A product can perform exceptionally well on one marketplace and struggle on another—even when the price, images, and descriptions are identical.
We’ve seen this happen repeatedly.
One home goods retailer expanded from Amazon to Walmart expecting similar sales patterns. Instead, they discovered that products buried beneath thousands of competitors on Amazon were receiving significantly more visibility on Walmart simply because the marketplace wasn’t as saturated.
Choosing between Amazon and Walmart isn’t just about traffic. It affects advertising costs, fulfillment strategy, catalog management, operational workload, and ultimately profit margins.
For sellers planning marketplace expansion, understanding the differences between Amazon and Walmart has become increasingly important.
Although both platforms allow third-party sellers to reach millions of online shoppers, their operating environments are fundamentally different.
Amazon functions as a massive global marketplace with intense competition across nearly every category.
Walmart Marketplace remains more selective, with fewer sellers and lower competition in many product segments.
This distinction influences everything from product discoverability to customer acquisition costs.
| Factor | Amazon Marketplace | Walmart Marketplace |
|---|---|---|
| Seller Base | Very large | More selective |
| Competition Level | Extremely high | Moderate |
| Customer Traffic | Massive global reach | Strong U.S. audience |
| Approval Process | Relatively straightforward | More selective |
| Fulfillment Program | Amazon FBA | Walmart Fulfillment Services (WFS) |
| Advertising Competition | High | Lower in many categories |
| Brand Visibility | Challenging for new sellers | Often easier |
| International Reach | Extensive | Primarily U.S.-focused |
The first major difference appears before the first product is even listed.
Amazon allows most businesses to create seller accounts relatively quickly.
The onboarding process typically involves:
For many sellers, approval happens without significant delays.
Walmart follows a more selective approach.
Applications are reviewed based on factors such as:
As a result, some sellers are approved immediately while others may not qualify.
This selective model contributes to Walmart’s lower seller saturation.
Competition often determines how quickly a new seller gains traction.
Amazon offers enormous customer traffic.
However, that traffic attracts millions of sellers.
Consider a common product category such as kitchen accessories.
A search may return thousands of competing listings featuring:
New sellers frequently struggle to gain visibility without substantial advertising investments.
Walmart’s marketplace generally contains fewer competing sellers.
This creates opportunities for:
Many sellers discover they can achieve first-page placement more easily than on Amazon.
That doesn’t guarantee sales, but it can reduce customer acquisition costs.
Marketplace fees directly affect profitability.
Amazon sellers typically encounter:
For large catalogs, these expenses can accumulate quickly.
Long-term storage fees alone can impact margins when inventory forecasting isn’t managed carefully.
Walmart generally charges:
Notably, Walmart does not charge a monthly seller subscription fee for marketplace participation.
For some businesses, this results in a lower barrier to entry.
However, overall profitability depends on product category, fulfillment strategy, and advertising spend.
Fulfillment capabilities significantly influence customer satisfaction and marketplace performance.
Benefits include:
For many sellers, FBA simplifies operations considerably.
The trade-off is increased fee complexity.
Advantages include:
While WFS continues to grow, Amazon’s fulfillment network remains larger and more mature.
Businesses heavily dependent on logistics efficiency may find Amazon’s infrastructure difficult to match.
Many marketplace comparisons focus on traffic and fees.
Operational complexity often receives less attention.
Yet this is where many sellers encounter problems.
Uploading 100 products manually is manageable.
Maintaining 100,000 SKUs across multiple marketplaces is an entirely different challenge.
Common catalog issues include:
When products exist simultaneously on Amazon, Walmart, Shopify, and additional channels, data accuracy becomes critical.
At India Data Entry Services, we’ve worked with retailers managing large-scale product catalogs where a small data inconsistency triggered inventory discrepancies across multiple marketplaces.
As catalog size grows, marketplace management becomes increasingly dependent on structured backend operations rather than front-end selling tactics.
Amazon’s advertising ecosystem is highly developed.
Sellers can use:
The downside is increased competition.
Popular categories often experience significant bid inflation.
Walmart’s advertising platform continues expanding.
Benefits often include:
Many brands use Walmart advertising as a complementary acquisition channel rather than a direct replacement for Amazon ads.
Neither platform is universally superior.
The right choice depends on product category, margins, operational resources, and long-term growth objectives.
A common misconception is that sellers must choose one marketplace.
Increasingly, successful ecommerce businesses operate across both.
The strategy typically looks like this:
This approach reduces dependence on a single marketplace while increasing customer reach.
One retailer we worked with initially sold exclusively on Amazon. After expanding to Walmart and cleaning up product data inconsistencies across channels, they gained additional sales opportunities without dramatically increasing operational overhead.
The challenge wasn’t marketplace expansion itself.
It was maintaining accurate product information across every selling channel.
Amazon remains the dominant marketplace in terms of scale, traffic, and fulfillment infrastructure.
Walmart Marketplace offers a less crowded environment where sellers can often gain visibility more easily.
For businesses evaluating marketplace expansion, the decision should extend beyond traffic numbers. Competition levels, fulfillment costs, catalog complexity, advertising expenses, and operational capacity all influence marketplace success.
Many growing ecommerce brands ultimately discover that the strongest position comes from maintaining a presence on both platforms while investing in accurate catalog management and marketplace operations behind the scenes.
