm audience of ready-to-buy customers is something most ecommerce platforms can't deliver at any price.

That trust transfer is the underrated benefit. A shopper who'd never buy from a random Shopify website will happily check out on Walmart's website because the Walmart name is on the page.

For new marketplace sellers, that trust shortcut compresses months of brand-building work into a single approved application, which means you can start selling to a warm audience from day one.

No Monthly Fees and No Setup Charges

Unlike Amazon's Professional Seller account, Walmart charges zero monthly fees to sell on its marketplace. There are no setup charges, no listing fees, and no $39.99/month base cost just to keep your listings live.

That makes Walmart Marketplace a low-risk place to test a new sales channel. You only pay a referral fee when you actually make a sale, which is one of the most forgiving fee structures in U.S. ecommerce.

Less Competition Than Amazon

Walmart has roughly 200,000 active third-party sellers compared to Amazon's nearly 2 million. There aren't as many sellers competing in the same product category, which gives new marketplace sellers room to win customers without burning their entire margin on ads.

Fewer competitors per listing means a higher chance of winning the Buy Box, which drives the vast majority of marketplace sales. Pair that with a smart Walmart repricer and you can dominate a category that Amazon sellers wouldn't touch.

How to Sell on Walmart Marketplace in 6 Steps

Selling on Walmart Marketplace breaks down into a clean six-step process: confirm you meet the eligibility requirements, submit your seller application, complete Seller Center onboarding, create and optimize your product listings, choose a fulfillment method, and manage performance to keep your account in good standing.

Here's the full sequence:

• Step 1: Confirm eligibility
• Step 2: Submit your seller application
• Step 3: Complete Seller Center onboarding
• Step 4: Create and optimize listings
• Step 5: Choose a fulfillment method
• Step 6: Manage performance

Each step takes anywhere from a few minutes to a few days. Plan on 2-4 weeks total from clicking apply to your first sale going live.

Step 1 — Confirm You Meet Walmart's Eligibility Requirements

Not everyone can start selling on Walmart Marketplace right away. Walmart requires every applicant to hold a U.S. Business Tax ID (EIN), provide a W-9 or W-8 form, supply a verified business address, and demonstrate marketplace or ecommerce success on platforms like Amazon, eBay, or their own Shopify website. GS1-certified UPC codes for products are also required.

Walmart's official checklist of what every seller needs:

• U.S. Business Tax ID (EIN): SSN is not accepted. Walmart requires a registered legal business with a taxpayer identification number issued by the IRS.
• W-9 or W-8 form: Required for tax compliance during the application process.
• Verified business address: A real U.S.-based business address, not a P.O. box.
• Proven marketplace or ecommerce success: A track record on Amazon, eBay, Shopify, or other online marketplaces that shows you can fulfill orders at scale.
• GS1 GTIN/UPC codes: Valid product identifiers for every item you plan to list.
• Catalog compliance: Your products must comply with Walmart's Prohibited Products Policy.

If you're missing any one of these, your application gets denied. Fix the gap before you click apply, not after.

Step 2 — Submit Your Walmart Seller Application

Visit the marketplace.walmart.com website to start the seller application process. The form takes about 10-15 minutes to complete and asks for your legal business name, EIN or taxpayer identification number, W-9 or W-8 form, verified business address, and bank account details. Walmart's review then takes anywhere from a few days to several weeks depending on application volume and how complete your submission is.

Have these documents ready before you click apply:

• Business name that exactly matches your IRS records
• EIN and W-9 or W-8 form
• Verified business address and primary contact email
• Bank account info for payouts
• A list of the product categories you plan to sell in

Walmart requires sellers to provide consistent business information across legal documents, your website, and bank accounts to avoid verification delays. If your EIN says one business name and your bank account says another, expect a flag during the application process.

Step 3 — Complete Seller Center Onboarding

Once you're approved, you'll set up your Seller Center account, finish tax setup, link a payment processor (Payoneer is the default), configure shipping, accept the Retailer Agreement, and start listing products on Walmart Marketplace. Onboarding usually takes 1-2 days if your business documents are in order.

Your Seller Center onboarding checklist:

• Accept the Retailer Agreement before anything else unlocks
• Complete tax setup by submitting your W-9 form
• Link a payment processor (Payoneer or Hyperwallet) so Walmart can pay you
• Configure shipping settings for the methods you'll offer
• Build your company profile with logo, return address, and contact info

Don't skip the company profile. Walmart customers see the seller name and details on every product page, and a complete profile signals legitimacy that boosts conversion rates.

