Walmart’s ecommerce business continued to grow in Q4 FY2026. Global ecommerce sales increased 24%, while Walmart U.S. ecommerce grew 27%, with Marketplace contributing alongside store-fulfilled pickup, delivery, and advertising according to the Walmart Q4 FY2026 Earnings Release.

For sellers, the barrier to entry is relatively low. Walmart charges no setup or monthly subscription fees, and eligible new sellers can access its 2026 New-Seller Savings program. After your store goes live, you must opt in through the Payments page in Seller Center to receive the discounts.
But the goal shouldn’t be to build your business around one marketplace. Setting up clean product data, consistent SKUs, and clear inventory and fulfillment processes from the start makes it easier to manage Walmart alongside other sales channels. Multichannel solutions like UniCon can support that setup by helping keep products, inventory, and orders connected across marketplaces.

In this guide, we’ll cover how to start selling on Walmart Marketplace in 2026 and prepare your store for multichannel growth.

What You Need Before You Apply

Before applying, make sure your business, catalog, and fulfillment setup meet Walmart Marketplace’s current application requirements.
  • A copy of a personal ID. Walmart requires identification for the applicant or legal business representative and may request additional identity verification during the review process.
  • A Business Tax ID or Business License Number. Social Security Numbers are not accepted. Your legal business information should match your official documentation.
  • Your business entity classification. Be prepared to identify the legal structure under which your business operates. For the U.S. Marketplace, Walmart does not accept nonprofit organizations, sole proprietorships outside India, or Hindu Undivided Family entities. Review Walmart’s current business eligibility requirements before applying.
  • Supporting documents that verify your business name and address.
  • A history of marketplace or ecommerce success. Walmart uses your existing selling history to evaluate whether your business is prepared to meet its customer-service and fulfillment expectations.
  • Products generally need a valid GTIN, UPC, ISBN, or EAN. Walmart verifies product identifiers through GS1 or the applicable issuing authority. Eligible products without an identifier may qualify for a UPC or GTIN exemption.
  • A catalog that complies with Walmart’s Prohibited Products Policy. Your listings should contain accurate product information, appropriate identifiers, clear images, and products you are legally authorized to sell.
  • Fulfillment through Walmart Fulfillment Services or a B2C U.S. warehouse with returns capability. If you fulfill orders yourself, your operation must be able to ship orders, process returns, and meet Walmart’s delivery requirements.
  • The ability to meet Walmart’s Seller Performance Standards. Walmart currently evaluates cancellation, on-time delivery, valid tracking, seller response, negative feedback, return, item-not-received, and late-shipment rates.
Walmart verifies application information against official business records. Make sure names, addresses, registration details, and tax information match your documents exactly. Discrepancies may delay verification or prompt Walmart to request additional documentation.

What You Can Sell and What Needs Approval

Walmart Marketplace supports a wide range of product categories, but not every product can be listed automatically.Walmart restricts certain categories and product types to approved sellers. Your available selling privileges are based on your account, business information, performance, and compliance history. Check the Category approval section under Health and compliance in Seller Center before sourcing or listing restricted products.
  • Books
  • Class II or restricted medical devices
  • Ingestible products
  • Fragrances
  • Topical products
  • Luxury brands
  • Software
  • Halloween and select seasonal products
  • Custom content
  • Jewelry, watches, precious gemstones 
  • Currency, coins, and precious metals

For categories eligible for standard category approval, go to Health and compliance in Seller Center, find Category approval, and select Request approval. Some restricted categories, including certain medical devices and covered goods, use separate vetting processes. Review the applicable product policy before applying.

2026 Walmart Marketplace Fees at a Glance

Walmart doesn't charge setup or monthly subscription fees. Instead, Walmart takes a percentage of each sale, called a referral fee. If you use Walmart Fulfillment Services (WFS), you'll also pay Walmart to store, pack, and ship your products. 

A couple of things worth flagging before you price your catalog. Referral fees are tiered by category and, for many categories, by item price too. Check the Seller Center for your exact category rather than assuming a flat rate. And WFS storage fees escalate hard for slow-moving inventory, up to $7.50 per cubic foot for stock held over 450 days versus $0.75 normally, so it's worth watching anything that isn't turning over. 

