How to Sell on Walmart Marketplace: Complete Seller Guide 2025

Why Walmart Marketplace Deserves Serious Attention in 2026

Walmart.com has firmly established itself as the second-largest e-commerce marketplace in the United States, trailing only Amazon in monthly traffic and seller count. What makes Walmart Marketplace strategically interesting for sellers in 2026 is not just its size, but its structural position: it consistently attracts a buyer demographic that skews toward value and everyday essentials, it has substantially lower seller competition than Amazon in most categories, and Walmart continues to invest heavily in marketplace infrastructure, logistics, and advertising tools.

For sellers already established on Amazon, Walmart represents the highest-leverage incremental channel with the lowest learning curve: the mechanics of product listings, fulfillment integration, and PPC advertising are similar enough to transfer existing knowledge. For brands and retailers new to marketplace selling, Walmart's more curated (and more selective) seller base means less commoditized competition and potentially faster organic visibility.

This guide covers everything sellers need to know about operating on Walmart Marketplace: the application and approval process, fee structure, fulfillment options, listing optimization, advertising, and competitive strategy — including how Walmart compares to Amazon at each stage.

Understanding Walmart Marketplace: Platform Overview

How Walmart Marketplace Works

Walmart Marketplace is a third-party seller program on Walmart.com. Walmart itself sells products directly (first-party), but marketplace sellers list and sell products alongside Walmart's own inventory. From a customer's perspective, both appear on the same product pages; the “sold and shipped by [Seller Name]” designation is the differentiator.

Key characteristics of the marketplace model:

• Seller responsibility: Marketplace sellers own pricing, inventory management, and fulfillment (or opt into Walmart Fulfillment Services)
• Walmart brand protection: Walmart enforces strict quality standards; sellers violating customer experience thresholds (cancellation rate, late shipment rate, refund rate) face suspension
• No monthly seller fee: Walmart charges no subscription fee to list on the marketplace — unlike Amazon's $39.99/month Professional plan
• Referral fee model: Walmart takes a percentage of each sale (varies by category), similar to Amazon's referral fee structure
• Walmart.com traffic: Sellers benefit from Walmart's enormous organic traffic base from existing .com customers and physical store shoppers who cross-shop online

The Competitive Landscape: Walmart vs Amazon Seller Count

Amazon hosts over two million active third-party sellers. Walmart Marketplace has grown significantly but remains a fraction of that — likely in the range of 100,000-150,000 active sellers as of 2026. This means dramatically less competition for search placement in most categories. A product that might rank on page 5 on Amazon could rank on page 1 on Walmart with the same listing quality, simply because fewer sellers are competing for that position.

The caveat: Walmart's search algorithm and customer conversion rate differ from Amazon's. Walmart shoppers tend to be more price-sensitive and have lower brand loyalty to marketplace sellers (vs. Amazon shoppers who have been conditioned to purchase from third-party sellers for over two decades). Understanding these behavioral differences informs listing strategy, pricing, and product selection.

Getting Approved: The Walmart Marketplace Application Process

Eligibility Requirements

Walmart is more selective than Amazon about who can sell on the marketplace. Before applying, sellers should understand Walmart's published eligibility criteria:

• Business registration: Valid US Business Tax ID (EIN), not a Social Security Number
• US business address: A verified US business address (a PO box is not sufficient)
• Product history: Demonstrated e-commerce history — existing Walmart.com presence, Amazon presence, or an established DTC website strengthens the application
• Catalog and category fit: Products must comply with Walmart's prohibited items policy and fit within accepted categories
• Fulfillment capability: Ability to meet Walmart's shipping standards (two-day delivery is increasingly important; Walmart Fulfillment Services is an option for sellers without their own logistics)

Sellers with existing Amazon presence, an established Shopify store, or brand registration tend to have the strongest application outcomes. Walmart has historically been more selective in high-category-overlap areas (like low-margin commodities) and more open to sellers with differentiated products, existing customer reviews, and professional brand presence.