Step 4 — Create and Optimize Your Product Listings

Walmart Marketplace gives sellers three ways to create product listings: single-item entry through Seller Center, bulk upload via spreadsheet, or API integrations for large catalogs. Successful product listings combine accurate UPCs, high quality images, and rich descriptions that match how Walmart customers actually search.

The three listing methods at a glance:

• Single-item entry: Best for sellers with 10-50 products. Manual but precise.
• Bulk upload: Spreadsheet template that handles 50-1,000+ products at once.
• API integrations: For large catalogs and recurring updates from your existing systems.

Lean on high quality images and detailed descriptions to climb higher in Walmart's search results. Once your products are live, Walmart's Listing Quality Dashboard scores every listing on completeness, content quality, and conversion-readiness, and a higher score earns you more visibility in the right product department.

Title Best Practices

Walmart titles should run 50-75 characters. Lead with the brand name, then the key product feature, then the model or size variant.

Don't keyword-stuff. Walmart's algorithm penalizes titles that read like a search query dump, and customers bounce when titles look spammy.

Using relevant, high-volume search terms in product names and descriptions is crucial for optimizing listings on Walmart Marketplace and helping shoppers find your catalog through the right search results.

Image Requirements

Primary product images must be at least 1000x1000 pixels on a pure white background. Use high quality JPEGs only.

Add lifestyle shots, alternate angles, and feature callouts as secondary images to increase conversions and reduce returns.

Description Format

Walmart recommends bullet points to highlight benefits and specs, and a minimum of 150 words for every product description. Write with the search terms customers actually type, not the marketing language your brand team prefers.

Step 5 — Choose Your Fulfillment Method

Walmart Marketplace gives sellers two fulfillment options: self fulfilling orders from your own warehouse or a third party logistics provider, or Walmart Fulfillment Services (WFS), which handles storage, packing, shipping, and returns from Walmart's fulfillment centers. Whichever route you pick, every order has to ship from a U.S.-based warehouse to keep your account in good standing.

Self Fulfilling Orders

With self fulfilling, you keep inventory in your own warehouse or 3PL and handle every part of the order, from packing to shipping to customer support.

The upside is full control over your stock and shipping standards. The downside is full responsibility, which means a single missed delivery can tank your seller metrics.

This path makes sense for sellers who already have logistics dialed in and don't want to send inventory to a Walmart facility.

Walmart Fulfillment Services (WFS)

WFS is Walmart's answer to Amazon FBA. You send inventory to Walmart's fulfillment centers and Walmart handles storage, packing, shipping, and returns automatically.

WFS sellers get faster shipping speeds and higher Buy Box win rates because Walmart's logistics network does the heavy lifting. WFS sellers see up to a 50% sales lift on average compared to self-fulfilled listings, thanks to faster shipping badges, free TwoDay tags, and stronger placement in Walmart's search results.

WFS is the closest thing Walmart has to FBA, and for sellers who care about scaling quickly, it's the path of least resistance. See our complete WFS guide for fee structures and best practices.

Walmart supports four shipping speeds: Value (6-7 days), Standard (3-5 days), TwoDay (2 days), and OneDay (1 day). Sellers enrolled in the TwoDay Delivery program reduce cart abandonment and earn premium placement in search results.

Step 6 — Manage Performance and Customer Experience

Walmart sets strict performance standards that took effect in April 2026: a valid tracking rate of at least 99%, on-time delivery of at least 90%, a cancellation rate below 2%, a seller response rate of at least 95%, and a negative feedback rate below 2%. Falling below any threshold reduces visibility and Buy Box eligibility, and repeated violations can lead to account suppression or termination.

Performance Standards

Walmart tracks every seller against these core metrics:

• Valid tracking rate: ≥99%
• On-time delivery rate: ≥90%
• Cancellation rate: ≤2%
• Seller response rate: ≥95%
• Negative feedback rate: ≤2%
• Refund rate: ≤6%

Drop below the threshold on any of these and Walmart starts suppressing your listings from search and the Buy Box. Protect your store metrics before you protect your margins.

Customer Experience and Returns

Walmart expects sellers to reply to customer inquiries within 48 hours to keep their Seller Response Rate healthy, weekends included. Slow replies hurt your customer experience score the same way late shipments do.

Walmart maintains a 30-day return window for most Marketplace items, although some categories may differ. WFS handles returns automatically. Sellers are responsible for providing a return label and processing refunds quickly if they are self fulfilling orders on Walmart Marketplace.

Customer reviews and order confirmation timing both feed into Walmart's seller rating, so set expectations clearly in your listing copy and follow through.

