Walmart Marketplace vs Amazon: Which is right for your business?

Choosing between Walmart Marketplace vs Amazon is not a simple either-or decision. The smarter move is to understand how each platform works, then decide where your products will perform best.

This guide compares selling on Walmart vs Amazon with a side-by-side view of costs, fulfillment, requirements, tools and more. We’ll also show how marketplace integration with Channable keeps product data consistent and helps you scale across both without extra work.

Key Takeaways

• Amazon offers broad reach, mature tools and global scale, but competition is intense and costs add up
• Walmart has lower seller saturation, no monthly seller fee and strong brand trust with loyal shoppers
• Many teams get the best results by selling on both and centralizing product data, orders and ads with marketplace integration
• Your margins, catalog size and operations should drive the choice, not platform hype

Walmart Marketplace overview

Walmart Marketplace is a fast-growing online platform where third-party sellers list products alongside Walmart’s own inventory. They’re typically known for having sellers from the US on their marketplace but recently, they’ve begun a major push to bring U.K. and EU sellers to its global Marketplace in the US and its growing international marketplaces in Canada, Mexico, and Chile. Walmart also opened an office in London to help support U.K. and European sellers who would like to launch into online sales on the company’s marketplaces.

Selling here gives you recognition among Walmart’s loyal customer base (270 million in-store shoppers) and an online shopping experience built for value and convenience.

Strengths to consider

• No monthly seller fee. You pay referral fees on each sale
• Lower competition in many categories compared with Amazon
• Fast onboarding steps once approved, with a clean seller center
• Returns options online or in store which builds buyer confidence
• Walmart Fulfillment Services (WFS) for 2-day delivery badges and reliable shipping

Challenges to plan for

• Selective approval: You need a business tax ID, proof of online selling history and compliant product data
• Regional focus: Walmart.com primarily serves customers in the United States with separate portals for Canada, Chile, and Mexico. Although please note Walmart has embarked on a major push to bring EU sellers to its international marketplaces across the Atlantic.
• Category limits: Certain categories require pre-approval, and listing standards are strict

Getting started

Expect a sequence of account creation, business verification, payment setup with a supported processor, and shipping plus returns configuration. You can add items one by one, upload in bulk with spreadsheets or connect via an integration partner to sync product data in real time. If you already work in a PIM, ERP or eCommerce platform, using a Walmart Marketplace integration keeps your catalog consistent without manual edits.

Amazon overview

Amazon is the most established marketplace for scale, with a massive customer base and deep tooling for operations, advertising and analytics. Prime remains a major driver of loyalty with over 220 million users worldwide.

Strengths to consider

• Global reach and a very large audience
• Fulfilled by Amazon (FBA) for fast shipping and Prime eligibility
• Rich ad formats and mature campaign controls
• Brand tools such as Brand Registry, A+ content and experiments for testing

Challenges to plan for

• High competition across most categories
• Monthly professional plan for serious sellers, plus referral and fulfillment fees
• Strict selling rules that require tight operational control

Getting started

Registration is open to most sellers. Verification can include ID checks and additional reviews. You can start with merchant fulfillment, then migrate products into FBA depending on your sales volume. Ad products and analytics become more useful as your catalog grows and reviews accumulate.

Walmart Marketplace vs Amazon: Cost comparison

To check if selling on any marketplace is actually worth it, start by calculating your margins. Here’s what to compare:

• Monthly fees. Amazon’s professional plan is a fixed cost, while Walmart does not charge a monthly seller fee.
• Referral fees. Both platforms set category-based percentages, with some tiering by price level on Walmart.
• Fulfillment fees. Check FBA vs WFS prices by size and weight. Handling, pick and pack and returns are included.
• Storage fees. Peak season surcharges and aged inventory rules can cut into your margins on slow-selling products.
• Advertising. Budget for Sponsored Products and other formats. CPCs vary by category and season.

Fulfillment and logisitics

Fast, reliable delivery drives visibility and conversion on both platforms. The right setup depends on your catalog, cash flow and how much control you want over logistics.

FBA vs WFS at a glance

Feature	Fulfilled by Amazon (FBA)	Walmart Fulfillment Services (WFS)
Delivery badge	Prime 1–2 day	2-day delivery
Network reach	Global (175+ centers)	US-based
Fees	Storage + fulfillment + returns	Weight- and size-based

What do I need to get started?

Before you can sell on either platform, you’ll need to show that your business is legitimate and that you can deliver a reliable buying experience.

Requirement	Walmart Marketplace	Amazon
Business type	US-registered business with tax ID	Individual or business with verified ID and tax info
Selling history	Proof of prior online sales	Not required but helps credibility
Account setup	Manual approval process	Instant signup for most sellers
Fulfillment	US warehouse or WFS	FBA or self-fulfillment
Important KPIs	On-time shipping and valid tracking	Low defect and cancellation rates

For both platforms, keep orders trackable, respond quickly to customers and keep your stock data accurate. The better you maintain your data, the better your listings perform.

Which products can I sell?

Both marketplaces attract different shoppers, so it’s worth testing SKUs to align your catalog with what people actually buy there.

Category strengths	Walmart Marketplace	Amazon
Best for	Grocery, baby, pet, toys, seasonal and household essentials	Tech accessories, home goods, private-label beauty and wellness
Typical buyer	Value-driven, family-focused, in-store pickup users	Convenience-focused, Prime members, strong review readers
Content style	Clear pricing, simple descriptions, fast delivery tags	Rich brand pages, detailed A+ listings

What about advertising?

Once your listings look good and your prices are competitive, ads can help you reach more shoppers. Both marketplaces offer pay-per-click formats, but Amazon advertising works a little differently than advertising on Walmart Marketplace.

Platform	Ad formats	Typical costs	What helps performance
Amazon	Amazon Sponsored Ads, Brands, and Display	Usually higher CPCs in busy categories	Strong reviews, competitive pricing, Prime eligibility
Walmart	Sponsored Products and other placements via Walmart Connect ad platform	Often lower CPCs, depending on category	Competitive pricing, fast delivery, in-stock items

Use Sponsored Products ads for your best sellers. Leave out items with low stock or thin margins, and make sure your ad text always matches your latest prices and offers. Keep an eye on what’s selling so your budget goes where it really works. Using a PPC optimization tool can help you apply a consistent advertising strategy and improve your ROAS across both platforms.