The Application Steps

1. Create a Marketplace account: Apply at marketplace.walmart.com with your business information
2. Business verification: Provide EIN, US business address, business contact, and primary category of products
3. Product information: Submit information about your catalog size, product categories, and whether products are branded or private label
4. Review period: Walmart typically reviews applications within 1-4 weeks; complex applications or those with incomplete information can take longer
5. Onboarding: Approved sellers are walked through account setup, shipping profile configuration, and the Partner Profile dashboard
6. Test order: Before going fully live, Walmart may require a test order to verify fulfillment capability meets their standards

Common Reasons for Application Rejection

• No verifiable US business address or tax ID
• Products that duplicate Walmart's own private label in a category without meaningful differentiation
• Prohibited categories (adult products, certain chemicals, weapons accessories)
• No demonstrable e-commerce history or customer review history
• Poor seller performance metrics from other marketplaces (if discoverable)

Walmart Marketplace Fee Structure

Referral Fees by Category

Walmart's referral fees are broadly competitive with Amazon's — in some categories lower, in others comparable. Key category fees:

Note: Walmart updates fees periodically. Always confirm current category fees in your Seller Center dashboard before finalizing pricing models. The above reflects publicly available fee schedules as of 2026 and may not reflect recent updates.

No Monthly Subscription Fee

One of Walmart Marketplace's most meaningful structural advantages over Amazon: there is no monthly or annual seller subscription fee. Amazon charges $39.99/month for the Professional plan required for most serious sellers. For sellers with seasonal inventory or those just building out a Walmart presence, the absence of a subscription fee reduces fixed cost exposure.

Walmart Fulfillment Services (WFS) Fees

Walmart Fulfillment Services (WFS) is Walmart's equivalent of Amazon FBA. Sellers ship inventory to WFS centers; Walmart handles storage, picking, packing, shipping, and customer returns. WFS unlocks the “Fulfilled by Walmart” badge, which signals fast shipping to customers and improves search placement. Fee structure:

• Fulfillment fee: Per-unit fee based on weight, similar in structure to Amazon FBA (typically $3-8 for standard items)
• Storage fee: Monthly storage fee based on cubic footage (comparable to Amazon's rates)
• Inbound shipping: Sellers pay their own freight to WFS centers
• No WFS setup fee: Unlike some 3PL arrangements, there is no enrollment fee for WFS

Fulfillment Options on Walmart Marketplace

Option 1: Seller-Fulfilled (Dropship or Own Warehouse)

Seller-Fulfilled means the marketplace seller handles storage and shipping directly from their own warehouse, 3PL partner, or via dropshipping from a supplier. Requirements:

• Must meet Walmart's on-time delivery and shipping speed standards (two-day delivery preferred)
• Cancellation rate must stay below 2%
• On-time delivery rate must stay above 99%
• Valid tracking must be provided on all orders

Walmart monitors these metrics continuously. Sellers whose metrics fall below thresholds receive warnings and can face listing suspension or account termination. Unlike Amazon where a seller can operate FBM alongside FBA, on Walmart the seller-fulfilled path requires robust logistics operations to maintain good standing.

Option 2: Walmart Fulfillment Services (WFS)

WFS is the recommended path for most sellers entering Walmart Marketplace, particularly those without robust fulfillment infrastructure. Benefits beyond operational simplicity:

• “Two-Day Delivery” badge: WFS-fulfilled products automatically earn the Two-Day Delivery badge, a significant conversion driver
• Search placement boost: Walmart's algorithm reportedly favors WFS products in search ranking, similar to Amazon's treatment of FBA
• No seller performance risk on logistics: Fulfillment metrics are managed by Walmart, not the seller
• Returns handled by Walmart: Customer returns go to WFS centers, not back to the seller's facility

Eligibility for WFS

Not all products are WFS-eligible. Key restrictions:

• Products must be under 150 lbs
• Dimensions under 108″ in length and 165″ in combined girth and length
• Hazardous materials, certain regulated products, and products requiring special handling may be excluded
• Products must have a valid GTIN (UPC, EAN, or ISBN)

Creating and Optimizing Walmart Listings

The Listing Structure

Walmart product listings contain several key content fields, each affecting search visibility and conversion:

• Product Name (Title): Up to 200 characters; Walmart recommends including brand, key descriptor, size/quantity, and distinguishing attributes
• Key Features (Bullets): Six bullet points describing key product attributes and benefits
• Product Description: Free-form text allowing detailed description, usage guidance, and feature elaboration
• Images: Minimum one image; up to 20 images and 360-degree views recommended; main image must be on white background (same standard as Amazon)
• Attributes: Category-specific structured fields (color, material, dimensions, compatibility) that power faceted search and filtering

Walmart Search Algorithm: Key Ranking Factors

Walmart's search algorithm — called Polaris — operates differently from Amazon's A9/A10. Key ranking factors:

• Price competitiveness: Walmart places heavy weight on competitive pricing, both against other Walmart.com sellers and against prices on Amazon and other major retailers (Walmart's price parity policy means your price on Walmart should not exceed prices on other channels where possible)
• Listing quality score: Walmart assigns each listing a “Listing Quality Score” visible in Seller Center; higher scores correlate with better organic placement
• Fulfillment badge: Two-Day Delivery and WFS-fulfilled products are favored
• Review count and rating: Customer reviews affect both ranking and conversion; the review threshold to be competitive is generally lower on Walmart than Amazon
• Catalog data completeness: Filling all required and optional attribute fields improves both ranking and discoverability in filtered search
• Sales velocity and conversion: Products that convert well at their current traffic level are rewarded with more traffic

The Listing Quality Score

Walmart's Listing Quality Score (LQS) is a 0-100 metric calculated based on:

• Content completeness (title, bullets, description, attributes)
• Image quality and count
• Customer ratings and review count
• Offer quality (in-stock rate, competitive pricing)
• Post-purchase performance (returns, cancellations)

Walmart Seller Center displays the LQS for each product and provides specific recommendations for improvement. Products with LQS above 80 consistently perform better in organic search. Unlike Amazon, where listing quality is somewhat opaque, Walmart's explicit score gives sellers a clear optimization roadmap.

Walmart Marketplace Advertising

Walmart Connect: The Advertising Platform

Walmart's advertising platform (formerly Walmart Advertising Partners, now branded as Walmart Connect) offers several ad formats for marketplace sellers:

• Sponsored Products: CPC ads that appear in search results and product pages; the equivalent of Amazon Sponsored Products — the most commonly used format for marketplace sellers
• Sponsored Brands: Header ads at the top of search results that feature a brand logo and multiple products; available to brand-registered sellers
• Walmart DSP: Display advertising that reaches Walmart's audience off-site (across the open web); requires larger budgets and is typically used by brands, not individual sellers

CPCs on Walmart are generally lower than Amazon for comparable keywords, partly because of the smaller seller population competing for ad placement. This makes early organic ranking campaigns more capital-efficient on Walmart than on Amazon, though the overall traffic volume is also lower.

Advertising Strategy for New Marketplace Entrants

Sellers launching on Walmart for the first time should expect to run Sponsored Products campaigns for at least 60-90 days to build sales history, improve BSR, and accumulate reviews before relying heavily on organic traffic. A reasonable launch advertising budget is 20-30% of revenue during this phase, tapering to 10-15% as organic visibility improves.

Walmart's Price Parity Policy

One of the most important policy distinctions between Walmart and Amazon is Walmart's price parity requirement. Walmart expects that the price listed on Walmart.com should not be higher than the price for the same product on other online channels, including Amazon, the seller's own website, and other marketplaces.

In practice, Walmart monitors competitor prices and may suppress listings (remove the “Add to Cart” button) if it detects that a product is significantly cheaper elsewhere. This is called “price suppression” — the listing remains visible but becomes unpurchasable, effectively removing it from the marketplace until the price is brought in line.

For sellers running across multiple channels (Amazon, Walmart, DTC website), this requires coordinated pricing discipline. Price tracking tools that monitor cross-marketplace pricing — including the capabilities described in our Amazon price tracking tools comparison — become genuinely important for avoiding price suppression on Walmart while maintaining competitiveness on Amazon.

