Beyond Amazon: adding Walmart and more marketplaces

This section is for Amazon sellers adding a second marketplace, most often Walmart. It covers how selling on Amazon and Walmart differs, from approval and fees to fulfillment and brand protection, and how to run both from one inventory without breaking either marketplace's rules.

Selling on Amazon and Walmart: how the two compare

Tier 05 of 05 · this section

Most sellers who add a second marketplace start with Walmart. It is the closest to Amazon in how it works: a third party marketplace on a major retailer's site, a fulfillment service that mirrors FBA, pay per click advertising, and a brand program for trademark owners. Walmart says its site reaches 120 million monthly visitors.

The first difference is access. Anyone with the right documents can open an Amazon seller account, individuals included. Walmart vets sellers: its beginner's guide says it looks for a history of marketplace or eCommerce success, and it requires a business tax ID, with a Social Security number not accepted. For an established Amazon seller, that track record is an advantage.

The second is fees. Amazon's Professional plan costs $39.99 a month plus referral fees by category. Walmart charges no setup or monthly fees, only a referral fee per sale that varies by category, which its beginner's guide puts between 6% and 15% of the total sales price, shipping included.

The third is product IDs. Walmart asks for GTIN or UPC codes with GS1 company prefixes, and offers a GTIN exemption for products without one, such as private label goods. Sellers who listed on Amazon with other codes may need new ones before applying.

Fulfillment works in parallel. Amazon's FBA ships with Prime; Walmart Fulfillment Services picks, packs and ships in two days or less, with no minimums or maximums, and takes returns in more than 4,600 stores or by mail. Both marketplaces also let you ship orders yourself, measured against performance standards.

Those standards differ in detail but not in spirit. Walmart asks for on-time delivery of 90% or above, valid tracking of 99% or above, cancellations of 2% or below and responses within 48 hours. Amazon measures order defects, late shipments and cancellations on its Account Health page. A seller who meets one usually meets the other.

Brand protection runs through separate programs. Amazon Brand Registry accepts a pending or registered trademark. Walmart Brand Portal requires a trademark registered with the USPTO, and handles copyright, trademark, patent and counterfeit claims. Each program unlocks its marketplace's Sponsored Brands ads.

Running both from one stock is possible in either direction. Amazon says Multi-Channel Fulfillment can fulfill orders placed on your websites and other sales channels from FBA inventory, and Walmart says WFS fulfills orders from other channels, naming Amazon, eBay, TikTok and your own website. Check each marketplace's rules for orders fulfilled by the other before you rely on it.

Listings carry over in principle but not in format. Walmart's catalog is built with Setup by Match, single items, bulk upload, the API or solution providers, and Walmart scores content quality and price competitiveness in its Pro Seller program. Most sellers start with their best Amazon products, rewritten for Walmart's attributes.

Both marketplaces have a buy box. On Amazon, the Offer Display features the most competitive offers on a product page, weighing price, delivery speed and stock.

On Walmart, sellers compete for what Walmart calls the Buy Box, and Walmart ties it to its Every Day Low Price approach: its Pricing Opportunities dashboard, Repricer tool and Success Hub's Match Buy Box price suggestions all exist to help third party sellers win it.

Fast delivery matters on both. Amazon's FBA offers carry the Prime badge; Walmart says WFS items earn the 2-day delivery and Fulfilled by Walmart tags, and are eligible for free shipping for Walmart+ members. On both marketplaces, handing fulfillment to the marketplace is the simplest way to meet shoppers' delivery expectations.

Competition has to be checked product by product. Walmart's vetting keeps its seller base selective, and its catalog of 170 million SKUs, by Walmart's count, sits alongside Walmart's own first party offers. Before listing, look at how many sellers already offer the product on each marketplace, and whether Walmart itself sells it.

Customer service standards are similar. Amazon's order defect rate target is under 1% for orders you ship yourself; Walmart asks for a negative feedback rate of 2% or below, a return rate of 6% or below and responses within 48 hours. With FBA or WFS, the marketplace handles most customer service and returns for you, though negative feedback still counts against you on Walmart.

Storage is a cost on both. Walmart's WFS charges a monthly storage fee by cubic feet and time stored; Amazon charges monthly storage and aged inventory surcharges on FBA stock. Sending each marketplace only what it will sell in the next weeks keeps both bills down.

Pricing needs one decision across both. Customers compare, and both marketplaces reward competitive prices: Amazon through the Featured Offer, Walmart through its price competitiveness score. A single price policy per product, adjusted for each marketplace's fees, avoids undercutting yourself.

A multichannel strategy starts with categories, not platforms. Check that your categories are open to you on Walmart and that none of your products fall under its Prohibited Products Policy, then compare each marketplace's referral fee for those categories. Some online shoppers search Walmart first for everyday goods, others Amazon; your own sales data on each platform will show which of your products each set of shoppers wants.

