Walmart has quickly become one of the fastest-growing eCommerce marketplaces in the world. For online sellers looking to diversify beyond Amazon, Walmart Marketplace presents a major opportunity.
By the end of 2024, Walmart Marketplace surpassed 150,000 third-party sellers, and that number is projected to grow by another 20% by late 2025. This growth is fueled by increasing demand for alternative marketplaces and Walmart’s continuous investment in its digital infrastructure.
Today, Walmart.com attracts over 120 million monthly visitors, giving sellers access to a massive customer base actively searching for products.
At the center of Walmart’s marketplace ecosystem is Walmart Seller Central—a powerful platform that allows sellers to manage listings, orders, fulfillment, advertising, and performance metrics from a single dashboard.
In this guide, our marketplace experts at EcomRanker walk you through everything you need to know about setting up, managing, and scaling your business using Walmart Seller Central.
What is Walmart Seller Central?
Walmart Seller Central—sometimes called Seller Center—is the main platform sellers use to manage their operations on Walmart Marketplace.
Through Seller Central, sellers can:
- Create and manage product listings
- Process and track customer orders
- Monitor inventory levels
- Analyze performance metrics
- Manage pricing strategies
- Run advertising campaigns
Unlike Amazon, Walmart follows a selective seller approval process. Only businesses that meet Walmart’s quality and performance standards are allowed to sell on the platform.
While this approval process may seem strict, it actually benefits sellers because there is less competition compared to Amazon.
Currently, Walmart accounts for less than 10% of total U.S. marketplace GMV, but its growth trajectory is extremely strong. Analysts predict Walmart’s eCommerce revenue could reach $82.6 billion by 2025, up significantly from $66 billion in 2023.
Who Should Sell on Walmart Marketplace?
Walmart Marketplace works particularly well for sellers with strong operational capabilities.
Ideal sellers include:
- Direct-to-consumer (D2C) brands with multiple products
- Established Amazon sellers expanding into new marketplaces
- Multi-channel retailers with strong logistics systems
Walmart Seller Central also integrates with many external tools and ERPs through APIs, making it suitable for businesses managing large product catalogs.
How to Set Up Your Walmart Seller Central Account
Getting started with Walmart Marketplace begins with submitting an application.
Step 1: Access the Marketplace Application
Visit marketplace.walmart.com and begin the seller application process.
You’ll need to provide:
- U.S. Business Tax ID (EIN)
- W-9 or W-8 tax documentation
- U.S. business address
- Product catalog information (categories and SKU count)
- Sales performance data from other marketplaces (Amazon, Shopify, etc.)
Step 2: Application Approval Timeline
If your application meets Walmart’s requirements, approval typically takes between 2–5 business days.
However, approval depends heavily on the quality of your documentation and your marketplace selling history.
Step 3: Complete the Post-Approval Setup
Once approved, sellers should complete several important setup steps.
These include:
- Completing your Partner Profile
- Connecting payment through Payoneer
- Choosing a fulfillment method
- Uploading product listings
- Running testing environments for certain product categories
Pro Tips for Faster Walmart Seller Approval
Experienced marketplace sellers often speed up approval by following these best practices:
- Use a professional domain-based email address
- Upload products using Walmart’s latest Item Spec file format
- Include valid UPC or GTIN codes for most products
- Provide clear evidence of marketplace selling experience
Working with a Walmart marketplace consulting agency can also simplify the onboarding process.
Walmart Seller Central Requirements (Beyond the Basics)
Walmart’s public requirements are just the starting point. The platform also evaluates sellers based on operational readiness.
Official Requirements
To qualify, sellers typically need:
- A registered U.S. business with an EIN
- The ability to fulfill at least 50 orders per day
- A 99% on-time shipping rate

Additional Factors Walmart Considers
Walmart also analyzes seller performance across other platforms.
This includes evaluating:
- Product catalog quality
- Image compliance (minimum 1000 × 1000 resolution)
- Customer return policies
- Integration capability with Walmart’s API ecosystem
Many rejected applications occur because of incomplete product catalog data or poorly structured listings.