Walmart Marketplace vs Amazon: A Practical Comparison

Product Strategy: What Sells Best on Walmart Marketplace

Categories Where Walmart Has Structural Advantage

Walmart's core customer base tends to over-index on categories aligned with its brick-and-mortar heritage: everyday essentials, consumables, home goods, and value-priced products. Categories where Walmart.com performs particularly strongly:

• Household consumables: Paper products, cleaning supplies, laundry detergent — categories where Walmart's grocery-adjacent customer base and price perception drive strong conversion
• Grocery and pantry: Non-perishable food, beverages, snacks — Walmart's grocery credibility gives it higher shopper trust in this category vs. Amazon
• Pet food and supplies: Value-tier pet food especially; consumables with subscribe-and-save potential
• Baby products: Diapers, wipes, baby food — parents who shop Walmart for grocery often cross into baby on the same session
• Automotive accessories: Walmart has strong automotive accessory traffic from its in-store auto center customers
• Electronics accessories: Phone cases, chargers, cables — lower price points align with Walmart's core demographic
• Sports and outdoor basics: Team sports equipment, fitness basics, camping essentials

Products That Perform Relatively Better on Amazon

Some product profiles are harder to succeed with on Walmart due to buyer behavior and category depth:

• Premium or luxury-positioned products (Walmart shoppers tend toward value)
• Highly differentiated private label in niche sub-categories (smaller audience discovering niche products)
• Products requiring extensive review counts to convert (Walmart's review ecosystem is less mature)
• Digital accessories and tech that require ecosystem trust (Apple accessories, gaming peripherals)

The Pricing Dynamic on Walmart

Price is more determinative on Walmart than on Amazon. Amazon shoppers will pay a meaningful premium for better reviews, more detailed listings, or brand recognition. Walmart shoppers compare prices more directly. This means price competitiveness is not optional on Walmart — it is the primary driver of both organic search placement (via Walmart's algorithm) and conversion once a customer lands on the product page.

The practical implication: before listing on Walmart, analyze competitive pricing carefully. Listing at a price 20% above the lowest comparable option on Walmart.com will result in poor organic placement and low conversion regardless of listing quality. This is where cross-marketplace price tracking — seeing simultaneously what your products are priced at on Amazon and Walmart — becomes operationally necessary.

Seller Performance Metrics: What Walmart Monitors

Walmart tracks seller performance across several dimensions and takes enforcement action when metrics fall below thresholds:

Walmart's Unique Seller Tools and Programs

Walmart Free Assembly (Home Delivery and Assembly)

For qualifying products (primarily furniture and large items), Walmart Free Assembly provides white-glove delivery and in-home assembly through a network of service providers. Sellers whose products qualify can list this as a delivery option, increasing conversion for customers who want help with setup.

Brand Portal

Walmart's Brand Portal (analogous to Amazon Brand Registry) allows brand owners with registered trademarks to protect their listings from unauthorized sellers and content changes. Brand Portal also provides access to enhanced content capabilities (similar to Amazon's A+ Content) and brand analytics.

Replenishment and Inventory Management Tools

Walmart Seller Center provides inventory management dashboards, reorder recommendations, and inbound shipment management for WFS sellers. The interface has improved significantly in recent years and is now reasonably comparable to Amazon's FBA inventory management tools.

Integrating Amazon and Walmart: Managing Multi-Channel Pricing

Most sellers on Walmart Marketplace are also on Amazon. Managing pricing across both channels requires systematic attention to avoid Walmart price suppression while maintaining competitive positioning on Amazon. Key operational principles:

Set a Baseline Pricing Rule

As a starting point: price Walmart.com at the same level as Amazon or slightly below. Walmart's price parity policy means being higher than Amazon risks suppression; being lower on Walmart than Amazon can technically trigger Amazon's price parity monitoring (Amazon has equivalent mechanisms that can suppress buy box if your product is significantly cheaper elsewhere). In practice, matching prices across channels is the lowest-friction approach.

Monitor Competitor Pricing on Both Platforms

Competitor pricing changes on Amazon can trigger a cascade: if a competitor drops price on Amazon, you may need to match to maintain buy box. That same price drop, if it takes you below a threshold on Walmart, could affect your Walmart placement. Sellers who monitor competitor pricing on both platforms simultaneously can make coordinated adjustments rather than reactive ones.

This multi-marketplace pricing view is one of the core use cases for tools like Amazon Seller Central analytics platforms that go beyond single-channel tracking — and for more sophisticated sellers, enterprise platforms that aggregate pricing signals across channels into a unified dashboard. Our comparison of PLOTT DATA vs Jungle Scout covers how these tools differ in their approach to multi-marketplace visibility.