However the channels split, one ecommerce operation runs them: one product catalog, one inventory count, one customer service standard. Sellers who treat Walmart as a copy of Amazon, rather than a second store with its own rules, tend to struggle with both. Tools help here: listing connectors, repricers and inventory software can lower the cost of running two marketplaces, and Walmart lists solution providers for catalog setup.

The guides in this section cover Walmart in depth, from the application to Brand Portal, plus Amazon's own route to more countries: Remote Fulfillment with FBA, which offers US stock in Canada, Mexico and Brazil.

The pros and cons for an Amazon seller come down to this. Walmart's fee structure has no monthly subscription, its vetting favors sellers with a track record, and WFS gives items the same kind of fast delivery badge that Prime gives on Amazon. Against that, Walmart asks for GS1 product IDs and a registered trademark for its brand program, and every channel adds listings, stock and customer service to manage.

Walmart applies its referral fee to the total sales price, which it defines as the item price plus shipping and handling, gift wrap and other charges. Compare the two marketplaces on the same product with each one's fee tables, not on headline rates.

What changed for multichannel sellers in 2026

Changes in 2026 that affect sellers using Amazon inventory across channels: Amazon ended US prep in January, ended commingling in March, added a fuel surcharge on FBA in April and on Multi-Channel Fulfillment from May 2. January 1 March 31 April 17 May 2 no Amazon FBA prep commingling ends FBA fuel surcharge surcharge on MCF
Amazon's 2026 changes reach orders from other channels too

Amazon's 3.5% fuel and logistics surcharge on fulfillment fees started for FBA on April 17, 2026, and Amazon's fee pages say it took effect for Multi-Channel Fulfillment in the US and Canada, and for Buy with Prime in the US, from May 2, 2026. Sellers who fulfill Walmart or website orders from FBA stock pay it on those orders too.

Amazon also ended its US FBA prep service on January 1, 2026, and ended commingling on March 31, so every unit, whichever channel it sells on, arrives prepped and, for resellers, with an Amazon barcode label.

The per channel margin line

margin = price - referral fee - fulfillment - product cost - ads

Run it separately for each marketplace with its own fees. A product that pays on Amazon can lose money on Walmart, and the reverse.

The order to add a second marketplace

The order to add Walmart as an Amazon seller: check eligibility, prepare the catalog, apply, list best sellers, choose fulfillment, then protect the brand and advertise. Check Prepare Apply List Grow requirements catalog and IDs and verify best sellers first WFS, Brand Portal, ads
The catalog check comes before the application
  1. Check eligibility

    A business tax ID, documents matching IRS records, and a fulfillment setup that meets Walmart's performance standards.

  2. Prepare the catalog

    Remove anything on Walmart's Prohibited Products Policy, since Walmart says one prohibited item can get an application denied, and confirm GS1 product IDs.

  3. Apply and verify

    Walmart's onboarding covers business verification, payments, profile, shipping and returns, then items. Verification takes a few minutes to two business days.

  4. List your best sellers first

    Start with products that already sell well on Amazon, with complete Walmart attributes, images and competitive prices.

  5. Choose fulfillment

    WFS for Walmart's two day tags and hands off returns, your own warehouse, or a mix by item.

  6. Protect and advertise

    Register the brand in Walmart Brand Portal, then use Walmart Connect ads, including Sponsored Brands once the brand is registered.

How to tell whether a second marketplace is working

A second marketplace works when it adds profit without hurting the first. Six numbers show it:

The growth tier of the crest: the parcel stream thinned into one clean line along the shelf
NumberWhere it isWhat it tells you
Margin per channelEach marketplace's fee reportsWhether each channel pays on its own
Sales on the new channelWalmart Seller Center reportsWhether customers find you there
Stock coverInventory across bothWhether shared stock runs out
Performance metricsWalmart standards, Amazon Account HealthWhether service holds on both
Content qualityWalmart listing quality toolsWhether listings meet Walmart's bar
Ad spend by channelWalmart Connect, Amazon AdsWhether ads pay on each

Read them together. Sales on Walmart with falling stock cover on Amazon means the channels compete for the same units; plan reorders for both. Strong Walmart sales with weak margins usually point to fees on heavy items or advertising.

Watch customer data on both platforms as well: reviews, return reasons and buyer messages often show the same product problem twice, which makes it easier to fix at the source. And compare advertising results separately, since costs per click, shoppers and competition differ by marketplace.

Give a new marketplace a fair trial before judging it: complete listings, competitive prices and reliable fulfillment for at least a few months. Our Walmart Marketplace management service runs that trial with you.
