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

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.
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 |
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.