Common Mistakes Sellers Make on Walmart Marketplace

1. Treating Walmart as a Copy-Paste of Amazon

While the operational mechanics are similar, the buyer psychology and algorithm priorities differ. Listings optimized for Amazon keyword density don't always perform well on Walmart's Polaris algorithm. Attribute completeness, pricing, and the Listing Quality Score are relatively more important on Walmart than A9 keyword optimization is on Amazon.

2. Ignoring the Listing Quality Score

Many sellers list products on Walmart with minimal content (short titles, one image, no attributes) and wonder why organic performance is poor. The LQS is a visible, actionable metric — optimize it systematically before running advertising.

3. Launching Advertising Before Organic Foundation is in Place

Advertising drives traffic to product pages. If listing quality is poor, traffic converts poorly, ROAS is weak, and Walmart's algorithm learns negative conversion signals. Fix the listing (target LQS 80+) before investing in advertising.

4. Underestimating the Price Parity Policy

Sellers who run promotions or price changes on Amazon without updating Walmart risk suppression. A single suppressed listing during a high-demand period can represent significant lost revenue. Systematic cross-channel price monitoring prevents this.

5. Not Enrolling in WFS When Eligible

The Two-Day Delivery badge and algorithm favorability from WFS significantly outweigh the incremental fulfillment cost for most standard-size products. Sellers trying to optimize margin by self-fulfilling often find that lower conversion and poorer search placement on non-WFS products cost more than the fee differential.

Building a Long-Term Walmart Strategy

Phase 1: Establish and Validate (Months 1-3)

Focus on LQS, WFS enrollment for core SKUs, and initial Sponsored Products campaigns. Goal: generate first 20-50 reviews per product, establish baseline conversion rate metrics, and identify which products in your catalogue have the strongest Walmart fit based on category alignment and price competitiveness.

Phase 2: Scale the Winners (Months 4-9)

Double advertising spend on products showing strong ROAS and improving BSR. Expand the catalogue to adjacent products. Pursue Brand Portal if not yet enrolled. Test Sponsored Brands if catalogue depth supports it.

Phase 3: Optimize and Defend (Month 10+)

Focus on maintaining competitive pricing, responding to new entrants in your categories, and deepening Walmart-specific content (enhanced content via Brand Portal). Monitor competitor pricing changes as a systematic process rather than reactive spot-checking.

Key Takeaways for Walmart Marketplace Sellers

• Lower competition than Amazon in most categories — organic visibility is achievable faster with comparable effort
• No monthly seller fee reduces fixed cost exposure vs. Amazon's $39.99/month Professional plan
• Price is more determinative on Walmart than Amazon — prioritize competitive pricing before all other optimization
• WFS enrollment is strongly recommended for eligible standard-size products; the Two-Day badge and algorithm favorability are material conversion drivers
• Listing Quality Score is the single most actionable Walmart-specific optimization metric — target 80+ before investing in advertising
• Price parity policy requires systematic cross-channel pricing monitoring to avoid suppression on Walmart or buy-box loss on Amazon
• Customer base skews value-oriented — products that compete on price, quality-for-price, or everyday utility outperform premium or niche-positioning strategies
• Application selectivity means Walmart sellers face less commodity competition in most categories — quality of seller base is higher than Amazon's open enrollment

How PLOTT DATA Supports Walmart Marketplace Sellers

For sellers managing products across Amazon and Walmart simultaneously, the most operationally difficult challenge is pricing: maintaining competitive prices on both platforms, complying with Walmart's parity policy, and avoiding margin compression from undercutting on one platform to stay competitive on another.

PLOTT DATA's marketplace intelligence platform monitors pricing across Amazon, Walmart, and 60+ other global marketplaces — giving multi-channel sellers a unified view of competitor pricing behavior, promotional cadence, and product availability. Rather than managing separate monitoring tools per channel, sellers get a single data feed covering the competitive landscape on both platforms.

For brands managing broader category performance — tracking category share, monitoring new entrants, or analyzing seasonal pricing patterns — PLOTT DATA's category-level analytics provide the intelligence needed to make strategic decisions before the market shifts rather than after.