Pricing Compliance

You have to keep your prices competitive across every sales channel you sell on, or Walmart's pricing rules will quietly suppress your listings. The platform's automated price comparison crawls the web around the clock, and a single overpriced SKU can vanish from search overnight.

Use Walmart Price Analytics to monitor your prices against the competitive set, and keep promotional discounts within the 180-day max and 10% strikethrough threshold. For a complete framework, read our breakdown of Walmart pricing strategies.

Boost Visibility With Sponsored Products

Walmart Connect Sponsored Products is Walmart's pay-per-click ad platform, similar to Amazon Sponsored Products. You bid on keywords and pay only when customers click your ad in Walmart's search results.

Wait until you've collected at least 30 days of organic data before launching ads. That baseline tells you which products convert without paid help and which ones need a push.

Cost per click varies by category, but most sellers see profitable returns once they layer Sponsored Products on top of strong organic listings.

How Much Does It Cost to Sell on Walmart Marketplace?

Walmart Marketplace charges a referral fee on every sale, usually between 5% and 15% depending on the product category. There are no monthly fees, no setup charges, and no listing fees, so the only thing you pay is the referral fee Walmart skims after each order closes.

A sample of referral fees by category:

• Apparel & Accessories: 15%
• Consumer Electronics: 8% to 15% (tiered by price)
• Books, Music, Video: 15%
• Beauty: 8% to 15%
• Home & Garden: 12% to 15%
• Automotive & Powersports: 12%
• Tires & Wheels: 10%

For a full fee table by product category, see our complete Walmart seller fees breakdown.

If you use WFS, expect additional storage and fulfillment fees on top of the referral fee. Self fulfilling sellers skip those costs but eat shipping and warehouse expenses on their own.

Is It Hard to Get Approved to Sell on Walmart Marketplace?

Walmart Marketplace approval is harder than Amazon's open registration. The application process prioritizes sellers with proven marketplace or ecommerce success on platforms like Amazon, eBay, or their own ecommerce website. Most rejections come from incomplete applications, missing GS1 UPC codes, or businesses without a verified U.S. taxpayer identification number and address.

The most common reasons applications get denied:

• Missing or invalid EIN (SSNs are auto-rejected)
• Inconsistent business info across the application, EIN, website, and bank account
• No prior ecommerce success to point to
• Non-U.S. business entity without the right tax forms
• Catalog includes prohibited products under Walmart's policy

Approval timing varies wildly. Some sellers get approved in a few days, others wait several weeks. Application volume and submission completeness are the two biggest factors.

For the full list of rejection reasons and how to fix each one, read why Walmart Marketplace applications get denied.

How Aura Helps Walmart Marketplace Sellers Win

Once you're approved, the next challenge is winning the Buy Box. Aura is a Walmart and Amazon repricer built for marketplace sellers who want to compete on price without manually adjusting listings every hour. It connects to Walmart Seller Center, monitors competitor pricing in real time, and adjusts your prices automatically inside the rules you set.

Three things Aura does for Walmart sellers:

• Real-time competitor monitoring across the Walmart Marketplace
• Automated price changes within seller-defined min and max rules
• Buy Box win rate optimization without manual intervention

The Buy Box drives the vast majority of Walmart Marketplace sales, and price is the single biggest factor in winning it from your customers. Aura handles that loop in the background so you can focus on finding new products and growing your catalog. Learn more about Aura's Walmart repricer.

Walmart Marketplace FAQs

A few questions new sellers ask most often, with quick answers.

How long does Walmart approval take?

The Walmart Marketplace application process usually takes 2-4 weeks, but timing varies based on application volume and how complete your submission is. Sellers with all documents in order, a clear ecommerce track record, and a clean catalog can sometimes get approved in under a week.

Do I need an LLC to sell on Walmart Marketplace?

You don't need an LLC specifically, but you do need a registered legal business with a U.S. EIN or taxpayer identification number. Sole proprietors with an EIN qualify, as do LLCs, S-corps, and C-corps. Walmart will not accept SSNs in place of an EIN under any circumstances.

Can I sell on Walmart without my own brand?

Yes. Both resellers and private-label sellers qualify for Walmart Marketplace as long as they meet the eligibility requirements and their products comply with Walmart's catalog policies. You don't need a registered trademark or your own brand to apply, though branded sellers tend to get approved faster.

What's the difference between Walmart Marketplace and Walmart.com?

Walmart Marketplace is the third-party seller program where independent businesses list and sell their own inventory through the walmart.com website. Walmart.com first-party is Walmart's direct supplier program, where Walmart buys products wholesale and resells them itself, both online and in store. Marketplace sellers keep ownership of their inventory; vendors do not.