Eligible sellers who go live after February 1, 2026 may qualify for Walmart’s 2026 New-Seller Savings program. The program offers tiered referral-fee discounts of 20% on the first $50,000 in GMV, 30% between $50,000 and $500,000, and 40% above $500,000. Eligible sellers can also receive 10% off WFS fulfillment fees until they reach $2,000 in WFS savings. The promotion runs through January 31, 2027, and participation is subject to Walmart’s eligibility requirements and program terms. Review the 2026 New-Seller Savings details before calculating your expected costs.

Fulfillment Options: Seller-Fulfilled vs. WFS

After reviewing the costs above, the next decision is how you'll actually fulfill Walmart orders. Your choice affects more than shipping. It also determines where inventory is stored, who manages returns, and how easily your fulfillment setup can support additional sales channels later.

Your fulfillment choice can also affect how you manage multiple sales channels. Whether you use your own warehouse, a 3PL, or WFS, you’ll need a way to keep inventory accurate and make sure orders reach the right fulfillment location.

As you add more channels, you’ll also need to manage product data, listings, inventory, and orders across platforms. A multichannel solution like UniCon can help keep these workflows connected as you grow.

The key is to choose a fulfillment setup that works for Walmart today and can support your multichannel operations later.

Think About Operations Early

As you plan your Walmart setup, it’s worth thinking beyond getting your first listings live. Three areas become harder to manage as your catalog and sales channels grow:

Inventory

Keep stock quantities accurate across channels to reduce overselling and stockouts.

Listings

Maintain product data, pricing, and marketplace-specific attributes without updating every channel separately.

Orders

Make sure orders from different marketplaces reach the right fulfillment location and can be tracked consistently.

You may be able to manage these manually at first, but the workflow becomes more complex as you add products, warehouses, or marketplaces. Planning how these areas will be managed early can save you from having to rebuild your process later.

How to Apply and Set Up

Application and onboarding times vary. Walmart says business verification may take anywhere from a few minutes to a few business days, while its 2026 New-Seller Savings guidance reports an average onboarding time of about 10 days. Once the required setup is complete and inventory has been added, account setup may take up to four hours to finalize. Additional identity or document reviews can extend the process, so respond promptly if Walmart requests more information.

Before You Publish Your Products

Make sure your listings are complete and easy for customers to understand:
  • Use accurate product names, descriptions, and key features.
  • Add clear, high-quality product images that follow Walmart’s image guidelines and requirements. Main images should generally use a seamless white background.
  • Choose the correct category and complete the relevant product attributes.
  • Keep pricing competitive.
  • Confirm inventory and fulfillment information are accurate before publishing.
After your products are live, Walmart’s Listing Quality tools can help you review content quality, pricing, shipping, inventory availability, ratings, and reviews.

Preparing Your Walmart Store for UniCon

Whether Walmart is your first marketplace or one of several channels you already sell on, a clean catalog and inventory setup makes it easier to manage and expand your multichannel business. Before using UniCon to coordinate products, inventory, and orders across channels, make sure your Walmart store is ready. Use this as a pre-flight checklist:

Incomplete or inconsistent product data can create extra work when mapping products across channels. Getting these areas in shape before you expand makes it easier to bring Walmart into a broader multichannel workflow.

With UniCon, Walmart can be used as a source marketplace alongside Amazon and Shopify, allowing you to bring your existing catalog into UniCon and expand it to other supported marketplaces without rebuilding your product data from scratch.

Final Thoughts

Walmart can be an important part of your ecommerce growth, but managing it becomes more complex when you start selling across multiple channels.

If your Walmart catalog has clean SKUs, complete product data, accurate inventory, and clear fulfillment workflows, you already have a stronger foundation for multichannel selling. The next challenge is keeping that information consistent as you add or manage other marketplaces.

If you’re managing Walmart alongside other channels, UniCon can help keep those workflows in one place. You can use Walmart, Amazon, or Shopify as a source channel, then manage product mapping, listings, inventory, warehouses, and orders as you expand to other supported marketplaces.

Multichannel selling still requires planning and ongoing management, but the right systems can reduce repetitive work and make it easier to keep your operations coordinated as your business grows.
